adjacent to and included with the Premises. Landlord shall incur no expense nor
have any obligation of any kind whatsoever in connection with maintenance of the

Landlord from mechanics' liens, materialmen's liens or any other liens. In any
event, Tenant shall pay, when due, all claims for labor or materials furnished
to or for Tenant at or for use in the Premises. Tenant shall not permit any
mechanics' or materialmen's liens to be levied against the Premises for any

8.    INSURANCE; INDEMNITY.

      8.1   INSURING PARTY. As used in this Article 8, the term "insuring party"
shall mean the party who has the obligation to obtain the insurance required
hereunder. The insuring party in this case shall be designated in Article 20.
Whether the insuring party is the Landlord or the Tenant, Tenant shall, as
additional rent for the Premises, pay the cost of all insurance
required hereunder. If Landlord is the insuring party Tenant shall, within ten
(10) days following demand by Landlord, reimburse Landlord for the cost of
the insurance so obtained.

      8.2   LIABILITY INSURANCE. The Tenant shall obtain and keep in force
during the term of this Lease a policy of comprehensive public liability
insurance insuring Landlord and Tenant against any liability arising out of the
ownership, use, occupancy or maintenance of the Premises and all areas
appurtenant thereto. Such insurance shall be in an amount of not less than
$1,000,000 for injury to or death of one person in any one accident or occur-
rence and in an amount of not less than $1,000,000 for injury to or death of
more than one person in any one accident or occurrence. Such insurance shall
further insure Landlord and Tenant against liability for property damage of at
least $100,000. The limits of said insurance shall not, however, limit the
liability of Tenant hereunder. In the event that the Premises constitute a part
of a larger property said insurance shall have a Landlord's Protective Liability
endorsement attached thereto. If the Tenant shall fail to procure and maintain
said insurance the Landlord may, but shall not be required to, procure and
maintain the same, but at the expense of Tenant.

      8.3   PROPERTY INSURANCE. The insuring party shall obtain and keep in
force during the term of this Lease a policy or policies of insurance covering
loss or damage to the Premises, in the amount of the full replacement value
thereof, providing protection against all perils included within the classifica-
tion of fire, extended coverage, vandalism, malicious mischief, special extended
perils (all risk) and sprinkler leakage. Said insurance shall provide for pay-
ment for loss thereunder to Landlord or to the holder of a first mortgage or
deed of trust on the Premises. If the insuring party shall fail to procure and
maintain said insurance the other party may, but shall not be required to,
procure and maintain the same, but at the expense of Tenant.

      8.4   INSURANCE POLICIES. Insurance required hereunder shall be in
companies rated A+ AAA or better in "Best's Insurance Guide". The insuring party
shall deliver prior to possession to the other party copies of policies of such
insurance or certificates evidencing the existence and amounts of such insurance
with loss payable clauses satisfactory to Landlord. No such policy shall be
cancellable or subject to reduction of coverage or other modification except
after ten (10) days' prior written notice to Landlord. If Tenant is the insuring
party, Tenant shall, within ten (10) days prior to the expiration of such
policies, furnish Landlord with renewals or "binders" thereof, or Landlord may
order such insurance and charge the cost thereof to Tenant, which amount shall
be payable by Tenant upon demand. Tenant shall not do or permit to be done
anything which shall invalidate the insurance policies referred to in Article
8.3. Tenant shall forthwith, upon Landlord's demand, reimburse Landlord for any
additional premiums attributable to any act or omission or operation of Tenant
causing such increase in the cost of insurance. If Landlord is the insuring
party, and if the insurance policies maintained hereunder cover other
improvements in addition to the Premises, Landlord shall deliver to Tenant a
written statement setting forth the amount of any such insurance cost increase
and showing in reasonable detail the manner in which it has been computed.

      8.5   WAIVER OF SUBROGATION. Tenant and Landlord each waives any and all
rights of recovery against the other, or against the officers, employees, agents
and representatives of the other, for loss of or damage to such waiving party or
its property or the property of others under its control, where such loss or
damage is insured against under any insurance policy in force at the time of
such loss or damage. Tenant and Landlord shall, upon obtaining the policies of
insurance required hereunder, give notice to the insurance carriers that the
foregoing mutual waiver of subrogation is contained in this Lease.

      8.6   HOLD HARMLESS. Tenant shall indemnify, defend and hold Landlord
harmless from any and all claims arising from Tenant's use of the Premises or
from the conduct of its business or from any activity, work or things which may
be permitted or suffered by Tenant in or about the Premises and shall further
indemnify, defend and hold Landlord harmless from and against any and all claims
arising from any breach or default in the performance of any obligation on
Tenant's part to be performed under the provision of this Lease or arising from
any negligence of Tenant or any of its agents, contractors, employees or
invitees and from any and all costs, attorneys' fees, expenses and liabilities
incurred in the defense of any such claim or any action or proceeding brought
thereon. Tenant hereby assumes all risk of damage to property or injury to
persons in or about the Premises from any cause, and Tenant hereby waives all
claims in respect thereof against Landlord, excepting where said damage arises
out of negligence of Landlord.

      8.7   EXEMPTION OF LANDLORD FROM LIABILITY. Tenant hereby agrees that
Landlord shall not be liable for injury to Tenant's business or any loss of
income therefrom or for damage to the goods, wares, merchandise or other
property of Tenant, Tenant's employees, invitees, customers, or any other person
in or about the Premises; nor, unless through its negligence, shall Landlord be
liable for injury to the person of Tenant, Tenant's employees, agents or
contractors and invitees, whether such damage or injury is caused by or results
from fire, steam, electricity, gas, water or rain, or from the breakage,

                              (PAGE 2 NET-NET-NFT)

<PAGE>

leakage, obstruction or other defects of pipes, sprinklers, wires, appliances,
plumbing, air conditioning or lighting fixtures, or from any other cause,
whether the said damage or injury results from conditions arising upon the
Premises or upon other portions of the building of which the Premises are a
part, or from other sources or places, and regardless of whether the cause of
such damage or injury or the means of repairing the same is inaccessible to
Landlord or Tenant. Landlord shall not be liable for any damages arising from
any act or neglect of any other tenant, if any, of the building in which the
Premises are located.

9.    DAMAGE OR DESTRUCTION

      9.1   In the event the improvements on the Premises are damaged or
destroyed, partially or totally, from any cause whatsoever, whether or not such
damage or destruction is covered by any insurance required to be maintained
under Article 8, the Tenant shall repair, restore, and rebuild the Premises to
their condition existing immediately prior to such damage or destruction and
this Lease shall continue in full force and effect. Such repair, restoration and
rebuilding (all of which an herein called the "repair") shall be commenced
within a reasonable time after such damage or destruction and shall be
diligently prosecuted to completion. There shall be no abatement of rent or of
any other obligation of Tenant hereunder by reason of such damage or
destruction. The proceeds of any insurance maintained under Article 8.3 shall be
made available to Tenant for payment of the cost and expanse of the repair,
provided, however, that such proceeds may be made available to Tenant subject to
reasonable conditions including, but not limited to, architect's certification
of costs and retention of a percentage of such proceeds pending final notice of
completion. In the event that such proceeds are not made available to Tenant
within ninety (90) days after such damage or destruction, Tenant shall have the
option for thirty (30) days, commencing on the expiration of such ninety (90)
day period of cancelling this Lease. If Tenant shall exercise such option,
Tenant shall have no further obligation hereunder and shall have no further
claim against Landlord; provided, however, that Landlord shall return to Tenant
so much of Tenant's security deposit as has not theretofore been applied by
Landlord. Tenant shall exercise such option by written notice to Landlord within
said thirty (30) day period. In the event that the insurance proceeds are
insufficient to cover the cost of the repair, then any amount in excess thereof
required to complete the repair shall be paid by Tenant.

      9.2   DAMAGE NEAR END OF TERM. If the Premises are partially destroyed or
damaged during the last six (6) months of the term of this Lease, Landlord may,
at Landlord's option, cancel and terminate this Lease as of the date of
occurrence of such damage by giving written notice to Tenant of Landlord's
election to do so within thirty (30) days after the date of occurrence of such
damage.

      9.3   PRORATIONS. Upon termination of this Lease pursuant to this Article
9, a pro rata adjustment of rent based upon a thirty (30) day month shall be
made. Landlord shall, in addition, return to Tenant so much of Tenant's security
deposit as has not theretofore been applied by Landlord.

10.   REAL PROPERTY TAXES.

      10.1  PAYMENT OF TAXES. Tenant shall pay all real property taxes
applicable to the Premises during the term of this Lease. All such payments
shall be made at least ten (10) days prior to the delinquency date of such
payment. Tenant shall promptly furnish Landlord with satisfactory evidence that
such taxes have been paid. If any such taxes paid by Tenant shall cover any
period of the time prior to or after the expiration of the term hereof, Tenant's
share of such taxes shall be equitably prorated to cover only the period of time
within the tax fiscal year during which this Lease shall be in effect, and
Landlord shall reimburse Tenant to the extent required. If Tenant shall fail to
pay any such taxes, Landlord shall have the right to pay the same, in which case
Tenant shall repay such amount to Landlord with Tenant's next rent installment
together with interest at the rate of ten (10%) percent per annum.

      10.2  DEFINITION OF "REAL PROPERTY" TAXES. As used herein, the term "real
property tax" shall include any form of assessment, license fee, rent tax, levy,
penalty, or tax (other than inheritance or estate taxes), imposed by any
authority having the direct or indirect power to tax, including any city,
county, state or federal government, or any school, agricultural, lighting,
drainage or other improvement district thereof, as against any legal or
equitable interest of Landlord in the Premises or in the real property of which
the Premises are a part, as against Landlord's right to rent or other income
therefrom, or as against Landlord's business of leasing the Premises, and,
Tenant shall pay any and all charges and fees which may be imposed by the EPA or
other similar government regulations or authorities.

      10.3  JOINT ASSESSMENT. If the Premises are not separately assessed,
Tenant's liability shall be an equitable proportion of the real property taxes
for all of the land and improvements included within the tax parcel assessed,
such proportion to be determined by Landlord from the respective valuations
assigned in the assessor's work sheets or such other information as may be
reasonably available. Landlord's reasonable determination thereof, in good
faith, shall be conclusive.

      10.4  PERSONAL PROPERTY TAXES.

            (a) Tenant shall pay prior to delinquency all taxes assessed against
and levied upon leasehold improvements, trade fixtures, furnishings, equipment
and all other personal property of Tenant contained in the Premises or
elsewhere. Tenant shall cause said leasehold improvements, trade fixtures,
furnishings, equipment and all other personal property to be assessed and billed
separately from the real property of Landlord.

            (b) If any of Tenant's said personal property shall be assessed with
Landlord's real property, Tenant shall pay Landlord the taxes attributable to
Tenant within ten (10) days after receipt of a written statement setting forth
the taxes applicable to Tenant's property.

11.   COMMON AREAS. When, in fact, there are Common Areas, then the following
shall apply:

      11.1  DEFINITIONS. The phrase "Common Areas" means all areas and
facilities outside the Premises that are provided and designated for general use
and convenience of Tenant and other tenants and their respective officers,
agents and employees, customers, and invitees. Common Areas include (but are not
limited to) pedestrian sidewalks, landscaped areas, roadways, parking areas and
railroad tracks, if any. Landlord reserves the right from time to time to make
changes in the shape, size, location, number, and extent of the land and
improvements constituting the Common Areas. Landlord may designate from time to
time additional parcels of land for use as a part thereof; and any additional
land so designated by Landlord for such use shall be included until such
designation is revoked by Landlord.

      11.2  MAINTENANCE. During the term of this Lease, Landlord shall operate,
manage, and maintain the Common Areas so that they are clean and free from
accumulations of debris, filth, rubbish, and garbage. The manner in which such
Common Areas shall be so maintained, and the expenditures for such maintenance,
shall be at the sole discretion of Landlord, and the use of the Common Areas
shall be subject to such reasonable regulations and changes therein as Landlord
shall make from time to time, including (but not by way of limitation) the right
to close from time to time, if necessary, all or any portion of the Common Areas
to such extent as may be legally sufficient, in the opinion of Landlord's
counsel, to prevent a dedication thereof or the accrual of rights of any person
or of the public therein, or to close temporarily all or any portion of such
Common Areas for such purposes.

      11.3  TENANT'S RIGHTS AND OBLIGATIONS. Landlord hereby grants to Tenant,
during the term of this Lease, the license to use, for the benefit of Tenant and
its officers, agents, employees, customers, and invitees, in common with the
others entitled to such use, the Common Areas as they from time to time exist,
subject to the rights, powers, and privileges herein reserved to Landlord.
Storage, either permanent or temporary, of any materials, supplies or equipment
in the Common Area is strictly prohibited. Should Tenant violate this provision
of the Lease, then in such event, Landlord may, at his option either terminate
this Lease or, without notice to Tenant, remove said materials, supplies or
equipment from the Common Area and place such items in storage, the cost thereof
to be reimbursed by Tenant within ten (10) days from receipt of a statement
submitted by Landlord. All subsequent costs in connection with the storage of
said items shall be paid to Landlord by Tenant as accrued. Failure of Tenant to
pay these charges within ten (10) days from receipt of statement shall
constitute a breach of this Lease. Tenant and its officers, agents, employees,
customers and invitees shall park their motor vehicles only in areas designated
by Landlord for that purpose from time to time. Within five (5) days after
request from Landlord, Tenant shall furnish to Landlord a list of the license
numbers assigned to its motor vehicles, and those of its officers, agents and
employees. Tenant shall not at any time park or permit the parking of motor
vehicles, belonging to it or to others, so as to interfere with the pedestrian
sidewalks, roadways, and loading areas, or in any portion of the parking areas
not designed by Landlord for such use by Tenant. Tenant agrees that receiving
and shipping of goods and merchandise and all removal of refuse shall be made
only by way of the loading areas constituting part of the Premises. Tenant shall
repair, at its cost, all deteriorations or damages to the Common Areas,
occasioned by its lack of ordinary care.

      11.4  CONSTRUCTION. Landlord, while engaged in constructing improvements
or making repairs or alterations in or about the Premises or in their vicinity,
shall have the right to meke reasonable use of the Common Areas.

12.   UTILITIES. Tenant shall pay for all water, gas, heat, light, power,
telephone and other utilities and services supplied to the Premises, together
with any taxes thereon. If any such services are not separately metered to
Tenant, Tenant shall pay a reasonable proportion to be determined by Landlord of
all charges jointly metered with other premises.

13.   ASSIGNMENT AND SUBLETTING.

      13.1  LANDLORD'S CONSENT REQUIRED. Tenant shall not voluntarily or by
operation of law assign, transfer, mortgage, sublet, or otherwise transfer or
encumber all or any part of Tenant's interest in this Lease or in the Premises
without Landlord's prior written consent, which Landlord shall not reasonably
withhold. Any attempted assignment, transfer, mortgage, encumbrance, or
subletting without such consent shall be void and shall constitute a breach of
the Lease. Any transfer of Tenant's interest in this Lease or in the Premises
from Tenant by merger, consolidation, or liquidation,

                              (PAGE 3 NET-NET-NET)

<PAGE>

or by any subsequent change in the ownership of thirty (30%) percent or more of
the capital stock of Tenant shall be deemed a prohibited assignment within the
meaning of this Article 13.

      13.2  NO RELEASE OF TENANT. Regardless of Landlord's consent, no
subletting or assignment shall release Tenant of Tenant's obligation to pay the
rent and to perform all other obligations to be performed by Tenant hereunder
for the term of this Lease. The acceptance of rent by Landlord from any other
person shall not be deemed to be a waiver by Landlord of any provision hereof.
Consent to one assignment or subletting shall not be deemed consent to any
subsequent assignment or subletting.

14.   DEFAULTS; REMEDIES.

      14.1  DEFAULTS. The occurrence of any one or more of the following events
shall constitute a default and breach of this Lease by Tenant:

            (a) The vacating or abandonment of the Premises by Tenant.

            (b) The failure by Tenant to make any payment of rent or any other
payment required to be made by Tenant hereunder, as and when due, where such
failure shall continue for a period of three (3) days after written notice
thereof from Landlord to Tenant.

            (c) The failure by Tenant to observe or perform any of the
covenants, conditions or provisions of this Lease to be observed or performed by
Tenant, other than described in Paragraph (b) above, where such failure shall
continue for a period of thirty (30) days after written notice thereof from
Landlord to Tenant; provided, however, that if the nature of Tenant's default is
such that more then thirty (30) days are reasonably required for its cure, then
Tenant shall not be deemed to be in default if Tenant commenced such cure within
said thirty (30) day period and thereafter diligently prosecutes such cure to
completion.

            (d) (i) The making by Tenant of any general assignment, or general
arrangement for the benefit of creditors; (ii) the filing by or against Tenant
of a petition to have Tenant adjudged a bankrupt or a petition for
reorganization or arrangement under any law relating to bankruptcy (unless, in
the case of a petition filed against Tenant, the same is dismissed within sixty
(60) days); (iii) the appointment of a trustee or receiver to take possession of
substantially all of Tenant's assets located at the Premises or of Tenant's
interest in this Lease, where possession is not restored to Tenant within thirty
(30) days; or (iv) the attachment, execution or other judicial seizure of
substantially all of Tenant's assets located at the Premises or of Tenant's
interest in this Lease, where such seizure is not discharged within thirty (30)
days.

      14.2  REMEDIES IN DEFAULT. In the event of any such default or breach by
Tenant, Landlord may at any time thereafter, with or without notice or demand
and without limiting Landlord in the exercise of any right or remedy which
Landlord may have by reason of such default or breach:

            (a)Terminate Tenant's right to possession of the Premises by any
lawful means, in which case this Lease shall terminate and Tenant shall
immediately surrender possession of the Premises to Landlord. In such event
Landlord shall be entitled to recover from Tenant all damages incurred by
Landlord by reason of Tenant's default including, but not limited to, the cost
of recovering possession of the Premises; expenses of reletting, including
necessary renovation and alteration of the Premises, reasonable attorney's fees,
and any real estate commission actually paid; the worth at the time of award by
the court having jurisdiction thereof of the amount by which the unpaid rent for
the balance of the term after the time of such award exceeds the amount of such
rental loss for the same period that Tenant proves could be reasonably avoided;
and that portion of the leasing commission paid by Landlord applicable to the
unexpired term of this Lease. Unpaid installments of rent or other sums shall
bear interest from the date due at the rate of ten (10%) percent per annum. In
the event Tenant shall have abandoned the Premises, Landlord shall have the
option of (i) retaking possession of the Premises and recovering from Tenant the
amount specified in this Article 14.2(a), or (ii) proceeding under Article
14.2(b).

            (b)Maintain Tenant's right to possession, in which case this Lease
shall continue in effect whether or not Tenant shall have abandoned the
Premises. In such event. Landlord shall be entitled to enforce all of Landlord's
rights and remedies under this Lease, including the right to recover the rent as
it becomes due hereunder.

            (c)Pursue any other remedy now or hereafter available to Landlord
under the laws or judicial decisions of the State in which the Premises are
located.

      14.3  DEFAULT BY LANDLORD. Landlord shall not be in default unless
Landlord fails to perform obligations required of Landlord within a reasonable
time, but in no event later then thirty (30) days after written notice by Tenant
to Landlord and to the holder of any first mortgage or deed of trust covering
the Premises whose name and address shall have theretofore been furnished to
Tenant in writing, specifying wherein Landlord has failed to perform such
obligation; provided, however, that if the nature of Landlord's obligation is
such that more than thirty (30) days are required for performance then Landlord
shall not be in default if Landlord commences performance within such thirty
(30) day period and thereafter diligently prosecutes the same to completion.

      14.4  LATE CHARGES. Tenant hereby acknowledges that late payment by Tenant
to Landlord of rent and other sums due hereunder will cause Landlord to incur
costs not contemplated by this Lease, the exact amount of which will be
extremely difficult to ascertain. Such costs include, but are not limited to,
processing and accounting charges, and late charges which may be imposed on
Landlord by the terms of any mortgage or trust deed covering the Premises.
Accordingly, if any installment of rent or any other sum due from Tenant shall
not be received by Landlord or Landlord's designee within ten (10) days after
written notice that said amount is past due, then Tenant shall pay to Landlord a
late charge equal to ten (10%) percent of such overdue amount. The parties
hereby agree that such late charge represents a fair and reasonable estimate of
the cost Landlord will incur by reason of late payment by Tenant. Acceptance of
such late charge by Landlord shall in no event constitute a waiver of Tenant's
default with respect to such overdue amount, nor prevent Landlord from
exercising any of the other rights and remedies granted hereunder.

15.   CONDEMNATION. If the Premises or any portion thereof are taken under the
power of eminent domain, or sold by Landlord under the threat of the exercise of
said power (all of which is herein referred to as "condemnation"), this Lease
shall terminate as to the part so taken as of the date the condemning authority
takes title or possession, whichever occurs first. If more than twenty-five
(25%) percent of the floor area of any buildings on the premises, or more than
twenty-five (25%) percent of the land area of the Premises not covered with
buildings is taken by condemnation, either Landlord or Tenant may terminate
this Lease as of the date the condemning authority takes possession by notice in
writing of such election within twenty (20) days after Landlord shall have
notified Tenant of the taking or, in the absence of such notice, then within
twenty (20) days after the condemning authority shall have taken possession.

      If this Lease is not terminated by either Landlord or Tenant then it shall
remain in full force and effect as to the portion of the Premises remaining,
provided the rental shall be reduced in proportion to the floor area of the
buildings taken within the Premises as bears to the total floor area of all
buildings located on the Premises. In the event this Lease is not so terminated
then Landlord agrees, at Landlord's sole cost, to as soon as reasonably possible
restore the Premises to a complete unit of like quality and character as existed
prior to the condemnation. All awards for the taking of any part of the Premises
or any payment made under the threat of the exercise of power of eminent domain
shall be the property of Landlord, whether made as compensation for diminution
of value of the leasehold or for the taking of the fee or as severance damages;
provided, however, that Tenant shall be entitled to any award for loss of or
damage to Tenant's trade fixtures and removable personal property.

16.   GENERAL PROVISIONS.

      16.1  OFFSET STATEMENT.

            (a) Tenant shall at any time upon not less than ten (10) days' prior
written notice from Landlord execute, acknowledge and deliver to Landlord a
statement in writing (i) certifying that this Lease is unmodified and in full
force and effect (or, if modified, stating the nature of such modification and
certifying that this Lease, as so modified, is in full force and effect) and the
date to which the rent, security deposit, and other charges are paid in advance,
if any, and (ii) acknowledging that there are not, to Tenant's knowledge, any
uncured defaults on the part of Landlord hereunder, or specifying such
defaults, if any, which are claimed. Any such statement may be conclusively
relied upon by any prospective purchaser or encumbrancer of the Premises.

            (b) Tenant's failure to deliver such statement within such time
shall be conclusive upon Tenant (i) that this Lease is in full force and effect,
without modification except as may be represented by Landlord, (ii) that there
are no uncured defaults in Landlord's performance, and (iii) that not more than
one (1) month's rent has been paid in advance.

            (c) If Landlord desires to finance or refinance the Premises, or any
part thereof, Tenant hereby agrees to deliver to any lender designated by
Landlord such financial statements of Tenant as may be reasonably required by
such lender. Such statements shall include the past three (3) years' financial
statements of Tenant. All such financial statements shall be received by
Landlord in confidence and shall be used only for the purposes herein set forth.

only the owner or owners at the time in question of the fee title or a tenant's
interest in a ground lease of the Premises. In the event of any transfer of such
title or interest, Landlord herein named (and in case of any subsequent
transfers the then grantor) shall be relieved from and after the date of such
transfer of all liability as respects Landlord's obligations thereafter to be
performed, provided that any funds in the hands of Landlord or the then grantor
at the time of such transfer, in which Tenant has an interest, shall be
delivered to the grantee. The obligations contained in this Lease to be
performed by Landlord shall, subject as aforesaid, be binding on Landlord's
successors and assigns, only during their respective periods of ownership.

      16.3  SEVERABILITY. The invalidity of any provision of this Lease, as
determined by a court of competent jurisdiction, shall in no way affect the
validity of any other provision hereof.

      16.4  INTEREST ON PAST-DUE OBLIGATIONS. Except as expressly herein
provided, any amount due to Landlord not paid when due shall bear interest at

prior agreement or understanding pertaining to any such matter shall be
effective. This Lease may be modified in writing only, signed by the parties in
interest at the time of the modification.

deemed a waiver of any other provision hereof or of any subsequent breach by
Tenant of the same or any other provision. Landlord's consent to or approval of
any act shall not be deemed to render unnecessary the obtaining of Landlord's
consent to or approval of any subsequent act by Tenant. The acceptance of rent
hereunder by Landlord shall not be a waiver of any preceding breach by Tenant of
any provision hereof, other than the failure of Tenant to pay the particular
rent so accepted, regardless of Landlord's knowledge of such preceding breach at
the time of acceptance of such rent.

      16.9  RECORDING. Tenant shall not record this Lease. Any such recordation
shall be a breach under this Lease.

consent of Landlord, such occupancy shall be a tenancy from month to month at a

hereunder, and upon the terms hereof applicable to month-to-month tenancy.

      16.11 CUMULATIVE REMEDIES. No remedy or election hereunder shall be deemed
exclusive, but shall wherever possible, be cumulative with all other remedies at
law or in equity.

by Tenant shall be deemed both a covenant and a condition.

where the Premises are located.

      16.14 SUBORDINATION.

            (a) This Lease, at Landlord's option, shall be subordinate to any
ground lease, mortgage, deed of trust, or any other hypothecation for security
now or hereafter placed upon the real property of which the 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, Tenant's right to quiet possession of the
Premises shall not be disturbed if Tenant is not in default and so long as
Tenant 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 Tenant, 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.

            (b) Tenant agrees to execute any documents required to effectuate
such subordination or to make this Lease prior to the lien of any mortgage, deed
of trust or ground lease, as the case may be and failing to do so within ten

Landlord may at anytime place on or about the premises any ordinary "For Sale"
signs and Landlord may at any time during the last one hundred twenty (120) days

or conduct any auction thereon without Landlord's prior written consent.

      16.18 MERGER. The voluntary or other surrender of this Lease by Tenant, or
a mutual cancellation thereof, shall not work a merger, and shall, at the option
of Landlord, terminate all or any existing subtenancies or may, at the option of
Landlord, operate as an assignment to Landlord of any or all of such
subtenancies.

      16.19 CORPORATE AUTHORITY. If Tenant is a corporation, each individual
executing this Lease on behalf of said corporation represents and warrants that
he is duly authorized to execute and deliver this Lease on behalf of

hereby waive all rights to proceed against any of the partners, or the officers,
shareholders, or directors of any corporate partner of Landlord except to the
extent of their interest in the partnership. The term "Landlord", as used in
this Article, shall mean only the owner or owners at the time in question of the
fee title or its interest in a ground lease of the Premises, and in the event of
any transfer of such title or interest, Landlord herein named (and in case of
any subsequent transfers the then grantor) shall be relieved from and after the
date of such transfer of all liability as respects Landlord's obligations
thereafter to be performed, provided that any funds in the hands of Landlord or
the then grantor at the time of such transfer, in which Tenant has an interest,
shall be delivered to the grantee. The obligations contained in this Lease to be
performed by Landlord shall, subject as aforesaid, be binding on Landlord's
successors and assigns, only during their respective periods of ownership.

17.   PERFORMANCE BOND. At any time Tenant either desires to or is required to
make any repairs, alterations, additions, improvements or utility installation
thereon, pursuant to Articles 7.5 or 9.2 herein, or otherwise, Landlord may at
his sole option require Tenant, at Tenant's sole cost and expense, to obtain and
provide to Landlord a lien and completion bond in an amount equal to one and
one-half (11 1/2) times the estimated cost of such improvements, to insure

                                    RECITALS:

      A. The Company is engaged in the business of developing software designed

agrees to sell, convey, assign, transfer, set over and deliver to Buyer, the

reductions thereto, as provided in the Escrow Agreement, to the Stockholders who
held Common Stock or vested Options in accordance with each such Stockholder's
respective pro rata share (based on the total Cash Consideration received by
such Stockholder). On the date that is twenty four (24) months from the Closing
Date (or if such date is not a business day, on the next business day
thereafter), the Escrow Agent will pay the remaining balance of the Escrow
Amount, less the amount of any reductions thereto as provided in the Escrow
Agreement, to the Stockholders who held Common Stock or vested Options in
accordance with each such Stockholder's respective pro rata share (based on the
total Cash Consideration received by such Stockholder). Notwithstanding the
foregoing, in the event there is then a pending claim for Damages by the Buyer
pursuant to the provisions of Section 14 hereof, any required distribution from
the Escrow Amount shall be postponed in accordance with the procedures stated in
the Escrow Agreement pending the resolution of such claim(s) and any related
reduction to the Escrow Amount.

            3.2 The Escrow Amount is subject to payment to Buyer in accordance
with the terms of the Escrow Agreement, and in satisfaction of any claim for
Damages by Buyer pursuant to the provisions of Section 14 hereof except for
liability directly related to a Stockholder's direct participation in fraud as
provided in Section 14.1(b)(ii).

            3.3 Payment of amounts from the Escrow Amount to Buyer pursuant to
this Section 3 and the Escrow Agreement will constitute Buyer's sole remedy with
respect to any claim for Damages and Buyer will not have any claim against a
Stockholder in excess of amounts paid from the Escrow Amount except for
liability directly related to a Stockholder's direct participation in fraud as
provided in Section 14.1(b)(ii). To the extent claims for Damages exceed the
Escrow Amount, Buyer releases each Stockholder from such claims except for
liability directly related to a

                                        2
<PAGE>

Stockholder's direct participation in fraud as provided in Section 14.1(b)(ii).
Buyer acknowledges that it shall not be able to recover any excess amounts from
any of the Stockholders beyond the scope stated in this Section 3.3.

            3.4 Under no circumstances will the Stockholders, without the prior
written consent of the Buyer, assign, transfer or grant any security interest in
the Escrow Amount to any party.

            3.5 Disclaimer; Acknowledgement. Buyer acknowledges that the Company
has been operated as an independent business and that no Stockholder, other than
the Stockholders named in Section 6.22 hereof, has supervised the Company's
day-to-day operations. Therefore, such Stockholders are not in control of the
representations and warranties made in Section 6 hereof and are making such
representations and warranties only as to their knowledge. Notwithstanding the
foregoing, such Stockholders acknowledge that, insofar as their indemnification
obligations under Section 14 hereof are made jointly and severally and because
the Stockholders named in Section 6.22 are making such representations and
warranties without qualification as to their knowledge (other than as expressly
stated in the subsections of Section 6), such Stockholders shall be jointly and
severally liable for Damages (as defined in Section 14.2 hereof) resulting from
a breach of such representations and warranties (except to the extent expressly
specified otherwise in Sections 6.7, 6.15 and 6.18), even if such Stockholders
themselves, as a result of their lack of knowledge or otherwise, are not
directly in breach thereof. In addition, such Stockholders shall be severally
liable for any breach of the representations and warranties in Section 5,
without any qualification as to their knowledge other than as expressly stated
in the subsections of Section 5. The Stockholders and Buyer further acknowledge
that liability for any breach of the representations and warranties under
Section 5 or Section 6 shall be limited to the Escrow Amount in all cases other
than in the case of a liability directly related to a Stockholders' direct
participation in fraud, as provided in Section 14.1(b)(ii), in which case the
liability will be several to the Stockholder participating in the fraud and will
be unlimited as to amount or duration.

      4. Equity Representative. Each of the Stockholders (and their successors
and assigns) hereby irrevocably consents to the appointment of, and does hereby
appoint and empower, W. Gary Suttle, the President of Rockford Corporation (and
W. Gary Suttle does hereby accept such appointment), as the sole and exclusive
representative of the Stockholders (the "Equity Representative") with respect to
all matters pertaining to this Agreement, as well as the Escrow Agreement
(including the execution thereof). The Equity Representative will serve until
replaced by the Stockholders, as evidenced in a writing executed by one or more
Stockholders holding a majority of the Company's Common Stock (on a
fully-diluted basis) immediately prior to the Closing Date. Buyer is entitled to
rely upon the decisions of the Equity Representative until given written notice
by a new Equity Representative of the replacement, which notice will be
accompanied by a copy of the writing by which the Stockholders replaced the old
Equity Representative. All decisions of the Equity Representative shall be final
and binding on all of the Stockholders, and the Buyer shall be entitled to rely
upon, without independent investigation, any decision of the Equity
Representative and shall be jointly and severally indemnified by the
Stockholders and held harmless by each Stockholder for any action or inaction
taken or omitted to be taken by Buyer in reliance thereon.

      5. Several Representations and Warranties of the Stockholders.

                                        3

state securities laws. Neither such Stockholder nor any Shares owned by such
Stockholder are or will be a party or subject to any contract, agreement,
commitment, plan or understanding, written or oral, (i) granting any rights or
options in or to such Shares or any interest therein, (ii) relating to voting or
dividend rights or privileges with respect to the Shares, (iii) providing for or
restricting the sale, transfer or assignment of the Shares, or (iv) imposing any
other restrictions on the Shares.

            5.3 No Conflicts. Neither the execution and delivery of this
Agreement by such Stockholder, the performance by such Stockholder of such
Stockholder's obligations hereunder, nor the consummation of the transactions
contemplated hereby, including, but not limited to, the execution by such
Stockholder of an Employment Agreement and/or a Non-Competition Agreement
pursuant to Section 8.7 hereof, as applicable, will result in any of the
following: (a) a default or an event that, with notice or lapse of time, or
both, would constitute a default, breach or violation of any of the terms,
conditions or provisions of any lease, license, franchise, promissory note,
contract, agreement, commitment, indenture, mortgage, deed of trust, or other
instrument, document or arrangement to which such Stockholder is a party or by
which such Stockholder's properties or assets may be bound (a "Stockholder
Contract") and which would, or could reasonably be expected to, have an effect
on such Stockholder's ability to transfer the Shares to Buyer free of Liens; (b)
the creation or imposition of any Lien on any of the Shares; (c) the termination
of any Stockholder Contract which would, or could reasonably be expected to,
have an effect on such Stockholder's ability to transfer the Shares to Buyer; or
(d) a violation or breach of any order, writ, injunction, decree, law, statute
or regulation of any court or governmental authority applicable to such
Stockholder or any of such Stockholder's properties or assets which would, or
could reasonably be expected to, have an effect on such Stockholder's ability to
transfer the Shares to Buyer.

            5.4 No Third Party Consents. No consent, approval, order or
authorization of, or registration, declaration or filing with, any person or
entity or any court, administrative agency or commission or other governmental
authority or instrumentality is required by or with respect to such Stockholder
in connection with the execution and delivery of this Agreement or the
consummation of the transactions contemplated hereby.

            5.5 Absence of Claims. Such Stockholder does not, and at the Closing
will not, have any claim, demand or cause of action against the Company, or any
of its subsidiaries and affiliates and each of their past and current officers,
directors, employees, agents or representatives and knows of no fact, event or
circumstance which could reasonably be expected to result in any such claim.

            5.6 Delegation of Authority to Equity Representative. The delegation
of authority by such Stockholder to the Equity Representative pursuant to this
Agreement, is a valid and enforceable delegation and such Stockholder has the
full power and authority to make such delegation.

            5.7 Disclosure. None of the representations or warranties of such
Stockholder contained in this Section 5 or the related schedules, or in any
certificate furnished or to be furnished pursuant to this Agreement pertaining
to the same, contains any statement of a material fact that was untrue when made
or omits to state any material fact necessary to make the statements of fact
contained herein or therein not misleading in any material respect.

            5.8 Disclosure Schedule. Any exception set forth in any section or
subsection of the Disclosure Schedule furnished hereunder by the Stockholders
shall be deemed to modify only the representations or warranties contained in
the specifically identified sections or subsections of this Section 5 (as the
case may be) to which such sections or subsections of the Disclosure Schedule
specifically relate, unless there is a cross-reference made in any other section
or subsection of the Disclosure Schedule to such exception or such exception
expressly identifies representation and warranties in other sections or
subsections of this Section 5 which it modifies or to which it relates, in which
case such exception shall modify such other representations and warranties as
well.

      6. Representations and Warranties of the Company and Stockholders.

      Except as disclosed in the Disclosure Schedule by reference to the
specific section or subsections to which a disclosure pertains, the Company and
each of the Stockholders (to their knowledge in the case of the Stockholders,
except for Stockholders Lou Hughes and Craig Janik), jointly and severally,
represent and warrant to Buyer as follows:

            6.1 Organization; Authority and Necessary Actions.

                  (a) Organization and Good Standing; Corporate Matters. The
Company is a corporation duly organized, validly existing and in good standing
under the laws of the State of Delaware, and is duly authorized or qualified to
do business as a foreign corporation in each jurisdiction in which the character
of the properties owned by it or the nature of the Business makes such
authorization or qualification necessary and where the failure to be so
authorized or qualified would have a Material Adverse Effect (as hereinafter
defined) on the Company. As used in this Agreement, unless otherwise indicated,
the term "Material Adverse Effect" when used in connection

                                        5
<PAGE>

with the Company, means any event, circumstance, change or effect that is, or
could reasonably be expected to be, materially adverse to the condition
(financial or otherwise), properties, assets, liabilities, businesses,
operations, or results of operations of the Company either prior to or following
the Closing. The Company does not own or control, directly or indirectly, any
interest or investment (whether equity or debt) in any corporation, partnership,
limited liability company, joint venture, association, business organization,
trust or entity. The Company has all necessary corporate power and authority to
conduct the Business as it is now, and has since its organization been,
conducted and to own, lease and/or operate the properties and assets which it
now owns, leases or operates. The Company has delivered to Buyer complete and
accurate copies of (a) the Amended and Restated Certificate of Incorporation of
the Company and all amendments thereto, certified by the Secretary of State of
the State of Delaware, (b) the Bylaws of the Company and all amendments thereto,
duly certified by its corporate secretary, (c) the minute and stock books of the
Company and (d) any agreements, commitments or understandings restricting the
transfer of or otherwise relating to the Shares or any other securities of the
Company to which the Company is a party. Such Amended and Restated Certificate
of Incorporation and Bylaws are in full force and effect and the Company is not
in violation of its Amended and Restated Certificate of Incorporation or Bylaws.
The minute and stock books of the Company are complete and accurate in all
material respects.

                  (b) Authority; Necessary Actions; Binding Effect. The Company
has the full legal right, capacity, power and authority to execute and deliver,
and to perform its obligations under this Agreement and the Escrow Agreement.
The Company has taken all corporate action necessary to authorize its execution
and delivery of, and the performance of its obligations under, this Agreement
and the Escrow Agreement. This Agreement and the Escrow Agreement have each been
duly executed and delivered by the Company and each constitutes a valid
obligation of the Company that is legally binding on and enforceable against the
Company in accordance with its respective terms, except as such enforceability
may be limited by (i) bankruptcy, insolvency, moratorium or other similar laws
affecting creditors' rights, and (ii) general principles of equity relating to
the availability of equitable remedies (regardless of whether such Agreements
are sought to be enforced in a proceeding at law or in equity).

            6.2 Capital Structure of the Company. As of the Closing Date, the
authorized capital stock of the Company will consist solely of 125,000,000

and outstanding. Except for vested options to purchase 25,077,432 shares of
Common Stock and unvested options to purchase 11,260,080 shares of Common Stock
outstanding as of the Closing Date, there are no outstanding subscriptions,
options, calls, warrants, convertible or exchangeable debt or securities,
agreements, arrangements, commitments, understandings or other rights, oral or
written, obligating the Company to offer, sell or issue any additional shares of
its capital stock of any class or any outstanding shares of capital stock of the
Company. The Company is not aware of any voting trust agreement or any other
contract, agreement, commitment, plan or understanding restricting or otherwise
relating to voting or dividend rights or privileges with respect to, or which
either provide for or restrict the sale, transfer or assignment of, the Shares.
All of the outstanding shares of capital stock of the Company are validly
issued, fully paid, nonassessable, and were not issued in violation or
contravention of any federal or applicable state securities laws or regulations,
any preemptive rights (contractual or other) of any person or entity, or any
agreement to which the Company is or was a party. There are no obligations,
contingent or otherwise, of the Company to repurchase, redeem or otherwise
acquire any currently outstanding, or make any payments in respect of any
currently or previously outstanding, shares of capital stock of the Company. The
Company has not repurchased, redeemed or otherwise acquired

                                        6
<PAGE>

any shares of its capital stock or declared, paid or set aside funds for the
payment of any dividend or other distribution on its shares of capital stock, or
effected any recapitalization, reclassification, combination, stock split or
other transaction affecting its authorized or outstanding shares of capital
stock.

            6.3 No Conflicts. Neither the execution and delivery of this
Agreement or the Escrow Agreement by the Company or any Stockholder (as
applicable), the performance by the Company or any Stockholder of their
respective obligations thereunder (as applicable), the execution and delivery by
the Company or any Stockholder of any other agreement required to be entered
into pursuant to this Agreement, nor the consummation of any of the transactions
contemplated hereby or thereby, will result in any of the following: (a) a
default or an event that, with notice or lapse of time, or both, would
constitute a default, breach or violation of (i) any provision of the Amended
and Restated Certificate of Incorporation or Bylaws of the Company, or (ii) any
of the terms, conditions or provisions of any lease, license, franchise,
promissory note, contract, agreement, commitment, indenture, mortgage, deed of
trust, or other instrument, document or arrangement to which the Company is a
party or by which it or any of its respective properties or assets may be bound
and which is material to the Company (a "Company Contract"); (b) the creation or
imposition of any Lien on any of the assets or properties of the Company; (c)
the termination of any Company Contract or the acceleration of the maturity of
any indebtedness or other material obligation of the Company; (d) a violation or
breach of any order, writ, injunction, decree, law, statute or regulation of any
court or governmental authority applicable to the Company or any of its
respective properties or assets; (e) the cessation or termination of any other
business relationship or arrangement between the Company and any third party the
cessation or termination of which would have a Material Adverse Effect; (f) any
material adverse effect on the Intangible Personal Property (as defined in
Section 6.7(b) hereof) or on the Company's rights or ability to use the
Intangible Personal Property or on the Company's rights or privileges under the
license agreements or other arrangements, if any, listed on Section 6.7(b) of
the Disclosure Schedule.

            6.4 Consents and Approvals. No consent, approval, order or
authorization of, or registration, declaration or filing with, any person or
entity or any court, administrative agency or commission or other governmental
authority or instrumentality is required by or with respect to the Company in
connection with the execution and delivery of this Agreement or the consummation
of the transactions contemplated hereby, except for (i) any applicable
requirements under federal or state securities laws, (ii) any filings required
by the Nasdaq Stock Market, Inc., and (iii) where failure to obtain such
consents, approvals, orders or authorizations, or to make such filings or
notifications could not reasonably be expected to (A) have, individually or in
the aggregate, a material adverse effect on the Company, or (B) prevent or delay
materially the consummation of the transactions contemplated by this Agreement.

            6.5 Financial Statements. The Company has delivered to Buyer
complete and accurate copies of the unaudited financial statements of the
Company for the period from January 1, 2004 to May 31, 2004 and for each of the

obligations or commitments of any nature, secured or unsecured and whether due
or to become due, absolute, contingent or otherwise, which, in accordance with

            6.7 Property of the Company. The Company owns or otherwise has the

performance of any Company Contract or the conduct of the Business as now
conducted in the ordinary course and consistent with past practices and as

with past practices.

                  (a) Tangible Personal Property. Section 6.7(a) of the
Disclosure Schedule contains a complete and accurate listing of all machinery,
implements, supplies, equipment, computers, furniture, fixtures, vehicles,

listing constitute all the tangible personal property reasonably necessary for
the conduct by the Company of the Business, and such assets are in good
operating condition and repair, ordinary wear and tear excepted, and have been
properly maintained. Except as disclosed in Section 6.7(a) of the Disclosure
Schedule, no personal property used by the Company in connection with the
Business is held under any lease, security agreement, conditional sales

hardware and other trade secrets and know-how (the "Intangible Personal
Property") owned by the Company or used in or necessary to the conduct of the
Business. The Company's rights in such Intangible Personal Property are valid
and enforceable, and neither the Company nor any Stockholder is aware of any
third party that is, or that has been, infringing or misappropriating any such
Intangible Personal Property. Section 6.7(b) of the Disclosure Schedule also
contains a list of all license agreements and other arrangements under which the
Company uses, or licenses to any third party, any patents, trademarks or other
intellectual property, complete and accurate copies of which have been provided
to Buyer. The Company owns or is licensed, or otherwise has the full right and
authority to use, all Intangible Personal Property required for the conduct of
the Business in the manner presently conducted, and such use does not conflict
with, infringe upon or violate any trademark, trade name, copyright, patent
rights or trade secret rights of any other person or entity. Neither the Company
nor any of its products or advertising or marketing materials, (i) has
infringed, or is now infringing, any patent, trade name, trademark, service
mark, copyright, trade secret, technology, know-how or process belonging to any

                                        9
<PAGE>

other person, firm or corporation, which infringement would have a Material
Adverse Effect on the Company or (ii) has breached or violated or is in breach
or violation of any license agreement governing the use of any intellectual
property by the Company which, in either case, breach or violation could
reasonably be expected to have or result in a Material Adverse Effect on the
Company. The Company has not received any written notice or other indication of
any such claim of infringement or violation. Each Stockholder hereby severally
represents (without any joint liability for the same several representation of
the other Stockholders) that such Stockholder has not received any written
notice or other indication of any such claim of infringement or violation.
Except as set forth in Section 6.7(b) of the Disclosure Schedule, each present
or former employee or consultant of the Company has executed an agreement with
the Company which provides for valid and enforceable assignments to the Company
of any and all rights or claims in any intellectual property rights that any
such employee or consultant has or may have by reason of any contribution,
participation or other role in the development, conception, creation, reduction
to practice or authorship of any invention, innovation, development or work of
authorship or any other intellectual property that is used or intended for use
in the Business.

                  (c) Real Property. Section 6.7(c) of the Disclosure Schedule

by, leased to or used in any way by the Company (the "Real Properties"),
together with a brief description of the structures thereon and the uses being
made thereof, and a list of all leases under which the Company possesses or uses
real property (the "Real Property Leases"). True and correct copies of the Real
Property Leases, and any and all amendments thereto, have been delivered to
Buyer. Each of the Real Property Leases is valid, binding and enforceable in
accordance with its terms, and is in full force and effect. The Company is not
in material default, and no event has occurred which, with the giving of notice
or lapse of time or both, would constitute a material default under, or which
would entitle the lessor to terminate, any of such Real Property Leases. The
Company has also delivered to Buyer complete and accurate copies of any and all
title insurance policies or commitments and environmental studies or reports in
the possession or control of the Company with respect to any of the Real
Properties, which policies, commitments and studies are listed on Section 6.7(c)
of the Disclosure Schedule. The zoning of each parcel of Real Property permits
the presently existing improvements and structures and the continuation of the
Business presently conducted thereon. No changes in such zoning are pending or
threatened, and no condemnation or similar proceedings are pending against any
such parcel of real property.

                  (d) Title. The Company has good, valid and marketable title
to, or a valid leasehold interest in, all of the assets and properties
(personal, real, mixed, tangible or intangible) which it purports to own or
lease, free and clear of any and all Liens other than Permitted Liens. As used
in this Agreement, the term "Permitted Liens" shall mean (i) mechanics',
carriers', workmen's, repairmen's or other similar Liens arising or incurred in
the ordinary course of business in respect of obligations which are not overdue,
or which are being contested in good faith; (ii) such Liens and minor
imperfections of title, if any, as are not material in amount, do not materially
detract from the value or impair the use of any material assets subject thereto
or the operations of the Business by the Company and have arisen only in the
ordinary course of business; and (iii) Liens for current Taxes (as hereinafter
defined) not yet due or for Taxes being contested in good faith by appropriate
proceedings and for which adequate reserves have been set aside.

                  (e) Accounts Receivable. The Company has delivered to Buyer a
complete and current aging of all accounts receivable of the Company as of July
31, 2004, as set

                                       10
<PAGE>

forth on Section 6.7(e) of the Disclosure Schedule. All such accounts receivable
represent, and all accounts receivable arising from the operation of the
business of the Company between the date hereof and the Closing (collectively,
the "Accounts Receivable") will represent, amounts due the Company for bona fide
sales of products actually made or services actually performed on or prior to
the date such Accounts Receivable were or will be recorded on the books of the
Company, in the ordinary course of the Business and consistent with past
practices, and are, or on or prior to the Closing Date will be, valid and
collectible in full in the ordinary course of business. Except for reserves
shown on the Financial Statements, no reserves for invalid or uncollectible
receivables have been made, and no reserves are necessary in excess of those
shown on the Financial Statements. There is no contest, claim or right of
set-off contained in any oral or written agreement with any account debtor
relating to the amount or validity of any Account Receivable.

                  (f) Inventories. The Company has furnished to Buyer a complete
and accurate list of all inventories, including packaging materials, components,
supplies, raw materials, work-in-process and finished goods, of the Company as
of July 31, 2004 (the "Inventories"), as set forth in Section 6.7(f) of the
Disclosure Schedule. The Inventories are, and as of the Closing Date will be, of
a quality and quantity usable and salable in the ordinary course of business,
except for items of obsolete, damaged or slow moving materials and materials of
below standard quality, all of which have been written off or written down to
net realizable value and, in the aggregate, are not material in amount.

            6.8 Contracts and Agreements. Except as described in Section 6.8 of
the Disclosure Schedule, the Company is not a party to, and none of its assets
and properties are subject to: (a) any employment contract with any officer,
consultant, director or employee or any affiliate of the foregoing; (b) any
lease of real or personal property; (c) any agreement or understanding, written
or oral, that provides for or relates to the purchase, sale or other disposition
of any property, materials, equipment or supplies (except purchase or sales
orders from or to individual customers or individual suppliers incurred in the
ordinary course of business and consistent with past practices); (d) any
instrument creating or providing for the creation of any Lien on any of the
assets or properties of the Company or evidencing or relating to indebtedness
constituting notes payable or long-term debt; (e) any other Company Contract,
which shall include, without limitation, any contracts or agreements relating
to, or entered into by the Company in connection with, the purchase or sale of
any business or product line; or (f) any other agreement, contract, lease,
license, franchise, promissory note, indenture, mortgage, deed of trust or other
instrument, document, arrangement, commitment or understanding which relates to
and which is material to the Business. There has been delivered to Buyer (i)
complete and accurate copies of each written contract or agreement listed on
Section 6.8 of the Disclosure Schedule, and any and all amendments thereto, and
(ii) an accurate written summary of the terms of any oral agreement or
understanding that the Company may have with any other person or entity that is
material to the Company or the Business, which shall include, without
limitation, any oral agreement or understanding that the Company may have with
any of the customers or suppliers listed on Section 6.10 of the Disclosure
Schedule, and any amendments thereto. Each of such contracts, agreements,
licenses and instruments so listed, or required to be so listed, or described or
required to be described in a written summary required to be delivered pursuant
hereto, is a valid and binding obligation of the Company and of the other
parties thereto, and is enforceable in accordance with its terms, except as
enforceability may be affected by bankruptcy, insolvency, moratorium or similar
laws affecting creditors' rights generally and general principles of equity
relating to the availability of equitable remedies. There have not been any
defaults by the Company or any defaults or claims of default or of
non-enforceability by the other

                                       11
<PAGE>

party or parties to such contracts, agreements, licenses and instruments which,
individually or in the aggregate, would have a Material Adverse Effect on the
Company or the Business and there are no facts, events or conditions that have
occurred which, through the passage of time or the giving of notice, or both,
would constitute a default by the Company or by the other party or parties under
any of such contracts, agreements, licenses and instruments that could
reasonably be expected to have a Material Adverse Effect on the Company or the
Business or that would create or result in the imposition of a Lien on any
material assets or properties of the Company.

            6.9 Employees; Labor Matters and Employee Plans.

                  (a) Section 6.9 of the Disclosure Schedule contains complete
and accurate lists of each director and officer of the Company and of all
employees of the Company, which lists include the job position(s) of and
compensation and benefits payable to each of such individuals as a result of his
or her employment by or association with the Company. Section 6.9 of the
Disclosure Schedule also contains a list of consultants and any other
independent contractors that have provided professional or other services to the
Company and have received or are expected to receive fees or other compensation
from the Company at or in excess of $50,000 per annum. The Company has furnished
to Buyer a complete and accurate copy of its employee handbook (if one exists)
and a written description of all material employment or personnel policies of
the Company not set forth therein.

                  (b) The Company is not a party to or otherwise bound by or
subject to any collective bargaining or other labor, employment, deferred
compensation, bonus, retainer, consulting, or incentive agreement, plan or
contract. There has been no strike or other work stoppage by, nor does Company
know of, any union organizing activity among any of the employees of the
Company. The Company is in compliance, in all material respects, with all
applicable laws respecting employment and employment practices, terms and
conditions of employment and wages and hours, and is not engaged in any unfair
labor practice. There is no unfair labor practice complaint pending or, to the
knowledge of Company, threatened against the Company, nor is there any factual
basis for any such complaint.

                  (c) Section 6.9 of the Disclosure Schedule also contains a
complete, current and correct list of all Employee Plans (as hereinafter
defined) of the Company (complete and accurate copies of which have been
delivered to Buyer). For purposes of this Agreement, the term "Employee Plan"
includes all present plans, programs, agreements or any other arrangements
(including all amendments to and components of the same, such as a trust with
respect to a plan) providing any remuneration or benefits, other than current
cash compensation, to any current or former employee of the Company or to any
other person who provides, or at any time since January 1, 2004, provided,
services to the Company, whether or not such plans, programs, agreements or any
such other arrangements, are subject to the Employee Retirement Income Security
Act of 1974, as amended ("ERISA"), or are qualified under the Internal Revenue
Code of 1986 (as amended, the "Code"). By way of example, but without limiting
the generality of the foregoing, the term Employee Plan includes, but is not
limited to, employee benefit plans (as defined in Section 3(3) of ERISA),
pension, retirement, profit sharing, stock option, stock bonus, and
non-qualified deferred compensation plans, any multiemployer plan (as defined in
Section 3(37) of ERISA), disability, medical, dental, health insurance, life
insurance, incentive compensation, vacation benefit, and fringe benefit plans,
programs or arrangements. Any and all tax returns, reports, forms or other
documents required to be filed by the Company under applicable federal, state or
local law with respect to the

                                       12
<PAGE>

Employee Plans have been timely filed and are correct and complete in all
material respects; and any and all amounts due by the Company to any
governmental agency or entity with respect to the Employee Plans have been
timely and fully paid. The Company has not terminated any Employee Plan.

                  (d) All Employee Plans are now, and have always been,
established, maintained and operated in accordance, in all material respects,
with all applicable laws (including, but not limited to, ERISA and the Code) and
all regulations and interpretations thereunder and in accordance with their plan
documents. All communications with respect to each Employee Plan by any members
of any plan committee, plan fiduciaries, plan administrators, the Company or its
Board of Directors or employees, accurately reflect the documents and operations
of each such Employee Plan in all material respects. The Internal Revenue
Service has issued one or more determination letters with respect to each funded
Employee Plan stating that, from the inception of each such Employee Plan, such
Employee Plan has been and is qualified under Section 401 of the Code and each
trust maintained in connection with each such Employee Plan has been and is
exempt under Section 501 of the Code. No Employee Plan is a multiemployer plan
within the meaning of the Code or ERISA, a defined benefit plan within the
meaning of Section 3(35) of ERISA, a plan subject to Section 302 of ERISA or
Section 412 of the Code, or funded through a welfare benefit fund (as defined in
Section 419 of the Code). The Company has not participated in, maintained,
contributed to or been required to contribute to any employee benefit plan
subject to Title IV of ERISA or any retiree medical or retiree life insurance
benefit plan. All contributions required to be made to or with respect to each
Employee Plan and all costs of administering each Employee Plan have been
completely and timely paid. All reports, forms and other documents required to
be filed with any governmental entity with respect to any Employee Plan have
been timely filed and are accurate. There is and there has been no actual or, to
the knowledge of the Company, no threatened or expected litigation or
arbitration concerning or involving any Employee Plan. No complaints to or by
any government entity have been filed or, to the knowledge of the Company, have
been threatened or are expected with respect to any Employee Plan. No Employee
Plan or any other person has any liability to any plan participant, beneficiary
or other person under any provision of ERISA, the Code or any other applicable
law by reason of any action or failure to act in connection with any Employee
Plan. There has been no breach of fiduciary duty or non-exempt prohibited
transaction as described in Section 406 of ERISA and Section 4975 of the Code
with respect to any Employee Plan. No Employee Plan provides medical benefits to
one or more former employees (including retirees), other than benefits required
to be provided under Section 4980B of the Code or Sections 601 to 608 of ERISA.
Each welfare benefit plan (as defined in Section 3(2) of ERISA) is, and has
been, in material compliance with the requirements of Code Section 4980B and
Sections 601 to 608 of ERISA. There is no contract, agreement or benefit
arrangement covering any employee of the Company which individually or
collectively would constitute an "excess parachute payment" under Section 280G
of the Code.

                  (e) The consummation of the transactions contemplated by this
Agreement will not (i) entitle any individual to severance pay, or (ii)
accelerate the time of payment or vesting, or increase the amount, of
compensation that, but for such transactions, would be due to any individual.
The Company has delivered to the Buyer complete and accurate copies of each
plan, agreement or arrangement relating to the foregoing, including all
amendments thereto.

                  (f) With respect to any insurance policy providing funding for
benefits under any Employee Plan, (i) there is no material liability of the
Company in the nature of a

                                       13
<PAGE>

retroactive or retrospective rate adjustment, loss sharing arrangement, or other
actual or contingent liability, nor would there be any such material liability
if such insurance policy was terminated on the date hereof, and (ii) to the
knowledge of the Company, no insurance company issuing any such policy is in
receivership, conservatorship, liquidation or similar proceeding and the Company
has not received any notice that any such proceeding with respect to any such
insurance company is pending or imminent.

            6.10 Customers and Suppliers. Section 6.10 of the Disclosure
Schedule contains complete and accurate lists of (a) each customer or client of
the Company, including original equipment manufacturers ("OEMs"), who accounted
for more than five percent (5%) of the sales of the Company in either of the two
most recent fiscal years, showing the approximate aggregate dollar amount of
sales to each such customer during each of such fiscal years; and (b) the ten
(10) largest suppliers of the Company in terms of purchases during each of the
two most recent fiscal years, showing the approximate aggregate dollar amounts
of purchases by the Company from each such supplier during each of such fiscal
years. There has been no change in the business relationship of the Company with
any customer or supplier named in Section 6.10 of the Disclosure Schedule which
has had or could reasonably be expected to have a Material Adverse Effect on the
Company or the Business. The Company does not have any present information that,
and is not aware that, due to any events or circumstances that have occurred
prior to the date of this Agreement, any of the customers or suppliers listed in
Section 6.10 of the Disclosure Schedule intends to cease doing business with the
Company, or alter materially the amount of the business that any of them is
presently doing with the Company, or will require, as a condition of continuing
to purchase products from or to sell raw materials or components to the Company,
a change in the prices at or in any other material terms under which it has been
doing business with the Company.

            6.11 Product Warranties and Liabilities. Section 6.11 of the
Disclosure Schedule sets forth the product return policies (the "Return
Policies") of, and all Warranties (as hereinafter defined) given or made by, the
Company. "Warranties" shall mean all service, repair, replacement and other
obligations based upon or arising out of express and implied warranties made or
deemed made in connection with the sale of goods or the performance of services
by the Company. The Company has not extended or granted any return rights or
given or made any warranties with respect to any products sold or services
performed by it, other than Warranties and per Return Policies in the ordinary
course of business. None of the customers of the Company has claimed to the
Company or, to the Company's knowledge, to the Company's suppliers, that the
Company's products are defective. The Company does not have any knowledge of any
products which have been shipped by the Company in a condition that such
products might reasonably be expected to be returned by the customer, or of any
intention on the part of any customer to return any of the Company's products,
except returns by customers in the ordinary course of business and consistent
with the Return Policies and which, in any event, are not expected to be
material in amount. The Company does not have any knowledge of any fact or of
the occurrence of any event forming the basis of any present or future claim
against the Company, whether or not fully covered by insurance, for liability on
account of negligence or product liability or on account of any Warranties which
would have, individually or in the aggregate, a Material Adverse Effect on the
Company or the Business. Adequate reserves have been set aside in the Financial
Statements for Warranty claims and product returns.

            6.12 Licenses and Permits; Compliance With Laws. Section 6.12 of the
Disclosure Schedule contains a complete and accurate list of all governmental
licenses, permits, franchises, authorizations, certificates, rights, privileges
and registrations held by or issued to the

                                       14
<PAGE>

Company which are required for the lawful conduct of its business and which the
failure to maintain could have a Material Adverse Effect (the "Licenses and
Permits"). Each of the Licenses and Permits is in full force and effect, and
there are no pending or, to the knowledge of the Company, threatened claims or
proceedings challenging the validity of, or seeking to revoke or discontinue,
any of the Licenses and Permits. None of the transactions contemplated by this
Agreement will affect the validity of or cause the revocation or discontinuation
of any of the Licenses and Permits. The Business is being, and has been,
conducted in compliance with all applicable federal, state, local and
international laws, statutes, ordinances, rules, regulations, orders, decrees
and other requirements of all governmental authorities and other political
subdivisions and agencies thereof having jurisdiction over the Company,
including, without limitation, all such laws, regulations, ordinances and
requirements relating to environmental matters, antitrust, consumer protection,
labor and employment, zoning and land use, immigration, health and occupational
safety matters, except where any instances of noncompliance, either individually
or in the aggregate, have not had, and could not reasonably be expected to have,
any Material Adverse Effect on the Company or the Business.

            6.13 Environmental and Safety Matters. The Company and the use of
its respective properties and assets and the operation of the Business have
complied and are in compliance in all material respects with all federal, state,
local and regional statutes, laws, ordinances, rules, regulations and orders
relating to the protection of human health and safety, natural resources or the
environment, including, but not limited to, air pollution, water pollution,
noise control, on-site or off-site hazardous substance discharge, disposal or
recovery, toxic or hazardous substances, training, information and warning
provisions relating to toxic or hazardous substances, or employee safety, and no
notice of violation of any such statutes, laws, ordinances, rules, regulations
and orders with respect thereto and no notice of the violation, cancellation or
revocation of any permit, license or other authorization relating thereto, has
been received, nor is any such notice pending or, to the knowledge of the
Company, threatened. No underground or above-ground storage tanks or surface
impoundments are located on any of the Real Properties. There has been no
generation, use, treatment, storage, transfer, disposal, release or threatened
release, in, at, under, or on any of the Real Properties of toxic or hazardous
substances during the ownership or occupancy thereof by the Company, or, to the
knowledge of the Company, prior to such ownership or occupancy, except in
compliance with applicable statutes, laws, ordinances, rules, regulations,
orders, licenses and permits. There are not now, and at Closing there will not
be, any toxic or hazardous substances on, in or under any of the Real Properties
except in compliance with all applicable laws, regulations, ordinances and
permits relating to environmental protection or the protection of health and
safety. The Company has not received any notice or claim to the effect and the
Company does not know of any basis for a claim to the effect, that the Company
is or may be or become liable to any governmental authority or private party as
a result of the release, or threatened release, of any toxic or hazardous
substances in connection with the operations of the Company, or any of the
predecessors of the Company. None of such operations is the subject of any
actual, or to the Company's knowledge, threatened federal, state or local
investigation evaluating whether any remedial action is needed to respond to a
release or a threatened release of any toxic or hazardous substances at any of
the Real Properties or any other real properties that have been owned, used or
leased by the Company or predecessors thereof. For the purposes of this Section
6.13, "toxic or hazardous substances" shall include any material, substance or
waste that, because of its quantity, concentration or physical or chemical
characteristics, is at any time deemed under any federal, state, local or
regional statute, law, ordinance, regulation or order, or by any governmental
agency pursuant thereto, to pose a present or potential hazard to human health
or safety or the environment, including, but not limited to, (i) any material,
waste or substance which is defined as a "hazardous substance"

                                       15
<PAGE>

pursuant to the Comprehensive Environmental Response, Compensation, and
Liability Act of 1980 (42 U.S.C. 9601 et seq.), as amended from time to time
("CERCLA"), and its related state and local counterparts; (ii) asbestos and
asbestos containing materials and polychlorinated biphenyls; and (iii) any
petroleum hydrocarbon, including oil, gasoline (refined and unrefined) and their
respective constituents and any wastes associated therewith.

            6.14 Insurance Coverage. Section 6.14 of the Disclosure Schedule
contains a list and description of each policy of fire, general liability,
product liability, worker's compensation and other forms of insurance maintained
by the Company. Complete and accurate copies of each such policy have been
delivered to Buyer. All such policies are, and since January 1, 2004, such
policies (or policies substantially equivalent thereto) have been, continuously
in full force and effect and without any gaps in coverage, all premiums with
respect thereto covering all periods up to and including the date hereof have
been paid, and no notice of cancellation, termination or denial of coverage has
been received with respect to any such policy. Such policies (i) are valid,
outstanding and enforceable policies, (ii) provide adequate insurance coverage
for the properties, assets and operations of the Company as presently conducted,
(iii) will remain in full force and effect through the respective dates set
forth on Section 6.14 of the Disclosure Schedule, without the payment of
additional premiums, and (iv) will not in any way be affected by, or terminate
or lapse by reason of, the transactions contemplated by this Agreement. There
has also been furnished to Buyer a schedule that describes all claims of the
Company which are pending under such insurance policies or have been paid to or
on behalf of the Company since January 1, 2004. Since January 1, 2004, the
Company has not been refused any insurance with respect to its properties,
assets or operations, nor has its coverage been limited, by any insurance
carrier to which it has applied for any such insurance or with which it has
carried insurance.

            6.15 Litigation. There is no pending or, to the knowledge of the
Company, threatened, action, suit, arbitration proceeding, charge, complaint,
allegation, investigation, inquiry or other proceeding or claim before any court
or governmental or administrative body or agency or other entity against,
relating to or affecting the Company or any director, stockholder, officer,
agent or employee of the Company in its, his or her capacity as such, or the
assets, properties or Business of the Company or the transactions contemplated
by this Agreement (collectively, "Proceedings"), nor is the Company aware of any
facts or circumstances which could reasonably lead to or provide the basis for
any Proceedings that, if brought or adversely determined against the Company,
could reasonably be expected to have a Material Adverse Effect. Each Stockholder
severally represents (without any joint liability for the same several
representation of the other Stockholders) that such Stockholder is not aware of
any actual or threatened Proceedings that, if brought or adversely determined
against the Company, could reasonably be expected to have a Material Adverse
Effect. There is not in effect any order, judgment or decree of any court or
governmental or administrative body or agency enjoining, barring, suspending,
prohibiting or otherwise limiting the Company, or any officer, director,
employee or agent of the Company, in its capacity as such, from conducting or
engaging in any aspect of the Business, or requiring the Company, or any
officer, director, employee or agent of the Company to take or refrain from
taking any action with respect to any aspect of the Business which could
reasonably be anticipated to have a Material Adverse Effect on the Company or
the Business.

            6.16 Taxes and Tax Returns.

                  (a) The Company has duly and timely filed all Tax Returns (as
hereinafter defined) which are required by law to be filed by it and has duly
and timely paid all Taxes (as hereafter defined) due or claimed to be due from
it (whether or not shown on any Tax Return), and there are no assessments or
claims for payment of Taxes now pending or, to the knowledge of the Company,
threatened, or any audit of the records of the Company being made or threatened
by, any taxing authority. Each Tax Return previously filed is, or to be filed in
the future relating to any period up to the Closing Date shall be, correct and
complete in all respects. The Company is not currently the beneficiary of any
extension of time within which to file any Tax Return. The amounts set up as
provisions for Taxes, if any, on the balance sheets of the Company included in
the Financial Statements are sufficient for the payment of all unpaid Taxes
accrued for or applicable to the periods ended on such dates and all years and
periods prior thereto and for which the Company, at those dates, may have been
liable. The Company has properly withheld and paid, or accrued for payment, when
due, to appropriate state and/or federal authorities, all sales and use taxes,
if any, and all amounts required to be withheld from payments made to its
employees, independent contractors, creditors, stockholders, or other third
parties and has also paid all employment taxes as required under applicable
laws. The Company has not agreed to or is required to make any adjustment under
Code Section 481(a) by reason of a change in accounting method. There is no
income reportable by the Company for a period ending after the Closing Date
attributable to a transaction or other event (e.g., an installment sale)
occurring prior to the Closing Date involving in excess of $25,000. The Company
is not (nor has been) a "reporting corporation" subject to the information
reporting and record maintenance requirements of Code Section 6038A and the
regulations thereunder. The Company does not own any interest in real property
located in any state or local taxing jurisdiction that imposes a tax on the
transfer of such an interest that could apply with respect to the transactions
contemplated by this Agreement.

                  (b) The Company has not waived any statute of limitation in
respect of any taxes or assessments by any federal, state, county, local,
foreign or other taxing jurisdiction or agreed to any extension of time with
respect to an assessment or deficiency in any Tax, and has not been audited by
any taxing authority. The Company has not filed a consent under Section 341(f)
of the Code concerning collapsible corporations.

                  (c) The Company has not made any payments, nor is the Company
a party to any agreement that under any circumstances could obligate it to make
any payments, that would not be deductible under Section 280G of the Code. The
Company has not been a United States real property holding corporation within
the meaning of Section 897(c)(2) of the Code during the applicable period
specified in Section 897(c)(1)(A)(ii) of the Code. The Company is not a party to
any tax allocation or tax sharing agreement and does not have any obligations
under any such agreement to which it may, in the past, have been a party.

                  (d) The Company (i) is not and never has been required to file
a consolidated or combined state or federal income Tax Return with any other
person or entity, and (ii) is not liable for the Taxes of any person under
Treas. Reg. 1.1502-6 (or any similar provision of state, local, or foreign law),
as a transferee or successor, by contract or otherwise.

means any federal, state, local, or foreign income, gross receipts, license,
payroll, employment, excise,

property, personal property, sales, use, transfer, registration, value added,
alternative or add-on minimum, estimated, or other tax of any kind whatsoever,
including any interest, penalty, or addition thereto, whether disputed or not.

                  (f) For purposes of this Agreement, the term "Tax Return"
means any return, declaration, report, claim for refund, or information return
or statement (including, but not limited to, information returns or reports
related to back-up withholding and any payments to third parties) relating to
Taxes, including any schedule or attachment thereto, and including any amendment
thereof.

                  (g) The Company has furnished to Buyer complete and accurate
copies of (A) relevant portions of income tax audit reports, statements of
deficiencies, closing or other agreements received by or on behalf of the
Company relating to Taxes for all open years, and (B) all federal, state, local
and foreign tax returns for all open years.

                  (h) The Company has disclosed on its federal and state income
tax returns all positions taken therein that could give rise to a substantial
understatement penalty within the meaning of Code Section 6662 or corresponding
provisions of state tax law. There are no requests for rulings with respect to
any Tax or potential Tax of the Company pending before any taxing authority.

            6.17 Related Party Transactions. Except as described on Section 6.17
of the Disclosure Schedule, no officer, director, stockholder, option holder or
employee of the Company, and none of their relatives or affiliates, owns any
interest in any competitor, lessor, lessee or customer or supplier of the
Company. The Company is not a party to any transaction or arrangement with any

            7.1 Organization and Good Standing. Buyer is a corporation duly
organized, validly existing and in good standing under the laws of the State of
Delaware. Buyer is duly qualified to do business and is in good standing as a
foreign corporation in each jurisdiction where such qualification is necessary
under applicable law as a result of the conduct of its business and where the
failure to be so qualified would have a material adverse effect on Buyer. Buyer
has the requisite corporate power and authority to carry on its business as now
being conducted and to execute and deliver and perform its obligations under
this Agreement and the Escrow Agreement.

            7.2 Necessary Actions; Binding Effect. Buyer has taken all corporate
action necessary to authorize its execution and delivery of, and the performance
of its obligations under, this Agreement and the Escrow Agreement. This
Agreement and the Escrow Agreement each constitute the valid obligation of Buyer

respective terms, except as such enforceability may be limited by (i)
bankruptcy, insolvency, moratorium or other similar laws affecting creditors'
rights, and (ii) general principles of equity relating to the availability of
equitable remedies (regardless of whether such Agreements are sought to be
enforced in a proceeding at law or in equity).

            7.3 No Conflicts. Neither the execution and delivery of this
Agreement or the Escrow Agreement by Buyer nor the performance by Buyer of its
obligations thereunder nor the consummation of the transactions contemplated
thereby, will result in any of the following: (a) a default or an event that,
with notice or lapse of time, or both, would constitute a default, breach or
violation of (i) any provision of the Amended and Restated Certificate of
Incorporation, as amended, or Bylaws of Buyer, or (ii) any lease, license,
franchise, promissory note, contract, agreement, commitment, indenture,
mortgage, deed of trust, security or pledge agreement, or other agreement,
instrument or arrangement to which Buyer is a party and which is material to
Buyer, considered together with all of Buyer's subsidiaries as a whole (a "Buyer
Contract"); (b) the termination of any Buyer Contract or the acceleration of the
maturity of any indebtedness or other monetary obligation of Buyer that is
material in amount when considered in relation to Buyer and its subsidiaries
taken as a whole; or (c) a violation or breach of any writ, injunction or decree
of any court or governmental instrumentality to which the Buyer is a party or by
which any of its properties is bound or any laws or regulations applicable to
Buyer, where the violation would have a material adverse effect on Buyer
considered together with all of its subsidiaries, as a whole.

            7.4 Brokers and Finders. Except for Global View Advisors, Buyer has
not (i) engaged or authorized any broker, finder, investment banker or other
third party to act on behalf of Buyer, directly or indirectly, as a broker,
finder, investment banker or in any other like capacity in connection with this
Agreement or the transactions contemplated hereby, or (ii) consented to or
acquiesced in anyone so acting. Other than with respect to Global View Advisors,
Buyer does not know of any claim for compensation from any such broker, finder,
investment banker or other third party for so acting or of any basis for such a
claim.

            7.5 Consents and Approvals. No consent, approval, order or
authorization of, or registration, declaration or filing with, any person or
entity or any court, administrative agency or commission or other governmental
authority or instrumentality is required by or with respect to the

                                       20
<PAGE>

Buyer in connection with the execution and delivery of this Agreement or the
consummation of the transactions contemplated hereby, except for (i) any
applicable requirements under federal or state securities laws, (ii) any filings
required by the Nasdaq Stock Market, Inc., and (iii) where failure to obtain
such consents, approvals, orders or authorizations, or to make such filings or
notifications could not reasonably be expected to (A) have, individually or in
the aggregate, a material adverse effect on Buyer considered together with all
of its subsidiaries as a whole, or (B) prevent or delay materially the
consummation of the transactions contemplated by this Agreement.

            7.6 Litigation. Except as set forth in the filings Buyer is required
to make under the Securities Act of 1933, as amended (the "Securities Act"), or
the Securities Exchange Act of 1934, as amended (such filings, collectively, the
"Buyer Securities Filings"), there is no pending or, to the knowledge of the
Buyer, threatened action, suit, arbitration proceeding, charge, complaint,
allegation, investigation, inquiry or other proceeding or claim before any court
or governmental or administrative body or agency or other entity against,
relating to or affecting the Buyer or any director, stockholder, officer, agent
or employee of the Buyer in its, his or her capacity as such, or the assets,
properties or business of the Buyer or the transactions contemplated by this
Agreement.

            7.7 Disclosure. None of the representations or warranties of Buyer
contained in this Section 7, or in any certificate furnished or to be furnished
pursuant to this Agreement pertaining to the same, contains any statement of a
material fact that was untrue when made or omits to state any material fact
necessary to make the statements of fact contained herein or therein not
misleading in any material respect.

any of the Shares now outstanding, and, in the case of the Options, none of the
Stockholders shall exercise any of such Options, and none of the Stockholders
shall grant any options or rights to purchase or exercise (as applicable), or
enter into any agreements which would obligate any of the Stockholders to sell
or exercise (as applicable), or entitle any person or entity to acquire or

thereunder, whether absolute or contingent. Each Stockholder agrees that such
Stockholder will not, and the Stockholders shall cause the Company to not,
directly or indirectly through any of its respective officers, directors,
employees, representatives or agents, (i) solicit, initiate or encourage any
inquiries or proposals (from any person or entity other than Buyer) that
constitute, or could reasonably be expected to lead to, or accept, any proposal
or offer for a merger, consolidation, reorganization, business combination, sale
of substantial assets, sale of shares of capital stock (including, without
limitation, by way of a tender offer), or the issuance of any new securities of
the Company or any other transaction or series of transactions which could cause
or result in a change of control of or any material change in the Company or the
Business, or which could interfere in any manner, directly or indirectly, with
the consummation of the transactions contemplated by this Agreement (any of the
foregoing inquiries or proposals being referred to in this Agreement as an
"Acquisition Proposal"), (ii) engage in negotiations or discussions concerning,
or provide any non-public information to any person or entity relating to or

or records of the Company. Such notice to Buyer shall be made orally and in
writing and shall indicate in reasonable detail the identity of the person or
entity making such Proposal or request and the terms and conditions of such
proposal, inquiry or contact. A proposal for a transaction involving a
Stockholder, not directed toward the Stockholder's interest in the Company, will
not be considered an Acquisition Proposal and will not be restricted by this
Section 8.9.

            8.10 Furnishing of Certain Information. If requested by Buyer, but
at Buyer's expense, the Company will (i) permit Buyer's employees, independent
public accountants or other advisors to have reasonable access to the books and

of this Agreement are included for purposes of convenience only and shall not
affect the construction or interpretation of any of its provisions.

            18.4 Waivers. Any party to this Agreement may waive any right it may

<PAGE>

Agreement. No waiver will be deemed to be a waiver of any subsequent or other

            18.5 Entire Agreement. This Agreement, including the schedules and
Exhibits and other documents referred to herein which form a part hereof,

referring to this Agreement signed by the Buyer and the holders of a majority of
the outstanding Shares.

            18.6 Governing Law. This Agreement is deemed to have been made in
the State of California, and shall be governed by and construed in accordance
with the laws of, the State of California for contracts made and to be performed

Buyer, if necessary, with respect to the making of a public communications
release relating to this Agreement. Except as may be required by applicable law,
neither the Stockholders nor the Company, on the one hand, nor Buyer, on the
other hand, shall issue any press releases or other public communications
relating to this Agreement or the transactions contemplated hereunder without
the prior written consent of the other. In the event that any such press release
or other public communication shall be required by applicable law, each party
shall first consult in good faith with the others with respect to the form and
substance of such release or communication.

            18.8 Disputes; Arbitration. In lieu of litigation, all disputes
concerning this Agreement or any attachment hereto or any asserted breach hereof
shall be resolved as follows:

                  (a) Cooperation. The parties agree to cooperate with each
other to attempt to settle all disputes arising under this Agreement without
resort to mediation or arbitration.

                  (b) Mediation. If the parties are unsuccessful in resolving a
dispute within forty five (45) days from the date the parties begin attempting
to resolve it, either party may submit the dispute to a mediation administered
by Judicial Arbitration & Mediation Services, Inc. ("JAMS"), by requesting in
writing to JAMS and the other party that a mediation settlement conference be
scheduled. Each party shall use best efforts to complete the mediation within
forty-five (45) days after such notice pursuant to the rules of JAMS. The
mediation shall take place in Orange County, California. The parties shall
attempt in good faith to reach agreement on the appointment of a retired judge
from the JAMS panel as mediator. If they cannot agree within twenty (20) days
after such notice, JAMS will provide a list of three available retired judges
(which judges, to the extent available on a timely basis, should have
substantial experience in the area of the dispute) and each party may strike one
name from the list. The remaining judge shall be appointed as mediator. The
parties shall each pay their own expenses of mediation, including attorney's
fees, and shall share equally the mediator's fees and expenses.

                  (c) Arbitration. Except for any action for injunctive or any
other equitable remedies, all disputes which are not resolved through
cooperation and mediation shall be finally resolved by binding arbitration by a
single arbitrator in accordance with the Federal Arbitration Act, 9 USCA 1, et.
seq. in effect at the time. Each party to this Agreement can initiate

                                       38
<PAGE>

arbitration pursuant to this Agreement by serving notice on the other party of
an intent to arbitrate. Each of the parties consents to venue for such
arbitration in Orange County, California. The notice shall specify with
particularity the claims or issues that are to be arbitrated. Within ten days of
receipt of the notice by all parties, the parties shall use all reasonable
efforts to obtain a list of available arbitrators from the appropriate office of
JAMS and select a mutually acceptable arbitrator. If the parties are unable to
agree on an arbitrator within ten days, any party may petition the Presiding
Judge of the forum's Superior Court to select a single arbitrator from the JAMS
list. The parties shall have the discovery rights available under the forum's
Civil Rules, subject to the limitation that each side shall be limited to no
more than five depositions unless, upon a showing of good cause, the party can
convince the arbitrator that more depositions should be permitted. It shall be
the intention of the parties to select an arbitrator and set a schedule
according to the following: (1) all discovery must be concluded within 120 days
of the selection of an arbitrator, (2) the arbitration hearing must be concluded
within 30 days of the close of discovery and it will be conducted in accordance
with the forum's Rules of Evidence, and (3) the arbitrator's final decision
shall be rendered within ten days of the final hearing day. Judgment upon the
arbitrator's final award may be entered in any court having jurisdiction
thereof. The parties shall bear in equal shares the arbitrator's fees and costs.
In those cases where the arbitrator's judgment consists solely of monetary
damages, the prevailing party in the arbitration shall be awarded its reasonable
attorneys' fees and all costs, other than the arbitrator's fees and costs. For
the purpose of determining who is the prevailing party, each side will submit to
the other a single written offer of settlement ten days prior to the start of
the arbitration hearing and the party whose offer most closely resembles the
arbitrator's award shall be deemed the prevailing party for the purpose of
awarding attorneys' fees.

            18.9 Assignment. No Stockholder may assign this Agreement, or assign
its rights or delegate its duties hereunder, without the prior written consent
of Buyer. Prior to the Closing, Buyer may not assign this Agreement, or assign
its rights or delegate its duties hereunder, without the prior written consent
of the Equity Representative.

            18.10 Severability. Any provision of this Agreement which is
illegal, invalid or unenforceable shall be ineffective to the extent of such
illegality, invalidity or unenforceability, without affecting in any way the
remaining provisions hereof.
