THIS LOAN AND SECURITY AGREEMENT ("Loan Agreement"), dated the above date, is

division of Southern Pacific Thrift & Loan Association ("Coast"), a California
corporation, with offices at 12121 Wilshire Boulevard, Suite 1111, Los Angeles,
California 90025, and the borrower named above ("Borrower"), whose chief
executive office is located at the above address ("Borrower's Address").

* COAST AND THE BORROWER ARE ALSO PARTIES TO THAT CERTAIN LOAN AND SECURITY
AGREEMENT DATED JUNE 19, 1997 (THE "NONCEFO AGREEMENT") AND THE COLLATERAL
AGREEMENTS REFERRED TO THEREIN. BOTH THIS AGREEMENT AND THE NON-CEFO AGREEMENT
AND SUCH OTHER COLLATERAL AGREEMENTS SHALL CONTINUE IN FULL FORCE AND EFFECT,
AND ALL RIGHTS AND REMEDIES OF COAST HEREUNDER AND THEREUNDER ARE CUMULATIVE.

1.       LOANS.

         1.1 LOANS, COLLATERAL AGREEMENTS. Borrower has requested and may
hereafter request that Coast advance funds or otherwise extend credit to or for
the benefit of Borrower ("Loan(s)") in accordance with the terms and provisions
of this Loan Agreement and other written agreements ("Collateral Agreement(s)"),
including, but not limited to, any one or more of the following described
security agreements now or hereafter entered into between Borrower and Coast:
(a) CEFO Collateral Agreement and (d) any promissory notes or guaranties. The
amount and terms of payment of any Loans by Coast to Borrower shall be
determined in accordance with the terms and provisions of this Loan Agreement
and of any executed Collateral Agreements. Notwithstanding anything herein or in
any Collateral Agreement to the contrary, in no event shall the Borrower permit
the total balance of all Loans and all other Obligations (including without
limitation the Obligations under and as defined in the Non-CEFO Agreement)
outstanding at any one time to exceed $13,500,000 ("Maximum Dollar Amount");
and, if for any reason they do, Borrower shall immediately pay the amount of
such excess to Coast in immediately available funds.

         1.2 INTEREST. Unless specifically provided to the contrary in any
Collateral Agreement, all Loans shall bear interest at a rate equal to the

basis of a 360-day year for the actual number 


<PAGE>   2

of days elapsed; provided, however, all Loans shall bear interest at a rate
equal to the Prime Rate plus 1.75% per annum upon receipt of evidence acceptable
to Coast in its sole and absolute discretion that Borrower has achieved and
maintained a Tangible Net Worth (as that term is defined herein) of no less than
$17,000,000. The interest rate applicable to all Loans shall be adjusted monthly
as of the first day of each month, and the interest to be charged for that month
shall be based on the highest "Prime Rate" in effect during said month, but in
no event shall the rate of interest charged on any Loans in any month be less
than 8% per annum. "Prime Rate" is defined as the actual "Reference Rate" or the
substitute therefor of the Bank of America NT&SA ("B of A") whether or not that
rate is the lowest interest rate charged by B of A. If the Prime Rate, as
defined, is unavailable, "Prime Rate" shall mean the highest of the prime rates
published in the Wall Street Journal on the first business day of the month, as
the base rate on corporate loans at large U.S. money center commercial banks.

         1.3 FEES. Borrower shall pay to Coast a loan origination fee in the
amount of n/a concurrently herewith, and an annual loan fee of n/a on each

are in addition to all other sums payable to Coast, are not refundable for any
reason, and shall bear interest from the date due to the date paid at the
highest interest rate applicable to any of the Obligations.

         3.1 CORPORATE EXISTENCE AND POWER. Borrower, if a corporation, is and
will continue to be, due authorized, validly existing and in good standing under
the laws of the jurisdiction of its incorporation. Borrower and will continue to
be qualified and licensed to the business in all jurisdictions in which the
nature of its business transacted by it, or the ownership or leasing of its

                                      -4-
<PAGE>   5

         3.2 AUTHORITY. Borrower is, and will continue to be, authorized to
enter into, to grant security interests in its property pursuant to, and to
perform its obligations under, this Loan Agreement, any Collateral Agreement and
all other instruments and transactions contemplated herein. The execution,
delivery and performance by Borrower of this Loan Agreement, any Collateral
Agreement and all other instruments and transactions contemplated herein have
been validly authorized, are enforceable against the Borrower in accordance with
their terms, and do not violate any law or any provision of Borrower's Articles
of Incorporation, By-Laws and any Shareholder Agreements nor do they violate any
material provision of, nor will they result in acceleration under, any material
agreement, indenture, note or instrument which is binding upon Borrower, or any
of its property.

         3.3 NAME; TRADE NAMES AND STYLES. Borrower has set forth above its
correct name. Listed on the Schedule hereto are all prior names of Borrower and
each fictitious name, trade name and trade style by which Borrower has been, or
is now, known. Borrower shall provide Coast with fifteen (15) days' advance
written notice prior to doing business under any other name, fictitious name,
trade name or trade style. Borrower has complied, and will hereafter comply,
with all laws relating to the conduct of business under, the ownership of
property in, and the renewal or continuation of the right to use, a corporate,
fictitious or trade name or trade style.

         3.4 PLACE OF BUSINESS; LOCATION OF COLLATERAL. Borrower's sole place of
business; or, if Borrower has more than one place of business, Borrower's chief
executive office; or, if Borrower is an individual and does not have a separate
place of business, Borrower's residence is, and will continue to be, located at
Borrower's Address and all of Borrower's books and records, including, but not
limited to, the books and records relating to Borrower's Accounts, are and will
be maintained at Borrower's Address unless and until Coast shall otherwise

business and Collateral is located only at the locations shown on the Schedule
hereto. Borrower will provide Coast with at least fifteen (15) days' advance
written notice if Borrower moves any of the Collateral to any new location not
previously reported to Coast, or obtains any additional sites for the conduct of
Borrower's business or the location of any Collateral.

         3.5 THE TO COLLATERAL; LIENS. Borrower is now, and will at all times
hereafter be, the lawful and sole owner of all the Collateral. With the
exception of the security interest granted Coast, the Collateral now is and will
remain free and clear of any and all liens, charges, security interests,
encumbrances and adverse claims ("Liens"), other than Permitted Liens. As used
herein, "Permitted Liens" means (i) any Liens existing as of the date hereof and
disclosed in Schedule A hereto; (ii) Liens for taxes, fees, assessments or other
governmental charges or levies, either not delinquent or being contested in good
faith by appropriate proceedings, provided the same have no priority over any of
Coast's security interests; (iii) Liens of materialmen, mechanics, warehousemen,
carriers, or employees or other like Liens arising in the ordinary course of
business and securing obligations either not delinquent more than 45 days or
being contested in good faith by appropriate proceedings; (iv) any judgment,
attachment or similar lien, unless the judgment it secures is not fully covered
by insurance and has not been discharged or execution thereof effectively stayed
and bonded against pending appeal within 30 days of the entry thereof provided
that, if the judgment is not fully covered by insurance or 



                                      -5-
<PAGE>   6

execution thereof has not been so stayed and bonded, Coast shall not be required
to make any Loans or otherwise extend credit to or for the benefit of Borrower;
(v) Liens (i) upon or in any equipment acquired or to be acquired, held or
leased by the Borrower to secure the purchase price of such equipment or
indebtedness incurred solely for the purpose of financing the acquisition of
such equipment or (ii) existing on such equipment at the time of its acquisition
or lease, provided that the Lien is confined solely to the equipment so acquired
and improvements thereon; (vi) Leases or subleases and licenses or sublicenses
granted to others not interfering in any material respect with the business of
Borrower; (vii) Encumbrances securing reimbursement obligations of Borrower with
respect to commercial letters of credit, provided that such encumbrances shall
attach only to documents or other property relating to such letters of credit
and products and proceeds thereof that are not Collateral under this Agreement
or any of the Collateral Agreements subsequent to the delivery of such property
to Borrower; (viii) Liens incurred in connection with the extension, renewal or
refinancing of the indebtedness secured by Liens of the type described in
clauses (i) and (v) above, provided that any extension, renewal or replacement
Lien shall be limited to the property encumbered by the existing Lien and the
principal amount of the indebtedness being extended, renewed or refinanced does
not increase; (ix) Liens securing debt junior in perfection and priority to the
lien of Coast which are expressly subordinated to Coast on terms satisfactory to
Coast (including a provision stating that the secured party shall not take
action to enforce its lien so long as any of the Obligations remain
outstanding); (x) Liens in favor of customs and revenue authorities which secure
payment of customs duties in connection with the importation of goods; (xi)
Liens which constitute rights of set-off of a customary nature or bankers' liens
on amounts on deposit, whether arising by contract or by operation of law, in
connection with arrangements entered into with depository institutions in the
ordinary course of business; and (xii) other Liens in existence on the date
hereof and listed on Schedule A hereto. Without limiting any of Coast's other
rights and remedies, if Borrower grants any third patty a lien or encumbrance on
or security interest (other than a Permitted Lien) in any of the Collateral,
Coast, in its sole discretion, shall have the right to treat such action as a
notice of termination by Borrower to Coast under Paragraph 8(d) hereof, as of
any date subsequent to such grant selected by Coast, in its sole discretion, and
to charge Borrower the termination fee therein provided. Coast now has, and will
have, a perfected and enforceable first priority security interest in all of the
Collateral (Other than Collateral subject to a Permitted Lien) to the extent
that such security interest can be perfected by the filing of financing
statements and Borrower will at all times defend Coast and the Collateral
against all claims of others. Borrower is not and will not become a lessee under
any real property lease pursuant to which the lessor may obtain any rights in
any of the Collateral and no such lease now prohibits, restrains, impairs or
will prohibit, restrain or impair Borrower's right to remove any Collateral from
the leased premises. Whenever any Collateral is located upon premises in which
any third party has an interest (whether as owner, mortgagee, beneficiary under
a deed of trust, lien or otherwise), Borrower shall, whenever requested by
Coast, use its best efforts to cause such third patty to execute and deliver to
Coast, in form acceptable to Coast, whatever waivers and subordinations that
Coast specifies, so as to ensure that Coast's rights in the Collateral are, and
will continue to be, superior to the rights of any such third party. Borrower
will keep in full force and effect, and will comply with all the terms of, any
lease of real property where any of the Collateral now or in the future may be
located except for leases of sales offices at which not 



                                      -6-
<PAGE>   7

more than $200,000 in Collateral is located.

         3.6 MAINTENANCE OF COLLATERAL. Borrower has maintained and will
maintain the Collateral and all of its assets in good working condition, at
Borrower's expense. Borrower will not use the Collateral or any of its other
properties for any unlawful purpose and will not secrete or abandon the
Collateral except for the abandonment of worn-out or obsolete equipment or
inventory in the ordinary course of business. Borrower will immediately advise
Coast in writing of any material loss or depreciation of the Collateral.

         3.7 BOOKS AND RECORDS. Borrower has maintained and will maintain at
Borrower's Address books and records which are complete and accurate in all
material respects and which comprise an accounting system in accordance with
generally accepted principles. Borrower has not and will not in the future enter
into any agreement with any accounting firm, service bureau or third parry to
prepare or store Borrower's books and records at any location other than
Borrower's Address, without first obtaining Coast's written consent, which may
be conditioned upon such accounting firm, service bureau or other third party
agreeing to give Coast the same rights with respect to access to books and
records and related rights as Coast has under Paragraph 4.3 of this Loan
Agreement.

         3.8 FINANCIAL CONDITION AND STATEMENTS. All financial statements now or
hereafter delivered to Coast have been, and will be, prepared in conformity with
generally accepted accounting principles and now and hereafter will fairly
reflect the financial condition of Borrower, at the times and for the periods
therein stated. Since the last date covered by any such statement, there has
been no material adverse change in the financial condition, operations or any
other status of the Borrower. Borrower is now and will continue to be solvent in
both the "equity" and "bankruptcy" sense. Borrower will deliver to Coast a copy
of all reports and financial statements pursuant to Schedule 42.

         3.9 TAX RETURNS AND PAYMENTS; PENSION CONTRIBUTIONS. Borrower has
timely filed, and will timely file, all tax returns and reports required by
foreign, federal, state or local law. Borrower has timely paid, and will timely
pay, all foreign, federal, state and local taxes, assessments, deposits and
contributions now or hereafter owed by Borrower. Borrower may defer payment of
any contested taxes provided that Borrower (i) in good faith contests Borrower's
obligation to pay such taxes by appropriate proceedings promptly and diligently
instituted and conducted, (ii) notifies Coast in writing of the commencement of
and any material development in such proceedings, and (iii) posts bonds or takes
any other steps required to keep such contested taxes from becoming a lien
(other than Permitted Liens) against or charge upon any of the Collateral or
other properties of Borrower. Borrower shall, at all times, utilize the services
of an outside payroll service providing for the automatic deposit of all payroll
taxes payable by Borrower. Borrower is unaware of any claims or adjustments
proposed for any of Borrower's prior tax years which could result in additional
taxes becoming due and payable by Borrower. Borrower has paid, and shall
continue to pay all amounts necessary to fund all present and future pension,
profit sharing and deferred compensation plans in accordance with their terms,
and Borrower has not and will not withdraw from participation in, permit partial
or complete termination of, or permit the (occurrence of any other event with
respect to, any such 



                                      -7-
<PAGE>   8

plan which could result in any liability of Borrower, including, without
limitation, any liability to the Pension Benefit Guaranty Corporation or its
successors or any other governmental agency. When requested, Borrower will
furnish Coast with proof satisfactory to Coast of Borrower's making the payment
or deposit of all such taxes and contributions, such proof to be delivered
within five (5) days after the due date established by law for each such payment
or deposit. If Borrower fails or is unable to pay or deposit such taxes or
contributions, Coast may, but is not obligated to, pay the same and treat all
such advances as additional Obligations of Borrower. Such advances shall bear
interest at the highest interest rate applicable to any of the Obligations.

         3.10 COMPLIANCE WITH LAW. Unless noncompliance would not materially
adversely affect (i) Borrower's financial condition as reflected in its
financial statements previously delivered to Coast; (ii) Borrower's operations;
or (iii) Borrower's business, Borrower has complied, and will comply, with all
provisions of all foreign, federal, state and local laws and regulations
relating to Borrower, including, but not limited to, those relating to
Borrower's ownership of real or personal property, conduct and licensing of
Borrower's business and employment of Borrower's personnel.

         3.11 LITIGATION. There is no claim, suit, litigation, proceeding or
investigation pending or threatened by or against or affecting Borrower in any
court or before any regulatory commission, board or other governmental agency
(or any basis therefor known to borrower) which is reasonably likely to result,
either separately or in the aggregate, in any material adverse change in the
business or condition of Borrower, or in any impairment in the ability of
Borrower to carry on its business in substantially the same manner as it is now
being conducted involving any single claim of $50,000 or more, or involving
$100,000 or more in the aggregate. Borrower will immediately inform Coast in
writing of any claim, proceeding, litigation or investigation hereafter
threatened or instituted by or against Borrower involving any single claim of
$50,000 or more, or involving $100,000 or more in the aggregate.

         3.12 USE OF PROCEEDS. Borrower is not purchasing or carrying any
"margin stock" (as defined in Regulation G of the Board of Governors of the
Federal Reserve System) and no part of the proceeds of any Loan will be used to
purchase or carry any "margin stock" or to extend credit to others for the
purpose of purchasing or carrying any "margin stock." All proceeds of all Loans
shall be used solely for lawful business purposes.

         3.13 CONTINUING EFFECT. All representations, warranties and covenants
of Borrower contained in this Loan Agreement and any Collateral Agreement and
any other agreement with Coast shall be true and correct at the time of the
effective date of each such agreement and shall be deemed continuing and shall
remain true, correct and in full force and effect until payment and satisfaction
in full of all of the Obligations, and Borrower acknowledges that Coast is and
will be expressly relying on such representations, warranties and covenants in
making Loans to Borrower.

4.       ADDITIONAL DUTIES OF BORROWER.

         4.1 INSURANCE. Borrower shall, at all times, at Borrower's expense,
insure all of the Collateral and carry such other business insurance with
insurers reasonably acceptable to Coast, 



                                      -8-
<PAGE>   9

in such form and amounts as Coast may reasonably require. All such insurance
policies shall name Coast as an additional loss payee, shall provide that
proceeds payable thereunder be payable directly to Coast unless written
authority to the contrary is obtained, and shall also provide that no act or
default of Borrower or any other person shall affect the right of Coast to
recover thereunder and shall contain a lenders loss payee endorsement in form
acceptable to Coast. Upon receipt of the proceeds of any such insurance, Coast
shall apply such proceeds in reduction of the Obligations as Coast shall
determine in its sole and absolute discretion provided that if (I) no Event of
Default has occurred and is continuing, and (ii) the proceeds are less than
$50,000 and (iii) the proceeds relate to Collateral which Is not inventory to be
untitled to fulfill "Eligible Purchase Orders" (as defined in the CEFO
Collateral Agreement of even date), then Coast shall release the same to the
Borrower for the repair or replacement of the property affected. If Borrower
fails to provide or pay for any such insurance, Coast may, but is not obligated
to, procure the same at Borrower's expense. Borrower agrees to deliver to Coast,
promptly as rendered, copies of all material reports made to all insurance
companies.

         4.2 REPORTS. At its expense, Borrower shall report, in form
satisfactory to Coast, such information as Coast may from time to time
reasonably specify regarding Borrower or the Collateral including, without
limitation, the written reports set forth in the Schedule hereto; such reports
shall be rendered with such frequency as Coast may reasonably specify. All
reports furnished Coast shall be complete and accurate in all material respects.

         4.3 ACCESS TO COLLATERAL, BOOKS AND RECORDS. At any time Coast, or its
agents, shall have immediate access to the Collateral and any other property of
Borrower, wherever located provided that if no Event of Default has occurred and
is continuing, such access shall be on one business days notice and during
normal business hours. Coast shall have the right to audit and copy Borrower's
books and records and accounts including accountants' reports wherever located
(hereinafter collectively the "Records"). Such audits shall be at Borrower's
expense and the charge for the audits shall be $750 per person per day (or such
higher amount as shall represent Coast's then current standard charge for the
same), plus reasonable out of pocket expenses. Borrower will not enter into any
agreement with any accounting firm service bureau or third party to store
Borrower's books or records at any location other than Borrower's Address,
without first notifying Coast of the same and obtaining the written agreement
from such accounting firm service bureau or other third party to give Coast the
same rights with respect to access to books and records and related rights as
Coast has under this Loan Agreement. Borrower hereby irrevocably authorizes and
directs any of the officers, agents, accountants and attorneys having possession
or control of any of the Records (including computer records) to physically
deliver or make same available to Coast upon Coast's request. Coast shall have
the right to possession of, or to move to the premises of Coast or any agent of
Coast, for so long as Coast may desire, all or any part of the Records. All of
the rights of Coast under this Section 4 shall be subject to the provisions of
Section 14.11 of this Agreement.

         4.4 PROHIBITED TRANSACTIONS. Borrower shall not without Coast's prior
written consent, merge, consolidate, dissolve, acquire any other corporation;
enter into any transaction not in its usual course of business; guarantee or
otherwise become in any way liable with respect to the obligations of another
parry or entity (except by endorsements of instruments or items of 



                                      -9-
<PAGE>   10

payment for deposit to the general account of Borrower or which are transmitted
or turned over to Coast on account of the Obligations); pay or declare any
dividends upon Borrower's stock; except that Borrower may repurchase or redeem

times as Coast deems fit, or on Coast's premises, or elsewhere and the
Collateral need not be located at the place of disposition. Coast may directly
or through any affiliated company purchase or lease any Collateral at any such

expenses, costs, liabilities and obligations incurred by Coast with respect to
the foregoing shall be added to and become part of the Obligations, shall be due
on demand, and shall bear interest at a rate equal to the highest interest rate

discretion of other or different times, places and manners of noticing and
conducting any disposition of Collateral shall not be deemed unreasonable): Any
public or private disposition as to which on no later than the tenth calendar
day prior thereto written notice thereof is mailed or personally delivered to
Borrower and, with respect to any public disposition, on no later than the tenth
calendar day prior thereto notice thereof describing in general non-specific
terms, the Collateral to be disposed of is published once in a newspaper of
general circulation in the county where the sale is to be conducted, at any
place designated by Coast, with or without the Collateral being present, and

generally of the foregoing, Borrower expressly agrees that, with respect to any
disposition of Accounts, instruments and general intangibles (collectively

any inquiries) concerning the Receivables offered for disposition, including,
but not limited to, the terms of payment, aging and delinquency, if any, of the

guarantor thereof, any collateral therefor and the condition and location of the
goods, if any, that are the subject of any of the Receivables.

         6.4 APPLICATION OF PROCEEDS. All proceeds realized as the result of any
disposition of the Collateral shall be applied by Coast first to the costs,
expenses, liabilities, obligations and attorneys' fees incurred by Coast in the
exercise of its rights under this Loan Agreement and any Collateral Agreement,
second to the interest due upon any of the Obligations and third to the
principal of the Obligations in any order determined by Coast in its sole
discretion. The surplus, if any, shall be paid to Borrower; if any deficiency
shall arise, Borrower shall remain liable to Coast therefor. If, as a result of
the disposition of any of the Collateral, Coast directly or indirectly enters
into a credit transaction with any third patty, Coast shall have the option,
exercisable at any time, in its sole discretion, of either reducing the
Obligations by the principal amount of such credit transaction or deferring the
reduction thereof until the actual receipt by Coast of cash therefor from such
third party.

rights or remedies shall not be deemed an election, nor bar Coast from
subsequent exercise or partial exercise of any other rights or remedies. The
failure or delay of Coast to exercise copy rights or remedies shall not operate
as a waiver thereof, but all rights and remedies shall continue in full force
and effect until all of the Obligations have been fully paid and performed.

fees, including, but not limited to, attorneys' fees and costs incurred in the
enforcement of execution upon or defense of any order, decree, award or
judgment. All attorneys' fees and costs to which Coast may be entitled pursuant
to this Paragraph shall immediately become part of Borrower's Obligations, shall
be due on demand, and shall bear interest at a rate equal to the highest
interest rate applicable to any of the Obligations.

13.      DESTRUCTION OF BORROWER'S DOCUMENTS; LIMITATION OF ACTIONS.

         Any documents, schedules, invoices or other papers delivered to Coast
may be destroyed or otherwise disposed of by Coast six (6) months after they are
delivered to Coast unless Borrower makes written request therefor and pays all
expenses attendant to their return, in which event, Coast shall return same when
Coast's actual or anticipated need therefor has terminated. Borrower agrees that
any claim or cause of action by Borrower against Coast, its directors, officers,
employees, agents, accountants or attorneys, based upon, arising from, or
relating to this Loan Agreement, or any Collateral Agreement, or any other
present or future agreement, or any other transaction contemplated hereby or
thereby or relating hereto or thereto, or any other matter, cause or thing
whatsoever, occurred, done, omitted or suffered to be done by Coast, its
directors, officers, employees, agents, accountants or attorneys, relating in
any way to Borrower, shall be banned unless asserted by Borrower by the delivery
of a specific written claim setting forth in reasonably specific detail the
Borrower's claim or cause of action within one year after the first act,
occurrence or omission upon which such claim or cause of action, or any part
thereof, is based. Borrower agrees that such one-year period of time is a
reasonable and sufficient time for Borrower to investigate and act upon any such
claim or cause of action. The six-month period provided herein shall not be
waived, tolled, or extended except by the written concept of Coast in its sole
and absolute discretion. This provision shall survive any termination, however
arising, of this Loan Agreement, any Collateral Agreement, and any other present
or future agreement.

14.      GENERAL PROVISIONS.

         14.1 SEVERABILITY. Should any provision, clause or condition of this
Loan Agreement or any Collateral Agreement be held by any court of competent
jurisdiction to be void or unenforceable, such defect shall not affect the
remainder of this Loan Agreement or any Collateral Agreement.

         14.2 INTERVENTION. This Loan Agreement and any Collateral Agreements
and such other agreements, documents and instruments as may be executed in
connection herewith shall be construed as the entire and complete agreement
between Borrower and Coast and shall supersede all prior negotiations, all of
which are merged and integrated herein.

         14.3 AMENDMENT. The terms and provisions of this Loan Agreement and any
Collateral Agreement may not be waived or amended except in a writing executed
by Borrower and a duly authorized officer of Coast.

         14.4 TUNE OF ESSENCE. Time is of the essence in the performance by
Borrower of each and every obligation under this Loan Agreement and any
Collateral Agreement.

         14.5 BENEFICIAL OF AGREEMENT. The provisions of this Loan Agreement and
any Collateral Agreement shall be binding upon and inure to the benefit of the
respective successors, assigns, heirs, beneficiaries and representatives of the
patties hereto; provided, however, that Borrower may not assign or transfer any
of its rights under this Loan Agreement or any Collateral Agreement without the
prior written consent of Coast, and any prohibited assignment shall be void. No
consent by Coast to any assignment shall relieve Borrower or any guarantor from
its liability for the Obligations.

         14.6 JOINT AND SEVERAL LIABILITY. The liability of each Borrower shall
be joint and several and the compromise of any claim with, or the release of,
any Borrower shall not constitute a compromise with, or a release of, any other
Borrower.

         14.7 PARAGRAPH HEADINGS; CONSTRUCTION. Paragraph headings are used
herein for convenience only. Borrower acknowledges that the same may not
describe completely the subject matter of the applicable paragraph, and the same
shall not be used in any manner to construe, limit, define or interpret any term
or provision hereof. This Loan Agreement and the Collateral Agreements have been
fully reviewed and negotiated between the parties and no uncertainty or
ambiguity in any term or provision of this Loan Agreement or any Collateral
Agreement shall be construed strictly against Coast or Borrower under any rule
of construction or otherwise.

         14.8 GOVERNING LAW; JURISDICTION; VENUE. This Loan Agreement and any
Collateral Agreement and all acts and transactions hereunder and all rights and
obligations of Coast and Borrower shall be governed by and in accordance with
the laws of the State of California. Any undefined term used in this Loan
Agreement or in any Collateral Agreement that is defined in the California
Uniform Commercial Code shall have the meaning therein assigned to that term. As
a material part of the consideration to Coast to enter into this Agreement,
Borrower (i) agrees that all actions and proceedings relating directly or
indirectly hereto shall, at Coast's option, be litigated in courts located
within California, and that the exclusive venue therefor shall be Los Angeles
County; (ii) consents to the jurisdiction and venue of any such court and
consents to service of process in any such action or proceeding by personal
delivery or any other method permitted by law; and (iii) waives any and all
rights Borrower may have to object to the jurisdiction of any such court, or to
transfer or change the venue of any such action or proceeding.

         14.9 EXECUTION BY COAST. This Loan Agreement and any Collateral
Agreement which has been executed and delivered by Borrower to Coast shall not
become effective unless and until executed by a duly authorized officer of
Coast.

         14.10 MUTUAL WAIVER OF JURY TRIAL. BORROWER AND COAST EACH HEREBY WHILE
THE RIGHT TO TRIAL BY JURY IN ANY ACTION OR PROCEEDING BASED UPON, ARISING OUT
OF, OR IN ANY WAY RELATING TO, LOAN AGREEMENT OR ANY COLLATERAL AGREEMENT OR ANY

OMISSIONS OF COAST OR BORROWER ANY OF THEIR DIRECTORS, OFFICERS, EMPLOYEES,
AGENTS, ATTORNEYS OR ANY OTHER PERSONS AFFILIATED WITH COAST OR BORROWER.

         14.11 CONFIDENTIALITY. Coast covenants and agrees, on a continuing
basis, to use reasonable efforts in no event less than the same degree of care
that it exercises with respect to its own proprietary information of the same

disclosure in accordance with applicable law, any Coast Business Credit Loan and
Security Agreement and all proprietary, trade secret or confidential information
provided to or received by Coast from or on account of Borrower or any affiliate
of Borrower, including business plans and forecasts, non-public financial
information, confidential or secret processes, formulae, devices or contractual
information, customer lists, employee relation matters, and any other
information the disclosure of which could reasonably be expected to have a
material adverse impact on the business, finances or operations of Borrower or
its affiliates, provided however the foregoing provisions shall not be effective
