                  AND COMPLETE TERMINATION OF, LEASE AGREEMENT

         THIS SEVENTH AMENDMENT TO, AND COMPLETE TERMINATION OF, LEASE AGREEMENT
(the "Seventh Amendment"), is entered into as of June 30, 2004, by and between
GILLESPIE FIELD PARTNERS, LLC, a California limited liability company
("Landlord") and SPARKS EXHIBITS, LTD., a California corporation ("Tenant"),
with reference to the following facts:

         A. Landlord and Tenant are all of the parties to that certain Lease
Agreement dated as of June 29, 1998 (the "Lease"), wherein Landlord leased to
Tenant certain real property located at 2025 Gillespie Way, El Cajon,
California, having located thereon a single industrial building (the "Building")
containing approximately 150,159 square feet of space (the "Original Premises").

         B. Subsequent to execution of the Lease, Tenant's business requirements
changed and Tenant requested that Landlord assist Tenant in locating tenants to
lease portions of the Original Premises. In accordance with Tenant's request,
Landlord previously identified (i) G.T.M. Wholesale Liquidators Inc. ("GTM") as
a prospective tenant to lease a portion of the Original Premises comprising
approximately 40,694 square feet (the "GTM Premises") and Landlord and Tenant
previously entered into (A) that certain First Amendment to Lease Agreement and
Agreement dated as of October 31, 2003 (the "First Amendment"), whereby Landlord
and Tenant agreed to mutually cooperate and undertake to pay for and perform
certain obligations with respect to the GTM Premises and (B) that certain Second
Amendment to, and Partial Termination of, Lease Agreement dated as of January 1,
2004 (the "Second Amendment"), whereby Landlord and Tenant agreed to partially
terminate the Lease with respect to the portion of the Original Premises
comprised of the GTM Premises, and (ii) Professional's Choice Sports Medicine
Products, Inc. ("Professional's Choice") as a prospective tenant to lease a
portion of the Original Premises comprising approximately 37,600 square feet
(the "Professional's Choice Premises") and Landlord and Tenant previously
entered into that certain Third Amendment to Lease Agreement and Agreement dated
as of February 27, 2004 (the "Third Amendment"), whereby Landlord and Tenant
agreed to mutually cooperate and undertake to pay for and perform certain
obligations with respect to the Professional's Choice Premises.

         C. In addition, Landlord and Tenant entered into that certain Fourth
Amendment to, and Agreement to Partially Terminate Lease Agreement, dated as of
March 1, 2004 (the "Fourth Amendment"), whereby Landlord agreed to grant Tenant
an option to partially terminate the Lease further with respect to a portion of
the Original Premises comprising approximately 25,000 square feet and designated
the "Additional Premises" in the Fourth Amendment, subject to the performance of

                                       18
<PAGE>

certain obligations and undertakings set forth in the Fourth Amendment.
Subsequent to entering into the Fourth Amendment, Landlord and Tenant entered
into that certain Fifth Amendment to, and Partial Termination of, Lease
Agreement, dated as of April 1, 2004 (the "Fifth Amendment"), whereby Landlord
and Tenant agreed to partially terminate the Lease with respect to the portion
of the Original Premises comprised of the Professional's Choice Premises and
that certain Sixth Amendment to, and Partial Termination of, Lease Agreement,
dated as of April 30, 2004 (the "Sixth Amendment"), whereby Landlord and Tenant
agreed to partially terminate the Lease with respect to the portion of the
Original Premises designated the "Additional Premises" in the Fourth Amendment.
After giving effect to the Sixth Amendment, the portion of the Original Premises
remaining subject to the Lease was approximately 46,865 square feet (the
"Remaining Premises").

         D. Subsequent to execution of the Sixth Amendment, Tenant has requested
that Landlord terminate the Lease with respect to the Remaining Premises and
effect a complete termination of the Lease in exchange for the payment to
Landlord of certain sums in consideration of Landlord's agreement to so
terminate the Lease, and Tenant's full and complete compliance with other terms
and provisions set forth in this Seventh Amendment. Provided Tenant pays said
sums and otherwise complies with said other terms and provisions, Landlord is
willing to so terminate the Lease.

         E. Accordingly, Landlord and Tenant desire to memorialize the terms,
provisions and conditions upon which the Lease with respect to the Remaining
Premises and otherwise shall be and become completely terminated subject to, and
in accordance with, all terms and provisions of this Seventh Amendment.

         NOW, THEREFORE, in consideration of the mutual covenants, agreements
and undertakings contained in this Seventh Amendment and the exchange of other
good and valuable consideration, the receipt and sufficiency of which is hereby
acknowledged, the parties hereto agree as follows:

         1. Definitions. Unless defined in this Seventh Amendment, or except as
otherwise expressly provided in this Seventh Amendment, capitalized terms
utilized in this Seventh Amendment shall have the meanings ascribed to such
terms in the Lease.

         2. Mutual Termination of the Lease; Termination Payment; Effective
Date. Landlord and Tenant hereby agree and acknowledge that subject to (i)
payment by Tenant of the sum of $163,089.60 (the "Lease Termination Payment") to
Landlord pursuant to the terms and conditions of this Section 2 set forth below,
(ii) Tenant's having terminated any tenancies, subtenancies, or other occupancy
agreements and/or arrangements with any tenant(s) and/or occupant(s) of the
Remaining Premises and all of such tenant(s) and/or occupant(s) having vacated
the Remaining Premises and delivered up and surrendered possession of the
Remaining Premises to Tenant on or before June 30, 2004 (the "Effective Date")
and (iii) subject to the delayed complete surrender of the Remaining Premises as
set forth below in this Section 2, Tenant's having in turn delivered up and
surrendered possession of the Remaining Premises to Landlord on or before the

                                       19
<PAGE>

Effective Date, the Lease shall be and become completely terminated on the
Effective Date, both with respect to the Remaining Premises and otherwise.
Landlord and Tenant agree and acknowledge that a portion of the Lease
Termination Payment is comprised of Landlord's estimate of the common area
maintenance/operating expenses for calendar year 2004 in the aggregate amount of
$28,119 (the "CAM Estimate"), calculated at the rate of $0.10 per square foot of
the Remaining Premises for each of the remaining months of calendar year 2004,
July, 2004, through December, 2004. Landlord and Tenant agree that only the CAM
Estimate portion of the Lease Termination Payment shall be subject to the final
reconciliation procedures set forth in Section 11.3 of the Lease, and any
underpayment or overpayment, as the case may be, shall be paid by Tenant or
refunded by Landlord, as applicable, within five (5) days of Landlord's
transmission to Tenant of Landlord's statement required by Section 11.3 of the
Lease. Tenant shall also have the continuing right to a final reconciliation of
common area maintenance/operating expenses, pursuant to Section 11.3 of the
Lease, paid by Tenant during calendar year 2004 and prior to the Effective Date.
Landlord is currently holding a security deposit in the sum of $30,782 provided
by Tenant to Landlord at the commencement of the Lease pursuant to Section 3.6
of the Lease. Landlord agrees to apply said security deposit to the outstanding
obligations due to Landlord, as set forth in Landlord's ledger dated as of June
29, 2004, which ledger is attached to this Seventh Amendment as Exhibit A (the
"Ledger"). The portion of the Lease Termination Payment remaining outstanding
and unpaid after application of the security deposit as shown in the Ledger,
namely, $158,307.60, shall be due and payable by Tenant to Landlord in six equal
installments of $26,384.60 each, commencing July 9, 2004 and so continuing on
the first day of each calendar month thereafter until December 1, 2004, on which
latter date the final installment shall be due and payable. Installments of the
Lease Termination Payment which are not paid when due are subject to the late
charge and default interest provisions, if any, set forth in the Lease.
Notwithstanding Landlord's agreement with Tenant to completely terminate the
Lease with respect to the Remaining Premises and otherwise as of the Effective
Date, as aforesaid, (1) Tenant shall remain fully obligated and liable to pay to
Landlord sums which Tenant has agreed to pay pursuant to the terms and
provisions of this Seventh Amendment, which have not, as of the Effective Date,
been paid, until such time as Tenant shall have fully discharged and satisfied
said obligations, (2) Tenant shall have until the close of business on Friday,
July 16, 2004 (the "Final Surrender Date"), to completely vacate and surrender
the Remaining Premises, provided however that Tenant acknowledges that Landlord
will be installing certain tenant improvements and otherwise configuring the
Remaining Premises for occupancy by a new tenant (collectively, "Landlord's
Work") during the period between the Effective Date and the Final Surrender Date
and, in consideration of Landlord's permitting Tenant to continue to occupy
portions of the Remaining Premises until the Final Surrender Date, Tenant agrees
to organize and consolidate its remaining personal property during the period
between the Effective Date and the Final Surrender Date in accordance with
Landlord's reasonable requests and in areas of the Remaining Premises which will
permit Landlord's Work to proceed without unreasonable interference during said
period, and (3) this Seventh Amendment shall not be construed or interpreted to
alter, amend and/or modify Landlord and Tenant's respective responsibilities and
obligations to each other under and by reason of the Lease, to the extent (but
only to the extent) that any such responsibilities and obligations arose prior
to the Effective Date and would have continued beyond the date provided in the
Lease for the expiration of its term, in the absence of this Seventh Amendment.
