statements of income and retained earnings and changes of financial position for
the fiscal year then ended, and (ii) the unaudited balance sheet and statement
of income of TCI for the eight (8) month period ended August 31, 1997. Said

for all reasonably anticipated material losses and costs and expenses in excess
of expected receipts. The unaudited balance sheet and statements of income of
TCI as of and for the eight (8) month period ended August 31, 1997, are
hereinafter referred to as the "Financial Statements". August 31, 1997 is
hereinafter referred to as the "Balance Sheet Date".

          (i)  Except (1) as and to the extent specifically reflected or
reserved against the balance sheet included in the Financial Statements, (2)
incurred in the ordinary course of business after the Balance Sheet Date, (3)
otherwise disclosed in the Disclosure Schedule, TCI has no direct or indirect
indebtedness, liability, claim, loss, damage, deficiency, obligation or
responsibility, known or unknown, fixed or unfixed, choate or inchoate,
liquidated or unliquidated, secured or unsecured, accrued, absolute, contingent
or otherwise, including, without limitation, liabilities on account of taxes,
other governmental charges or lawsuits brought whether or not of a kind required
by generally accepted accounting principles to be set forth on a financial
statement, which in the aggregate are material to the condition (financial or
otherwise), properties, business, assets or prospects of TCI. TCI has no
knowledge of any circumstances, conditions, events or arrangements which may
hereafter give rise to any liabilities of TCI except in the ordinary course of
business or as otherwise set forth in this Section 5(i).

          (j)  The inventories shown on the balance sheet included in the
Financial Statements consist of items of a quality and quantity useable and

down on the books of TCI to net realizable market value or have been provided
for by adequate reserves. All items included in the inventories are the property
of TCI, except for sales made in the ordinary course of business since the
Balance Sheet Date; for each of these sales either the purchaser has made full
payment or the purchaser's liability to make payment is reflected in the books
of TCI. No items included in the inventories have been pledged as collateral or
are held by TCI on consignment from others. The inventories shown on all the
balance sheets included in the Financial Statements are based on quantities
determined by physical count or measurement, taken within the preceding twelve
(12) months, and are valued at cost on a basis consistent with that of prior
years.

          (k)  The accounts and notes receivable reflected in the balance sheet
included in the Financial Statements arose from valid sales in the ordinary
course of business and have been collected in full since the Balance Sheet Date,
or are collectible at their full amounts, less the reserve set forth in the
balance sheet included in the Financial Statements, which reserve is accurate
and consistent with past practices. All such accounts and notes receivable are
owned by TCI free and clear of any security interests, claims or other
encumbrances of any nature.

          (l)  No account payable of TCI which has arisen subsequent to the
Balance Sheet Date has exceeded Ten Thousand Dollars ($10,000), nor has the
aggregate of such accounts payable exceeded Fifty Thousand Dollars ($50,000).

duration greater than twelve (12) months or an aggregate amount in excess of

course of business and not providing for a duration in excess of six months or
involving aggregate payments or potential liabilities in excess of Three

               (ii) TCI has fulfilled all material obligations required pursuant
     to each material Contract to have been performed by it prior to the date
     hereof, and TCI has no reason to believe that TCI will not be able to
     fulfill, when due, all of its obligations under each Material Contract
     which remain to be performed after the date hereof;

               (iii)  TCI has not received any notice that any party to any of
     the Material Contracts intends to cancel or terminate any such Material
     Contract or to exercise or not to exercise any option thereunder; and

               (iv) TCI is not a party to, nor is any of its property bound by,
     any contract or other agreement which [a] restricts the conduct of its

     businesses and operations, or [c] which contains any unusual or burdensome
     provisions which may materially adversely affect or impair the conduct of
     its businesses and operations in any way.

agreement under which "fringe benefits" (including, but not limited to,
hospitalization plans or programs, medical insurance, vacation plans or
programs, sick leave plans or programs and related benefits) are afforded any
employees of TCI (each of the foregoing is hereinafter referred to as a "Labor
Agreement"). Section 5(u) of the Disclosure Schedule also includes a true and
complete schedule listing the names, total annual compensation, total accrued
vacation and other fringe benefits of each person employed by TCI presently
receiving compensation aggregating in excess of Fifteen Thousand Dollars
($15,000) per year.

     Except as set forth in Section 5(u) of the Disclosure Schedule:

               [a]  Each Labor Agreement is valid, binding, enforceable and in
     full force and effect and there is no default or event which, with notice
     or lapse of time or both, would constitute a default by any party
     thereunder;

               [b]  TCI has not received any notice that any party to any of the
     Labor Agreements intends to cancel or terminate any such Labor Agreement or
     to exercise or not to exercise any option thereunder; and

               [c]  The employment of each employee of TCI (except Roberto
     Frulla who is employed under contract) may be terminated immediately by TCI
     except as otherwise provided by statute or decisional authority.

          (v)  To the best of its knowledge, TCI has complied in all material
respects with all applicable laws, rules and regulations relating to the
employment of labor, including those related to wages, hours, collective
bargaining and the payment and withholding of taxes and other sums as required
by appropriate governmental authorities and has withheld and paid to the

yet due to such authorities, all amounts required to be withheld from such
employees of TCI and is not liable for any arrears of wages, taxes, penalties or
other sums for failure to comply with any of the foregoing. No present or former
employee, officer or director of TCI has any claim against TCI for any matter,
including but not limited to (i) overtime pay; (ii) wages or salary; (iii)
vacation time off or pay in lieu of vacation time off; (iv) any violation of any
statute, ordinance or regulation relating to minimum wages or maximum hours,
work place conditions, or any other matter; or (v) injuries or other damages
which are not fully covered by the TCI's insurance policies. Except as disclosed
in Section 5(v) of the Disclosure Schedule, there is no:

               [a]  Unfair labor practice complaint against TCI pending before
     the National Labor Relations Board or any state or local agency;

               [b]  Material labor grievance pending against TCI.

specified in clauses [a] and [b] above is threatened against TCI; (ii) no union
organizing activities have taken place with respect to TCI; (iii) no base exists
for which a claim may be made under any collective bargaining agreement to which
TCI is a party; and (iv) all key employees of TCI are in good health.

          (w)  All accrued obligations of TCI applicable to its employees,
whether arising by operation of law, by contract or past custom, for payments by
TCI to trusts or other funds or to any governmental agency, with respect to
unemployment compensation benefits, social security benefits or any other
benefits for its employees, with respect to the employment of said employees
through the date hereof have been paid or adequate accruals therefor have been
made in the Financial Statements. Except as disclosed in Section 5(w) of the
Disclosure Schedule:

               (i)  Neither TCI nor any entity that is a member of a group of
     which TCI is a member and that is under common control with TCI
     ("Affiliate"), as defined in Section 414(b) or (c) of the Internal Revenue
     Code (the "Code"), maintains or has any obligations to contribute to, or
     has in effect or has committed to adopt any "Employee Pension Benefit Plan"
     within the meaning of Section 3(2) of ERISA ("Pension Plan") or any
     "Employee Welfare Benefit Plan" within the meaning of Section 3(1) of ERISA
     ("Welfare Plan");

               (ii) Neither TCI nor any entity that is a member of a group of
     which TCI is a member and that is under common control with TCI maintains

          (x)  Section 5(x) of the Disclosure Schedule sets forth a true and
correct list of all policies or binders of fire, liability, workers'
compensation, vehicular or other insurance held by or on behalf of TCI
specifying the insurer, the policy number or covering note number with respect
to binders, and describing each pending claim thereunder of more than Five
Thousand Dollars ($5,000). Such policies and binders are in full force and
effect and are in all material respects in accordance with the customary
insurance requirements for the industry of TCI. TCI is not in default with
respect to any provision contained in any such policy or binder or has failed to
give any notice or present any claim under any such policy or binder in due and
timely fashion. There are no outstanding unpaid claims under any such policy or
binder. TCI has not received a notice of cancellation or non-renewal of any such
policy or binder. TCI has no knowledge of any inaccuracy in any application for
such policies or binders, any failure to pay premiums when due, or any similar
state of facts which may form the basis for termination of any such insurance.
No such policy is terminable or cancelable by the insurer by virtue of the
consummation of the transactions contemplated herein.

          (y)  Except as indicated in Section 5(y) of the Disclosure Schedule,
no single supplier, lessee or customer of TCI is of material importance to TCI.

commercial working relationships and no person who was such supplier, lessee or
customer of TCI at any time since the date of the balance sheet included in the
Financial Statements has cancelled or otherwise terminated, or threatened to
cancel or otherwise terminate its relationship with TCI or has since such date
decreased or limited materially, or threatened to decrease or limit materially,
its services, supplies or

                                         -9-

<PAGE>

materials to TCI or its usage of services or products of TCI, as the case may
be. TCI has no notice that any such supplier, lessee or customer intends to
cancel or otherwise modify its relationship with TCI or to decrease materially
or limit its services or products to TCI or its usage of services or products of
TCI.

          (z)  Except as indicated in Section 5(z) of the Disclosure Schedule,
no officer, director or shareholder of TCI and no key employee of TCI (i) owns,
directly or indirectly, any interest in (excepting not more than a one percent
(1%) share holdings for investment purposes in securities of publicly held and
traded companies), or is an officer, director, employee or consultant of, any
person which is a competitor, lessor, lessee, customer or supplier of TCI; (ii)
holds a beneficial interest in any contract, instrument, obligation, commitment
or agreement to which TCI is a party or under which any of them is obligated or
bound or to which their respective properties may be subject (other than stock
options nd other contracts, commitments or agreements between TCI and such
persons in their capacities as employees, officers or directors of TCI; (iii)
owns, directly or indirectly, in whole or in part, any tangible or intangible
property (including, without limitation, any patent, trademark, trade name,
servicemark, franchise, patent, invention, permit, license or secret or
confidential information) which TCI is using or the use of which is necessary
for the business and operations of TCI; or (iv) has an cause of action or other
claim whatsoever against, TCI, except for claims in the ordinary course of
business, such as for accrued vacation pay, accrued benefits under employee
benefits plans and similar matters and agreements existing on the date hereof.

          (aa) Except as indicated in the Section 5(aa) of Disclosure Schedule,
TCI is not indebted, directly or indirectly, to any person who is an officer,
director or shareholder of TCI nor to any affiliate of any such person in any
amount whatsoever other than for salaries for services rendered or reimbursable
business expenses, all of which have been accrued on the Financial Statements,
and no such officer, director, shareholder or affiliate is indebted to TCI,
except for advances made to employees of TCI in the ordinary course of business
to meet reimbursable business expenses anticipated to be incurred by such
obliger.

          (ab) TCI has no general or special powers of attorney outstanding
(whether as grantor or grantee thereof) or any obligation or liability (whether
actual, accrued, accruing, contingent or otherwise) as guarantor, surety,
co-signer, endorser, co-maker, indemnitor or otherwise in respect of the
obligation of any person, corporation, partnership, joint venture, association,
organization or other entity.

          (ac) Except as indicated in Section 5(ac) of the Disclosure Schedule,
since July 8, 1997 (the date of the letter of intent between TCI and Westminster
with respect to the Loan), there have been no material modifications or
amendments to any contract or other agreement, to which TCI and any officer,
director, employee or shareholder of TCI is a party, which would benefit,
directly or indirectly, any such officer, director, employee or shareholder.

          (ad) TCI has furnished or made available to Westminster for its
examination the following, each of which is accurate and complete in all
material respects:

               (i)  Copies of the Articles of Incorporation, Bylaws or other
     charter documents of TCI as in effect on the date hereof;

               (ii) The minute books of TCI containing all proceedings,
     consents, actions and meetings of its Board of Directors;

               (iii)  Copies of all permits, orders and consents with respect to
     TCI and its securities issued by any administrative agency or governmental
     body regulating the issuance or transfer of such securities and all
     applications for such permits, orders and consents;

               (iv) The transfer books of TCI setting forth all transfers of its
     securities;

               (v)  All ledgers, financial records, books of account and files
     of TCI.

                                         -10-

<PAGE>

          (ae) TCI does not know or have reason to know of any material facts or
contingencies which might adversely affect the financial condition, business,
operations or prospects of TCI or the value or condition of its properties and
assets.

          (af) TCI has made available or delivered to Westminster true and
current copies of all agreements and documents referred to in the Disclosure
Schedule.

          (ag) To the best of its knowledge, all documents and other papers
delivered by or on behalf of TCI in connection with this Agreement and the
transactions contemplated hereby are true, complete and authentic. The
information furnished to Westminster by or on behalf of TCI in connection with
this Agreement and the transactions contemplated hereby does not contain any
untrue statement of a material fact and does not omit to state any material fact
necessary to make the statements made, in the context in which made, not false
or misleading. There is no fact which TCI has not disclosed to Westminster in
writing which materially adversely affects, or so far as TCI can now foresee
will materially adversely affect, the business or condition (financial or
otherwise) of TCI.

          (ah) The representations and warranties contained in this section
shall be due and complete on and as of the date of funding of the Loan with
the same force and effect as though such representations and warranties had
been made on and as of that date.

     6.   As long as any portion of the Loan remains unpaid, TCI agrees as
follows:

          (a)  It will keep and maintain full and accurate books, accounts and
records of operations of its business in accordance with generally accepted
accounting principles, consistent with principles heretofore applied by TCI and
it will permit Westminster, by its duly authorized agents, to inspect and copy
such books, accounts and records at any reasonable time.

          (b)  It will furnish to Westminster, promptly after any written
request, such periodic financial information concerning TCI and its business
including, without limitation, internally generated monthly operating
statements, as Westminster shall request. TCI shall furnish to Westminster,
promptly after the same becomes available, but in any event within sixty (60)
days after the end of each fiscal year of TCI, a balance sheet and income
statement covering TCI for the preceding fiscal year, which statements shall
be certified by an executive officer of TCI as having been prepared in
accordance with generally accepted accounting principals and as being true,
correct, complete and accurate. If any such certified annual statement is not
furnished as required hereunder, Westminster shall have the right, but not
the obligation, to obtain any of such statements by means of an audit by an
independent certified public accounting firm selected by Westminster, in
which event TCI covenants and agrees to pay, or to reimburse Westminster for,
any expense of said accounting firm and further agrees to provide all
necessary information to said accountant and to otherwise cooperate in the
making of such audit.

          (c)  It will maintain and preserve its existence and its right to
transact business in the State of California and in all other states in which it
conducts business, and it will not merge or consolidate with any other unrelated
entity.

          (d)  It will notify Westminster in writing of the occurrence of any of
the following within five (5) days of obtaining knowledge thereof: (i) any
material adverse change in the business, property, assets, operations or
condition, financial or otherwise, of TCI, (ii) receipt of notice of any default
under any Material Contract, or (iii) the pendency or threat of any material
litigation or arbitration and of any tax deficiency or other proceeding before
any governmental body or official affecting TCI.

          (e)  It will not incur any indebtedness, secured or unsecured, except
for (i) trade indebtedness incurred in the ordinary course of business or (ii) a
loan facilitated by the City of San Diego under the EM-TEK program, such loan
not to exceed Two Hundred Thousand Dollars ($200,000).

                                         -11-

<PAGE>

          (f)  It will not extend incentive stock options to its employees
except under a "phantom stock plan" approved by Westminster, and any such
incentive stock options shall not exceed in the aggregate fifteen percent (15%)
of the "capital stock" of TCI prior to the conversion of the Loan by
Westminster.

          (g)  It will not amend or modify in any respect any of the new notes
described in Paragraph 7(c) hereof, or give any security for any of said notes,
or prepay any of said notes in whole or in part (except as expressly provided in
said notes).

          (h)  It will not increase any compensation or fringe benefits payable
to any of the shareholders of TCI, or any spouse, child or other relative or
affiliate thereof.

          (i)  It will not make any loans to or guarantee the obligations of
any of the shareholders of TCI, or any spouse, child or other relative or
affiliate thereof.

          (j)  It will not declare and/or pay any dividends to any of the
shareholders of TCI.

     7.   The following constitute conditions, for the benefit of Westminster,
to the funding of the Loan:

          (a)  All of the representations and warranties of TCI herein shall
have been true and correct in all material respects when made, and on the date
of the Loan funding. If requested by Westminster, an officer of TCI shall
execute a certificate to this effect on the date of the funding of the Loan.

          (b)  TCI shall have performed all of its obligations and covenants
under this Agreement.

          (c)  All existing loans made to TCI by Maria L. Frulla, Stefano G.
Frulla, and Enrica F. Frulla (being approximately Seven Hundred Fifty Thousand
Dollars ($750,000) in the aggregate) shall have been novated and recast, and
shall have been evidenced by new notes, which shall be in the form of Exhibit
"F" attached hereto and made a part hereof by reference. The new notes shall
not be secured (any security held under the existing loans shall be released)
and shall be and remain subordinate to the Loan.

     8.   In addition to and without limitation of any other obligation of TCI
hereunder or under any of the documents evidencing the Loan, TCI shall and does
hereby indemnify, defend and agree to hold Westminster harmless from and against
all claims, injury, damage, liability loss, cost and expense of any and every
kind (including attorneys' fees and costs) arising out of or in connection with
the business or operations of TCI, including, but not limited to, product
liability claims. The obligations of TCI under this paragraph shall survive the
repayment of the Loan, but shall not apply to any events which occur subsequent
to the conversion of the Note into capital stock, as described in Paragraph 4
hereof.

     9.   All notices required or permitted to be given pursuant to this
Agreement shall be in writing, and shall be delivered either personally, by
overnight delivery service or by U.S. certified or registered mail, postage
prepaid, return-receipt requested and addressed to the parties at their
respective addresses as they appear below their signatures hereon. Notices may
also be given by facsimile transmission to the facsimile telephone numbers which
appear below the parties' respective signatures hereon, provided that either (a)
receipt of the facsimile transmission is acknowledged in writing by the
receiving party, which may also be by a facsimile transmission, or (b) the
transmitting party obtains a written confirmation from its own facsimile machine
showing that the entire transmission was transmitted to the receiving party,
without interruption, and a copy of the notice is also sent by one of the other
above-described methods of service. The parties may change their addresses or
facsimile telephone numbers for notice by giving notice of such change in
accordance with this section. Notices sent by overnight delivery service shall
be deemed received on the business day following the date of deposit with the
delivery service. Mailed notices shall be deemed received upon the earlier of
the date of delivery shown on the return-receipt, or the second business day
after the date of mailing. Notices sent by facsimile transmission shall be
deemed served on the date of transmission, provided that such notices are sent
during regular business hours, otherwise on the next business day.

                                         -12-

<PAGE>

     10.  This Agreement has been executed in and is to be performed in the
State of California, and this Agreement shall be interpreted in accordance with
the laws of the State of California.

     11.  This Agreement shall be binding upon and inure to the benefit of the
parties hereto, and their respective heirs, assigns, successors-in-interest, and
legal representatives.

     12.  This Agreement may not be amended, modified or altered except by a
written instrument executed by all parties hereto.

     13.  No party has made any representations, warranties, covenants or
promises relating to the subject matter of this Agreement except as set forth
herein, and any prior agreements or understandings not specifically set forth
herein shall be of no force or effect. This Agreement constitutes the entire
agreement of the parties relative to the subject matter hereof. Without limiting
the generality of the foregoing, it is understood and agreed that this Agreement
supersedes that written letter of intent dated July 8, 1997.

     14.  If any provision of this Agreement is declared by a court of competent
jurisdiction to be invalid or unenforceable, the remaining provisions hereof
shall nevertheless be given full force and effect.

     15.  As used herein, the masculine, feminine or neuter gender, and the
singular or plural number, shall each be deemed to include the others whenever
the context so indicates.

     16.  Should any party be required to bring legal action (including
arbitration) to enforce his rights under this Agreement or under the Note or any
of the Loan Documents (as defined in the Note), the prevailing party in such
action shall be entitled to recover from the losing party his reasonable
attorneys' fees and costs in addition to any other relief to which he is
entitled. Such recovery of attorneys' fees shall include any attorneys' fees
incurred in connection with any bankruptcy or reorganization proceeding,
including stay litigation. The parties further agree that any attorneys' fees
incurred in enforcing any judgment are recoverable as a separate item, and that
this provision is intended to be severable from the other provisions of this
Agreement, shall survive the judgment, and is not to be deemed merged into the
judgment.

     17.  This Agreement may be executed in one (1) or more counterparts, each
of which shall be deemed to be an original, but all of which together shall
constitute one (1) and the same instrument.

     18.  The failure of any party, at any time, to require timely
performance by any other party of any provision of this Agreement shall not
affect such party's rights thereafter to enforce the same, nor shall the
waiver by any party of any breach of any provision of this Agreement, whether
or not agreed to in writing, be taken or held to be a waiver of the breach of
any other provision or a waiver of any subsequent breach of the same
provision of this Agreement. No extension of time for the performance of any
obligation or act hereunder shall be deemed to be an extension of time for
the performance of any other obligation or act hereunder.

     19.  The parties agree to perform such further acts and to execute,
acknowledge and deliver such documents as may be necessary to effectuate the
provisions of this Agreement.

     20.  Any controversy or claim arising out of or relating to this Agreement,
or breach thereof, shall be settled by binding arbitration in Los Angeles,
California, in accordance with the Commercial Arbitration Rules of the American
Arbitration Association then in effect, and judgment upon the award rendered by
the arbitrator(s) may be entered in any court of competent jurisdiction. The
cost of arbitration shall be borne by the losing party, or, if there is no
losing party, as the arbitrator(s) shall determine.

     In any arbitration proceedings relative to this Agreement, or breach
thereof, all parties shall have the right to take depositions and to obtain
discovery regarding the subject matter of the arbitration pursuant to California
Code of Civil Procedure Section 1283.05, or any successor statute.

     Service of any Petition to confirm or vacate the Arbitration award and
Notice of Hearing thereon may be made by certified or registered mail,
return-receipt requested, or by personal delivery.

                                         -13-

<PAGE>

     The arbitrator'(s) award may be limited to a statement that one party pay
to the other a sum of money. The arbitrator(s) will not be deemed to exceed
their powers (per California Code of Civil Procedure Sections 1286.2 or 1286.6)
by committing an error of law or legal reasoning, it being agreed that the
decision of the arbitrator(s) shall be final and unreviewable for error of law
or legal reasoning of any kind.

     21.  Notwithstanding the provisions of Paragraph 20 of this Agreement,
before either party files a demand for arbitration, or commences any legal
action (except to the extent that legal action may reasonably be required to
obtain provisional remedies, such as injunctive relief) both parties agree to
mediate, in good faith, any dispute or claim arising between them out of this
Agreement or under the Note or the Loan Documents (as defined in the Note). Such
mediation shall take place in Los Angeles, California before an impartial and
neutral professional mediator selected by mutual agreement of the parties, who
will be authorized to facilitate resolution of the dispute, but who will not be
empowered to impose a settlement on the parties. Mediation fees shall be divided
equally between the parties. If any party commences arbitration or legal action
based on a dispute or claim which should be mediated pursuant to this Paragraph
without first offering to mediate such dispute or claim, and if such party
thereafter refuses to submit to mediation upon written demand by the other
party, then in the discretion of the arbitrator or judge, as the case may be,
such party shall not be entitled to recover its attorneys' fees even if it is
the prevailing party in such arbitration or legal action.

     IN WITNESS WHEREOF, the parties have executed this Agreement as of the date
first above written.
