                           Memorandum of Understanding

This  memorandum  of  understanding  ("Memorandum")  is  intended to clarify and
further document an agreement regarding the ownership interests in the Sold-Rite
project  ("Project") and the subsidiary  company structures which are associated
with that Project,  previously reached among the members of the TM Century Board
of Directors  ("Board") on July 31, 2002  ("Agreement").  It is the intention of
each Board Member to fully disclose to all relevant parties, all aspects of this
Agreement.

On July 31, 2002, the Board, in executive session, discussed various alternative
paths of action with respect to ownership and collateral  commitments  regarding
this Project and the relative merits of each  alternative.  It was determined by
the Board that the following  determinations  listed below are agreed upon,  are
deemed to be fair to all parties, and are in the best interest of TM Century and
its  shareholders.  In the case of  votes  taken or  approvals  granted  in this
matter, both David Graupner and Michael Cope abstained from voting.

1. Initial ownership interest in the Sold-Rite project shall be as follows:

              42.5% owned by TM Century
              42.5% owned by David Graupner
              15% owned by Michael Cope

2. It is understood  that this Project is to be set up in a subsidiary  intended
to limit TM Century's liability.  Although set up as a subsidiary, it is not the
intention  of the  Board  to do this in  order  to  misdirect,  deceive  or hide
information from the shareholders,  the public or any governmental agency. It is
further  agreed that funds  provided by TM Century  with respect to this project
will be limited to  $100,000.  A decision to fund the Project  beyond that point
would require specific approval of the Board.

3. It is understood  that in order to raise capital to fund the new venture,  to
attract  management  and  other  employees,  and to bring in  various  strategic
partners  who may provide  other  forms of value  critical to the success of the
venture, additional ownership interests or options, or warrants thereto, will be
created.  It is understood  that dilution of ownership can be expected to result
from  that,  and that all such  dilution  will be  ratable;  that is,  all three
initial  owners  interests  will be diluted by some  equal  percentage  of their
initial ownership.  For example, if another party acquired a 50% interest in the
project, the ownership by each of the initial owners would be cut in half.

4. It is agreed  that  patents  may be issued  regarding  this  project and that
ownership of such patents shall be assigned to TM Century.

5. The Board believes it is in the interest of the company and its  shareholders
to maintain the services of David Graupner as President of TM Century. While Mr.
Graupner can be expected to apportion  some  percentage  of his time to pursuing
the  Project,  Mr.  Graupner  agrees to limit  that  time such that the  ongoing
operations  of TM  Century,  which he  oversees,  will not  suffer.  It is fully
expected that the Project will  eventually  have its own  leadership and will be
able to  relieve  Mr.  Graupner's  time to  Sold-Rite  in  favor  of TM  Century

                                       1
<PAGE>

operations.  In all cases, Mr. Graupner agrees to not allow any such commitments
to Sold-Rite to adversely affect TM Century operations.

6. The Board  wishes to  maintain  Mr.  Cope's  services  as a TM Century  Board
Member,  and since the interests of all three  initial  owners are fully aligned
perceives no significant  conflict of interest  regarding TM Century's  interest
created by his ownership interest in Sold-Rite.  The Board acknowledges that Mr.
Cope's  role in  Sold-Rite  has been,  and is  expected  to  continue to be as a
contributor and advisor but not as an employee.  Mr. Cope currently  receives no
salary or benefits from either TM Century or Sold-Rite other than options for TM
Century  stock and the ownership in Sold-Rite.  It is  acknowledged  that if Mr.
Cope takes on a more active role in  Sold-Rite,  he will  probably earn a salary
and/or  additional  stock or options in Sold-Rite.  Even then,  since all equity
interests  in  Sold-Rite  would be aligned,  no  conflict  of interest  would be
inherent so long as his Sold-Rite duties would not inhibit his ability to act as
a TM Century  Director.  Nevertheless,  Mr. Cope will  continue to abstain  from
voting as a TM Century  board member on all matters that might create a conflict
or perceived conflict of interest.  Furthermore,  Mr. Cope agrees to resign from
the TM Century board should the TM Century board  request such  resignation  for
any reason whatever.

7. The Board has  received  advice  and an  opinion  letter  from the  Company's
corporate counsel  indicating that the agreement to apportion David Graupner and
Michael Cope a direct share of the Sold-Rite project should not be considered to
be suborning a corporate opportunity, and therefore, so long as the Agreement is
fully disclosed to shareholders,  should not be seen to create undue exposure to
a shareholder suit. The Board intends to fully disclose all relevant information
regarding Sold-Rite ownership or collateral agreements to all relevant entities,
and  believes  that  the  Agreement  is fair to all  parties,  does  not  suborn
corporate  opportunity,  and is in the  best  interest  of TM  Century  and  its
shareholders.

The  Agreement  upon which this  Memorandum of  Understanding  is based shall be
effective July 31, 2002.

THE CREDITS 
 
Section 2.1 LINE OF CREDIT. 
 
        (a) Line of
Credit. Subject to the terms and conditions of this Agreement, Bank hereby agrees to make Advances to, and issue Letters of Credit for the benefit of, Borrower from time to time up to and including the Line of Credit Termination Date, not to
exceed at any time the Maximum Line of Credit Amount (“Line of Credit”), the proceeds of which shall be used for general working capital purposes. Borrower’s obligation to repay Advances under the Line of Credit shall be evidenced by
a promissory note substantially in the form of Exhibit B attached hereto (“Line of Credit Note”), all terms of which are incorporated herein by this reference. 
 
        (b) Limitation on Borrowings. Notwithstanding any
other provision of this Agreement, Designated Usage shall not at any time subsequent to the Borrowing Base Start Date exceed the lesser of (i) the Borrowing Base, as determined by Bank, as of such date or (ii) the Maximum Line of
Credit Amount less the then Effective Amount of the Systems Letter of Credit. 
 
        (c) Borrowing and Repayment. Borrower may from time to time during the term of the Line of Credit borrow, partially or wholly repay its
outstanding borrowings, and reborrow, subject to all of the limitations, terms and conditions contained herein or in the Line of Credit Note; provided, however, that Designated Usage plus the Effective Amount of the Systems
Letter of Credit shall not at any time exceed the Maximum Line of Credit Amount, and Borrower shall immediately repay the amount, if any, by which Designated Usage plus the Effective Amount of the Systems Letter of Credit exceeds the Maximum
Line of Credit Amount. Similarly, Borrower shall immediately repay the amount by which Designated Usage at any time exceeds the maximum amount permitted by the terms of Section 2.1(b). 
 
        (d) Letter
of Credit Subfeature. 
 
  (i) As a subfeature under the Line of Credit, Bank agrees from time to time up to and including the Line of Credit Termination Date to issue standby letters of credit for the account of Borrower (each, a “Letter of
Credit” and collectively, “Letters of Credit”); provided, however, that the form and substance of each Letter of Credit shall be subject to approval by Bank, in its sole discretion, and provided further,
that the aggregate undrawn amount of all outstanding Letters of Credit under this subfeature (including, without limitation, the Systems Letter of Credit) shall not at any time exceed Six Million Dollars 
 

-8- 

 
($6,000,000.00). Each Letter of Credit shall be issued for a term not to exceed three hundred sixty-five (365) days, as designated by Borrower; provided, however, that no Letter of Credit under this subfeature shall
have an expiration date subsequent to May 29, 2004 unless otherwise approved by Bank. 
 
  (ii) The undrawn amount of all Letters of Credit under this subfeature shall be reserved under the Line of
Credit and shall not be available for Advances thereunder. Each Letter of Credit shall be subject to the additional terms and conditions of the Letter of Credit Agreement and related documents, if any, required by Bank in connection with the
issuance of such Letter of Credit (each individually, a “Letter of Credit Agreement” and collectively, “Letter of Credit Agreements”). Each draft paid by Bank under a Letter of Credit under this subfeature (including under the
“Existing Letters of Credit”, as such term is defined below) shall be deemed an Advance under the Line of Credit and shall repaid in accordance with the terms and conditions of this Agreement applicable to such Advances; provided,
however, that if the Line of Credit is not available, for any reason whatsoever, at the time any draft is paid by Bank, or if Advances are not available under the Line of Credit at such time due to any limitation on borrowings set forth
herein, then the full amount of such draft shall be immediately due and payable, together with interest thereon, from the date such amount is paid by Bank to the date such amount is fully repaid by Borrower at the rate of interest applicable to
Advances under the Line of Credit. In such event Borrower agrees that Bank, in its sole discretion, may debit any demand deposit account maintained by Borrower with Bank for the amount of any draft. As of the Effective Date, the outstanding undrawn
amount of the Systems Letter of Credit is $2,698,596, and there are other Letters of Credit outstanding having an aggregate Effective Amount of $333,293.77 (as identified on Schedule 2.1(d) hereto) (collectively, the “Existing Letters of
Credit”); however, there are no outstanding drafts or Advances paid under this subfeature by Bank. The face amount of the Existing Letters of Credit shall be deemed to be outstanding under this subfeature subject to all terms and conditions
applicable hereto. 
 
  (iii) Borrower agrees that Bank may notify any beneficiary of a Letter of Credit of the occurrence of an Event of Default. In addition, Borrower agrees that upon the occurrence of an Event of Default, Bank may request
that the Systems Trustee accelerate the Systems Bonds. 
 
  (iv) (a) Borrower agrees to cause Systems to make an optional redemption of the Systems Bonds under Section 310(d) of the Loan and Trust Agreement on the Interest Payment Date (as defined in the Loan and Trust
Agreement) occurring on the first Business Day (as defined in the Loan and Trust Agreement) of each of the following calendar months (provided that the Systems Letter of Credit is outstanding on each such date and provided further that each such
optional redemption is permitted under the Loan and Trust Agreement), in

an amount equal to 50 basis points in excess of the then applicable interest rate payable pursuant to the Loan and Trust Agreement on the Systems Bonds which are not Borrower Bonds (as defined in the Loan and Trust Agreement) or Bank Bonds (as

Section 2.2 LIMITATION ON BORROWINGS. With respect to Section 2.1(b), Borrower acknowledges that Bank may from time to time subsequent to the Borrowing Base Start Date, in its sole and absolute discretion, (i) establish
such reserves against the various components of the Borrowing Base as Bank deems necessary and proper and (ii) increase or decrease the percentage applicable to the Eligible Receivables Component. Without in any way limiting the foregoing, Borrower

WAIVER. Any decision by Bank not to require payment of any interest (including default interest), fee, cost or other amount payable under any “Loan Document” (as defined below) upon any occasion shall in no way limit or be deemed a

Upon the occurrence of any Event of Default: (a) all indebtedness of Borrower under each of the Loan Documents, any term thereof to the contrary notwithstanding, shall at Bank’s option and without notice become immediately due and payable
without presentment, demand, protest or notice of dishonor, all of which are hereby expressly waived by Borrower; (b) the obligation, if any, of Bank to extend any further credit under any of the Loan Documents shall immediately cease and terminate;
and (c) Bank shall have all rights, powers and remedies available under each of the Loan Documents, or accorded by law, including the right to resort to any or all security for the Line of Credit and to exercise any or all of the rights of a
beneficiary or secured party pursuant to applicable law. In addition, Bank shall have no obligation to permit further borrowings hereunder if Borrower fails to pay when due any principal, interest, fees or other amounts payable under any of the Loan
Documents, notwithstanding that an Event of Default has not yet occurred under Section 6.1(a) above. All rights, powers and remedies of Bank may be exercised at any time by Bank and from time to time after the occurrence of an Event of
Default, are cumulative and not exclusive, and shall be in addition to any other rights, powers or remedies provided by law or equity. 
 
ARTICLE 8 
MISCELLANEOUS 
 
Section 8.1

any such right, power or remedy preclude, waive or otherwise affect any other or further exercise thereof or the exercise of any other right, power or remedy. Any waiver, permit, consent or approval of any kind by Bank of any breach of or default
under any of the Loan Documents must be in writing and shall be effective only to the extent set forth in such writing.

attorneys and employees (collectively, the “Indemnitees”) from and against: (a) Any and all claims, demands, actions or causes of action that are asserted against any Indemnitee if the claim, demand, action or cause of action arises out of
or relates to the relationship between Borrower and Bank under any of the Loan Documents or the transactions contemplated thereby; (b) Any and all administrative or investigative proceedings by any governmental agency or authority arising out of or
related to any claim, demand, action or cause of action described in clause (a) above; and (c) Any and all liabilities,

professional services) that any Indemnitee suffers or incurs as a result of the assertion of any of the foregoing; provided that no Indemnitee shall be entitled to indemnification for any loss caused by its own or its employees’ or
agents’ gross negligence or willful misconduct. Each Indemnitee is authorized to employ counsel in enforcing its rights hereunder and in defending against any claim, demand, action, cause of action or administrative or investigative proceeding
covered by this Section 8.11; provided that the Indemnitees as a group may retain only one law firm to represent them with respect to any such matter unless there is, under applicable standards of professional conduct, conflict on any
significant issue between the positions of any two or more Indemnitees. Any obligation or liability of Borrower to any Indemnitee under this Section 8.11 shall be and hereby is covered and secured by the Loan Documents and the Collateral
referred to in Section 2.7 and shall survive the expiration or termination of this Agreement and the repayment of the Line of Credit and the payment and performance of all other obligations owed to Bank. 
 
Section 8.12 NONLIABILITY OF BANK. Borrower
acknowledges and agrees that: 
 
(a) Any
inspections of Collateral made by Bank are for purposes of administration of the Line of Credit only and Borrower is not entitled to rely upon the same; 
 
(b) By accepting or approving anything required to be observed, performed, fulfilled or given to Bank pursuant to the Loan Documents,
including any certificate, financial statement, insurance policy or other document, Bank shall not be deemed to have warranted or represented the sufficiency, legality, effectiveness or legal effect of the same, or of any term, provision or
condition thereof, and such acceptance or approval thereof shall not constitute a warranty or representation to anyone with respect thereto by Bank; 
 
(c) The relationship between Borrower and Bank in connection with this Agreement and the other Loan Documents is, and shall at all times
remain, solely that of a borrower and lender; Bank shall not under any circumstance be construed to be a partner or joint venturer of Borrower; Bank shall not under any circumstances be deemed to be in a relationship of confidence or trust or a
fiduciary relationship with Borrower, or to owe any fiduciary duty to Borrower as a result of the transactions arising under this Agreement and the other Loan Documents; Bank does not undertake or assume any responsibility or duty to Borrower to
select, review, inspect, supervise, pass judgment upon or inform Borrower of any matter in connection with its property, any Collateral held by Bank or the operations of Borrower; Borrower shall rely entirely upon its own judgment with respect to
such matters; and any review, inspection, supervision, exercise of judgment or supply of information undertaken or assumed by Bank in connection with such matters is solely for the protection of Bank and neither Borrower nor any other person or
entity is entitled to rely thereon; and 
 
(d) Bank
shall not be responsible or liable to any person or entity for any loss, damage, liability or claim of any kind relating to injury or death to persons or damage to property caused by the actions, inaction or negligence of Borrower and Borrower
hereby indemnifies and 
 

-28- 

holds Bank harmless from any such loss, damage, liability or claim. 
 
Section 8.13 FURTHER ASSURANCES. Borrower shall, at its
expense and without expense to Bank, do, execute and deliver such further acts and documents as Bank from time to time reasonably requires for the assuring and confirming unto Bank of the rights hereby created or intended now or hereafter so to be,
or for carrying out the intention or facilitating the performance of the terms of any Loan Document, or for assuring the validity, perfection, priority or enforceability of any Lien under any Loan Document. 
 
Section 8.14 CONFLICTING PROVISIONS. The provisions of
this Agreement are not intended to supersede the provisions of the other Loan Documents but shall be construed as supplemental thereto. However, in the event of any actual irreconcilable conflict between the provisions hereof and any
provisions of the other Loan Documents, it is intended that the provisions of this Agreement shall control; provided that the inclusion of provisions in such other Loan Documents which are not addressed in this Agreement shall not be deemed a
conflict with this Agreement. The foregoing shall apply with respect to all Loan Documents, whether executed and delivered by Borrower or by any third-party. 
 
Section 8.15 CONTINUED EXISTING EFFECTIVENESS OF CERTAIN EXISTING LOAN DOCUMENTS. Each of the Existing Loan Documents (other
than the Existing Credit Agreement, Existing Note and any other Existing Loan Document that has been (or will be) expressly superseded, replaced or otherwise restated by a “Loan Document”, either as previously executed in connection
with a prior amendment or as executed in connection herewith) shall continue in full force and effect and shall, as of the effective date hereof, be deemed to be a “Loan Document” as such term is used and defined in this Agreement.

 
Section 8.16 ARBITRATION. 
 
(a) Arbitration. The parties hereto agree, upon demand
by any party, to submit to binding arbitration all claims, disputes and controversies between or among them (and their respective employees, officers, directors, attorneys, and other agents), whether in tort, contract or otherwise arising out of or
relating to in any way (i) the loan and related Loan Documents which are the subject of this Agreement and its negotiation, execution, administration, repayment, modification, extension, substitution, formation, inducement, enforcement, default or
termination; or (ii) requests for additional credit. 
 
(b Governing Rules. Any arbitration proceeding will (i) proceed in a location in Los Angeles, California selected by the American Arbitration Association (“AAA”); (ii) be governed by the Federal Arbitration
Act (Title 9 of the United States Code), notwithstanding any conflicting choice of law provision in any of the documents between the parties; and (iii) be conducted by the AAA, or such other administrator as the parties shall mutually agree upon, in
accordance with the AAA’s commercial dispute resolution procedures, unless the claim or counterclaim is at least $1,000,000.00 exclusive of claimed interest, arbitration fees and costs in which case the arbitration shall be conducted in
accordance with the AAA’s optional procedures 
 

-29- 

for large, complex commercial disputes (the commercial dispute resolution procedures or the optional
procedures for large, complex commercial disputes to be referred to, as applicable, as the “Rules”). If there is any inconsistency between the terms hereof and the Rules, the terms and procedures set forth herein shall control. Any
party who fails or refuses to submit to arbitration following a demand by any other party shall bear all costs and expenses incurred by such other party in compelling arbitration of any dispute. Nothing contained herein shall be deemed to be a
waiver by any party that is a bank of the protections afforded to it under 12 U.S.C. §91 or any similar applicable state law. 
 
(c No Waiver of Provisional Remedies. The arbitration requirement does not limit the right of any party to obtain provisional or
ancillary remedies before, during or after the pendency of any arbitration proceeding. This exclusion does not constitute a waiver of the right or obligation of any party to submit any dispute to arbitration or reference hereunder. 
 
(d Arbitrator Qualifications and Powers. Any
arbitration proceeding in which the amount in controversy is $5,000,000.00 or less will be decided by a single arbitrator selected according to the Rules, and who shall not render an award of greater than $5,000,000.00. Any dispute in which the
amount in controversy exceeds $5,000,000.00 shall be decided by majority vote of a panel of three arbitrators; provided however, that all three arbitrators must actively participate in all hearings and deliberations. The arbitrator will be a neutral
attorney licensed in the State of California or a neutral retired judge of the state or federal judiciary of California, in either case with a minimum of ten years experience in the substantive law applicable to the subject matter of the dispute to
be arbitrated. The arbitrator will determine whether or not an issue is arbitratable and will give effect to the statutes of limitation in determining any claim. In any arbitration proceeding the arbitrator will decide (by documents only or with a
hearing at the arbitrator’s discretion) any pre-hearing motions which are similar to motions to dismiss for failure to state a claim or motions for summary adjudication. The arbitrator shall resolve all disputes in accordance with the
substantive law of California and may grant any remedy or relief that a court of such state could order or grant within the scope hereof and such ancillary relief as is necessary to make effective any award. The arbitrator shall also have the power
to award recovery of all costs and fees, to impose sanctions and to take such other action as the arbitrator deems necessary to the same extent a judge could pursuant to the Federal Rules of Civil Procedure, the California Rules of Civil Procedure
or other applicable law. Judgment upon the award rendered by the arbitrator may be entered in any court having jurisdiction. The institution and maintenance of an action for judicial relief or pursuit of a provisional or ancillary remedy shall not
constitute a waiver of the right of any party, including the plaintiff, to submit the controversy or claim to arbitration if any other party contests such action for judicial relief. 
 
(e Discovery. In any arbitration proceeding discovery will be permitted in accordance with the Rules.
All discovery shall be expressly limited to matters directly relevant to the dispute being arbitrated and must be completed no later than 20 days before the hearing date and within 180 days of the filing of the dispute with the AAA. Any requests for
an extension of the discovery periods, or any discovery disputes, will be subject to final 
 

-30- 

determination by the arbitrator upon a showing that the request for discovery is essential for the
party’s presentation and that no alternative means for obtaining information is available. 
 
        (f) Class Proceedings and Consolidations. The resolution of any dispute arising pursuant to the terms of this Agreement shall be determined by a
separate arbitration proceeding and such dispute shall not be consolidated with other disputes or included in any class proceeding. 
 
        (g) Payment Of Arbitration Costs And Fees. The arbitrator shall award all costs and
expenses of the arbitration proceeding. 
 
        (h) Miscellaneous. To the maximum extent practicable, the AAA, the arbitrators and the parties shall take all action required to conclude any arbitration proceeding within 180
days of the filing of the dispute with the AAA. No arbitrator or other party to an arbitration proceeding may disclose the existence, content or results thereof, except for disclosures of information by a party required in the ordinary course of its
business or by applicable law or regulation. If more than one agreement for arbitration by or between the parties potentially applies to a dispute, the arbitration provision most directly related to the Loan Documents or the subject matter of the
dispute shall control. This arbitration provision shall survive termination, amendment or expiration of any of the Loan Documents or any relationship between the parties.
