LINE OF CREDIT. Lender agrees to make Advances to Borrower from time to time

Base. Within the foregoing limits, Borrower may borrow, partially or wholly
prepay, and reborrow under this Agreement as follows.

         Conditions Precedent to Each Advance. Lender's obligation to make any
         Advance to or for the account of Borrower under this Agreement is
         subject to the following conditions precedent, with all documents,
         instruments, opinions, reports, and other items required under this
         Agreement to be in form and substance satisfactory to Lender:

                  (a) Lender shall have received evidence that this Agreement
                  and all Related Documents have been duly authorized, executed,
                  and delivered by Borrower to Lender.

                  (b) Lender shall have received such opinions of counsel,
                  supplemental opinions, and documents as Lender may request.

                  (c) The security interests in the Collateral shall have been
                  duly authorized, created, and perfected with first lien
                  priority and shall be in full force and effect.

                  (d) All guaranties required by Lender for the Line of Credit
                  shall have been executed by each Guarantor, delivered to
                  Lender, and be in full force and effect.

                  (e) Lender, at its option and for its sole benefit, shall have
                  conducted an audit of Borrower's Accounts, books, records, and
                  operations, and Lender shall be satisfied as to their
                  condition.

                  (f) Borrower shall have paid to Lender all fees, costs, and
                  expenses specified in this Agreement and the Related Documents
                  as are then due and payable.

                  (g) There shall not exist at the time of any Advance a
                  condition which would constitute an Event of Default under
                  this Agreement, and Borrower shall have delivered to Lender
                  the compliance certificate called for in the paragraph below
                  titled "Compliance Certificate."

         Making Loan Advances. Advances under the Line of Credit may be
         requested orally by authorized persons. Lender may, but need not,
         require that all oral requests be confirmed in writing. Each Advance
         shall be conclusively deemed to have been made at the request of and
         for the benefit of Borrower (a) when credited to any deposit account of
         Borrower maintained with Lender or (b) when advanced in accordance with
         the instructions of an authorized person. Lender, at its option, may
         set a cutoff time, after which all requests for Advances will be
         treated as having been requested on the next succeeding Business Day.

         Mandatory Loan Repayments. If at any time the aggregate principal
         amount of the outstanding Advances shall exceed the applicable
         Borrowing Base, Borrower, immediately upon written or oral notice from
         Lender, shall pay to Lender an amount equal to the difference between
         the outstanding principal balance of the Advances and the Borrowing
         Base. On the Expiration Date, Borrower shall pay to Lender in full the
         aggregate unpaid principal amount of all Advances then outstanding and
         all accrued unpaid interest, together with all other applicable fees,
         costs and charges, if any, not yet paid.

         Loan Account. Lender shall maintain on its books a record of account in
         which Lender shall make entries for each Advance and such other debits
         and credits as shall be appropriate in connection with the credit
         facility. Lender shall provide Borrower with periodic statements of
         Borrower's account, which statements shall be considered to be correct
         and conclusively binding on Borrower unless Borrower notifies Lender to
         the contrary within thirty (30) days after Borrower's receipt of any
         such statement which Borrower deems to be incorrect.

COLLATERAL. To secure payment of the Line of Credit and performance of all other
Loans, obligations and duties owed by Borrower to Lender, Borrower (and others,
if required) shall grant to Lender Security Interests in such property and
assets as Lender may require (the "Collateral"), including without limitation
Borrower's present and future Accounts and general intangibles. Lender's
Security Interests in the Collateral shall be continuing liens and shall include
the proceeds and products of the Collateral, including without limitation the
proceeds of any insurance. With respect to the Collateral, Borrower agrees and
represents and warrants to Lender:

         Perfection of Security Interests. Borrower agrees to execute such
         financing statements and to take whatever other actions are requested
         by Lender to perfect and continue Lender's Security Interests in the
         Collateral. Upon request of Lender, Borrower will deliver to Lender any
         and all of the documents evidencing or constituting the Collateral, and
         Borrower will note Lender's interest upon any and all chattel paper if
         not delivered to Lender for possession by Lender. Contemporaneous with
         the execution of this Agreement, Borrower will execute one or more UCC
         financing statements and any similar statements as may be required by
         applicable law, and will file such financing statements and all such
         similar statements in the appropriate location or locations. Upon the
         occurrence of any event of default, Borrower hereby appoints Lender as
         its irrevocable attorney-in-fact for the purpose of executing any
         documents necessary to perfect or to continue any Security Interest.
         Lender may at any time, and without further authorization from
         Borrower, file a carbon, photograph, facsimile, or other reproduction
         of any financing statement for use as a financing statement. Borrower
         will reimburse Lender for all expenses for the perfection, termination,
         and the continuation of the perfection of Lender's security interest in
         the Collateral. Borrower promptly will notify Lender of any change in
         Borrower's name including any change to the assumed business names of
         Borrower. Borrower also promptly will notify Lender of any change in
         Borrower's Social Security Number or Employer Identification Number.
         Borrower further agrees to notify Lender in writing prior to any change
         in address or location of Borrower's principal governance office or
         should Borrower merge or consolidate with any other entity.

         Collateral Records. Borrower does now, and at all times hereafter
         shall, keep correct and accurate records of the Collateral, all of
         which records shall be available to Lender or Lender's representative
         upon demand for inspection and copying at any reasonable time. With
         respect to the Accounts, Borrower agrees to keep and maintain such
         records as Lender may require, including without limitation information
         concerning Eligible Accounts and Account balances and agings.

         Collateral Schedules. Concurrently with the execution and delivery of
         this Agreement, Borrower shall execute and deliver to Lender a schedule
         of Accounts and Eligible Accounts, in form and substance satisfactory
         to the Lender. Thereafter Borrower shall execute and deliver to Lender
         such supplemental schedules of Eligible Accounts and such other matters
         and information relating to Borrower's Accounts as Lender may request.
         Supplemental schedules shall be delivered according to the following
         schedule: EVERY 30 DAYS.

         Representations and Warranties Concerning Accounts. With respect to the
         Accounts, Borrower represents and warrants to Lender: (a) Each Account

         Agreement conforms to the requirements of the definition of an Eligible

         Lender will be true and correct, subject to immaterial variance; and
         (c) Lender, its assigns, or agents shall have the right at any time and
         at Borrower's expense to inspect, examine, and audit Borrower's records
         and to confirm with Account Debtors the accuracy of such Accounts.

         Notification Basis. Borrower agrees and understands that this Loan
         shall be on a notification basis pursuant to which Lender shall
         directly collect and receive all proceeds and payments from the
         Accounts in which Lender has a security interest. In order to
         facilitate the foregoing, upon the occurrence of an event of default,
         Borrower agrees to deliver to Lender, upon demand, any and all of
         Borrower's records, ledger sheets, payment cards, and other
         documentation, in the form requested by Lender, with regard to

         the Accounts. Upon the occurrence of an event of default, Borrower
         further agrees that Lender shall have the right to notify each Account
         Debtor, pay such proceeds and payments directly to Lender, and to do
         any and all other things as Lender may deem to be necessary and
         appropriate, within its sole discretion, to carry out the terms and
         intent of this Agreement. Lender shall have the further right, where

         agrees that Lender may take such other actions, either in Borrower's
         name or Lender's name, as Lender may deem appropriate within its sole
         judgment, with regard to collection and payment of the Accounts,
         without affecting the liability of Borrower under this Agreement or on
         the Indebtedness.

         Remittance Account. Borrower agrees that Lender may at any time require
         Borrower to institute procedures whereby the payments and other
         proceeds of the Accounts shall be paid by the Account Debtors under a
         remittance account or lock box arrangement with Lender, or Lender's
         agent, or with one or more financial institutions designated by Lender.
         Borrower further agrees that, if no Event of Default exists under this
         Agreement, any and all of such funds received under such a remittance
         account or lock box arrangement shall, at Lender's sole election and
         discretion, either be (a) paid or turned over to Borrower; (b)
         deposited into one or more accounts for the benefit of Borrower (which
         deposit accounts shall be subject to a security assignment in favor of
         Lender); (c) deposited into one or more accounts for the joint benefit
         of Borrower and Lender (which deposit accounts shall likewise be
         subject to a security assignment in favor of Lender); (d) paid or
         turned over to Lender to be applied to the Indebtedness in such order
         and priority as Lender may determine within its sole discretion; or (e)
         any combination of the foregoing as Lender shall determine from time to
         time. Borrower further agrees that, should one or more Events of
         Default exist, any and all funds received under such a remittance
         account or lock box arrangement shall be paid or turned over to Lender
         to be applied to the Indebtedness, again in such order and priority as
         Lender may determine within its sole discretion.

and at all times any Indebtedness exists:

         validly existing, and in good standing under the laws of the State of

         proposes to engage. Borrower also is duly qualified as a foreign

         financial condition.

         Authorization. The execution, delivery, and performance of this
         Agreement and all Related Documents by Borrower, to the extent to be

         approval of any other person, regulatory authority or governmental
         body; and do not conflict with, result in a violation of, or constitute
         a default under (a) any provision of its articles of incorporation or
         organization, or bylaws, or any agreement or other instrument binding

         Financial Information. Each financial statement of Borrower supplied to
         Lender truly and completely disclosed Borrower's financial condition as
         of the date of the statement, and there has been no material adverse
         change in Borrower's financial condition subsequent to the date of the
         most recent financial statement supplied to Lender. Borrower has no
         material contingent obligations except as disclosed in such financial
         statements.

         title to all of Borrower's properties free and clear of all Security

         Borrower's legal name, and Borrower has not used, or filed a financing
         statement under, any other name for at least the last five (5) years.

         Hazardous Substances. The terms "hazardous waste," "hazardous
         substance," "disposal," "release," and "threatened release," as used in
         this Agreement, shall have the same meanings as set forth in the
         "CERCLA," "SARA," the Hazardous Materials Transportation Act, 49 U.S.C.
         Section 1801, et seq., the Resource Conservation and Recovery Act, 42

         laws, rules, or regulations adopted pursuant to any of the foregoing.
         Except as disclosed to and acknowledged by Lender in writing, Borrower
         represents and warrants that: (a) During the period of Borrower's
         ownership of the properties, there has been no use, generation,
         manufacture, storage, treatment, disposal, release or threatened
         release of any hazardous waste or substance by any person on, under,
         about or from any of the properties. (b) Borrower has no knowledge of,
         or reason to believe that there has been (i) any use, generation,
         manufacture, storage, treatment, disposal, release, or threatened
         release of any hazardous waste or substance on, under, about or from
         the properties by any prior owners or occupants of any of the
         properties, or (ii) any actual or threatened litigation or claims of
         any kind by any person relating to such matters. (c) Neither Borrower
         nor any tenant, contractor, agent or other authorized user of any of
         the properties shall use, generate, manufacture, store, treat, dispose
         of, or release any hazardous waste or substance on, under, about or
         from any of the properties; and any such activity shall be conducted in
         compliance with all applicable federal, state, and local laws,
         regulations, and ordinances, including without limitation those laws,
         regulations and ordinances described above. Borrower authorizes Lender
         and its agents to enter upon the properties to make such inspections
         and tests as Lender may deem appropriate to determine compliance of the
         properties with this section of the Agreement. Any inspections or tests
         made by Lender shall be at Borrower's expense and for Lender's purposes
         only and shall not be construed to create any responsibility or
         liability on the part of Lender to Borrower or to any other person. The
         representations and warranties contained herein are based on Borrower's
         due diligence in investigating the properties for hazardous waste and
         hazardous substances. Borrower hereby (a) releases and waives any
         future claims against Lender for indemnity or contribution in the event
         Borrower becomes liable for cleanup or other costs under any such laws,
         and (b) agrees to indemnify and hold harmless Lender against any and
         all claims, losses, liabilities, damages, penalties, and expenses which
         Lender may directly or indirectly sustain or suffer resulting from a
         breach of this section of the Agreement or as a consequence of any use,
         generation, manufacture, storage, disposal, release or threatened
         release of a hazardous waste or substance on the properties. The
         provisions of this section of the Agreement, including the obligation
         to indemnify, shall survive the payment of the Indebtedness and the
         termination or expiration of this Agreement and shall not be affected
         by Lender's acquisition of any interest in any of the properties,
         whether by foreclosure or otherwise.

         administrative proceeding or similar action (including those for unpaid
         taxes) against Borrower is pending or threatened, and no other event
         has occurred which may materially adversely affect Borrower's financial
         condition or properties, other than litigation, claims, or other
         events, if any, that have been disclosed to and acknowledged by Lender
         in writing.

         of Borrower that are or were required to be filed, have been filed, and
         all taxes, assessments and other governmental charges have been paid in
         full, except those presently being or to be contested by Borrower in
         good faith in the ordinary course of business and for which adequate
         reserves have been provided.

         Lien Priority. Except for permitted liens or otherwise previously
         disclosed to Lender in writing, Borrower has not entered into or

         Insolvency. The dissolution or termination of Borrower's existence as a
         going business, the insolvency of Borrower, the appointment of a
         receiver for any part of Borrower's property, any assignment for the
         benefit of creditors, any type of creditor workout, or the commencement
         of any proceeding under any bankruptcy or insolvency laws by or against
         Borrower.

         Creditor or Forfeiture Proceedings. Commencement of foreclosure or
         forfeiture proceedings, whether by judicial proceeding, self-help,
         repossession or any other method, by any creditor of Borrower, any
         creditor of any Grantor against any collateral securing the
         Indebtedness, or by any governmental agency. This includes a
         garnishment, attachment, or levy on or of any of Borrower's deposit
         accounts with Lender. However, this Event of Default shall not apply if
         there is a good faith dispute by Borrower or Grantor, as the case may
         be, as to the validity or reasonableness of the claim which is the
         basis of the creditor or forfeiture proceeding, and if Borrower or
         Grantor gives Lender written notice of the creditor or forfeiture
         proceeding and furnishes reserves or a surety bond for the creditor or
         forfeiture proceeding satisfactory to Lender.

         Change In Ownership. Any person or entity acquires ownership of
         twenty-five percent (25%) or more of the common stock of Borrower.

         Adverse Change. A material adverse change occurs in Borrower's
         financial condition, or Lender believes the prospect of payment or
         performance of the Indebtedness is impaired.

         Insecurity. Lender, in good faith, deems itself insecure.

         Right to Cure. If any default, other than a Default on Indebtedness, is
         curable, it may be cured (and no Event of Default will have occurred)
         if Borrower or Grantor, as the case may be, after receiving written
         notice from Lender demanding cure of such default: (a) cures the
         default within thirty (30) days; or (b) if the cure requires more than
         thirty (30) days, immediately initiates steps which Lender deems in
         Lender's sole discretion to be sufficient to cure the default and
         thereafter continues and completes all reasonable and necessary steps
         sufficient to produce compliance as soon as reasonably practical.

EFFECT OF AN EVENT OF DEFAULT. If any Event of Default shall occur and shall
remain uncured, except where otherwise provided in this Agreement or the Related
Documents, all commitments and obligations of Lender under this Agreement or the
Related Documents or any other agreement immediately will terminate (including
any obligation to make Loan Advances or disbursements), and, at Lender's option,
all Indebtedness immediately will become due and payable, all without notice of
any kind to Borrower, except that in the case of an Event of Default of the type
described in the "Insolvency" subsection above, such acceleration shall be
automatic and not optional. In addition, Lender shall have all the rights and
remedies provided in the Related Documents or available at law, in equity, or
otherwise. Except as may be prohibited by applicable law, all of Lender's rights
and remedies shall be cumulative and may be exercised singularly or
concurrently. Election by Lender to pursue any remedy shall not exclude pursuit
of any other remedy, and an election to make expenditures or to take action to
perform an obligation of Borrower or of any Grantor shall not affect Lender's
right to declare a default and to exercise its rights and remedies.

MISCELLANEOUS PROVISIONS. The following miscellaneous provisions are a part of
this Agreement:

         Amendments. This Agreement, together with any Related Documents,
         constitutes the entire understanding and agreement of the parties as to
         the matters set forth in this Agreement. No alteration of or amendment
         to this Agreement shall be effective unless given in writing and signed
         by the party or parties sought to be charged or bound by the alteration
         or amendment.

         Applicable Law. This Agreement has been delivered to Lender and
         accepted by Lender in the State of Utah. If there is a lawsuit,
         Borrower agrees upon Lender's request to submit to the jurisdiction of
         the courts of SALT LAKE County, the State of Utah. Subject to the
         provisions on arbitration, this Agreement shall be governed by and
         construed in accordance with the laws of the State of Utah.

<PAGE>

         5.       A PANEL OF ARBITRATORS MIGHT INCLUDE AN ARBITRATOR WHO IS OR
                  WAS AFFILIATED WITH THE BANKING INDUSTRY.

         6.       IF YOU HAVE QUESTIONS ABOUT ARBITRATION, CONSULT YOUR ATTORNEY
                  OR THE AMERICAN ARBITRATION ASSOCIATION.

         (a) Any claim or controversy ("Dispute") between or among the parties
         and their assigns, including but not limited to Disputes arising out of
         or relating to this agreement, this arbitration provision ("arbitration
         clause"), or any related agreements or instruments relating hereto or
         delivered in connection herewith ("Related Documents"), and including
         but not limited to a Dispute based on or arising from an alleged tort,
         shall at the request of any party be resolved by binding arbitration in
         accordance with the applicable arbitration rules of the American
         Arbitration Association (the "Administrator"). The provisions of this
         arbitration clause shall survive any termination, amendment, or
         expiration of this agreement or Related Documents. The provisions of
         this arbitration clause shall supersede any prior arbitration agreement
         between or among the parties. If any provision of this arbitration
         clause should be determined to be unenforceable, all other provisions
         of this arbitration clause shall remain in full force and effect.

         (b) The arbitration proceedings shall be conducted in Salt Lake City,
         Utah, at a place to be determined by the Administrator. The
         Administrator and the arbitrator(s) shall have the authority to the
         extent practicable to take any action to require the arbitration
         proceeding to be completed and the arbitrator(s)' award issued within
         one hundred fifty (150) days of the filing of the Dispute with the
         Administrator. The arbitrator(s) shall have the authority to impose
         sanctions on any party that fails to comply with time periods imposed
         by the Administrator or the arbitrator(s), including the sanction of
         summarily dismissing any Dispute or defense with prejudice. The
         arbitrator(s) shall have the authority to resolve any Dispute regarding
         the terms of this agreement, this arbitration clause or Related
         Documents, including any claim or controversy regarding the
         arbitrability of any Dispute. All limitations periods applicable to any
         Dispute or defense, whether by statute or agreement, shall apply to any
         arbitration proceeding hereunder and the arbitrator(s) shall have the
         authority to decide whether any Dispute or defense is barred by a
         limitations period and, if so, to summarily enter an award dismissing
         any Dispute or defense on that basis. The doctrines of compulsory
         counterclaim, res judicata, and collateral estoppel shall apply to any
         arbitration proceeding hereunder so that a party must state as a
         counterclaim in the arbitration proceeding any claim or controversy
         which arises out of the transaction or occurrence that is the subject
         matter of the Dispute. The arbitrator(s) may in the arbitrator(s)'
         discretion and at the request of any party: (1) consolidate in a single
         arbitration proceeding any other claim or controversy involving another
         party that is substantially related to the Dispute where that other
         party is bound by an arbitration clause with the Lender, such as
         borrowers, guarantors, sureties, and owners of collateral; (2)
         consolidate in a single arbitration proceeding any other claim or
         controversy that is substantially similar to the Dispute; and (3)
         administer multiple arbitration claims or controversies as class
         actions in accordance with the provisions of Rule 23 of the Federal
         Rules of Civil Procedure.

         (c) The arbitrator(s) shall be selected in accordance with the rules of
         the Administrator from panels maintained by the Administrator. A single
         arbitrator shall have expertise in the subject matter of the Dispute.
         Where three arbitrators conduct an arbitration proceeding, the Dispute
         shall be decided by a majority vote of the three arbitrators, at least
         one of whom must have expertise in the subject matter of the Dispute
         and at least one of whom must be a practicing attorney. The
         arbitrator(s) shall award to the prevailing party recovery of all costs
         and fees (including attorneys' fees and costs, arbitration
         administration fees and costs, and arbitrator(s)' fees). The
         arbitrator(s), either during the pendency of the arbitration proceeding
         or as part of the arbitration award, also may grant provisional or
         ancillary remedies, including but not limited to an award of injunctive
         relief, foreclosure, sequestration, attachment, replevin, garnishment,
         or the appointment of a receiver.

         (d) Judgment upon an arbitration award may be entered in any court
         having jurisdiction, subject to the following limitation: the
         arbitration award is binding upon the parties only if the amount does
         not exceed Four Million Dollars ($4,000,000.00); if the award exceeds
         that limit, either party may demand the right to a court trial. Such a
         demand must be filed with the Administrator within thirty (30) days
         following the date of the arbitration award; if such a demand is not
         made within that time period, the amount of the arbitration award shall
         be binding. The computation of the total amount of an arbitration award
         shall include amounts awarded for attorneys' fees and costs,
         arbitration administration fees and costs, and arbitrator(s)' fees.

         (e) No provision of this arbitration clause, nor the exercise of any
         rights hereunder, shall limit the right of any party to: (1) judicially
         or non-judicially foreclose against any real or personal property
         collateral or other security; (2) exercise self-help remedies,
         including but not limited to repossession and setoff rights; or (3)
         obtain from a court having jurisdiction thereover any provisional or
         ancillary remedies, including but not limited to injunctive relief,
         foreclosure, sequestration, attachment, replevin, garnishment, or the
         appointment of a receiver. Such rights can be exercised at any time,
         before or during initiation of an arbitration proceeding, except to the
         extent such action is contrary to the arbitration award. The exercise
         of such rights shall not constitute a waiver of the right to submit any
         Dispute to arbitration, and any claim or controversy related to the
         exercise of such rights shall be a Dispute to be resolved under the
         provisions of this arbitration clause. Any party may initiate
         arbitration with the Administrator; however, if any party initiates
         litigation and another party disputes any allegation in that
         litigation, the disputing party--upon the request of the initiating
         party--must file a demand for arbitration with the Administrator and
         pay the Administrator's filing fee. The parties may serve by mail a
         notice of an initial motion for an order of arbitration.

         (f) Notwithstanding the applicability of any other law to this
         agreement, the arbitration clause, or Related Documents between or
         among the parties, the Federal Arbitration Act, 9 U.S.C. Section 1 et
         seq., shall apply to the construction and interpretation of this
         arbitration clause.

         Caption Headings. Caption headings in this Agreement are for
         convenience purposes only and are not to be used to interpret or define
         the provisions of this Agreement.

         Consent to Loan Participation. Borrower agrees and consents to Lender's
         sale or transfer, whether now or later, of one or more participation
         interests in the Loans to one or more purchasers, whether related or
         unrelated to Lender, provided that Lender must obtain Borrower's prior
         written approval so long as no default is outstanding, which approval
         shall not be unreasonably withheld. Lender may provide, without any
         limitation whatsoever, to any one or more purchasers, or potential
         purchasers, any information or knowledge Lender may have about Borrower
         or about any other matter relating to the Loan, and Borrower hereby
         waives any rights to privacy it may have with respect to such matters.
         Borrower additionally waives any and all notices of sale of
         participation interests, as well as all notices of any repurchase of
         such participation interests. Borrower also agrees that the purchasers
         of any such participation interests will be considered as the absolute
         owners of such interests in the Loans and will have all the rights
         granted under the participation agreement or agreements governing the
         sale of such participation interests. Borrower further waives all
         rights of offset or counterclaim that it may have now or later against
         Lender or against any purchaser of such a participation interest and
         unconditionally agrees that either Lender or such purchaser may enforce
         Borrower's obligation under the Loans irrespective of the failure or
         insolvency of any holder of any interest in the Loans. Borrower further
         agrees that the purchaser of any such participation interests may
         enforce its interests irrespective of any personal claims or defenses
         that Borrower may have against Lender.

         Costs and Expenses. Borrower agrees to pay upon demand all of Lender's
         expenses, including without limitation reasonable attorneys' fees,
         incurred in connection with the preparation, execution, enforcement,
         modification and collection of this Agreement or in connection with the
         Loans made pursuant to this Agreement. Lender may pay someone else to
         help collect the Loans and to enforce this Agreement, and Borrower will
         pay that amount. This includes, subject to any limits under applicable
         law, Lender's

<PAGE>

         reasonable attorneys' fees and Lender's legal expenses, whether or not
         there is a lawsuit, including reasonable attorneys' fees for bankruptcy
         proceedings (including efforts to modify or vacate any automatic stay
         or injunction), appeals, and any anticipated post-judgment collection
         services. Borrower also will pay any court costs, in addition to all
         other sums provided by law.

         Notices. All notices required to be given under this Agreement shall be
         given in writing, may be sent by telefacsimile (unless otherwise
         required by law), and shall be effective when actually delivered or
         when deposited with a nationally recognized overnight courier or
         deposited in the United States mail, first class, postage prepaid,
         addressed to the party to whom the notice is to be given at the address
         shown above. Any party may change its address for notices under this
         Agreement by giving formal written notice to the other parties,
         specifying that the purpose of the notice is to change the party's
         address. To the extent permitted by applicable law, if there is more
         than one Borrower, notice to any Borrower will constitute notice to all
         Borrowers. For notice purposes, Borrower will keep Lender informed at
         all times of Borrower's current address(es).

         Severability. If a court of competent jurisdiction finds any provision
         of this Agreement to be invalid or unenforceable as to any person or
         circumstance, such finding shall not render that provision invalid or
         unenforceable as to any other persons or circumstances. If feasible,
         any such offending provision shall be deemed to be modified to be
         within the limits of enforceability or validity; however, if the
         offending provision cannot be so modified, it shall be stricken and all
         other provisions of this Agreement in all other respects shall remain
         valid and enforceable.

         Subsidiaries and Affiliates of Borrower. To the extent the context of
         any covenant of this Agreement makes it appropriate, the word
         "Borrower" as used herein shall include all subsidiaries and affiliates
         of Borrower. Notwithstanding the foregoing however, under no
         circumstances shall this Agreement be construed to require Lender to
         make any Loan or other financial accommodation to any subsidiary or
         affiliate of Borrower.

         Successors and Assigns. All covenants and agreements contained by or on
         behalf of Borrower shall bind its successors and assigns and shall
         inure to the benefit of Lender, its successors and assigns. Borrower
         shall not, however, have the right to assign its rights under this
         Agreement or any interest therein, without the prior written consent of
         Lender.

         Survival. All warranties, representations, and covenants made by
         Borrower in this Agreement or in any certificate or other instrument
         delivered by Borrower to Lender under this Agreement shall be
         considered to have been relied upon by Lender and will survive the
         making of the Loan and delivery to Lender of the Related Documents,
         regardless of any investigation made by Lender or on Lender's behalf.

         Time Is of the Essence. Time is of the essence in the performance of
         this Agreement.

         Waiver. Lender shall not be deemed to have waived any rights under this
         Agreement unless such waiver is given in writing and signed by Lender.
         No delay or omission on the part of Lender in exercising any right
         shall operate as a waiver of such right or any other right. A waiver by
         Lender of a provision of this Agreement shall not prejudice or
         constitute a waiver of Lender's right otherwise to demand strict
         compliance with that provision or any other provision of this
         Agreement. No prior waiver by Lender, nor any course of dealing between
         Lender and Borrower, or between Lender and any Grantor, shall
         constitute a waiver of any of Lender's rights or of any obligations of
         Borrower or of any Grantor as to any future transactions. Whenever the
         consent of Lender is required under this Agreement, the granting of
         such consent by Lender in any instance shall not constitute continuing
         consent in subsequent instances where such consent is required, and in
         all cases such consent may be granted or withheld in the sole
         discretion of Lender.

FINAL AGREEMENT. Borrower understands that this Agreement and the related loan
documents are the final expression of the agreement between Lender and Borrower
and may not be contradicted by evidence of any alleged oral agreement.

BORROWER ACKNOWLEDGES HAVING READ ALL THE PROVISIONS OF THIS LOAN AGREEMENT, AND
BORROWER AGREES TO ITS TERMS. THIS AGREEMENT IS DATED AS OF OOCTOBER 18, 2000.
