BORROWER: MEDAIRE, INC.                          LENDER: DESERT HILLS BANK
          80 EAST RIO SALADO PARKWAY, SUITE 610          3001 E. CAMELBACK ROAD
          TEMPE, AZ 85281                                PHOENIX, AZ 85016

PRINCIPAL AMOUNT:  $1,000,000.00
INITIAL RATE:  6.500%
DATE OF AGREEMENT: APRIL 29, 2005

DESCRIPTION OF EXISTING INDEBTEDNESS. Promissory Note Number 70000105 dated
April 29, 2003 in the original principal amount of $1,000,000.00 to Borrower and
any modifications and/or renewals thereof.

DESCRIPTION OF COLLATERAL. Borrower acknowledges this Note is secured by: (A) A
Commercial Security Agreement dated April 29, 2003.

DESCRIPTION OF CHANGE IN TERMS. The Maturity date is hereby extended from April
29, 2005 to May 2, 2006. The monthly interest payment date is changed from the
29th of each month to the second of each month. The late charge is amended
according to the late charge section. All other terms and conditions shall
remain the same and in full force.

PROMISE TO PAY. MEDAIRE, INC. ("BORROWER") PROMISES TO PAY TO DESERT HILLS BANK
("LENDER"), OR ORDER, IN LAWFUL MONEY OF THE UNITED STATES OF AMERICA, THE
PRINCIPAL AMOUNT OF ONE MILLION & 00/100 DOLLARS ($1,000,000.00) OR SO MUCH AS
MAY BE OUTSTANDING, TOGETHER WITH INTEREST ON THE UNPAID OUTSTANDING PRINCIPAL
BALANCE OF EACH ADVANCE. INTEREST SHALL BE CALCULATED FROM THE DATE OF EACH
ADVANCE UNTIL REPAYMENT OF EACH ADVANCE.

PAYMENT. BORROWER WILL PAY THIS LOAN IN FULL IMMEDIATELY UPON LENDER'S DEMAND.
IF NO DEMAND IS MADE, BORROWER WILL PAY THIS LOAN IN ONE PAYMENT OF ALL
OUTSTANDING PRINCIPAL PLUS ALL ACCRUED UNPAID INTEREST ON MAY 2, 2006. IN
ADDITION, BORROWER WILL PAY REGULAR MONTHLY PAYMENTS OF ALL ACCRUED UNPAID
INTEREST DUE AS OF EACH PAYMENT DATE, BEGINNING JUNE 2, 2005, WITH ALL
SUBSEQUENT INTEREST PAYMENTS TO BE DUE ON THE SAME DAY OF EACH MONTH AFTER THAT.
UNLESS OTHERWISE AGREED OR REQUIRED BY APPLICABLE LAW, PAYMENTS WILL BE APPLIED
FIRST TO ANY ACCRUED UNPAID INTEREST; THEN TO PRINCIPAL; THEN TO ANY LATE
CHARGES; AND THEN TO ANY UNPAID COLLECTION COSTS. INTEREST ON THIS AGREEMENT IS
COMPUTED ON A 365/360 SIMPLE INTEREST BASIS; THAT IS, BY APPLYING THE RATIO OF
THE ANNUAL INTEREST RATE OVER A YEAR OF 360 DAYS, MULTIPLIED BY THE OUTSTANDING
PRINCIPAL BALANCE, MULTIPLIED BY THE ACTUAL NUMBER OF DAYS THE PRINCIPAL BALANCE
IS OUTSTANDING. BORROWER WILL PAY LENDER AT LENDER'S ADDRESS SHOWN ABOVE OR AT
SUCH OTHER PLACE AS LENDER MAY DESIGNATE IN WRITING.

VARIABLE INTEREST RATE. The interest rate on this Agreement is subject to change
from time to time based on changes in an independent index which is the Money
Rate Section of the Western Edition of the Wall Street Journal Prime Rate (the
"Index"). The Index is not necessarily the lowest rate charged by Lender on its
loans. If the Index becomes unavailable during the term of this loan, Lender may
designate a substitute index after notice to Borrower. Lender will tell Borrower
the current Index rate upon Borrower's request. The interest rate change will
not occur more often than each day. Borrower understands that Lender may make
loans based on other rates as well. THE INDEX CURRENTLY IS 5.750% PER ANNUM. THE
INTEREST RATE TO BE APPLIED TO THE UNPAID PRINCIPAL BALANCE OF THE NOTE WILL BE
AT A RATE OF 0.750 PERCENTAGE POINTS OVER THE INDEX, RESULTING IN AN INITIAL
RATE OF 6.500% PER ANNUM. NOTICE: Under no circumstances will the interest rate
on the Note be more than the maximum rate allowed by applicable law.

EFFECTIVE RATE. Borrower agrees to an effective rate of interest that is the
rate specified in this Agreement plus any additional rate resulting from any
other charges in the nature of interest paid or to be paid in connection with
this Agreement.

PREPAYMENT. Borrower may pay without penalty all or a portion of the amount owed
earlier than it is due. Early payments will not, unless agreed to by Lender in
writing, relieve Borrower of Borrower's obligation to continue to make payments
of accrued unpaid interest. Rather, early payments will reduce the principal
balance due. Borrower agrees not to send Lender payments marked "paid in full",
"without recourse", or similar language. If Borrower sends such a payment,
Lender may accept it without losing any of Lender's rights under this Agreement,
and Borrower will remain obligated to pay any further amount owed to Lender. All
written communications concerning disputed amounts, including any check or other
payment instrument that indicates that the payment constitutes "payment in full"
of the amount owed or that is tendered with other conditions or limitations or
as full satisfaction of a disputed amount must be mailed or delivered to: Desert
Hills Bank, Attn: Loan Servicing, 3001 E. Camelback Road Phoenix, AZ 85016.

LATE CHARGE. II a payment is 10 days or more late, Borrower will be charged
5.000% of the unpaid portion of the regularly scheduled payment or $25.00,
whichever is greater.

INTEREST AFTER DEFAULT. Upon default, at Lender's option, and if permitted by
applicable law, Lender may add any unpaid accrued interest to principal and such
sum will bear interest therefrom until paid at the rate provided in this
Agreement (including any increased rate). Upon default, Lender, at its option,
may, if permitted under applicable law, increase the variable interest rate on
this Agreement to 5.750 percentage points over the Index. The interest rate will
not exceed the maximum rate permitted by applicable law.

DEFAULT. Each of the following shall constitute an Event of Default under this
Agreement:

      PAYMENT DEFAULT. Borrower fails to make any payment when due under the
      Indebtedness.

      OTHER DEFAULTS. Borrower fails to comply with or to perform any other
      term, obligation, covenant or condition contained in this Agreement or in
      any of the Related Documents or to comply with or to perform any term,
      obligation, covenant or condition contained in any other agreement between
      Lender and Borrower.

      DEFAULT IN FAVOR OF THIRD PARTIES. Borrower defaults under any loan,
      extension of credit, security agreement, purchase or sales agreement, or
      any other agreement, in favor of any other creditor or person that may
      materially affect any of Borrower's property or Borrower's ability to
      perform Borrower's obligations under this Agreement or any of the Related
      Documents.

      FALSE STATEMENTS. Any warranty, representation or statement made or
      furnished to Lender by Borrower or on Borrower's behalf under this
      Agreement or the Related Documents is false or misleading in any material
      respect, either now or at the time made or furnished or becomes false or
      misleading at any time thereafter.

      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 or by any
      governmental agency against any collateral securing the Indebtedness. This
      includes a garnishment of any of Borrower's accounts, including deposit
      accounts, with Lender. However, this Event of Default shall not apply if
      there is a good faith dispute by Borrower as to the validity or
      reasonableness of the claim which is the basis of the creditor of
      forfeiture proceeding and if Borrower gives Lender written notice of the
      creditor or forfeiture proceeding and deposits with Lender monies or a
      surety bond for the creditor or forfeiture proceeding, in an amount
      determined by Lender, in its sole discretion, as being an adequate reserve
      or bond for the dispute.

      EVENTS AFFECTING GUARANTOR. Any of the preceding events occurs with
      respect to any guarantor, endorser, surety, or accommodation party of any
      of the Indebtedness or any guarantor, endorser, surety, or accommodation
      party dies or becomes incompetent, or revokes or disputes the validity of,
      or liability under, any Guaranty of the Indebtedness evidenced by this
      Note. In the event of a death, Lender, at its option, may, but shall not
      be required to, permit the guarantor's estate to assume unconditionally
      the obligations arising under the guaranty in a manner satisfactory to
      Lender, and, in doing so, cure any Event of Default.

      CHANGE IN OWNERSHIP. Any change in 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 believes itself insecure.

      CURE PROVISIONS. If any default, other than a default in payment is
      curable and if Borrower has not been given a notice of a breach of the
      same provision of this Agreement within the preceding twelve (12) months,
      it may be cured if Borrower, after receiving written notice from Lender
      demanding cure of such default: (1) cures the default within fifteen (15)
      days; or (2) if the cure requires more than fifteen (15) 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.

LENDER'S RIGHTS. Upon default, Lender may declare the entire unpaid principal
balance on this Agreement and all accrued unpaid interest immediately due, and
then Borrower will pay that amount.

ATTORNEYS' FEES; EXPENSES. Lender may hire or pay someone else to help collect
this Agreement if Borrower does not pay. Borrower will pay Lender that amount.
This includes, subject to any limits under applicable law, Lender's attorneys'
fees and Lender's legal expenses, whether or not there is a lawsuit, including
attorneys' fees, expenses for bankruptcy proceedings (including efforts to
modify or vacate any automatic stay or injunction), and appeals. However,
Borrower will only pay attorneys' fees of an attorney not Lender's salaried
employee, to whom the matter is referred after Borrower's default. If not
prohibited by applicable law, Borrower also will pay any court costs, in
addition to all other sums provided by law.

JURY WAIVER. Lender and Borrower hereby waive the right to any jury trial in any
action, proceeding, or counterclaim brought by either Lender or Borrower against
the other.

GOVERNING LAW. This Agreement will be governed by federal law applicable to
Lender and, to the extent not preempted by federal law, the laws of the State of
Arizona without regard to its conflicts of law provisions. This Agreement has
been accepted by Lender in the State of Arizona.

CHOICE OF VENUE. If there is a lawsuit, Borrower agrees upon Lender's request to
submit to the jurisdiction of the courts of MARICOPA County, State of Arizona.

DISHONORED ITEM FEE. Borrower will pay a fee to Lender of $25.00 if Borrower
makes a payment on Borrower's loan and the check or preauthorized charge with
which Borrower pays is later dishonored.

RIGHT OF SETOFF. To the extent permitted by applicable law, Lender reserves a
right of setoff in all Borrower's accounts with Lender (whether checking,
savings, or some other account). This includes all accounts Borrower holds
jointly with someone else and all accounts Borrower may open in the future.
However, this does not include any IRA or Keogh accounts, or any trust accounts
for which setoff would be prohibited by law. Borrower authorizes Lender, to the
extent permitted by applicable law, to charge or setoff all sums owing on the
indebtedness against any and all such accounts, and, at Lender's option, to
administratively freeze all such accounts to allow Lender to protect Lender's
charge and setoff rights provided in this paragraph.

COLLATERAL. Borrower acknowledges this Agreement is secured by A COMMERCIAL
SECURITY AGREEMENT DATED APRIL 29, 2003.

LINE OF CREDIT. This Agreement evidences a revolving line of credit. Advances
under this Agreement may be requested either orally or in writing by Borrower or
as provided in this paragraph. Lender may, but need not, require that all oral
requests be confirmed in writing. All communications, instructions, or
directions by telephone or otherwise to Lender are to be directed to Lender's
office shown above. The following person currently is authorized to request
advances and authorize payments under the line of credit until Lender receives
from Borrower, at Lender's address shown above, written notice of revocation of
his or her authority: JOAN SULLIVAN GARRET, President of MEDAIRE, INC. Borrower
agrees to be liable for all sums either: (A) advanced in accordance with the
instructions of an authorized person or (B) credited to any of Borrower's
accounts with Lender. The unpaid principal balance owing on this Agreement at
any time may be evidenced by endorsements on this Agreement or by Lender's
internal records, including daily computer print-outs. Lender will have no
obligation to advance funds under this Agreement if: (A) Borrower or any
guarantor is in default under the terms of this Agreement or any agreement that
Borrower or any guarantor has with Lender, including any agreement made in
connection with the signing of this Agreement; (B) Borrower or any guarantor
ceases doing business or is insolvent; (C) any guarantor seeks, claims or
otherwise attempts to limit, modify or revoke such guarantor's guarantee of this
Agreement or any other loan with Lender; (D) Borrower has applied funds provided
pursuant to this Agreement for purposes other than those authorized by Lender;
or (E) Lender in good faith believes itself insecure.

CONTINUING VALIDITY. Except as expressly changed by this Agreement, the terms of
the original obligation or obligations, including all agreements evidenced or
securing the obligation(s), remain unchanged and in full force and effect.
Consent by Lender to this Agreement does not waive Lender's right to strict
performance of the obligation(s) as changed, nor obligate Lender to make any
future change in terms. Nothing in this Agreement will constitute a satisfaction
of the obligation(s). It is the intention of Lender to retain as liable parties
all makers and endorsers of the original obligation(s), including accommodation
parties, unless a party is expressly released by Lender in writing. Any maker or
endorser, including accommodation makers, will not be released by virtue of this
Agreement. If any person who signed the original obligation does not sign this
Agreement below, then all persons signing below acknowledge that this Agreement
is given conditionally, based on the representation to Lender that the
non-signing party consents to the changes and provisions of this Agreement or
otherwise will not be released by it. This waiver applies not only to any
initial extension, modification or release, but also to all such subsequent
actions.

SUCCESSORS AND ASSIGNS. Subject to any limitations stated in this Agreement on
transfer of Borrower's interest, this Agreement shall be binding upon and inure
to the benefit of the parties, their successors and assigns. If ownership of the
Collateral becomes vested in a person other than Borrower, Lender, without
notice to Borrower, may deal with Borrower's successors with reference to this
Agreement and the Indebtedness by way of forbearance or extension without
releasing Borrower from the obligations of this Agreement or liability under the
Indebtedness.

MISCELLANEOUS PROVISIONS. This Agreement is payable on demand. The inclusion of
specific default provisions or rights of Lender shall not preclude Lender's
right to declare payment of this Agreement on its demand. Lender may delay or
forgo enforcing any of its rights or remedies under this Agreement without
losing them. Borrower and any other person who signs, guarantees or endorses
this Agreement, to the extent allowed by law, waive presentment, demand for
payment, and notice of dishonor. Upon any change in the terms of this Agreement,
and unless otherwise expressly stated in writing, no party who signs this
Agreement, whether as maker, guarantor, accommodation maker or endorser, shall
be released from liability. All such parties agree that Lender may renew or
extend (repeatedly and for any length of time) this loan or release any party or
guarantor or collateral; or impair, fail to realize upon or perfect Lender's
security interest in the collateral; and take any other action deemed necessary
by Lender without the consent of or notice to anyone. All such parties also
agree that Lender may modify this loan without the consent of or notice to
anyone other than the party with whom the modification is made. The obligations
under this Agreement are joint and several.

PRIOR TO SIGNING THIS AGREEMENT, BORROWER READ AND UNDERSTOOD ALL THE PROVISIONS
OF THIS AGREEMENT, INCLUDING THE VARIABLE INTEREST RATE PROVISIONS. BORROWER

BORROWER: MEDAIRE, INC.                           LENDER: DESERT HILLS BANK
          80 EAST RIO SALADO PARKWAY, SUITE 610           3001 E. CAMELBACK ROAD
          TEMPE, AZ 85281                                 PHOENIX, AZ 85016

THIS BUSINESS LOAN AGREEMENT (ASSET BASED) dated April 29, 2005, is made and
executed between MEDAIRE, INC. ("Borrower") and DESERT HILLS BANK ("Lender") on
the following terms and conditions. Borrower has received prior commercial loans
from Lender or has applied to Lender for a commercial loan or loans or other
financial accommodations, including those which may be described on any exhibit
or schedule attached to this Agreement ("Loan"). Borrower understands and agrees
that: (A) in granting, renewing, or extending any Loan, Lender is relying upon
Borrower's representations, warranties, and agreements as set forth in this
Agreement; (B) the granting, renewing, or extending of any Loan by Lender at all
times shall be subject to Lender's sole judgment and discretion; and (C) all
such Loans shall be and remain subject to the terms and conditions of this
Agreement.

TERM. This Agreement shall be effective as of April 29, 2005, and shall continue
in full force and effect until such time as all of Borrower's Loans in favor of
Lender have been paid in full, including principal, interest, costs, expenses,
attorneys' fees, and other fees and charges, or until such time as the parties
may agree in writing to terminate this Agreement.

LINE OF CREDIT. Lender agrees to make Advances to Borrower from time to time
from the date of this Agreement to the Expiration Date, provided the aggregate
amount of such Advances outstanding at any time does not exceed the Borrowing
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:

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

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

            (3)   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.

            (4)   All Guaranties required by Lender for the credit facility(ies)
                  shall have been executed by each Guarantor, delivered to
                  Lender, and be in full force and effect.

            (5)   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.

            (6)   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.

            (7)   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 this credit facility, as well as
      directions for payment from Borrower's accounts, may be requested orally
      or in writing 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 (1) when credited to any deposit account of Borrower
      maintained with Lender or (2) when advanced in accordance with the
      instructions of an authorized person. Lender, at its option, many 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 Primary Credit Facility 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. 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

      manufacture, storage, treatment, disposal, release or threatened release
      of any Hazardous Substance by any person on, under, about or from any of
      the Collateral. (2) Borrower has no knowledge of, or reason to believe
      that there has been (a) any breach or violation of any Environmental Laws;

      based on Borrower's due diligence in investigating the Collateral for
      hazardous waste and Hazardous Substances. Borrower hereby (1) releases and

      generation, manufacture, storage, disposal, release or threatened release
      of a hazardous waste or substance on the Collateral. The provisions of
      this section of the Agreement, including the obligation to indemnify,
      shall survive the payment of the Indebtedness and the termination,

      foreclosure or otherwise.

      proceeding or similar action (including those for unpaid taxes) against
      Borrower is pending or threatened, and no other event has occurred which

      permitted the filing or attachment of any Security Interests on or
      affecting any of the Collateral directly or indirectly securing repayment
      of Borrower's Loan and Note, that would be prior or that may in any way be
      superior to Lender's Security Interests and rights in and to such
      Collateral.

      BINDING EFFECT. This Agreement, the Note, all Security Agreements (if
      any), and all Related Documents are binding upon the signers thereof, as
      well as upon their successors, representatives and assigns, and are

Guarantor's guaranty of the Loan or any other loan with Lender; or (E) Lender in
good faith deems itself insecure, even though no Event of Default shall have
occurred.

RIGHT OF SETOFF. To the extent permitted by applicable law, Lender reserves a
right of setoff in all Borrower's accounts with Lender (whether checking,
savings, or some other account). This includes all accounts Borrower holds
jointly with someone else and all accounts Borrower may open in the future.
However, this does not include any IRA or Keogh accounts, or any trust accounts
for which setoff would be prohibited by law. Borrower authorizes Lender, to the
extent permitted by applicable law, to charge or setoff all sums owing on the
Indebtedness against any and all such accounts, and, at Lender's option, to
administratively freeze all such accounts to allow Lender to protect Lender's
charge and setoff rights provided in this paragraph.

DEFAULT. Each of the following shall constitute an Event of Default under this
Agreement:

      PAYMENT DEFAULT. Borrower fails to make any payment when due under the
      Loan.

      OTHER DEFAULTS. Borrower fails to comply with or to perform any other
      term, obligation, covenant or condition contained in this Agreement or in
      any of the Related Documents or to comply with or to perform any term,
      obligation, covenant or condition contained in any other agreement between
      Lender and Borrower.

      DEFAULT IN FAVOR OF THIRD PARTIES. Borrower or any Grantor defaults under
      any loan, extension of credit, security agreement, purchase or sales
      agreement, or any other agreement, in favor of any other creditor or
      person that may materially affect any of Borrower's or any Grantor's
      property or Borrower's or any Grantor's ability to repay the Loans or
      perform their respective obligations under this Agreement or any of the
      Related Documents.

      FALSE STATEMENTS. Any warranty, representation or statement made or
      furnished to Lender by Borrower or on Borrower's behalf under this
      Agreement or the Related Documents is false or misleading in any material
      respect, either now or at the time made or furnished or becomes false or
      misleading at any time thereafter.

      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.

      DEFECTIVE COLLATERALIZATION. This Agreement or any of the Related
      Documents ceases to be in full force and effect (including failure of any
      collateral document to create a valid and perfected security interest or
      lien) at any time and for any reason.

      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 or by any
      governmental agency against any collateral securing the Loan. This
      includes a garnishment of any of Borrower's accounts, including deposit
      accounts, with Lender. However, this Event of Default shall not apply if
      there is a good faith dispute by Borrower as to the validity or
      reasonableness of the claim which is the basis of the creditor or
      forfeiture proceeding and if Borrower gives Lender written notice of the
      creditor or forfeiture proceeding and deposits with Lender monies or a
      surety bond for the creditor or forfeiture proceeding, in an amount
      determined by Lender, in its sole discretion, as being an adequate reserve
      or bond for the dispute.

      EVENTS AFFECTING GUARANTOR. Any of the preceding events occurs with
      respect to any Guarantor of any of the Indebtedness or any Guarantor dies
      or becomes incompetent, or revokes or disputes the validity of, or
      liability under, any Guaranty of the Indebtedness. In the event of a
      death, Lender, at its option, may, but shall not be required to, permit
      the Guarantor's estate to assume unconditionally the obligations arising
      under the guaranty in a manner satisfactory to Lender, and, in doing so,
      cure any Event of Default.

      CHANGE IN OWNERSHIP. Any change in 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 Loan is impaired.

      INSECURITY. Lender in good faith believes itself insecure.

      RIGHT TO CURE. If any default, other than a default on Indebtedness, is
      curable and if Borrower or Grantor, as the case may be, has not been given
      a notice of a similar default within the preceding twelve (12) months, it
      may be cured if Borrower or Grantor, as the case may be, after receiving
      written notice from Lender demanding cure of such default: (1) cure the
      default within fifteen (15) days; or (2) if the cure requires more than
      fifteen (15) days, immediately initiate steps which Lender deems in
      Lender's sole discretion to be sufficient to cure the default and
      thereafter continue and complete 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, 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
further 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.

      ATTORNEYS' FEES; EXPENSES. Borrower agrees to pay upon demand all of
      Lender's costs and expenses, including Lender's attorneys' fees and
      Lender's legal expenses, incurred in connection with the enforcement of
      this Agreement. Lender may hire or pay someone else to help enforce this
      Agreement, and Borrower shall pay the costs and expenses of such
      enforcement. Costs and expenses include Lender's attorneys' fees and legal
      expenses whether or not there is a lawsuit, including attorneys' fees and
      legal expenses for bankruptcy proceedings (including efforts to modify or
      vacate any automatic stay or injunction), appeals, and any anticipated
      post-judgment collection services. However, Borrower will only pay
      attorneys' fees of an attorney not Lender's salaried employee, to whom the
      matter is referred after Borrower's default. Borrower also shall pay all
      court costs and such additional fees as may be directed by the court.

      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.

Loan No: 70000105                   (CONTINUED)                           PAGE 5

      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 Loan to one or more purchasers, whether related or
      unrelated to Lender. 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 Borrower 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 Loan 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 Loan irrespective of the failure or insolvency of any holder of any
      interest in the Loan. 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.

      GOVERNING LAW. THIS AGREEMENT WILL BE GOVERNED BY FEDERAL LAW APPLICABLE
      TO LENDER AND, TO THE EXTENT NOT PREEMPTED BY FEDERAL LAW, THE LAWS OF THE
      SLATE OF ARIZONA WITHOUT REGARD TO ITS CONFLICTS OF LAW PROVISIONS. THIS
      AGREEMENT HAS BEEN ACCEPTED BY LENDER IN THE STATE OF ARIZONA.

      CHOICE OF VENUE. If there is a lawsuit, Borrower agrees upon Lender's
      request to submit to the jurisdiction of the courts of MARICOPA County,
      State of Arizona.

      NO WAIVER BY LENDER. 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 of Borrower's or any Grantor's obligations 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 to subsequent instances where such
      consent is required and in all cases such consent may be granted or
      withheld in the sole discretion of Lender.

      NOTICES. Any notice required to be given under this Agreement shall be
      given in writing, and shall be effective when actually delivered, when
      actually received by telefacsimile (unless otherwise required by law),
      when deposited with a nationally recognized overnight courier, or, if
      mailed, when deposited in the United States mail, as first class,
      certified or registered mail postage prepaid, directed to the addresses
      shown near the beginning of this Agreement. 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. For notice purposes, Borrower agrees to keep
      Lender informed at all times of Borrower's current address. Unless
      otherwise provided or required by law, if there is more than one Borrower,
      any notice given by Lender to any Borrower is deemed to be notice given to
      all Borrowers.

      SEVERABILITY. If a court of competent jurisdiction finds any provision of
      this Agreement to be illegal, invalid, or unenforceable as to any
      circumstance, that finding shall not make the offending provision illegal,
      invalid, or unenforceable as to any other circumstance. If feasible, the
      offending provision shall be considered modified so that it becomes legal,
      valid and enforceable. If the offending provision cannot be so modified,
      it shall be considered deleted from this Agreement. Unless otherwise
      required by law, the illegality, invalidity, or unenforceability of any
      provision of this Agreement shall not affect the legality, validity or
      enforceability of any other provision of this Agreement.

      SUBSIDIARIES AND AFFILIATES OF BORROWER. To the extent the context of any
      provisions of this Agreement makes it appropriate, including without
      limitation any representation, warranty or covenant, the word "Borrower"
      as used in this Agreement shall include all of Borrower's subsidiaries and
      affiliates. 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 of Borrower's subsidiaries or
      affiliates.

      SUCCESSORS AND ASSIGNS. All covenants and agreements by or on behalf of
      Borrower contained in this Agreement or any Related Documents shall bind
      Borrower's successors and assigns and shall inure to the benefit of Lender
      and its successors and assigns. Borrower shall not, however, have the
      right to assign Borrower's rights under this Agreement or any interest
      therein, without the prior written consent of Lender.

      SURVIVAL OF REPRESENTATIONS AND WARRANTIES. Borrower understands and
      agrees that in extending Loan Advances, Lender is relying on all
      representations, warranties, and covenants made by Borrower in this
      Agreement or in any certificate or other instrument delivered by Borrower
      to Lender under this Agreement or the Related Documents. Borrower further
      agrees that regardless of any investigation made by Lender, all such
      representations, warranties and covenants will survive the extension of
      Loan Advances and delivery to Lender of the Related Documents, shall be
      continuing in nature, shall be deemed made and redated by Borrower at the
      time each Loan Advance is made, and shall remain in full force and effect
      until such time as Borrower's Indebtedness shall be paid in full, or until
      this Agreement shall be terminated in the manner provided above, whichever
      is the last to occur.

      TIME IS OF THE ESSENCE. Time is of the essence in the performance of this
      Agreement.

      WAIVE JURY. ALL PARTIES TO THIS AGREEMENT HEREBY WAIVE THE RIGHT TO ANY
      JURY TRIAL IN ANY ACTION, PROCEEDING, OR COUNTERCLAIM BROUGHT BY ANY PARTY
