condition and repair, and that STI is satisfied with and has accepted the
property in such good condition and repair.


                                   ARTICLE XII
                                    INSURANCE

1.   STI DUTY TO INSURE. STI agrees to maintain in full force and effect, at its
own cost and expense, property damage insurance issued by a company satisfactory

less than:

         $1,000,000 per person;
         $1,000,000 per accident;
         $146,671.06 property damage; and
         $1,000,000 excess liability umbrella coverage.

For all property covered by this Agreement, STI shall also provide, at its own

1.   ALL LIABILITY ASSUMED BY STI. STI assumes all risk and liability for the
loss of or damage to the equipment, for the death of or injury to any person or
property of another, and for all other risks and liabilities arising from the

its agents, and employees from any and all claims, loss, or damage MDC may

delivery, return, condition, or operation of any of the property.

3.   OBLIGATIONS SURVIVE LEASE TERM. The indemnities and assumptions of risk,
liabilities, and obligations by STI arising under this Agreement during its term
shall continue in effect after the termination of this Agreement, regardless of
the reason for termination.

necessary accident reports, including those required by law and those required
by insurers of the leased property.

2.   STIPULATED LOSS VALUE. If any property becomes lost, stolen, destroyed, or
damaged beyond repair, STI shall pay MDC in cash the "Stipulated Loss Value" as
set forth in Schedule A, less any net proceeds of insurance for the property
received by MDC. Upon payment, this Agreement shall terminate with respect to
that item of property and STI shall become entitled to the property on an
"as-is, where-is" basis, without warranty, express or implied, for any matter
whatsoever.

1.   STI IN DEFAULT. MDC, at its option, may by written notice to STI declare
STI in default on the occurrence of any of the following:

     i)   failure by STI to make payments or perform any of its obligations

STI is in default, MDC shall have the following options:

     i)   terminate the Agreement and STI's rights under the Agreement;
     ii)  declare the balance of all unpaid rent and all other charges of any
kind required of STI under the Agreement to be due and payable immediately; and,
     iii) repossess the property without legal process free of all rights of
STI in and to the property. STI authorizes MDC or MDC's agent to enter on any

<PAGE>

3.   EFFECT OF FORBEARANCE. No failure on the part of MDC to exercise any remedy
or right and no delay in the exercise of any remedy or right shall operate as a
waiver. Acceptance by MDC of rent or other payments made by STI after default
shall not be deemed a waiver of MDC's rights and remedies arising from STI's
default.

4.   FORFEITURE OF STI INTEREST ON DEFAULT. Upon default, for any reason, STI
and STI's successor in interest shall have no right, title, or interest in the
leased property, its possession, or its use. MDC shall retain all rents and
other payments of any kind made by STI under this Agreement.


                                  ARTICLE XVIII
                        RETURN OF PROPERTY ON EXPIRATION

1.   STI RETURN OF PROPERTY. Upon the expiration of this Agreement with respect
to any and all of the property, STI shall return the property to MDC, together
with all accessions, free from all damage and in the same condition and
appearance as when received by STI, allowing for ordinary wear and tear. If STI
fails or refuses to return the equipment to MDC, MDC shall have the right to
take possession of the property and for that purpose to enter any premises where
the property is located without being liable in any suit, action, defense, or
other proceedings to STI.


                                   ARTICLE XIX
                                      LIENS

1.   ENCUMBRANCES OR LIENS; NOTICE. STI shall not pledge, encumber, or create a
security interest in, or permit any lien to become effective on any leased
property. If any of these events takes place, STI shall be deemed to be in
default at the option of MDC. STI shall promptly notify MDC of any liens,
charges, or other encumbrances of which STI has knowledge. STI shall promptly
pay or satisfy any obligation from which any lien or encumbrance arises, and
shall otherwise keep the property and all right, title, and interest free and
clear of all liens, charges, and encumbrances. STI shall deliver to MDC
appropriate satisfactions, waivers, or evidence of payment.


                                   ARTICLE XX
