which Lessee now has or may have, to hold or retain any such property under any
exemption laws now or hereafter in force in the State of New Mexico, or in any
other way. It is the intent of the parties hereto to hereby recognize in Lessor,
Lessor's heirs, personal representatives, assigns or successors in interest, a
valid first lien as provided by the laws of New Mexico, upon any and all goods,
chattels, and other property belonging to Lessee and located in said premises,
as security for the payment of said rent and fulfillment of the faithful
performance of the agreements, covenants, terms, and conditions hereof as herein
provided, anything hereinbefore mentioned to the contrary notwithstanding. And
if at any time said term shall be ended at such election of Lessor, Lessor's
heirs, personal representatives, assigns, or successors in interest, as
aforesaid, or in any other way, Lessee, Lessee' heirs, personal representatives,
assigns, or successors in interest, do hereby covenant and agree to surrender
and deliver up the above-described premises and property peaceably to Lessor,
Lessor's heirs, personal representatives, assigns, or successors in interest,
immediately upon the termination of said term as aforesaid, and if Lessee shall
remain in possession of the same ten (10) days after ,notice of such default, or
after the termination of the Lease in any or the ways above named, Lessee shall
be deemed guilty of a forcible detained of said premises under the laws of New
Mexico and shall be subject to all the conditions and provisions above named,
and shall also be subject to eviction and removal forcible or otherwise, with or
without process of law as above stated. Further, it is covenanted and agreed by
and between the parties hereto that at any time after any such termination, the
Lessor may relet the demised premises, or any part thereof, in the name of the
Lessor or otherwise, for such term and on such conditions as the Lessor, in
Lessor's sole and absolute discretion, may determine, and may collect and
receive the rent therefor. Moreover, in the event Lessor relets the demised
premises, or any part thereof, it is explicitly understood and agreed by and
between the parties hereto that the term may be greater or lesser than the
period which would otherwise have constituted the balance of the term of this
Lease, and the conditions may include free rent of other concessions which may
be reasonably required to induce another party to lease the demised premises.
Notwithstanding anything herein to the contrary, the Lessor shall have no
obligation hereunder to relet the demised premises, or any part thereof, and
shall in no way be responsible or liable for any failure to collect any rent due
upon such reletting. It is also covenanted and agreed by and between the parties
hereto that no such termination of this Lease shall relieve the Lessee of its
liabilities and obligations under this Lease, and such liabilities and
obligations shall survive any such termination. In the event of any such
termination, whether or not the demised premises, or any part thereof, shall
have been relet, the total remaining balance of the rent which would be due and
payable for the remainder of there term of this Lease, if this Lease were still
in effect, less the net proceeds of any reletting effected pursuant to the
Lessor's sole discretion, after deducting from the net proceeds all of the
Lessor's expenses in connection with such reletting, including, without
limitation, all repossessions costs, brokerage commissions, legal expenses,
reasonable attorney's fees, alteration costs, and expenses of preparation for
such reletting, shall become immediately due and payable, as for liquidated
damages of the Lessee's default. Nothing herein contained, however, shall limit
or prejudice the right of Lessor to prove for and obtain as liquidated damages
by reason of such termination, an amount equal to the maximum allowed by any
statute or rule of law in effect at the time when, and governing the proceedings
in which, such damages are to be proved, whether or not such amount be greater
than, equal to, or less than the amount of the difference referred to above, and
whether or not such amount shall be immediately or otherwise due and payable.
Further, it is covenanted and agreed to by and between the parties hereto, that
in addition to other remedies provided for in this Lease, the Lessor shall be
entitled to restraint by injunction of the violation, or attempted or threatened
violation, of any agreement or covenant of this Lease, or to a decree
specifically compelling performance of any such agreement or covenant. The
Lessee, the Lessee's heirs, personal representatives, assigns and successors in
interest, hereby expressly waives, so far as permitted by law, the service of
any notice of intention to re-enter provided for in any statute, or of the
institution of legal proceedings to that end. Lessee, the Lessee's heirs,
personal representatives, assigns, and successors in interest, also

                                     Page 5

<PAGE>   6

hereby expressly waives any right or redemption or re-entry or repossession or
to restore the operation of this Lease case the Lessee shall be disposed by a
judgment or by a warrant of any court or judge or in case of re-entry or
repossession by the Lessor. It is further covenanted and agreed by and between
the parties hereto, that the Lessee shall pay and discharge all costs,
reasonable attorney's fees, and expenses incurred by Lessor, lessor's heirs,
personal representatives, assigns, or successors in interest, in enforcing the
covenants of this Lease, or incurred by Lessor in pursuing any or all remedies
which are or may be available hereunder or allowed at law or in equity, or
incurred by Lessor in connection with reletting the demised premises.

XIX.     LESSOR'S REMEDIES ARE CUMULATIVE.

         The specified remedies to which the Lessor may resort under the terms
of this Lease are cumulative and are not intended to be exclusive of any other
remedies or means of redress to which the Lessor may be lawfully entitled in
case of any breach or threatened breach by the Lessee of any of the agreements
and covenants herein contained.

XX.      WAIVERS.

         Lessee, for and in consideration of this Lease and the demise of the
said premises, agrees and covenants with Lessor that the delay or omission in
the enforcement of any of the agreements and covenants herein contained, or in
the exercise of any Lessor's rights hereunder, shall not affect the duty of the
Lessee to thereafter faithfully fulfill and perform all of the agreements and
covenants herein contained, and that the failure, neglect, or omission of Lessor
to terminate this Lease for any one or more breaches of any agreements and
covenants hereof, shall not be deemed a consent by Lessor of such breach and
shall not impede, impair, stop, bar, or prevent Lessor from thereafter
terminating this Lease, either for such violation, or for prior or subsequent
violations of any covenant or agreement hereof.

XXI.     BINDING ON HEIRS, PERSONAL REPRESENTATIVES, ASSIGNS, AND SUCCESSORS IN

expressed, and shall be construed as covenants running with the land; and
wherever reference is made to either of the parties hereto, it shall be held to
and include and apply also to the heirs, personal representatives, successors,
and assigns of such party, as if in each and every case so expressed.
