                            PURCHASER'S DUE DILIGENCE

        6.1 SELLER'S DELIVERIES: PURCHASER'S INDEPENDENT REVIEW. Within three
(3) days following the Escrow Agent's receipt of the initial $25,000.00 Earnest
Money Deposit, Seller shall deliver to Purchaser: (i) a complete list of all
individuals who are employed by Seller and exclusively assigned to perform
services in connection with Seller's operation of the Property; (ii) a true and

limitations and conditions hereinafter expressly set forth herein, upon the
Escrow Agent's receipt of the initial $25,000 Earnest Money Deposit and
continuing thereafter until the Closing or termination of this Agreement,
whichever occurs first, Seller shall provide Purchaser and its agents or
consultants with access to the Property to inspect each and every part thereof
to determine its present condition and to conduct such physical and
environmental studies (including, but not limited to environmental, asbestos,
structural and mechanical studies) as it deems appropriate, and access to all
records and correspondence relating to the ownership and management of the
Property and the operation of the Property. All of the inspections,
investigations, review of documents and other activities of Purchaser conducted
pursuant to this Section 6.1 shall be conducted at the expense of Purchaser
without contribution from Seller of any kind or amount. Seller shall reasonably
cooperate with Purchaser in dealing with Purchaser's agents, representatives and
inspectors and in arranging prompt and complete access to the Property. In
connection with any entry by Purchaser, or its agents, employees or contractors
onto the Property, Purchaser shall give Seller reasonable advance notice of such
entry, and shall endeavor to undertake and conduct all such inspections or tests
in a manner that is calculated to cause as little disruption to the normal
operations of the Property and its tenants as is reasonably possible. Purchaser
shall indemnify Seller against and defend and hold Seller harmless from and
against any and all claims, demands or causes of action and any and all
liability, loss, damages costs or expense (including, without limitation, court
costs, expert witness fees and reasonable attorney's fees) to the extent the
same arise out of, relate to or are in any way connected with any entry on the
Property by Purchaser, its agents, employees or contractors in the course of
performing the inspections, testings or inquiries provided for in this Agreement
or the performance of any such inspection, test or inquiry, provided that there
shall be no indemnification for any conditions identified as a result of any
such inspection, test or inquiry. Further, Purchaser shall repair any material
damage which may be caused to the Property or any improvements located thereon
as a result of such entry, inspection, testing or inquiries, which obligation
shall include, without limitation, replacement of any improvements that cannot
be repaired and otherwise restoring the Property to its original condition,
ordinary wear and tear excepted.
<PAGE>

        6.2 PURCHASER'S RIGHT TO TERMINATE PRIOR TO DUE DILIGENCE EXPIRATION
DATE. Purchaser shall have until the Due Diligence Expiration Date in which to
conduct its due diligence investigations and analysis of the Property and of all
information pertaining to the Property to determine whether the Property is
acceptable to Purchaser, in Purchaser's sole and absolute discretion. If, during
the Due Diligence Period, Purchaser becomes aware of any condition with respect
to the Property that Purchaser determines makes the Property unsuitable for
Purchaser's intended use of the Property or makes it impracticable for the
Purchaser to obtain financing with respect thereto or otherwise makes the
Property undesirable to Purchaser, in Purchaser's sole and absolute discretion,
Purchaser may, as its sole and exclusive right and remedy, terminate this
Agreement by giving written notice of termination to Seller on or before the Due
Diligence Expiration Date. If Purchaser does not give such notice of termination
on or before the Due Diligence Expiration Date, Purchaser shall be deemed to
have waived its right to terminate this Agreement pursuant to this Section 6.2
and this Agreement shall continue in full force and effect. In the event of such
termination, the Earnest Money shall be immediately returned to Purchaser and
thereafter, this Agreement shall terminate.

        6.3 TITLE COMMITMENT AND SURVEY. Seller shall obtain and deliver to
Purchaser for Purchaser's review, within thirty (30) days of this Agreement, a
current commitment for an ALTA owner's policy of title insurance (the "Title
Commitment") on the Real Property issued by the Title Company, showing legal
title to be vested in Seller in conformity with subsection 8.1(e) below, along
with copies of the underlying title documents. Upon execution of this Agreement,
Seller will also deliver to Purchaser the most recent survey of the Property in
Seller's possession and as soon as is reasonably possible thereafter, and in all
events within thirty (30) days following the date of this Agreement, Purchaser
may obtain, at its sole cost and expense, a current ALTA "as built" survey of
the Property (showing the Improvements on the Property) certified to Purchaser
and the Title Company (the "Survey"). Purchaser shall have thirty (30) days
after receipt of the Title Commitment and the Survey to examine such information
and make any objections thereto, other than conditions which are listed as
exceptions in subsection 8.1(e) below, which conditions are expressly excluded
herefrom. Said objections shall be made in writing and delivered to Seller on or
before the expiration of such thirty (30) day period. If any objections to the
Title Commitment or Survey are properly made on or before the expiration of such
thirty (30) day period, then the following shall apply: (i) if Purchaser's
objection can be cured on or before the Closing Date by the payment of funds to
release a mortgage, lien, security interest or other encumbrance on the Property
(a "Monetary Objection"), then Seller shall cure such objection at or before
time of the scheduled Closing Date; (ii) if Purchaser's objection is not a
Monetary Objection (a "Non-Monetary Objection"), then Seller shall notify
Purchaser, in writing, within fifteen (15) days after Seller's receipt of
Purchaser's written notice describing such Non-Monetary Objection if Seller will
attempt to cure such Non-Monetary Objection on or before the scheduled Closing
Date. If the Seller notifies the Purchaser that it intends to attempt to cure
such Non-Monetary Objection, then the Seller shall immediately undertake and
diligently pursue a cure for such Non-Monetary Objections on or before the
Closing Date. If the Seller notifies the Purchaser that the Seller will not
attempt to effect a cure for such Non-Monetary Objection or if the Seller shall
fail to effect a cure for such Non-Monetary Objection on or before the Closing

<PAGE>

Date, then in either event, the Purchaser's sole and exclusive rights and
remedies with respect to such failure shall be to: (i) waive said objection in
writing and proceed with Closing; or (ii) to terminate this Agreement, in which
event the Earnest Money shall be immediately returned to Purchaser and
thereafter this Agreement shall terminate. At Closing, and as a condition
thereto, the Title Commitment shall be updated by the Title Company to the
Closing Date thereby obligating the Title Company to issue to Purchaser a title
policy consistent with the provisions of the Title Commitment (modified to
reflect any objection which may have been cured in accordance with this Section
6.3) and the title policy shall contain such title endorsements as Purchaser
shall reasonably request.

        7.5 PURCHASER'S FIRST RIGHT OF REFUSAL TO RENT VACANT SPACE. In the

legal or accounting fees or expenses incurred by Seller insofar as the same

of commercially reasonable efforts, is unable to assume Seller's Loan and first
mortgage, Purchaser shall immediately notify Seller of such fact, in writing,

damages, including without limitation, direct, punitive, speculative or
consequential damages; or (ii) pursue all remedies available to it hereunder or
otherwise, at law or in equity, including without limitation the right to seek
specific performance of Purchaser's obligations hereunder. In the event Seller
elects to terminate this Agreement and retain the Earnest Money as liquidated
damages, the Earnest Money shall be immediately paid to Seller by the Title
Company, and Purchaser agrees to take all such actions and execute and deliver
all such documents necessary or appropriate to effect such payment.

        12.2 SELLER DEFAULTS. In the event that Seller, on or prior to the
Closing Date, shall default in the performance of its obligations hereunder, and
provided Purchaser is not itself then in default hereunder, Purchaser may,
except as is otherwise expressly limited herein, pursue all remedies available
to it hereunder or otherwise at law or in equity, including without limitation,
the right to seek specific performance of Seller's obligations hereunder.

        12.3   INDEMNIFICATION.
               (a) Seller (referred to in such capacity as the "Indemnitor")
hereby agrees to indemnify and hold Purchaser (referred to in such capacity as
the "Indemnitee") harmless from and against any and all Liabilities, as
hereinafter defined, to third parties which arise out of, are proximately caused
by: (i) the ownership or operation of the Property by Seller at any time prior
to the Closing, (ii) any liabilities or obligations arising under any of the
Leases, the Seller's Contracts, the licenses or permits to the extent the same
first arise and relate to periods of time occurring before the Closing Date;
(iii) the failure of Seller to pay or preform any liability or obligation
retained by Seller promptly as the same become due; or (iv) any breach by Seller
of any representation, warranty, covenant, agreement or obligation of Seller in
this Agreement or in any other agreement, certificate, undertaking or document
executed, issued or delivered to Purchaser by Seller in connection herewith.

               (b) Purchaser (referred to in such capacity as the "Indemnitor"),
hereby agrees to indemnify and hold Seller (referred to in such capacity as the
"Indemnitee") harmless from and against any and all Liabilities, as hereinafter
defined, to third parties which arise out of or are proximately caused by: (i)
the ownership or operation of the Property by Purchaser after the Closing Date;
(ii) any liability or obligation arising under the Leases or the Seller's
Contracts to the extent the same first arise and relate to events or periods of
time which occur after the Closing Date; (iii) the failure of Purchaser to pay
or perform any of the Assumed Liabilities promptly as the same become due; or
(iv) any breach by Purchaser of any representation, warranty, covenant,
agreement or obligation of Purchaser in this Agreement or in any related
agreement, certificate, undertaking or document executed, issued or delivered to
Seller by Purchaser in connection herewith.

               (c) As used in this Section 12.3, "Liabilities" shall include all
damages, deficiencies, obligations, assessments, judgments, fines, penalties,
costs, expenses (including response costs, remediation expense, consultant fees,
reasonable attorneys' fees, expert witness fees or court costs) and all other
losses or expenses arising out of or in any way connected with any claim,
action, suit, proceeding, investigation or inquiry against the Indemnitee, or
with respect to the Property, whether or not successfully prosecuted.

               (d) Any Indemnitee shall give notice to the Indemnitor within 30
days of the assertion or institution of any claim, action, suit or proceeding if
the Indemnitee intends to seek indemnification hereunder. Indemnitor shall
thereafter have the right to participate, at its sole cost and expense, in the

<PAGE>

defense, settlement or other resolution thereof, including the right to retain
counsel at its own expense to defend, or cooperate in the defense of, any such
matter, and the right to consent to any settlement or compromise thereof,
provided that such consent shall not be unreasonably withheld. Notwithstanding
the foregoing, in the event that Indemnitee determines that there is a
reasonable probability that an indemnified claim or proceeding may materially
and adversely affect it, other than as a result of money payments required to be
reimbursed by Indemnitor pursuant to this Section 12.3, Indemnitee shall have
the right to prosecute the defense, and compromise or settlement of such claim
or proceeding. In any event, Indemnitor, Indemnitee, and their respective
counsel shall cooperate in the defense against, and settlement and compromise
of, any such indemnified claim or proceeding. Indemnitor shall pay to Indemnitee
any amount owing under this Section 12.3 within thirty (30) days after (i) the
completion of any investigation or inquiry, the settlement or compromise of any
claim, or suit or (ii) the entry of a final nonappealable order by a court or
other body having jurisdiction over the matter.

        12.4 REFUND OF EARNEST MONEY. In the event Purchaser is entitled to a
refund of the Earnest Money pursuant to the express terms of this Agreement, the
Earnest Money shall be immediately paid to Purchaser by the Title Company, and
Seller agrees to promptly take all such actions and execute and deliver all such
documents as may be necessary or appropriate in the reasonable opinion of the
Purchaser or the Escrow Agent to effect such payment.

        12.5 ATTORNEYS' FEES AND COSTS. In the event legal action is instituted
to interpret or enforce the provisions of this Agreement, the prevailing party
shall, to the extent permitted by law, be entitled to recover from the other
party the prevailing party's reasonable costs and reasonable attorney's fees,
including, without limitation, all reasonable costs and fees that are incurred
in any trial, on any appeal and/or in any bankruptcy proceeding.


                                   SECTION 13

                                   SECTION 14

                                  MISCELLANEOUS

        14.1 ASSIGNMENT. Purchaser may assign this Agreement, prior to the
Closing, to a corporation, limited liability company, limited partnership or
other entity, seventy-five percent (75%) or more of which is owned by Purchaser
provided, however, that such assignment shall not constitute a novation or
otherwise release Purchaser from its obligations to Seller hereunder, and in
such event, Purchaser shall nevertheless be and remain liable for the full and
faithful payment and performance of each liability and obligation required to be
paid, observed or performed by Purchaser hereunder. Except as provided in the
foregoing sentence and in Section 7.17 above, neither this Agreement nor any of
the rights or obligations hereunder may be assigned by Purchaser or Seller
without the prior written consent of the other party.

        14.2 NO THIRD PARTY BENEFICIARIES. This Agreement shall be for the sole
benefit of the parties hereto, their permitted assignees, and their respective
heirs, successors, permitted assigns, and legal representatives and is not
intended, nor shall it be construed, to give any person, other than the parties
hereto, their permitted assignees, and their respective heirs, successors,
permitted assigns and legal representatives, any legal or equitable right,
remedy or claim hereunder.

        14.3 CHOICE OF LAW. This Agreement shall be governed by, and construed
in accordance with, the internal laws of the State of Nebraska. Any legal action
or proceeding with respect to this Agreement or any document related hereto
shall be brought only in the district courts of Nebraska, or the United States
District Court for the District of Nebraska, and in connection with any suit
initiated by Purchaser, the parties, by execution and delivery of this
Agreement, hereby accept for themselves with respect to their property,
generally and unconditionally, the jurisdiction of the aforesaid courts and do
hereby irrevocably waive any objection, including, without limitation, any FORUM
NON CONVENIENS, which any of them may now or hereafter have to the bringing of
such action or proceeding in such jurisdictions.

<PAGE>

        14.4 INCORPORATION BY REFERENCE. Each of the recitals set forth at the
beginning of this Agreement, and each exhibit, schedule or document which is
referred to herein and which is attached hereto shall be deemed to be
incorporated herein and made a part hereof by such reference to the same extent
and with the same effect as if the same were set forth herein in their entirety.

        14.5 ENTIRE AGREEMENT; AMENDMENTS. This Agreement, together with all
exhibits and schedules hereto, constitutes the entire agreement among the
parties pertaining to the subject matter hereof and supersedes and replaces all
prior contracts, agreements, understandings, negotiations and discussions,
whether oral or written, of the parties in regard thereto.
        14.6 Modification or Amendment. No supplement, modification or amendment
of this Agreement shall be binding unless the same is reduced to writing and is
signed by all of the parties hereto.

        14.7 WAIVER. No waiver of any of the provisions of this Agreement or any
breach of any provision of this Agreement shall be deemed or shall constitute a
waiver of any other provision or breach hereof (whether or not similar), nor
shall such waiver constitute a continuing waiver unless otherwise expressly
provided in writing.

        14.8 INVALIDITY. It is the intention of the parties that this Agreement
and each provision hereof shall constitute a binding and legally enforceable
agreement. If any provision of this Agreement, or any covenant, obligation or
agreement contained herein is determined by a court of competent jurisdiction to
be invalid or unenforceable, then, unless such determination shall have the
effect of depriving either Purchaser or Seller of any material benefit of its
bargain, such determination shall not affect any other provision, covenant,
obligation or agreement, each of which shall be construed and enforced as if
such invalid or unenforceable portion were not contained therein and each such
valid and enforceable provision, covenant, obligation or agreement shall be
deemed to be effective, operative, made, entered into or taken in the manner and
to the full extent permitted by law.

        14.9 INTERPRETATIONS. Any uncertainty or ambiguity existing herein shall
not be interpreted against either party because such party prepared any portion
of this Agreement, but shall be interpreted according to the application of
rules of interpretation of contracts generally. The headings and table of
contents (if any) used in this Agreement are inserted for convenience and
reference only and are not intended to be an integral part of or to affect the
meaning or interpretation of this Agreement.

        14.10 TIME IS OF THE ESSENCE, COMPUTATION OF TIME. Time is of the
essence with respect to every covenant, condition to be satisfied, and action to
be taken hereunder, and the parties shall proceed accordingly with respect to
every action necessary, proper or advisable to make effective the transactions
contemplated by this Agreement. Whenever the last day for the exercise of any
privilege or the discharge of any duty hereunder shall fall upon any day which
is not a business day, the party having such privilege or duty may exercise such
privilege or discharge such duty on the next succeeding business day.
<PAGE>

        14.11 EXCULPATION OF RELATED PARTIES. Anything herein to the contrary
notwithstanding or in any of the documents executed pursuant to this Agreement
(the Agreement and said documents being hereinafter collectively referred to as
the "Sale Documents"), or provided under or required by law, the Sale Documents
shall not bind or impose any liability on any officers, directors, shareholders,
partners, members, managers, advisors, employees or other agents or affiliates
of Seller or Purchaser, but shall only be binding on Seller and Purchaser and
their respective assets.

        14.12 SURVIVAL. Except as is otherwise expressly provided herein, all
terms, covenants, conditions and agreements set forth in this Agreement,
including, without limitation, the indemnity provisions set forth in Section
12.3 which by their terms contemplate or require performance which is to extend
beyond or occur after the Termination or Closing of this Agreement shall survive
termination of this Agreement and shall be and remain in full force and effect
and be enforceable as between the parties hereto in accordance with their terms.

        IN WITNESS WHEREOF, the parties hereto have caused this Agreement to be
executed and delivered as of the day and year first above written.
