Company (or another national title insurance company acceptable to Buyer in its

title to the Property, with exceptions and exclusions to coverage for the
Permitted Encumbrances and for the standard exceptions and exclusions to

                  4.2 INSPECTIONS. From the date hereof through and including
the earlier of (i) the date on which the Closing occurs, or (ii) the date on
which this Agreement is terminated in accordance with the terms and conditions
hereof, Buyer, its agents, employees and contractors, shall be entitled to
perform, at Buyer's sole cost and expense, such inspections of the Property and
all matters relating thereto and each aspect thereof that Buyer determines
necessary or appropriate. Such inspections may include, without limitation,
reviewing and assessing the Commitment and other title matters concerning the
Property, conducting surveys, reviewing and assessing the compliance of the
Property with applicable laws, rules and regulations such as those relating to
zoning, land-use matters, building, fire and safety codes, and reviewing and
analyzing environmental conditions affecting the Property. In connection
therewith, Buyer and it's agents may enter upon the Property (as coordinated
through Seller's property manager), including all leased areas (subject to the
rights of tenants), upon reasonable prior notice to Seller, to perform
inspections and tests of the Property and matters related thereto, including
test borings, environmental studies, examinations and tests of structural and
mechanical systems within the Improvements, and examining the books and records
of Seller and Seller's property manager relating to the Property. If Buyer
wishes to engage in any testing which could damage or disturb any portion of the
Property, Buyer shall obtain Seller's prior consent thereto. Without



                                      -4-
<PAGE>

limiting the generality of the foregoing, Seller's written approval shall be
required prior to any testing or sampling of surface or subsurface soils,
surface water, groundwater, or any materials in or about the Improvements.

                           4.2.1 INSURANCE. Contemporaneously with the execution
hereof, Buyer shall deliver to Seller evidence reasonably satisfactory to Seller
that Buyer and all of Buyer's agents and contractors entering onto the Property
have obtained comprehensive general liability insurance naming Seller as an
additional insured with respect to the Property in an amount of not less than
$2,000,000.00 and written on such forms as are reasonably acceptable to Seller.

                           4.2.2 LIMITATION ON INSPECTIONS. In connection with
the right to enter upon the Property set forth in this Article 4, Buyer agrees
(i) not to interfere materially with the operation of the Property or any
tenants of the Property, (ii) to restore the Property to its prior condition
after the performance of any such inspections, and (iii) to hold harmless and
indemnify Seller and Seller's agents, employees, contractors, and tenants from
any and all damages, claims, losses and liabilities (including, without
limitation, reasonable legal fees and expenses) arising from or related to
Buyer's or Buyer's agents' or contractors' or employees' actions or omissions or
its failure to satisfy the conditions of subsections (i) and (ii) above. The
provisions of this subparagraph shall survive the Closing and delivery of the
Deed (as hereinafter defined) or termination of this Agreement.

                  4.3 TERMINATION OPTION. The period of time between the date
hereof and 4:00 p.m. on September 17, 2000 is hereinafter referred to as the
"Inspection Period." Buyer, in its sole discretion, may elect to terminate this
Agreement, for any reason or no reason, by giving notice of such election to
Seller on any day prior to and including the final day of the Inspection Period
(time being of the essence of the giving of such notice), in which event, except
as expressly set forth herein, neither Seller nor Buyer shall have any further
liability or obligation to the other hereunder. If such termination by Buyer
occurs on or prior to the date which is twenty (20) days after the date of this
Agreement, then the Initial Deposit shall be returned to Buyer; however, if such
termination occurs after said twenty (20) day period, then the Initial Deposit
shall be nonrefundable and shall be retained by Seller as it's own property,
free and clear of any rights or claims of Buyer. If Buyer does not elect to
terminate this Agreement, then by not later than the expiration of the
Inspection Period, Buyer shall deliver the Additional Deposit to Escrow Agent.
If Buyer timely delivers the Additional Deposit to Escrow Agent, as aforesaid,
the delivery of the Additional Deposit shall be considered an election by Buyer
not to terminate this Agreement, and all of the conditions of this Section 4.3
shall be considered satisfied and the Buyer's termination option under this
Section 4.3 shall be null and void and of no further force or effect, and this
Agreement and the obligations of the parties shall remain in full force and
effect. Without limiting the foregoing, if Buyer fails to deliver the Additional
Deposit by not later than the expiration of the Inspection Period, then such
failure shall be considered to be an election by Buyer to terminate this
Agreement, in which event the Initial Deposit shall be nonrefundable and shall
be retained by Seller as its own property, free and clear of any rights or
claims of Buyer, and except as expressly set forth herein, neither Seller nor
Buyer shall have any further liability or obligation to the other hereunder.
Except as set forth in this Article 4, there



                                      -5-

more than $100,000 to remove such title defects and/or satisfy such conditions.
In the event Seller shall be unable to convey title or satisfy the conditions to
Closing on the date of Closing in accordance with this Agreement, then Buyer
shall have the option, exercisable by notice to Seller at or prior to the
Closing Date, as the same may have been extended, of either: (i) accepting at
Closing such title as Seller is able to convey and/or waiving any defect, and
waiving any other condition to Closing as herein required, with no deduction
from or adjustment of the Purchase Price; or (ii) terminating this Agreement, in
which event all obligations, liabilities and rights of the parties under this
Agreement shall terminate except as otherwise herein provided, and the entire
Deposit shall be returned to Buyer.

         7. APPORTIONMENTS; TAXES; EXPENSES.

                  7.1      APPORTIONMENTS.

                           7.1.1 TAXES. Applicable real estate and personal
property taxes for the Property shall be apportioned as of the Closing with the
Seller being responsible for all taxes payable with respect to the period up to
the Closing Date and with Buyer being responsible for such taxes payable with
respect to the period from and after the Closing Date and, if necessary, the net
amounts shall be added to or deducted from, as the case may be, the Purchase
Price. The term "real estate taxes" shall include any installments of
betterment, special or similar assessments. If the amount of such taxes is not
known at the Closing, such taxes shall be apportioned on the basis of the taxes
assessed for the preceding tax period, with a reapportionment within sixty (60)
days of the Closing (or as soon thereafter as such taxes are determined) and if
the taxes which are to be apportioned shall thereafter be reduced by abatement,
the amount of such abatement, less the reasonable cost of obtaining the same,
shall be apportioned between the parties. Neither party shall be obligated to
commence or prosecute abatement proceedings.

                           7.1.2 OPERATING EXPENSES. All maintenance,
management, electricity, water, gas, sewage and other utility and operating
expenses applicable to the Property and payments under any Contracts shall be
prorated between the Seller and Buyer as of the Closing based on estimates of
the amounts that will be due and payable on the next payment date, unless final
readings or invoices therefor as of the Closing shall have been obtained, in
which case such final readings or invoices shall be utilized as the basis for
adjustment. During the sixty (60) day period following the Closing, Seller and
Buyer shall recalculate the foregoing adjustment with the result that Seller
shall pay for those expenses attributable to the period of time prior to the
Closing Date and Buyer shall pay for those expenses attributable to the period
of time commencing with the Closing Date. Any and all deposits held by utility
companies or with other providers of services to the Property shall remain the
property of Seller and be returned to the Seller by such companies and
providers, except to the extent that Buyer elects to credit to Seller the amount
of any such deposits.

                  7.2      EXPENSES.

                           7.2.1 SELLER'S EXPENSES. Seller shall pay (a) the
recordation taxes incident to the recording of the Deed, and (b) expenses
incurred by Seller in connection with the transaction contemplated by this
Agreement.

                           7.2.2 BUYER'S EXPENSES. Buyer shall pay expenses
incurred by Buyer in connection with the transaction contemplated by this
Agreement.

                           7.2.3 OTHER EXPENSES. Except as herein specifically
provided, Seller and Buyer shall allocate all closing costs between them in
accordance with standard practice in Provo, Utah.

                  7.3 ERRORS; SURVIVAL. During the sixty (60) day period
following the Closing, Buyer and Seller agree to re-prorate the closing
adjustments in order to correct any error in performing the prorations or to
reflect information that becomes available during such 60-day period indicating
that the prorations performed at Closing were not accurate. The provisions of
this Article 7 shall survive the Closing.

         8. EMINENT DOMAIN; CASUALTY.

                  8.1 If all or substantially all of the Property is taken by
eminent domain after the date hereof and prior to the Closing, this Agreement
shall terminate and the Deposit shall be returned to Buyer. If a taking by
eminent domain of a material part of the Property shall be made after the date
hereof and prior to the Closing, then the Seller shall promptly notify Buyer of
the same (the "Taking Notice"), and Buyer shall have the right to terminate this
Agreement by notice from Buyer to Seller given on or before the date that is the
earlier to occur of: (a) after ten (10) days the date of the Taking Notice, and
(b) the Closing. In the event Buyer does not terminate this Agreement, Buyer
shall accept such title to the Property as the Seller can deliver subject to
such taking, in which case Seller shall pay over or assign to Buyer all rights
and proceeds arising by reason of such taking (less any collection costs
incurred by Seller in connection therewith and any costs and expenses incurred
by Seller to restore the Property) and Buyer shall pay the Purchase Price
without reduction.

         If a taking by eminent domain of an immaterial part of the Property
shall be made after the date hereof and prior to the Closing, then the Buyer
shall accept such title to the Property as the Seller can deliver subject to
such taking, in which case Seller shall pay over or assign to Buyer all rights
and proceeds arising by reason of such taking (less any collection costs
incurred by Seller in connection therewith and any costs and expenses incurred
by Seller to restore the Property) and Buyer shall pay the Purchase Price
without reduction. For purposes of this Section 7.1, "material" shall mean any
loss due to a condemnation which (a) materially impairs the current use of the
Property, (b) eliminates more than ten percent (10%) of the parking spaces
servicing the Property, (c) materially and adversely affects access to the
Property or (d) results in



                                      -11-
<PAGE>

tenants leasing an aggregate of more than ten (10%) of the then leased area of
the Property having the right to terminate their Leases.

                  8.2 If any time after the date hereof and prior to the Closing
any portion of the Improvements is destroyed or damaged as a result of fire or
any casualty, the Seller shall promptly give notice thereof to Buyer. The rights
and obligations of the parties by reason of such destruction or damage shall be
as follows:

                           8.2.1 If the "Cost of Repair and Restoration" (as
hereinafter defined) of such destruction or damage shall be $500,000 or less,
the obligations of the parties hereunder shall not be affected by such
destruction or damage, and Buyer shall accept title to the Property in its
destroyed or damaged condition. Buyer shall pay the Purchase Price without
reduction, and the Seller shall pay over or assign to Buyer without recourse all
rights to any proceeds of insurance payable with respect to such destruction or
damage (less any collection costs incurred by Seller in connection therewith and
any costs and expenses incurred by Seller to restore the Property) and Buyer
shall receive a credit against the Purchase Price in the amount of any
deductible.

                           8.2.2 If the Cost of Repair and Restoration of such
destruction or damage shall exceed $500,000, Buyer shall have the right to
terminate this Agreement by notice from Buyer to Seller given on or before the
date that is the earlier to occur of (a) ten (10) days after the date of the
Cost Notice (as hereinafter defined) and (b) the Closing Date. In the event
Buyer does not terminate this Agreement, Buyer shall accept title to the
Property in its destroyed or damaged condition in accordance with and subject to
the provisions of subparagraph 8.2.1 above. If Buyer so terminates this
Agreement, then the Deposit shall be paid to Buyer.

                           8.2.3 The term "Cost of Repair and Restoration" shall
mean the amount of Seller's good faith estimate of the actual cost of repair and
restoration to restore the Property to the condition it was in immediately prior
to the casualty. Seller shall send Buyer notice of the Cost of Repair and
Restoration (the "Cost Notice") promptly after making the aforesaid estimate.

                  8.3 The provisions of Section 8.2 shall survive the delivery
of the Deed and the Closing.

         9. REMEDIES.

                  9.1 SELLER'S REMEDIES. If Seller shall have fulfilled all of
its obligations under this Agreement in the time and manner specified herein and
Buyer breaches any of its obligations hereunder, then Seller shall, as its sole
remedy therefor, be entitled to receive the entire Deposit, as liquidated
damages (and not as a penalty) in lieu of, and as full compensation for, all
other rights or claims of Seller against Buyer by reason of such default.
Thereupon this Agreement shall terminate and the parties shall be relieved of
all further obligations and liabilities hereunder, except as expressly set forth
herein. Buyer and Seller acknowledge that the damages to Seller resulting from
Buyer's breach would be difficult, if



                                      -12-
<PAGE>

not impossible, to ascertain with any accuracy, and that the liquidated damage
amount set forth in this Section represents both parties' efforts to approximate
such potential damages.

                  9.2 BUYER'S REMEDIES. If Buyer shall have fulfilled all of its
obligations under this Agreement in the time and manner specified herein and
Seller breaches any of its obligations hereunder, Buyer shall have, as its sole
remedy therefor, the right either to (a) bring an action for specific
performance for conveyance of the Property on the terms set forth in this
Agreement, or (b) receive the entire Deposit, in which event this Agreement
shall terminate and the parties shall be relieved of all further obligations and
liabilities hereunder, except as expressly set forth herein.

                  9.3 REMEDIES EXCLUSIVE. By the express agreement of Buyer and
Seller, the remedies set forth in this Article 9 constitute the sole remedies at
law or in equity available to Buyer and Seller, as the case may be, on account
of the other party's breach of its obligations under this Agreement; provided,
however, to the extent any terms or provisions hereof are specifically intended
to survive the Closing and delivery of the Deed or the termination of this
Agreement, the other party shall have all remedies with respect thereto as may
be available at law or in equity. In no event, however, shall either party
hereto be liable for any consequential, special, indirect or punitive damages,
and in no event shall damages for which Seller is responsible hereunder exceed
the Purchase Price to the extent actually received by Seller at Closing.

         10. FURTHER ASSURANCES. After the Closing, Seller and Buyer agree to
perform such other acts, and to execute, acknowledge and deliver, such other
instruments, documents and other materials as the other may reasonably request
(at no cost to such party) and as shall be necessary in order to effect the
consummation of the transactions contemplated hereby. The provisions of this
Article 10 shall survive the Closing.

         11. REPRESENTATIONS OF BUYER. Buyer hereby makes the following
representations and warranties to the best of Buyer's actual knowledge as of the
date hereof and again as of the Closing, the truth and accuracy of which shall
constitute a condition to Closing for the benefit of Seller. These
representations and warranties are made as a material inducement to Seller to
enter into this Agreement, and Seller would not have entered into this Agreement
except in reliance upon the representations and warranties of Buyer made herein.
Seller shall be entitled to rely upon the representations and warranties of
Buyer.

                  11.1 AUTHORITY. Buyer is a limited liability company, duly
organized, validly existing and in good standing under the laws of the State of
Utah and Buyer has all requisite power and authority to enter into this
Agreement and all documents now or hereafter to be executed and delivered by
Buyer pursuant to this Agreement (collectively, "Buyer's Documents") and to
perform its obligations hereunder and under Buyer's Documents.

                  11.2 NO CONFLICT. The execution and delivery of this Agreement
and the consummation of the transactions contemplated hereunder on the part of
Buyer do not and will



                                      -13-
<PAGE>

not violate any applicable law, ordinance, statute, rule, regulation, order,
decree or judgment, conflict with or result in the breach of any material terms
or provisions of, or constitute a default under, or result in the creation or
imposition of any lien, charge, or encumbrance upon any of the property or
assets of Buyer which will not be discharged or released at Closing by reason
of, the terms of any contract, mortgage, lien, lease, agreement, indenture,
instrument or judgment to which Buyer is a party.

         Buyer's representations and warranties set forth in this Agreement
shall survive the Closing for a period of twelve (12) months and any action
brought on Buyer's representations and warranties shall be commenced within said
twelve (12) month period or shall be forever barred and waived.

         12. NOTICES. All notices, approvals, consent, requests and other
communications provided for herein shall be in writing (from either a party
hereto or its counsel) and shall be sent to the address set forth below (or such
other address as a party may hereafter designate for itself by notice to the

         Each notice, approval, consent, request, or other communication shall

         13. BROKERS. Buyer and Seller each represent to the other that it has
not dealt with any broker or agent in connection with this transaction other
than Scott McDonald and Rob T. Smith (collectively, the "Brokers"). Seller shall
pay Brokers a commission in connection with this Agreement if, as and when the
Closing shall occur and not otherwise, pursuant to a separate agreement. Each of
Buyer and Seller hereby indemnifies and holds harmless the other from all
losses, costs and expenses (including reasonable attorneys' fees and expenses)
arising out of a breach of its representation or undertaking set forth in this
Article 13. The provisions of this Article 13 shall survive Closing or the
termination of this Agreement.

         14. ESCROW AGENT.

                  14.1 All Deposits paid by BUYER under this Agreement shall be
held in escrow by Escrow Agent (the "Escrow Agent") and shall be deposited by
the Escrow Agent into an interest bearing bank account at First Security Bank of
Utah, N.A. The Escrow Agent shall hold such amounts together with all interest
accrued thereon (the "Escrow Funds") in such account until such time as it
receives:

      a)      A written notice signed by the Buyer and the Seller directing it
              to release all or a portion of the Escrow Funds to the party
              specified in such notice; or

      b)      A final order, judgment or decree of a court directing the
              disposition of the Escrow Funds.

                  14.2 The Escrow Agent shall not be responsible for the
genuineness of any signature or for the genuineness or collectibility of any
check and may rely conclusively and



                                      -15-
<PAGE>

shall be protected in relying upon, and shall have no duty or obligation to
investigate, ascertain the correctness or status of, any judgment, order,
decree, certificate, notice, request, consent, statement or other instrument
delivered to it in connection with its activities hereunder. In no event shall
the Escrow Agent be liable for any act performed or omitted to be performed by
it hereunder in the absence of willful and wanton misconduct, and in no event
shall it be liable or responsible for any failure of the banking institution in
which the Escrow Funds are held to pay any amount at the Escrow Agent's
direction or for any failure of such amounts to be covered by deposit insurance.
BUYER and SELLER hereby jointly and severally indemnify and hold the Escrow
Agent harmless from any damage, cost, liability or expense (including, but not
limited to, legal fees either paid to retained attorneys or representing the
fair value of legal services rendered by the Escrow Agent) which the Escrow
Agent may incur by reason of its actions hereunder, without prejudice to any
right which the SELLER or the BUYER may have to recover from the other for any
such damage, cost, liability or expense. Without limiting the generality of the
foregoing, in no event shall the Escrow Agent be required to take any action
unless and until it has been indemnified to its satisfaction by the party
requesting such action.

                  14.3 In the event that a dispute shall arise as to the
disposition of the Deposit, the Escrow Agent shall have the right, at its
option, to either hold the same or deposit the same with a court of competent
jurisdiction pending decision of such court, and the Escrow Agent shall be
entitled to rely upon the final decision of such court no longer subject to
appeal.

                  14.4 The Escrow Agent shall be entitled to rely upon any
judgment, certification, demand or other writing delivered to it hereunder
without being required to determine the authenticity or the correctness of any
fact stated therein, the propriety or validity thereof, or the jurisdiction of a
court issuing any such judgment. The Escrow Agent may act in reliance upon (i)
any instrument or signature believed to be genuine and duly authorized, and (ii)
advice of counsel in reference to any matter or matters connected therewith.

         15.      MISCELLANEOUS.

                  15.1 ASSIGNABILITY. Buyer may not assign or transfer all or
any portion of its rights or obligations under this Agreement to any other
individual, entity or person without the prior written consent thereto by
Seller. No assignment or transfer by Buyer will release Buyer of its obligations
hereunder.

                  15.2 GOVERNING LAW; PARTIES IN INTEREST. This Agreement shall
be governed by the laws of the State of Utah and shall bind and inure to the
benefit of the parties hereto and their respective heirs, executors,
administrators, successors, and permitted assigns.

                  15.3 RECORDING; CONFIDENTIALITY. Neither this Agreement nor
any notice or memorandum hereof shall be recorded in any public record. A
violation of this prohibition shall constitute a material breach of this
Agreement. Prior to Closing, Buyer shall maintain in strict confidence all
information received by it from Seller or obtained as a result of its inspection
of



                                      -16-
<PAGE>

the Property or review of Seller's books and records, this obligation to survive
the termination of this Agreement.

                  15.4 TIME OF THE ESSENCE. Time is of the essence of this
Agreement.

                  15.5 HEADINGS. The headings preceding the text of the
paragraphs and subparagraphs hereof are inserted solely for convenience of
reference and shall not constitute a part of this Agreement, nor shall they
affect its meaning, construction or effect.

                  15.6 COUNTERPARTS. This Agreement may be executed
simultaneously in counterparts, each of which shall be deemed an original, but
all of which together shall constitute one and the same instrument.

                  15.7 EXHIBITS. All Exhibits which are referred to herein and
which are attached hereto or bound separately are expressly made and constitute
a part of this Agreement.

                  15.8 MERGER. Except as otherwise specifically provided herein,
the acceptance of the Deed by the recordation thereof shall be deemed to be a
full and complete performance and discharge of every agreement and obligation of
Seller herein contained.

                  15.9 ENTIRE AGREEMENT; AMENDMENTS. This Agreement and the
Exhibits hereto set forth all of the covenants, representations, warranties,
agreements, conditions and undertakings between the parties hereto with respect
to the subject matter hereof, and supersede all prior and contemporaneous
agreements and understandings, inducements or conditions, express or implied,
oral or written. This Agreement may be amended, modified or altered only by an
agreement in writing, duly executed by or on behalf of the party or parties
against whom enforcement of any waiver, change, modification, consent or
discharge is sought.

                  15.10 COST OF LITIGATION. In the event of any litigation to
enforce this Agreement if either party obtains final judgment on the merits,
then the prevailing party shall be entitled to recover the reasonable actual
out-of-pocket attorneys fees and disbursements which it incurs in connection
with said action.

                  15.11 LIMITATION OF LIABILITY. In no event shall any officer,
director, partner, shareholder, agent or employee of Buyer be personally liable
for any of the obligations of Buyer under this Agreement. In no event shall any
officer, director, partner, shareholder, agent or employee of Seller be
personally liable for any of the obligations of Seller under this Agreement.

                  15.12 NO AGREEMENT UNTIL EXECUTION AND DELIVERY. The delivery
by either party of unexecuted copies of this Agreement is solely for the purpose
of review by the party to whom delivered and is in no way to be construed as an
offer or an acceptance by either party or an agreement to sell or purchase the
Property, as applicable, and neither party shall be bound by the terms hereof
until a definitive agreement satisfactory to both Purchaser and Seller has been
executed and delivered by both parties.
