                            STOCK PURCHASE AGREEMENT

THIS  STOCK  PURCHASE  AGREEMENT  (this  "Agreement")  is  entered  into  as  of
February 6,  1998,  among (i) Key Rocky Mountain,  Inc., a Delaware  corporation
("Buyer") and (ii) Updike  Brothers,  Inc. Employees= Stock Ownership Retirement
Plan and Trust (the "ESOP"),  David W.  Updike Trust,  Dorothy A.  Updike Trust,
Dorothy R.  Updike  Trust,  Mary E.  Updike,  Ralph O. Updike and Daniel  Updike
(collectively, the "Shareholders").

                              W I T N E S S E T H:

WHEREAS,  Buyer is a corporation  duly organized and validly  existing under the
laws of the State of Delaware, with its principal executive offices at Two Tower
Center, 20th Floor, East Brunswick, New Jersey 08816;

WHEREAS,  Updike Brothers,  Inc. (the "Company") is a corporation duly organized
and validly existing under the laws of the State of Wyoming,  with its principal
executive offices at 2895 West Main Street, Newcastle, Wyoming 82701;

WHEREAS,  the  Shareholders  own 6,166 shares (the  "Company  Shares") of common
stock,  par value $10.00 per share, of the Company (the "Common  Stock"),  which
constitutes  all of the issued and  outstanding  shares of capital  stock of the
Company; and

WHEREAS, the Shareholders desire to sell to Buyer, and Buyer desires to purchase
from the Shareholders, all of the Company Shares.

NOW, THEREFORE, in consideration of the premises and of the mutual covenants and
agreements herein contained, the parties hereto hereby agree as follows:

                                    ARTICLE 1

                                PURCHASE AND SALE

1.1 Purchase and Sale of the Company Shares.

1.1.1 Purchase and Sale.  Subject to the terms and conditions of this Agreement,
on the date hereof, the Shareholders agree to sell and convey to Buyer, free and
clear of all  Encumbrances  (as defined in Section  2.1.8.1  hereof),  and Buyer
agrees to purchase and accept from the Shareholders,  all of the Company Shares.
In  consideration  of the sale of the  Company  Shares,  Buyer  shall pay to the
Shareholders a purchase price of $10,600,000 (the "Purchase Price") in cash, and
the Cash  Adjustment  Payment  (as defined in Section  1.2  hereof),  if any, in
accordance with Section 1.2 hereof.

1.1.2 Payment of Purchase Price.  The Purchase Price payable to the Shareholders
on the date hereof  shall be in the amounts  set forth on  Schedule 1.1.2.  Such
amounts are net of (i)  $530,000  payable to the Dillard  Group as  described in
Schedule 2.1.24,   and  (ii)  the  Cash   Adjustment   Payment  payable  to  the
Shareholders pursuant to Section 1.2.

1.1.3 Purchase  Price  Holdback.  A purchase  price holdback of $1,000,000  (the
"Purchase Price  Holdback")  will be deducted from the Cash  Adjustment  Payment
payable to the Shareholders pursuant to Section 1.2. The Purchase Price Holdback
shall be held in escrow  pursuant to the escrow  agreement dated the date hereof
(the "Escrow  Agreement") in the form of Exhibit A hereto and will be applied to
pay Environmental Assessments and Cleanup Costs (as defined in Section 3.4), Tax
Adjustments  (as  defined  in   Section 3.5),   and  to  cover   indemnification
obligations under Article IV of this Agreement.

1.1.4 Interest. Immediately before any portion of the Purchase Price Holdback is
distributed from the escrow account, maintained pursuant to the Escrow Agreement
the Buyer will pay into such escrow account an amount of cash, if any, necessary
to give the Shareholders receiving such distribution an annualized return on the
amount  distributed  equal to the  greater of (i) 8% or (ii) the  Federal  Funds
interest rate on the day before of the distribution plus 2-9/16%,  computed from
the date hereof through the date of the distribution.

1.1.5 Distribution of Purchase Price Holdback.  The Purchase Price Holdback will
be distributed to the Shareholders as follows:

1.1.5.1 Initial  Distribution.  At the time of the distribution of the assets of
the ESOP  contemplated by Section 1.6.2  of this Agreement,  the participants in
the ESOP  who  beneficially  owned an  interest  in the ESOP  entitling  them to
receive ten or fewer shares of Common Stock as of the Closing Date shall receive
a  distribution  from the Escrow Funds (as defined in the Escrow  Agreement)  an
amount equal to the unpaid  portion of the Purchase  Price forming a part of the
Purchase  Price  Holdback  allocable  to such  participants,  including  accrued
interest  through the date of the distribution as contemplated by Section 1.1.4.
The  Purchase  Price  Holdback  will  thereupon be reduced by the amount of such
distribution.

1.1.5.2 Final  Distribution.  On the third  anniversary of the date hereof,  the
Shareholders  will receive  from the Escrow  Account any portion of the Purchase
Price Holdback remaining after deduction of Environmental Assessment and Cleanup
Costs,  Tax  Adjustments  and all  amounts  necessary  to cover  indemnification
obligations  under  Article IV of this Agreement,  plus accrued interest through
such date based on their  percentage  interests  in the Company as  reflected on
Schedule 1.1.2.




1.2 Cash Adjustment Payment.  Within 60 days after the date hereof,  Buyer shall
cause to be prepared and delivered to the  Shareholders a  consolidated  balance
sheet of the Company as of the date hereof (the  "Final  Balance  Sheet")  which
balance sheet will be prepared in accordance with generally accepted  accounting
principles,  consistently  applied in all respects.  Buyer and the  Shareholders
shall  jointly  review the Final  Balance  Sheet,  and endeavor in good faith to
resolve  all  disagreements  regarding  the  entries  thereon  and reach a final
determination thereof within 90 days from the date hereof. If the parties cannot
agree on the entries to be placed on the Final Balance  Sheet,  the dispute will
be  resolved  by an  independent  accounting  firm  mutually  agreed  to by  the
Shareholders  and Buyer  (such  agreement  not to be  unreasonably  withheld  or
delayed)  whose  resolution  shall be binding  on and  enforceable  against  the
parties  hereto.  Within  10 days of  reaching  such  final  determination,  the
following adjusting payments (which shall include interest at the rate of 8% per
annum accruing from the date hereof through the payment date) shall be made:

1.2.1 If the Final Net Current  Value of the  Company  (defined  below)  exceeds
$0.00,  Buyer shall pay to the  Shareholders  the amount of such difference (the
"Cash Adjustment Payment"), or

1.2.2 If the Final Net Current Value of the Company (defined below) is less than
$0.00, Shareholders shall pay to Buyer the amount of such difference.

1.2.3 In addition,  any capital  expenditures  made by Company since October 31,
1997, made with Buyer's prior  approval,  will be added to the Final Net Current
Value of the Company as set out in paragraph 1.2.1 or 1.2.2 above.  Buyer hereby
acknowledges approval of the capital expenditures listed on Schedule 1.2.3.

The term "Final Net Current Value of the Company"  means the dollar value of the
amount by which the "Total  Current  Assets" as  recorded  on the Final  Balance
Sheet exceeds the "Total Liabilities" as recorded on the Final Balance Sheet.

1.3 Closing.  Consummation  of the  transactions  contemplated by this Agreement
(the "Closing") shall take place at the offices of the Company,  2895 West Main,
Newcastle, Wyoming 82701, contemporaneously with the execution of this Agreement
by all of the parties hereto (the "Closing Date") unless another time,  place or
date is agreed to by the Shareholders and the Buyer.

Company will resign.

Buyer duly and  validly  issued  certificates  representing  all of the  Company
Shares owned beneficially or of record by them, each such certificate to be duly

duly  executed in blank  sufficient  and in good form to properly  transfer such
Company   Shares  to  Buyer;   (b)  David  W.  Updike  will  deliver  Buyer  (i)

Shareholders  and Buyer shall have delivered to one another all other documents,
instruments  and  agreements as required under this  Agreement;  (d) Buyer shall
deliver  to the  Shareholders  the cash  purchase  price  payable  at Closing as

Shareholders; and (e) the Buyer and Shareholders will deliver to one another the

1.6 Termination of ESOP.

1.6.1 Termination.  The Company, by action of its Board of Directors,  agrees to
take such action as is necessary or  appropriate  to terminate  the ESOP as of a
date before the Closing date.  After the effective  date of  termination  of the
ESOP,  the  ESOP  shall  be  "frozen"  pending  distribution  of its  assets  to
participants  and their  beneficiaries.  No persons who are not  participants or

ESOP or receive benefits  thereunder,  and no distributions shall be made by the
ESOP except normal  distributions in the ordinary course of business pursuant to
the terms and provisions of the ESOP document.

1.6.2 IRS Determination  Letters.  Within 120 days after the Closing Date, Buyer
agrees to file a submission to formally request a determination  letter from the
Internal  Revenue Service (the "IRS") to the effect that the ESOP is a qualified
plan under Section 401(a) of the Internal  Revenue Code of 1986, as amended (the
"Code")  upon its  termination  and that the  trust  used to fund the ESOP  (the
"Trust")  is  tax  exempt  under  Section   501(a)  of  the  Code.  As  soon  as
administratively  practicable following receipt of a favorable IRS determination
letter,  the  administrator  of the  Trust  shall  effect  distributions  of all
remaining  assets from the Trust and,  thereafter,  it shall be liquidated.  The
individual  trustees of the Trust as of the Closing  Date agree to serve in such
capacity  until  such  time as the  Trust  has been  liquidated  and its  assets
completely  distributed  unless the Buyer, in its discretion,  elects to appoint
any successor  trustee.  The  Shareholders  hereby agree that the Buyer does not
assume  any  liability  or  obligation  with  respect  to the ESOP or Trust that
results  from,  relates to, or arises out of any act or omission by the Company,
the  trustees or any other  person or entity  occurring on or before the Closing
Date.

validly  existing and in good  standing  under the laws of the State of Wyoming,
has full requisite  corporate power and authority to carry on its business as it
is currently  conducted,  and to own and operate the properties  currently owned
and  operated by it, and is duly  qualified or licensed to do business and is in
good  standing  as a  foreign  corporation  authorized  to do  business  in  all
jurisdictions  in which the character of the  properties  owned or the nature of

necessary.

2.1.2  Agreements  Authorized and its Effect on Other  Obligations.  Each of the
Shareholders  has the legal capacity and requisite  power and authority to enter
into,  and perform  its  obligations  under this  Agreement  and the  Employment

Agreement,  the  Employment  Agreements and the  Non-Competition  Agreements are
valid  and  binding  obligations  of each of the  Shareholders  that are a party
thereto,  enforceable  against each of the Shareholders that are a party thereto
in accordance with their terms. The execution,  delivery and performance of this
Agreement, the Employment Agreements and the Non-Competition  Agreements by each
of the Shareholders that are a party thereto will not conflict with or result in
a violation  or breach of any term or  provision  of, nor  constitute  a default
under (i) the  Articles  of  Incorporation  or Bylaws of the Company or (ii) any
obligation,  indenture,  mortgage,  deed of  trust,  lease,  contract  or  other
agreement to which the Company or any of the Shareholders is a party or by which
the Company or any of the Shareholders or their respective properties are bound.

2.1.3 Capitalization.  The authorized  capitalization of the Company consists of
100,000 shares of Common Stock,  of which,  as of the date hereof,  6,166 shares
are  issued  and  outstanding  and  held  beneficially  and  of  record  by  the
Shareholders.  On the date  hereof,  the Company  does not have any  outstanding
options,  warrants, calls or commitments of any character relating to any of its
authorized  but unissued  shares of capital  stock.  All issued and  outstanding
shares of Common Stock are validly issued, fully paid and non-assessable and are
not subject to preemptive  rights (other than those preemptive  rights set forth
in Article VIII,  Section 3,  of the Company's  Bylaws,  which preemptive rights
have been waived by the Company). None of the outstanding shares of Common Stock
is  subject  to any  voting  trusts,  voting  agreement  or other  agreement  or
understanding with respect to the voting thereof,  nor is any proxy in existence
with respect thereto.

2.1.4  Ownership of the Company  Shares.  The  Shareholders  hold good and valid
title to the Company Shares set forth  opposite  their names on Schedule  1.1.2,
free and clear of all Encumbrances.  The Shareholders possess full authority and
legal right to sell,  transfer and assign the Company Shares to Buyer,  free and
clear of all  Encumbrances.  Upon transfer to Buyer by the  Shareholders  of the
Company  Shares,  Buyer  will  own the  Company  Shares  free  and  clear of all
Encumbrances.  There are no claims  pending or, to the  knowledge  of any of the
Shareholders,  threatened,  against the Company or any of the Shareholders  that
concern  or affect  title to the  Company  Shares,  or that  seek to compel  the
issuance of capital stock or other securities of the Company.

2.1.5  No  Subsidiaries.  Except  as set  forth on  Schedule 2.1.5,  there is no
corporation, partnership, joint venture, business trust or other legal entity in

intermediaries,  owns or holds beneficial or record ownership of the outstanding
voting securities.

2.1.6  Financial  Statements.  The Company has  delivered to Buyer copies of the

attached  hereto as Schedule  2.1.6 (the  "10/31  Balance  Sheet"),  and related
statements  of income,  with  appended  notes which are an integral part of such

Balance Sheet, or which have been thereafter acquired by the Company,  have been
collected or are  collectible  at the aggregate  recorded  amounts  thereof less
applicable reserves, which reserves are adequate.

does not have any  liabilities  or  obligations,  either  accrued,  absolute  or
contingent,  nor do any of the Shareholders  have any knowledge of any potential
liabilities  or  obligations  of the Company,  other than those (i) reflected or
reserved  against in the 10/31  Balance  Sheet or (ii)  incurred in the ordinary
course of  business  since the  Balance  Sheet  Date that  would not  materially

law), or (v)  obligates the Company to pay any benefits  solely as a result of a

and has no withdrawal  liability  with respect to any  multiemployer  plan,  and

ERISA.  There are no  claims,  lawsuits  or  regulatory  actions  that have been
asserted, instituted or threatened against any Employee Plan by any fiduciary or

Closing Date the Purchase Price for the Company Shares held by the ESOP is equal

Company or any of the  Shareholders  an intention to conduct the same, and there

                                 INDEMNIFICATION

4.1  Indemnification by the Sellers. In addition to any other remedies available
to Buyer under this Agreement,  or at law or in equity,  the Buyer, the Company,
their affiliates and their respective officers, directors, employees, agents and
stockholders   (collectively,   the  "Buyer  Indemnified  Parties"),   shall  be
indemnified  against  and with  respect to any and all claims,  costs,  damages,
losses, expenses, obligations,  liabilities, recoveries, suits, causes of action
and deficiencies, including interest, penalties and reasonable fees and expenses
of attorneys,  consultants  and experts  (collectively,  the "Damages") that the
Buyer  Indemnified  Parties shall incur or suffer,  which arise,  result from or
relate to any breach by any of the  Shareholders  (or the  failure of any of the
Shareholders to perform) their respective representations, warranties, covenants
or agreements  in this  Agreement or in any  schedule,  certificate,  exhibit or
other  instrument  delivered  to Buyer  by any of the  Shareholders  under  this
Agreement.

4.2 Indemnification by Buyer. In addition to any other remedies available to the
Shareholders  under  this  Agreement,  or at  law  or  in  equity,  Buyer  shall
indemnify,  defend and hold harmless each of the  Shareholders  against and with
respect to any and all  Damages  that such  indemnitees  shall  incur or suffer,
which  arise,  result  from or relate to any  breach  of, or failure by Buyer to
perform any of its representations,  warranties, covenants or agreements in this
Agreement or in any schedule, certificate, exhibit or other instrument furnished
or  delivered to either of the  Individuals  by or on behalf of Buyer under this
Agreement.

4.3.  Indemnification  Procedure.  If any party  hereto  discovers  or otherwise
becomes aware of an  indemnification  claim arising under Sections 4.1 or 4.2 of
this  Agreement,  such  indemnified  party  shall  give  written  notice  to the
indemnifying  party,  specifying  such claim,  and may  thereafter  exercise any
remedies available to such party under this Agreement;  provided,  however, that
the failure of any indemnified party to give notice as provided herein shall not
relieve the indemnifying party of any obligations  hereunder,  to the extent the
indemnifying party is not materially prejudiced thereby. Further, promptly after
receipt by an indemnified  party hereunder of written notice of the commencement
of any action or  proceeding  with respect to which a claim for  indemnification
may be made  pursuant to  Sections  4.1 or 4.2 hereof,  such  indemnified  party
shall,  if a claim in respect  thereof is to be made  against  any  indemnifying
party,  give written  notice to the latter of the  commencement  of such action;
provided,  however,  that the failure of any indemnified party to give notice as
provided  herein  shall not relieve the  indemnifying  party of any  obligations
hereunder,  to the extent the  indemnifying  party is not materially  prejudiced
thereby.  In case any such action is brought against an indemnified  party,  the
indemnifying party shall be entitled to participate in and to assume the defense
thereof,  jointly with any other indemnifying party similarly  notified,  to the
extent  that  it  may  wish,  with  counsel  reasonably   satisfactory  to  such
indemnified  party,  and after such notice from the  indemnifying  party to such
indemnified  party  of its  election  so to  assume  the  defense  thereof,  the
indemnifying  party shall not be liable to such indemnified  party for any legal
or other  expenses  subsequently  incurred by the latter in connection  with the
defense thereof unless the  indemnifying  party has failed to assume the defense
of such claim and to employ counsel reasonably  satisfactory to such indemnified
person.  An  indemnifying  party who elects not to assume the defense of a claim
shall not be liable for the fees and  expenses  of more than one  counsel in any
single  jurisdiction for all parties indemnified by such indemnifying party with
respect to such claim or with respect to claims  separate but similar or related
in  the  same  jurisdiction   arising  out  of  the  same  general  allegations.
Notwithstanding any of the foregoing to the contrary, the indemnified party will
be  entitled  to select its own  counsel  and  assume the  defense of any action
brought against it if the indemnifying  party fails to select counsel reasonably
satisfactory to the indemnified  party,  the expenses of such defense to be paid
by the indemnifying  party. No indemnifying  party shall consent to entry of any
judgment  or enter  into any  settlement  with  respect to a claim  without  the
consent  of the  indemnified  party,  which  consent  shall not be  unreasonably
withheld,  or unless such  judgment or settlement  includes as an  unconditional
term thereof the giving by the claimant or plaintiff to such  indemnified  party
of a release from all liability with respect to such claim. No indemnified party
shall consent to entry of any judgment or enter into any  settlement of any such
action, the defense of which has been assumed by an indemnifying party,  without
the consent of such indemnifying  party, which consent shall not be unreasonably
withheld or delayed.

4.3  Limitation on Damages.  Notwithstanding  anything in this  Agreement to the
contrary, the Buyer Indemnified Parties shall be indemnified for Damages only to
the extent of the Purchase  Price  Holdback  after  deducting all  Environmental
Assessment and Cleanup Costs pursuant to  Section 3.4.  The aggregate  amount of
any Damages owed by the Buyer to the Shareholders shall not exceed $1,000,000 in
the aggregate.

4.4  Exclusive  Remedy.  From and  after the date  hereof,  the  payment  of (i)
Environmental Assessments and Cleanup Costs pursuant to Section 3.4 and (ii) the
costs  of  indemnification  under  Sections  4.1  and  4.2,  as  limited  by the
provisions of Section 4.4,  shall be the exclusive remedies for monetary damages
that may be asserted under this Agreement or in connection with the transactions
contemplated  herein.  Notwithstanding  any provision of the contrary  contained
herein, each of the parties to this Agreement hereby waives any right to recover
special, punitive or exemplary damages for any claim asserted against the other.
Noting in this Section 4.5 shall limit the  availability of equitable  remedies,
such as specific performance, to enforce the provisions of this Agreement.
