                                 CONVERSION AGREEMENT


    This Agreement is made as of March 28, 1996, by and between MARQUEST
MEDICAL PRODUCTS, INC., a Colorado corporation (the "Company") and SCHERER
HEALTHCARE, INC., a Delaware corporation (the "Investor").

                                       RECITALS

    As evidenced by a Promissory Note dated June 15, 1993 in the original
principal amount of $4,042,900 (the "Convertible Note") the Company is indebted
to the Investor on the date hereof in the outstanding principal amount of
$1,851,600.  The Company is also indebted to the Investor in the amount of
$486,571 representing accrued and unpaid interest on the Convertible Note
through March 5, 1996 and in the amount of $376,330 for management fees owed by
the Company to the Investor through March 5, 1996.

    Pursuant to the terms in the Convertible Note, the Investor has the right
to convert the principal balance of the Convertible Note into common stock of
the Company at the conversion rate of $0.75 per share.  The Company has
requested that the Investor also convert accrued and unpaid interest on the
Convertible Note and the management fees owed by the Company to the Investor
through march 5, 1996 into common stock of the Company, and to induce the
Investor to do so, has agreed that all of the outstanding principal balance of
the Convertible Note, accrued and unpaid interest thereon and the unpaid
management fees shall be convertible into common stock of the Company at a
conversion price of $0.70 per share.

    The Investor has agreed to convert the principal and interest of the
Convertible Note and the unpaid management fees into common stock of the Company
at such conversion price.

    NOW THEREFORE, in consideration of the premises and the mutual promises
herein contained, the parties agree as follows:

    1.   Effective as of the date hereof, the Investor agrees to convert the
unpaid principal balance of the Convertible Note in the amount of $1,851,600,
unpaid interest thereon in the amount of $486,571 and unpaid management fees
owed by the Company in the amount of $376,330 into 3,877,859 shares of common
stock of the Company, par value $0.01 per share (the "Conversion Shares"), which
represents a conversion price of $0.70 per share (rounded up to the nearest
whole number of shares).  The Company shall, as soon as practical, issue and
deliver to the Investor a certificate for such shares, but such conversion shall
be deemed to have been made on the date of this Agreement and the Investor shall
be treated for all purposes as the record holder of such shares as of such date.
All shares issued to the Investor pursuant to such conversion shall be duly and
validly issued and fully paid and non-assessable. 

    2.   In connection with the conversion effectuated hereby, the Investor
represents and warrants to the Company as follows:

<PAGE>


         a.   The Investor is an "accredited investor" within the meaning of
Rule 501 under the Securities Act of 1933 and was not organized for the specific
purpose of acquiring the Conversion Shares.

         b.   The Investor has sufficient knowledge and experience in investing
in companies similar to the Company so as to be able to evaluate the risks and
merits of the Investor's conversion of indebtedness of the Company into the
Conversion Shares.

         c.   The Investor has had an opportunity to discuss the Company's
business, management, and financial affairs and prospects with the Company's
management personnel and to conduct such due diligence regarding the Company and
the Investor's investment in the Company as the Investor deems necessary.

         d.   The stock being acquired by the Investor as a result of the
conversion of indebtedness of the Company into the Conversion Shares is being
acquired by the Investor for the Investor's own account for purposes of
investment and not with a view to or for sale in connection with any
distribution or resale thereof.

         e.   The Investor understands that the Conversion Shares will not be
registered under the United States Securities Act of 1933, as amended, by reason
of its issuance in transactions exempt from the registration requirements of
such Act pursuant to Section 4(2) of such Act, (ii) the Conversion Shares must
be held indefinitely unless a subsequent disposition thereof is registered under
such act or is exempt from registration, and (iii) the Company will make a
notation on its transfer books to such effect.

         f.   The Investor understands that the following legend will be placed
on all stock certificates evidencing the Conversion Shares:

    "THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED
    UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE "ACT") OR ANY APPLICABLE
    STATE SECURITIES LAWS.  THE SHARES MAY BE SOLD OR TRANSFERRED ONLY IF THE
    SHARES ARE REGISTERED UNDER THE ACT AND APPLICABLE STATE SECURITIES LAWS OR
    MARQUEST MEDICAL PRODUCTS, INC. RECEIVES AN OPINION OF COUNSEL SATISFACTORY
    TO IT THAT AN EXEMPTION FROM REGISTRATION IS AVAILABLE."

    3.   The Company represents and warrants as follows:

         a.   This Agreement and the issuance of the Conversion Shares pursuant
to this Agreement (i) have been duly authorized by all necessary corporate
action, and (ii) does not and will not violate or contravene any provisions of
law or the Articles of Incorporation or Bylaws of the Company or any agreement
by which the Company or any of its assets are bound.  The Company is not
required to obtain the consent or approval of any person or entity, including,
without limitation, any governmental authority or its shareholders, to enter
into this Agreement 

                                          2

<PAGE>

and to consummate the transactions contemplated by this Agreement, except for
consents which have already been obtained.

         b.   When issued pursuant to this Agreement, the Conversion Shares

    IN WITNESS WHEREOF, this Agreement has been duly executed by the parties
hereto as of the date first above written.

    2.   THE LOANS.

         2.1    LOANS.

         (a)    From the date hereof through and until February 28, 2001 and
subject to the terms of this Agreement, from time to time Lender shall make
loans of up to $1,500,000 in total principal amount to Borrower for the purpose
of financing the Borrower's day to day business operations.  Advances made by
Lender under this

                                        - 6 -

<PAGE>

Section 2.1 are hereinafter collectively called the "Loans."  Subject to the
overall credit limitation of $1,500,000 in the aggregate (the "Total Loan
Commitment"), each Loan will be in increments of $250,000 or multiple integrals
thereof; provided that the first Loan shall be in the aggregate principal amount
of the Marquest Bridge Note and the last Loan extended hereunder may be in any
amount up to the remaining amount of the Total Loan Commitment.  Notwithstanding
any of the foregoing, the repayment or other satisfaction of any Loan shall not
obligate Lender to make any Loans to Borrower which, when added to the principal
amount of all previously issued Loans, whether or not paid, would exceed the
Total Loan Commitment.  Lender shall make each Loan available to Borrower at
Lender's principal office no later than 30 days from the date on which Lender
has received a written notice from Borrower requesting a Loan under this
Agreement, which notice must identify the principal amount of such requested
Loan and be accompanied by all certificates and other documents required to be
provided to Lender hereunder.

         (b)    Each of the Loans shall each be evidenced by a separate Note,
and interest on such Loans will accrue at the Prime Rate plus one and one-half
percent (1.5%) per annum, as determined on the date of issuance of each Note,
and adjusted thereafter on the first day of each calendar quarter; provided that
if the first day of any calendar quarter falls on a day other than a Business
Day, the adjustment to the interest rate shall be determined based upon the
Prime Rate in effect on the Business Day immediately preceding such date.
Principal and interest on such Loan will be payable as provided in such Note.

         2.2    INDEMNITY.  Borrower agrees to promptly indemnify and hold
harmless the Lender from and against any and all claims, liabilities, losses,
damages, actions and demands by any party against the Lender arising out of the
making, holding or administration of the Loans, allegations of any participation
by the Lender in the affairs of Borrower or allegations that the Lender has any
joint liability with the Borrower for any reason, allegations of violations of
Environmental Laws, environmental contamination or environmental liability, or
any claims against the Lender by any shareholder of the Borrower, unless, with
respect to the above, the Lender is finally and judicially determined to have
acted or failed to act with gross negligence or to have engaged in willful
misconduct.

         2.3    INTEREST SAVINGS CLAUSE.  Nothing contained in this Agreement
or in the Notes or in any of the other Loan Documents shall be construed to
permit Lender to receive at any time interest, fees or other charges in excess
of the amounts which Lender is legally entitled to charge and receive under any
law to which such interest, fees or charges are subject.  In no contingency or
event whatsoever shall the compensation payable to Lender by Borrower, howsoever
characterized or computed, hereunder

                                        - 7 -

<PAGE>

or under the Notes or under any other agreement or instrument evidencing or
relating to the Liabilities, exceed the highest rate permissible  under any law
to which such compensation is subject.  There is no intention that Lender shall
contract for, charge or receive compensation in excess of the highest lawful
rate, and, in the event it should be determined that any excess has been charged
or received, then, IPSO FACTO, such rate shall be reduced to the highest lawful
rate so that no amounts shall be charged which are in excess thereof; and Lender
shall apply such excess against the Liabilities then outstanding and, to the
extent of any amounts remaining thereafter, refund such excess to Borrower.

         2.4    COMMITMENT FEE.  From the date hereof through and including
February 28, 2001, Borrower shall pay Lender a commitment fee (the "Commitment
Fee"), calculated in each case on the basis of a 360-day year and actual days
elapsed, equal to one-half of one percent (1/2 of 1%) per annum of the aggregate
average daily unused amount of the Total Loan Commitment, payable on the first
day of each calendar quarter for the preceding quarter or portion thereof
(commencing on the first such date to occur following the date of this
Agreement).

         2.5    EXCHANGE OF MARQUEST BRIDGE NOTE.  Concurrently with the
execution of this Agreement, Borrower shall execute and deliver to Lender 
(a) one Note in the aggregate principal amount of all unpaid principal on the
Marquest Bridge Note (the "Initial Note") and (b) a check payable to the order
of Lender in the amount of all accrued but unpaid interest on the Marquest
Bridge Note (the "Interest Payment").  Concurrently with Lender's receipt of the
Initial Note and Interest Payment, Lender shall mark the Marquest Bridge Note
cancelled.  No amounts shall be payable by Lender to Borrower with respect to
the Note issued in exchange for the Marquest Bridge Note.

    3.   SECURITY INTEREST - COLLATERAL.

         3.1    SECURITY INTEREST.  As security for the Liabilities, Borrower
hereby grants to Lender a continuing, first priority lien on and security
interest in and to all of Borrower's Inventory and Equipment, whether now owned
or existing or hereafter acquired or arising or in which Borrower now has or
hereafter acquires any rights and wheresoever located, and all accessions to,
substitutions for and all replacements, products and proceeds (except to the
extent proceeds of any Inventory create accounts receivable, which accounts
receivable shall not constitute collateral) of the foregoing (all of the
foregoing sometimes herein referred to as "Collateral").

         3.2    MORTGAGE.  As additional security for the Liabilities, Borrower
shall execute and deliver the Mortgage to Lender, granting to Lender a lien on,
security title to and

                                        - 8 -

<PAGE>

security interest in the Realty and other property described therein.

         3.3    PERFECTION OF SECURITY INTEREST.  Until the termination of this
Agreement and the payment and satisfaction in full of all Liabilities, whichever
last occurs, Lender's security interest in the Collateral and the Realty, and
all products and proceeds thereof, shall continue in full force and effect.
Borrower shall perform any and all steps requested by Lender to perfect,
maintain and protect Lender's security interest in the Collateral and the
Realty, including, without limitation, executing and filing financing or
continuation statements, or amendments thereof, in form and substance
satisfactory to Lender; and delivering to Lender all documents or instruments
included in the Collateral and the Realty, the possession of which is necessary
or appropriate to perfect Lender's security interest therein.  Lender may file
one or more financing statements disclosing Lender's security interest under
this Agreement without Borrower's signature appearing thereon and Borrower shall
pay the costs of, or incidental to, any recording or filing of any financing
statements concerning the Collateral.  Borrower agrees that a carbon,
photographic, photostatic, or other reproduction of this Agreement or of a
financing statement is sufficient as a financing statement.

         3.4    RIGHT TO INSPECT; VERIFICATIONS.  Lender (or any person or
persons designated by it), in its sole discretion, shall have the right from
time to time to call at any place of business or property location of Borrower
at any reasonable time and, without hindrance or delay, to inspect the
Collateral and to audit, inspect and make copies and extracts from Borrower's
records and other data relating to the Collateral or the Realty, to Borrower's
business or to any other transactions between the parties hereto, including, but
not limited to, invoices and evidence of shipment and such other documents and
proof of delivery as Lender may reasonably require.

    4.   THE NOTES.

         4.1    CONVERSION.  Each Note shall be convertible, in whole or in
part, at the option of Lender into shares of capital stock of Borrower in
accordance with the terms and conditions in the Notes.  The initial "Conversion
Price" as described in Section 4.2 of each Note shall be Seventy Cents ($0.70)
per share, subject to adjustment as provided in Sections 4.5(a), (b) and (c) of
the Notes.

         4.2    REDEMPTION.  Each Note shall be redeemable by Borrower or by
Lender, as the case may be, in accordance with the terms and conditions in each
Note.

at law, in equity or otherwise:

Liabilities shall bear interest at the Default Rate until paid in full.

Event of Default (i) any commitment of Lender to loan funds to Borrower
hereunder shall automatically terminate, and (ii) all of the Liabilities shall
become immediately due and payable, whereupon the aggregate unpaid principal
balances of any and all interest accrued on the Notes, shall become forthwith

required by law relative thereto, all of which are hereby expressly waived by
Borrower, anything contained herein to the contrary notwithstanding.

         10.3   SET-OFF.  The right to set-off, without notice to Borrower, any
and all deposits at any time credited by or due from Lender to Borrower, and
whether or not matured or contingent.

         10.4   RIGHTS AND REMEDIES OF A SECURED PARTY.  All of the rights and
remedies of a secured party under the applicable Uniform Commercial Code or
under other applicable law, all of which rights and remedies shall be

law, in addition to any other rights and remedies contained in this Agreement,
and in any of the other Loan Documents.

         10.5   TAKE POSSESSION OF COLLATERAL.  The right to (a) enter upon the
premises of Borrower, or any other place or places where the Collateral is
located and kept, through self-help and without judicial process, without first
obtaining a final judgment or giving Borrower notice and opportunity for a
hearing on the validity of Lender's claim and without any obligation to pay rent
to Borrower, and remove the Collateral therefrom to the premises of Lender or
any agent of Lender, for such time as Lender may desire, in order to effectively
collect or liquidate the Collateral, and/or (b) require Borrower to assemble the
Collateral and make it available to Lender at a place to be designated by
Lender, in its sole discretion.

         10.6   SALE OF COLLATERAL.  The right to sell or to otherwise dispose
of all or any of the Collateral, at  public or private sale or sales, with such
notice as may be required by law, in lots or in bulk, for cash or on credit, all
as Lender, in its sole discretion, may deem advisable; such sales may be
adjourned from time to time with or without notice.  Lender shall have the right
to conduct such sales on Borrower's premises or elsewhere and shall have the
right to use Borrower's premises without charge for such sales for such time or
times as Lender may see fit.  Lender is hereby granted a license or other right
to use, without charge, Borrower's labels, patents, copyrights, rights of use of
any name, trade secrets, tradenames, trademarks, service marks and advertising
matter, or any property of a similar nature, as it pertains to the Collateral,
in advertising for sale and selling any Collateral and Borrower's rights under
all licenses and all franchise agreements shall inure to Lender's benefit.
Lender shall have the right to sell, lease or otherwise dispose of the
Collateral, or any part thereof, for cash, credit or any combination thereof,
and Lender may purchase all or any part of the Collateral at public or, if
permitted by law, private sale and, in lieu of actual payment of such purchase
price, may set off the amount of such price against the Liabilities, all free
from any right of redemption which is hereby expressly waived by Borrower.  The
proceeds realized from the sale of any Collateral shall be applied first to the
costs, expenses and attorneys' fees and expenses incurred by Lender for
collection and for acquisition, completion, protection, removal, storage, sale
and delivery of the

                                        - 24 -

<PAGE>

Collateral; second to interest due upon any of the Liabilities, all free from
any right of redemption which is hereby expressly waived by Borrower; and third
to the principal of the Liabilities.  The Borrower shall be liable to Lender and
shall pay to Lender on demand any deficiency which may remain after such sale,
disposition, collection or liquidation of the Collateral, and Lender in turn
agrees to remit to Borrower (or such other persons as are by law entitled
thereto) any surplus remaining after all Liabilities have been paid in full.  If
any of the Collateral shall require repairing, maintenance, preparation, or the
like, or is in process or other unfinished state, Lender shall have the right,
but shall not be obligated, to do such repairing, maintenance, preparation,
processing or completion of manufacturing for the purpose of putting the same in
such saleable form as Lender shall deem appropriate, but Lender shall have the
right to sell or dispose of such Collateral without such preparation, repair,
processing or the like.

         10.7   NOTICE.  BORROWER HEREBY WAIVES ANY AND ALL RIGHTS IT MAY HAVE
TO NOTICE OR HEARING PRIOR TO SEIZURE BY LENDER OF THE COLLATERAL WHETHER BY
WRIT OF POSSESSION OR OTHERWISE AND ANY REQUIREMENT THAT LENDER POST BOND IN ANY
SUCH PROCEEDING.  However, should Lender give notice, any notice given by Lender
of a sale, lease, other disposition of the Collateral or the Realty or any other
intended action by Lender, given to Borrower in the manner set forth in Section
12.8 below, ten (10) days prior to such proposed action, shall constitute
commercially reasonable and fair notice thereof to Borrower.

    11.  REPRESENTATIONS OF LENDER.

         11.1   Lender represents and warrants to Borrower with respect to the
Notes and the shares issuable upon conversion of the Notes (the "Purchased
Securities") as follows:

    (a)  Lender is acquiring the Purchased Securities solely for its own
account, with the intention of holding the same for investment, with no present
intention of dividing or allowing others to participate in this investment or of
reselling or otherwise participating, directly or indirectly, in a distribution
thereof; and it shall not make any sale, transfer or other disposition of the
Purchased Securities in violation of state or federal law.

    (b)  Lender understands that Marquest is under no obligation to register
the Purchased Securities for public sale or to comply with the conditions of
Rule 144 promulgated by the United States Securities and Exchange Commission
under the Securities Act of 1933 (the "Federal Act") or take any other action
necessary in order to make any exemption for the sale of the Purchased
Securities without registration available, and that Marquest has no present
intention of registering the Purchased Securities for public sale.

                                        - 25 -

<PAGE>

    (c)  Lender understands that the Purchased Securities will constitute
"restricted securities" under the Federal Act inasmuch as they are being or will
be acquired in a transaction not involving a public offering and that under the
Federal Act and applicable regulations thereunder may be resold without
registration under the Federal Act only in certain limited circumstances.

    (d)  Lender has such knowledge and experience in business and financial
matters that it is capable of evaluating the risks and merits associated with
the acquisition of the Purchased Securities and has had the opportunity to
review and evaluate financial and other information relating to the Borrower and
to obtain copies of such other information as deemed appropriate prior to
executing this Agreement.

    (e)  Lender acknowledges that any certificates representing shares of
common stock issuable upon conversion of any of the Notes will contain a legend
indicating that said shares have not been registered under the Federal Act or
any applicable state securities laws, and prohibiting further transfer, sale or
conveyance of such securities until such securities may, in the opinion of
counsel to the issuer, be so transferred, sold or conveyed without a violation
of any state or federal securities law.

    12.  MISCELLANEOUS.

         12.1   WAIVER.  Each and every right granted to Lender under this
Agreement, or any other document delivered hereunder or in connection herewith
or allowed  it by law or in equity, shall be cumulative and may be exercised
from time to time.  No failure on the part of Lender to exercise, and no delay
in exercising, any right shall operate as a waiver thereof, nor shall any single
or partial exercise by Lender of any right preclude any other or future exercise
thereof or the exercise of any other right.  No waiver by Lender of any Default
or Event of Default shall constitute a waiver of any subsequent Default or Event
of Default.

         12.2   SURVIVAL.  All representations, warranties and covenants made
herein shall survive the execution and delivery of all of the Loan Documents.
The terms and provisions of this Agreement shall continue in full force and
effect until all of the Liabilities have been paid in full and Lender has
terminated this Agreement in writing, whichever last occurs.

         12.3   NO ASSIGNMENT BY BORROWER.  No assignment hereof shall be made
by Borrower without the prior written consent of Lender.  Lender may assign, or
sell participations in, its right, title and interest herein and in the Loan
Documents at any time hereafter without notice to or consent of Borrower.

each of which when fully executed shall be an original, and all of said
counterparts taken together shall be deemed to constitute one and the same
agreement.

         12.5   EXPENSE REIMBURSEMENT.  Borrower agrees to reimburse Lender for
all of Lender's reasonable expenses incurred in connection with the development,
preparation, execution, delivery, modification, regular review and
administration of this Agreement, the Notes, and the other Loan Documents,
including audit costs, appraisal costs, the cost of searches, filings and filing
fees, taxes and the fees and disbursements of Lender's attorneys, and any
counsel retained by them, and all costs and expenses incurred by Lender
(including attorney's fees and disbursements) to:  (i) commence, defend or
intervene in any court proceeding; (ii) file a petition, complaint,  answer,
motion or other pleadings, or to take any other action in or with respect to any
suit or proceeding (bankruptcy or otherwise) relating to the Collateral, the
Realty or this Agreement, the Notes or any of the other Loan Documents; (iii)
protect, collect, lease, sell, take possession of, or liquidate any of the
Collateral or the Realty; (iv) attempt to enforce Lender's security interest in
the Collateral or the Realty or to seek any advice with respect to such
enforcement; and (v) enforce any of Lender's rights to collect any of the
Liabilities.  The Borrower also agrees to pay, and to save harmless Lender from
any delay in paying, any intangibles, documentary stamp and other taxes, if any,
which may be payable in connection with the execution and delivery of this
Agreement, the Notes or any of the other Loan Documents, or the recording of any
thereof, or in any modification hereof or thereof.

thereto or circumstance shall not be affected thereby and shall be enforced to

                           MARQUEST MEDICAL PRODUCTS, INC.
                               CONVERTIBLE SECURED NOTE
                                  DUE APRIL 1, 2001

    Date: _______________                       $__________


    1.   PROMISE TO PAY.  Marquest Medical Products, Inc., a corporation
incorporated under the laws of the State of Colorado (together with its
subsidiaries, if any, hereinafter collectively referred to as the "Company"),
for value received, hereby promises to pay, except as otherwise provided for
herein, to Scherer Capital, LLC (hereinafter called the "Holder"): (a) the
principal amount of _____________________________________ Dollars ($___________)
on April 1, 2001 (the "Maturity Date"); and (b) simple interest on the principal
amount hereof outstanding and unconverted from time to time commencing on the
date hereof, accruing at the "Prime Rate" (as such term is defined below) plus
one and one-half percent (1 1/2%), as determined on the date hereof and on the
first day of each calendar quarter thereafter, provided that if the first day of
a calendar quarter falls on a day other than a business day, such determination
shall be based on the Prime Rate in effect on the immediately preceding business
day.  Interest shall be payable quarterly on the 1st day of each April, July,
October and January throughout the term hereof, commencing on the date hereof.  
For purposes of this Note, the "Prime Rate" on any particular day is the
interest rate per annum published on such day in THE WALL STREET JOURNAL
(Eastern Edition) as the current prime corporate lending rate, or in the event
such Prime Rate is discontinued as a standard, a comparable 

<PAGE>

reference rate designated by Holder as a substitute therefor.  The principal
hereof and interest thereon shall be payable at the principal office of the
Holder (or at such other place as the Holder may reasonably designate) in such
coin or currency of the United States of America that at the time of payment
shall be legal tender for the payment of public or private debts in funds
collectible on the date which is prescribed herein for payment.

     In the event that payment is not made on the date prescribed for payment
herein, simple interest shall accrue on the aggregate amount due and payable
(including principal, interest or both, as the case may be) but remaining
unpaid, at the rate of eighteen percent (18%) per annum, (but in no event higher
than the maximum rate of interest permissible under applicable provisions of
law) from the date such amount becomes due and payable until the date of
payment.  In the event that the Holder is required to engage the services of an
attorney or to institute litigation to effect collection of the sums due
pursuant to this Note, the Company shall pay all reasonable costs of such
collection, including, without limitation reasonable attorneys' fees and court
costs not to exceed 15% of the outstanding principal and amount of, and the
accrued and unpaid interest on, the Note after default.

      The indebtedness evidenced hereby is secured by that certain Loan and
Security Agreement dated March 28, 1996, by and between Company and Holder (the
"Loan Agreement"). 

    2.   AUTHORIZED ISSUE.  This Note is one of the  Convertible Secured Notes
limited in the aggregate amount to One Million Five Hundred Thousand Dollars
($1,500,000) and referenced to in the Loan Agreement.  In addition to its rights
and remedies as set forth herein, the Holder shall have all of the rights and
remedies of the Lender under the Loan Agreement.  

    3.   EVENTS OF DEFAULT.  Upon the occurrence of an "Event of Default" as
such term is defined in the Loan Agreement, then, and in any such event and
without limiting its remedies as provided in the Loan Agreement, the Holder may,
upon delivery of a notice of any such Event of Default given to the Company,
declare the remaining unpaid and unconverted sums due under this Note to be
forthwith due and payable, whereupon the aggregate then unpaid and unconverted
principal amount of this Note, together with all accrued interest thereon, shall
become immediately due and payable without presentment, demand, protest or other
notice of any kind, all of which are hereby expressly waived.
    
    4.   CONVERSION.  At any time on or before the Maturity Date, the
outstanding principal amount of, and the accrued and unpaid interest on, this
Note shall be convertible into common stock, $0.01 par value, of Company (the
"Common Stock") at the option of 

                                         -2-

<PAGE>

the Holder in accordance with the following provisions of this Section 4.

         4.1  OPTIONAL CONVERSION.  Subject to and upon compliance with the
    other provisions of this Note and the provisions of this Section 4, the
    Holder shall have the right at the Holder's option to convert all or any
    portion of the outstanding principal of, and the accrued interest on, this
    Note into fully paid and nonassessable shares of Common Stock, at the
    Conversion Price (hereafter defined) in effect on the Conversion Date
    (hereafter defined), upon the terms hereinafter set forth.

         4.2  CONVERSION PRICE.  The outstanding principal amount of, and
    accrued interest on, this Note shall be convertible into the number of
    shares of Common Stock as is determined by multiplying the amount to be
    converted times a fraction, the numerator of which is $1.00 and the
    denominator of which is the Conversion Price in effect on the Conversion
    Date.  The Conversion Price at which shares of Common Stock shall be
    issuable upon conversion of this Note shall be Seventy Cents ($0.70)
    (subject to adjustment as provided below, hereafter the "Conversion
    Price").  The Conversion Price shall be subject to adjustment as set forth
    in Section 4.5 below.

         4.3  MECHANICS OF CONVERSION.  The Holder may exercise the conversion
    right specified in Section 4.1 above by written notice stating that the
    Holder elects to convert all or a specified portion of the outstanding
    principal amount of and interest on this Note.  Conversion shall be deemed
    to have been effected on the date when both notice of an election to
    convert and the original of this Note are delivered; any such date is
    referred to herein as the "Conversion Date".  As promptly as practicable
    thereafter Company shall issue and deliver to the Holder a certificate or
    certificates for the number of full shares of Common Stock to which the
    Holder is entitled rounded up to the next whole share as provided in
    Section 4.4 below in consideration of the delivery of the Note to the
    Company at such time.  If this Note is to be converted in part only,
    Company shall issue and deliver to the Holder contemporaneously therewith
    the original of this Note with an appropriate notation of the reduction in
    the principal amount so converted or a replacement note identical in all
    respects to this Note except as adjusted to reflect the outstanding
    principal amount thereof after giving effect to such conversion.  The
    person in whose name the certificate or certificates of Common Stock is to
    be issued shall be deemed to have become a holder of record of such Common
    Stock on the applicable Conversion Date.  Conversion of all 

                                         -3-

<PAGE>

    or any portion of the principal of this Note shall not affect Company's
    obligation to pay interest accrued through the date of conversion on the
    outstanding principal balance of this Note which is converted and on any
    remaining outstanding principal balance hereof.

         4.4  FRACTIONAL SHARES.  No fractional shares of Common Stock or scrip
    shall be issued upon conversion of this Note.  Instead of any fractional
    shares of Common Stock which would otherwise be issuable upon conversion of
    this Note, the number of full shares of Common Stock issuable upon
    conversion hereof shall be increased to the next highest number of whole
    shares.

         4.5  CONVERSION PRICE ADJUSTMENTS.  The Conversion Price and the
    number of shares of Common Stock issuable upon conversion (the "Conversion
    Shares") shall be subject to adjustment from time to time as follows:

              (a)  STOCK DIVIDENDS.  If the number of shares of Common Stock
         outstanding at any time after March 28, 1996 is increased by a stock
         dividend payable in shares of Common Stock or by a subdivision or
         split-up of shares of Common Stock, then immediately after the record
         date fixed for the determination of holders of Common Stock entitled
         to receive such stock dividend or the effective date of such
         subdivision or split-up, as the case may be, the Conversion Price
         shall be appropriately reduced and the number of Conversion Shares
         proportionately increased so that the Holder thereafter shall be
         entitled to receive the number of shares of Common Stock of Company
         which the Holder would have owned immediately following such action
         had this Note been then outstanding and converted immediately prior
         thereto.

              (b)  COMBINATION OF STOCK.  If the number of shares of Common
         Stock outstanding at any time after March 28, 1996 is decreased by a
         combination of the outstanding shares of Common Stock, then,
         immediately after the effective date of such combination, the
         Conversion Price shall be appropriately increased and the number of
         Conversion Shares proportionately decreased so that the Holder shall
         be entitled to receive the number of shares of Common Stock which the
         Holder would have owned immediately following such action had this
         Note been then outstanding and converted immediately prior thereto.

              (c)  REORGANIZATION.  In case of any capital reorganization of
         Company, or of any reclassification 

                                         -4-

         of the Common Stock, or in case of the consolidation of Company with
         or the merger of Company with or into any other corporation,
         partnership or other business entity in which Company is not the
         survivor, or any share exchange involving the Common Stock or of the
         sale, lease or other transfer of all or substantially all of the
         assets of Company to any other corporation, partnership or other
         business entity, or in the case of any distribution of cash (other
         than dividends not exceeding, in the aggregate, net income earned from
         December 31, 1995 to the date on which such dividend is declared) or
         other assets or of notes or other indebtedness of Company or any other
         securities of Company (except Common Stock) to the holders of Common
         Stock, this Note shall, after such capital reorganization,
         reclassification, consolidation, merger, share exchange, sale, lease
         or other transfer or such distribution, be convertible into the number
         of shares of stock or other securities or property to which a holder
         of the Common Stock issuable (at the time of such capital
         reorganization, reclassification, consolidation, merger, share
         exchange, sale, lease or other transfer or such distribution) upon
         conversion of this Note as the Holder would have been entitled to
         receive upon such capital reorganization reclassification,
         consolidation, merger, share exchange, sale, lease or other transfer
         or such distribution in place of (or in addition to, in the case of
         any such event after which Common Stock remains outstanding) the
         shares of Common Stock into which this Note would otherwise have been
         convertible; and in any such case, if necessary, the provisions set
         forth herein with respect to the rights and interests thereafter of
         the Holder shall be appropriately adjusted so as to be applicable, as
         nearly as may reasonably be, to any share of stock or other securities
         or property thereafter deliverable on the conversion of this Note. 
         The subdivision or combination of shares of Common Stock issuable upon
         conversion of this Note into a greater or lesser number of shares of
         Common Stock (whether with or without par value) shall not be deemed
         to be a reclassification of the Common Stock for the purposes of this
         subparagraph (c). 
 
              (d)  ROUNDING OF CALCULATIONS.  All calculations under this
         Section 4.5 shall be made to the nearest cent or to the nearest one
         hundredth (1/100th) of a share, as the case may be.

              (e)  TIMING OF ISSUANCE OF ADDITIONAL COMMON STOCK UPON CERTAIN
         ADJUSTMENTS.  In any case in which the provisions of this Section 4.5
         require that an adjustment shall become effective immediately after a
         record date for an event, Company may defer until the occurrence of
         such event issuing to the Holder hereof the additional shares of
         Common Stock or other property issuable or deliverable upon exercise
         by reason of the adjustment required by such event over and above the
         shares of Common Stock or other property issuable or deliverable upon
         such conversion before giving effect to such adjustment; PROVIDED,
         HOWEVER, that Company upon request shall deliver to the Holder a due
         bill or other appropriate instrument evidencing the Holder's right to
         receive such additional shares or other property, and such cash, upon
         the occurrence of the event requiring such adjustments.

         4.6  STATEMENT REGARDING ADJUSTMENTS.  Whenever the Conversion Price
    shall be adjusted as provided in Section 4.5, Company shall forthwith file,
    at the principal office of Company, a statement showing in detail the facts
    requiring such adjustment and the Conversion Price that shall be in effect
    after such adjustment, and Company shall also cause a copy of such
    statement to be sent by mail, first class postage prepaid, to the Holder at
    its address appearing on Company's records.  Each such statement shall be
    signed by Company's chief financial officer.  Where appropriate, such copy
    may be given in advance and may be included as part of a notice required to
    be mailed under the provisions of Section 4.7 below.

         4.7  NOTICE TO HOLDER.  In the event Company proposes to take any
    action of the type described in clause (a), (b) or (c) of paragraph 4.5
    above, Company shall give notice to Holder in the manner set forth in
    Section 4.6 above, which notice shall specify the record date, if any, with
    respect to any such action and the approximate date on which such action is
    to take place.  Such notice shall also set forth such facts with respect
    thereto as shall be reasonably necessary to indicate the effect of such
    action (to the extent such effect may be known at the date of such notice)
    on the Conversion Price and the number, kind or class of shares or other
    securities or property which shall be deliverable or purchasable upon the
    occurrence of such action or deliverable upon conversion of this Note.  In
    the case of any action which would require the fixing of a record date,
    such notice shall be given at least 10 days prior to the date so fixed, and
    in case of all other action, such notice shall be given at least 15 days
    prior to the taking of such proposed action.

    sufficient shares of Common Stock to provide for the conversion of this
    Note and set aside and keep available any other property deliverable upon
    conversion of this Note.

    be reserved for the purpose of conversion of this Note requires
    registration with or approval of any governmental authority under any
    Federal or state law before such shares or other securities may be validly
    issued or delivered upon conversion, then Company will in good faith and as

    as the case may be.

         4.11 VALID ISSUANCE.  All shares of Common Stock or other securities

    Company be duly and validly issued, fully paid and nonassessable and free

imposition of any lien, charge or encumbrance of any nature whatsoever on the

and clear of any liens, charges, encumbrances, security interests, claims,
easements, restrictions, options, leases (other than the Leases), covenants and
other rights, titles, interests or estates of any nature whatsoever except the

and Rents not covered by said Article 9, subject only to the Permitted
Encumbrances, all in accordance with the terms hereof.

    3.3  HAZARDOUS SUBSTANCES.  As used below, "Hazardous Substances" shall
mean and include all hazardous and toxic substances, wastes or materials, any
pollutants or contaminants (including, without limitation, asbestos and raw
materials which include hazardous constituents), or any other similar
substances, or materials which are included under or regulated by any local,
state or federal law, rule or regulation pertaining to environmental regulation,
contamination or clean-up, including, without limitation, "CERCLA", as amended,
or as may be amended from time to time, "RCRA", as amended, or as may be amended
from time to time, or state lien or state superlien or environmental clean-up
statutes (all such laws, rules and regulations being referred to collectively as
"Environmental Laws").  Trustor warrants, represents and agrees as follows:

         (a)(i)  The Mortgaged Property is not subject to any private or
    governmental lien, or to the best of Trustor's knowledge to any judicial or
    administrative notice or action, relating to Hazardous Substances or
    environmental problems, impairments or liabilities with respect thereto, or
    the direct or indirect violation of any Environmental Laws.

         (ii) No other personal or real property owned by Trustor is subject to
    any private or governmental lien, or to the best of Trustor's knowledge to
    any judicial or administrative notice or action, relating to Hazardous
    Substances or environmental problems, impairments or liabilities with
    respect thereto, or the direct or indirect violation of any Environmental
    Laws, which could materially and adversely affect the business, properties,
    financial position, results of operations or prospects of Trustor, and
    which Beneficiary could determine is likely to result in a future default
    under any covenant set forth in Section 7.8 of the Loan Agreement.

         (b)  Trustor shall not allow any Hazardous Substances to be stored,
    located, discharged, possessed, managed, processed or otherwise handled on
    the Mortgaged Property other than small quantities which are utilized in
    the ordinary course of business of the Mortgaged Property, and which are
    used and disposed of in a lawful manner, and Trustor shall comply with all
    Environmental Laws affecting the Mortgaged Property.

         (c)  Trustor shall immediately notify Beneficiary should Trustor
    become aware of (i) the existence of any Hazardous Substance in, on or
    beneath the Mortgaged Property or any other property owned by Trustor in

                                         -6-

<PAGE>

    violation of any Environmental Law with respect to the Mortgaged Property
    or any other property owned by Trustor, (ii) any "release" or threatened
    "release" (as defined in CERCLA and rules and regulations promulgated
    thereunder) of any Hazardous Substances on or from the Mortgaged Property
    or any other real property owned by Trustor, or (iii) any lien, action, or
    notice of the nature described in subparagraph (b) above.  Trustor shall,
    at its own cost and expense, take all actions as shall be necessary or
    advisable for the clean-up of the Mortgaged Property, including all
    removal, containment and remedial actions in accordance with all applicable
    Environmental Laws, and shall further pay or cause to be paid at no expense
    to Beneficiary all clean-up, administrative, and enforcement costs of
    applicable government agencies asserted against the Mortgaged Property or
    the owner thereof.  All costs, including, without limitation, those costs
    set forth above, damages, liabilities, losses, claims, expenses (including
    attorneys' fees and disbursements) which are incurred by Beneficiary,
    without requirement of waiting for the ultimate outcome of any litigation,
    claim or other proceeding, shall be paid by Trustor to Beneficiary as
    incurred within ten (10) days after notice from Beneficiary itemizing the
    amounts incurred to the date of such notice.

         (d)  Upon reasonable prior notice to Trustor, Beneficiary, its
    employees and agents, may from time to time (whether before or after the
    commencement of a nonjudicial or judicial proceeding) enter and inspect the
    Mortgaged Property for the purpose of determining the existence, location,
    nature and magnitude of any past or present release or threatened release
    of any hazardous substance into, onto, beneath or from the Mortgaged
    Property. Except in cases of emergency, any such inspection shall be
    conducted in a manner which does not unreasonably interfere with the
    operation of the Mortgaged Property.

    All warranties and representations contained in this Paragraph 3.3 shall be
deemed to be continuing and shall remain true and correct in all material
respects until the Indebtedness has been paid in full and any limitations period
expires.  Notwithstanding anything to the contrary contained herein or in any of
the other Security Documents, Trustor's agreements and Trustor's indemnification
of Beneficiary contained in Paragraph 3.3 shall survive the exercise of any
remedy by Beneficiary under any of the Security Documents, including foreclosure
(or deed in lieu thereof), even if, as a part of such foreclosure or deed in
lieu of foreclosure, the Indebtedness is satisfied in full, but only with
respect to liability or costs arising as a result of events occurring prior to
the date upon which Trustor is divested of title to the Mortgaged Property,
whether voluntarily, involuntarily or by operation of law. 


                                      Article 4

                                AFFIRMATIVE COVENANTS

    Trustor hereby unconditionally covenants and agrees with Beneficiary as
follows:

    4.1  PAYMENT AND PERFORMANCE.  Trustor will pay the Indebtedness due from
Trustor, as and when called for in the Security Documents, and on or before the
due dates thereof, and will perform all of the Obligations to be performed by
Trustor in full and on or before the dates same are to be performed.

                                         -7-

<PAGE>

    4.2  EXISTENCE.  Trustor will preserve and keep in full force and effect
its existence, rights, franchises and trade names.

    4.3  COMPLIANCE WITH LEGAL REQUIREMENTS.  Trustor will promptly and
faithfully comply with, conform to and obey all present and future Legal
Requirements in all material respects, whether or not same shall necessitate
structural changes in, improvements to, or interfere with the use or enjoyment
of the Mortgaged Property.

    4.4  SECOND DEED OF TRUST STATUS.  Trustor will protect the second priority
security deed status of this Deed of Trust and the other Security Documents and
will not place, or permit to be placed, or otherwise convey, mortgage,
hypothecate or encumber the Mortgaged Property with, any other lien or security
deed or interest of any nature whatsoever (statutory, constitutional or
contractual), regardless of whether same is allegedly or expressly inferior to
the title created by this Deed of Trust, without the prior written consent of
Beneficiary.  If any lien or security interest is asserted against the Mortgaged
Property, Trustor will, at its own cost and expense, (a) promptly pay the
underlying claim in full or take such other action so as to cause same to be
released or bonded to Beneficiary's satisfaction; and (b) within ten (10) days
from the date Trustor first has knowledge of such claim, lien or security
interest, give Beneficiary notice of such claim, lien or security interest. 
Such notice shall specify who is asserting such claim, lien or security interest
and shall detail the origin and nature of the underlying claim giving rise to
such asserted claim, lien or security interest.

    Trustor will observe and comply with all of the terms and conditions of the
Prior Deed of Trust and any and all documents evidencing or securing the
indebtedness secured thereby (the "Prior Loan Documents").  Trustor will
immediately forward to Beneficiary copies of all notices and other
correspondence received by Trustor under or relating to the Prior Loan
Documents.  Without Beneficiary's prior written consent, Trustor will not amend
or modify the Prior Loan Documents, or increase (or permit the increase of) the
indebtedness secured thereby to an amount greater than $ 100.00

    4.5  PAYMENT OF IMPOSITIONS.  Trustor will duly pay and discharge, or cause
to be paid and discharged, the Impositions not later than the due date thereof,
or the day prior to the day any fine, penalty, interest or cost may be added
thereto or imposed, or the day prior to the day any lien may be filed, for the
nonpayment thereof (if such day is used to determine the due date of the
respective item); provided, however, that Trustor may, if, to the extent and in
the manner permitted by law, (a) pay the Impositions in installments, whether or
not interest shall accrue on the unpaid balance of such Impositions, if such
installment payment would not create or permit the filing of a lien against the
Mortgaged Property, and (b) contest the payment of any Impositions in good faith
and by appropriate proceedings provided that:  (i) any such contests shall be
prosecuted diligently and in a manner not prejudicial to the rights, liens and
security interests of Beneficiary, (ii) if an Event of Default is then in
existence, Trustor shall deposit funds with Beneficiary or obtain a bond in form
and substance and with an issuing company reasonably satisfactory to Beneficiary
in an amount sufficient to cover any amounts which may be owing in the event the
contest may be unsuccessful (Trustor agreeing to make such deposit or obtain
such bond, as the case may be, within five (5) days after demand therefor and,
that, if made by payment of funds to Beneficiary, the amount so deposited shall
be disbursed in accordance with the resolution of the contest either to

                                         -8-

<PAGE>

Trustor or the adverse claimant), (iii) no contest may be conducted and no
payment may be delayed beyond the date on which the Mortgaged Property could be
sold for nonpayment, and (iv) Beneficiary may pay over to the taxing authority
entitled thereto any or all of the funds at any time when, in the opinion of
Beneficiary's counsel, the entitlement of such authority to such funds is
established.  Subject to Trustor's right to contest as provided for herein,
Trustor shall submit to Beneficiary copies of tax statements and paid tax
receipts evidencing the due and punctual payment of all real estate and personal
property taxes, charges and assessments levied upon or assessed or charged
against the Mortgaged Property on or before thirty (30) days of the delinquent
date of any such taxes.

    In the event of the passage of any state, federal, municipal or other
governmental law, order, rule or regulation, subsequent to the date hereof, in
any manner changing or modifying the laws now in force governing the taxation of
deeds to secure debt, or security agreements, or assignments of leases or debts
secured thereby or the manner of collecting such taxes so as to adversely affect
Beneficiary, Trustor will pay any such tax on or before the due date thereof. 
If Trustor fails to make such prompt payment or if, in the opinion of
Beneficiary, any such state, federal, municipal, or other governmental law,
order, rule or regulation prohibits Trustor from making such payment or would
penalize Beneficiary if Trustor makes such payment or if, in the opinion of
Beneficiary, the making of such payment might result in the imposition of
interest beyond the maximum amount permitted by applicable law, then the entire
balance of the Indebtedness and all interest accrued thereon shall, at the
option of Beneficiary, become immediately due and payable.

    4.6  REPAIR.  Trustor will keep the Mortgaged Property in first class order
and condition, and will make all repairs, replacements, renewals, additions,
betterments, improvements and alterations thereof and thereto, interior and
exterior, structural and nonstructural, ordinary and extraordinary, foreseen and
unforeseen, which are necessary or reasonably appropriate to keep same in such
order and condition.  Trustor will also use its best efforts to prevent any act
or occurrence which might materially impair the value or usefulness of the
Mortgaged Property for its intended usage, as set forth in the Security
Documents.  In instances where repairs, replacements, renewals, additions,
betterments, improvements or alterations are required in and to the Mortgaged
Property on an emergency basis to prevent loss, damage, waste or destruction
thereof, Trustor shall proceed to construct same, or cause same to be
constructed, notwithstanding anything to the contrary contained in Paragraph 5.2
hereinbelow; provided, however, that in instances where such emergency measures
are to be taken, Trustor will notify Beneficiary, in writing, of the
commencement of same and the measures to be taken, and when same are completed,
the completion date and the measures actually taken.

    4.7  INSURANCE.  (a) Trustor will obtain and maintain, or cause to be
obtained and maintained, insurance upon and relating to the Mortgaged Property,
insuring against personal injury and death, loss by fire and such other hazards,
casualties and contingencies (including business interruption insurance covering
loss of Rents and builder's all risk coverage) as are normally and usually
covered by extended coverage policies in effect where the Land is located and
such other risks as may be reasonably specified by Beneficiary, from time to
time, all in such amounts and with such insurers of recognized responsibility as
are reasonably acceptable to Beneficiary.  Each insurance policy issued in
connection therewith shall provide by way of endorsements, riders or otherwise
that (i) except as otherwise provided in Paragraph 4.7(c) below, proceeds will
be payable to

                                         -9-

<PAGE>

Beneficiary as its interest may appear, it being agreed by Trustor and
Beneficiary that such payments, less Beneficiary's expenses in collecting such
insurance proceeds, shall be applied, (A) to the restoration, repair or
replacement of the Mortgaged Property (hereinafter referred to as the "Work") if
all of the following conditions are satisfied within ninety (90) days from the
date of such damage or destruction:

         (I) In Beneficiary's reasonable opinion, the insurance proceeds are
    sufficient to pay all costs of the Work.  To the extent the proceeds are
    not sufficient to pay all costs of the Work, Beneficiary will permit
    Trustor to deposit such additional funds with Beneficiary or demonstrate to
    Beneficiary's reasonable satisfaction Trustor's ability to pay such
    additional costs of the Work;

         (II) Trustor has delivered to Beneficiary a construction contract for
    the Work in form and content reasonably acceptable to Beneficiary with a
    contractor reasonably satisfactory to Beneficiary; and

         (III) No Event of Default is continuing and no event has occurred and
    no facts exists which with notice or lapse of time, or both, would
    constitute an Event of Default;

or (B) if any of the conditions above is not satisfied, at Beneficiary's option,
either to the restoration, repair or replacement of the Mortgaged Property or
toward the payment of the Indebtedness; (ii) the coverage of Beneficiary shall
not be terminated, reduced or affected in any manner regardless of any breach or
violation by Trustor of any warranties, declarations or conditions in such
policy; (iii) no such insurance policy shall be cancelled, endorsed, altered or
reissued to effect a material change in coverage for any reason and to any
extent whatsoever unless such insurer shall have first given Beneficiary thirty
(30) days prior written notice thereof; and (iv) Beneficiary may, but shall not
be obligated to, make premium payments to prevent any cancellation, endorsement,
alteration or reissuance, and such payments shall be accepted by the insurer to
prevent same.  Beneficiary shall be furnished with a certificate of insurance
with respect to all liability insurance required by the terms of this Paragraph
4.7 and a certified copy (certified by the applicable insurer) of the original
of each other initial policy coincident with the execution of this Deed of Trust
and a certified copy (certified by the applicable insurer) of each renewal
policy not less than fifteen (15) days prior to the expiration of the initial or
each preceding renewal policy, together with receipts or other evidence that the
premiums thereon have been paid.  Trustor shall furnish to Beneficiary, on or
before thirty (30) days after the close of each of Trustor's fiscal year, a
statement certified by Trustor or a duly authorized officer of Trustor of the
amounts of insurance maintained in compliance with this Paragraph 4.7, of the
risks covered by such insurance, and of the insurance company or companies which
carry such insurance.

    (b) The delivery of any insurance policies hereunder shall constitute an
assignment of all unearned premiums as further security hereunder.  In the event
of the foreclosure of this Deed of Trust in extinguishment or partial
extinguishment of the Indebtedness, all right, title and interest of Trustor in
and to all insurance policies then in force shall pass to the purchaser or to
Beneficiary, as the case may be, and Beneficiary is hereby irrevocably appointed
by Trustor as attorney-in-fact for the Trustor to assign any such policy to said
purchaser or to Beneficiary, as the case may be, without accounting to Trustor
for any unearned premiums thereon.

                                         -10-

<PAGE>

    (c)  Notwithstanding the terms of subparagraph 4.7(a)(i) above, in the
event of a casualty causing less than One Hundred Thousand Dollars ($100,000.00)
of damage to the Mortgaged Property, and so long as no Event of Default is
continuing and no event has occurred or facts or conditions exists which with
the lapse of time or the giving of notice, or both, would in Beneficiary's
judgment constitute an Event of Default, then the insurance proceeds payable
with respect to such casualty may be paid directly to Trustor, to be used by
Trustor for the restoration and repair of the Mortgaged Property.

    4.8  APPLICATION OF PROCEEDS.

    If the proceeds of the insurance described in Paragraph 4.7 hereinabove are
to be used for the Work, such proceeds shall be paid out by Beneficiary from
time to time to Trustor (or, at the option of Beneficiary, jointly to Trustor
and the persons furnishing labor and/or material incident to the Work or
directly to such persons) as the Work progresses, subject to the following
conditions:  (a) if the cost of the Work estimated by Beneficiary shall exceed
$100,000.00, prior to the commencement thereof (other than Work to be performed
on an emergency basis to protect the Mortgaged Property or prevent interference
therewith), (i) an architect or engineer, approved by Beneficiary, shall be
retained by Trustor (at Trustor's expense) and charged with the supervision of
the Work, and (ii) Trustor shall have prepared, submitted to Beneficiary, and

Work; (b) each request for payment by Trustor shall be made on ten (10) days'
prior written notice to Beneficiary and shall be accompanied by a certificate to
be executed by the architect or engineer supervising the Work (if one is
required pursuant to Paragraph 4.8(a) hereinabove), otherwise by Trustor or an
executive officer of Trustor, stating, among such other matters as may be
reasonably required by Beneficiary, that:  (i) all of the Work completed has
been done in substantial compliance with the plans and specifications submitted
to Beneficiary; (ii) the sum requested is justly required to reimburse Trustor
for costs and expenses incurred by Beneficiary and for payments by Trustor to,
or is justly due to, the contractor, subcontractors, materialmen, laborers,
engineers, architects or other persons rendering services or materials for the
Work (giving a brief description of such services and materials); (iii) subject
to Paragraph 4.8 (f) hereinbelow, when added to all sums previously paid out by
Trustor, the sum requested does not exceed the value of the Work done to the
date of such certificate; and (iv) the amount of insurance proceeds remaining in
the hands of Beneficiary will be sufficient on completion of the Work to pay for
the same in full (giving, in such reasonable detail as the Beneficiary may
require, an estimate of the cost of such completion); (c) each request shall be
accompanied by waivers of lien and affidavits from Trustor's general contractor,
satisfactory in form and substance to Beneficiary, covering that part of the
Work for which payment or reimbursement was requested with respect to the
immediately preceding request for payment, and by a search prepared by a title
company or licensed abstractor or by other evidence satisfactory to Beneficiary
that there has not been filed with respect to the Mortgaged Property any
unbonded mechanic's lien or other lien, affidavit or instrument asserting any
lien or any lien rights with respect to the Mortgaged Property; (d) there has
not occurred any Event of Default since the hazard, casualty or contingency
giving rise to payment of the insurance proceeds; (e) in the case of the request
for the final disbursement, such request is accompanied by a copy of any

to render occupancy of the damaged portion of the Mortgaged Property lawful; and
(f) if, in Beneficiary's judgment, the amount of such insurance proceeds will
not be

                                         -11-

<PAGE>

sufficient to complete the Work (which determination may be made prior to or
during the performance of the Work), then Trustor shall deposit with
Beneficiary, immediately upon request therefor, an amount of money which, when
added to such insurance proceeds, will be sufficient, in Beneficiary's judgment,
to complete the Work.  If, upon completion of the Work, any portion of the
insurance proceeds has not been disbursed to Trustor (or one or more of the
other aforesaid persons) incident thereto, Beneficiary may, at Beneficiary's
option, disburse such balance to Trustor or apply such balance toward the
payment of the Indebtedness, whether or not then due.  Nothing herein shall be
interpreted to prohibit Beneficiary from (y) withholding from each such
disbursement ten percent (10%) (or such greater amount, if permitted or required
by any Legal Requirement) of the amount otherwise herein provided to be
disbursed, and from continuing to withhold such sum, until the Work has been
completed and Trustor has delivered to Beneficiary final lien waivers and
affidavits from Trustor's general contractor, satisfactory in form and substance
to Beneficiary, at which time the amount withheld shall be disbursed to, or at
the direction of, Trustor, or (z) applying at any time the whole or any part of
such insurance proceeds to the curing of any Event of Default.

    4.9  RESTORATION FOLLOWING CASUALTY.  If any act or occurrence of any kind
or nature, ordinary or extraordinary, foreseen or unforeseen (including any
casualty for which insurance was not obtained or obtainable), shall result in
damage to or loss or destruction of the Mortgaged Property, Trustor will give
notice thereof to Beneficiary immediately and, if so instructed by Beneficiary,
will promptly, at Trustor's sole cost and expense and regardless of whether the
insurance proceeds (if any) shall be sufficient for the purpose, commence and
continue diligently to completion to restore, repair, replace and rebuild the
Mortgaged Property in accordance with the provisions of Paragraph 4.8 and all
Legal Requirements as nearly as possible to its value, condition and character
immediately prior to such damage, loss or destruction.

    4.10 PRIOR DEED OF TRUST.  So long as the Prior Deed of Trust remains
outstanding, the disposition of insurance proceeds will be governed by the Prior
Deed of Trust; provided however, that (i) any insurance proceeds which by the
terms of the Prior Deed of Trust are to be disbursed to Trustor shall be
governed by, and disbursed pursuant to, this Deed of Trust, and (ii) if, and to
the extent, this Deed of Trust requires Trustor to maintain types of insurance
not required by the Prior Deed of Trust, or insurance in amounts greater than
required by the Prior Deed of Trust, Trustor shall maintain the types of
insurance, and in the amounts, required hereby.

    4.11 INSPECTION.  Trustor will permit Trustee and Beneficiary and their
agents, representatives and employees to inspect the Mortgaged Property at all
reasonable times.  

    4.12 HOLD HARMLESS.  Trustor will defend, at its own cost and expense, and
hold Beneficiary and Trustee harmless from any action, proceeding or claim
affecting the Mortgaged Property or the Security Documents, and all costs and
expenses incurred by Beneficiary or Trustee in protecting its interests
hereunder in such an event (including all court costs and attorneys' fees) shall
be borne by Trustor and secured hereby. 

    4.13 TAX AND INSURANCE ESCROW.  At Beneficiary's option, in order to
implement the provisions of Paragraphs 4.5 and 4.7 hereinabove, Trustor shall
pay to Beneficiary monthly, annually, or as otherwise directed by Beneficiary,
an amount (together with interest earned thereon, the "Escrowed Sums") equal to
the sum of (a) the annual Impositions (estimated by Beneficiary, wherever

                                         -12-

<PAGE>

necessary) to become due for the tax year during which such payment is so
directed and (b) the insurance premiums for the same year for those insurance
policies as are required hereunder.  If Beneficiary determines that any amounts
theretofore paid by Trustor are insufficient for the payment in full of such
Impositions and insurance premiums, Beneficiary shall notify Trustor of the
increased amounts required to provide a sufficient fund, whereupon Trustor shall
pay to Beneficiary within thirty (30) days thereafter the additional amount as
stated in Beneficiary's notice.  The Escrowed Sums shall be held by Beneficiary
in an interest-bearing account (with all interest earned on such account being
credited to such account) and may be commingled with Beneficiary's other funds. 
Upon assignment of this Deed of Trust, Beneficiary shall pay over the balance of
the Escrowed Sums then in its possession to its assignee whereupon, provided the
assignee expressly assumes Beneficiary's obligations hereunder with respect such
Escrowed Sums, the Beneficiary shall then become completely released from all
liability with respect thereto.  Within ninety-five (95) days following the full
payment of the Indebtedness (other than a full payment of the Indebtedness as a
consequence of a foreclosure or conveyance in lieu of foreclosure of the liens
and security interests securing the Indebtedness) or at such earlier time as
Beneficiary may elect, the balance of the Escrowed Sums in its possession shall
be paid over to Trustor and no other party shall have any right or claim
thereto.  If no Event of Default shall have occurred and be continuing
hereunder, the Escrowed Sums shall, at the option of Beneficiary, either (i) be
repaid to Trustor in sufficient time to allow Trustor to satisfy Trustor's
obligations under the Security Documents to pay the Impositions and the required
insurance premiums or (ii) be paid directly to the Governmental Authority and
the insurance company entitled thereto on or before the date such payments are
due.  If an Event of Default shall have occurred and be continuing hereunder,
however, Beneficiary shall have the additional option of crediting the full
amount of the Escrowed Sums against the Indebtedness.  Notwithstanding anything
to the contrary contained in this Paragraph 4.13 or elsewhere in this Deed of
Trust, Beneficiary hereby reserves the right to waive the payment by Trustor to
Beneficiary of the Escrowed Sums, and, in the event Beneficiary does so waive
such payment, it shall be without prejudice to Beneficiary's rights to insist,
at any subsequent time or times, that such payments be made in accordance
herewith.  The provisions of this Paragraph 4.13 are not intended to contravene
any applicable requirements of the laws of the State of Colorado, and from time
to time the provisions of this Paragraph 4.13 shall be deemed modified as
necessary to be in conformance with the laws of the State of Colorado (provided
that the provisions of this Paragraph 4.13 shall be controlling to the extent
any contrary requirements of Colorado law may be waived, and Trustor hereby
waives those requirements of Colorado law to the fullest extent allowed).

                                      Article 5

                                  NEGATIVE COVENANTS

    Trustor hereby covenants and agrees that until the entire Indebtedness
shall have been paid in full and all of the Obligations shall have been fully
performed and discharged:

    5.1  USE VIOLATIONS.  Trustor will not use, maintain, operate or occupy, or
allow the use, maintenance, operation or occupancy of, the Mortgaged Property in
any manner or for any purpose which (a) violates any Legal Requirement, Lease or
Major Agreement, (b) constitutes a public or private nuisance, or (c) makes
void, voidable or cancelable, or increases the premium of, any insurance then in
force with respect thereto.


                                         -13-

<PAGE>

    5.2  ALTERATIONS.  Trustor will not commit (and will not permit) any waste
of the Mortgaged Property and will not (subject to the provisions of Paragraphs
4.6 and 4.9 hereinabove), without the prior written consent of Beneficiary, make
or permit to be made any alterations or additions to the Mortgaged Property.

    5.3  REPLACEMENT OF FIXTURES AND PERSONALTY.  Trustor will not, without the
prior written consent of Beneficiary, permit any of the Fixtures or Personalty
to be removed at any time from the Land or Improvements unless the removed item
is removed temporarily for maintenance and repair or, if removed permanently, is
replaced by an article of equal suitability and value, owned by Trustor, free
and clear of any lien or security interest except such lien or security interest
as may be first approved, in writing, by Beneficiary.

    5.4  ENCUMBRANCE UPON MORTGAGED PROPERTY.  Trustor shall not, without the
prior written consent of Beneficiary, create, place or permit to be created or
placed or through any act or failure to act, acquiesce in the placing of, or
allow to remain, any deed of trust, mortgage, security deed, pledge, lien
(statutory, constitutional or contractual), security interest, encumbrance or
charge on, or conditional sale or other title retention agreement, regardless of
whether same are expressly subordinate to the liens of the Security Documents,
with respect to the Mortgaged Property, other than the Permitted Encumbrances.

                                      Article 6

                                  EVENTS OF DEFAULT

    The term "Event of Default", as used in the Security Documents, shall mean
the occurrence or happening, at any time and from time to time, of any one or
more of the following:

    6.1  FAILURE IN PAYMENT OF INDEBTEDNESS.  If Trustor shall fail, refuse or
neglect to pay, in full, any installment or portion of the Indebtedness due from
Trustor as and when the same shall become due and payable, whether at the due
date thereof stipulated in the Security Documents, or at a date fixed for
prepayment, or by acceleration or otherwise, and such failure, refusal or
neglect continues for a period of five (5) days.

    6.2  DISPOSITION OF MORTGAGED PROPERTY.  If Trustor sells, leases,
exchanges, assigns, conveys, transfers or otherwise disposes of (herein
collectively called "Disposition") all or any portion of the Mortgaged Property
(or any interest therein), without the prior written consent of Beneficiary.  It
is expressly agreed that in connection with determining whether to grant or
withhold such consent, Beneficiary may (but is not obligated to), among other
things, (i) consider the creditworthiness of the party to whom such Disposition
will be made and its management ability with respect to the Mortgaged Property,
(ii) consider whether or not the security for repayment of the Indebtedness and
the performance of the Obligations, or Beneficiary's ability to enforce its
rights, remedies and recourses with respect to such security, will be impaired
in any way by the proposed Disposition, (iii) require that Beneficiary be
reimbursed for all costs and expenses incurred by Beneficiary in investigating
the creditworthiness and management ability of the party to whom such
Disposition will be made and in determining whether Beneficiary's security will
be impaired by the proposed Disposition, (iv) require the payment to Beneficiary
of a transfer fee to cover the cost of documenting the Disposition in its
records, (v) require the payment of its attorney's fees incurred in connection
with such Disposition, (vi) require the express assumption, from and after the
date of such Disposition, of Trustor's obligation to pay the Indebtedness

                                         -14-

<PAGE>


and perform the Obligations by the party to whom such Disposition will be made
(with or without the release of Trustor from liability for such Indebtedness and
Obligations), (vii) require the execution of Assumption Agreements, Modification
Agreements, Supplemental Security Documents and Financing Statements
satisfactory in form and substance to Beneficiary, and (viii) require
endorsements (to the extent available under applicable law) to any existing
mortgagee title insurance policies insuring this Deed of Trust and the security
interests covering the Mortgaged Property.

    6.3  ENCUMBRANCE UPON MORTGAGED PROPERTY.  If the Trustor shall, without
the prior written consent of Beneficiary, create, place or permit to be created
or placed, or through any act or failure to act, acquiesce in the placing of, or
allow to remain, any mortgage, security deed, pledge, lien (statutory,
constitutional or contractual), security interest, encumbrance or charge on, or
conditional sale or other title retention agreement, regardless of whether same
are expressly subordinate to the liens of the Security Documents, with respect
to the Mortgaged Property, other than the Permitted Encumbrances.

    6.4  DEFAULT IN PRIOR LOAN DOCUMENTS.  If an event of default shall occur
under the Prior Deed of Trust or any other Prior Loan Document, and not be cured
within the applicable grace or cure period, if any.

    6.5  FORECLOSURE OF OTHER LIENS.  If the holder of any lien or security
interest or deed on the Mortgaged Property (without hereby implying
Beneficiary's consent to the existence, placing, creating or permitting of any
such lien or security interest or deed) institutes foreclosure or other
proceedings for the enforcement of its remedies thereunder.

    6.6  DEFAULT IN LOAN AGREEMENT OR OTHER DOCUMENTS.  If an event of default
shall occur under the Loan Agreement or any other Security Document (even though
not listed as an Event of Default hereunder), and the same is not cured within
the applicable cure period, if any.

    6.7  NOTICE OF DEFAULT NOT REQUIRED.  Except as otherwise expressly
provided herein or in the other Security Documents, no notice of default shall
be required, and without Beneficiary's prior written consent, no right to cure
shall be granted for the Events of Default described hereinabove.


                                      Article 7

                                BENEFICIARY'S REMEDIES

    7.1  REMEDIES.  If an Event of Default shall occur, Beneficiary may, at its
sole election, by or through Trustee or otherwise, exercise any or all of the
following rights, remedies and recourses:

         (a)  ACCELERATION:  Declare the Principal Balance (defined hereby as
meaning the then unpaid principal balance on the Notes), the accrued interest
and any other accrued but unpaid portion of the Indebtedness to be immediately
due and payable, without further notice, presentment, protest, demand or action
of any nature whatsoever (each of which hereby is expressly waived by Trustor),
whereupon the same shall become immediately due and payable, time being of the
essence in this Deed of Trust.

         (b)  TERMINATION OF LICENSE AND/OR ENTRY ON MORTGAGED PROPERTY: 
Demand that Trustor shall forthwith surrender to Beneficiary the actual
possession of the Mortgaged Property,

                                         -15-

<PAGE>

and/or terminate the license granted Trustor in Paragraph 10.2 hereof to receive
the Rents and, to the extent permitted by law, enter and take possession of all
of the Mortgaged Property without the appointment of a receiver, or an
application therefor, and exclude Trustor and its agents and employees wholly
therefrom, and have joint access with Trustor to the books, papers and accounts
of Trustor.

         If Trustor shall for any reason fail to surrender or deliver the
Mortgaged Property or any part thereof after such demand by Beneficiary,
Beneficiary may obtain a judgment or decree conferring upon Beneficiary the
right to immediate possession or requiring Trustor to deliver immediate
possession of the Mortgaged Property to Beneficiary, and Trustor hereby
specifically covenants and agrees that Trustor will not oppose, contest or
otherwise hinder or delay Beneficiary in any action or proceeding by Beneficiary
to obtain such judgment or decree.  Trustor will pay to Beneficiary, upon
demand, all expenses of obtaining such judgment or decree, including reasonable
compensation to Beneficiary, its attorneys and agents, and all such expenses and
compensation shall, until paid, become part of the Indebtedness and shall be
secured by this Deed of Trust.

         Upon every such entering upon or taking of possession, Beneficiary may
hold, store, use, operate, manage and control the Mortgaged Property and conduct
the business thereof, and, from time to time, (i) make all necessary and proper
maintenance, repairs, renewals, replacements, additions, betterments and
improvements thereto and thereon and purchase or otherwise acquire additional
fixtures, personalty and other property (ii) insure or keep the Mortgaged
Property insured (iii) manage and operate the Mortgaged Property and exercise
all the rights and powers of Trustor to the same extent as Trustor could in its
own name or otherwise act with respect to the same and (iv) enter into any and
all agreements with respect to the exercise by others of any of the powers
herein granted to Beneficiary, all as Beneficiary from time to time may
determine to be in its best interest.  Whether or not Beneficiary has obtained
possession of the Mortgaged Property, upon the termination of Trustor's license
to receive the Rents, Beneficiary may collect, sue for and receive all the Rents
and other issues, profits and revenues from the Mortgaged Property, including
those past due as well as those accruing thereafter.  Anything in this Deed of
Trust to the contrary notwithstanding, Beneficiary shall not be obligated to
discharge or perform the duties of the landlord to any tenant or lessee under
any Lease, discharge or perform any obligations under any Major Agreement, or
incur any liability as the result of any exercise by Beneficiary of its rights
under this Deed of Trust, and Beneficiary shall be liable to account only for
the Rents actually received by Beneficiary.

         Whether or not Beneficiary takes possession of the Mortgaged Property,
Beneficiary may make, modify, enforce, cancel or accept surrender of any Major
Agreement and Lease, remove and evict any tenant, increase or decrease Rents
under any Lease, appear in and defend any action or proceeding purporting to
affect the Mortgaged Property, and perform and discharge each and every
obligation, covenant and agreement of Trustor contained in any Major Agreement
or any Lease.  Neither the entering upon and taking possession of the Mortgaged
Property, nor the collection of any Rents and the application thereof as
aforesaid, shall cure or waive any Event of Default theretofore or thereafter
occurring, or affect any notice of an Event of Default hereunder or invalidate
any act done pursuant to any such notice.  Beneficiary shall not be liable to
Trustor, anyone claiming under or through Trustor, or anyone having an interest
in the Mortgaged Property by reason of anything done or left undone by
Beneficiary hereunder.  Nothing contained in this Paragraph 7.1(b) shall

                                         -16-

<PAGE>

require Beneficiary to incur any expense or do any act.  If the Rents are not
sufficient to meet the costs of taking control of and managing the Mortgaged
Property and/or collecting the Rents, any funds expended by Beneficiary for such
purposes shall become a part of the Indebtedness secured by this Deed of Trust. 
Such amounts, together with interest at the Default Rate provided for under the
Loan Agreement and attorneys' fees, if applicable, shall be immediately due and
payable.  Notwithstanding Beneficiary's continuance in possession or receipt and
application of Rents, Beneficiary shall be entitled to exercise every right
provided for in this Deed of Trust or by law upon or after the occurrence of an
Event of Default.  Any of the actions referred to in this Paragraph 7.1(b) may
be taken by Beneficiary at such time as Beneficiary is so entitled, without
regard to the adequacy of any security for the Indebtedness hereby secured.

         In the event that all such interest, deposits and principal
installments and other sums due under any of the terms, covenants, conditions
and agreements of this Deed of Trust shall be paid and all Events of Default
shall be cured, and as a result thereof Beneficiary surrenders possession of the
Mortgaged Property to Trustor, the same right herein given to Beneficiary shall
continue to exist if any subsequent Events of Default shall occur.

         (c)  FORECLOSURE.  Execute a written notice of such Event of Default
and of its election to cause the Mortgaged Property to be sold to satisfy the
Indebtedness and the Obligations.  As a condition precedent to any such sale,
Trustee shall give and record such notice of default and election to sell as the
law then requires.  When the minimum period of time required by law after such
notice has elapsed, or at any time thereafter, at Beneficiary's sole discretion,
Trustee, without notice to or demand upon Trustor except as required by law,
shall sell the Mortgaged Property at the time and place of sale fixed by it in
the notice of sale, at one or several sales, either as a whole or in separate
parcels and in such manner and order, all as Beneficiary in its sole discretion
may determine, at public auction to the highest bidder for cash, in lawful money
of the United States, payable at time of sale subject, however, to the
provisions of Paragraph 7.10 below.  Neither Trustor nor any other person or
entity other than Beneficiary shall have the right to direct the order in which
the Mortgaged Property is sold.  Subject to any requirements and limits imposed
by law, Trustee may from time to time postpone sale of all or any portion of the
Mortgaged Property by public announcement at such time and place of sale.  Upon
any sale and the expiration of applicable redemption periods, if any, and unless
the Trustor has redeemed, Trustee shall execute and deliver to the holder of the
certificate of purchase or last redemption certificate, as the case may be, a
deed conveying the Mortgaged Property or portion thereof so sold, in the manner
and form required by law, whereupon such purchaser or purchasers shall be let
into immediate possession.  In the event of a sale or other disposition of the
Mortgaged Property, or any part thereof, whether made under the power of sale
herein granted or under or by virtue of judicial proceedings or of a judgment or
decree of foreclosure and sale, and the execution of a deed or other conveyance
pursuant thereto, the recitals in the deed of any matters or facts shall be
conclusive proof of the truthfulness thereof.  Any person, including Trustee,
Trustor or Beneficiary may purchase at the sale.  Nothing in this paragraph
dealing with foreclosure procedures or specifying particular actions to be taken
by Beneficiary or by Trustee or any similar officers shall be deemed to
contradict or add to the requirements and procedures now or hereafter specified
by Colorado law, and any such inconsistency shall be resolved in favor of
Colorado law applicable at the time of foreclosure.

                                         -17-

<PAGE>

         Beneficiary, may, in addition to and not in abrogation of the rights
covered under the immediately preceding subparagraph, or elsewhere in this
Article 7, either with or without entry or taking possession as herein provided
or otherwise, proceed by a suit or suits in law or in equity or by any other
appropriate proceeding or remedy (i) to enforce payment of the Notes or the
performance of any term, covenant, condition or agreement of this Deed of Trust
or any other right and (ii) to pursue any other remedy available to it, all as
Beneficiary at its sole discretion shall elect.

         (d)  RECEIVER:  Beneficiary, upon application to a court of competent
jurisdiction, shall be entitled as a matter of strict right, ex parte and
without notice and without regard to the adequacy or value of any security for
the Indebtedness or the solvency of any party bound for its payment, to the
appointment of a receiver to take possession of and to operate the Mortgaged
Property and to collect and apply the incomes, rents, issues, profits and
revenues thereof.  The receiver shall have all of the rights and powers
permitted under the laws of the State of Colorado.  Trustor will pay to
Beneficiary upon demand all expenses, including receiver's fees, attorneys'
fees, costs and agent's compensation, incurred pursuant to the provisions of
this Paragraph, and any such amounts paid by Beneficiary shall be added to the
Indebtedness and shall be secured by this Deed of Trust.

         (e)  PERFORMANCE BY BENEFICIARY:  Pay, perform or observe any term,
covenant or condition of this Deed of Trust not paid, performed or observed by
Trustor, and all payments made or costs or expenses incurred by Beneficiary in
connection therewith shall be secured hereby and shall be, upon demand,
immediately repaid with interest thereon at the Default Rate provided in the
Loan Agreement.  Beneficiary shall be the sole judge of the necessity for any
such actions and of the amounts to be paid.  Beneficiary is hereby empowered to
enter and to authorize others to enter upon the Mortgaged Property or any part
thereof for the purpose of performing or observing any such defaulted term,
covenant or condition without thereby becoming liable to Trustor or any person
in possession holding under Trustor.

         (f)  JUDICIAL FORECLOSURE; SPECIFIC PERFORMANCE:  Commence and
maintain an action or actions in any court of competent jurisdiction to
foreclose this Deed of Trust or to obtain specific enforcement of the covenants
of Trustor hereunder, and Trustor agrees that such covenants shall be
specifically enforceable by injunction or any other appropriate equitable remedy
and that for the purposes of any suit brought under this subparagraph, Trustor
waives the defense of laches and any applicable statute of limitations.

         (g)  OTHER:  Exercise any and all other rights, remedies and recourses
granted under the Security Documents (including, without limitation, those set
forth in Articles 9 and 10 hereinbelow) or now or hereafter existing in equity,
at law, by virtue of statute or otherwise.

    7.2  SEPARATE SALES.  Trustor, for itself and for all parties claiming
through or under Trustor, and for all parties who may acquire a lien on or
interest in the Mortgaged Property, hereby waives all rights to have the
Mortgaged Property and/or any other property which is now or later may be
security for the Indebtedness and Obligations ("Other Property") marshalled upon
any foreclosure of this Deed of Trust or on a foreclosure of any other security
for any of the Indebtedness or Obligations.  Trustee, if so directed by
Beneficiary at Beneficiary's election, shall have the right to sell, and any
court in which foreclosure proceedings may be brought shall have the right to
order a sale

                                         -18-

<PAGE>

of, the Mortgaged Property and any or all of the Other Property as a whole or in
separate parcels, in any order that Beneficiary may designate.  The Mortgaged
Property may be sold in one or more parcels and in such manner and order as
Beneficiary, in its sole but reasonable discretion, may elect, it being
expressly understood and agreed that the right of sale arising out of any Event
of Default shall not be exhausted by any one or more sales.

    7.3  REMEDIES CUMULATIVE, CONCURRENT AND NONEXCLUSIVE.  Beneficiary shall
have all rights, remedies and recourses granted in the Security Documents and
available at law or equity (including specifically those granted by the Uniform
Commercial Code in effect in Colorado and applicable to the Mortgaged Property,
the Leases, or any portion thereof); and same (a) shall be cumulative and
concurrent, (b) may be pursued separately, successively or concurrently against
Trustor or others obligated under the Notes, or against the Mortgaged Property,
or against any one or more of them, at the sole discretion of Beneficiary, (c)
may be exercised as often as occasion therefor shall arise, it being agreed by
Trustor that the exercise or failure to exercise any of same shall in no event
be construed as a waiver or release thereof or of any other right, remedy or
recourse, and (d) are intended to be, and shall be, nonexclusive.

    7.4  NO CONDITIONS PRECEDENT TO EXERCISE OF REMEDIES.  Neither Trustor nor
any other person hereafter obligated for payment of all or any part of the
Indebtedness, or fulfillment of all or any of the Obligations, shall be relieved
of such obligation by reason of (a) the failure of Beneficiary to comply with
any request of Trustor or of any other person so obligated, to foreclose this
Deed of Trust or to enforce any provisions of the other Security Documents, (b)
the release, regardless of consideration, of the Mortgaged Property or the
addition of any other property to the Mortgaged Property, (c) any agreement or
stipulation between any subsequent owner of the Mortgaged Property and
Beneficiary extending, renewing, rearranging or in any other way modifying the
terms of the Security Documents without first having obtained the consent of,
given notice to or paid any consideration to Trustor or such other person, and
in such event, Trustor and all such other persons shall continue to be liable to
make payment according to the terms of any such extension or modification
agreement unless expressly released and discharged, in writing, by Beneficiary,
or (d) by any other act or occurrence, save and except the complete payment of
the Indebtedness and the complete fulfillment of all of the Obligations.

    7.5  RELEASE OF AND RESORT TO COLLATERAL.  Beneficiary may release,
regardless of consideration, any part of the Mortgaged Property without, as to
the remainder, in any way impairing, affecting, subordinating or releasing the
conveyance, lien, encumbrance or security interests created in or evidenced by
the Security Documents or their stature as a first and prior security deed,
lien, encumbrance or security interest in and to the Mortgaged Property.  For
payment of the Indebtedness, Beneficiary may resort to any security therefor
held by Beneficiary in such order and manner as Beneficiary may elect.

    7.6  WAIVER OF APPRAISEMENT, VALUATION, ETC.  Trustor agrees, to the full
extent permitted by law, that, in case of an Event of Default, neither Trustor
nor anyone claiming through or under Trustor will set up, claim or seek to take
advantage of any moratorium, reinstatement, forbearance, appraisement,
valuation, stay, extension, homestead, exemption or redemption laws now or
hereafter in force in order to prevent or hinder the enforcement or foreclosure
of this Deed of Trust or the absolute sale of the Mortgaged Property, the
delivery of possession thereof immediately after such sale to the purchaser at
such sale, or the

                                         -19-

<PAGE>

exercise of any other remedy hereunder; and Trustor, for itself and all who may
at any time claim through or under it, hereby waives to the full extent that it
may lawfully so do, the benefit of all such laws, and any and all right to have
assets subject to the security interest of this Deed of Trust marshalled upon
any foreclosure or sale under the power herein granted or a sale in inverse
order of alienation.

    7.7  DISCONTINUANCE OF PROCEEDINGS.  In case Beneficiary shall have
proceeded to enforce any right, power or remedy under this Deed of Trust by
foreclosure, entry or otherwise, or in the event Beneficiary commences
advertising of the intended exercise of the sale under power provided hereunder
and such proceeding or advertisement shall have been withdrawn, discontinued or
abandoned for any reason, or shall have been determined adversely to
Beneficiary, then in every such case (i) the parties hereto shall be restored to
their former positions and rights, (ii) all rights, powers and remedies of
Beneficiary shall continue as if no such proceeding had been taken, (iii) each
and every Event of Default declared or occurring prior or subsequent to such
withdrawal, discontinuance or abandonment shall be and shall be deemed to be a
continuing Event of Default and (iv) neither this Deed of Trust, nor the Notes,
nor the Indebtedness, nor any other Security Document, shall be or shall be
deemed to have been reinstated or otherwise affected by such withdrawal,
discontinuance or abandonment; and Trustor hereby expressly waives the benefit
of any statute or rule of law now provided, or which may hereafter be provided,
which would produce a result contrary to or in conflict with the above.

    7.8  APPLICATION OF RENTS AND PROCEEDS.  The proceeds of any sale of the
Mortgaged Property, and the Rents and all other sums received by Beneficiary
under the Security Documents, shall be applied by Beneficiary (or the receiver,
if one is appointed) to the extent that funds are so available therefrom to the
following in the order of priority that Beneficiary, in its sole discretion, may
determine:

      (a)     To the payment of the costs and expenses of taking possession of
    the Mortgaged Property and of holding, using, leasing, repairing, improving
    and selling the same, including, without limitation, (i) receivers' fees,
    (ii) court costs, (iii) attorneys' and accountants' fees, (iv) costs of
    advertisement, (v) trustee's fees, and (vi) the payment of any and all
    Impositions, liens, security interests or other rights, titles or interests
    equal or superior to this Deed of Trust (except those to which the
    Mortgaged Property has been sold subject to and without in any way implying
    Beneficiary's prior consent to the creation thereof);

      (b)     To the payment of all amounts, other than the Principal Balance
    and accrued but unpaid interest, which may be due under the Security
    Documents, together with interest thereon as provided therein;

      (c)     To the payment of all accrued but unpaid interest due on the
    Notes;

      (d)     To the payment of the Principal Balance and any remaining portion
    of the Indebtedness;

      (e)     To the extent funds are available therefor, and to the extent
    known by Beneficiary, and required by law, to the payment of any
    indebtedness or obligation secured by a subordinate interest in the
    Mortgaged Property; and

      (f)     Any remaining funds to Trustor.

                                         -20-

<PAGE>

              TRUSTOR SHALL BE LIABLE FOR ANY DEFICIENCIES IN THE EVENT THE
PROCEEDS ARE NOT SUFFICIENT TO COVER ITEMS (a) THROUGH (e) ABOVE.

    7.9  LEASES.  Beneficiary, at its option, is authorized to foreclose this
Deed of Trust subject to the rights of any lessees of the Mortgaged Property
under any Leases, and the failure to make any such lessees parties to any such
foreclosure proceedings and to foreclose their rights will not be, nor be
asserted to be by Trustor, a defense to any proceedings instituted by
Beneficiary to collect the Indebtedness.

    7.10 PURCHASE BY BENEFICIARY.  Upon any foreclosure sale or sales of all or
any portion of the Mortgaged Property under the power herein granted or pursuant
to judicial proceedings, Beneficiary may bid for and purchase the Mortgaged
Property and shall be entitled to apply all or any part of the Indebtedness as a
credit to the purchase price and, in such case, this Deed of Trust, the Note and
documents evidencing expenditures secured hereby shall be presented to the
person conducting the sale in order that the amount of said indebtedness so used
or applied may be credited thereon as having been paid.

    7.11 POWER TO FILE NOTICES AND CURE DEFAULTS.  Trustor hereby irrevocably
appoints Beneficiary and its successors and assigns, as its attorney-in-fact,
which agency is coupled with an interest, (a) to execute and/or record any
notices of completion, cessation of labor, or any other notices that Beneficiary
deems appropriate to protect Beneficiary's interest, (b) upon the issuance of a
deed pursuant to the foreclosure of this Deed of Trust or the delivery of a deed
in lieu of foreclosure, to execute all instruments of assignment or further
assurance with respect to the Leases and Rents in favor of the grantee of any
such deed, as may be necessary or desirable for such purpose, (c) to prepare,
execute and file or record financing statements, continuation statements,
applications for registration and like papers necessary to create, perfect or
preserve Beneficiary's security interests and rights in or to any of the
"Collateral" (as defined herein), and (d) upon the occurrence of an event, act
or omission which, with notice or passage of time or both, would constitute an
Event of Default, to perform any obligation of Trustor hereunder; provided,
however, that:  (i) Beneficiary as such attorney-in-fact shall only be
accountable for such funds as are actually received by Beneficiary; and (ii)
Beneficiary shall not be liable to Trustor or any other person or entity for any
failure to act under this section.

    7.12 SUITS TO PROTECT THE MORTGAGED PROPERTY.  Beneficiary shall have the
power to institute and maintain such suits and proceedings as it may deem
necessary or appropriate (i) to prevent any impairment of the Mortgaged Property
by any acts which may be unlawful or constitute an Event of Default under this
Deed of Trust, (ii) to preserve or protect its interest in the Mortgaged
Property and in the Leases and Rents arising therefrom, and (iii) to restrain
the enforcement of or compliance with any legislation or other governmental
enactment, rule or order that may be unconstitutional or otherwise invalid, if
the enforcement of or compliance with such enactment, rule or order would impair
the security hereunder or be prejudicial to the interest of Beneficiary.

    7.13 PROOFS OF CLAIM.  In the case of any receivership, insolvency,
bankruptcy, reorganization, arrangement, adjustment, composition or other
proceedings affecting Trustor, its creditors or its property, Beneficiary, to
the extent permitted by law, shall be entitled to file such proofs of claim and
other documents as may be necessary or advisable in order to have the claims of
Beneficiary allowed in such proceedings for the entire

                                         -21-

<PAGE>

amount of the Indebtedness at the date of the institution of such proceedings
and for any additional amount of the Indebtedness after such date.

    7.14 NO CURE OR WAIVER.  Neither (a) the entry upon or taking possession of
all or any part of the Mortgaged Property, (b) any collection of rents, issues,
profits, insurance proceeds, condemnation awards, other security or proceeds of
other security, or other sums, (c) the application of any collected sum to the
Indebtedness or any Obligation, nor (d) the exercise of any other right or
remedy (including without limitation, the assignment of Rents) by Beneficiary,
Trustee or any receiver shall cure or waive any breach, Event of Default or
notice of default under this Deed of Trust or limit or impair the Indebtedness,
the Obligations or Trustor's liability therefor; nullify the effect of any
notice of default or notice of sale (unless all Indebtedness Obligations then
due have been paid and performed and Trustor has cured all other Events of
Default); impair the status of the security; prejudice Beneficiary or Trustee in
the exercise of any right or remedy; or be construed as an affirmation by
Beneficiary of any tenancy, lease or option or a subordination of the lien of
this Deed of Trust.

                                      Article 8

                                     CONDEMNATION

    8.1  GENERAL.  Immediately upon its obtaining knowledge of the institution
or the threatened institution of any proceeding for the condemnation of the
Mortgaged Property, or any part thereof, Trustor shall notify Trustee and
Beneficiary of such fact.  Trustor shall then, if requested by Beneficiary, file
or defend its claim thereunder and prosecute same with due diligence to its
final disposition and shall cause any awards or settlements to Trustor or any
related party to be paid over to Beneficiary for disposition pursuant to the
terms of this Deed of Trust.  Trustor may be the nominal party in such
proceeding, but Beneficiary shall be entitled to participate in and to control
the same and to be represented therein by counsel of its own choice; and Trustor
will deliver, or cause to be delivered, to Beneficiary such instruments as may
be reasonably requested by it from time to time to permit such participation. 
If the Mortgaged Property is taken or diminished in value, or if a consent
settlement is entered, by or under threat of such proceeding, the award or
settlement payable to Trustor by virtue of its interest in the Mortgaged
Property shall be, and by these presents is, assigned, transferred and set over
unto Beneficiary to be held by it in trust, subject to the lien and security
interest of this Deed of Trust, and disbursed as follows:  

         (a)  If (i) all of the Mortgaged Property is taken, (ii) so much of
the Mortgaged Property is taken, or the Mortgaged Property is so diminished in
value, that the remainder thereof cannot (in Beneficiary's judgment) continue to
be operated profitably for the purpose for which it was being used immediately
prior to such taking or diminution, (iii) an Event of Default shall have
occurred, or (iv) the Mortgaged Property is partially taken or diminished in
value and (in Beneficiary's judgment) need not be rebuilt, restored or repaired
in any manner, then, in any such event, the entirety of the sums so paid to
Beneficiary shall be applied by it in the order recited in Paragraph 8.2
hereinbelow; or

         (b)  If (i) only a portion of the Mortgaged Property is taken and the
portion remaining can (in Beneficiary's judgment), with rebuilding, restoration
or repair, be profitably operated for the purpose referred to in Paragraph
8.1(a)(ii) hereinabove, (ii) none of the other facts recited in Paragraph 8.1(a)
hereinabove exists, (iii) Trustor shall deliver to

                                         -22-

<PAGE>

Beneficiary plans and specifications for such rebuilding, restoration or repair
acceptable to Beneficiary, which acceptance shall be evidenced by Beneficiary's
written consent thereto, and (iv) Trustor shall thereafter commence the
rebuilding, restoration or repair and complete same, all in substantial
accordance with the plans and specifications and within a time period acceptable
to Beneficiary, and shall otherwise comply with Paragraph 4.8 hereinabove, then
such sums shall be paid to Trustor to reimburse Trustor for money spent in the
rebuilding, restoration or repair; otherwise, same shall be applied by
Beneficiary in the order recited in Paragraph 8.2 hereinbelow.

    8.2  APPLICATION OF PROCEEDS.  All proceeds received by  Beneficiary with
respect to a taking or a diminution in value of the Mortgaged Property by
condemnation shall be applied:

         (a)  to reimburse Trustee and Beneficiary for all costs and expenses,
including attorneys' fees, incurred in connection with collection of the said
proceeds;

         (b)  to the payment of those items recited in Paragraph 7.8(b) through
(f) hereinabove; provided, however, that if such proceeds are required under
Paragraph 8.1(b) hereinabove to be applied to the rebuilding, restoration or
repair of the Mortgaged Property, the provisions of Paragraphs 4.7 and 4.8
hereinabove shall determine the conditions precedent for utilizing such proceeds
for such purpose.


                                      Article 9

                                  SECURITY AGREEMENT

    9.1  SECURITY INTEREST.  This Deed of Trust (a) shall be construed as a
deed to secure debt on the Mortgaged Property, and (b) shall also constitute and
serve as a "Security Agreement" on personal property within the meaning of, and
shall constitute until this Deed of Trust shall terminate as provided in Article

Code as enacted in the State of Colorado with respect to the Personalty,
Fixtures, Major Agreements and Leases and Rents.  To this end, Trustor has
GRANTED, BARGAINED, CONVEYED, ASSIGNED, TRANSFERRED and SET OVER, and by these

Beneficiary a first and prior security interest and all of Trustor's right,
title and interest in, to, under and with respect to the Personalty, Fixtures,
Major Agreements, and Leases and Rents ("Collateral"), subject to the Permitted
Encumbrances, to secure the full and timely payment of the Indebtedness and the
full and timely performance and discharge of the Obligations.  It is the intent

Agreements, Leases and Rents, that all items contained in the definition of
"Major Agreements", "Leases" and "Rents" which are included within Article 9 of
the applicable Uniform Commercial Code be covered by the security interest
granted in this Article 9 and that all items contained in the definition of
"Major Agreements", "Leases" and "Rents" which are excluded from Article 9 of
the applicable Uniform Commercial Code be covered by the provisions of Article 2

    9.2  FINANCING STATEMENTS.  Trustor hereby agrees with Beneficiary to
execute and deliver to Beneficiary, in form and substance satisfactory to
Beneficiary, such Financing Statements and such further assurances as
Beneficiary may, from time to time, reasonably consider necessary to create,
perfect and preserve Beneficiary's security interest herein granted, and
Beneficiary may cause such statements and assurances to be

                                         -23-

<PAGE>

recorded and filed, at such times and places as may be required or permitted by
law, to so create, perfect and preserve such security interest.

    Notwithstanding any of the provisions hereof, Beneficiary shall not be
deemed to have accepted any property other than cash in satisfaction of any
obligation of Trustor to Beneficiary unless Beneficiary shall make an express
written election of such remedy under C.R.S. Section 4-9-505, or other
applicable law.

    9.3  UNIFORM COMMERCIAL CODE REMEDIES.  Beneficiary shall have all the
rights, remedies and recourses with respect to the Personalty, Fixtures, Major

applicable law.

                                         -24-

<PAGE>

    9.7  NO OBLIGATION OF BENEFICIARY.  The assignment and security interest
herein granted shall not be deemed or construed to constitute Beneficiary as a
trustee in possession of the Mortgaged Property, to obligate Beneficiary to
lease the Mortgaged Property or attempt to do same, or to take any action, incur
any expense or perform or discharge any obligation, duty or liability whatsoever
under any of the Major Agreements, Leases or otherwise.

    9.8  HOLD HARMLESS.  Beneficiary shall not be obligated to perform or
discharge, nor does it hereby undertake to perform or discharge, any obligation,
duty or liability under the Major Agreements or the Leases or under or by reason
of this Deed of Trust, and Trustor shall and does hereby agree to indemnify
Beneficiary for and to hold Beneficiary harmless from any and all liability,
loss or damage which it may or might incur under any of the Major Agreements or
the Leases or under or by reason of this Deed of Trust and from any and all
claims and demands whatsoever which may be asserted against it by reason of any
alleged obligations or undertakings on its part to perform or discharge any of
the terms, covenants or agreements contained in any of the Major Agreements or
Leases.  Should Beneficiary incur any such liability, loss or damage under any
of the Major Agreements or Leases or under or by reason of this Deed of Trust or
in the defense of any such claims or demands, the amount thereof, including all
costs, expenses and attorneys' fees, shall be secured hereby, and Trustor shall
reimburse Beneficiary therefor promptly upon demand.


                                      Article 10

                   ASSIGNMENT OF MAJOR AGREEMENTS, LEASES AND RENTS

    10.1 ASSIGNMENT.  For ten dollars ($10.00) and other good and valuable
consideration, including the indebtedness evidenced by the Note, the receipt and
sufficiency of which are hereby acknowledged, Trustor has GRANTED, BARGAINED,
SOLD and CONVEYED, and by these presents does GRANT, BARGAIN, SELL and CONVEY
absolutely unto Beneficiary the Major Agreements, the Leases and the Rents
subject only to the Permitted Encumbrances applicable thereto and the
hereinafter referenced License.  TO HAVE AND TO HOLD the Major Agreements, the
Leases and the Rents unto Beneficiary, forever, and Trustor does hereby bind
itself, its successors and assigns to warrant and forever defend the title to
the Major Agreements, the Leases and the Rents, subject only to the Permitted
Encumbrances applicable thereto, unto Beneficiary against every person
whomsoever lawfully claiming or to claim the same or any part thereof; provided,
however, should the Indebtedness be paid according to the tenor and effect
thereof as and when same shall become due and payable and should the Obligations
be performed and discharged on or before the date same are to be performed and
discharged, then this assignment shall terminate and be of no further force and
effect, and all rights, titles and interests conveyed pursuant to this
assignment shall become revested in Trustor without the necessity of any further
act or requirement by Trustor or Beneficiary.

    10.2 LIMITED LICENSE.  Beneficiary hereby grants to Trustor a limited
license (the "License"), nonexclusive with the rights of Beneficiary reserved in
Paragraph 10.4 hereof, to exercise and enjoy all incidences of ownership of the
Major Agreements, the Leases and the Rents, including specifically but without
limitation the right to collect (but not more than one month in advance),
demand, sue for, attach, levy, recover and receive the Rents, and to give proper
receipts, releases and acquittances therefor.

                                         -25-

<PAGE>

    10.3 ENFORCEMENT OF MAJOR AGREEMENTS AND LEASES.  So long as the License is
in effect, Trustor shall (a) submit any and all proposed Major Agreements and
Leases to Beneficiary for approval prior to the execution thereof, (b) duly and
punctually perform and comply with any and all representations, warranties,
covenants and agreements expressed as binding upon Trustor under any Major
Agreement or Lease, (c) maintain each of the Major Agreements and Leases in full
force and effect during the term thereof, (d) appear in and defend any action or
proceeding in any manner connected with any of the Major Agreements and Leases,
(e) deliver to Beneficiary execution counterparts of all Major Agreements and
Leases, (f) act in a commercially reasonable manner in entering into, performing
and enforcing the Major Agreements and the Lease, and (g) deliver to Beneficiary
such further information, and execute and deliver to Beneficiary such further
assurances and assignments, with respect to the Major Agreements and Leases as
Beneficiary may from time to time reasonably request.  Without Beneficiary's
prior written consent, Trustor shall not (h) do or knowingly permit to be done
anything to materially impair the value of any of the Leases, (i) except for
deposits not to exceed one month's rent for any one lessee, collect any of the
Rent more than one (1) month in advance of the time when the same becomes due,
(j) discount any future accruing Rent, (k) amend or modify any of the financial
or other economic terms of any Major Agreement or Lease, (l) terminate any Major
Agreement or Lease other than as a result of a material default thereunder, or
(m) assign or grant a security interest in or to the License or any of the Major
Agreements or Leases.  

    10.4 SUITS; ATTORNMENT.  Notwithstanding the License, Beneficiary hereby
reserves, and upon the occurrence and during the continuance of an Event of
Default may exercise, the right and Trustor hereby acknowledges that Beneficiary
has the right (but not the obligation) to collect, demand, sue for, attach,
levy, recover and receive any Rent, to give proper receipts, releases and
acquittances therefor and, after deducting the expenses of collection, to apply
the net proceeds thereof as a credit upon any portion of the Indebtedness
selected by Beneficiary, notwithstanding that such portion selected may not then
be due and payable or that such portion is otherwise adequately secured. 
Trustor hereby authorizes and directs any lessee of the Mortgaged Property to
deliver any such payment to, and otherwise to attorn all other obligations under
the Leases direct to Beneficiary.  Trustor hereby ratifies and confirms all that
Beneficiary shall do or cause to be done by virtue of this Article 10.  No
lessee shall be required to inquire into the authority of Beneficiary to collect
any Rent, and any lessee's obligation to Trustor shall be absolutely discharged
to the extent of its payment to Beneficiary.

    10.5 REMEDIES.  Upon or at any time after the occurrence of any Event of
Default, Beneficiary, at its option and in addition to the remedies provided in
Article 7 hereof, shall have the complete, continuing and absolute right, power
and authority to terminate the License solely by the giving of written notice of
termination to Trustor.  Upon Beneficiary's giving of such notice, the License
shall immediately terminate without any further action being required of
Beneficiary.  Thereafter, Beneficiary shall have the exclusive right, power and
authority to take any and all action as described in Paragraph 10.4 hereof,
regardless of whether a foreclosure sale of the remainder of the Mortgaged
Property has occurred under this Deed of Trust, or whether Beneficiary has taken
possession of the remainder of the Mortgaged Property or attempted to do any of
the same.  No action referred to in Paragraph 10.4 or this Paragraph 10.5 taken
by Beneficiary shall constitute an election of remedy.

                                         -26-

<PAGE>

    10.6  NO OBLIGATION OF BENEFICIARY.  Neither the acceptance by Beneficiary
of the assignment granted in this Article 10, nor the granting of any other
right, power, privilege or authority in this Article 10 or elsewhere in this
Deed of Trust, nor the exercise of any of the aforesaid, shall (a) prior to the
actual taking of physical possession and operation control of the Mortgaged
Property by Beneficiary, be deemed to constitute Beneficiary as a "mortgagee in
possession" or (b) at any time thereafter, obligate Beneficiary (i) to appear in
or defend any action or proceeding relating to the Major Agreements, the Leases,
the Rents or the remainder of the Mortgaged Property, (ii) to take any action
hereunder, (iii) to expend any money or incur any expenses or perform or
discharge any obligation, duty or liability with respect to any Major Agreement
or Lease, (iv) to assume any obligation or responsibility for any deposits which
are not physically delivered to Beneficiary or (v) for any injury or damage to
person or property sustained in or about the Mortgaged Property.

    10.7  NO MERGER OF ESTATES.  Except as permitted by Paragraph 10.2, so long
as any part of the Indebtedness and the Obligations secured hereby remain unpaid
and undischarged, the fee and leasehold estates to the Mortgaged Property shall
not merge but rather shall remain separate and distinct, notwithstanding the
union of such estates either in Trustor, Beneficiary, any lessee or any third
party by purchase or otherwise.

    10.8  TRUSTOR'S INDEMNITIES.  Trustor shall indemnify and hold Beneficiary
and Trustee harmless from and against any and all liability, loss, cost, damage
or expense which Beneficiary or Trustee may incur under or by reason of this
assignment, or for any action authorized hereby which is taken by Beneficiary or
Trustee pursuant to and in accordance with the provisions hereof, or by reason
of or in defense of any and all claims and demands whatsoever which may be
asserted against Beneficiary or Trustee arising out of the Major Agreements and
the Leases.  In the event Beneficiary or Trustee incurs any such liability,
loss, cost, damage or expense, the amount thereof together with all attorneys'
fees and interest thereon at the Default Rate specified in the Loan Agreement
shall be payable by Trustor to Beneficiary or Trustee immediately, without
demand, and shall be secured under Article 2 hereof.

    10.9  CONFLICT.  It is the intent of the parties that no conflict exist
between the absolute assignment contained in this Article 10 and the collateral
conveyance contained in Article 2 hereof.  However, if and to the extent any
such conflict be perceived to exist as to the Major Agreements, the Leases or
the Rents, such conflict shall be resolved in favor of the absolute assignment
contained in this Article 10.


                                      Article 11

                                    MISCELLANEOUS

    11.1 PERFORMANCE AT TRUSTOR'S EXPENSE.  Trustor shall (a) reimburse
Beneficiary, promptly upon demand, for all amounts expended, advanced or
incurred by Beneficiary to satisfy any obligation of Trustor under the Security
Documents, which amounts shall include all court costs, attorneys' fees
(including, without limitation, for trial, appeal or other proceedings), fees of
auditors and accountants and other investigation expenses reasonably incurred by
Beneficiary in connection with any such matters; and (b) pay any and all other
costs and expenses of performing or complying with any and all of the
Obligations.  For all purposes of this Deed of Trust, Beneficiary's costs and

                                         -27-

<PAGE>

expenses shall include, without limitation, fees for trial, appeal or other
proceedings), accounting fees, environmental consultant fees (if any), auditor
fees, and the cost to Beneficiary of any documentary taxes, recording fees,
brokerage fees, title insurance premiums and title surveys.  In addition,
Trustor recognizes and agrees that formal written appraisals of the Mortgaged
Property by a licensed independent appraiser may be required by Beneficiary's
internal procedures and/or federal regulatory reporting requirements on an
annual and/or specialized basis.  Except to the extent that certain of these
costs and expenses are included within the definition of Indebtedness, the
payment by Trustor of any of these costs and expenses shall not be credited, in
any way or to any extent, against any portion of the Indebtedness.  

    11.2 SURVIVAL OF OBLIGATIONS.  Each and all of the Obligations shall
survive the execution and delivery of the Security Documents, and the
consummation of the loan called for therein, and shall continue in full force
and effect until the Indebtedness shall have been paid in full; provided,
however, that nothing contained in this Paragraph 11.2 shall limit the
obligations of Trustor as set forth in Paragraphs 3.3, 4.12, 9.8 and 10.8
herein.

    No merger shall occur as a result of Beneficiary's acquiring any other
estate in, or any other lien on, the Mortgaged Property unless Beneficiary
consents to a merger in writing.  Furthermore, the assignment of the Rents and
other liens, security interests, rights and remedies granted hereunder to
Beneficiary, and the covenants, representations, warranties and obligations of
Trustor which are not satisfied or discharged by any foreclosure of the
Mortgaged Property, shall survive such foreclosure and remain in force and
effect thereafter, it being acknowledged and agreed that all obligations of
Trustor and rights and remedies of Beneficiary set forth herein are contractual
in nature, and such obligations, rights and remedies, and all liens,
assignments, security interests and other security provided to Beneficiary
hereunder and under the other Security Documents (but excluding the lien against
the Mortgaged Property or portions thereof that are foreclosed), shall not be
extinguished by the subject foreclosure.

    11.4 RECORDING AND FILING.  Trustor will cause the Security Documents and
all amendments and supplements thereto and substitutions therefor to be

the right to change its address for notice hereunder to any other location
within the continental United States by the giving of notice to the other party

    11.6 NO WAIVER.  Any failure by Trustee or Beneficiary to insist, or any
election by Trustee or Beneficiary not to insist, upon strict performance by
Trustor of any of the terms, provisions or conditions of the Security Documents
shall not be deemed to be a waiver of same or of any other term, provision or
condition thereof, and Trustee and Beneficiary shall have the right at any time
or times thereafter to insist upon strict performance by Trustor of any and all
such terms, provisions and conditions.  No delay or omission by Trustee or
Beneficiary, or by any holder of any of the Notes, to exercise any right, power
or remedy accruing upon any breach or Event of Default shall exhaust or impair
any such right, power or remedy or shall be construed to be a waiver of any such
breach or Event of Default, or acquiescence therein, and every right, power and
remedy given by this Deed of Trust to Trustee or Beneficiary may be exercised
from time to time and as often as may be deemed expedient by Trustee or
Beneficiary.  No consent or waiver, expressed or implied, by Trustee or
Beneficiary to or of any breach or Event of Default by Trustor in the
performance of the Obligations of Trustor hereunder or to any other Event of

other breach or Event of Default in the performance of the same or any other
Obligations of Trustor hereunder.  Failure on the part of Trustee or Beneficiary
to complain of any act or failure to act or to declare an Event of Default,
irrespective of how long such failure continues, shall not constitute a waiver
by Trustee or Beneficiary of its rights hereunder or impair any rights, powers,
or remedies of Trustee or Beneficiary hereunder.

    No act or omission by Trustee or Beneficiary shall release, discharge,
modify, change or otherwise affect the original liability under the Notes, this
Deed of Trust or any other Obligations of Trustor or any subsequent purchaser of
the Mortgaged Property or any part thereof, or any maker, cosigner, endorser,
surety or guarantor, or preclude Trustee or Beneficiary from exercising any
right, power or privilege herein granted or intended to be granted in the event
of any Event of Default then made or by any subsequent Event of Default, or
alter the security title, security interest or lien of this Deed of Trust,
except as expressly provided in an instrument or instruments executed by Trustee
and Beneficiary.  Without limiting the generality of the foregoing, Trustee and
Beneficiary may: (i) grant forbearance or an extension of time for the payment
of all or any portion of the Indebtedness; (ii) take other or additional
security for the payment of the Indebtedness; (iii) waive or fail to exercise
any right granted hereunder or in the Notes; (iv) change any of the terms,
covenants, conditions or agreements of the Notes or this Deed of Trust;
(v) consent to the filing of any map, plat or replat affecting the Mortgaged
Property; (vi) consent to the granting of any easement or other right affecting
the Mortgaged Property; (vii) make or consent to any agreement subordinating the
security title, security interest or lien hereof; or (viii) take or omit to take
any action whatsoever with respect to the Notes, this Deed of Trust, the
Mortgaged Property or any document or instrument evidencing, securing or in any
way relating to the Indebtedness; all without releasing, discharging, modifying,
changing or affecting any such liability, or precluding Trustee or Beneficiary
from exercising any such right, power or privilege, or affecting the security
title, security interest or lien of this Deed of Trust.  In the event of the
sale or transfer by operation of law or otherwise of all or any part of the
Mortgaged Property, Trustee and Beneficiary, without notice, are hereby
authorized and empowered to deal with any such vendee or transferee with
reference to the Mortgaged Property or the Indebtedness, or with reference to
any of the terms, covenants, conditions or agreements hereof, as fully and to
the

                                         -29-

<PAGE>

same extent as it might deal with the original parties hereto and without in any
way releasing and/or discharging any liabilities, Obligations or undertakings.

    11.7 BENEFICIARY'S RIGHT TO PERFORM THE OBLIGATIONS.  If Trustor shall
fail, refuse or neglect to make any payment or perform any act required by the
Security Documents within the applicable notice and cure period, if any, then at
any time thereafter, and without notice to or demand upon Trustor and without
waiving or releasing any other right, remedy or recourse Beneficiary may have
because of same, Beneficiary may (but shall not be obligated to) make such
payment or perform such act for the account of and at the expense of Trustor,
and shall have the right to enter the Land and Improvements for such purpose and
to take all such action thereon and with respect to the Mortgaged Property as it
may reasonably deem necessary or appropriate.  If Beneficiary shall elect to pay
any Imposition or other sums due with reference to the Mortgaged Property,
Beneficiary may do so in reliance on any bill, statement or assessment procured
from the appropriate Governmental Authority or other issuer thereof without
inquiring into the accuracy or validity thereof.  Similarly, in making any
payments to protect the security intended to be created by the Security
Documents, Beneficiary shall not be bound to inquire into the validity of any
apparent or threatened adverse title, lien, encumbrance, claim or charge before
making an advance for the purpose of preventing or removing the same.  Trustor
shall indemnify Beneficiary for all losses, expenses, damages, claims and causes
of action, including reasonable attorneys' fees, incurred or accruing by reason
of any acts performed by Beneficiary pursuant to the provisions of this
Paragraph 11.7 or by reason of any other provision in the Security Documents. 
All sums paid by Beneficiary pursuant to this Paragraph 11.7, and all other sums
expended by Beneficiary to which it shall be entitled to be indemnified,
together with interest thereon at the Default Rate provided in the Loan
Agreement from the date of such payment or expenditure until paid, shall
constitute additions to the Indebtedness, shall be secured by the liens,
security interests and rights created by the Security Documents and shall be
paid upon demand.  Beneficiary shall provide Trustor reasonable notice of any
action taken by Beneficiary under this Paragraph 11.7.

    11.8 COVENANTS RUNNING WITH THE LAND.  All Obligations contained in this
Deed of Trust are intended to be, and shall be construed as, covenants running
with the Mortgaged Property.

    11.9 SUCCESSORS AND ASSIGNS.  All of the terms of the Security Documents
shall apply to, be binding upon and inure to the benefit of the parties thereto,
their successors, assigns, heirs and legal representatives, and all other
persons claiming by, through or under them.

    11.10 SEVERABILITY.  The Security Documents are intended to be performed in
accordance with, and only to the extent permitted by, all applicable Legal
Requirements.  If any provision of any of the Security Documents or the
application thereof to any person or circumstance shall, for any reason and to
any extent, be invalid or unenforceable, then neither the remainder of the
instrument in which such provision is contained nor the application of such
provision to other persons or circumstances nor the other instruments referred
to hereinabove shall be affected thereby, but rather, shall be enforced to the
greatest extent permitted by law.

    11.11 ENTIRE AGREEMENT AND MODIFICATION.  The Security Documents contain
the entire agreements between the parties relating to the subject matter hereof
and thereof, and all prior agreements relative thereto which are not contained
herein or therein are terminated.  The Security Documents may not be amended,
revised, waived, discharged, released or terminated

                                         -30-

<PAGE>


orally, but only by a written instrument or instruments executed by the party
against which enforcement of the amendment, revision, waiver, discharge, release
or termination is asserted.  Any alleged amendment, revision, waiver, discharge,
release or termination which is not so documented shall not be effective as to
any party.

    11.12 ASSIGNMENT.  This Deed of Trust is assignable by Beneficiary and any
such assignment hereof by Beneficiary shall operate to vest in the assignee all
rights and powers herein conferred upon and granted to Beneficiary.

    11.13 TIME IS OF THE ESSENCE.  Time is of the essence with respect to each
and every covenant, agreement and obligation of Trustor under this Deed of
Trust, the Notes and any and all other Security Documents.

    11.14 COUNTERPARTS.  This Deed of Trust may be executed in any number of
counterparts, each of which shall be an original, but all of which together
shall constitute but one instrument.

    11.15 APPLICABLE LAW.  This Deed of Trust shall be governed by and
construed according to the laws of the State of Colorado from time to time in
effect, except that the laws of the State of Georgia and applicable United
States Federal law shall determine whether or not the transaction evidenced by
the Security Documents is usurious.  It is expressly stipulated and agreed to be
the intent of the parties to comply at all times with applicable Georgia law
governing the maximum rate or amount of interest payable on the Indebtedness (or
applicable United States Federal law to the extent that it permits Beneficiary
to contract for, charge, take, reserve or receive a greater amount of interest
than under Georgia law).  If the applicable law is ever revised, repealed or
judicially interpreted so as to render usurious any amount called for under the
Loan Agreement, the Notes or under any of the other Security Documents, or
contracted for, charged, taken, reserved or received with respect to the
Indebtedness, or if Beneficiary's exercise of the option to accelerate the
maturity of the Notes, or if any prepayment results in the payment of interest
in excess of that permitted by applicable law, then it is the parties' express
intent that all excess amounts theretofore collected by Beneficiary be credited
to the principal balance of the Notes or any other principal indebtedness of
Trustor (or, if the Notes and all other indebtedness have been or would thereby
be paid in full, refunded to Trustor), and the provisions of the Loan Agreement,
the Note, this Deed of Trust and the other Security Documents immediately be
deemed reformed and the amounts thereafter collectible hereunder and thereunder
reduced, without the necessity of the execution of any new documents, so as to
comply with the then applicable law, but so as to permit the recovery of the
fullest amount otherwise called for hereunder and thereunder.  All sums paid or
agreed to be paid for the use, forbearance or detention of the Indebtedness
shall, to the extent permitted by applicable law, be amortized, prorated,
allocated and spread throughout the full term of the Indebtedness until payment
in full so that the rate or amount of interest on account of the Indebtedness
does not exceed the usury ceiling from time to time in effect and applicable to
the Indebtedness for so long as the Indebtedness is outstanding.

    11.16 SUBROGATION.  If any or all of the proceeds of the Notes have been
used to extinguish, extend or renew any indebtedness heretofore existing against
the Mortgaged Property, then, to the extent of such funds so used, the
Indebtedness and this Deed of Trust shall be subrogated to all of the rights,
claims, liens, titles and interests heretofore existing against the Mortgaged
Property to secure the indebtedness so extinguished, extended or renewed, and
the former rights, claims, liens, titles and interests, if any, are not waived,
but rather,

                                         -31-

<PAGE>

are continued in full force and effect in favor of Beneficiary and are merged
with the lien and security interest created herein as cumulative security for
the repayment of the Indebtedness and the satisfaction of the Obligations.

    11.17 HEADINGS.  The Article, Paragraph and Subparagraph entitlements
hereof are inserted for convenience of reference only and shall in no way alter,
modify or define, or be used in construing, the text of such Articles,
Paragraphs or Subparagraphs.

    11.18 NO JOINT VENTURE.  Notwithstanding anything in any of the Security
Documents or in any other agreement or commitment to the contrary, neither the
Security Documents nor the transactions described in the Security Documents nor
the rights and obligations granted therein shall in any way create or contribute
to the creation of a partnership or joint venture or similar arrangement between
Trustor and Beneficiary.

    11.19  JURY TRIAL WAIVER AND CONSENT TO JURISDICTION AND VENUE.  EACH PARTY
TO THIS DEED OF TRUST HEREBY WAIVES ANY RIGHT SUCH PARTY MAY HAVE UNDER ANY
APPLICABLE LAW TO A TRIAL BY JURY WITH RESPECT TO ANY SUIT OR LEGAL ACTION WHICH
MAY BE COMMENCED BY OR AGAINST SUCH PERSON OR THE OTHER PARTIES CONCERNING THE
INTERPRETATION, CONSTRUCTION, VALIDITY, ENFORCEMENT OR PERFORMANCE OF THIS DEED
OF TRUST OR ANY OF THE OTHER SECURITY DOCUMENTS.  EACH PARTY TO THIS DEED OF
TRUST FURTHER AGREES AND CONSENTS TO THE JURISDICTION OF ANY FEDERAL COURT
SITTING IN ATLANTA, GEORGIA WITH RESPECT TO ANY SUCH SUIT OR LEGAL ACTION, AND
EACH PARTY TO THIS DEED OF TRUST FURTHER AGREES AND CONSENTS TO VENUE OF ANY
FEDERAL COURT SITTING IN FULTON COUNTY, GEORGIA WITH REGARD TO ANY SUCH SUIT OR
LEGAL ACTION.

    11.20  ACCEPTANCE OF TRUST; POWERS AND DUTIES OF TRUSTEE.  Trustee accepts
this trust when this Deed of Trust is recorded.  Except as may be required by
applicable law, Beneficiary may from time to time apply to any court of
competent jurisdiction for aid and direction in the execution of the trust
hereunder and the enforcement of rights and remedies available hereunder, and
may obtain orders or decrees directing, confirming or approving acts in the
execution of said trust and the enforcement of said remedies.

    11.21 LOAN AGREEMENT.  Reference is hereby made for all purposes to the
Loan Agreement, which is hereby incorporated by reference herein.  In the event
of a conflict between the terms and provisions hereof and the Loan Agreement,
the Loan Agreement shall govern.


    IN WITNESS WHEREOF, Trustor has executed this Deed of Trust under seal, as
of the day and year first above written.

such Prime Rate is discontinued as a standard, a comparable

reference rate designated by Holder as a substitute therefor.  The principal
hereof and interest thereon shall be payable at the principal office of the
Holder (or at such other place as the Holder may reasonably designate) in such
coin or currency of the United States of America that at the time of payment
shall be legal tender for the payment of public or private debts in funds
collectible on the date which is prescribed herein for payment.

     In the event that payment is not made on the date prescribed for payment
herein, simple interest shall accrue on the aggregate amount due and payable
(including principal, interest or both, as the case may be) but remaining
unpaid, at the rate of eighteen percent (18%) per annum, (but in no event higher
than the maximum rate of interest permissible under applicable provisions of
law) from the date such amount becomes due and payable until the date of
payment.  In the event that the Holder is required to engage the services of an
attorney or to institute litigation to effect collection of the sums due
pursuant to this Note, the Company shall pay all reasonable costs of such
collection, including, without limitation reasonable attorneys' fees and court
costs not to exceed 15% of the outstanding principal and amount of, and the
accrued and unpaid interest on, the Note after default.

     The indebtedness evidenced hereby is secured by that certain Loan and
Security Agreement dated March 28, 1996, by and between Company and Holder (the
"Loan Agreement").

     2.   AUTHORIZED ISSUE.   This Note is one of the Convertible Secured Notes
limited in the aggregate amount to One Million Five Hundred Thousand Dollars
($1,500,000) and referenced to in the Loan Agreement.  In addition to its rights
and remedies as set forth herein, the Holder shall have all of the rights and
remedies of the Lender under the Loan Agreement.

     3.   EVENTS OF DEFAULT.  Upon the occurrence of an "Event of Default" as
such term is defined in the Loan Agreement, then, and in any such event and
without limiting its remedies as provided in the Loan Agreement, the Holder may,
upon delivery of a notice of any such Event of Default given to the Company,
declare the remaining unpaid and unconverted sums due under this Note to be
forthwith due and payable, whereupon the aggregate then unpaid and unconverted
principal amount of this Note, together with all accrued interest thereon, shall
become immediately due and payable without presentment, demand, protest or other
notice of any kind, all of which are hereby expressly waived.

     4.   CONVERSION.    At any time on or before the Maturity Date, the
outstanding principal amount of, and the accrued and unpaid interest on, this
Note shall be convertible into common stock, $0.01 par value, of Company (the
"Common Stock") at the


                                       -2-

<PAGE>

option of the Holder in accordance with the following provisions of this Section
4.

          4.1  OPTIONAL CONVERSIONS.  Subject to and upon compliance with the
     other provisions of this Note and the provisions of this Section 4, the
     Holder shall have the right at the Holder's option to convert all or any
     portion of the outstanding principal of, and the accrued interest on, this
     Note into fully paid and nonassessable shares of Common Stock, at the
     Conversion Price (hereafter defined) in effect on the Conversion Date
     (hereafter defined), upon the terms hereinafter set forth.

          4.2  CONVERSION PRICE.   The outstanding principal amount of, and
     accrued interest on, this Note shall be convertible into the number of
     shares of Common Stock as is determined by multiplying the amount to be
     converted times a fraction, the numerator of which is $1.00 and the
     denominator of which is the Conversion Price in effect on the Conversion
     Date.  The Conversion Price at which shares of Common Stock shall be 
     issuable upon conversion of this Note shall be Seventy Cents ($0.70) 
     (subject to adjustment as provided below, hereafter the "Conversion
     Price").  The Conversion Price shall be subject to adjustment as set forth
     in Section 4.5 below.

          4.3  MECHANICS OF CONVERSION. The Holder may exercise the conversion
     right specified in Section 4.1 above by written notice stating that the
     Holder elects to convert all or a specified portion of the outstanding
     principal amount of and interest on this Note.  Conversion shall be deemed
     to have been effected on the date when both notice of an election to
     convert and the original of this Note are delivered; any such date is
     referred to herein as the "Conversion Date".  As promptly as practicable
     thereafter Company shall issue and deliver to the Holder a certificate or
     certificates for the number of full shares of Common Stock to which the
     Holder is entitled rounded up to the next whole share as provided in
     Section 4.4 below in consideration of the delivery of the Note to the
     Company at such time.  If this Note is to be converted in part only,
     Company shall issue and deliver to the Holder contemporaneously therewith
     the original of this Note with an appropriate notation of the reduction in
     the principal amount so converted or a replacement note identical in all
     respects to this Note except as adjusted to reflect the outstanding
     principal amount thereof after giving effect to such conversion.  The
     person in whose name the certificate or certificates of Common Stock is to
     be issued shall be deemed to have become a holder of record of such Common
     Stock on the applicable Conversion Date.  Conversion of all


                                       -3-

<PAGE>

     or any portion of the principal of this Note shall not affect Company's
     obligation to pay interest accrued through the date of conversion on the
     outstanding principal balance of this Note which is converted and on any
     remaining outstanding principal balance hereof.

          4.4  FRACTIONAL SHARES.  No fractional shares of Common Stock or scrip
     shall be issued upon conversion of this Note.  Instead of any fractional
     shares of Common Stock which would otherwise be issuable upon conversion of
     this Note, the number of full shares of Common Stock issuable upon
     conversion hereof shall be increased to the next highest number of whole
     shares.

          4.5  CONVERSION PRICE ADJUSTMENTS. The Conversion Price and the number
     of shares of Common Stock issuable upon conversion (the "Conversion
     Shares") shall be subject to adjustment from time to time as follows:

               (a)  STOCK DIVIDENDS.  If the number of shares of Common Stock
          outstanding at any time after March 28, 1996 is increased by stock
          dividend payable in shares of Common Stock or by a subdivision or 
          split-up of shares of Common Stock, then immediately after the
          record date fixed for the determination of holders of Common Stock
          entitled to receive such stock dividend or the effective date of such
          subdivision or split-up, as the case may be, the Conversion Price
          shall be appropriately reduced and the number of Conversion Shares
          proportionately increased so that the Holder thereafter shall be
          entitled to receive the number of shares of Common Stock of Company
          which the Holder would have owned immediately following such action
          had this Note been then outstanding and converted immediately prior
          thereto.

               (b)  COMBINATION OF STOCK.  If the number of shares of Common
          Stock outstanding at any time after March 28, 1996 is decreased by a
          combination of the outstanding shares of Common Stock, then,
          immediately after the effective date of such combination, the
          Conversion Price shall be appropriately increased and the number of
          Conversion Shares proportionately decreased so that the Holder shall
          be entitled to receive the number of shares of Common Stock which the
          Holder would have owned immediately following such action had this
          Note been then outstanding and converted immediately prior thereto.

               (c)  REORGANIZATION. In case of any capital reorganization of
          Company, or of any reclassification



                                       -4-

<PAGE>

          of the Common Stock, or in case of the consolidation of Company with
          or the merger of Company with or into any other corporation,
          partnership or other business entity in which Company is not the
          survivor, or any share exchange involving the Common Stock or of the
          sale, lease or other transfer of all or substantially all of the
          assets of Company to any other corporation, partnership or other
          business entity, or in the case of any distribution of cash (other
          than dividends not exceeding, in the aggregate, net income earned from
          December 31, 1995 to the date on which such dividend is declared) or
          other assets or of notes or other indebtedness of Company or any other
          securities of Company (except Common Stock) to the holders of Common
          Stock, this Note shall, after such capital reorganization,
          reclassification, consolidation, merger, share exchange, sale, lease
          or other transfer or such distribution, be convertible into the number
          of shares of stock or other securities or property to which a holder
          of the Common Stock issuable (at the time of such capital
          reorganization, reclassification, consolidation, merger, share
          exchange, sale, lease or other transfer or such distribution)
          upon conversion of this Note as the Holder would have been entitled 
          to receive upon such capital reorganization reclassification, 
          consolidation, merger, share exchange, sale, lease or other transfer
          or such distribution in place of (or in addition to, in the case of 
          any such event after which Common Stock remains outstanding) the 
          shares of Common Stock into which this Note would otherwise have been
          convertible; and in any such case, if necessary, the provisions set 
          forth herein with respect to the rights and interests thereafter of 
          the Holder shall be appropriately adjusted so as to be applicable, 
          as nearly as may reasonably be, to any share of stock or other 
          securities or property thereafter deliverable on the conversion of 
          this Note.  The subdivision or combination of shares of Common Stock 
          issuable upon conversion of this Note into a greater or lesser number
          of shares of Common Stock (whether with or without par value) shall 
          not be deemed to be a reclassification of the Common Stock for the 
          purposes of this subparagraph (c).

               (d)  ROUNDING OF CALCULATIONS.  All calculations under this
          Section 4.5 shall be made to the nearest cent or to the nearest one
          hundredth (1/100th) of a share, as the case may be.


                                       -5-

               (e)  TIMING OF ISSUANCE OF ADDITIONAL COMMON STOCK UPON CERTAIN
          ADJUSTMENTS.  In any case in which the provisions of this Section 4.5
          require that an adjustment shall become effective immediately after a
          record date for an event, Company may defer until the occurrence of
          such event issuing to the Holder hereof the additional shares of
          Common Stock or other property issuable or deliverable upon exercise
          by reason of the adjustment required by such event over and above the
          shares of Common Stock or other property issuable or deliverable upon
          such conversion before giving effect to such adjustment; PROVIDED,
          HOWEVER, that Company upon request shall deliver to the Holder a due
          bill or other appropriate instrument evidencing the Holder's right to
          receive such additional shares or other property, and such cash, upon
          the occurrence of the event requiring such adjustments.


          4.6  STATEMENT REGARDING ADJUSTMENTS.  Whenever the Conversion Price
     shall be adjusted as provided in Section 4.5, Company shall forthwith file,
     at the principal office of Company, a statement showing in detail the facts
     requiring such adjustment and the Conversion Price that shall be in effect
     after such adjustment, and Company shall also cause a copy of such
     statement to be sent by mail, first class postage prepaid, to the Holder at
     its address appearing on Company's records.  Each such statement shall be
     signed by Company's chief financial officer.  Where appropriate, such copy
     may be given in advance and may be included as part of a notice required to
     be mailed under the provisions of Section 4.7 below.

          4.7  NOTICE TO HOLDER.  In the event Company proposes to take any
     action of the type described in clause (a), (b) or (c) of paragraph 4.5
     above, Company shall give notice to Holder in the manner set forth in
     Section 4.6 above, which notice shall specify the record date, if any, with
     respect to any such action and the approximate date on which such action is
     to take place.  Such notice shall also set forth such facts with respect
     thereto as shall be reasonably necessary to indicate the effect of such
     action (to the extent such effect may be known at the date of such notice)
     on the Conversion Price and the number, kind or class of shares or other
     securities or property which shall be deliverable or purchasable upon the
     occurrence of such action or deliverable upon conversion of this Note.  In
     the case of any action which would require the fixing of a record date,
     such notice shall be given at least 10 days prior to the date so fixed, and
     in case of all other action, such notice shall be given at least 15 days
     prior to the taking of such proposed action.


                                       -6-

          4.8  COSTS.  Company shall pay all documentary, stamp, transfer or
     other transactional taxes attributable to the issuance or delivery of
     shares of Common Stock or other securities or property upon conversion of
     this Note; PROVIDED, HOWEVER, that Company shall not be required to pay any
     income taxes incurred by the holder of this Note or any taxes which may be
     payable in respect of any transfer involved in the issuance or delivery of
     any certificate for such shares or securities in any name other than that
     of Holder.

          4.9  RESERVATION OF SHARES.  Company shall reserve at all times so
     long as this Note remains outstanding, free from preemptive rights, out of
     its treasury stock or its authorized but unissued shares of Common Stock,
     or both, solely for the purpose of effecting the conversion of this Note,
     sufficient shares of Common Stock to provide for the conversion of this
     Note and set aside and keep available any other property deliverable upon
     conversion of this Note.

          4.10  APPROVALS.  If any shares of Common Stock or other securities
     to be reserved for the purpose of conversion of this Note requires 
     registration with or approval of any governmental authority under any 
     Federal or state law before such shares or other securities may be validly
     issued or delivered upon conversion, then Company will in good faith and
     as expeditiously as possible endeavor to secure such registration or
     approval, as the case may be.

          4.11 VALID ISSUANCE.  All shares of Common Stock or other 
     securities which may be issued upon conversion of this Note will upon 
     issuance by Company be duly and validly issued, fully paid and 
     nonassessable and free from all taxes, liens and charges with respect to 
     the issuance thereof and Company shall take no action which will cause a 
     contrary result.

     5.  PUT AND CALL.

     5.1  PUT.  (a)  Immediately upon the occurrence of any "Put Event" (as such
term is defined below), Holder may at its option at any time upon giving written

at such time to be due and payable in accordance herewith.  The Company shall
have thirty (30) business days after receipt of the foregoing notice from Holder
in which to tender the full amount of the Remaining Indebtedness to Holder in
full and complete satisfaction hereof;

                     stock with the power to control the management of
                     the Company, by any "person" or "group" as such
                     terms are used for purposes of Section 13(d)
                     and 14(d) of the Securities Act of 1934 (the
                     "Exchange Act"), or by any person or group that is
                     or becomes a "beneficial owner" as such term is

           Year of Redemption        Redemption Price
           ------------------        ----------------
