Item 2.  ACQUISITION OR DISPOSITION OF ASSETS.

     On April 17, 1997, Commercial Acquisitions Corporation ("Company") acquired
a commercial building located at 1325 East 16th Avenue,  Denver,  Colorado 80218
("Building")  as an  investment  property.  The  Building,  built in the 1960's,
contains  approximately  8,000 square feet on nearly 18,000 square feet of land.
The Building was acquired from its primary tenant, Dr. Richard W. Metcalfe, DDS,
who has  conducted  his dental  practice in the Building for over 25 years.  Dr.
Metcalfe will continue to remain a tenant in the Building under a ten year lease
with the  Company  ("Lease"),  which  Lease was  signed by Dr.  Metcalfe  in his
corporate and personal capacities. Prior to the acquisition, Dr. Metcalfe had no
material  relationship with the Company,  any director or officer of the Company
or any associate of any such director or officer.

     The Company will receive  $4,500 per month in rent from Dr.  Metcalfe under
the Lease,  with annual  increases  in rent in years 6 through 10 based upon the
Metro Denver  Consumer Price Index.  Dr.  Metcalfe is responsible for all taxes,
insurance, maintenance and utilities of the Building under the Lease.

     The Company  acquired the Building for  $465,000.00,  which was funded by a
first  mortgage from  Colorado  Community  First  National Bank in the amount of
$335,000  ("Mortgage")  and by the issuance of preferred stock in the Company in
the amount of $144,650. The Mortgage accrues interest at a fixed rate of 8.875%,
amortized  over 20 years with a 5 year call  provision.  The  Company's  monthly
Mortgage payments are $2,987.00.

     The preferred  stock issued to acquire the Building is comprised of 144,650
shares  of  $0.0001  par value  Series  1325  East  16th  Avenue 9%  Convertible
Cumulative Preferred Stock ("Series 1325 Preferred Stock"),  representing all of
the authorized  shares of Series 1325 Preferred Stock. The Series 1325 Preferred
Stock was issued at $1.00 per share.  The holders of the Series  1325  Preferred
Stock have no voting  rights and are not  entitled  to  preemptive  rights  with
respect to the Series 1325 Preferred Stock. Dr. Metcalfe purchased 80,000 shares
of  the  Series  1325  Preferred  Stock  as  part  of the  Building  acquisition
transaction.

     Each  share of the  Series  1325  Preferred  Stock is  entitled  to receive
quarterly  dividends  at 9% per annum on the  "rental  income"  received  by the
Company  from the  Building.  "Rental  income"  received  from the  Building  is
determined from the net cash received as rental  payments on the Building,  less
any expenses relating to the Building. These dividends are cumulative.

     On or after  April 17,  1999,  the board of  directors  of the  Company may
redeem the Series  1325  Preferred  Stock at $1.00 per share,  plus  accrued and
unpaid  cumulative  dividends.  Between April 17, 1999 and April 17, 2002,  each
share of the Series 1325 Preferred  Stock is  convertible,  at the option of the
holder and  subject to any prior  redemption  by the board of  directors  of the
Company,  into one share of common  stock at a price equal to 80% of the average
market price of the common stock (as  determined  by the  Company's  articles of

                                      - 2 -


<PAGE>

incorporation,  as  amended)  for  the 30  days  prior  to the  conversion.  The
conversion  price will be adjusted for various  events,  including stock splits,
combinations, certain dividends and distributions, reclassification, exchange or
substitution, reorganization, merger, consolidation or sales of assets.

     In the event of a liquidation  or  dissolution  of the Company,  the Series
1325 Preferred Stock is entitled to  preferential  payment over the common stock
in an amount  equal to $1.00 per share,  plus any accrued and unpaid  cumulative
dividends. The common stockholders are entitled to all remaining funds, if any.

Item 7.  FINANCIAL STATEMENTS AND EXHIBITS.

         (a)      Financial statements of the Company:

                           Item  7(a)(3)  requires  financial  statements  to be
                  filed for real estate properties acquired as specified by Rule
                  3-14  of  Regulation  S-X.  The  Company  believes   financial
                  statements are not required because: the Building was acquired
                  from  an  entity  controlled  by  the  primary  tenant  of the
                  Building and,  therefore,  there is no history of prior rental
                  revenues;  the  Company  has a ten year  Lease  with this same
                  tenant,  which  will be the only  rental  income to be derived
                  from the Building;  and the Lease is "triple-net"  whereby the
                  tenant will pay all operating expenses of the Building.

         (b)      Pro forma financial information.

                           Item 7(b)(1) requires pro forma financial information
                  to be filed when required under Article 11 of Regulation  S-X.
                  As stated above,  financial statements of the Building are not
                  being filed. Therefore, pro forma financial information is not
                  required for this transaction.  Annual revenue of the Building
                  will be $54,000,  annual interest  expense will be $30,000 and
                  annual  depreciation  based on a 30 year life will be $16,000.
                  There  are no  other  revenues  and  expenses  expected  to be
                  incurred by the Company  directly  related to the  Building in
                  the forthcoming year. The Company will also be required to pay
                  quarterly  dividends  related  to  preferred  stock  issued to
                  acquire the Building of up to $0.0225 per share or $13,000 per
                  year to the extent  rental income is received on the Building,
                  and an imputed dividend of approximately $15,000 per year (for
                  two years)  will also be  recorded  as a result of a favorable
                  conversion factor to the preferred stock.

         (c)      Exhibits.

                  (3.1)    Articles   of    Amendment   to   the   Articles   of
                           Incorporation of Commercial Acquisitions Corporation,
                           filed with the  Colorado  Secretary of State on April
                           16, 1997.

                              ARTICLES OF AMENDMENT
                                     TO THE
                            ARTICLES OF INCORPORATION
                                       OF
                       COMMERCIAL ACQUISITIONS CORPORATION

     Pursuant to the provisions of the Colorado  Business  Corporation  Act, the
undersigned  corporation  adopts the  following  Articles  of  Amendment  to its
Articles of Incorporation:

     FIRST: The name of the corporation is Commercial Acquisitions Corporation.

     SECOND: The following amendments to the Articles of Incorporation were duly
adopted by the board of directors on April 10, 1997, in accordance  with Section
7-106-102 of the Colorado Business Corporation Act.

     Article Second of the Articles of Incorporation is hereby amended by adding
the following provisions:

     137,500 shares of the corporation's preferred stock shall consist of Series
1325 East 16th Avenue 9% Convertible  Cumulative  Preferred  Stock  (hereinafter
referred  to as  "Series  1325 E.  16th  Ave.  Preferred  Stock").  The  rights,
preferences,  privileges and  restrictions  imposed upon the Series 1325 E. 16th
Ave. Preferred Stock are as follows:

          (a)  Dividends;  Right to  Dividends.  The  Series  1325 E.  16th Ave.
Preferred Stock is entitled to receive, out of funds legally available therefor,
dividends at the  quarterly  rate of up to $0.0225 per share and no more, to the
extent  that  Rental  Income,  as defined  below,  is  actually  received by the
corporation  on the  corporation's  property  located at 1325 East 16th  Avenue,
Denver,  Colorado  80218 (the  "Property").  Rental Income is defined as the net
cash received as rental payments on the Property,  less any expenses relating to
the Property. Such dividend shall be paid in cash on or before the 90th day (the
"Dividend Payment Date") after the last day of the quarter with respect to which
such dividend  shall be payable,  which quarters shall begin on May 1, August 1,
November 1 and February 1 of each year (a "Dividend Period"),  commencing May 1,
1997.  If any  dividends  payable  on any  share of  Series  1325 E.  16th  Ave.
Preferred  Stock  shall not be paid for any  reason,  the right of the holder of
such share of Series  1325 E. 16th Ave.  Preferred  Stock to receive  payment of
such dividend shall not lapse or terminate,  but each such unpaid  dividend (the
"Unpaid  Dividends") shall accumulate and shall be paid without interest to such
holder to the extent that the Rental Income for those past  Dividend  Periods is
received by the  corporation  and on the Dividend  Payment Date for the Dividend
Period when such past due Rental Income is actually received by the corporation.
In the event that only a portion of the Rental Income due to the  corporation is
received by the corporation on the Property during any Dividend Period,  holders
of shares of Series  1325 E. 16th Ave.  Preferred  Stock  shall be  entitled  to
receive their pro rata share of dividends  based upon the Rental Income actually


<PAGE>


received by the corporation  during that Dividend Period.  In the event that the
Property  is sold,  transferred,  assigned or  conveyed  (a  "Transfer")  by the
corporation,  the holders of shares of Series 1325 E. 16th Ave.  Preferred Stock
shall not be entitled to any further  dividends  after the effective date of the
Transfer. The corporation's determination of Rental Income on the Property shall
be  audited  on an  annual  basis at the  corporation's  expense  as part of the
corporation's  fiscal  year  end  audit  by  an  independent   certified  public
accountant to determine that the  corporation's  determination  of Rental Income
has been calculated in accordance with generally accepted accounting principals.
All such dividends shall accrue from the date of issuance  whether or not earned
so that no dividends  or other  distributions  shall be made by the  corporation
with  respect to the common  stock,  and no common  stock shall be  purchased or
redeemed by the corporation, unless and until all Unpaid Dividends on the Series
1325 E. 16th Ave. Preferred Stock for all past Dividend Periods and for the then
current  Dividend  Period  shall  have been  declared  and paid or set aside for
payment.  After all Unpaid  Dividends on the Series 1325 E. 16th Ave.  Preferred
Stock for all past  Dividend  Periods and for the then current  Dividend  Period
shall  have been  declared  and paid or set aside for  payment,  if the board of
directors shall declare dividends out of funds legally available therefor,  such
additional dividends may be declared on the common stock.

          (b)  Liquidation  and  Dissolution.  Upon the voluntary or involuntary
liquidation,  winding up or  dissolution of the  corporation,  out of the assets
available  for  distribution  to  shareholders  whether such assets are capital,
surplus or  earnings,  each share of Series  1325 E. 16th Ave.  Preferred  Stock
shall be entitled to receive,  in  preference to any payment on the common stock
only, an amount equal to $1.00 per share, plus cumulative  dividends as provided
in paragraph (a) of this Article  Second  accrued and unpaid to the date payment
is made  available to the Series 1325 E. 16th Ave.  Preferred  Stock.  After the
full  preferential  liquidation  amount has been paid to, or determined  and set
apart for, Series 1325 E. 16th Ave.  Preferred Stock, the remaining assets shall
be payable to the  holders of the common  stock.  In the event the assets of the
corporation are  insufficient to pay the full  preferential  liquidation  amount
required to be paid to the Series 1325 E. 16th Ave.  Preferred Stock, the Series
1325 E. 16th Ave.  Preferred  Stock shall receive such funds pro rata on a share
for share basis until the full liquidating preference on the Series 1325 E. 16th
Ave.  Preferred  Stock is paid in full,  and the balance,  if any, shall then be
paid to the holders of common stock.

     A reorganization shall not be considered to be a liquidation, winding up or
dissolution  within the meaning of this paragraph (b) of this Article Second and
the Series  1325 E. 16th Ave.  Preferred  Stock  shall be  entitled  only to the
rights provided in the plan of reorganization.

          (c) Voting.  Holders of shares of Series  1325 E. 16th Ave.  Preferred
Stock shall not be entitled to voting rights on any matter other than upon those
matters set forth in Section 7-110-104 of the Colorado Business Corporation Act.

          (d) Optional  Redemption of Series 1325 E. 16th Ave.  Preferred Stock.
On or after  April 17,  1999,  the Series 1325 E. 16th Ave.  Preferred  Stock is
subject to redemption out of funds legally available  therefor in whole, or from

                                        2

<PAGE>


time  to  time  in  part,  at  the  option  of the  board  of  directors  of the
corporation.  If only a part of the shares of Series 1325 E. 16th Ave. Preferred
Stock is to be redeemed, the redemption shall be carried out pro rata subject to
adjustment to avoid redemption of fractional  shares. The redemption price shall
be $1.00 per share of Series 1325 E. 16th Ave.  Preferred  Stock plus cumulative
dividends as provided in paragraph (a) of this Article Second accrued and unpaid
to the date fixed for redemption.

               (i)   Redemption   Notice  and  Rights  After   Redemption.   The
corporation shall mail a notice of redemption to each holder of record of shares
of Series  1325 E. 16th Ave.  Preferred  Stock to be redeemed  addressed  to the
holder at the address of such holder  appearing on the books of the  corporation
or given by the holder to the  corporation  for the purpose of notice,  or if no
such address  appears or is given,  at the place where the  principal  executive
office of the corporation is located, not earlier than 60 nor later than 20 days
before the date fixed for redemption. The notice of redemption shall include (i)
the shares of Series 1325 E. 16th Ave. Preferred Stock to be redeemed,  (ii) the
date fixed for redemption,  (iii) the redemption  price, (iv) the place at which
the  shareholders  may obtain payment of the redemption  price upon surrender of
their share certificates,  and (v) the last date prior to the date of redemption
that the right of conversion may be exercised, which is the close of business on
the day prior to the date fixed for  redemption.  If funds are  available on the
date fixed for the redemption,  then whether or not the share  certificates  are
surrendered for payment of the redemption  price,  the shares shall no longer be
outstanding  and the  holders  thereof  shall  cease to be  shareholders  of the
corporation  with  respect to the shares of Series  1325 E. 16th Ave.  Preferred
Stock  redeemed on an after the date fixed for  redemption and shall be entitled
only to receive the  redemption  price without  interest  upon  surrender of the
share  certificate.  If less than all the  shares  of  Series  1325 E. 16th Ave.
Preferred Stock  represented by one share  certificate  are to be redeemed,  the
corporation shall issue a new share certificate for the shares of Series 1325 E.
16th Ave. Preferred Stock not redeemed.

               (ii) Redemption Trust Fund. If, on or prior to any date fixed for
redemption,  the corporation deposits with any bank or trust company in Colorado
as a trust fund a sum  sufficient  to redeem,  on the date fixed for  redemption
thereof,  the  shares of Series  1325 E. 16th Ave.  Preferred  Stock  called for
redemption,  with  irrevocable  instructions  and authority to the bank or trust
company to  publish  the  notice of  redemption  thereof  (or to  complete  such
publication  if  theretofore  commenced) and to pay, on and after the date fixed
for  redemption or prior thereto,  the redemption  price of the shares of Series
1325 E. 16th Ave. Preferred Stock to their respective holders upon the surrender
of their  share  certificates,  then  from  and  after  the date of the  deposit
(although  prior to the date fixed for  redemption) the shares of Series 1325 E.
16th Ave.  Preferred  Stock so called shall be redeemed  and  dividends on those
shares  shall cease to accrue after the date fixed for  redemption.  The deposit
shall  constitute  full  payment  of the  shares  of  Series  1325 E.  16th Ave.
Preferred  Stock to their holders and from and after the date of the deposit the
shares  of  Series  1325 E.  16th  Ave.  Preferred  Stock  shall  no  longer  be
outstanding and the holders thereof shall cease to be shareholders  with respect
to such  shares of Series  1325 E. 16th Ave.  Preferred  Stock and shall have no
rights with respect  thereto  except the right to receive from the bank or trust


                                        3

<PAGE>

Ave.  Preferred  Stock without  interest,  upon surrender of their  certificates
therefor and the right to convert the shares in accordance with paragraph (e) of
this Article  Second.  After 2 years,  the bank or trust company shall return to
the  corporation  funds deposited and not claimed and thereafter the holder of a
share  certificate  for  shares of Series  1325 E.  16th  Ave.  Preferred  Stock
redeemed shall look to the corporation for payment.

          (e)  Conversion.  The  holders of Series  1325 E. 16th Ave.  Preferred
Stock have the following conversion rights (the "Conversion Rights"):

               (i) Right to Convert and Conversion  Price.  Each share of Series
1325 E. 16th Ave.  Preferred  Stock shall be  convertible,  at the option of the
holder  thereof,  at any time commencing  April 17, 1999 and continuing  through
April 17, 2002, subject to any prior redemption by the board of directors of the
corporation of such Series 1325 E. 16th Ave.  Preferred Stock shares as provided
for in paragraph (d) of this Article  Second.  Each share of Series 1325 E. 16th
Ave. Preferred Stock shall be convertible at the office of the corporation or of
any transfer  agent for such Series 1325 E. 16th Ave.  Preferred  Stock,  as the
case may be, into one fully paid and  nonassessable  share of common  stock at a
price equal to 80% of the average "Market Price," as defined in paragraph (g) of
this Article Second, of the common stock for the 30 days prior to the conversion
("Conversion  Price"), as determined on the day before a notice of conversion is
provided to the corporation.

               (ii)  Mechanics  of  Conversion.  Before  any holder of shares of
Series 1325 E. 16th Ave.  Preferred  Stock shall be entitled to convert the same
into full shares of common stock  pursuant to  paragraph  (e)(i) of this Article
Second,  the holder shall surrender the  certificate or  certificates  therefor,
duly  endorsed,  at the office of the  corporation  or of any transfer agent for
such Series  1325 E. 16th Ave.  Preferred  Stock,  as the case may be, and shall
give written notice to the  corporation at such office that the holder elects to
convert the same and shall state  therein the holder's name or the name or names
of the  holder's  nominees  in  which  the  holder  wishes  the  certificate  or
certificates for shares of common stock to be issued.  The corporation shall, as
soon as practicable thereafter, issue and deliver at such office to such holder,
or to the holder's  nominee or nominees,  a certificate or certificates  for the
number of full shares of common  stock to which the holder  shall be entitled as
aforesaid.  A  conversion  pursuant to paragraph  (e)(i) of this Article  Second
shall be deemed to have occurred  immediately  prior to the close of business on
the date of such  surrender of the shares of Series 1325 E. 16th Ave.  Preferred
Stock to be converted,  and the person or persons entitled to receive the shares
of common stock issuable upon such conversion  shall be treated for all purposes
as the record  holder or holders  of such  shares of common  stock on such date.
Each holder of the Series 1325 E. 16th Ave.  Preferred  Stock who  converts  any
shares of the Series 1325 E. 16th Ave. Preferred Stock shall be entitled to, and
the corporation shall promptly pay in cash, or set aside for payment, all unpaid
dividends with respect to such converted  shares of the Series 1325 E. 16th Ave.
Preferred Stock, whether or not earned or declared, to and including the time of
conversion.  A holder  of the  Series  1325 E.  16th  Ave.  Preferred  Stock who

                                        4

<PAGE>


converts any shares of the Series 1325 E. 16th Ave. Preferred Stock shall not be
entitled to any remaining dividends with respect to the Series 1325 E. 16th Ave.
Preferred Stock so converted,  but shall be entitled to receive,  on the date of
the conversion, the arrearages, if any, with respect to any shares of the Series
1325 E. 16th Ave. Preferred Stock so converted.

               (iii) Adjustments to Conversion Price.

               (1) Special  Definition.  For purposes of this paragraph (e)(iii)
of this Article Second, the following definition shall apply:

               "Original  Issue Date" shall mean,  the original  date on which a
share of  Series  1325 E.  16th Ave.  Preferred  Stock was first  issued to each
preferred shareholder.

               (2)  Adjustment  for  Stock  Splits  and  Combinations.   If  the
corporation shall at any time or from time to time after the Original Issue Date
applicable to Series 1325 E. 16th Ave.  Preferred  Stock effect a subdivision of
the outstanding  common stock,  the applicable  Conversion  Price then in effect
immediately  before that  subdivision  shall be  proportionately  decreased and,
conversely,  if the corporation shall at any time or from time to time after the
Original  Issue Date  applicable  to Series  1325 E. 16th Ave.  Preferred  Stock
combine the outstanding shares of common stock, the applicable  Conversion Price
then in effect  immediately  before  the  combination  shall be  proportionately
increased.  Any  adjustments  under this  paragraph  (e)(iii)(2) of this Article
Second  shall  become  effective  at the  close  of  business  on the  date  the
subdivision or combination becomes effective.

               (3) Adjustment for Certain  Dividends and  Distributions.  In the
event the  corporation  at any time,  or from time to time,  after the  Original
Issue Date applicable to Series 1325 E. 16th Ave.  Preferred Stock shall make or
issue,  or fix a record date for the  determination  of holders of common  stock
entitled  to  receive,  a dividend  or other  distribution  payable in shares of
common stock,  then and in each such event the applicable  Conversion Price then
in effect shall be  decreased  as of the time of such  issuance or, in the event
such a record  date shall have been  fixed,  as of the close of business on such
record date, by multiplying the Conversion Price then in effect by a fraction:

                  a) the  numerator of which shall be the total number of shares
of common stock  issued and  outstanding  immediately  prior to the time of such
issuance or the close of business on such record date, and

                  b) the  denominator  of which  shall be the  total  number  of
shares of common stock issued and outstanding  immediately  prior to the time of
such  issuance  or the close of  business on such record date plus the number of
shares of common  stock  issuable in payment of such  dividend or  distribution;
provided,  however,  if such record date shall have been fixed and such dividend
is not fully  paid or if such  distribution  is not fully made on the date fixed
therefor,  the Conversion Price shall be recomputed  accordingly as of the close

                                        5

<PAGE>


of business on such record date and thereafter  such  Conversion  Price shall be
adjusted pursuant to this paragraph (e)(iii)(3) of this Article Second as of the
time of actual payment of such dividends or distributions.

               (4) Adjustment for Other Dividend and Distributions. In the event
the  corporation  at any time or from time to time after the Original Issue Date
of Series 1325 E. 16th Ave. Preferred Stock shall make or issue, or fix a record
date for the  determination  of holders of common stock  entitled to receive,  a
dividend or other  distribution  payable in securities of the corporation  other
than shares of common stock,  then and in such event provisions shall be made so
that the holders of Series 1325 E. 16th Ave.  Preferred Stock shall receive upon
conversion  thereof,  in  addition  to the  number of  shares  of  common  stock
receivable  thereupon,  the amount of securities of the  corporation  which they
would have  received  had their  Series 1325 E. 16th Ave.  Preferred  Stock been
converted into common stock on the date of such event and had thereafter, during
the period from the date of such event to and  including  the  conversion  date,
retained such securities (together with any distributions payable thereon during
such  period)  receivable  by them  as  aforesaid  during  such  period,  giving
application to all adjustments called for during such period under paragraph (e)
of this  Article  Second with respect to the rights of the holders of the Series
1325 E. 16th Ave. Preferred Stock.

               (5) Adjustment for  Reclassification,  Exchange, or Substitution.
If the common stock issuable upon the conversion of the Series 1325 E. 16th Ave.
Preferred  Stock at any time or from time to time after the Original  Issue Date
applicable to Series 1325 E. 16th Ave.  Preferred  Stock,  shall be changed into
the same or different number of shares of any class or classes of stock, whether
by  capital   reorganization,   reclassification  or  otherwise  (other  than  a
subdivision  or  combination  of  shares  or  stock  dividends  provided  for in
paragraphs  (e)(iii)(2)  and (3) of this Article  Second,  or a  reorganization,
merger,  consolidation,  or sale of assets provided for in paragraph (e)(iii)(6)
of this Article Second), then, and in each such event,  provisions shall be made
(by adjustment to the Conversion  Price or otherwise) so that the holder of each
share of  Series  1325 E.  16th  Ave.  Preferred  Stock  shall  have  the  right
thereafter  to convert  each share of Series 1325 E. 16th Ave.  Preferred  Stock
into the kind and amount of shares of stock and other securities receivable upon
such reorganization, reclassification, or other change, by holders of the number
of shares of common  stock into  which  such  share of Series  1325 E. 16th Ave.
Preferred   Stock  might  have  been   converted   immediately   prior  to  such
reorganization,  reclassification,  or change, all subject to further adjustment
as provided herein.

               (6) Adjustment for Reorganization, Merger, Consolidation or Sales
of Assets.  If at any time or from time to time after the Original Issue Date of
the  Series  1325  E.  16th  Ave.  Preferred  Stock  there  shall  be a  capital
reorganization  of  the  corporation  (other  than a  subdivision,  combination,
reclassification,  exchange or substitution of shares provided for in paragraphs
(e)(iii)(2) and (5) of this Article Second) or a merger or  consolidation of the
corporation  with  or  into  another   corporation,   or  the  sale  of  all  or
substantially all of the corporation's properties and assets to any other person
or entity, then, as a part of such  reorganization,  merger,  consolidation,  or
sale,  provision  shall  be made  (by  adjustment  to the  Conversion  Price  or
otherwise) so that the holders of the Series 1325 E. 16th Ave.  Preferred  Stock

                                        6

shall  thereafter  be entitled to receive upon  conversion of the Series 1325 E.
16th  Ave.  Preferred  Stock,  the  number  and kind of shares of stock or other
securities  or  property of the  corporation,  or of any  successor  corporation
resulting from such merger or consolidation or sale, to which a holder of common
stock  deliverable  upon  conversion  of such shares would have been entitled if
such capital reorganization, merger, consolidation, or sale occurred on the date
of the conversion.

               (iv) No Impairment. The corporation will not, by amendment of its
Articles of  Incorporation  or through any  reorganization,  transfer of assets,
consolidation,  merger,  dissolution,  issue or sale of  securities or any other
voluntary action, avoid or seek to avoid the observance or performance of any of
the terms to be observed or performed hereunder by the corporation,  but will at
all times in good faith assist in the carrying out of all the provisions of this
paragraph (e) of this Article Second and in the taking of all such action as may
be necessary or  appropriate,  in order to protect the conversion  rights of the
holders of the Series 1325 E. 16th Ave. Preferred Stock against impairment.

               (v)  Certificate as to  Adjustments.  Upon the occurrence of each
adjustment  or  readjustment  of the  Conversion  Price or any other  adjustment
pursuant to this paragraph (e) of this Article  Second,  the  corporation at its
expense shall promptly  compute such  adjustment or  readjustment  in accordance
with the terms  hereof and  furnish to each  holder of such  Series 1325 E. 16th
Ave. Preferred Stock a certificate setting forth such adjustment or readjustment
and showing in detail the facts upon which such  adjustment or  readjustment  is
based. The corporation shall, upon the written request at any time of any holder
of such affected Series 1325 E. 16th Ave.  Preferred Stock,  furnish or cause to
be furnished to such holder a like certificate setting forth (i) such adjustment
and readjustment, (ii) the Conversion Price at the time in effect, and (iii) the
number of shares of common stock and the amount, if any, of other property which
at the time would be received upon the conversion of a share of such Series 1325
E. 16th Ave. Preferred Stock.

               (vi) Notices of Record Date. In the event that:

          a) the  corporation  shall  set a  record  date  for  the  purpose  of
entitling  the holders of its shares of common  stock to receive a dividend,  or
other distribution, payable otherwise than in cash;

          b) the  corporation  shall  set a  record  date  for  the  purpose  of
entitling the holders of its shares of common stock to subscribe for or purchase

reclassification  of the shares of the corporation  (other than a subdivision or
combination of its  outstanding  common stock),  consolidation  or merger of the

                                        7

<PAGE>


corporation   with  or  into  another   corporation  or  conveyance  of  all  or
substantially  all of the assets of the corporation to another person or entity;
or

          d)  there  shall  occur  a  voluntary  or   involuntary   dissolution,
liquidation or winding up of the corporation;

          then, and in any such case, the  corporation  shall cause to be mailed
to the  holders of record of the  outstanding  shares of the Series 1325 E. 16th
Ave. Preferred Stock, at least 15 days prior to the date hereinafter  specified,

purpose of such dividend, distribution, or rights, or (y) such reclassification,

times reserve and keep  available,  out of its authorized but unissued shares of

deliverable  upon the  conversion  of all  shares  of  Series  1325 E. 16th Ave.
Preferred Stock from time to time  outstanding.  The corporation shall from time
to time  increase  the  authorized  number  of  shares  of  common  stock if the
remaining unissued  authorized shares of common stock shall not be sufficient to
permit the conversion of all of the Series 1325 E. 16th Ave.  Preferred Stock at
the time outstanding.

               (xi)  Retirement  of Series  1325 E. 16th  Ave.  Preferred  Stock

common  stock shall be  entitled  as of right to  subscribe  for,  purchase,  or
receive any part of any new or  additional  shares of any class,  whether now or
hereafter  authorized,   or  of  bonds,   debentures,   or  other  evidences  of
indebtedness  convertible  into or exchangeable for shares of any class, but all
such new or  additional  shares of any  class,  or bonds,  debentures,  or other
evidences of indebtedness  convertible into or exchangeable  for shares,  may be
issued  and  disposed  of by the board of  directors  on such terms and for such
consideration (to the extent permitted by law), and to such person or persons as
the board of directors in their absolute discretion may deem advisable.

         exchange designated by the board of directors,  or admitted to unlisted

         price of the common stock as reported by the Wall Street Journal on the
         day the  Market  Price  is to be  determined,  or if no such  price  is
         reported for such day,  then the  determination  of such closing  price
         shall be as of the last immediately  preceding day on which the closing
         price is so reported; or

                           (ii) If the common stock is not so listed or admitted
         to unlisted trading  privileges or so quoted, the Market Price shall be
         the  average of the last  reported  highest  bid and the  lowest  asked
         prices quoted on the National  Association of Securities Dealers,  Inc.

         Automated Quotations  System or, if not so quoted, then by the National
         Quotation Bureau, Inc.  on the day the Market Price is determined; or

     vacates  said  premises,  and all further  obligations  on the part of both
     parties hereto shall cease and Lessor shall incur no obligation  whatsoever
     from the termination of said lease.

     remain in  possession  of the  demised  premises  and  continue to pay rent

     notice (notice being expressly waived), terminate this lease an immediately
     take possession of said premises without the same working and forfeiture of

     subject and  subordinate  to the lien of any mortgages  which Lessor or its
     assigns shall make covering said premises and to any and all advances to be
     made  thereunder  and to the interest  thereon;  provided,  however,  that,
     regardless of any default under any mortgages or any  possession or sale of
     said  premises  under  such  mortgages,  so long  as  Lessee  performs  all
     covenants  and  conditions  of this  lease  and  continues  to pay  rent to
     whomsoever  may be  lawfully  entitled  to same,  this  lease and  Lessee's
     possession  thereunder  shall no be  disturbed  by the  mortgagee or anyone
     claiming under or through such mortgages.  Lessee agrees to execute any and
     all  instruments  in writing which may be required by Lessor to subordinate

     Lessor,  Lessee (and the  guarantor,  if any) shall provide the Lessor with
     the most  recent  financial  statements  as  required  by the Lessor in its
     course of business  dealing on the  property of which the demised  premises
     are a part.  The  submittal of Financial  Statements  shall be requested no
     more frequently than annually and shall be in  substantively  the same form
     as was submitted by the Lessee to the Lessor with this lease.

              Default of Tenant:

              The Lessee  further  covenants  and agrees that, if the rent above
     reserved, or any part thereof, shall be in default, or in case of breach of
     any of the  covenants or agreements  herein,  Lessor may declare this lease
     terminated,  and after the  expiration  of 10,  (Ten) days from the date of


<PAGE>

     receipt of service of written  notice to that  effect,  be  entitled to the
     possession of said  premises,  either by the expiration of this lease or by
     any  termination  of said term as herein  provided for. If the Lessee shall
     refuse to surrender and deliver up the possession of said premises,  or any
     part thereof,  and take possession thereof and repossess the same as of the
     Lessor's  former  estate,  and expel,  remove and put out of possession the
     Lessee, using such help, assistance and force in so doing as may be needful
     and proper,  without being liable for prosecution or damages therefor,  and
     without  prejudice  to any remedy  allowed by law  available in such cases.
     This paragraph shall be supplemental to paragraph 4-(b).

              Vacating During Term:

              If the Lessee shall abandon or vacate the leased  premised  before
     the end of the  term of this  lease,  or  shall  suffer  the  rent to be in
     arrears,  the  Lessor  may at its  option  and  without  notice  enter said
     premises,  remove any signs and property of the Lessee therefrom, and relet
     the  leased  premises  or any part  hereof as it may see fit  without  such
     retaking,  voiding or termination  this lease, and for the purposes of such
     reletting, the Lessor is authorized to make any repairs or changes in or to
     the leased  premises,  at the expense of the Lessee (which shall be payable
     to the Lessor  upon  demand),  as may be  necessary  or  desirable  for the
     purpose of such  reletting,  and if a sum shall not be  realized  from such
     reletting to equal the monthly rental reserved and stipulated  herein to be
     paid by the  Lessee,  the Lessee will pay such  deficiency  each month upon
     demand  therefor,  and if suit is filed to collect  any monies due from the
     Lessee under this lease,  reasonable  attorney's  fees shall be assessed as
     part of the judgments.


              Assignment and Subletting:

              Lessee  shall not  assign or  mortgage  this  lease in whole or in
     part, nor sublet all or any part of the leased  premises  without the prior
     written consent of the Lessor, and Lessor agrees that such consent will not
     be  unreasonable  withheld.  In the event the leased premises are sublet by
     the Lessee, or this lease is assigned or mortgaged,  the Lessee will remain
     solely  liable under the terms of this lease and shall not be released from
     the  performance of any of the terms,  covenants and  conditions  contained
     herein.  Provided  that there shall have been a sale of the business of the
     tenant,  (Dr.  Richard W.  Metcalfe,  DDS,  PC), such  assignment  shall be
     permitted if (a) The credit  worthiness of the new Lessee shall be equal to
     or greater than the current credit  worthiness of the existing Lessee;  or,
     (b) The current Lessee shall remain a guarantor for any and all obligations
     of the new Lessee under the terms of this Lease.  If (b) shall  apply,  the
     Lessor  agrees to review  the credit  worthiness  of the new Lessee no more
     frequently  than annually and on the annual  anniversary  date of the Lease
     and the  existing  Lessee  shall have the right to  request  release of its
     guaranty,  but the Lessor shall have no  obligation to do so in whole or in
     part until such time as the credit  worthiness  of the new Lessee  shall be
     equal to or greater  than the current  credit  worthiness  of the  existing
     Lessee.  Further,  the terms and conditions of the existing sub-lease shall
     be (a)  Disclosed  to the Lessor;  and,  (b)  Assigned by this Lease to the
     Lessor as  additional  collateral  with the  Lessors  acknowledgment  that,
     absent any default by the Lessee, any rental income derived therefrom shall
     be the property of the Lessee.  And, any sublease of any space unused as of
     this  date is  subject  to the  written  approval  of the  Lessor  and said
     approval  shall  not  be  unreasonably  withheld.  Further,  Lessor  hereby
     approves of the existing  sublease by and between the Lessee and Dr. Daniel
     W. Ray, DMD, MS and Lessee  hereby  assigns said lease to the Lessor in the
     event of any uncured  default of the Lessee  and,  with  execution  of this
     lease shall  provide the Lessor with  written  disclosure  of the terms and
     conditions of said sublease.

              Lessee agrees to deliver up and surrender to Lessor  possession of
     the leased premises,  including all plumbing,  wiring,  sewer  connections,
     lighting  fixtures,   glass,  fixtures,   walls,   ceilings,   floors,  and
     appurtenances  at the  expiration  or  termination  of  this  lease  or any
     extension  hereof,  by lapse of time or  otherwise,  in as good  order  and
     condition  as when  possession  was  taken by the  Lessee,  excepting  only
     ordinary  wear and tear or damage by the  elements  (occurring  without the
     fault of the Lessee or other  persons  permitted by the Lessee to occupy or

     remove the same and store or dispose of the said effects, without liability
     for loss or damage  thereto,  and Lessee  agrees to pay to Lessor on demand

     courts or alleyway  adjacent thereto,  if any, free from all dirt,  litter,
     debris and obstruction, including court costs, attorney's fees, storage and

     from the  Lessee to the  Lessor,  and upon the  expense  incidental  to the
     removing,  cleaning the  premises,  sell said effects,  an other  expenses,
     rendering the surplus,  if any, to the Lessee;  provided,  however,  in the
     event the process of such sale or sales are  insufficient  to reimburse the
     Lessor, Lessee shall pay such deficiency upon demand.

              Legal Costs and Expenses:

              Lessee agrees to pay Lessor for all costs and expenses,  including
     a  reasonable  attorney's  fee,  in any court  action  brought by Lessor to
     recover any rent due and unpaid under the terms  hereof,  or for the breach
     of any  of  the  terms  and  conditions  herein  contained,  or to  recover
     possession  of the leased  premises,  whether  or not such court  action or
     actions shall proceed to judgment.

              All  notices,  demands, request  or other  instruments required in
     this lease to be given by Lessee to Lessor  shall be sent by  certified  or

     expressly denied.

              Condemnation of Leased Premises:

              If the entire  demised  premises,  at any time  during the term of
     this lease or any  extension  thereof,  shall be taken by the exercise of a
     power of eminent domain,  this lease shall then terminate as of the date of
     title  vesting in such  proceeding,  all  rentals  shall be paid up to that
     date,  and Lessee  shall have no claim  against  Lessor nor the  condemning
     authority for the value of the unexpired term of this lease.

              In the event of a partial  taking of the building or more than 25%
     of the land area, which leaves the premises unfit for the normal and proper
     conduct of the business of the Lessee, then the lessee shall have the right
     to cancel and  terminate  this  lease  effective  upon the  actual  partial
     taking, all rentals shall be paid up to that date, and Lessee shall have no
     claim  against  Lessor nor the  condemning  authority  for the value of any
     unexpired term of this lease.  If this lease shall not be canceled as above
     provided,  it shall  continue in effect and the rental  after such  partial
     taking shall be that part of the rental  herein agreed to be paid which the
     value of the untaken part of the  premises,  immediately  after the taking,
     bears to the value of the entire demised  premised  immediately  before the
     taking. If the lessee's continued use of the premises requires  alterations
     and  repairs  by  reason  of a  partial  taking,  the  Lessor  may elect to
     terminate  this lease within thirty (30) days after the actual  taking;  or
     subject to Lessee's  right of  termination  above  provided,  which must be
     exercised in writing within thirty (30) days after such partial taking ,may
     elect to continue  it, in which event the Lessor  shall make all  necessary
     alterations  and repairs at its expense which are required  because of such
     partial  taking.  Until  such  alterations  and  repairs  shall  have  been
     completed,  and equitable abatement of rent shall be made to Lessee for any
     portion  of the  premises  unfit for  occupancy  and use in the  conduct of
     Lessee's  business  for the period  during which the same is unfit for such
     occupancy and use.

              In the event of any  condemnation or taking as aforesaid,  whether
     whole or  partial,  Lessee  shall not be  entitled to any part of the award
     paid for said  condemnation;  Lessor is to receive  the full amount of such
     award,  Lessee  hereby  expressly  waiving  any  right or claim to any part
     thereof. Although all such damages awarded in the event of any condemnation
     are  to  belong  to  the  Lessor,  whether  such  damages  are  awarded  as
     compensation  for  diminution  value of the  leasehold or to the fee of the
     leased premises,  Lessee shall have the right to claim and recover from the
     condemning authority,  but not from the Lessor, such compensation as may be
     separately  awarded  or  recoverable  by  Lessee in  Lessee's  own right on
     account  of any and all  damage  to  Lessee's  business  by  reason  of the
     condemnation  and for or on  account  of any cost or loss to  which  Lessee
     might  be  put  in  removing  Lessee's  merchandise,  furniture,  fixtures,
     leasehold improvements and equipment.

              Waiver:

              The  waiver  by Lessor of any  breach  of any  term,  covenant  or
     condition herein contained shall not be deemed to be a waiver of such term,
     covenant or  condition  on any  subsequent  breach of the same or any other
     term, covenant or condition herein contained.  The subsequent acceptance or
     rent  hereunder  by  Lessor  shall  not be  deemed  to be a  waiver  of any
     preceding breach by Lessee of any term covenant or condition of the time of
     the  acceptance of such rent. No covenant,  term or condition of this lease
     shall be deemed to have been waived by the Lessor, unless such waiver be in
     writing duly executed by the Lessor.


<PAGE>

              (a) Lessee shall have the option of (1) Paying the property  taxes

     satisfactory  to the  Lessor  that  said  taxes  have been paid in a timely
     manner;  or (2)  Paying  the Lessor  1/12th of the taxes  estimated  by the
     Lessor to become due in any subsequent year with each monthly payment. This
     option  must be elected on the 1st day of January of any year in writing by
     the Lessee and by notice to the Lessor.  If the Lessee shall fail to comply
     with this provision and the Lessor shall advance any sum for the payment of
     said taxation, this shall (i) Constitute a default of the Lessee; and, (ii)
     Any funds advanced by the Lessor for said  purposes,  or for any other bona
     fide obligation of the Lessee hereunder,  shall accrue interest at the rate
     of Eighteen percent, (18%), per annum with said interest due and payable by
     the Lessee.

              (b)  Lessee  shall  insure  the  property  for fire  and  extended
     coverage in the amount of Four  hundred and twenty five  thousand  dollars,
     ($425,000),  as defined herein,  i.e. form and terms of coverage,  and with
     such annual  increases in value as may be  determined by the greater of (1)
     The Metro Denver Consumer Price Index;  or, (2) An appraisal by a bona fide
     real estate broker or appraiser with the cost of such appraisal born by the
     Lessor.

              (c) Upon the expiration of the existing coverage,  which must meet
     the terms and conditions  defined herein,  i.e. form and terms of coverage,
     the Lessor may seek quotes for comparable  coverage and, if said quotes are
     comparable  as to cost and coverage and insurer,  the policy may be changed
     at the sole  discretion of the Lessee.  The costs, if any, for seeking said
     quotes  shall be (1) At the sole costs and expense of the  Lessor;  (2) The
     Lessor shall have no  obligation  to seek such quotes;  and, (3) The Lessee
     may seek such  quotes  at its sole  cost and  expense  and  submit  same in
     writing for approval by the Lessor.

              Costs of All Building Areas; Components; Grounds and Facilities

              In addition to the rental  payable  pursuant to paragraph 3 hereof
     and in any other provision of this Lease,  the Lessee shall pay any and all
     costs of operating  and  maintaining  all areas,  building  components - in
     whole or in part - grounds and facilities, including without limitation all
     parking areas,  access roads,  sidewalks,  landscaped space and other space
     used in or  available  to the  building  and  property as defined  herein..
     Operating and maintaining  such areas and facilities  shall include without
     limitation  furnishing exterior and parking area lighting,  cleaning,  snow
     removal, line painting,  care of grass, shrubs and plants, payment of water
     and sewerage  charges and general  maintenance  of all areas and facilities
     used in or available to the  building and property as defined  herein.  The
     repair  or  replacement  of any  portion  of the  building  or the  parking
     facilities  appurtenant  thereto  shall be included in such  operation  and
     maintenance.

              Additional Provisions:

              The base or  minimum  rental as  defined  herein  shall be in full
     force and effect for the first  Five,  (5),  year  period of the lease term
     plus the prorated period of 17 through 30 April, 1997. Thereafter, the base
     or minimum monthly rental shall increase on the annual  anniversary date of
     the lease, by not less than 3.50%,  (Three and 50/100's  percent) per annum
     and no  greater  than  5.50%,  (Five and  50/100's  percent),  per annum as
     determined by the Metro Denver Consumer Price Index, (CPI), as is available
     from the Bureau of Labor  Statistics or such other bona fide source of like
     information. Further, this increase shall be in full force and effect as of
     the annual  anniversary date of the Lease and the prevailing CPI, i.e. that
     which  shall  have been in effect  the  January  1st  preceding  the annual


<PAGE>

     anniversary  date of the lease.  Any subsequent or holdover period shall be
     increased by 5.5%, (Five and 50/100's percent), per annum as defined herein
     unless there shall have been other terms agreed to in writing by the Lessor
     and further,  the Lessor is not  obligated to any increase in lease term by
     this agreement.

              Successors and Assigns:

              The  obligations and rights under this lease shall be binding upon
     and  inure  to  the  benefit  of  the  heirs,  administrators,   executors,
     successors  and  assigns  of  the  parties;  provided,  however,  that  any
     assignment  or  subletting  by the Lessee in violation of the terms of this
     lease shall not vest any rights whatsoever in the assignee or subtenant.

              IN WITNESS WHEREOF, this lease is hereby executed the day and year
first above written.
