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





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




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




company  payment of the  redemption  price of the shares of Series  1325 E. 16th
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




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




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
any shares of any class or to receive any other rights;

          c) there shall occur any capital  reorganization  of the  corporation,
reclassification  of the shares of the corporation  (other than a subdivision or
combination of its  outstanding  common stock),  consolidation  or merger of the

                                        7




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,
a notice  stating (i) the date which (x) has been set as the record date for the
purpose of such dividend, distribution, or rights, or (y) such reclassification,
reorganization,  consolidation, merger, conveyance, dissolution, liquidation or,
winding  up is to take  place and (ii) the  record  date as of which  holders of
common stock of record shall be entitled to other property deliverable upon such
reclassification,    reorganization,    consolidation,    merger,    conveyance,
dissolution, liquidation or winding up.

               (vii)  Notices.  Any notice  required by the  provisions  of this
paragraph  (e) of this  Article  Second to be given to the  holders of shares of
Series  1325 E. 16th  Ave.  Preferred  Stock  shall be in  writing  and shall be
delivered  by  personal  service  or  agent,  by  telegraph  or cable or sent by
registered or certified  mail,  return receipt  requested,  with postage thereon
fully  prepaid.  All such  communications  shall be  addressed to each holder of
record at its  address  appearing  on the books of the  corporation.  If sent by
telegraph or cable, a conformed copy of such  telegraphic or cabled notice shall
promptly be sent by mail (in the manner provided above) to the holders.  Service
of any such communication made only by mail shall be deemed complete on the date
of actual delivery as shown by the addressee's registry or certification receipt
or at the  expiration  of the  fourth  business  day after the date of  mailing,
whichever is earlier in time.

               (viii)  Fractional  Shares.  No fractional shares of common stock
shall be issued upon conversion of Series 1325 E. 16th Ave.  Preferred Stock. ln
lieu of any fractional  shares to which the holder would  otherwise be entitled,
the corporation shall pay cash equal to the product of such fraction  multiplied
by the Market Price of one share of the  corporation's  common stock on the date
of conversion.

               (ix) Payment of Taxes.  The corporation will pay all taxes (other
than taxes based upon income) and other governmental charges that may be imposed
with respect to the issue or delivery of shares of common stock upon  conversion
of shares of the Series 1325 E. 16th Ave.  Preferred  Stock,  including  without
limitation  any tax or other  charge  imposed in  connection  with any  transfer
involved  in the issue and  delivery  of shares of common  stock in a name other
