Item 2.  Acquisition or Disposition of Assets.
- ----------------------------------------------

     On January 15, 1998 (the "Effective  Date"),  Vanden Capital Group, Inc., a
Colorado  corporation  (the  "Company"),   and  Entropin,   Inc.,  a  California
corporation ("Entropin"),  completed an acquisition whereby the Company acquired
all of the outstanding  shares of Entropin  pursuant to an Agreement and Plan of
Merger  dated  December 9, 1997  between the Company and  Entropin  (the "Merger
Agreement").  Pursuant  to the  terms of the  Merger  Agreement,  the  following
actions occurred:

     (1) For and in  consideration  of the  exchange of all shares of the Common
Stock and Series A Preferred  Stock of Entropin  issued and  outstanding  on the
Effective Date:

         (a)   The Company  recapitalized  its issued and outstanding  shares of
               Common Stock ($.0001 par value) from 90,015,200 shares to 300,050
               shares by a reverse split of 1 share for 300 shares and increased
               the par value thereof to $.001 per share. The Company reduced its
               50,000,000  shares  of  Preferred  Stock  ($.0001  par  value) to
               10,000,000  shares and  increased  the par value thereof to $.001
               per share.  The Company  designated  3,210,487 of its  10,000,000
               shares of Preferred  Stock as redeemable  eight percent (8%) non-
               cumulative,  non-voting  Preferred Stock (the "Series A Preferred
               Stock).  The principal  terms of the Series A Preferred Stock are
               described  in Article III of the  Company's  Amended and Restated
               Articles of Incorporation  which is filed herewith as Exhibit 3.4
               to this Form 8-K.

         (b)   The Company  issued  5,520,000  shares of $.001 par value  Common
               Stock to shareholders  of all the issued and  outstanding  Common
               Stock of Entropin in exchange therefor on a one for one basis.

         (c)   The Company issued  3,210,487  shares of $.001 par value Series A
               Preferred Stock to shareholders of all the issued and outstanding
               Series A Preferred  Stock of  Entropin in exchange  therefor on a
               one for one basis.

     (2) Each share of the Common Stock and Series A Preferred Stock of Entropin
which was issued and  outstanding on the Effective Date, by virtue of the merger
and without any action on the part of Entropin, was retired and cancelled.

     The  Company  has  agreed to  register  the shares of Common  Stock  issued
pursuant to the Merger Agreement with the Securities and Exchange  Commission as
soon as is practicable after the Effective Date.

     Subsequent to the  acquisition,  the Company  changed its name to Entropin,
Inc. and has become engaged in the pharmaceutical  research business and will be
commercially  developing a patented  medicinal  preparation known as Esterom(R),
which is the current business of Entropin. Esterom(R) is a medicinal preparation
formulated for the treatment of impaired range of motion  associated  with acute
lower back pain and painful shoulder.  Entropin has been issued seven patents by

                                      -2-

<PAGE>

the  U.S.  Patent  Office  on  Esterom(R).  Entropin  has  a  current  and  open
Investigational New Drug File with the U.S. Food and Drug Administration and has
completed Phase II of the approval process.

     The  Merger  Agreement  and  related  transactions  were  approved  by  the
Company's  shareholders at a special meeting of the shareholders held on January
15, 1998.

     In  connection  with the Merger  Agreement,  Entropin  conducted  a private
placement of its Common  Stock  consisting  of a maximum of 30 Units,  each Unit
consisting of 10,000 shares of Common Stock, or 300,000 shares (the "Units"), at
an offering price of $27,500 per Unit, or $825,000,  on an  "all-or-none"  basis
(these shares are included in the 5,520,000 shares issued in connection with the
Merger Agreement).  The offering  terminated on December 31, 1997 and funds were
held in escrow  until the  Effective  Date.  All  offers  and sales were made by
Entropin.  The offering was made pursuant to the federal registration  exemption
contained in Section 4(2) of the Securities Act of 1933, as amended (the "Act"),
and  Rule  506 of  Regulation  D  promulgated  thereunder  only  to  "accredited
investors" as that term is defined in Rule 501(a) of Regulation D.

     The Company  currently is represented by the law firm of Brenman Bromberg &
Tenenbaum,  P.C. (the "Law Firm") and has been so represented since March, 1994.
Albert Brenman and A. Thomas Tenenbaum, shareholders of the Company and officers
and  directors  of  the  Company  until  their  resignations  subsequent  to the
Effective Date of the Merger Agreement, are officers, directors and shareholders
of the Law  Firm.  The Law Firm  will  continue  to  represent  the  Company  in
securities  law  matters.  Representation  of the Company by Brenman  Bromberg &
Tenenbaum,  P.C.  has been at the  firm's  standard  hourly  fees  for  services
involving general corporate and securities law matters.

Change in Control of the Beneficial Ownership of Company

     On the  Effective  Date,  the Company  effected a reverse  stock split of 1
share for each 300 shares of its Common Stock issued and  outstanding.  Pursuant
to the terms of the Merger  Agreement,  the Company is required to issue, and is
in the  process of  issuing,  shares of its Common  Stock and Series A Preferred
Stock to the  shareholders  of Entropin as of January 15, 1998 on the basis of 1
share of Common  Stock and Series A  Preferred  Stock for each 1 share of Common

directors or other matters as may be stated in the  resolutions  of the Board of
Directors  creating  any series of Preferred  Stock,  the holders of such series
shall have no voting power whatsoever.

          SECTION 2.1. SERIES A PREFERRED  STOCK.  All 10,000,000  shares of the
Corporation's  Preferred  Stock,  $.001 par value per share,  are  designated as

Entropin Series A Preferred Stock are set forth below.

          SECTION 2.2.  REDEMPTION/CANCELLATION  PERIOD.  The Entropin  Series A
Preferred Stock shall be issued and outstanding for a period not to exceed 2,555
days (the "Redemption/Cancellation Period"), at which time the Entropin Series A

terms and  conditions  of  Sections  2.4 and/or 2.5 below or such  shares  shall
automatically be canceled without further action by the Corporation  pursuant to

Entropin  Series A  Preferred  Stock  shall be  entitled  to  receive  an annual

          SECTION 2.4.  MANDATORY  REDEMPTION  RIGHTS. All outstanding shares of

the  Corporation  each  fiscal year  during the  Redemption/Cancellation  Period
solely pursuant to the following terms and conditions:

                                       -2-

<PAGE>



          (a) DETERMINATION OF AVAILABLE FUNDS FOR REDEMPTION. "Available Funds"
means an amount  equal to more than  twenty  percent  (20%) but less than  fifty
percent (50%) of "Earnings"  of the  Corporation  for the Fiscal Year within the
meaning of  Statement  of  Financial  Accounting  Concepts No. 5 and shall in no
event exceed "net cash flow from operating activities" within the meaning of FAS
95 for the Fiscal  Year.  Within one hundred and twenty (120) days after the end
of each  fiscal  year during the  Redemption/Cancellation  Period  (the  "Fiscal
Year"), the Board of Directors shall by resolution:  (1) determine whether as of
the  conclusion  of the prior Fiscal Year there were any  "Available  Funds" for
redemption of all or part of the outstanding  Entropin series A Preferred Stock;
and (2)  declare a  specific  amount of such  Available  Funds to be paid by the
Corporation  for  redemption  of  Series  A  Preferred  Stock  (the  "Designated
Available Funds") for that Fiscal Year. The amount of Designated Available Funds
shall be set by the Board of Directors in its sole and absolute  discretion.  In
making the  determination  of the  existence of  Available  Funds for any Fiscal
Year, the designation of Designated  Available Funds for any Fiscal Year, and/or
the decision of any matter  relating  thereto,  the Board of Directors  may rely
upon such  information and advisors they deem necessary and appropriate in their
own judgment and/or pursuant to the provisions of the Articles,  Bylaws, and law
then in effect.

          (b)  DETERMINATION  OF THE NUMBER OF SHARES TO BE  REDEEMED  FROM EACH
HOLDER.  Each  shareholder  holding  Entropin  Series A Preferred Stock shall be
entitled to participate  on a pro rata basis in any mandatory  redemption by the
Corporation  under this  Section  2.4.  The total  number of shares of  Entropin
Series  A  Preferred  Stock  to be  redeemed  in each  Fiscal  Year  during  the
Redemption/Cancellation   Period  shall  be  determined  by  dividing:  (x)  the
Designated  Available  Funds amount for that Fiscal  Year;  by (y) the number of
issued and  outstanding  shares of Entropin  Series A Preferred  Stock as of the
last day of the Fiscal Year for which the redemption is being made.  Each holder
of Entropin  Series A Preferred  Stock subject to redemption for the Fiscal Year
shall be entitled to redemption of shares on a pro rata basis with other holders
of Entropin Series A Preferred Stock subject to redemption at that time.

          (c) NO CUMULATIVE  RIGHTS. The determination of whether there shall be
a mandatory  redemption of Entropin  Series A Preferred Stock shall be made on a
Fiscal Year basis and there shall be no  cumulative  rights to  redemption  on a
year-to-year basis.

          SECTION 2.5.  ELECTIVE  REDEMPTION.  The  Corporation may from time to
time solely at its sole and exclusive option redeem or otherwise  acquire any or
all  outstanding  shares of Entropin  Series A  Preferred  Stock for cash of one
dollar ($1.00) per share. If the Corporation elects to voluntarily redeem shares
under this Section 2.5, every holder of Entropin  Series A Preferred Stock shall
have the  right to cause  the  Corporation  to  redeem  the same  number of that
holder's Entropin Series A Preferred Stock.

          SECTION  2.6.  REDEMPTION  OR  PURCHASE  PRICE.  In  all  events,  the
"Redemption Price" for the redemption or other acquisition by the Corporation of
shares of  Entropin  Series A  Preferred  Stock  shall be $1.00 per share or the
appropriate percentage of $1.00 per share for any fraction of one share.


                                       -3-

<PAGE>

          SECTION  2.7.  NOTICE  OF  REDEMPTION.  The  Corporation  will mail by
registered mail written notice of each redemption of Entropin Series A Preferred
Stock to each record holder of Entropin  Series A Preferred  Stock not more than
60 days after the date the Board of  Directors  approved  the  redemption.  Upon
mailing any notice of  redemption,  the  Corporation  shall become  obligated to
redeem the total number of Entropin Series A Preferred  Stock specified  therein
at the time of  redemption  specified  therein,  which time shall in no event be
later than 90 days after the Board of Directors approved the redemption.

          SECTION 2.8.  EFFECT OF REDEMPTION OR PURCHASE.  Any share of Entropin
Series  A  Preferred  Stock  that  is  redeemed  or  otherwise  acquired  by the
Corporation shall be deemed canceled  immediately upon redemption or acquisition
by the Corporation  without any further act or notice and shall not be reissued,
sold or  transferred.  In case fewer than the total number of Entropin  Series A
Preferred  Stock  shares  represented  by  any  certificate  are  redeemed,  the
Corporation  will issue a new certificate  representing the number of unredeemed
Entropin  Series A Preferred  Stock shares to the holder thereof without cost to
such holder.

          SECTION  2.9.  CANCELLATION.  If  any  shares  of  Entropin  Series  A
Preferred  Stock remains  outstanding  as of 11:59 p.m. (CST) on the 2,555th day
from the date such share was  initially  issued by the  Corporation,  such share
shall  be  deemed  canceled  immediately  without  any  act  or  notice  by  the
Corporation and all rights attendant to such share shall cease.

          SECTION  2.10.  LIQUIDATION  RIGHTS.  In the event of any voluntary or
involuntary  liquidation,  dissolution  or  winding-up  of  the  affairs  of the
Corporation  during  the   Redemption/Cancellation   Period,  after  payment  or
provision for payment of the debts and other liabilities of the Corporation, the
holders of Entropin Series A Preferred Stock shall be entitled to receive, prior
and in preference to any  distribution  of any of the assets or surplus funds of
the  Corporation  to the holders of the Common Stock of the  Corporation  or any
other preferred stock of the Corporation,  by reason of their ownership thereof,
an amount equal to one dollar ($1.00) for each share, as appropriately  adjusted
to reflect any stock split, stock dividend,  combination,  recapitalization  and
the like.

          All  preferential  amounts to be paid to the  holders of the  Entropin
Series A Preferred  Stock under this Section 2.10 shall be paid or set apart for
payment  before the  payment or setting  apart for payment of any amount for (or
the  distribution  of any  assets of the  Corporation  to) the  holders of other
preferred  stock or the Common Stock of the  Corporation in connection with such
liquidation,  dissolution or winding-up and the holders of such other  preferred
stock or the Common Stock of the  Corporation  shall share ratably all remaining
assets of the Corporation with no further right of participation accruing to any
holder of Entropin  Series A Preferred  Stock. If the assets or surplus funds to
be  distributed  to the holders of the  Entropin  Series A  Preferred  Stock are
insufficient  to permit the payment to such  holders of their full  preferential
amount in the event of a  liquidation,  dissolution or winding up of the affairs
of  the  Corporation,  the  assets  and  surplus  funds  legally  available  for
distribution  shall be  distributed  ratably  among the holders of the  Entropin
Series A Preferred Stock in proportion to the full preferential amount each such
holder would otherwise be entitled to receive.

                             CORPORATE OPPORTUNITIES

          The  officers,  directors  and other  members  of  management  of this
Corporation  shall be subject to the  doctrine of corporate  opportunities  only
insofar as it applies to business  opportunities  in which this  Corporation has
expressed an interest as determined from time to time by the Corporation's Board
of Directors as evidenced by resolutions  appearing the  Corporation's  minutes.
When such areas of interest  are  delineated,  all such  business  opportunities
within  such areas of  interest  which come to the  attention  of the  officers,
directors and other members of management of this Corporation shall be disclosed
promptly to this  Corporation  and made  available to it. The Board of Directors
may reject any business opportunity  presented to it and thereafter any officer,
director or other member of management  may avail  himself of such  opportunity.
Until  such  time as this  Corporation,  through  its  Board of  Directors,  has
designated  an area of interest,  the  officers,  directors and other members of
management of this Corporation shall be free to engage in such areas of interest
on their  own and the  provisions  hereof  shall  not  limit  the  rights of any
officer,  director or other member of management of this Corporation to continue
a business  existing  prior to the time that such area of interest is designated
by this  Corporation.  This  provision  shall not be  construed  to release  any
employee  of the  Corporation  (other  than an  officer,  director  or member of
management) from any duties which he may have to the Corporation.

          Whenever a compromise or  arrangement  is proposed by the  Corporation
between  it and  its  creditors  or any  class  of  them,  and/or  between  said
Corporation  and its  shareholders  or any class of them, any court of equitable
jurisdiction may, on the application in a summary way by said Corporation, or by
a majority of its stock,  or on the  application  of any  receiver or  receivers
appointed  for  said   Corporation,   or  on  the  application  of  trustees  in
dissolution,  order a meeting of the  creditors or class of creditors  and/or of
the shareholders or class of shareholders of said  Corporation,  as the case may
be, to be notified in such  manner as the said court  decides.  If a majority in
number,  representing at least three-fourths in amount of the creditors or class
of creditors,  and/or the holders of the majority of the stock or class of stock
of said Corporation,  as the case may be, agree to any compromise or arrangement
and/or to any  reorganization  of said  Corporation,  as a  consequence  of such
compromise or arrangement,  the said  compromise or arrangement  and/or the said
reorganization  shall, if sanctioned by the court to which the said  application
has been made, be binding upon all the  creditors or class of creditors,  and/or
on all the  shareholders or class of shareholders  of said  Corporation,  as the
case may be, and also on said Corporation.

                                  ARTICLE XIII
                             VOTING OF SHAREHOLDERS

Corporation  which  pursuant to statute  require the vote of  two-thirds  of the
outstanding  shares  entitled  to vote  thereon,  a vote or  concurrence  of the
holders of a majority of the  outstanding  shares of the shares entitled to vote

between Vanden Capital Group, Inc., a Colorado  corporation and its subsidiaries
("Vanden")  and Entropin,  Inc., a California  corporation  ("Entropin"),  being

merged with and into Vanden as the surviving  corporation in accordance with the
applicable  laws of  Colorado  and  California,  that the name of the  surviving
corporation  shall  be  Entropin,  Inc.  (which  in its  capacity  as  surviving
corporation is hereinafter  called the  "Surviving  Corporation"),  and that the

be as follows:


                            SECTION 1. EFFECTIVE DATE

     The merger provided for in this Agreement  shall become  effective upon the

<PAGE>



                      SECTION 3. ARTICLES OF INCORPORATION

     The Restated  Articles of  Incorporation of Vanden shall be the Articles of
Incorporation  of the Surviving  Corporation  from and after the Effective Date,
subject  to the right of the  Surviving  Corporation  to amend its  Articles  of
Incorporation in accordance with the laws of the State of Colorado.


                                SECTION 4. BYLAWS

     The Bylaws of the Surviving Corporation shall be the Bylaws of Vanden as in
effect on the date of this Agreement.


                     SECTION 5. MANNER OF CONVERTING SHARES

     5.1 CONVERSION.  The mode of carrying the merger into effect and the manner
and basis of  converting  the shares of Entropin  into  shares of the  Surviving
Corporation are as follows:

         (1) For and in  consideration of the exchange of all shares of Entropin
Common Stock (no par value)  issued and  outstanding  and  Redeemable  NonVoting
Preferred  Stock (no par value) to be issued and  outstanding  on the  Effective
Date:

             (a)    Vanden will  recapitalize its issued and outstanding  shares
                    of Common Stock ($.0001 par value) from 90,015,200 shares to
                    300,050  shares by a reverse split of 1 share for 300 shares
                    and  increase  the par value  thereof to $.001.  Vanden will
                    reduce its 50,000,000  shares of Preferred Stock ($.0001 par
                    value)  to  10,000,000  shares  and  increase  the par value
                    thereof to $.001.  Thereafter,  Vanden will issue  5,700,000
                    shares of new $.001 par value Common  Stock to  shareholders
                    of all  issued  and  outstanding  Entropin  Common  Stock in
                    exchange therefor on a one for one basis.

              (b)   Entropin will authorize and issue  redeemable  eight percent
                    (8%) non-cumulative  non-voting  preferred stock with no par
                    value for an  issuance  value of $1.00 per share in exchange
                    for all liabilities in excess of $350,000  exclusive of; (i)
                    usual and customary  fees  incurred in connection  with this
                    Agreement;  and, (ii) the  obligation due Ed Headrick as set
                    forth  in  Note 4 to  cite  Entropin's  Financial  Statement
                    accompanying  the  November  21, 1997 Report of  Independent
                    Certified Public Accounts provided to Vanden. Such fees will
                    be  paid  from  the   proceeds  of  the  Private   Placement
                    referenced in Section 14.8 hereof.  The preferred stock will
                    be  redeemable  only  from  twenty  percent  (20%)  to fifty
                    percent (50%) of annual  "Earnings",  but not to exceed "Net
                    Cash  Flow  from   Operating   Activities".   The  foregoing
                    capitalized  terms  shall have the  meaning  ascribed  under
                    Generally  Accepted  Accounting  Principles.  The  preferred
                    stock will automatically  cancel in seven years if not fully
                    redeemed within that time period.


                                        2

              (c)   Vanden will issue shares of redeemable  non-voting preferred
                    stock to  holders of an equal  number of shares of  Entropin
                    preferred  stock in  exchange  therefor  on a 1 share  for 1
                    share  basis.  The  Vanden  preferred  stock  shall have the
                    identical terms of the Entropin preferred stock as set forth
                    in Section 5.1(1)(b).

         (2) Each share of Entropin Common Stock and Preferred Stock
which is issued and  outstanding on the Effective  Date shall,  by virtue of the
merger and without any action on the part of Entropin, be retired and cancelled.

         (3) Each  certificate  evidencing  ownership of shares of Vanden Common
Stock  issued and  outstanding  on the  Effective  Date or held by Vanden in its
treasury shall continue to evidence  ownership of the number of shares of Vanden
Common Stock giving effect to the 1-for-300 share Common Stock recapitalization.

     5.2  EXCHANGE  OF  CERTIFICATES.  As  promptly  as  practicable  after  the
Effective  Date,  each  holder of an  outstanding  certificate  or  certificates
theretofore  representing  shares of Entropin  Common Stock and Preferred  Stock
shall surrender the same to Corporate  Securities  Transfer  ("Exchange Agent"),
Denver,  Colorado,  and shall receive in exchange a certificate or  certificates
representing  the number of full  shares of Vanden  Common  Stock into which the
shares  of  Entropin  Common  Stock  and  Preferred  Stock  represented  by  the
certificate or certificates so surrendered shall have been converted.  The name,
address and amount of shares  owned by each holder of Entropin  Common  Stock is
set forth on  Schedule  5.2(a).  The same  information  for  holders of Entropin
Preferred Stock, when issued, will be set forth on Schedule 5.2(b).
