         (a) This statement is being made by Karlton Terry Oil Company ("KTOC"),
Mr.  Karlton  Terry  and  Mr.  Jubal  Terry  (each  a  "Reporting   Person"  and
collectively,   the  "Reporting  Persons").  Karlton  Terry  owns  100%  of  the
outstanding  capital stock of KTOC and is the President and the sole director of
KTOC and Jubal Terry is the Vice  President of KTOC.  This statement on Schedule

<PAGE>



ITEM 3.  SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION.

         Of the Common Stock of the Issuer  specified as  beneficially  owned by
the Reporting  Persons in Item 5, (a) 605,000 shares represent the right of KTOC
to purchase  275,000 shares of Common Stock and 330,000 shares of Class B Common
Stock, par value $.01 per share (the "Class B Stock"), of the Issuer pursuant to
the Second  Francarep  Option  described in Item 4, and (b) the remaining shares
represent  the  right  to  receive  shares  Common  Stock  upon   conversion  of
outstanding  shares of Class B Stock held by the Reporting  Persons as described
in Item 4 and Item 5. None of such shares of Common Stock have been  acquired by
the Reporting  Persons.  All of the Class B Stock owned by the Reporting Persons
was acquired in exchange  for certain oil and gas  exploration  and  development
assets in the Asset Purchase  Transaction  described in Item 4 and no additional
payment is required to be made in connection  with the conversion of the Class B
Stock into Common  Stock.  KTOC  expects to use a portion of the proceeds of the
exercise of the KTOC/Royal  Scot Option  described in Item 4 to pay the exercise
price of the Second  Francarep  Option.  If the Second  Francarep  Option is not
exercised prior to its expiration,  KTOC has not determined what source of funds
it will use to purchase  the  Francarep  Common Stock  subject to the  Francarep
Option described in Item 4.


ITEM 4.  PURPOSE OF TRANSACTION.

Asset Purchase Transaction.

         Pursuant to the Asset Purchase  Agreement,  dated October 19, 1995 (the
"Purchase  Agreement"),  among the  Issuer  (which  at the time was named  Metro
Capital  Corporation),  KTOC,  Karlton  Terry and Jubal  Terry,  KTOC was issued
4,064,565 shares of Class B Stock,  Karlton Terry was issued 1,490,957 shares of
Class B Stock and Jubal  Terry was issued  1,159,353  shares of Class B Stock in
exchange  for  certain  oil  and  gas  exploration  and  production   properties
transferred to the Issuer (the "Asset Purchase Transaction"). As a result of the
Asset Purchase Transaction, KTOC gained voting control of the Issuer and Karlton
Terry became the Chairman of the Board of Directors and President of the Issuer.
As set forth in Article  II(c) of the Articles of  Incorporation  of the Issuer,
commencing 36 months from the closing of the  transactions  contemplated  by the
Purchase  Agreement,  which occurred December 8, 1995, the Class B Stock will be
convertible  on  a  one-for-one   share  basis  into  shares  of  Common  Stock.
Consequently,  on December 8, 1998,  the  Reporting  Persons will be entitled to
convert all of their shares of Class B Stock into Common Stock of the Issuer.

Francarep Option.

         In October 1995, KTOC entered into an Option  Agreement,  dated October
16, 1995, as amended (the "Francarep Option"), between KTOC

                                                             6

<PAGE>



and Francarep,  Inc., a Wyoming  Corporation  ("Francarep"),  in order to induce
Francarep to participate in the Asset  Purchase  Transaction by selling  certain
properties to the Issuer. The Francarep Option requires KTOC to purchase 275,000
shares of Common Stock (the "Francarep  Common Stock") of the Issuer, at a price
of $1.50 per share for a total purchase  price of $412,500.  Francarep also owns
330,000  shares  of the  Issuer's  Class B Stock  that  are not  subject  to the
Francarep Option.

     In  November  1996,  the  Issuer  declared a partial  liquidating  dividend
consisting  of one share of  common  stock of Bishop  Capital  Corporation  (the
"Bishop  Stock"),  a  subsidiary  of the Issuer,  for each four shares of Common
Stock  outstanding (the  "Distribution").  The holders of Class B Stock were not
entitled to participate in the  Distribution.  The  Distribution was declared in
November  1996  and  paid  on or  about  June  20,  1997.  As a  result  of  the
Distribution, Francarep received 68,750 shares of the Bishop Stock.

     In March 1998, in  connection  with the execution of the Royal Scot Options
described below,  KTOC entered into an Option to Purchase,  dated March 20, 1998
(the "Second Francarep Option"),  between KTOC and Francarep,  pursuant to which
Francarep  granted to KTOC an option to purchase  all of the  275,000  shares of
Class B Stock,  the  330,000  shares of Common  Stock and the  68,750  shares of
Bishop Stock owned by Francarep  (collectively,  the "Francarep  Shares") for an
aggregate  purchase price of $250,000.  Of such amount,  KTOC has paid $100,000,
which it received upon the  execution of the  KTOC/Royal  Scot Option  described
below. In the event that the Second  Francarep  Option is not exercised prior to
its expiration,  the obligations of KTOC to purchase the Francarep  Common Stock
pursuant to the  Francarep  Option  will  continue,  except  that the  aggregate
purchase price of $412,500 will be reduced by the amount of any payments made in
respect of the purchase price of the Francarep Shares under the Second Francarep
Option.  In connection  with the  extension of the  expiration of the Royal Scot
Options  described below, the expiration of the Second Francarep Option has been
extended  to March  31,  1999.  The  foregoing  description  of the terms of the
Francarep Option and the Second Francarep Option are qualified in their entirety
by  reference  to the terms of such  Agreements,  which are  attached  hereto as
Exhibits and incorporated herein by reference.

Royal Scot Options.

     In March 1998, pursuant to (a) an Option to Purchase,  dated March 20, 1998
(the  "KTOC/Royal  Scot  Option"),  among Royal Scot Minerals , Inc., a Delaware
corporation ("RSMI"), Karlton Terry, KTOC and Art and Music Outreach for Kids, a
Colorado nonprofit corporation,  and (b) an Option to Purchase,  dated March 20,
1998 (the "Jubal Terry/Royal Scot Option" and, together with the KTOC/Royal Scot
Option,  the "Royal Scot Options"),  between RSMI and Jubal Terry, the Reporting
Persons

                                                             7

<PAGE>



agreed  to sell to Royal  Scot all of the Class B Stock  (and all of the  Common
Stock into which such  Class B Stock may be  converted)  held by them,  together
with the  Francarep  Shares  to be  purchased  by KTOC  pursuant  to the  Second
Francarep  Option.  RSMI paid an option premium of $200,000 for KTOC/Royal  Scot
Option and an option premium of $25,000 for the Jubal  Terry/Royal  Scot Option.
No part of such option  premium for the Royal Scot Options is  attributed to the
option exercise  price.  The option exercise price with respect to the Shares of
Class B Stock held by Karlton Terry and KTOC, together with the Francarep Shares
to be purchased by KTOC pursuant to the Second Francarep Option is $650,000. The
option  exercise price with respect to the Shares of Class B Stock held by Jubal
Terry is  $75,000.  The  initial  terms of the Royal  Scot  Options  expired  on
September  15,  1998,  but have been  extended to March 31, 1998 in exchange for
extension  payments of $25,000,  in the case of the KTOC/Royal Scot Option,  and
$10,000,  in the  case of the  Jubal  Terry/Royal  Scot  Option,  both of  which
extension  payments  are  credited  against the exercise  price.  The  foregoing
description  of the Royal Scot Options is qualified in its entirety by reference
to the terms of such  Agreements,  which are  attached  hereto as  Exhibits  and
incorporated herein by reference.

         Upon the  exercise  of the Royal Scot  Options,  RSMI would own Class B
Stock,  or Common Stock issued upon the conversion of Class B Stock,  sufficient
to confer  upon RSMI  voting  control of the  Issuer.  RSMI has been  engaged in
discussions  with the  Issuer and the  Reporting  Persons  regarding  a possible
business  combination  transaction  and entered  into the Royal Scot  options in
connection with such  discussions,  but no agreement has been reached  regarding
the terms of any such transaction.

         Except as expressly  described above, no Reporting Person has any plans
or proposals  that relate to or would result in any of the actions  described in
subitems (a) through (j) of Item 4 of Schedule 13D.

         (a) The Reporting Persons beneficially own the following securities:

         (i)  KTOC   beneficially  owns  4,354,565  shares,  or  54.6%,  of  the
outstanding Common Stock, including:

         (A)      3,749,565  shares  which  KTOC has the right to  acquire on or
                  after  December 8, 1998 upon  conversion of an equal number of
                  shares of Class B Stock;

         (B)      330,000 shares which KTOC has the right to acquire on or after
                  December 8, 1998 upon conversion of an equal number of

                                                             8

<PAGE>



                  shares of Class B Stock that are indirectly beneficially owned
                  by KTOC as the result of its right to purchase  the  Francarep
                  Shares under the Second Francarep Option; and

         (C)      275,000   shares  of   Common   Stock   that  are   indirectly
                  beneficially  owned by KTOC as the result of its obligation to
                  purchase  the  Francarep  Shares  under the  Second  Francarep
                  Option.

         (ii) Karlton Terry beneficially owns 5,583,022 shares, or 60.3%, of the
outstanding Common Stock, including:

         (A)      1,228,457  shares which Karlton Terry has the right to acquire
                  on or after  December  8,  1998  upon  conversion  of an equal
                  number of shares of Class B Stock; and

         (B)      4,354,565  shares  owned by KTOC as  specified in Item 5(a)(i)
                  and the  beneficial  ownership of which may be  attributed  to
                  Karlton Terry as the sole stockholder and director of KTOC.

         (iii) Jubal Terry  beneficially owns 1,034,353 shares, or 22.2%, of the
outstanding  Common Stock,  all of which represent  shares which Jubal Terry has
the right to acquire on or after  December 8, 1998 upon  conversion  of an equal
number of shares of Class B Stock.

         (iv) None of the  Reporting  Persons or any of the Related  Parties has
any right to acquire any other Common Stock.

         (v) KTOC and Karlton Terry expressly disclaim  beneficial  ownership of
any securities  indicated as owned directly or indirectly by Jubal Terry in Item
5(a)(iii).   Jubal  Terry  expressly  disclaims   beneficial  ownership  of  any
securities  indicated as directly or  indirectly  beneficially  owned by KTOC in
Item 5(a)(i) or by Karlton Terry in Item 5(a)(ii).

     (b)  KTOC  has no  power  to vote or to  direct  the  voting  of any of the
Francarep Shares prior to their purchase by the Reporting Person from Francarep.
Shared  power to dispose  or direct  the  disposition  of the  Francarep  Shares
specified in Item 5(a) may be  attributed  to KTOC by virtue of KTOC's option to
purchase such securities under the Second Francarep Option. Beneficial ownership
and shared voting and dispositive  power of the 4,354,565 shares of Common Stock
owned by KTOC may be  attributed  to Karlton Terry by virtue of his ownership of
100% of KTOC's  outstanding  capital stock and his position as sole director and
president of KTOC. The Reporting  Persons have sole power to vote and to dispose
or direct the  disposition  of all of the other  Securities  indicated  as being
beneficially owned by them in Item 5(a).

     (c) The Reporting  Persons  effected no transactions in the Common Stock in
the past 60 days, other than the acquisition of beneficial

                                                             9

<PAGE>



ownership of the Common Stock  specified in Item 5(a) resulting from the Class B
Common Stock  becoming  convertible  into Common  Stock on December 8, 1998.  No
Reporting  Person  paid any  consideration  in  respect  of its  acquisition  of
beneficial ownership of such Common Stock.

     (d) Francarep is the direct and beneficial  owner of the Francarep  Shares.
To the best  knowledge  of the  Reporting  Person,  Francarep  has the  right to
receive and the power to direct the receipt of dividends  from,  or the proceeds
of the sale of such securities.

     (e) Not applicable.

RESPECT TO SECURITIES OF THE ISSUER.

          The description of the Francarep  Option,  the Second Francarep Option
and the  Royal  Scot  Options  set  forth in Item 4 are  incorporated  herein by

addition to any other  rights or remedies  now or  hereafter  provided by law or

writing,  signed by the party against whom  enforcement  of any waiver,  change,
modification or discharge is sought.

Secured  Party in order (i) to pledge the Shares to Secured  Party,  and (ii) to
grant  and  assign to  Secured  Party a first  priority  lien on,  and  security
interest in, the Shares.

                                    AGREEMENT

        In   consideration   of  the  foregoing  and  other  good  and  valuable
consideration,  the receipt and  sufficiency  of which are hereby  acknowledged,
Debtor hereby agrees as follows for the benefit of Secured Party:

        1.      Certain Definitions.  As used herein, the following terms shall 
have the following respective meanings:

                "Collateral" has the meaning set forth in Section 2 below.

                An "Event of Default"  shall  occur if (i) Debtor  fails to make
any payments  required by the Promissory Note or (ii) Debtor fails to perform or
observe any  obligation or condition to be performed or observed by it hereunder
and such failure remains uncured or unwaived for ten days.

                "Lien" means any lien, mortgage,  pledge,  assignment,  security
interest,  charge or encumbrance of any kind (including any conditional  sale or
other  title  retention  agreement,  any lease in the  nature  thereof,  and any
agreement  to give  any  security  interest)  and any  option,  trust  or  other
preferential arrangement having the practical effect of any of the foregoing.


                                                     Ex. 4-11

     "Proceeds"  means all  proceeds  of,  and all  other  profits,  rentals  or
receipts, in whatever form, arising from the collection,  sale, lease, exchange,
assignment,  licensing  or  other  disposition  of,  or  realization  upon,  the
Collateral, or any portion thereof.

     "Secured  Obligations"  has the  meaning  given to such  term in  Section 3
below.

     "Security Interests" means the security interests in the Collateral granted
hereunder.

     "UCC" means the Uniform  Commercial Code as in effect on the date hereof in
the State of Colorado;  provided  that if by reason of mandatory  provisions  of
law, the perfection or the effect of perfection or nonperfection of the Security
Interests in any  Collateral  is governed by the Uniform  Commercial  Code as in
effect in a jurisdiction other than Colorado, "UCC" means the Uniform Commercial
Code as in effect in such other  jurisdiction  for  purposes  of the  provisions
hereof relating to such perfection or effect of perfection or nonperfection.

        2. The Security  Interests.  To secure the full and punctual  payment or
other  performance  of the  Secured  Obligations  in  accordance  with the terms
thereof,  and to secure  the  performance  of all of the  obligations  of Debtor
hereunder,  Debtor,  to the fullest extent  permitted by law, hereby assigns and
pledges to Secured  Party,  and grants to Secured  Party a  continuing  security
interest in and to, all of the following  property of Debtor,  whether now owned
or existing or hereafter  acquired or arising,  regardless of where located (all
being collectively referred to as the "Collateral"):

                         (i) the Shares and the  certificates  representing  the
        Shares  and any  interest  of Debtor in the  entries on the books of any
        financial  intermediary  pertaining  to the Shares,  and all  dividends,
        cash, warrants,  rights, instruments and other property or proceeds from
        time to time received, receivable or otherwise distributed in respect of
        or in exchange for any or all of the Shares;

                         (ii) any substitute  shares of the capital stock of any
        class issued by AROC to Debtor in exchange for or substitution of any of
        the  Shares  and  the  certificates  representing  such  shares  and any
        interest  of  Debtor  in the  entries  on  the  books  of any  financial
        intermediary  pertaining  to  such  shares,  and  all  dividends,  cash,
        warrants,  rights,  instruments and other property or proceeds from time
        to time received,  receivable or otherwise  distributed in respect of or
        in exchange for any or all of such shares;

                         (iii)  all  Proceeds  of all  or any of the  Collateral
        described in clauses (i) and (ii) above.

        3. Security for Obligations.  This Agreement secures, and the Collateral
is collateral  security for, the prompt  payment or performance in full when due
of all obligations and liabilities of Debtor to make payments  existing under or
arising out of or in connection with the Promissory Note, and all obligations of
every nature of Debtor now or hereafter  existing under this Agreement (all such
obligations of Debtor being the "Secured Obligations").

                                                     Ex. 4-12

<PAGE>




        4. Delivery of the Collateral.  Upon the execution hereof,  Debtor shall
immediately  deliver the stock  certificates  representing the Shares to Secured
Party.

        5.  Transfers  and Other  Liens.  Debtor  shall not,  without  the prior
written consent of Secured Party (which shall not be unreasonably withheld):

     (a) sell, transfer,  assign (by operation of law or otherwise) or otherwise
dispose of any of the Collateral;

     (b) create or suffer to exist at any time any Lien,  security  interest  or
other charge or encumbrance  upon or with respect to the Collateral,  except for
the Security Interests; or

     (c) take any other action in connection  with the Collateral that would (i)
impair the  interests  or rights of Secured  Party under this  Agreement or (ii)
impair or otherwise adversely affect the value of the Collateral.

        6.  Further  Assurances.  Debtor  agrees that from time to time,  at the
expense  of Debtor,  Debtor  will  promptly  execute  and  deliver  all  further
instruments and documents, and take all further action, that may be necessary or
desirable,  or that Secured  Party may request,  in order to perfect and protect
the Security  Interests or to enable  Secured  Party to exercise and enforce its
rights and remedies hereunder with respect to any Collateral.

        7. Voting  Rights;  Dividends,  Etc.  (a) So long as no Event of Default
shall have occurred and be continuing:

                         (i) Debtor  shall be entitled  to exercise  any and all
        voting and other consensual  rights  pertaining to the Collateral or any
        part  thereof for any purpose  not  inconsistent  with the terms of this
        Agreement.

                         (ii) Debtor shall be entitled to receive all  dividends
        and interest paid in respect of the Collateral.

                (b) Upon the occurrence and during the  continuation of an Event
of Default,  upon  written  notice from Secured  Party to Debtor,  all rights of
Debtor to  exercise  the  voting  and  other  consensual  rights  which it would
otherwise be entitled to exercise pursuant to clause 7(a) above shall cease, and
all such  rights  shall  thereupon  become  vested  in  Secured  Party who shall
thereupon  have the sole  right,  but not the  obligation,  to  exercise,  or to
appoint any person to exercise on its behalf,  such voting and other  consensual
rights.

        8. General  Authority.  To the extent  permitted by law,  Debtor  hereby
irrevocably appoints Secured Party its true and lawful attorney, with full power
of substitution, in the name of Debtor, Secured Party or otherwise, for the sole
use and benefit of Secured Party, but at Debtor's expense,  to exercise,  at any
time and from time to time after an Event of Default has

                                                     Ex. 4-13

<PAGE>




first  occurred  and is  continuing,  all or any of the  following  powers  with
respect to all or any of the Collateral:

                (a) to file one or more financing or continuation statements, or
amendments  thereto,  relative to all or any part of the Collateral  without the
signature of Debtor;

                (b) to ask, demand, collect, sue for, recover, compound, receive
and give  acquittance  and receipts for monies due and to become due under or in
respect of any of the Collateral;

                (c) to receive, endorse and collect any instruments made payable
to Debtor  representing  any  dividend,  principal or interest  payment or other
distribution  in respect of the  Collateral or any part thereof and to give full
discharge for the same;

                (d) to file any  claims  or take any  action  or  institute  any
proceedings  that  Secured  Party  may  deem  necessary  or  desirable  for  the
collection  of any of the  Collateral  or  otherwise  to  enforce  the rights of
Secured Party with respect to any of the Collateral; and

                (e) to sell,  transfer,  assign or otherwise deal in or with the
same or the proceeds or avails  thereof,  as fully and effectually as if Secured
Party were the absolute  owner  thereof;  provided that Secured Party shall give
Debtor not less than ten days' prior written notice of the time and place of any
sale  or  other  intended  disposition  of  any of the  Collateral,  except  any
Collateral  which is perishable or threatens to decline  speedily in value or is
of a type  customarily  sold on a  recognized  market.  Debtor  agrees that such
notice  constitutes  "reasonable  notification"  within  the  meaning of Section
9-504(3) of the UCC.

        9.  Remedies  upon an Event of  Default.  (a) If an Event of Default has
occurred and is  continuing,  Secured Party may exercise all rights of a secured
party  under the UCC  (whether or not in effect in the  jurisdiction  where such
rights are  exercised)  and,  in  addition,  Secured  Party may,  without  being
required to give any notice,  except as herein provided or as may be required by
mandatory  provisions of law, sell the  Collateral or any part thereof at public
or private sale, for cash, upon credit or for future delivery,  at such price or
prices  as  Secured  Party  may  deem  satisfactory.  Secured  Party  may be the
purchaser of any or all of the  Collateral so sold at any public sale or private
sale.  Debtor will execute and deliver such documents and take such other action
as Secured Party deems  necessary or advisable so that any such sale may be made
in compliance with law. Upon any such sale Secured Party shall have the right to
deliver,  assign and transfer to the purchaser  thereof the  Collateral so sold.
Each  purchaser  at any  such  sale  shall  hold  the  Collateral  so sold to it
absolutely  and free  from any  claim or right of  Debtor  of  whatsoever  kind,
including  any equity or right of redemption  of Debtor.  Debtor,  to the extent
permitted by law, hereby specifically  waives all rights of redemption,  stay or
appraisal  which it has or may have  under  any law now  existing  or  hereafter
adopted. Secured Party, instead of exercising the power of sale herein conferred
upon it,  may  proceed by a suit or suits at law or in equity to  foreclose  the
Security  Interests and sell the  Collateral,  or any portion  thereof,  under a
judgment or decree of a court or courts of competent jurisdiction. Provided that
if the default

                                                     Ex. 4-14

<PAGE>




has been remedied  before the Secured Party has taken any action with respect to
the Collateral, all rights under this Agreement will be restored to the Debtor.

        10.  Application of Proceeds.  Except as expressly provided elsewhere in
this  Agreement,  all proceeds  received by Secured Party in respect of any sale
of, collection from, or other realization upon all or any part of the Collateral
may, in the discretion of Secured Party,  be held by Secured Party as Collateral
for,  and/or  then,  or at any time  thereafter,  applied  in full or in part by
Secured  Party  against,  the  Secured  Obligations  in the  following  order of
priority:

     FIRST: to the payment of all costs and expenses of such sale, collection or
other realization,  including  reasonable  compensation to Secured Party and its
agents and counsel,  and all other  expenses,  liabilities  and advances made or
incurred by Secured  Party in  connection  therewith,  and all amounts for which
Secured Party is entitled to payment  hereunder and all advances made by Secured
Party  hereunder for the account of Debtor,  and to the payment of all costs and
expenses paid or incurred by Secured  Party in  connection  with the exercise of
any right or remedy hereunder, all in accordance with Section 11 below;

     SECOND:  to the payment of all other Secured  Obligations  in such order as
Secured Party shall elect; and

     THIRD: to the payment to or upon the order of Debtor,  or to whomsoever may
be lawfully entitled to receive the same or as a court of competent jurisdiction
may direct, of any surplus then remaining from such proceeds.

        11. Expenses.  Debtor shall, on demand,  pay to Secured Party the amount
of any and all out-of-pocket  expenses,  including the fees and disbursements of
counsel and any other experts,  which Secured Party may incur in connection with
(a) the  administration  or enforcement of this  Agreement,  including,  but not
limited to, such  expenses as Secured  Party incurs to preserve the value of the
Collateral  and  the  validity,  perfection,  rank  and  value  of any  Security
Interests; (b) the custody, preservation,  collection, sale or other disposition
of any of the Collateral; (c) the exercise by Secured Party of any of the rights
conferred  upon it hereunder;  or (d) any Event of Default.  All sums so paid or
incurred by Secured  Party for any of the  foregoing  and any and all other sums
for which  Debtor  may  become  liable  hereunder  and all  costs  and  expenses
(including  attorneys' fees, legal expenses and court costs) reasonably incurred
by Secured Party in enforcing or protecting the Security Interests or any of its
rights or remedies under this Agreement,  shall,  together with interest thereon
until  paid  at  the  rate  of 18  percent  per  annum,  be  additional  Secured
Obligations hereunder.

        12. Termination of Security Interests;  Release of Collateral.  Upon the
payment in full of all of the Secured Obligations,  the Security Interests shall
terminate and all rights to the Collateral shall revert to Debtor. Upon any such
termination of such Security  Interests and release of the  Collateral,  Secured
Party  shall,  at the expense of Debtor,  (a) execute and deliver to Debtor such
documents  as are  reasonably  necessary  to evidence  the  termination  of such
Security  Interests  and the  release of such  Collateral  and (b)  deliver  any
certificates  evidencing  the  Shares and any other  Collateral  held by Secured
Party or its nominees to Debtor.

<PAGE>




        13.     Miscellaneous.

                (a) Waivers;  Non-Exclusive  Remedies. No failure on the part of
Secured Party to exercise,  and no delay in exercising  and no course of dealing
with  respect  to, any right  under  this  Agreement  shall  operate as a waiver
thereof,  nor shall any single or partial exercise by Secured Party of any right
under  this  Agreement  or any other  document  preclude  any  other or  further
exercise thereof or the exercise of any other right. The rights and remedies set
forth in this  Agreement and the  Shareholders  Agreement are cumulative and are
not exclusive of any other remedies available at law or in equity.

                (b) Successors and Assigns. This Agreement is for the benefit of
Secured Party and its successors and assigns. This Agreement shall be binding on
Debtor and its successors and assigns.

                (c) Changes in Writing. Neither this Agreement nor any provision
hereof may be changed,  waived,  discharged or  terminated,  except by a written
agreement signed by Debtor and Secured Party.

                (d)  Severability.   If  any  provision  hereof  is  invalid  or
unenforceable in any jurisdiction, then, to the fullest extent permitted by law,
(a) the other  provisions  hereof  shall remain in full force and effect in such
jurisdiction  and shall be construed to carry out the  intentions of the parties
hereto as nearly as may be possible and (b) the  invalidity or  unenforceability
of any  provision  hereof in any  jurisdiction  shall not affect the validity or
enforceability of such provision in any other jurisdiction.

                (e) Headings.  Section and subsection headings in this Agreement
are included for  convenience  of reference only and shall not constitute a part
of this Agreement for any other purpose or be given any substantive effect.

                (f)  Governing  Law.  THIS  AGREEMENT  SHALL BE GOVERNED BY, AND
SHALL BE CONSTRUED  AND ENFORCED IN  ACCORDANCE  WITH,  THE INTERNAL LAWS OF THE
STATE OF COLORADO, WITHOUT REGARD TO PRINCIPLES OF CONFLICTS OF LAW.

                (g) Counterparts.  This Agreement may be executed in one or more
counterparts and by different parties hereto in separate  counterparts,  each of
which when so executed and delivered  shall be deemed an original,  but all such
counterparts  together  shall  constitute  but  one  and  the  same  instrument;
signature pages may be detached from multiple separate counterparts and attached
to a single  counterpart so that all signature pages are physically  attached to
the same document.

        IN WITNESS WHEREOF,  Debtor and Secured Party have caused this Agreement
to be duly executed and delivered by their  respective  officers  thereunto duly
authorized as of the date first written above.

     "Proceeds"  means all  proceeds  of,  and all  other  profits,  rentals  or
receipts, in whatever form, arising from the collection,  sale, lease, exchange,
assignment,  licensing  or  other  disposition  of,  or  realization  upon,  the
Collateral, or any portion thereof.

     "Secured  Obligations"  has the  meaning  given to such  term in  Section 3
below.

     "Security Interests" means the security interests in the Collateral granted
hereunder.

     "UCC" means the Uniform  Commercial Code as in effect on the date hereof in
the State of Colorado;  provided  that if by reason of mandatory  provisions  of
law, the perfection or the effect of perfection or nonperfection of the Security
Interests in any  Collateral  is governed by the Uniform  Commercial  Code as in
effect in a jurisdiction other than Colorado, "UCC" means the Uniform Commercial
Code as in effect in such other  jurisdiction  for  purposes  of the  provisions
hereof relating to such perfection or effect of perfection or nonperfection.

        2. The Security  Interests.  To secure the full and punctual  payment or
other  performance  of the  Secured  Obligations  in  accordance  with the terms
thereof,  and to secure  the  performance  of all of the  obligations  of Debtor
hereunder,  Debtor,  to the fullest extent  permitted by law, hereby assigns and
pledges to Secured  Party,  and grants to Secured  Party a  continuing  security
interest in and to, all of the following  property of Debtor,  whether now owned
or existing or hereafter  acquired or arising,  regardless of where located (all
being collectively referred to as the "Collateral"):

                         (i) the Shares and the  certificates  representing  the
        Shares  and any  interest  of Debtor in the  entries on the books of any
        financial  intermediary  pertaining  to the Shares,  and all  dividends,
        cash, warrants,  rights, instruments and other property or proceeds from
        time to time received, receivable or otherwise distributed in respect of
        or in exchange for any or all of the Shares;

                         (ii) any substitute  shares of the capital stock of any
        class issued by AROC to Debtor in exchange for or substitution of any of
        the  Shares  and  the  certificates  representing  such  shares  and any
        interest  of  Debtor  in the  entries  on  the  books  of any  financial
        intermediary  pertaining  to  such  shares,  and  all  dividends,  cash,
        warrants,  rights,  instruments and other property or proceeds from time
        to time received,  receivable or otherwise  distributed in respect of or
        in exchange for any or all of such shares;

                         (iii)  all  Proceeds  of all  or any of the  Collateral
        described in clauses (i) and (ii) above.

        3. Security for Obligations.  This Agreement secures, and the Collateral
is collateral  security for, the prompt  payment or performance in full when due
of all obligations and liabilities of Debtor to make payments  existing under or
arising out of or in connection with the Promissory Note, and all obligations of
every nature of Debtor now or hereafter  existing under this Agreement (all such
obligations of Debtor being the "Secured Obligations").

                                                     Ex. 5-9

<PAGE>




        4. Delivery of the Collateral.  Upon the execution hereof,  Debtor shall
immediately  deliver the stock  certificates  representing the Shares to Secured
Party.

        5.  Transfers  and Other  Liens.  Debtor  shall not,  without  the prior
written consent of Secured Party (which shall not be unreasonably withheld):

     (a) sell, transfer,  assign (by operation of law or otherwise) or otherwise
dispose of any of the Collateral;

     (b) create or suffer to exist at any time any Lien,  security  interest  or
other charge or encumbrance  upon or with respect to the Collateral,  except for
the Security Interests; or

     (c) take any other action in connection  with the Collateral that would (i)
impair the  interests  or rights of Secured  Party under this  Agreement or (ii)
impair or otherwise adversely affect the value of the Collateral.

        6.  Further  Assurances.  Debtor  agrees that from time to time,  at the
expense  of Debtor,  Debtor  will  promptly  execute  and  deliver  all  further
instruments and documents, and take all further action, that may be necessary or
desirable,  or that Secured  Party may request,  in order to perfect and protect
the Security  Interests or to enable  Secured  Party to exercise and enforce its
rights and remedies hereunder with respect to any Collateral.

        7. Voting  Rights;  Dividends,  Etc.  (a) So long as no Event of Default
shall have occurred and be continuing:

                         (i) Debtor  shall be entitled  to exercise  any and all
        voting and other consensual  rights  pertaining to the Collateral or any
        part  thereof for any purpose  not  inconsistent  with the terms of this
        Agreement.

                         (ii) Debtor shall be entitled to receive all  dividends
        and interest paid in respect of the Collateral.

                (b) Upon the occurrence and during the  continuation of an Event
of Default,  upon  written  notice from Secured  Party to Debtor,  all rights of
Debtor to  exercise  the  voting  and  other  consensual  rights  which it would
otherwise be entitled to exercise pursuant to clause 7(a) above shall cease, and
all such  rights  shall  thereupon  become  vested  in  Secured  Party who shall
thereupon  have the sole  right,  but not the  obligation,  to  exercise,  or to
appoint any person to exercise on its behalf,  such voting and other  consensual
rights.

        8. General  Authority.  To the extent  permitted by law,  Debtor  hereby
irrevocably appoints Secured Party its true and lawful attorney, with full power
of substitution, in the name of Debtor, Secured Party or otherwise, for the sole
use and benefit of Secured Party, but at Debtor's expense,  to exercise,  at any
time and from time to time after an Event of Default has

                                                     Ex. 5-10

<PAGE>




first  occurred  and is  continuing,  all or any of the  following  powers  with
respect to all or any of the Collateral:

                (a) to file one or more financing or continuation statements, or
amendments  thereto,  relative to all or any part of the Collateral  without the
signature of Debtor;

                (b) to ask, demand, collect, sue for, recover, compound, receive
and give  acquittance  and receipts for monies due and to become due under or in
respect of any of the Collateral;

                (c) to receive, endorse and collect any instruments made payable
to Debtor  representing  any  dividend,  principal or interest  payment or other
distribution  in respect of the  Collateral or any part thereof and to give full
discharge for the same;

                (d) to file any  claims  or take any  action  or  institute  any
proceedings  that  Secured  Party  may  deem  necessary  or  desirable  for  the
collection  of any of the  Collateral  or  otherwise  to  enforce  the rights of
Secured Party with respect to any of the Collateral; and

                (e) to sell,  transfer,  assign or otherwise deal in or with the
same or the proceeds or avails  thereof,  as fully and effectually as if Secured
Party were the absolute  owner  thereof;  provided that Secured Party shall give
Debtor not less than ten days' prior written notice of the time and place of any
sale  or  other  intended  disposition  of  any of the  Collateral,  except  any
Collateral  which is perishable or threatens to decline  speedily in value or is
of a type  customarily  sold on a  recognized  market.  Debtor  agrees that such
notice  constitutes  "reasonable  notification"  within  the  meaning of Section
9-504(3) of the UCC.

        9.  Remedies  upon an Event of  Default.  (a) If an Event of Default has
occurred and is  continuing,  Secured Party may exercise all rights of a secured
party  under the UCC  (whether or not in effect in the  jurisdiction  where such
rights are  exercised)  and,  in  addition,  Secured  Party may,  without  being
required to give any notice,  except as herein provided or as may be required by
mandatory  provisions of law, sell the  Collateral or any part thereof at public
or private sale, for cash, upon credit or for future delivery,  at such price or
prices  as  Secured  Party  may  deem  satisfactory.  Secured  Party  may be the
purchaser of any or all of the  Collateral so sold at any public sale or private
sale.  Debtor will execute and deliver such documents and take such other action
as Secured Party deems  necessary or advisable so that any such sale may be made
in compliance with law. Upon any such sale Secured Party shall have the right to
deliver,  assign and transfer to the purchaser  thereof the  Collateral so sold.
Each  purchaser  at any  such  sale  shall  hold  the  Collateral  so sold to it
absolutely  and free  from any  claim or right of  Debtor  of  whatsoever  kind,
including  any equity or right of redemption  of Debtor.  Debtor,  to the extent
permitted by law, hereby specifically  waives all rights of redemption,  stay or
appraisal  which it has or may have  under  any law now  existing  or  hereafter
adopted. Secured Party, instead of exercising the power of sale herein conferred
upon it,  may  proceed by a suit or suits at law or in equity to  foreclose  the
Security  Interests and sell the  Collateral,  or any portion  thereof,  under a
judgment or decree of a court or courts of competent jurisdiction. Provided that
if the default

                                                     Ex. 5-11

<PAGE>




has been remedied  before the Secured Party has taken any action with respect to
the Collateral, all rights under this Agreement will be restored to the Debtor.


        10.  Application of Proceeds.  Except as expressly provided elsewhere in
this  Agreement,  all proceeds  received by Secured Party in respect of any sale
of, collection from, or other realization upon all or any part of the Collateral
may, in the discretion of Secured Party,  be held by Secured Party as Collateral
for,  and/or  then,  or at any time  thereafter,  applied  in full or in part by
Secured  Party  against,  the  Secured  Obligations  in the  following  order of
priority:

     FIRST: to the payment of all costs and expenses of such sale, collection or
other realization,  including  reasonable  compensation to Secured Party and its
agents and counsel,  and all other  expenses,  liabilities  and advances made or
incurred by Secured  Party in  connection  therewith,  and all amounts for which
Secured Party is entitled to payment  hereunder and all advances made by Secured
Party  hereunder for the account of Debtor,  and to the payment of all costs and
expenses paid or incurred by Secured  Party in  connection  with the exercise of
any right or remedy hereunder, all in accordance with Section 11 below;

     SECOND:  to the payment of all other Secured  Obligations  in such order as
Secured Party shall elect; and

     THIRD: to the payment to or upon the order of Debtor,  or to whomsoever may
be lawfully entitled to receive the same or as a court of competent jurisdiction
may direct, of any surplus then remaining from such proceeds.

        11. Expenses.  Debtor shall, on demand,  pay to Secured Party the amount
of any and all out-of-pocket  expenses,  including the fees and disbursements of
counsel and any other experts,  which Secured Party may incur in connection with
(a) the  administration  or enforcement of this  Agreement,  including,  but not
limited to, such  expenses as Secured  Party incurs to preserve the value of the
Collateral  and  the  validity,  perfection,  rank  and  value  of any  Security
Interests; (b) the custody, preservation,  collection, sale or other disposition
of any of the Collateral; (c) the exercise by Secured Party of any of the rights
conferred  upon it hereunder;  or (d) any Event of Default.  All sums so paid or
incurred by Secured  Party for any of the  foregoing  and any and all other sums
for which  Debtor  may  become  liable  hereunder  and all  costs  and  expenses
(including  attorneys' fees, legal expenses and court costs) reasonably incurred
by Secured Party in enforcing or protecting the Security Interests or any of its
rights or remedies under this Agreement,  shall,  together with interest thereon
until  paid  at  the  rate  of 18  percent  per  annum,  be  additional  Secured
Obligations hereunder.

        12. Termination of Security Interests;  Release of Collateral.  Upon the
payment in full of all of the Secured Obligations,  the Security Interests shall
terminate and all rights to the Collateral shall revert to Debtor. Upon any such
termination of such Security  Interests and release of the  Collateral,  Secured
Party  shall,  at the expense of Debtor,  (a) execute and deliver to Debtor such
documents  as are  reasonably  necessary  to evidence  the  termination  of such
Security

                                                     Ex. 5-12

<PAGE>




Interests and the release of such  Collateral  and (b) deliver any  certificates
evidencing  the Shares  and any other  Collateral  held by Secured  Party or its
nominees to Debtor.

        13.     Miscellaneous.

                (a) Waivers;  Non-Exclusive  Remedies. No failure on the part of
Secured Party to exercise,  and no delay in exercising  and no course of dealing
with  respect  to, any right  under  this  Agreement  shall  operate as a waiver
thereof,  nor shall any single or partial exercise by Secured Party of any right
under  this  Agreement  or any other  document  preclude  any  other or  further
exercise thereof or the exercise of any other right. The rights and remedies set
forth in this  Agreement and the  Shareholders  Agreement are cumulative and are
not exclusive of any other remedies available at law or in equity.

                (b) Successors and Assigns. This Agreement is for the benefit of
Secured Party and its successors and assigns. This Agreement shall be binding on
Debtor and its successors and assigns.

                (c) Changes in Writing. Neither this Agreement nor any provision
hereof may be changed,  waived,  discharged or  terminated,  except by a written
agreement signed by Debtor and Secured Party.

                (d)  Severability.   If  any  provision  hereof  is  invalid  or
unenforceable in any jurisdiction, then, to the fullest extent permitted by law,
(a) the other  provisions  hereof  shall remain in full force and effect in such
jurisdiction  and shall be construed to carry out the  intentions of the parties
hereto as nearly as may be possible and (b) the  invalidity or  unenforceability
of any  provision  hereof in any  jurisdiction  shall not affect the validity or
enforceability of such provision in any other jurisdiction.

                (e) Headings.  Section and subsection headings in this Agreement
are included for  convenience  of reference only and shall not constitute a part
of this Agreement for any other purpose or be given any substantive effect.

                (f)  Governing  Law.  THIS  AGREEMENT  SHALL BE GOVERNED BY, AND
SHALL BE CONSTRUED  AND ENFORCED IN  ACCORDANCE  WITH,  THE INTERNAL LAWS OF THE
STATE OF COLORADO, WITHOUT REGARD TO PRINCIPLES OF CONFLICTS OF LAW.

                (g) Counterparts.  This Agreement may be executed in one or more
counterparts and by different parties hereto in separate  counterparts,  each of
which when so executed and delivered  shall be deemed an original,  but all such
counterparts  together  shall  constitute  but  one  and  the  same  instrument;
signature pages may be detached from multiple separate counterparts and attached
to a single  counterpart so that all signature pages are physically  attached to
the same document.
