                  the common  stock of Rio Grande (the "Rio  Common  Stock") and
                  received approximately 4,070,833 shares of Rio Common Stock;

         2.       Coastal L.P. purchased  approximately  1,041,667 shares of Rio

                  or assume the note payable associated therewith.  The funds to

                  of the Company.

                  Upon   the   completion   of   the   three    above-referenced
         transactions,  the total  number of shares of Rio Common  Stock held by
         Coastal L.P. was in excess of 15,500,000.

Item 4.  Purpose of Transaction.

         Except  as set  forth  below,  the  information  set forth in Item 4 of
Amendment No. 7 is incorporated herein by reference.

                    "(a) In connection  with the  acquisition  by the Company of
          approximately  80.74% of the  outstanding  shares of Rio Common  Stock
          (the "Rio  Acquisition"),  the Company and Coastal L.P. entered into a
          Securities  Purchase  Agreement  dated as of  October  11,  1996  (the
          "Securities  Purchase  Agreement"),  whereby Coastal L.P.  contributed
          15,500,000  shares of its shares of Rio Common Stock to the Company in
          exchange for 22,475,000 newly issued shares of the Common Stock of the
          Company, based on an exchange ratio of 1 share of Rio Common Stock for
          1.45 shares of the Common Stock of the Company. Upon the completion of
          the  series of  transactions  undertaken  in  connection  with the Rio
          Acquisition, Coastal L.P. had increased its ownership of shares of the
          Common Stock of the Company to  22,411,609  shares,  which  represents
          approximately  80.07%  of  the  currently  outstanding  shares  of the
          Company.

                    Also in connection with the Rio Acquisition, the Company and
          Rio  Grande  entered  into a Warrant  Purchase  Agreement  dated as of
          October 11, 1996 (the "Warrant Purchase Agreement"), pursuant to which
          the Company agreed to cancel the  Settlement  Warrants in exchange for
          an additional 9,000,000 shares of Rio Common Stock.

                    The Company and Rio Grande also entered into an Agreement of
          Purchase and Sale of Real  Property  dated as of October 11, 1996 (the
          "Red  Hills  Agreement",  collectively  with the  Securities  Purchase
          Agreement  and  the  Warrant  Agreement,   the  "Contribution  Plan").
          Pursuant to the Red Hills  Agreement,  the Company  sold the Red Hills
          Rights to Rio Grande in exchange  for  2,500,000  shares of Rio Common
          Stock.  At the time of this  transaction,  the Red Hills  property was
          carried on the Company's  balance sheet at a value of $116,000 and was
          subject to a three-year  option by Rio Grande to purchase the property
          for $600,000.

                    Pursuant to the  Contribution  Plan,  the  Company  acquired
          27,000,000 shares of Rio Common Stock, which represented approximately
          80.74% of the outstanding shares of Rio Common Stock.

                    As of  October  31,  1995,  the date of the  Company's  most
          recent fiscal year, it had available net operating loss  carryforwards
          for federal  income tax purposes of  approximately  $17 million  which
          expire in varying  amounts from 1997 through  2010. As a result of the
          transactions  described above, the Company's  ability to utilize fully
          such losses in the future may be significantly limited.

                    As of  July  31,  1996,  the  date  of Rio  Grande's  latest
          unaudited financial  statements,  Rio Grande had total assets of $2.26
          million and total stockholders'  equity of $1.19 million. For the nine
          months ended July 31, 1996 and from  inception  on September  28, 1992
          through July 31, 1996, Rio Grande  incurred net losses of $389,000 and
          $1011,000, respectively.

                    Prior  to the  completion  of  the  Contribution  Plan,  the
          Company   obtained  an  Opinion  from   Westerly   Partners  that  the
          consideration to be received by the Company pursuant to

                               Page 11 of 59 Pages


<PAGE>


          the  Contribution  Plan is fair to the holders of the Common  Stock of
          the Company from a financial point of view.

                    Coastal L.P.'s interest in participating in the Contribution
          Plan was  based,  in part,  on its  desire  to  convert  its  indirect
          investment  in certain  property and leases for a closed  silver mine,
          known as the  "Shafter  Project",  located near  Shafter,  in Presidio
          County,  Texas,  from an interest in a privately-held  company into an
          interest in a publicly-held  company,  which the management of Coastal
          L.P.  believes may offer Coastal L.P.  advantages in the evaluation of
          the  Shafter   Project  and  may   eventually  aid  in  any  potential
          disposition  of the Shafter  Project.  In addition,  the management of
          Coastal L.P.  believes the value of the assets related to both the Red
          Hills  Rights and the  Shafter  Project  could be  enhanced if the two
          assets were held under common ownership.

                    The  management  of Coastal L.P. is aware that the Company's
          management intends to explore potential  refinancing  opportunities in
          Canada,  the U.S.,  Europe and Asia and may also entertain  offers for
          joint ventures or  opportunities  to sell all or part of its assets or
          stock. 

                    Except as described  above,  the filing  persons do not have
          any current plans or proposals which relate to or would result in: (a)
          the  acquisition  by any  of  them  of  additional  securities  of the
          Company,  or the disposition of the securities of the Company;  (b) an
          extraordinary corporate transaction,  such as a merger, reorganization
          or liquidation,  involving the Company or any of its subsidiaries; (c)
          a sale or  transfer  of a material  amount of assets of the Company or
          any of its  subsidiaries;  (d) any  change  in the  present  board  of
          directors  or  management  of the  Company,  including  any  plans  or
          proposals  to change  the number or term or  directors  or to fill any
          existing  vacancies  on the  board;  (e) any  material  change  in the
          present  capitalization  or dividend  policy of the  Company;  (f) any
          other  material   change  in  the  Company's   business  or  corporate
          structure;  (g)  changes in the  Company's  charter or bylaws or other
          actions which may impede the  acquisition of control of the Company by
          any  person;  (h) causing a class of  securities  of the Company to be
          delisted from a national securities exchange or cease to be authorized
          to be  quoted in an  inter-dealer  quotation  system  of a  registered
          national securities  association;  (i) a class of equity securities of
          the Company becoming eligible for termination of registration pursuant
          to Section  12(g)(4) of the Exchange Act; or (j) any action similar to
          those enumerated above.

                    Notwithstanding  the  foregoing,  each of the Filing Persons
          reserves  the  right to take  such  action  in the  future as it deems
          necessary  or  desirable  in  connection  with its  investment  in the
          Company.

Item 5.  Interest in Securities of Issuer.

         (a)-(b) Cole has the right to purchase 50,000 shares of Common Stock at
a price of $.15 per share under the Assigned  Warrants.  Cole also has the right
to purchase 50,000 shares of Common Stock at a price of $.20 per share under the
Issued  Warrants.  As described  in Item 4 of Amendment  No. 6, Cole has entered
into the Cole Voting  Agreement  which gives Coastal LP the right to direct Cole
in his voting of any shares of Common Stock he hereafter acquires by exercise of
the Cole Warrants.  The number of shares of Common Stock  beneficially  owned by
Cole represents  approximately 0.4% of the shares of Common Stock which would be
issued and outstanding upon exercise of the Cole Warrants.

                  Leibsker  has the right to purchase  400,000  shares of Common
Stock at a price of $.18 per share under the "Old  Leibsker  Warrant."  Leibsker
also has the right to purchase  75,000 shares of Common Stock at a price of $.20
per  share  under  the  "New  Leibsker  Warrant"  (with a right to  purchase  an
additional  75,000 shares  vesting on June 28, 1997).  Leibsker also owns 51,030
shares of Common Stock. Caffey has the right to purchase 50,000 shares of Common
Stock at a price of $.20 per share under the "New Caffey  Warrant" (with a right
to purchase up to an  additional  50,000 shares  vesting on June 28,  1997).  As
described in Item 4 of Amendment  No. 5, Leibsker and Caffey have entered into a
shareholders  agreement  which gives Coastal LP the right to direct Leibsker and
Caffey in their  voting of any shares of Common  Stock they now own or hereafter
acquire by exercise of their

                               Page 12 of 59 Pages

<PAGE>

respective warrants. The numbers of shares of Common Stock beneficially owned by
Leibsker and Caffey represent approximately 1.8% and 0.2%, respectively,  of the
shares of Common Stock which would be issued and  outstanding  upon  exercise of
the relevant warrants held by each of Leibsker and Caffey, which include the Old
Leibsker Warrant, the New Leibsker Warrant and the New Caffey Warrant
(collectively, the "Leibsker/Caffey Warrants").

                  Morris and Gan each have the right to purchase  150,000 shares
of Common Stock under their respective warrants  (collectively,  the "Morris/Gan
Warrants").  Pursuant to a voting  agreement  entered  into with  Coastal LP, as
described  in Item 4 of  Amendment  No.  4,  Coastal  LP has the right to direct
Morris and Gan in their  voting of any shares they  acquire by exercise of their
respective warrants.  The number of shares of Common Stock beneficially owned by
Morris and Gan,  after the  exercise of their  respective  warrants,  represents
approximately 0.5% and 0.5%,  respectively,  of the shares of Common Stock which
would then be issued and outstanding.

                  After  giving  effect  to  its   assignment  of  the  Assigned
Warrants,  the Fraser  Warrants and the HRI Warrants,  as described in Item 3 of
Amendment No. 6, Coastal LP has the right to purchase 1,063,332 shares of Common
Stock under the Coastal  Warrants,  which are currently  exercisable at $.15 per
share, and owns 22,411,609 shares of Common Stock. Coastal LP has the sole power
to vote or to direct  the vote and the sole  power to  dispose  or to direct the
disposition of the Coastal  Warrants and the Common Stock acquired upon exercise
of the Coastal Warrants.  Coastal LP has shared power to vote or direct the vote
of 51,030 shares of Common Stock now owned by Leibsker, 100,000 shares of Common
Stock that may be acquired by Cole upon exercise of the Cole  Warrants,  525,000
shares of Common Stock that may be acquired by Leibsker and Caffey upon exercise
of the  Leibsker/Caffey  Warrants and 300,000 shares of Common Stock that may be
acquired by Morris and Gan upon exercise of the Morris/Gan Warrants.

                  The  number of shares of Common  Stock  beneficially  owned by
Coastal LP  represents  approximately  81.6% of the shares of Common Stock which
would  be  issued  and  outstanding  upon  exercise  of the Cole  Warrants,  the
Leibsker/Caffey  Warrants,  the  Morris/Gan  Warrants and the remaining  Coastal
Warrants.

                             SECURED PROMISSORY NOTE


$250,000.                                     As of  October  , 1996
                                              Sonoma, California

                  FOR VALUE RECEIVED, Coastal Capital Partners, L.P., a Delaware
limited  partnership  having its principal place of business at 101 Morgan Lane,
Plainsboro,  New Jersey 08536 (the "Maker")  hereby promises to pay to the order
of Rio Grande Mining Company, a Nevada corporation having its principal place of
business at 539 Broadway,  Sonoma, California 95476 (hereinafter,  the "Payee"),
on March 1, 1997 the unpaid outstanding  principal amount hereof,  together with
interest from and including the date hereof on the unpaid outstanding  principal
balance  hereof at a rate per annum equal to 8.5%.  Maker  shall make  principal
repayments  to Payee of $50,000 on each of November  1, 1996,  December 1, 1996,
January 1, 1997,  February 1, 1997 and March 1, 1997 (each,  a "Payment  Date").
Accrued and unpaid interest may be payable in arrears, at the election of Maker,
either on the Payments  Dates or on the date when the principal  amount shall be
paid in full (whether by prepayment,  by  acceleration  or otherwise).  Interest
shall be computed on the basis of a 365-day  year and the actual  number of days
elapsed.  Notwithstanding anything herein to the contrary, in no event shall the
interest charged, reserved and/or taken on the loans evidenced hereby exceed the
maximum allowed by and determined in accordance with applicable law.

                  This  Note  may be  prepaid  in full  or in  part at any  time
without  premium  or  penalty,  as long as the  interest  then due on the amount
repaid is also paid.

                  All payments received  hereunder shall be applied first to the
payment of accrued  interest and any expenses or charges  payable  hereunder and
the balance, if any, to principal.

                  In the event that the Maker shall fail to make full and timely
payment of any principal or interest hereunder, then the entire unpaid principal
amount of this Note  shall  automatically  become  immediately  due and  payable
without demand or notice,  and the holder may proceed to protect and enforce his
rights  hereunder  by an  action at law,  suit in  equity  or other  appropriate
proceeding, in the holder's sole discretion.

                  In the event of any failure to make a full and timely  payment
of any amount due under this Note,  or if any other event  rendering  the entire
unpaid  principal  amount of this Note  immediately due and payable shall occur,
Maker will pay to the Payee such further  amount as shall be sufficient to cover
all costs and expenses  directly or indirectly  incurred in connection  with any
action  relating  to  collection  of this Note  and/or  the  enforcement  of the
holder's   rights  with   respect  to,  or  the   administration,   supervision,
preservation,  protection of, or realization upon, any property securing payment
hereof (including  expenses incurred in the defense of counterclaims  whether or
not  related  to this  Note),  including  but not  limited to  attorneys'  fees,
expenses and disbursements.

                  The  obligation of Maker to pay all amounts due and payable by
Maker  hereunder is secured by the pledge by Maker to Payee of 1,041,667  shares
of common stock of Payee issued to Maker in  connection  with the  execution and
delivery of the Secured Promissory Note.

                  This  Secured   Promissory   Note  shall  be  the  nonrecourse
obligation of Maker,  and Payee shall have no recourse to the personal assets of
any partner of Maker in connection  with any and all of the obligations of Maker
hereunder.

                  No course of dealing and no delay on the part of the holder of
this Note in  exercising  any right,  power or remedy shall  operate as a waiver
thereof or otherwise prejudice any of such holder's rights, powers and remedies,
and no single or partial  exercise of a right,  power or remedy shall preclude a
further exercise thereof or the exercise of another right, power or remedy.

                  Maker hereby waives trial by jury,  presentment and demand for
payment, notice of non-payment or dishonor,  protest, notice of protest, and all
other  notices  or  demands  in  connection   with  the  delivery,   acceptance,
performance, default or enforcement of payment of this Note.

                  Maker shall not have any right to offset any  payments  due to
the holder hereunder  against any amounts claimed to be owed to holder hereunder
or  otherwise,  but shall be required  to  continue to make all  payments to the
holder when due hereunder.

                  This Note may not be altered  or  amended  except by a writing
duly signed by the party against whom such  alteration or amendment is sought to
be enforced. All of the terms and provisions of this Note shall be applicable to
and binding upon each and every maker, holder, endorser,  surety, guarantor, and
all other persons who are or may become liable for the payment  hereof and their
respective successors or assigns.

                          SECURITIES PURCHASE AGREEMENT


          This Securities Purchase Agreement ("Agreement") is entered into as of
the  11th day of  October,  1996,  by and  between  Belcor  Inc.,  a  California
corporation  ("Buyer")  and Coastal  Capital  Partners,  L.P.  ("Seller"),  with
reference to the following facts:

                                    RECITALS

          A. Seller owns no less than  15,500,000  shares (the  "Shares") of the
Common Stock, $0.01 par value (the "Common Stock") of Rio Grande Mining Company,
a  Nevada  corporation  ("Rio").  Buyer  owns a ten  year  warrant  to  purchase
17,000,000  shares of the Common  Stock at a price of $0.24 per share.  Buyer is
familiar with the business of Rio.

          B. Of the  shares  of  Common  Stock  owned  by  Seller  approximately
6,395,340  shares  were  acquired  at $0.240 per share  cash,  with the  balance
acquired for  approximately  $0.181 per share cash.  Accordingly,  Seller has an
average cost price per share of approximately $0.219.

          C. The price at which Buyer's  common stock,  $0.01 par value ("Belcor
common  stock")  last  traded in the  public  market  in which it trades  was on
September  19,  1996,  was $0.0625 per share.  On September  27, 1996,  the last
available quoted bid and asked price was $0.05 and $0.07 per share.

          D. Rio's Common Stock is only  entitled to elect two  directors out of
Rio's five directors with the balance  elected by the holders of Rio's preferred
stock.  Accordingly,  the Shares do not directly or indirectly possess more than
fifty percent (50%) of the voting power of Rio.

          E. Buyer desires to purchase and Seller  desires to sell the Shares on
the terms and conditions set forth herein.

          THEREFORE,  in consideration of the foregoing  premises and the mutual
covenants set forth herein, Buyer and Seller hereby agree as follows:

          1.      Sale of Shares.

                  (a)  Sale  and  Purchase.  On the  terms  and  subject  to the
conditions set forth herein, Buyer hereby agrees to purchase,  and Seller hereby
agrees  to sell,  all of the  Shares  free  and  clear  of all  liens,  charges,
encumbrances and claims of any nature.

                  (b) Purchase  Price. As full payment for the transfer and sale
of the Shares to Buyer pursuant hereto, at the Closing (as hereinafter  defined)
Buyer shall issue to Seller 1.45 shares of Belcor common stock for each share of
the Shares, or an aggregate of 22,475,000 shares (the "Belcor shares").

          2. Purchase Price. The purchase price for the Red Hills Property shall

Closing occurs, Belcor and Rio Grande shall prorate taxes for such calendar year
or other applicable tax period based upon the most recent ascertainable assessed
values and tax rates using the tax bill for the previous  calendar year or other
applicable tax period. In the event that final bills are not available or cannot

availability of specific remedies.

          5.  Representations,   Warranties  and  Covenants  of  Belcor.  Belcor

                  5.4. It has knowledge and experience in financial and business
matters so as to be capable of evaluating  the merits and risks of an investment

REGISTRATION IS AVAILABLE.

          6. Further Assurances. Rio Grande and Belcor shall cooperate with each
other and execute and deliver such further  instruments  and documents as may be
necessary to more fully

                        BELCOR ANNOUNCES 80% OWNERSHIP OF
                            RIO GRANDE MINING COMPANY


Sonoma,  California - October 13, 1996. Belcor, Inc. (OTC-BLCR) ("Belcor") today
announced its Board of Directors,  on October 11, 1996, approved the acquisition
of  80.74%  of the  common  stock  of  Rio  Grande  Mining  Company  ("Rio"),  a
privately-held  company in the development  stage from Coastal Capital Partners,
L.P.  ("Coastal"),  a significant existing shareholder of Belcor. As a result of
the transaction,  Coastal  increased its ownership in Belcor from  approximately
16% to slightly over 80%. No management  changes are contemplated as a result of
the transaction.

Rio's  principal  asset is the  Shafter/Presidio  Project  located  in  Presidio
County, Texas. This project is a non-operating silver property in which over $16
million for  exploration  and  development  was invested by a prior owner in the
late 1970's and early 1980's. Rio's management estimates, based upon old reports
which have not been updated, that the Shafter/Presidio  Project contains over 30
million ounces of silver mineralized  material.  The old Presidio Mine, which is
included in the  Shafter/Presidio  property,  produced over 30 million ounces of
silver during the period 1883 through 1942.

Belcor acquired the Rio stock in the following manner:

          1)      Coastal contributed  15,500,000 of its Rio shares to Belcor in
                  exchange for 22,475,000 newly issued shares of Belcor based on
                  an  exchange  ratio of one  share of Rio for  1.45  shares  of
                  Belcor.

          2)      In exchange for 9,000,000 Rio common shares,  Belcor  canceled
                  its  outstanding   10-year   settlement  warrant  to  purchase
                  17,000,000 Rio shares at $.24 per share.

          3)      Belcor agreed to sell its copper mineral prospect known as the
                  Red Hills  property to Rio for  2,500,000  Rio shares.  At the
                  time of this  transaction,  the Red Hills property was carried
                  on  Belcor's  balance  sheet  at a value of  $116,000  and was
                  subject to a three-year option by Rio to purchase the property
                  for $600,000.

          4)      As a  result  of  the  transactions  described  above,  Belcor
                  acquired 27,000,000 Rio common shares, or approximately 80.74%
                  of the total Rio shares outstanding.

As of July 31, 1996, the date of Rio's latest  unaudited  financial  statements,
Rio had total assets of $2.26  million and total  stockholders'  equity of $1.19
million. For the nine months ended July 31, 1996 and from inception on September
28,  1992  through  July 31,  1996,  Rio  incurred  net losses of  $389,000  and
$1,011,000, respectively.

Belcor has  approximately $17 million in net operating losses for federal income
tax purposes.  As a result of the transaction  described above, Belcor's ability
to fully utilize such losses in the future may be significantly limited.
