              OTHER AGREEMENTS OF INDEPENDENCE AND ATLAS
              ------------------------------------------

               --------------------
deliver to Atlas originals and copies of all records, data and
information in its possession relating to the Properties, including,
without limitation, title and environmental data, and all maps,
surveys, technical reports, drill logs, and all metallurgical,
geological, geophysical, geochemical, permitting and other technical
data pertaining to the Properties in its possession; provided,
however, that Independence may retain copies of any or all of such
data; and provided, further, that if any such data includes
information other than with respect to the Properties the data may be
excerpted so as to provide only the information with respect to the
Properties.

                                  -3-

                         (Page 36 of 64 pages)<PAGE>
          3.2  Transfer of Permits.  For a period of sixty days
               -------------------
following Closing, Independence shall cooperate with Atlas to achieve,
to the extent reasonably possible, the assignment from Independence to
Atlas of any existing permits with respect to the Properties.

          3.3  Assumption of Obligations.  Upon Closing, Atlas shall
               -------------------------
assume Independence's obligations in connection with the Properties as
set forth in the Assumption Agreement, including obligations arising
under any permits issued by any federal, state or local authority, and
reclamation obligations, and Atlas will execute an assumption of such
obligations in the form of Exhibit B-5.

          3.4  NYSE Listing Requirements.  At the time of Closing,
               -------------------------
Atlas shall have complied with the requirements of the New York Stock
Exchange regarding the issuance by Atlas of the Shares, and the Shares
shall have been accepted for listing on such exchange.

          3.5  Reasonable Best Efforts; Further Assurances.  Subject
               -------------------------------------------
to the terms and conditions herein provided, each of the parties
hereto agrees to use its reasonable best efforts to take, or cause to
be taken, all action, and to do, or cause to be done, all things
reasonably necessary, proper or advisable under applicable laws and
regulations to consummate and make effective the transactions
contemplated by this Agreement.  Atlas and Independence will each use
their respective reasonable best efforts (without incurring any
extraordinary expense or payment to any third party in excess of
$2,500, or instituting litigation) to obtain consents of all third
parties and governmental bodies necessary to the consummation of the
transactions contemplated by this Agreement; provided, however, that
the foregoing expense limitation shall not apply to Atlas' costs in
acquiring any permits from Independence or to any action necessary or
advisable in connection with the issuance, listing or registration of
the Shares.  As used herein, "Further Assurances" shall mean any
deeds, assignments, consents, powers of attorney or other documents
which may be reasonably required to transfer ownership of the
Properties to Atlas, to confirm such ownership or facilitate effective
recordation thereof, or to put Atlas in actual possession and
operating control of the Properties.

          3.6  Access to Records Before Closing.  Prior to the Closing
               --------------------------------
Date, each of the parties agrees that it will give, or cause to be
given, to the other party and its representatives, during normal
business hours upon reasonable notice and at the other party's
expense, full and unrestricted access to its personnel, officers,
agents, employees, assets, properties, titles, contracts, books,
records, files and documents with respect to, in Independence's case,
the Properties, and in Atlas' case, Atlas (including financial, tax,
budget, projections, auditors' work papers and other information) and
to such party's personnel, as is reasonably necessary to allow such
other party to obtain such information as it shall desire, and to make
copies of all such materials.  All materials copied pursuant hereto
shall be maintained in confidence and all such copies shall be
returned to the party providing such materials if the transactions
contemplated hereunder fail to occur.

          3.7  Sales, Use, Transfer and Other Taxes.  Any sales and
               ------------------------------------
use taxes and real property transfer taxes imposed on the transfer of
the Properties by Independence to Atlas shall be paid by Atlas.  The
parties shall cooperate in obtaining any available 

                                  -4-

                         (Page 37 of 64 pages)<PAGE>
exemptions from sales, use and transfer taxes.  Prior to Closing,
Independence shall pay all expenses owed by it ordinarily paid in the
normal course of owning the Properties.  All claim transfer fees
assessed by the United States, Department of the Interior, Bureau of
Land Management (the "BLM"), and all expenses of recording instruments
of conveyance covering the Properties shall be paid by Atlas.

          3.8  BLM Exchange Property.  Independence has entered into
               ---------------------
an exchange agreement with the BLM to obtain fee title to the property
on which certain unpatented mining claims held by Independence are
located (the "Exchange Property").  The Exchange Property is more
particularly described in Exhibit A-2.

          Certain unpatented mining claims held by Independence and
comprising a portion of the Properties are located on and, in some
instances, extend across the exterior boundaries of the Exchange
Property (the "Exchange Claims").  The Exchange Claims are more
particularly described in Exhibit A-2.

          The conveyance of fee title to the Exchange Property to
Atlas is not a condition to Closing and the parties understand and
agree that the consummation of the contemplated exchange with the BLM
may occur after the Closing or not at all.  Independence is in no
manner obligated by this Agreement or otherwise to complete the
exchange and convey fee title to the Exchange Property to Atlas. 
However, if Independence completes the contemplated exchange with the
BLM and is conveyed fee title to the Exchange Property, for no
additional consideration, Independence shall convey to Atlas all of
its right, title and interest in and to the Exchange Property and the
fractions of the Exchange Claims that remain on the public lands
adjacent to the Exchange Property without any representations and
warranties of title, whatsoever.

          If Independence does not complete the contemplated exchange
with the BLM and/or is not conveyed fee title to the Exchange
Property, for any reason, including, without limitation, a
discretionary decision by Independence not to complete the exchange,
for no additional consideration, Independence shall convey to Atlas
all of its right, title and interest in and to the Exchange Claims. 
Real property transfer taxes associated with the foregoing conveyance
to Atlas shall be paid by Atlas; all costs and expenses to complete
the contemplated exchange with the BLM shall be paid by Independence. 
Notwithstanding anything in this Agreement that may appear to be to
the contrary, this Section 3.8 shall survive Closing until the
conveyance to Atlas of the Exchange Property and the fractions of the
Exchange Claims or the Exchange Claims, whichever is applicable. 
Unless otherwise agreed by Independence and Atlas, if the contemplated
exchange with the BLM is not completed on or before September 30,
1998, Independence shall convey to Atlas the Exchange Claims on or
before October 31, 1998.  Such conveyance will be made subject to the
same representations set forth in Section 4.1(g)(ii) hereof, which
representations shall survive for a period of 45 days from the date of
conveyance.

          From the Closing through conveyance to Atlas of the Exchange
Property or the Exchange Claims, whichever is applicable, Independence
grants to Atlas non-exclusive access to and the non-exclusive right to
use and occupy the surface and subsurface of the 

                                  -5-

                         (Page 38 of 64 pages)<PAGE>

               ------------------------

          6.3  Notification; Defense of Third-Party Claims.  An
               -------------------------------------------
indemnified person or entity shall give written notice to the
indemnifying person or entity promptly of any claim, suit, action, the
commencement of any proceeding or demand of which such indemnified
person or entity has received written notice from a third party (that
is, a party other than a party to this Agreement) and as to which such
indemnified person or entity believes it may be entitled to
indemnification or contribution hereunder or under this Agreement
(provided, that failure to give such notice which does not materially
disadvantage the indemnifying person or entity shall not relieve the
indemnifying person or entity from liability hereunder).  The
indemnifying person or entity will not settle or compromise any such
pending claim, action or suit, without (i) the prior written consent
of the indemnified person or entity, which consent shall not be
unreasonably withheld, and (ii) obtaining a release of the indemnified
person or entity from all liability in respect thereof.  The
indemnifying person or entity shall have the right to participate in
or assume and direct the defense at its own expense against any such
claim, suit or demand, in its name or in the name of the indemnified
person, as the case may be, and with counsel selected by the
indemnifying person; provided, that if (i) such claim, suit or demand
seeks an order, injunction or other equitable relief against the
indemnified person or entity or (ii) the indemnified person or entity
shall have reasonably concluded that there is a substantial conflict
of interest between the indemnifying person or entity and the indemni-
fied person or entity in the conduct of the defense of such claim,
suit or demand, then the indemnified party may employ separate counsel
and participate in and direct the defense of such claim, suit or
demand to the extent necessary to protect its interest and the
indemnifying person or entity will pay the reasonable fees and
disbursements of such separate counsel; provided, however, that the
indemnifying person or entity shall not be responsible for the fees
and disbursements of more than one separate counsel for all 

                                 -15-

                         (Page 48 of 64 pages)<PAGE>
indemnified persons or entities in any jurisdiction or in any single
proceeding.  Except as provided in the preceding sentence, after
notice from the indemnifying party of its election to assume the
defense thereof, the indemnifying person or entity shall not be liable
to the indemnified party for any legal or other expense incurred by
the indemnified party in connection with such claim.  Such assumed
defense shall be conducted expeditiously (but with regard to obtaining
the most favorable outcome reasonably likely under the circumstances,
taking into account costs) and the indemnified person or entity shall
be advised promptly of all significant developments.  The indemnified
person or entity shall have the right to participate fully in the
defense of any claim, suit or demand so assumed, with separate counsel
selected by it and at its own expense.  The indemnified person or
entity shall cooperate with the indemnifying person or entity, and
keep the indemnifying person or entity reasonably informed, in its
participation or defense of any such claim, suit or demand.

indemnifying person or entity promptly of any other claim it may have
for indemnification under this Article 6; provided, that failure to
give such notice which does not materially disadvantage the
indemnifying person or entity shall not relieve the indemnifying
person or entity from liability hereunder.  No indemnified person or
entity shall be entitled to make any claim for indemnification under
this Article 6 with respect to any breach of any particular
representation or warranty, after the date on which such representa-
tion and warranty ceases to survive pursuant to Article 9; provided,
                                                           --------
however, that, if prior to the close of business on the date any
- -------
representation or warranty ceases to survive, the indemnifying party
shall have received written notification of a claim for indemnity
hereunder containing the basis of any such claim and a brief statement
of the relevant facts to the extent known, and such claim shall not
have been finally resolved or disposed of on that date, such claim
shall continue as a basis for indemnity until finally resolved or
disposed of.

          6.5  Threshold.  No claim may be made for indemnification
               ---------
pursuant to this Article 6 with respect to any individual item of
liability or damage arising out of the breach or inaccuracy of any
representation or warranty unless such item or any series of items
arising out of the related or similar facts exceeds $1,000 and unless
and until the aggregate of all such liabilities and damages shall
exceed $50,000, in which case the indemnifying party shall then be
liable for all Losses, including the original $50,000.

and directors of each respective party and its Affiliates (as
hereinafter defined).

               --------------------------------------------
any officer or other managerial personnel of any of the parties has
actual Knowledge or notice of any facts or circumstances which would
contravene any of the representations, warranties and covenants set
forth herein, the parties hereto shall be entitled to rely upon the
representations, warranties, and covenants set forth herein.   Any
provision herein to the contrary notwithstanding, neither party shall
have any liability or obligation to the other for

                         (Page 49 of 64 pages)<PAGE>
any liability, claim, damage, loss or expense arising out of any fact,
inaccuracy or breach concerning any representation or warranty, if the
fact, inaccuracy or breach was actually known on the date hereof by an
officer or managerial employee of the party in whose favor the
representation or warranty runs.

                     REGISTRATION RIGHTS AGREEMENT
                     -----------------------------

          AGREEMENT made as of October 25, 1995 by and between Atlas
Corporation, a Delaware corporation ("Atlas"); and Independence Mining
Company Inc., a Delaware corporation ("Independence").


                              WITNESSETH:

          Atlas and Independence are parties to a Purchase and Sale
Agreement dated October 25, 1995 (the "Purchase Agreement").  In order
to induce Independence to consummate the transactions under the
Purchase Agreement, Atlas has agreed to provide the registration
rights set forth in this Agreement.  The execution and delivery of
this Agreement is a condition to the Closing under the Purchase
Agreement.  Certain capitalized terms used herein and not otherwise
defined are defined in Section 7 hereof.

          The parties hereto agree as follows:

          1.   SHELF REGISTRATION.  (a)  Atlas shall:  (i) as promptly
               ------------------
as possible following the date hereof file a Shelf Registration
Statement providing for resales of Registrable Securities by
Independence (the "Shelf Registration"); (ii) use its best efforts to
cause such Shelf Registration Statement to be declared effective as
promptly as is possible; and (iii) use its best efforts to keep the
Shelf Registration Statement continuously effective under the
Securities Act with respect to the Registrable Securities until
October 25, 1998, or, if sooner, until the Shares no longer constitute
Registrable Securities.  Atlas shall supplement or amend the Shelf
Registration Statement as necessary to comply with the Securities Act
and the rules and regulations thereunder, the rules, regulations or
instructions applicable to the registration form used by Atlas, or any
other law, rule or regulation applicable thereto.  Atlas shall pay all
Registration Expenses (as defined in Section 4) incurred in connection
with the Shelf Registration.

               (b)  In the event that Atlas becomes ineligible to file
a shelf registration statement on behalf of Independence, or the Shelf
Registration filed by Atlas on Independence's behalf becomes
ineffective as a means of registering the Registrable Securities, at
any time after October 25, 1996 and at Independence's request Atlas
shall register the sale of all or part of the Registrable Securities. 
Atlas shall be required to file only one registration statement to
effect the foregoing.

          2.   PIGGYBACK REGISTRATIONS.
               -----------------------

               (a)  RIGHT TO PIGGYBACK.  Whenever on or prior to
                    ------------------
October 25, 1998 Atlas proposes to register any of its securities
under the Securities Act to be issued in an underwritten public
offering by Atlas (other than pursuant to the Shelf Registration) and
the registration form to be used may be used for the registration of
Registrable Securities (a "Piggyback Registration"), Atlas will give
prompt written notice to Independence of its intention to effect such
a registration and will include in such registration all Registrable
Securities requested for inclusion therein by Independence.

                         (Page 57 of 64 pages)<PAGE>
               (b)  PIGGYBACK EXPENSES.  The Registration Expenses
                    ------------------
related to the Registrable Securities in any Piggyback Registration
will be paid by Atlas.

               (c)  PRIORITY ON REGISTRATIONS.  If the managing
                    -------------------------
underwriters of a Piggyback Registration advise Atlas in writing that
in their sole discretion the number of securities requested to be
included in such offering exceeds the number which can be sold in such
offering such that the offering will be materially adversely affected,
the number of securities to be offered will be reduced as recommended
in writing by the managing underwriters.  Atlas will include
securities in such registration according to the following priority: 
(i) the securities Atlas proposes to sell, and (ii) the Registrable
Securities requested to be included in such registration and other
securities requested to be included in such registration by holders of
Parity Registration Rights, allocated among the holders of Registrable
Securities and such other holders in proportion, as nearly as
practicable, to the respective number of shares of Common Stock
proposed to be sold in such offering by them.

               (d)  SELECTION OF UNDERWRITERS.  Atlas may select the
                    -------------------------
investment banker(s) and manager(s) for any offering pursuant to a
Piggyback Registration.

               (e)  OTHER REGISTRATIONS.  If Atlas has previously
                    -------------------
filed a registration statement with respect to Registrable Securities
pursuant to this Section 2, and if such previous registration has not
been withdrawn or abandoned, Atlas will not file or cause to be
effected any other registration of any of its equity securities or
securities convertible or exchangeable into or exercisable for its
equity securities under the Securities Act (except on Form S-4,
Form S-8 or any successor form), whether on its own behalf or at the
request of any holder or holders of such securities, until a period of
at least three months has elapsed from the effective date of such
previous registration, unless a shorter period of time is approved by
the holders of a majority of the Registrable Securities included in
such previous registration.

          3.   REGISTRATION PROCEDURES.  In connection with any
               -----------------------
registration pursuant to Section 1 hereof, whenever Independence has
requested that any Registrable Securities be registered pursuant to
this Agreement, Atlas will use its best efforts to effect the
registration and the sale of such Registrable Securities in accordance
with the intended method of disposition thereof and pursuant thereto
Atlas will as expeditiously as possible:

               (a)  furnish to each Seller of Registrable Securities
such number of copies of such registration statement, each amendment
and supplement thereto, the prospectus included in such registration
statement (including each preliminary prospectus) and such other
documents as such Seller may reasonably request in order to facilitate
the disposition of the Registrable Securities owned by it;

               (b)  use its best efforts to register or qualify such
Registrable Securities under such other securities or blue sky laws of
such jurisdictions as Independence reasonably requests and do any and
all other acts and things which may be reasonably necessary or
advisable to enable each Seller of Registrable Securities to
consummate the disposition in such jurisdictions of the Registrable
Securities owned by such Seller, provided 

                                  -2-

                         (Page 58 of 64 pages)<PAGE>
that Atlas will not be required to (i) qualify generally to do
business in any jurisdiction where it would not otherwise be required
to qualify but for this subsection, (ii) subject itself to taxation in
any such jurisdiction or (iii) consent to general service of process
in any such jurisdiction except to the extent required by applicable
law;

               (c)  notify each Seller of Registrable Securities, at
any time when a prospectus relating thereto is required to be
delivered under the Securities Act, of the happening of any event as a
result of which the prospectus included in such registration statement
contains an untrue statement of a material fact or omits any fact
necessary to make the statements therein not misleading, and, at the
request of any such Seller, Atlas will prepare a supplement or
amendment to such prospectus so that, as thereafter delivered to the
purchasers of such Registrable Securities, such prospectus will not
contain an  untrue statement of a material fact or omit to state any
fact necessary to make the statements therein not misleading;

               (d)  cause all such Registrable Securities to be listed
on each securities exchange on which similar securities issued by
Atlas are then listed;

               (e)  provide a transfer agent and registrar for all
such Registrable Securities;

               (f)  enter into such customary agreements (including
underwriting agreements in customary form) and take all such other
actions as Independence reasonably requests in order to expedite or
facilitate the disposition of such Registrable Securities; provided,
however, that in the event of any underwritten offering, Independence
will be responsible for the reasonable fees and disbursements of one
counsel to Atlas for such counsel's review of the underwriting
agreement to the extent such fees and disbursements exceed $2,500 up
to a maximum amount of $20,000;

               (g)  make available for inspection by any Seller of
Registrable Securities, any underwriter participating in any
disposition pursuant to such registration statement, and any attorney,
accountant or other agent retained by any such Seller or underwriter,
all financial and other records, pertinent corporate documents and
properties of Atlas, and cause Atlas' officers, directors, employees
and independent accountants to supply all information reasonably
requested by any such Seller, underwriter, attorney, accountant or
agent in connection with such registration statement; and

               (h)  obtain a cold comfort letter from Atlas'
independent public accountants in customary form and covering such
matters of the type customarily covered by cold comfort letters
(provided that such Registrable Securities constitute at least 10% of
the securities covered by such registration statement).

          Independence agrees that, upon receipt of any notice from
Atlas of the happening of any event of the kind described in
Section 3.1(c) hereof, Independence will forthwith discontinue
disposition of Registrable Securities pursuant to the registration
statement covering such Registrable Securities until Independence's
receipt of written notice 

                                  -3-

                         (Page 59 of 64 pages)<PAGE>
that sales may continue with the existing prospectus or the
supplemented or amended prospectus contemplated by Section 3(c)
hereof.  In the event Independence is not able to commence sales of
Shares pursuant to an effective registration statement not later than
60 days after the date of a notice pursuant to Section 3(c) (the
"Notice Date"), Atlas shall pay to Independence an amount per share
equal to the difference (but only if the price in (ii) is less than
the price in (i)), if any, between (i) the actual sales price
subsequently received from any sales by Independence during a number
of days following the date on which such sales become permissible
which is equal to the number of days over 60 during which such sales
were not allowed and (ii) the average of (A) the closing sales prices
on any national securities exchange or the NASDAQ National Market
System on which the Common Stock is listed or included, or (B) the
average of the bid and asked prices on NASDAQ if not so listed or
included for the days in excess of 60 from the Notice Date (such
average closing sales prices or average bid and asked price, as the
case may be, being referred to as the "Deemed Sales Price"), plus
interest calculated on the Deemed Sales Price from the 61st day after
the Notice Date to the date of any actual sale at the rate of 12% per
annum.

          4.   REGISTRATION EXPENSES.
               ---------------------

               (a)  All expenses incident to Atlas' performance of or
compliance with this Agreement, including, without limitation, all
registration and filing fees, fees and expenses of compliance with
securities or blue sky laws, printing expenses, messenger and delivery
expenses, and fees and disbursements of counsel for Atlas and all
independent certified public accountants, underwriters (excluding
discounts and commissions) and other Persons retained by Atlas (all
such expenses being herein called "Registration Expenses"), will be
borne as provided in this Agreement, except that Atlas will, in any
event, pay its internal expenses (including, without limitation, all
salaries and expenses of its officers and employees performing legal
or accounting duties), the expense of any annual audit or quarterly
review, the expense of any liability insurance and the expenses and
fees for listing the securities to be registered on each securities
exchange on which similar securities issued by Atlas are then listed.

               (b)  In connection with each registration of
Registrable Securities, Atlas will reimburse Independence for the
reasonable fees and disbursements of one counsel chosen by
Independence to the extent such fees and disbursements exceed $2,500
up to a maximum of $25,000.

          5.   INDEMNIFICATION.
               ---------------

               (a)  Atlas agrees to indemnify Independence, its
officers and directors and any person who controls Independence within
the meaning of the Securities Act against all losses, claims, damages,
liabilities and expenses (including legal fees and other expenses
incurred in defending any such claim or action) caused by any untrue
or alleged untrue statement of material fact contained in any
registration statement, prospectus or preliminary prospectus or any
amendment thereof or supplement thereto or any omission or alleged
omission of a material fact required to be stated therein or necessary
to make the statements therein not misleading; provided that Atlas
shall not be liable in any such case to 

                                  -4-

                         (Page 60 of 64 pages)<PAGE>
the extent that any such loss, claim, damage, liability (or action or
proceeding in respect thereof) or expense arises out of or is based
upon an untrue statement or alleged untrue statement or omission or
alleged omission made in such registration statement, any such
preliminary prospectus, prospectus, amendment or supplement in
reliance upon and in conformity with information furnished to Atlas in
writing by Independence specifically for use therein.  If the
indemnification provided for in this Section 5 is unavailable to or
insufficient to hold harmless Independence in respect of any losses,
claims, damages, or liabilities (or actions in respect thereof)
referred to therein, then Atlas shall contribute to the amount paid or
payable to Independence as a result of such losses, claims, damages,
or liabilities (or actions in respect thereof) in such proportion as
is appropriate to reflect the relative fault of Atlas and Independence
in connection with the statements or omissions which resulted in such
losses, claims, damages, or liabilities (or actions in respect
thereof), as well as any other relevant equitable considerations.  The
relative fault shall be determined by reference to, among other
things, whether the untrue or alleged untrue statement of a material
fact or the omission or alleged omission to state a material fact
relates to information supplied by Atlas or Independence and the
parties' relative intent, knowledge, access to information, and
opportunity to correct or prevent such statement or omission.

          (b)  Independence agrees to indemnify and hold Atlas and any
person who controls Atlas within the meaning of the Securities Act
harmless (in the same manner and to the same extent as set forth in
Section 5(a)) with respect to any statement or alleged statement in or
omission or alleged omission from such registration statement, any
preliminary prospectus, prospectus, or any amendment or supplement
thereto, if such statement or alleged statement or omission or alleged
omission was made in reliance upon and in conformity with written
information furnished to Atlas by Independence specifically for use
therein.

          6.   PARTICIPATION IN REGISTRATIONS.  No Person may
               ------------------------------
participate in any registration hereunder unless such Person:

               (a)  in the case of a registration which is
underwritten, agrees to sell such Person's Registrable Securities on
the basis provided in any underwriting arrangements approved by Atlas;

               (b)  as expeditiously as possible, notifies Atlas, at
any time when a prospectus relating to such Person's Registrable
Securities is required to be delivered under the Securities Act, of
the happening of any event involving such Person as a result of which
such prospectus contains an untrue statement of a material fact or
omits any fact necessary to make the statements therein not
misleading;

               (c)  complies with all reasonable requests made by
Atlas or its counsel with respect to the registration of such Person's
Registrable Securities, including, without limitation, providing
access to all relevant books and records; and

               (d)  completes, executes and delivers all
questionnaires, powers of attorney, indemnities, underwriting
agreements and other usual and customary documents 

                                  -5-

necessary or appropriate with respect to the offering of such Person's
Registrable Securities, and in the case of a registration which is
underwritten, necessary or appropriate under the terms of such
underwriting arrangements.

               (a)  "Affiliate" shall have the meaning ascribed to it
                     ---------
in Rule 12b-2 under the Securities Exchange Act of 1934, as amended
(the "Exchange Act"), and the rules and regulations of the SEC as in
effect on the date hereof.

               (b)  "Parity Registration Rights" means the right to
                     --------------------------

instrument granting such rights, are on a parity with the rights of
Independence under this Agreement.

               (c)  "Person" shall mean any individual, firm,
                     ------

comprised of any Person and any other Person with whom such Person or

understanding, directly or indirectly, for the purpose of acquiring,
holding, voting or disposing of any Common Stock.
