on a basis comparable to Form S-3), the Company will so notify the Selling
Stockholders and the Permitted Transferees in writing and the use of the Shelf
Registration Statement and the related prospectus will be automatically
suspended (a “Suspension”) until such time as the Company eligible to
use Form S-3 (or such successor form). 
The Company will not be required to register the Registrable Securities
on any other form promulgated by the Commission that does not permit
incorporation by reference of Exchange Act-filed reports and documents on a
basis comparable to Form S-3.  In
the event of any Suspension, the Company will use its reasonable best efforts
to again become eligible to use Form S-3 (or such successor form) as soon
as reasonably practicable and will promptly notify the Selling Stockholders and
the Permitted Transferees when it does become so eligible; provided  that,
for the avoidance of doubt, the Company acknowledges that use of the Shelf
Registration Statement and the related prospectus shall be automatically
reinstated without further action by any party at such time as the Company is
again eligible to use Form S-3 (or such successor form).

(d)                                 Black-Out Periods.  Notwithstanding anything to the contrary
contained in this Agreement, but without limiting the provisions of paragraph (c)
of this Section 2, the Company may temporarily suspend the use of
the Shelf Registration Statement and the related prospectus, by giving written
notice thereof to the Selling Stockholders and the Permitted Transferees, for
one period during any 360-day period not to exceed thirty (30) days in the
aggregate (the “Black-Out Period”) if, in the good faith opinion of the
Company’s Board of Directors, (i) the Shelf Registration Statement is not
usable because a prospectus is required, pursuant to Rule 3-05 and Article 11
of the Regulation S-X (or any successor provisions), to include financial
statements in respect of businesses acquired or to be acquired and pro forma
financial statements and such financial statements are not readily available or
(ii) (x) the Company’s ability to complete a pending or planned material
debt or equity financing, licensing arrangement, joint venture, acquisition or
disposition of assets or stock, merger or other material corporate transaction
could reasonably be expected to be materially and adversely affected by any
disclosure of such transaction required as a result of the continued
effectiveness of the Shelf Registration Statement or (y) the continued
effectiveness of the Shelf Registration Statement would require the Company to
make public disclosure of information the public disclosure of which is not
otherwise required and could reasonably be expected to have a material adverse
effect on the Company.  The Company will
not be required to specify in the written notice to the Selling Stockholders
and the Permitted Transferees the nature of the event giving rise to any
Black-Out Period.  In the event of any
Black-Out Period, the Company will use its reasonable best efforts to cause the
use of the Shelf Registration Statement and the related prospectus so suspended
to be resumed as promptly as practicable after delivery of the notice of such
Black-Out Period to the Selling Stockholders and the Permitted Transferees and
shall promptly notify the Selling Stockholders and the Permitted Transferees of
such resumption; provided  that, for the avoidance of doubt, the
Company acknowledges that use of the Shelf Registration Statement and the
related prospectus shall be automatically reinstated without further action by
any party at the expiration of the Black-Out Period.

 

3.                                       Requests for
Public Offering; Offerings by Selling Stockholders.

 

(a)                                  Initial Six-Month

during the Initial Six-Month Period, any one or more Selling Stockholder[s] and/or
Permitted Transferee[s] may request that the Company use its reasonable best
efforts to effect one or more Underwritten Public Offerings, which may include
customary “road show” presentations and all other customary selling efforts,
all as the applicable underwriters shall reasonably request (each such
requested Underwritten Public Offering, a “Requested Public Offering”)
in accordance with Section 5. 
During the SPCC Sponsorship Period, Registrable Securities owned by the
Selling Stockholders and Permitted Transferees may only be sold in Requested
Public Offerings that are sponsored by the Company.  Except as provided in the immediately
following sentence, any such request[s] for Requested Public Offerings shall be
in writing and delivered by the requesting Selling Stockholders and/or
Permitted Transferees, as applicable, to, or received by, the Company, and each
of the other Selling Stockholders and Permitted Transferees as applicable, in
accordance with Section 10(a). 
The Selling Stockholders and Permitted Transferees shall be deemed to
have made a request for a Requested Public Offering at the Effectiveness Date; provided that (x) the Company shall have notified such
Selling Stockholders and Permitted Transferees of the anticipated Effectiveness
Date at least 5 Business Days prior to the time that the Company submits a
request to accelerate effectiveness of the Shelf Registration Statement to the
Commission and neither Cerro nor PD

 

7

 

notify the Company in
writing prior to the Effectiveness Date that they object to the commencement of
a Requested Public Offering on the Effectiveness Date.

 

(b)                                 Requested Public

and the limitations set forth in Section 3(c), in the case
of each request for a Requested Public Offering made during the Initial
Six-Month Period, the Company shall:

 

(i)                                     use
its reasonable best efforts to prepare and file with the Commission within (x) 20
Business Days (in the case of the first Requested Public Offering) and (y)
within 8 Business Days (in the case of any subsequent Requested Public
Offering) a prospectus supplement or post-effective amendment to the Shelf
Registration Statement, as necessary, to permit the consummation of the
applicable Requested Public Offering; and

 

(ii)                                  permit
any other Selling Stockholder and any Permitted Transferee to participate in
such Requested Public Offering (subject to the proviso at the end of this
paragraph (b)) if within five Business Days of receipt by all of the Company,
Cerro and PD of a request for a Requested Public Offering from any one or more
Selling Stockholder[s] and/or Permitted Transferee[s], such other Selling
Stockholder and/or Permitted Transferee delivers to the Company and each other
Selling Stockholder and Permitted Transferee written notice in accordance with Section 10(a)
that it desires to sell its Registrable Securities in such Requested Public
Offering;

 

provided
that, notwithstanding the foregoing, the number of Registrable
Securities to be sold by the Selling Stockholders and any Permitted Transferees
in connection with a Requested Public Offering shall be determined by the
Managing Underwriter (in consultation with the Company, Cerro and PD) to be the
maximum number of Registrable Securities that may be sold, including in
connection with the exercise by the underwriters of any related over-allotment
options, without causing a significant disruption in the market for shares of
the Common Stock.  Notwithstanding
anything in this clause (b) to the contrary, the number of
Registrable Securities to be sold in any such Requested Public Offering shall
not be less than 20,000,000, or such lesser amount as the Managing Underwriter
determines can be sold as provided in the previous sentence (such number of
Registrable Securities to be adjusted proportionately to reflect any stock
dividend, stock split, reclassification, reorganization, recapitalization,
distribution or other similar event in respect of the Shares).

 

(c)                                  Limitations on Requested
Public Offerings. 
Notwithstanding anything herein to the contrary, the Company shall not
be required to honor a request for a Requested Public Offering by any one or
more Selling Stockholder(s) or Permitted Transferee(s) if:

 

(i)                                     such
request for a Requested Public Offering is received by the Company after the
expiration of the Initial Six-Month Period;

 

(ii)                                  the
Registrable Securities requested by the Selling Stockholders and the Permitted

not constitute at least 10,000,000 Shares (such number of Registrable
Securities to be adjusted proportionately to reflect any stock dividend, stock
split, reclassification,

 

8

 

reorganization, recapitalization, distribution or other similar event
in respect of the Shares); provided, however, that, to the extent
that the aggregate number of remaining Registrable Securities is less than
10,000,000 at the time a Requested Public Offering is requested, the Company
shall be required to honor such request for a Requested Public Offering; provided
further that all such remaining Registrable Securities then held by (x) the
Cerro Entities (in the case of a request by all or any of them) or (y) the PD
Entities (in the case of a request by all or any of them) are requested to be
sold in connection with such Requested Public Offering; or

 

(iii)                               such
request is received by the Company at any time during the Initial Six-Month
Period that a Requested Public Offering is in progress, regardless of whether
the Selling Stockholder or Permitted Transferee making such request exercised its
rights under this Agreement to participate in such Requested Public Offering.

 

(d)                                 Sales by Cerro
Entities.  During the Second
Six-Month Period, each of the Cerro Entities shall have the right to effect
sales of Registrable Securities included in the Shelf Registration Statement in
any manner contemplated in the Plan of Distribution; provided, however,
that the Cerro Entities may not sell more than 1,000,000 Registrable Securities
in the aggregate per calendar month (such 1,000,000 to be adjusted
proportionately to reflect any stock dividend, stock split, reclassification,
reorganization, recapitalization, distribution or other similar event in
respect of the Shares).  If the Cerro
Entities desire to sell more than 1,000,000 Registrable Securities in the
aggregate in any calendar month pursuant to this Section 3(d), Cerro
shall determine as between the Cerro Entities which of such Registrable
Securities may be sold.  The Company
shall not have any obligation to enter into any underwriting agreements or to
arrange, prepare for, or participate in, any “road show” presentations or any
other selling efforts in connection with, or any obligation otherwise with
respect to, any offerings of its securities that may be effected by any Cerro
Entity following the expiration of the Initial Six-Month Period.

 

(e)                                  Sales by PD

Six-Month Period, each of the PD Entities shall have the right to effect sales
of Registrable Securities included in the Shelf Registration Statement in any
manner contemplated in the Plan of Distribution; provided, however,
that the PD Entities may not sell more than 1,000,000 Registrable Securities in
the aggregate per calendar month (such 1,000,000 to be adjusted proportionately
to reflect any stock dividend, stock split, reclassification, reorganization,
recapitalization, distribution or other similar event in respect of the
Shares).  If the PD Entities desire to
sell more than 1,000,000 Registrable Securities in the aggregate in any
calendar month pursuant to this Section 3(e), PD shall determine as
between the PD Entities which of such Registrable Securities may be sold.  The Company shall not have any obligation to
enter into any underwriting agreements or to arrange, prepare for, or
participate in, any “road show” presentations or any other selling efforts in
connection with, or any obligation otherwise with respect to, any offerings of
its securities that may be effected by any PD Entity following the expiration
of the Initial Six-Month Period.

 

(f)                                    Priority in
Cutback Registrations.  With
respect to any Requested Public Offering effected by the Company during the Initial
Six-Month Period, if such Requested Public Offering becomes a Cutback
Registration, the Company will include in any such Requested Public Offering a
number of Registrable Securities not less than that which the Managing
Underwriter determines is the maximum number of Registrable Securities that may
be sold in

 

9

 

such Requested Public
Offering without causing a significant disruption in the market for shares of
the Common Stock, which Registrable Securities shall be allocated among the Cerro
Entities and the PD Entities that have elected to participate in such Requested
Public Offering pro rata on the basis of the
number of Registrable Securities each such Cerro Entity and/or PD Entity owns
on the date that the Managing Underwriter makes such determination.  Following the determination of any such pro rata allocation, each of Cerro and PD shall have the
right to specify what portion of the aggregate Registrable Securities so
allocated to the participating Cerro Entities (in the case of Cerro) and the
participating PD Entities (in the case of PD) may be sold by each such
participating Cerro Entity or PD Entity, as applicable, in connection with such
Cutback Registration.

three days before filing with the Commission, provide to each Selling
Stockholder and Permitted Transferee drafts of each document to be filed in
connection with the Shelf Registration Statement substantially in the form in

of any Requested Public Offering being effected pursuant to the Shelf
Registration Statement and Section 3, the Company shall select the
Managing Underwriter and any other underwriter or underwriters with respect to
such offerings, which underwriter or underwriters shall be reasonably
satisfactory to PD and Cerro.  Such
underwriter or underwriters will be instructed to effect as broad a

into an underwriting agreement in customary form with such underwriter or
underwriters, which shall be reasonably satisfactory to the Company and the
Selling Stockholders and any Permitted Transferees participating in such
Requested Public Offering, and shall include, among other provisions,
indemnities to the effect and to the extent provided in Section 7.  At the request of the Company, any Selling
Stockholder or Permitted

 

15

Public Offering shall be parties to such underwriting agreements and the
Selling Stockholders and any Permitted Transferees participating in the
applicable Requested Public Offering, may, at their option, require that any or
all of the representations and warranties by, and the other agreements on the
part of, the Company to and for the benefit of such underwriters pursuant to
such underwriting agreements also be made to and for the benefit of the Selling
Stockholders and the Permitted Transferees participating in such Requested
Public Offering and that any or all of the conditions precedent to the
obligations of such underwriters under such underwriting agreements also be
conditions precedent to the obligations of the Selling Stockholders and the
Permitted Transferees participating in such Requested Public Offering.  Notwithstanding anything to the contrary
herein, neither the Selling Stockholders nor any Permitted Transferees
participating in the applicable Requested Public Offering shall be required to
make any representations or warranties to or agreements with the Company or the
underwriters other than representations, warranties or agreements regarding such
Selling Stockholder or such Permitted Transferee, respectively, its ownership
of the Registrable Securities being offered on its behalf, its intended method
of distribution of such Registrable Securities and any other representation
required by law.  In the case of a
Requested Public Offering, immediately prior to the signing of the applicable
underwriting agreement, the Managing Underwriter shall notify the Company, each
Selling Stockholder and each Permitted Transferee participating in such
Requested Public Offering of the price, underwriting discount and other
financial terms at which it expects the applicable Registrable Securities to be
sold.  The price, underwriting discount
and other financial terms related to the sale of the Registrable Securities in
the related underwriting agreement shall be subject to the reasonable approval
of each Selling Stockholder and each Permitted Transferee participating in such
Requested Public Offering.  If one or
more Selling Stockholders or Permitted Transferees participating in such
Requested Public Offering does not provide such approval, the Registrable
Securities of such non-approving Selling Stockholders and Permitted Transferees
shall not be included in such Requested Public Offering and in such case if the
Company had previously implemented a pro rata
reduction in the number of Registrable Securities that the Selling Stockholders
and Permitted Transferees providing such approval may sell in such Requested
Public Offering, the Company shall implement a corresponding pro rata increase in the number of Registrable Securities
that the Selling Stockholders and Permitted Transferees providing such approval
shall sell in such Requested Public Offering.

 

(b)  Over-allotment
Options.  If and to the extent that
(i) the underwriting agreement executed in connection with a Requested Public
Offering as provided in Section 5(a) grants the applicable
underwriters an over-allotment option, (ii) the underwriters elect to exercise
such over-allotment option and (iii) the Selling Stockholders and/or any
Permitted Transferees participating in such Requested Public Offering at the
time of such exercise(s) still hold Registrable Securities, the Company, the
Selling Stockholders and any Permitted Transferees hereby agree that the
obligations, if any, of the Company, the Selling Stockholders and Permitted
Transferees to sell additional Shares pursuant to such over-allotment option
shall be satisfied first from the Registrable Securities still held by the
Selling Stockholders and any Permitted Transferees at the time of such
exercise(s), with the remainder, if any, to be covered by the Company.

6.                                       Lockup
Agreements.

 

(a)  By the Selling Stockholders and Permitted
Transferees. 
(i)  Notwithstanding anything in
this Agreement to the contrary, during the SPCC Sponsorship Period, the Selling
Stockholders and the Permitted Transferees shall not sell or transfer any Registrable
Securities other than through a Requested Public Offering sponsored by the
Company and effected pursuant to this Agreement; provided, however,
that each of the Selling Stockholders shall be permitted to dividend or
otherwise transfer all or any portion of its Shares to not more than a total of
seven (7) permitted transferees (the “Permitted Transferees”) to be
selected, in the case of Cerro or SPC, exclusively from among Cerro’s parent
corporation, SPC, and Cerro’s parent corporation’s trust shareholders and/or
beneficiaries and any Person owned or controlled by such trust shareholders
and/or beneficiaries, and in the case of PDOCC or Climax, exclusively from
among the Affiliates of PDOCC and Climax; provided, further, that,
in advance of effecting any such dividend or transfer, the Selling Stockholders
shall provide written notice to the Company of the proposed Permitted
Transferee, notice information for the proposed Permitted Transferee, the date
of transfer and the number of Shares to be transferred; provided, further,
that any such Permitted Transferee shall first execute and deliver to the
Company one or more counterparts to this Agreement agreeing to be bound by its
terms.

 

(ii)  Notwithstanding anything in this Agreement to
the contrary, during the period beginning on the Effective Time and ending on
the Termination Date, none of the Selling Stockholders or the Permitted
Transferees, if any, shall, without the prior written consent of AMC and the
Company, which consent shall not be unreasonably withheld, knowingly sell all
or any portion of its shares of Common Stock to any strategic buyers or
competitors of the Company other than through a Public Offering effected
pursuant to this Agreement.

 

(iii)  If and to
the extent requested by the Managing Underwriter (or, in the case of a non-Underwritten
Public Offering, the Company), the Selling Stockholders and any Permitted
Transferees agree, to the extent that the Selling Stockholders and such
Permitted Transferees are timely notified by the Managing Underwriter (or the
Company), not to effect any public sale or distribution (including a sale under
Rule 144) of Registrable Securities, or any securities convertible into or
exchangeable or exercisable for such securities, during the 10 days prior
to and the 60 days after the consummation or termination of such Public
Offering or non-Underwritten Public Offering (or for such longer period of time
not to exceed 90 days as is sufficient and appropriate, in the opinion of
the Managing Underwriter (or, in the case of a non-Underwritten Public Offering,
the Company), in order to complete the sale and distribution of the securities
included in such Public Offering), except as part of such Public Offering,
whether or not the Selling Stockholders or such Permitted Transferees
participate in such Public Offering.

 

(b)                                 By
the Company.  (i)  To the extent the Company is timely notified
by the Managing Underwriter, the Selling Stockholders or any Permitted
Transferee, the Company agrees and, to the extent requested by the Managing
Underwriter, shall use its reasonable best efforts to cause its executive
officers and directors to agree, not to effect any public sale or distribution
of the Company’s equity securities, or any securities convertible into or
exchangeable or exercisable for such securities, during the 10 days prior
to and the 60 days after the consummation or termination of a Requested
Public Offering (or for such longer period of time not to exceed 90 days as is
sufficient and appropriate, in the opinion of the Managing Underwriter), except
as part of such underwritten registration and except pursuant to

 

17

 

registrations on
Form S-4 or in connection with any employee benefit plan or pursuant to
the exercise of outstanding options, warrants or similar rights; and

 

(ii)  The
Company agrees not to conduct during the SPCC Sponsorship Period a primary
offering of any equity securities or any securities convertible into or
exchangeable or exercisable for such securities; provided, however,
that the Company shall have the right during such period to issue shares of
Common Stock or equity securities or any securities convertible into or
exchangeable for such securities, including Common Stock issuable upon the sale
or conversion of the Class A Common Stock, in connection with acquisitions,
mergers, business combinations, benefit plans and other similar transactions,
as the case may be.

 

(c)                                  By
AMC.  AMC agrees not to sell,
and will use its reasonable best efforts to prevent any of its Affiliates from
selling, during the SPCC Sponsorship Period any shares of Common Stock or other
equity securities or any securities convertible into or exchangeable or
exercisable for such securities, including Common Stock issuable upon the sale
or conversion of the Class A Common Stock.

 

7.                                       Indemnification.

 

(a)                                  Indemnification by
the Company.  The Company
shall, to the full extent permitted by law, indemnify and hold harmless each
seller of Registrable Securities included in the Shelf Registration Statement,
its directors, officers, employees, advisors and agents (collectively, “Representatives”),
and each other Person, if any, who controls any such seller within the meaning
of the Securities Act or the Exchange Act and each such controlling Person’s
Representatives (collectively, the “Company Indemnitees”), against any
losses, claims, damages, expenses or liabilities, joint or several (together, “Losses”),
to which such Company Indemnitees may become subject under the Securities Act
or otherwise, insofar as such Losses (or actions or proceedings in respect
thereof) arise out of or are based upon any untrue statement or alleged untrue
statement of any material fact contained in the Shelf Registration Statement,
any preliminary prospectus, final prospectus or summary prospectus contained
therein, or any amendment or supplement thereto, including all documents
incorporated therein by reference, or any omission or alleged omission to state
therein a material fact required to be stated therein or necessary to make the
statements therein (in the case of a prospectus, in the light of the
circumstances under which they were made) not misleading and such untrue
statement or alleged untrue statement or omission or alleged omission was not
corrected in a subsequent amendment or supplement prior to or concurrently with
the sale of Registrable Securities to the Person asserting such Loss, and the
Company will reimburse such Company Indemnitees for any legal or any other
expenses reasonably incurred by them in connection with investigating or defending
any such Loss (or action or proceeding in respect thereof); provided
that the Company shall not be liable to a Company Indemnitee in any such case
to the extent that any such Loss (or action or proceeding in respect thereof)
arises out of or is based upon (x) an untrue statement or alleged untrue
statement or omission or alleged omission made in any such registration
statement, preliminary prospectus, final prospectus, summary prospectus,
amendment or supplement in reliance upon and in conformity with written
information furnished by the related seller to the Company expressly for use in
the preparation thereof or (y) such related seller’s failure to send or
give a copy of the final prospectus to the Persons who assert an untrue
statement or alleged untrue statement or omission or alleged omission at or
prior to the written confirmation of the

 

18

 

sale of Registrable
Securities to such Person if such statement or omission was corrected in such
final prospectus.  The Company shall also
indemnify each other Person who participates (including as an underwriter) in
the offering or sale of Registrable Securities, their officers and directors
and each other Person, if any, who controls any such participating Person
within the meaning of the Securities Act or the Exchange Act to the same extent
as provided above with respect to Company Indemnitees.  The indemnity in this paragraph (a) of Section 7
shall be in addition to any liability the Company may otherwise have.

 

(b)                                 Indemnification by
the Sellers.  Each holder of
Registrable Securities which are included or are to be included in the Shelf
Registration Statement, as a condition to including Registrable Securities in
such registration statement, shall, severally and not jointly, to the full
extent permitted by law, indemnify and hold harmless the Company, its Representatives,
and each other Person, if any, who controls the Company within the meaning of
the Securities Act or the Exchange Act and each such controlling Person’s
Representatives (collectively, the “Seller Indemnitees”) against any
Losses to which the Seller Indemnitees may become subject under the Securities
Act or otherwise, insofar as such Losses (or actions or proceedings in respect
thereof) arise out of or are based upon any untrue statement or alleged untrue
statement of any material fact contained in any such registration statement,
any preliminary prospectus, final prospectus or summary prospectus contained
therein, or any amendment or supplement thereto, or any omission or alleged
omission to state therein a material fact required to be stated therein or
necessary to make the statements therein (in the case of a prospectus, in the
light of the circumstances under which they were made) not misleading, if such
untrue statement or alleged untrue statement or omission or alleged omission
was made in reliance upon and in conformity with written information furnished
to the Company by such holder specifically stating that it is for use in the
preparation of such registration statement, preliminary prospectus, final
prospectus, summary prospectus, amendment or supplement and was not corrected
in a subsequent writing prior to or concurrently with the sale of Registrable
Securities to the Person asserting such Loss; provided, however,
that the aggregate amount which may be recovered from any holder of Registrable
Securities pursuant to the indemnification provided for in this Section 7(b)
in connection with any registration and sale of Registrable Securities shall be
limited to the total proceeds received by such holder from the sale of such
Registrable Securities.  Such holders
shall also indemnify each other Person who participates (including as an
underwriter) in the offering or sale of Registrable Securities, their officers
and directors and each other Person, if any, who controls any such
participating Person within the meaning of the Securities Act or the Exchange
Act to the same extent as provided above with respect to the Seller Indemnitees.  The indemnity in this paragraph (b) of Section 7
shall be in addition to any liability such holder may otherwise have.

 

(c)                                  Notices of Claims,
etc.  Promptly after receipt
by an Indemnified Party of notice of the commencement of any action or
proceeding involving a claim referred to in the preceding paragraph (a)
or (b) of this Section 7, such Indemnified Party will, if a
claim in respect thereof is to be made against an Indemnifying Party pursuant
to such paragraphs, give written notice to the latter of the commencement of
such action, provided that the failure of any Indemnified Party to give
notice as provided herein shall not relieve the Indemnifying Party of its
obligations under the preceding paragraphs of this Section 7,
except to the extent that the Indemnifying Party is actually prejudiced by such
failure to give notice.  In case any such
action is brought against an Indemnified Party, the Indemnifying Party shall be
entitled to participate in

 

19

 

and to assume the defense
thereof, jointly with any other Indemnifying Party similarly notified to the
extent that it may wish, with counsel reasonably satisfactory to such
Indemnified Party, and after notice from the Indemnifying Party to such
Indemnified Party of its election so to assume the defense thereof, the
Indemnifying Party shall not be liable to such Indemnified Party for any legal
or other expenses subsequently incurred by the latter in connection with the
defense thereof other than reasonable costs of investigation; provided
that the Indemnified Party or Indemnified Parties shall have the right to
employ one counsel to represent it or them if (A) in the reasonable judgment of
the Indemnified Party or Indemnified Parties, it is advisable for it or them to
be represented by separate counsel by reason of having legal defenses which are
different from or in addition to those available to the Indemnifying Party or
(B) the named parties to any such action include both the Indemnifying Party
and the Indemnified Party and the Indemnified Party shall have been advised by
its counsel that there may be a conflict of interest between the Indemnified
Party and the Indemnifying Party in the conduct of the defense of such action,
and in any of the foregoing events the reasonable fees and expenses of such one
counsel shall be paid by the Indemnifying Party.  If the Indemnifying Party is not entitled to,
or elects not to, assume the defense of a claim, it will not be obligated to
pay the fees and expenses of more than one counsel for the Indemnified Parties
with respect to such claim, unless in the reasonable judgment of any
Indemnified Party a conflict of interest may exist between such Indemnified
Party and any other Indemnified Parties with respect to such claim, in which event
the Indemnifying Party shall be obligated to pay the fees and expenses of such
additional counsel for the Indemnified Parties or counsels.  No Indemnifying Party shall consent to entry
of any judgment or enter into any settlement without the consent of the
Indemnified Party which (i) does not include as an unconditional term thereof
the giving by the claimant or plaintiff to such Indemnified Party of a release
from all liability in respect to such claim or litigation or (ii) includes any
admission of wrongdoing on the part of the Indemnified Party.

 

(d)                                 Contribution.  If the indemnity and reimbursement obligation
provided for in any paragraph of this Section 7 is unavailable or
insufficient to hold harmless an Indemnified Party in respect of any Losses (or
actions or proceedings in respect thereof) referred to therein, then the
Indemnifying Party shall contribute to the amount paid or payable by the
Indemnified Party as a result of such Losses (or actions or proceedings in
respect thereof) in such proportion as is appropriate to reflect the relative
fault of the Indemnifying Party on the one hand and the Indemnified Party on
the other hand in connection with untrue statements or alleged untrue
statements or omissions or alleged omissions which resulted in such Losses, 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 the Indemnifying Party or the
Indemnified Party and the parties’ relative intent, knowledge, access to
information and opportunity to correct or prevent such untrue statement or
omission.  The parties hereto agree that
it would not be just and equitable if contributions pursuant to this paragraph
were to be determined by pro rata
allocation or by any other method of allocation which does not take account of
the equitable considerations referred to in the first sentence of this
paragraph.  The amount paid by an
Indemnified Party as a result of the Losses referred to in the first sentence
of this paragraph shall be deemed to include any legal and other expenses
reasonably incurred by such Indemnified Party in connection with investigating
or defending any Loss which is the subject of this paragraph.

 

20

 

No Indemnified Party guilty of fraudulent
misrepresentation (within the meaning of Section 11(f) of the Securities
Act) shall be entitled to contribution from the Indemnifying Party if the
Indemnifying Party was not guilty of such fraudulent misrepresentation.

 

Notwithstanding the provisions of this Section 7(d),
no Indemnifying Party (other than the Company) shall be required to contribute
any amount which is in excess of the amount by which the total proceeds
received by such Indemnifying Party from the sale of Registrable Securities
(net of all underwriting discounts and commissions) exceeds the amount of any
damages that such Indemnifying Party has otherwise been required to pay by
reason of such untrue or alleged untrue statement or omission or alleged
omission.

 

(e)                                  Other
Indemnification. 
Indemnification similar to that specified in the preceding paragraphs of
this Section 7 (with appropriate modifications) shall be given by
the Company and each seller of Registrable Securities with respect to any
required registration or other qualification of securities under any federal or
state law or regulation of any governmental authority other than the Securities
Act.

 

(f)                                    Other
Rights to Indemnification or Contribution. 
The provisions of this Section 7 shall be in addition to any
other rights to indemnification or contribution which an Indemnified Party may
have pursuant to law, equity, contract or otherwise.

 

8.                                       Termination.  This Agreement and the rights and obligations
of the parties hereto (other than Section 2(b), Section 3(g)(ii),
Section 7 and this Section 8, which shall survive any
termination of this Agreement) shall automatically terminate, and shall cease
to be of any further force or effect on the earlier of (i) the first day
after the expiration of the Second Six-Month Period and (ii) the date on
which all of the Registrable Securities owned by the Selling Stockholders and
any Permitted Transferees on the date hereof have been disposed of in
accordance with the Shelf Registration Statement (such earlier date, the “Termination
Date”); provided, however, that in no event shall the Termination Date be
later than the date that is eighteen (18) months from the date of this
Agreement.

 

9.                                       Conditions to
Obligations of Company and AMC. 
The parties to this Agreement (including any Permitted Transferees)
hereby agree that the obligations of the Company and AMC under this Agreement are
subject to the condition that the Effective Time shall have occurred and, with
respect to the obligations of the Company and AMC under this Agreement to each
Selling Stockholder and Permitted Transferee, to the further conditions that each
such Selling Stockholder or Permitted Transferee, as the case may be, shall
have taken all steps required to be taken by it under Section 4.9(c) of
the Restated Certificate of Incorporation to effect the voluntary conversion of
all shares of Class A Common Stock owned by each such Selling Stockholder or
Permitted Transferee, as the case may be.

 

10.                                 Miscellaneous.

address, facsimile number or other information for the purpose of notices to
that party by giving notice specifying such change to the other parties hereto.

 

(b)                                 Entire Agreement.  This Agreement sets forth the entire
understanding of the parties hereto with regard to the subject matter hereof
and supersedes all prior discussions and agreements between the parties with respect
to the subject matter hereof, including, without limitation, the Cerro Letter
Agreement and the PD Letter Agreement.

 

(c)                                  Amendment.  This Agreement may be amended, supplemented
or modified only by a written instrument (which may be executed in any number
of counterparts) duly executed by or on behalf of each of the parties hereto.

 

(d)                                 Waiver.  Subject to paragraph (e) of this Section 10,
any term or condition of this Agreement may be waived at any time by the party
that is entitled to the benefit thereof, but no such waiver shall be effective
unless set forth in a written instrument duly executed by or on behalf of the
party waiving such term or condition.  No
waiver by any party of any term or condition of this Agreement, in any one or
more instances, shall be deemed to be or construed as a waiver of the same term
or condition of this Agreement on any future occasion.

 

(e)                                  Consents and
Waivers.  Any consent of a
party hereto pursuant to this Agreement, and any waiver by a party hereto of
any provision of this Agreement, shall be in writing (which may be executed in
any number of counterparts), and any such consent or waiver so given or taken
will be binding on such party.

 

(f)                                    Third Party
Beneficiary.  The terms and
provisions of this Agreement are intended solely for the benefit of each party
hereto, their respective successors or permitted assigns and any other holder
of Registrable Securities, and it is not the intention of the parties to

 

23

 

confer third-party
beneficiary rights upon any other Person other than any Person entitled to
indemnity under Section 7.

 

(g)                                 Comparable
Agreements.  The Company
hereby represents and warrants to the Selling Stockholders that, as of the date
hereof, it is not party to any agreement with one or more third parties to
effect the registration under the Securities Act of all or part of any shares
of Common Stock or Class A Common Stock owned by such third parties on terms
that are more favorable to such third parties than the terms of this
Agreement.  Notwithstanding anything in
this Agreement to the contrary, the Company agrees with each of the Selling
Stockholders that, to the extent the Company agrees after the date hereof to
effect the registration under the Securities Act of all or part of any shares
of Common Stock owned by a third party, it shall only do so on terms that are
substantially identical to the terms of this Agreement.

 

(h)                                 Successors and
Assigns.  Cerro and SPC may
assign their respective rights and obligations under this Agreement solely to (w)
Cerro’s parent corporation, (x) Persons who are trust shareholders and/or
beneficiaries of Cerro’s parent corporation, (y) any Persons owned or
controlled by such trust shareholders and/or beneficiaries or (z) a transferee
of greater than 50% of the aggregate number of Registrable Securities owned by
Cerro and SPC as of the date hereof (such number to be adjusted proportionately
to reflect any stock dividend, stock split, reclassification, reorganization,
recapitalization, distribution or other similar event in respect of the
Shares); provided  that any such assignee shall first execute one
or more counterparts to this Agreement agreeing to be bound by its terms.  Climax and PDOCC may assign their respective
rights and obligations under this Agreement solely to (x) Persons who are
Affiliates of PDOCC and Climax or (y) a transferee of greater than 50% of the
aggregate number of Registrable Securities owned by Climax and PDOCC as of the
date hereof (such number to be adjusted proportionately to reflect any stock
dividend, stock split, reclassification, reorganization, recapitalization,
distribution or other similar event in respect of the Shares); provided  that
any such assignee shall first execute one or more counterparts to this
Agreement agreeing to be bound by its terms. 
Except as expressly set forth above in this Section 10(h),
the rights and obligations of the Selling Stockholders and the Permitted
Transferees under this Agreement shall not be assignable.  This Agreement is binding upon, inures to the
benefit of and is enforceable by the parties hereto and their respective
permitted successors and assigns.

 

(i)                                     Headings.  The headings used in this Agreement have been
inserted for convenience of reference only and do not define or limit the
provisions hereof.

 

(j)                                     Invalid
Provisions.  If any provision
of this Agreement is held to be illegal, invalid or unenforceable under any
present or future law, and if the rights or obligations of any party hereto
under this Agreement will not be materially and adversely affected thereby,
(i) such provision will be fully severable, (ii) this Agreement will
be construed and enforced as if such illegal, invalid or unenforceable
provision had never comprised a part hereof and (iii) the remaining
provisions of this Agreement will remain in full force and effect and will not
be affected by the illegal, invalid or unenforceable provision or by its
severance herefrom.

 

(k)                                  Remedies.  Except as otherwise expressly provided for
herein, no remedy conferred by any of the specific provisions of this Agreement
is intended to be exclusive of any other remedy, and each and every remedy
shall be cumulative and shall be in addition to every

 

24

 

other remedy given
hereunder or now or hereafter existing at law or in equity or by statute or
otherwise.  The election of any one or
more remedies by any party hereto shall not constitute a waiver by any such
party of the right to pursue any other available remedies.

 

Damages in the event of breach of this Agreement by a
party hereto or any other holder of Registrable Securities would be difficult,
if not impossible, to ascertain, and it is therefore agreed that each such
Person, in addition to and without limiting any other remedy or right it may
have, will have the right to an injunction or other equitable relief in any
court of competent jurisdiction, enjoining any such breach, and enforcing
specifically the terms and provisions hereof and the Company and each holder of
Registrable Securities, by its acquisition of such Registrable Securities,
hereby waives any and all defenses it may have on the ground of lack of
jurisdiction or competence of the court to grant such an injunction or other
equitable relief.  The existence of this
right will not preclude any such Person from pursuing any other rights and
remedies at law or in equity which such Person may have.

 

(l)                                     Governing
Law.  This Agreement shall be
governed by and construed in accordance with the laws of the State of New York.

 

(m)                               Counterparts.  This Agreement may be executed in any number
of counterparts, each of which will be deemed an original, but all of which
together will constitute one and the same instrument.

IN WITNESS WHEREOF, this Agreement has been duly
executed and delivered by the duly authorized officer of each party hereto as
