          6.1  Employees.  OC shall make available to the Company those OC
               ---------
employees who are engaged in the Business (whether salaried or hourly, union or
non-union and full time or part time) so long as such employees are employed by
OC. Such employees shall not be considered employees of the Company and OC shall
continue to provide salaries and benefits to such employees.

                                       6

 
          6.2  Insurance.  OC shall maintain its current levels of liability,
               --------- 
hazard, property and casualty insurance (including deductibles and self
retention amounts for which the Company shall be solely responsible) in respect

          6.3  No Third-Party Beneficiary.  Nothing herein, expressed or
               --------------------------
implied, shall confer upon any employee or former employee of OC or the Company
or any of their Affiliates (including, without limitation, the employees of the
Business), any rights or remedies including, without limitation, any right to
employment or continued employment for any specified period) of any nature or
kind whatsoever, under or by reason of this Agreement. 

     7.   Indemnification.
          --------------- 

          7.1  Indemnification by OC. (a) OC shall defend, indemnify and hold
               ---------------------
the Company and its members harmless from and against and in respect of any and
all losses, liabilities, damages, claims, suits, Taxes, demands, proceedings,
judgments, settlements and expenses (whether or not arising out of third party
claims), including reasonable attorneys' fees, incurred directly by the Company
arising out of (i) the ownership, operation or use of any of the Excluded
Assets, (ii) the Excluded Liabilities or (iii) any failure of the Metal Assets
to meet the quantity or purity specifications set forth in the definition
thereof. The Company shall give OC prompt written notice of any third party
claim which may give rise to any indemnity obligation under this Section,
together with the estimated amount of such claim, and OC shall have the right to
assume the defense of any such claim through counsel of its own choosing, by so
notifying the Company within thirty (30) days of receipt of the Company's
written notice; provided, however, that OC's counsel shall be reasonably
                --------  ------- 
satisfactory to the Company. Failure to give prompt notice shall not affect the
indemnification obligations hereunder in the absence of actual prejudice. If the
Company desires to participate in any such defense assumed by OC, it may do so
at its sole cost and expense. If OC declines to assume any such defense, the
Company shall have the right to undertake the defense, compromise or settlement
of such claim and OC shall be liable for all reasonable costs and expenses of
defending such claim incurred by the Company, including reasonable fees and
disbursements of counsel. Neither party shall, without the prior written consent
of the other party, which shall not be unreasonably withheld, settle, compromise
or offer to settle or compromise any such claim or demand on a basis which would
result in the imposition of a consent order, injunction or decree which would
restrict the future activity or conduct of the other party or any subsidiary or
Affiliate thereof or if such settlement or compromise does not include an
unconditional release of the other party for any liability arising out of such
claim or demand or any related claim or demand. The indemnity provided in this
Section 7.1 shall be the sole and exclusive remedy of the Company against OC at
law or equity; provided that nothing in this Section 7.1 shall otherwise limit
either party from seeking temporary or permanent injunctive relief for any
breach of Sections 3, 4 or 5 of this Agreement. In no event shall OC be liable
to the Company for special, indirect, incidental, consequential or punitive
damages, but, to the extent the Company is required to pay punitive damages to a
third party, such payment shall constitute an indemnifiable expense.

                                       7

 
               (b)  The foregoing obligation to indemnify the Company set forth
in Section 7.1(a) shall be subject to each of the following limitations:

                    (i)  OC's indemnification obligation for such Excluded
Liabilities with respect to matters relating to the investigation, remediation,
cleanup, removal or monitoring of Hazardous Substances at or migrating from the
Real Property ("Remedial Action") shall be limited to compliance with standards
established under applicable Environmental Laws (including, without limitation,
the imposition of institutional or engineering controls, deed restrictions,
natural attenuation, capping and site-specific risk-based standards), based on
the existing use of the relevant Real Property as of the Closing Date.

                    (ii) Notwithstanding anything to the contrary in this
Agreement, Seller shall have satisfied its indemnification obligation and shall
be released from any further indemnification obligation or liability for any
Remedial Action in the event and to the extent it receives a notice of final
approval (including, without limitation, a no further action letter, certificate
of completion, or release-and-covenant-not-to-sue) from a state or federal
Governmental or Regulatory Authority with jurisdiction over the relevant Real
Property pursuant to a clean-up program, voluntary or otherwise.

          7.2  Indemnification by the Company.  The Company shall defend,
               ------------------------------
indemnify and hold OC and its Affiliates harmless from and against and in
respect of any and all losses, liabilities, damages, claims, suits, Taxes,
demands, proceedings, judgments, settlements and expenses (whether or not
arising out of third party claims), including reasonable attorney's fees,
incurred directly by OC and its Affiliates arising out of (i) the ownership,
operation or use of the Business or the Assets on or after the date hereof or
(ii) the Assumed Liabilities. OC shall give the Company prompt written notice of
any third party claim which may give rise to any indemnity obligation under this
Section, together with the estimated amount of such claim, and the Company shall
have the right to assume the defense of any such claim through counsel of its
own choosing, by so notifying OC within thirty (30) days of receipt of OC's
written notice; provided, however, that the Company's counsel shall be
                --------  -------
reasonably satisfactory to OC. Failure to give prompt notice shall not affect
the indemnification obligations hereunder in the absence of actual prejudice. If
OC desires to participate in any such defense assumed by the Company, it may do
so at its sole cost and expense. If the Company declines to assume any such
defense, OC shall have the right to undertake the defense, compromise or
settlement of such claim and the Company shall be liable for all costs and
expenses of defending such claim incurred by OC, including reasonable fees and
disbursements of counsel. Neither party shall, without the prior written consent
of the other party, which shall not be unreasonably withheld, settle, compromise
or offer to settle or compromise any such claim or demand on a basis which would
result in the imposition of a consent order, injunction or decree which would
restrict the future activity or conduct of the other party or any subsidiary or
Affiliate thereof or if such settlement or compromise does not include an
unconditional release of the other party for any liability arising out of such
claim or demand. The indemnity provided in this Section 7.2 shall be the sole
and exclusive remedy of OC against the Company at law or equity for the matters
