may request to ensure that the Distributions and the Other Transactions qualify
for the tax-free treatment stated in the IRS Ruling, including, without
limitation, such actions as ATI determines may be necessary to preserve the
validity of the IRS Ruling. Without limiting the generality of the foregoing,
SPINCO and the SPINCO Group shall cooperate with ATI if ATI, in its sole
discretion, determines to obtain additional or supplemental IRS rulings
pertaining to whether any actual or proposed change in facts and circumstances
affects the tax-free status of the Distribution or the Other Transactions.
Regardless of the fact that ATI shall control matters set forth in the preceding
sentence of this Section 5.2(b), the ATI Consolidated Group, on one hand, and
SPINCO and the SPINCO Group, on the other



                                       10
   11


hand, shall equally bear responsibility for all expenses associated with any
such additional or supplemental IRS rulings; provided, however, that any
expenses associated with any additional or supplemental IRS Rulings based on a
proposed action or omission by SPINCO or a member of the SPINCO Group will be
borne solely by SPINCO.

         (c) Following the Effective Date, SPINCO and its Affiliates shall not
take any action or engage in conduct otherwise prohibited by Section 5.2 unless
prior to such action or conduct, as the case may be, SPINCO receives express
written consent from ATI which consent will be granted, if at all, in the sole
discretion of ATI.

         (d) SPINCO will consummate the Public Offering within one year after
the Effective Date and will use the Public Offering proceeds in the manner and
during time periods set forth in the Ruling Request.

         (e) If, within two years after the Public Offering, SPINCO disposes of
any assets, other than inventory, SPINCO will use the proceeds (net of tax and
transaction costs) from such disposition in a manner that is, in ATI's sole
discretion, consistent with the business purpose of expanding SPINCO's business
as set forth in the Ruling Request.

                                   ARTICLE VI
                          SPINCO INDEMNITY OBLIGATIONS

         SECTION 6.1. SPINCO INDEMNITY. If SPINCO, or another member (or former
member) of the SPINCO Group (collectively, the "Indemnifying Parties") takes or
fails to take any action whether or not prohibited or required by Article V or
violates a representation or covenant in Article V or in the Ruling Request, and
the Distribution or any of the Other Transactions fail to or otherwise do not
qualify for the tax treatment stated in the IRS Ruling as a result of such
action, failure to take action, or violation, then the Indemnifying Parties
shall jointly and severally defend, indemnify and hold harmless ATI and each
member of the ATI Consolidated Group and each of their respective directors,
officers, employees, agents or other representatives (collectively, and/or
individually, as the case may be, the "Indemnified Party") against any liability
for such Taxes which the Indemnified Party may assume or otherwise incur and any
and all Taxes or other liabilities directly or indirectly imposed upon or
incurred by the Indemnified Party as a result of such failure or lack of
qualification, including, without limitation, any liability of the Indemnified
Party arising from Taxes imposed on stockholders of ATI whether or not any
stockholder or stockholders of ATI, or the IRS or other taxing authority,
successfully seeks recourse against the Indemnified Party on account of any such
failure.

         SECTION 6.2. TENDER OFFER OR PURCHASE OFFER. Notwithstanding anything
to the contrary set forth in this Agreement, if, during the Restricted Period,
any Person or Group of Affiliated Persons or Associates acquires Beneficial
Ownership of SPINCO common stock (or any other class of outstanding SPINCO
stock) or commences a tender or other purchase offer for the capital stock of
SPINCO or initiates any other form of transaction to acquire directly or
indirectly SPINCO capital stock, upon consummation of which such Person or Group
of Affiliated Persons or Associates would acquire Beneficial Ownership of SPINCO
common stock



                                       11
   12


(or any other class of outstanding SPINCO stock or equity) and as a result
thereof the Distribution or any of the Other Transactions shall fail to or
otherwise do not qualify for the tax treatment stated in the IRS Ruling then the
Indemnifying Parties shall defend, indemnify and hold harmless the Indemnified
Party against any liability for Taxes which the Indemnified Party may assume or
otherwise incur and any and all Taxes or other liabilities directly or
indirectly imposed upon or incurred by any Indemnified Party and/or its
stockholders as a result of such failure.

         SECTION 6.3. EFFECT OF EXPRESS WRITTEN CONSENT OF ATI. The Indemnified
Party shall be defended, indemnified and held harmless under Section 6.1 without
regard to the fact that the Indemnifying Party may have received the express
written consent of ATI as contemplated by Article V. The Indemnified Party shall
be defended, indemnified and held harmless under Section 6.2 whether or not the
acquisition of Beneficial Ownership results from a transaction which is not
prohibited under Article V.

                                   ARTICLE VII
                     CALCULATION OF SPINCO INDEMNITY AMOUNTS

         SECTION 7.1. AMOUNT OF INDEMNITY. The amount indemnified against under
Article VI ("Indemnified Liability") for a Tax based on or determined with
reference to income shall be deemed to be, for each applicable taxing
jurisdiction, an amount determined by multiplying (i) the taxing jurisdiction's
highest marginal corporate income or tax rate for the taxable period in which
the Distribution or Other Transaction occurs, times (ii) the gain or income of
the Indemnified Party which is subject to such Tax. In the case of other
Indemnified Liabilities, the amount of the Indemnified Liability shall be equal
to the amount so owed. In addition, the amount of any Indemnified Liability
shall be increased by any interest, costs, legal and professional fees,
additions, expenses and penalties incurred by the Indemnified Party. All amounts
payable under this Article VII shall, to the extent that such amounts constitute
taxable income, be grossed-up, based on the tax rate referred to in clause (i)
of the first sentence of this Section 7.1.

                                  ARTICLE VIII
                     PROCEDURAL ASPECTS OF SPINCO INDEMNITY

         SECTION 8.1.  GENERAL.

         (a) If either the Indemnified Party or any of the Indemnifying Parties
receives any written notice of deficiency, claim or adjustment or any other
written communication from a taxing authority or any other Person that may
result in an Indemnified Liability, the party receiving such notice or
communication shall promptly give written notice thereof to the other parties,
provided that any delay by the Indemnified Party in so notifying an Indemnifying
Party shall not relieve the Indemnifying Party of any liability hereunder,
except to the extent the Indemnifying Party is materially and adversely
prejudiced by such delay.

         (b) Each party hereto undertakes and agrees that from and after such
time as it obtains knowledge that any representative of a taxing authority has
begun to investigate or inquire into the Distribution or any of the Other
Transactions (whether or not such investigation or inquiry is a



                                       12
   13


formal or informal investigation or inquiry), such party shall (i) notify the
other parties thereof, provided that any delay by the Indemnified Party in so
notifying the Indemnifying Party shall not relieve the Indemnifying Party of any
liability hereunder (except to the extent the Indemnifying Party is materially
and adversely prejudiced by such delay), (ii) consult with the other parties
from time to time as to the conduct of such investigation or inquiry, (iii)
provide the other parties with copies of all correspondence with such taxing
authority or any representative thereof or other Person pertaining to such
investigation or inquiry, and (iv) arrange for a representative of the other
parties to be present at all meetings with such taxing authority or any
representative thereof pertaining to such investigation or inquiry.

         (c) SPINCO undertakes and agrees to give full cooperation and support
to ATI, including without limitation, attestations and/or access to Information,
as requested by ATI, to document and verify the use of the Public Offering
proceeds in the manner and during the time period set forth in the Ruling
Request. SPINCO will submit a quarterly accounting to ATI, due within 30 days
after the end of each calendar quarter, which sets forth in detail the use of
Public Offering proceeds. This information will be submitted to ATI in a format
substantially similar to the chart attached hereto as Appendix I.

         SECTION 8.2. CONTESTS.

         (a) If (i) the Indemnifying Party furnishes the Indemnified Party with
evidence satisfactory to the Indemnified Party of its ability to pay the full
amount of the Indemnified Liability and (ii) such Indemnifying Party
acknowledges in writing that the asserted liability is an Indemnified Liability,
such Indemnifying Party may assume and direct the tax examination,
administrative appeal, hearing, arbitration, suit or other proceeding (each a
"Proceeding") commenced, filed or otherwise initiated or convened to investigate
or resolve the existence and extent of such Indemnified Liability.

         (b) Notwithstanding the foregoing, if at any time during a Proceeding
controlled by the Indemnifying Party pursuant to Section 8.2(a), such
Indemnifying Party fails to provide evidence satisfactory to the Indemnified
Party of its continuing ability to pay the full amount of the Indemnified
Liability or the Indemnified Party determines that such Indemnifying Party may
be unable to pay the full amount of the Indemnified Liability, then the
Indemnified Party may immediately assume control of and direct the Proceedings.

         (c) During the period in which the Indemnifying Party assumes and
directs the Proceeding, if the Indemnified Liability is grouped with other
unrelated asserted liabilities or issues in the Proceeding, the parties shall
use their respective best efforts to cause the Indemnified Liability to be the
subject of a separate proceeding. If such severance is not possible, the
Indemnifying Party shall assume and direct and be responsible only for the
matters relating to the Indemnified Liability.

         (d) In addition to the amounts referred to in Section 6.1, an
Indemnifying Party shall pay all out-of-pocket expenses and other costs related
to the Indemnified Liability, including but not limited to fees for attorneys,
accountants, expert witnesses or other consultants retained by



                                       13
   14


such Indemnifying Party and/or the Indemnified Party with respect to a claim
pursuant to this Agreement. To the extent that any such expenses and other costs
have been or are paid by an Indemnified Party, the Indemnifying Party shall
promptly upon written request reimburse the Indemnified Party therefor.

         (e) An Indemnifying Party shall not pay (unless otherwise required by a
proper notice of levy and after prompt written notification to the Indemnified
Party of receipt of notice and demand for payment), settle, compromise or
concede any portion of the Indemnified Liability without the express written
consent of the Indemnified Party. An Indemnifying Party shall, on a timely
basis, keep the Indemnified Party informed of all developments in the Proceeding
and provide the Indemnified Party with copies of all pleadings, briefs, orders,
and other written papers; provided that in the event that the Indemnifying Party
determines that the providing of a written paper could waive an attorney-client
privilege, the parties shall take all reasonable measures to permit the
compliance with such obligation in a manner that avoids such consequence.

         (f) Any Proceeding which is not controlled or which is no longer
controlled by an Indemnifying Party pursuant to Section 8.2 shall be controlled
and directed exclusively by the Indemnified Party, and any related out-of-pocket
expenses and other costs incurred by the Indemnified Party, including but not
limited to, fees for attorneys, accountants, expert witnesses or other
consultants, with respect to a claim pursuant to this Agreement, shall be
reimbursed by such Indemnifying Party. An Indemnified Party will not be required
to pursue the claim in federal district court, the Court of Federal Claims or
any state or foreign court if as a prerequisite to such court's jurisdiction,
the Indemnified Party is required to pay the asserted liability unless the funds
necessary to invoke such jurisdiction are provided by such Indemnifying Party.

         SECTION 8.3. TIME AND MANNER OF PAYMENT. Upon receipt of notice of a
Final Determination, an Indemnifying Party shall pay, within seven (7) business
days of such receipt, to the Indemnified Party the amount of the Indemnified
Liability and any expenses or other costs indemnified against (less, in the case
of an Indemnified Liability for Taxes, any amount of such Taxes paid directly by
an Indemnifying Party to the taxing authority). With respect to payments of an
Indemnified Liability for amounts other than Taxes including any and all
Liabilities with respect to ATI stockholders, the Indemnifying Party shall pay
to the Indemnified Party the amount of this Indemnified Liability within seven
(7) days of a final determination of the amount of such Liability and, in the
case of Liabilities with respect to ATI stockholders, no less than seven (7)
days prior to the date that payment is required to be made to such stockholders.
Such payment shall be paid by wire transfer of immediately available funds to an
account designated by the Indemnified Party by written notice to an Indemnifying
Party at the address specified in Section 10.11 prior to the due date of such
payment. If an Indemnifying Party delays making payment beyond the due date
hereunder, such party shall pay interest on the amount unpaid at the IRS
Interest Rate for each day and the actual number of days for which any amount
due hereunder is unpaid.

         SECTION 8.4. COOPERATION. The parties shall cooperate with one another
in a timely manner in any administrative or judicial Proceeding involving any
matter that may result in an Indemnified Liability.

         SECTION 8.5. ADMINISTRATION. ATI's and SPINCO's Chief Tax Officer or
other designated tax representative shall have primary responsibility for the
day-to-day administration of the provisions of this Agreement.

                                   ARTICLE IX
                                    DISPUTES

         SECTION 9.1. DISPUTES.

         (a) Resolution of any and all disputes arising from or in connection
with this Agreement, whether based on contract, tort, statute or otherwise,
including, but not limited to, unreasonable withholding of consent and disputes
in connection with claims by third parties (collectively, "Disputes"), shall be
subject to the provisions of this Section 9.1; provided, however, that nothing
contained herein shall preclude either party from seeking or obtaining (i)
injunctive relief or (ii) equitable or other judicial relief to enforce the
provisions hereof or to preserve the status quo pending the final resolution of
Disputes hereunder.

         (b) Either party may give the other party written notice of any Dispute
not resolved in the normal course of business. The parties shall attempt in good
faith to resolve any Dispute promptly by negotiation between executives of the
parties who have authority to settle the controversy. Within 15 days after
delivery of the notice, the foregoing executives of both parties shall meet at a
mutually acceptable time and place, and thereafter as often as they reasonably
deem necessary for a period not to exceed 5 days, to attempt to resolve the
Dispute. All reasonable requests for information made by one party to the other
will be honored. If the parties do not resolve the Dispute within such 20 day
period (the "Initial Mediation Period"), the parties shall attempt in good faith
to resolve the Dispute by negotiation between (a) in the case of ATI, the Chief
Financial Officer and General Counsel, and (b) in the case of SPINCO, the Chief
Financial Officer and General Counsel (collectively, the "Designated Officers").
Such officers shall meet at a mutually acceptable time and place (but in any
event no later than 20 days following the expiration of the Initial Mediation
Period) and thereafter as often as they reasonably deem necessary for a period
not to exceed 20 days, to attempt to resolve the Dispute.

         (c) If the Dispute has not been resolved by negotiation within 50 days
of the first party's notice, or if the parties failed to meet within 15 days of
the first party's notice, or if the Designated Officers failed to meet within 35
days of the first party's notice, either party may commence any litigation or
other procedure allowed by law.

                                    ARTICLE X
                                     GENERAL

         SECTION 10.1. ELECTIONS UNDER CODE SECTION 1552. Nothing in this
Agreement is intended to change or otherwise affect any election made by or on
behalf of the ATI Consolidated Group with respect to the calculation of earnings
and profits under Code Section 1552.

         SECTION 10.2. PRE-DISTRIBUTION EARNINGS AND PROFITS. ATI and SPINCO
agree to allocate pre-Distribution earnings and profits in accordance with
Treasury Regulation Sections 1.312-10 and 1.1502-33.

         SECTION 10.3. REMEDIES. SPINCO acknowledges that its obligations under
Article V of this Agreement are of a special, unique, unusual and extraordinary
character. Because the failure of SPINCO to perform its obligations set forth in
Article V of this Agreement could cause unique and extraordinary injury to ATI,
ATI shall, notwithstanding anything to the contrary herein, have the right in
addition to any other remedies available, at law or in equity, to seek an
injunction in a court of equity to compel SPINCO to perform such obligations.
SPINCO hereby waives any and all defenses it may have on the ground of lack of
jurisdiction or competence of the court to grant an injunction or other
equitable relief, or otherwise, and agrees that it will not assert any such
defense or any defense to a request by ATI for injunctive relief based on the
alleged existence of an adequate remedy at law or for money damages. Without
limiting the foregoing, SPINCO hereby waives the right to require ATI to post
any bond or other security with respect to any proceeding to enforce any
provisions of this Agreement. The existence of the rights of ATI set forth in
this Section 10.3 shall not preclude any other rights and remedies at law or in
equity which ATI may have.

         SECTION 10.4. ASSIGNMENT. Neither of the parties may assign or delegate
any of its rights or duties under this Agreement without the prior written
consent of the other party. This Agreement shall be binding upon, and shall
inure to the benefit of, the parties hereto and their respective successors and
permitted assigns, by merger, acquisition of assets or otherwise.

         SECTION 10.5. FURTHER ASSURANCES. Subject to the provisions hereof, the
parties hereto shall make, execute, acknowledge, and deliver such other
instruments and documents, and take all such other actions, as may be reasonably
required in order to effectuate the purposes of this Agreement and to consummate
the transactions contemplated hereby. Subject to the provisions hereof, each of
the parties shall, in connection with entering into this Agreement, performing
its obligations hereunder and taking any and all actions relating hereto, comply
with all applicable laws, regulations, orders, and decrees, and promptly provide
the other parties with all such information as they may reasonably request in
order to be able to comply with the provisions of this Agreement.

         SECTION 10.6. WAIVERS. No failure or delay on the part of the parties
in exercising any power or right hereunder shall operate as a waiver thereof,
nor shall any single or partial exercise of any such right or power, or any
abandonment or discontinuance of steps to enforce



                                       16
   17


such right or power, preclude any other or further exercise thereof or the
exercise of any other right or power. No modification or waiver of any provision
of this Agreement nor consent to any departure by the parties therefrom shall in
any event be effective unless the same shall be in writing, and then such waiver
or consent shall be effective only in the specific instance and for the purpose
for which given.

         SECTION 10.7. CHANGE OF LAW. If, due to any change in applicable law or
regulations or their interpretation by any court of law or other governing body
having jurisdiction subsequent to the date of this Agreement, performance of any
provision of this Agreement or any transaction contemplated thereby shall become
impracticable or impossible, the parties hereto shall use their best efforts to
find and employ an alternative means to achieve the same or substantially the
same result as that contemplated by such provision.

         SECTION 10.8. CONFIDENTIALITY. Subject to any contrary requirement of
law and the right of each party to enforce its rights hereunder in any legal
action, each party agrees that it shall keep strictly confidential, and shall
cause its employees and agents to keep strictly confidential, any information
which it or any of its employees or agents may acquire pursuant to, or in the
course of performing its obligations under, any provision of this Agreement.

         SECTION 10.9. HEADINGS. Descriptive headings are for convenience only
and shall not control or affect the meaning or construction of any provision of
this Agreement.

         SECTION 10.10. COUNTERPARTS. For the convenience of the parties, any
number of counterparts of this Agreement may be executed by the parties hereto,
and each such executed counterpart shall be, and shall be deemed to be, an
original instrument.

         SECTION 10.11. NOTICES. All notices, requests, claims and other
communications hereunder shall be in writing and shall be given or made (and
shall be deemed to have been duly given or made upon receipt) by delivery by
hand, by reputable overnight courier service, by facsimile transmission, or by
registered or certified mail (postage prepaid, return receipt requested) to the
respective parties at the addresses (or at such other address for a party as

provided herein, each party agrees to pay its own costs and expenses resulting
from the fulfillment of its respective obligations hereunder.

         SECTION 10.13. CANCELLATION OF PRIOR TAX ALLOCATION OR TAX-SHARING
AGREEMENTS. On or prior to the Effective Date, ATI shall cancel or cause to be
canceled all agreements (other than this Agreement) providing for the allocation
or sharing of Taxes to which any member of the SPINCO Group would otherwise be
bound following the Distribution.

         SECTION 10.14. INTEREST ON LATE PAYMENTS. If a party makes any payment
beyond the due date hereunder, such party shall pay interest on the amount
unpaid at the IRS Interest Rate for each day and the actual number of days for
which any amount due hereunder is unpaid.

         SECTION 10.15. POWER OF ATTORNEY. Each member of the SPINCO Group shall
execute and deliver to ATI any power of attorney or other document reasonably
requested by ATI in connection with the filing of the Tax Returns and payment of
Taxes described in Article II hereof, or any Proceeding described in Article
VIII hereof. Each member of the ATI Consolidated Group shall execute and deliver
to SPINCO a power of attorney in connection with any matters controlled by
SPINCO under Section 2.2.

         SECTION 10.16. GENERAL. This Agreement, including the attachments,
shall constitute the entire agreement between the parties hereto with respect to
the subject matter hereof and shall supersede all prior agreements and
undertakings, both written and oral, between the parties with respect to the

                                       18
   19


herein, express or implied, is intended to or shall confer upon any third

under or by reason of this Agreement.

         SECTION 10.17. GOVERNING LAW: CONSENT TO JURISDICTION.

         (a) This Agreement shall be governed by and construed and interpreted
in accordance with the laws of the Commonwealth of Pennsylvania as to all
matters, including matters of validity, construction, effect, enforceability,
performance and remedies, irrespective of the choice of laws and principles of
the laws of the Commonwealth of Pennsylvania.

         (b) Each of the parties hereto irrevocably submits to the exclusive
jurisdiction of (i) the Court of Common Pleas of Allegheny County, Pennsylvania
and (ii) the United States District Court for the Western District of
Pennsylvania, for the purposes of any suit, action or other proceeding arising
out of this Agreement or any transaction contemplated hereby or thereby (and
agrees not to commence any action, suit or proceeding relating thereto except in
such courts). Each of the parties hereto further agrees that service of any
process, summons, notice or document hand delivered or sent by U.S. registered
mail to such parties respective address set forth in Section 10.11 will be
effective service of process for any action, suit or proceeding in Pennsylvania
with respect to any matters to which it has submitted to jurisdiction as set

shall negotiate in good faith to modify this Agreement so as to effect the
original intent of the parties as closely as possible in an acceptable manner in
order that the transactions contemplated hereby are consummated as originally
contemplated to the greatest extent possible.
