Corp., and all of such minutes or other records of proceedings are correct and

each holder are set forth in Schedule 3.3. Except as listed in Schedule 3.3 or
as set forth above, there are no pre-emptive or other outstanding rights,
options, warrants, conversion rights, stock appreciation rights, redemption

sell any shares of capital stock or other securities of NISCO or any securities
or obligations convertible or exchangeable into or exercisable for, or giving
any person a right to subscribe for or acquire, any securities of NISCO, and no
securities or obligations evidencing such rights are authorized, issued or
outstanding. NISCO does not have outstanding any bonds, debentures, notes or
other debt obligations the holders of which have the right to vote (or
convertible into or exercisable for securities having the right to vote). There
are no outstanding or authorized stock appreciation, phantom stock, profit
participation, or similar rights with respect to NISCO. There are no voting

person acquired his or her stock in NISCO. Except as disclosed on Schedule 3.4
to the NISCO Disclosure Letter, NISCO has not been, within such period of time,
a subsidiary or division of another corporation or a part of an acquisition
which was later rescinded.

        3.5 SPIN-OFF BY NISCO. Except as set forth on Schedule 3.5 to the NISCO
Disclosure Letter, there has not been any sale, spin-off or split-up of material

is under common control with, NISCO ("Affiliates") since its inception.

        3.6 FINANCIAL STATEMENTS. Schedule 3.6 to the NISCO Disclosure Letter
includes copies of the following financial statements (the "NISCO Financial
Statements") of NISCO: NISCO's audited Balance Sheet as of December 31, 1999 and

principles ("GAAP") applied on a consistent basis throughout the periods

indicated thereon, except that the unaudited interim financial statements were
or are subject to normal and recurring year-end adjustments which were not or
are not expected to be material in amount.

        3.7 LIABILITIES AND OBLIGATIONS. Schedule 3.7 to the NISCO Disclosure
Letter includes accurate lists as of September 30, 2000 (the "Balance Sheet
Date") of (i) all material liabilities of NISCO which are not reflected on the
Balance Sheet of NISCO at the Balance Sheet Date or otherwise reflected in the
NISCO Financial Statements at the Balance Sheet Date which by their nature would
be required in accordance with GAAP to be reflected in the Balance Sheet, and
(ii) all loan agreements, indemnity or guaranty agreements, bonds, mortgages,
liens, pledges or other security agreements. Except as set forth on Schedule 3.7
to the NISCO Disclosure Letter, since the Balance Sheet Date NISCO has not
incurred any material liabilities of any kind, character and description,
whether accrued, absolute, secured or unsecured, contingent or otherwise, other
than liabilities incurred in the ordinary course of business. Schedule 3.7 to
the NISCO Disclosure Letter also includes, in the case of those contingent
liabilities related to pending or threatened litigation, or other liabilities

reasonable estimate of the maximum amount which NISCO reasonably expects will be
payable. For each such contingent liability or liability for which the amount is
not fixed or is contested, NISCO has provided to AMDI the following information:

            (d) A good faith and reasonable estimate of the maximum amount, if
any, which is likely to become payable with respect to each such liability. If
no estimate is provided, the estimate shall for purposes of this Agreement be
deemed to be zero.

        3.8 PERMITS AND INTANGIBLES.

            (i) NISCO holds all licenses, franchises, permits and other
governmental authorizations the absence of any of which could have a Material
Adverse Effect on NISCO's business and Schedule 3.8 to the NISCO Disclosure
Letter includes an accurate list and summary description of all such licenses,

Effect on NISCO. Except as specifically provided in Schedule 3.8 to the NISCO
Disclosure Letter, the transactions contemplated by this Agreement will not
result in a default under or a breach or violation of, or adversely affect the
rights and benefits afforded to NISCO by, any such licenses, franchises, permits
or government authorizations.

            (ii) The patents, the marks and copyrights, as well as the know how,

Property by such third party.

and other expenses of investigation and defense of any claims or actions),
directly or indirectly resulting from, relating to or arising out of: (i) any
breach of any covenant, agreement, warranty or representation of NISCO or the
Principal Shareholder contained in this Agreement, (ii) any misstatement of a
material fact contained in this Agreement or in any of the documents executed in
connection with the transactions contemplated by this Agreement, including the
Registration Statement, but only if the misstatement relates to information
concerning the Principal Shareholder or NISCO's operations, or (iii) the
omission to state any fact necessary to make the statements contained in this
Agreement or in any of the documents executed in connection with the
transactions contemplated by this Agreement not misleading, but only if the
omission relates to information concerning the Principal Shareholder or NISCO's
operations.

        12.2 INDEMNIFICATION BY AMDI AND MERGER CORP. Each of AMDI and Merger
Corp. agrees to indemnify and hold harmless the Principal Shareholder against
any and all losses, claims, damages, liabilities, costs and expenses (including
but not limited to, attorneys' fees and other expenses of investigation and
defense of any claims or actions) directly or indirectly resulting from,
relating to or arising out of: (i) any breach of any covenant, agreement,
warranty or representation of AMDI or Merger Corp. contained in this Agreement,
(ii) any misstatement of a material fact contained in this Agreement or in any
of the documents executed in connection with the transactions contemplated by

statements contained in this Agreement or in any of the documents executed in
connection with the transactions contemplated by this Agreement not misleading,
but only if the omission relates to information concerning AMDI or Merger Corp.

        12.3 INDEMNIFICATION NOTICE. Should any party (the "Indemnified Party")
suffer any loss, damage or expense for which another party (the "Indemnifying
Party") is obligated to indemnify and hold such Indemnified Party harmless
pursuant to this Section 12 of this Agreement, the following shall apply: If an
Indemnified Party intends to exercise its right to indemnification provided in
this Section 12, such Indemnified Party shall notify each Indemnifying Party in
writing of such Indemnified Party's intention to do so and the facts or
circumstances giving rise to the claim (the "Indemnification Claim"). An
Indemnification Claim, at the option of the Indemnified Party, may be asserted
as soon as any situation, event or occurrence has been noticed by the
Indemnified Party regardless of whether actual harm has been suffered or
out-of-pocket expenses incurred.

                                      -33-

<PAGE>   34


During the period of 15 days after notice by the Indemnified Party, each
Indemnifying Party shall be entitled to cure the defect or situation giving rise
to the Indemnification Claim to the satisfaction of the Indemnified Party. If
the Indemnifying Parties are unwilling or unable to cure the defect giving rise
to the Indemnification Claim during the 15-day period, the Indemnified Party
shall thereafter be entitled to indemnification as provided in this Section 12.

        12.4 MATTERS INVOLVING THIRD PARTIES. If any third party shall notify
any Indemnified Party with respect to any matter (a "Third Party Claim") which
may give rise to a claim for indemnification against any Indemnifying Party
under this Section 12, then the Indemnified Party shall promptly notify each
Indemnifying Party thereof in writing. Provided, however, that no delay on the
part of the Indemnified Party in notifying any Indemnifying Party shall relieve
the Indemnifying Party from any obligation hereunder unless (and then solely to
the extent) the Indemnifying Party thereby is prejudiced. Any Indemnifying Party
will have the right to defend the Indemnified Party against the Third Party
Claim with counsel of its choice reasonably satisfactory to the Indemnified
Party so long as (i) the Indemnifying Party notifies the Indemnified Party in
writing within 15 days after the Indemnified Party has given notice of the Third
Party Claim that the Indemnifying Party will indemnify the Indemnified Party
from any adverse consequences the Indemnified Party may suffer resulting from or
caused by the Third Party Claim, (ii) the Indemnifying Party provides the
Indemnified Party with evidence reasonably acceptable to the Indemnified Party
that the Indemnifying Party will have the financial resources to defend against
the Third Party Claim and fulfill its indemnification obligations hereunder, and
(iii) the Indemnifying Party conducts the defense of the Third Party Claim
actively and diligently. The Indemnifying Party shall not consent to the entry
of any judgment or enter into any settlement with respect to the Third Party
Claim without the prior written consent of the Indemnified Party, which consent
shall not be withheld unreasonably.
