                                   THE MERGER

         1.1 Merger. At the Effective Time (as defined in Section 1.2), IA

         1.2 Effective Time of Merger. The Articles of Merger setting forth the
information required by, and otherwise in compliance with, the Texas Business
Corporation Act with respect to the Merger, shall be delivered for filing with
the Secretary of State of the State of Texas. Certified copies of the Articles
of Merger and the Agreement and Plan of Merger ("Certified Copies"), issued by
the Secretary of State of the State of Texas and setting forth the information
required by, and otherwise in compliance with the General Corporation Law of the
State of Arizona, shall be delivered for filing to the Arizona Corporation
Commission. The Merger shall become effective on the day and at the time the
Secretary of State of the State of Texas files such Articles of Merger (the time
of such effectiveness is herein called the "Effective Time"). Notwithstanding
the foregoing, either IA Arizona or IA Texas, by action of its Board of
Directors, may terminate this Agreement at any time prior to the earlier of (i)
the filing of the Articles of Merger with the Secretary of State of the State of
Texas or (ii) the filing of the Certified Copies with the Arizona Corporation
Commission.

         1.3 Effects of Merger. At the Effective Time, IA Texas, without further
action, as provided by the laws of the State of Arizona and the laws of the
State of Texas, shall succeed to and possess all of the rights, privileges,
powers, and franchises, of a public as well as of a private nature, of IA
Arizona; and all property, real, personal and mixed, and all debts due on
whatsoever account, including subscriptions to shares, and all other choses in
action, and all and every other interest, of or belonging to or due to IA
Arizona shall be deemed to be vested in IA Texas without further act or deed;
and the title to any real estate, or any interest therein, vested in IA Texas or
IA Arizona shall not revert or be in any way impaired by reason of the Merger.
Such transfer to and vesting in IA Texas shall be deemed to occur by operation
of law, and no consent or approval of any other person shall be required in
connection with any such transfer or vesting unless such consent or approval is
specifically required in the event of merger or consolidation by law or express
provision in any contract, agreement, decree, order, or other instrument to
which IA Texas or IA Arizona is a party or by which either of them is bound. IA
Texas shall thenceforth be responsible and liable for all debts, liabilities,
and duties of IA Arizona which may be enforced against IA Texas to the same
extent as if said debts, liabilities, and duties had been incurred or contracted
by it. Neither the rights of creditors nor any liens upon the property of IA
Arizona and IA Texas shall be impaired by the Merger.

         1.4 Articles of Incorporation. The Articles of Incorporation of IA
Texas before the merger shall be and remain the Articles of Incorporation of IA
Texas after the Effective Time, until the same shall thereafter be altered,
amended, or repealed in accordance with law and IA Texas's Articles of
Incorporation; provided, however, that at the time of the Merger the Articles of
Incorporation of IA Texas shall be amended as provided on Exhibit I, attached
hereto and incorporated herein by reference, in order to change the name of the
