by the laws of the State of Delaware.

      2. TERMS AND CONDITIONS OF MERGER. At the Effective Time:

            (iii) the Merger shall have the effects stated in Sections 259, 260

      3. EFFECT OF THE MERGER ON CAPITAL STOCK. As of the Effective Time, as a
result of the Merger and without any action on the part of any holder thereof:

            (i) each holder of PBH Common Stock which is issued and outstanding
      immediately prior to the Effective Time shall automatically be entitled to
      receive that number of shares of iExalt Common Stock set forth opposite
      their respective names on SCHEDULE 3(I) attached hereto, for a total of
      273,932 fully paid and nonassessable shares of issued and outstanding

            (ii) each share of PBH Common Stock held in the treasury of PBH
      shall be canceled and retired;

            (iii) each share of Merger Sub Common Stock issued and outstanding
      immediately prior to the Effective Time will be converted into one share
      of Common Stock, par value $1.00 per share, of the Surviving Corporation,
      and the shares of Common Stock of the Surviving Corporation resulting from
      such conversion will constitute all of the issued and outstanding shares
      of capital stock of the Surviving Corporation; and

            (iv) in addition to the iExalt Common Stock issuable under Section
      3(i) above, the holders of PBH Common Stock immediately prior to the
      Effective Time shall be entitled to receive up to an additional 284,076

      Reorganization Agreement.

      Upon and after the Effective Time, no transfer of shares of PBH Common
Stock issued and outstanding immediately before the Effective Time shall be made
on the stock transfer books of the Surviving Corporation.

      Each holder of a certificate representing shares of PBH Common Stock
immediately before the Effective Time will, as of the Effective Time and
thereafter, cease to have any rights respecting those shares other than the
right to receive, without interest, the shares of iExalt Common Stock into which
his shares of PBH Common Stock shall have been converted as a result of the
Merger.

      4. DELIVERY, EXCHANGE AND PAYMENT.

      (A) SURRENDER OF CERTIFICATES. At or after the Effective Time: (i) each
holder of an outstanding certificate or certificates previously representing
shares of PBH Common Stock ("PBH STOCKHOLDER"), will, on surrender of his
certificate to iExalt, receive a certificate representing the number of shares
of iExalt Common Stock into which such shares of PBH Common Stock shall have
been converted as a result of the Merger, and (ii) until any certificate
representing PBH Common Stock is surrendered pursuant to this Section 4, that
certificate will, for all purposes, be deemed to evidence ownership of the
number of whole shares of iExalt Common Stock issuable in respect of that
certificate under Sections 3 and 5. All shares of iExalt Common Stock issuable
in the Merger will be deemed for all purposes to have been issued by iExalt at
the Effective Time.

      (B) CERTAIN TRANSFERS. In the event of a transfer of ownership of shares
of PBH Common Stock that is not registered in the transfer records of PBH, the
certificate representing shares of iExalt Common Stock issuable in respect of
such shares of PBH Common Stock may be issued to a transferee if the certificate
representing such shares of PBH Common Stock is presented to iExalt's transfer
agent, accompanied by all documents required to evidence and effect such
transfer and by evidence satisfactory to iExalt and its transfer agent that any
applicable stock transfer taxes have been paid.

      (C) LOST CERTIFICATES. If any certificate representing shares of PBH
Common Stock shall have been lost, stolen or destroyed, upon receipt of (i) an
affidavit of that fact from the PBH Stockholder claiming the certificate to be
lost, stolen or destroyed, (ii) such bond, security or indemnity as iExalt or
its transfer agent may reasonably require, and (iii) any other documentation
necessary to evidence and effect the bona fide exchange thereof, iExalt shall
cause its transfer agent to issue to such PBH Stockholder a certificate
representing the shares of iExalt Common Stock into which the shares of PBH
Common Stock represented by the lost, stolen or destroyed certificate would have
been exchanged.

      (D) DIVIDENDS AND DISTRIBUTIONS. No dividends (or interest) or other
distributions declared or earned after the Effective Time with respect to iExalt
Common Stock and payable to the holders of record thereof after the Effective
Time will be paid to the holder of any unsurrendered

                                       3

certificate representing shares of PBH Common Stock for which shares of iExalt
Common Stock have been issued in the Merger until the unsurrendered certificates
are surrendered as provided herein, but (i) on such surrender, iExalt will cause
to be paid, to the person in whose name the certificate representing such shares
of iExalt Common Stock shall then be issued, the amount of dividends or other
distributions previously paid with respect to such whole shares of iExalt Common
Stock with a record date, or which have accrued, subsequent to the Effective
Time, but prior to surrender, and (ii) at the appropriate payment date or as
soon as practicable thereafter, iExalt will cause to be paid to that person the
amount of dividends or other distributions with a record date, or which have
been accrued, subsequent to the Effective Time, but which are not payable until
a date subsequent to surrender, which are payable with respect to such number of
whole shares of iExalt Common Stock, subject in all cases to any applicable
escheat laws. No interest will be payable with respect to the payment of such
dividends or other distributions on surrender of outstanding certificates.
