(amounts in thousands)                           Amount
- ----------------------                        ------------
                                           
Goodwill                                      $     35,698
Assets acquired, net of liabilities assumed          4,302
                                              ------------
                                              $     40,000
                                              ============
</Table>

The purchase price allocation to the assets and liabilities assumed was based on
a preliminary estimate to determine their respective values. The Company
believes that the preliminary allocations set forth herein are reasonable, but
are subject to revision upon completion of a planned independent valuation
study.

2. KEY TO PRO FORMA ADJUSTMENTS

The unaudited pro forma condensed combined balance sheet and statements of
operations include the adjustments necessary to give effect to the purchase and
to reflect the allocation of the purchase price to the fair value of the assets
acquired as noted above, including the elimination of Cryogen, Inc.'s equity
accounts. Summarized below are the pro forma adjustments necessary to reflect
the acquisition of Cryogen, Inc. based upon the purchase method of accounting in
accordance with SFAS 141, Business Combinations.

(a)   Record the consideration paid for Cryogen, elimination of Cryogen equity
      accounts, and reflect the excess of the purchase price over the assets
      acquired.

(b)   Record the tax benefit from the net losses recorded by CryoGen.

(c)   To adjust net interest expense due to lower investment income from lower
      cash balances.
