acquire the UPC Securities to any person other than the Purchaser. The UPC
Securities have not been encumbered with an attachment, usufruct and pledge
nor have depositary receipts for the UPC Securities been issued with the
Purchaser's concurrence.

     (e) ACCREDITED INVESTOR. The Seller is aware that the UGC Shares have
not been registered under the Securities Act or any applicable state
securities laws. Such party understands that the UGC Shares are being offered

Seller is an "Accredited Investor" as that term is defined in Rule
501(a) of the Securities Act. The UGC Shares are being acquired solely for
the Seller's own account, for investment purposes only, and not for any
distribution, subdivision or fractionalization thereof; and the Seller has no
agreement or other arrangement, formal or informal, with any person or entity
to sell, transfer or pledge any part of the UGC Shares. The Seller further
understands that it must bear the economic risk of this investment for an
indefinite period of time because the Seller cannot resell or otherwise
transfer any part of the UGC Shares unless (i) the UGC Shares are first
registered under the Securities Act and such resale or other transfer
complies with all applicable state securities laws or (ii) exemptions from
the requirements of the Securities Act and all applicable state securities
laws are available.

     (f) ACCESS TO INFORMATION. The Seller has adequate information
concerning the businesses, finances and operations, condition (financial and
otherwise), results of operations, properties, plans and prospects of the
Purchaser to make an informed decision regarding the sale and has
independently and without reliance upon the Purchaser made its own analysis
and decision to sell. The Seller has been afforded the opportunity to ask
questions of the Purchaser and has received satisfactory answers to any such
inquiries.

     (g) NEGOTIATED AGREEMENT. The terms of this Agreement were the result
of negotiations between the Seller and the Purchaser, and the Seller was
given the opportunity to review and comment upon the proposed terms of this
Agreement.

     (h) DISCLOSURE STATEMENT. The Seller has received a copy of the
Disclosure Statement.

     SECTION 5. Registration.

            (a) The Purchaser shall include the UGC Shares in the next
shelf registration statement filed with the Commission pursuant to Rule
415 under the Securities Act of 1933, as amended (the "Act") relating to
the sale of shares of UGC Common Stock by persons other than the Purchaser,
or amend an existing registration statement (the "Shelf Registration
Statement"), and provide for the registration of all of the UGC Shares.

            (b) Seller may not include the UGC Shares in any Shelf
Registration Statement pursuant to this Agreement unless and until the Seller
(i) agrees to

                                       4

be named as a selling stockholder in the related Prospectus and to deliver a
Prospectus to purchasers and (ii) furnishes to the Purchaser in writing,
within 15 days after receipt of a request therefor, certain
representations and information with respect to itself and the proposed
distribution by it as shall be necessary in order to assure compliance with
Federal and applicable state securities laws in connection with the Shelf
Registration Statement in order to have the UGC Shares included in the Shelf
Registration Statement. The Seller agrees to promptly furnish additional
information required to be disclosed in order to make the information
previously furnished to the Purchaser by the Seller not materially
misleading. The Purchaser may exclude from such registration the UGC Shares
if Seller fails to furnish such information within a reasonable time after
receiving such request.
