                         REAL ESTATE PURCHASE AGREEMENT

         THIS REAL ESTATE PURCHASE AGREEMENT (this "Agreement") is made as of
the 23rd day of December, 1998 by and among SALEX HOLDING CORP. ("Salex") and
SALVATORE CRIMI ("Crimi"), jointly (collectively, "Seller"); and SUN ASSOCIATES,
LLC ("Buyer").

RECITALS:

         Seller represents that Crimi is the holder of record title to the
Property, but Salex owns the Property pursuant to an unrecorded deed. Seller
desires to sell, and Buyer desires to purchase, all of Seller's interest in
certain real property (the "Land") located in the Town of Smithtown (Village of
Hauppauge), County of Suffolk and State of New York, on the terms and conditions
set forth herein. The Land, together with all improvements located thereon, is
referred to as the "Property." A description of the Property according to its
outer boundaries is set forth in Exhibit A annexed hereto. Simultaneously, at
the closing, Buyer has agreed to lease the Property to Seller, and Seller has
agreed to lease the Property from Buyer, on the terms and conditions of the
lease annexed hereto as Exhibit B (the "Lease")

WITNESSETH:

         NOW, THEREFORE, in consideration of the foregoing premises and the
promises contained herein, and for other good and valuable consideration, the
receipt and sufficiency of which are hereby acknowledged, and intending to be
legally bound, the parties hereto hereby agree as follows:

         1. Purchase and Sale. Seller agrees to sell the Property to Buyer, and
Buyer agrees to purchase the Property from Seller, upon all of the terms,
covenants and conditions set forth in this Agreement. The purchase price for the
Property (the "Purchase Price") shall be equal to ONE MILLION ONE HUNDRED
THOUSAND DOLLARS ($1,100,000.00). On the Closing Date, Buyer shall pay the
Purchase Price to Salex by certified check, bank check or, at Seller's option,
by wire transfer of immediately available funds into an account designated by
Salex. Salex acknowledges that the Purchase Price represents a fair price for
the Property in any event, and particularly in light of the current
circumstances, including, without limitation, the savings of any brokerage
commissions, the favorable rent set forth in the Lease, and the preservation of
the Property against foreclosure, which would cause irreparable harm to Salex's
business, and that this transaction is in the best interests of Salex.

         2. Closing Date. The closing date will be on or before December 30,
1998, after Buyer's approval of the title search and inspection of the Property.

         3. Buyer's Review. (a) From the date hereof until the closing date,
Buyer shall be permitted to make a physical inspection of the Property, and a
review of available records relating to the Property, applicable laws, and other

<PAGE>


matters and conditions affecting the Property. If Buyer determines, in its sole
and absolute discretion, that the Property is unsuitable for Buyer's needs, then
Buyer may terminate this Agreement by written notice to Seller given before the
closing date.

         (b) The Property is being sold and shall be conveyed and taken subject
to the following additional provisions:

a. SUBJECT TO any state of facts that an accurate survey and/or personal
inspection may show, provided such facts do not render title unmarketable.

b. SUBJECT TO covenants, restrictions, utility easements and consents, provided
that they are not violated by the existing structures and do not prohibit the
present use of such structures.

         (c) Seller has not made and does not make any representations as to the
physical condition (including but not limited to environmental matters) income,
expenses, operation or other matters or things on, affecting or relating to the
aforesaid premises, except as herein specifically set forth, and the Buyer
expressly acknowledges that no such representations have been made and the Buyer
further acknowledges that it has inspected the entire premises and agrees to
take the Property and each and every part thereof "as is", except as otherwise
specifically provided for herein.

         (d) Prior to the execution of the within contract, Purchasers represent
and warrant that they have been afforded full opportunity and access, to
conduct, a complete engineering, environmental and other inspections in, around,
and of the entire premises by engineers and/or contractors of their choice to
whatever extent they deemed necessary or desirable.

         4. Title. Title to the Property shall be fee simple, and conveyed by
bargain and sale deed with covenant against grantor's acts. If Buyer objects to
any condition of title, Seller shall use good faith efforts to cure such title
objection prior to the closing date. If Seller is unable to cure such title
objection, then Buyer may, by notice delivered to Seller prior to the closing
date, either (i) terminate this Agreement, in which case the parties shall have
no further liability to each other, or (ii) to waive any title objection which
is not so cured. Seller must pay off and discharge of records all liens
encumbering the Property at or prior to the closing, and Seller may use the
Purchase Price proceeds to pay same, provided that discharges of any liens, or
other evidence of satisfaction of same, satisfactory to Buyer's attorneys, are
delivered to Buyer at the closing.

         5. Seller's Representations and Warranties. Seller represents and
warrants to Buyer as follows:
