RIGHT OF FIRST REFUSAL AGREEMENT

        RIGHT OF FIRST REFUSAL AGREEMENT (this "Agreement") executed on this
19th day of November, 2003, and effective as of this 9th day of December, 2003,
by and among Welsh-Square, Inc., a Pennsylvania corporation ("WSI"), Indenture
of Trust of Bart Blatstein dated as of June 9, 1998, a Pennsylvania trust ("1998
Trust") and Irrevocable Indenture of Trust of Barton Blatstein dated July 13,
1999, a Pennsylvania trust ("1999 Trust"; and together with WSI and 1998 Trust,
collectively, the "Owners") and Delaware 1851 Associates, L.P., a Pennsylvania
Limited Partnership (the "Partnership").

                                   WITNESSETH

        WHEREAS, the Partnership is the owner of the property described in
Exhibit A annexed hereto.

        WHEREAS, the Owners desire that the Partnership grant the First Refusal
Option (as that term is hereinafter defined).

        WHEREAS, the Partnership is willing to grant to the Owners the First
Refusal Option.

        NOW, THEREFORE, in consideration of the foregoing and the mutual
covenants and agreements herein contained, the parties hereto covenant and agree
as follows:

        1.      Subject to the terms of this Agreement, the Partnership agrees
that if any time the Partnership shall receive a bona fide written offer (an
"Offer") for the purchase of all or any portion of the Property which the
Partnership proposes to accept, the Partnership shall, within five (5) days of
the date of receipt of such Offer, give prompt written notice thereof to the
Owners (the "First Refusal Notice"). The First Refusal Notice shall set forth
the material terms and conditions of the Offer, including, the closing date, the
sales price, the down payment, the timing of payment, any financing contingency,
and any due diligence period, together with the permitted encumbrances which the
proposed purchaser is required to accept. The Owners shall have the option (the
"First Refusal Option") to purchase the Property strictly on the same terms and
conditions set forth in the First Refusal Notice. Such First Refusal Option
shall be exercisable by the Owner's (a "First Refusal Exercise Notice")
delivered to the Partnership not later than the tenth (10th) Business Day (the
"First Refusal Exercise Notice Date") following the date that such First Refusal
Notice is received by the Owners. Time is of the essence with respect to the
Owner's giving of the First Refusal Exercise Notice to the Partnership. The
First Refusal Option shall be exercisable by the Owners in accordance with, and
shall be subject to and governed by, the terms, covenants and conditions
contained in this Paragraph 1. The closing of any sale to the Owners shall occur
on the date (the "First Refusal Closing Date") that is the later to occur of (x)
the closing date set forth in the First Refusal Notice and (y) thirty (30) days
after the date of delivery by the Owners of the First Refusal Exercise Notice.
If the Owners shall timely and properly give a First Refusal Exercise Notice to
the Partnership, the parties shall proceed in good faith and with due diligence
to enter into documentation necessary to consummate the sale of the Property
which shall reflect the terms of the Offer set forth in such First Refusal
Notice, together with other commercially reasonable terms. If the parties shall
fail



to enter into such documentation by the First Refusal Closing Date, the Owners'
First Refusal Exercise Notice shall be deemed to be revoked.

        2.      If the Owners fail to give a First Refusal Exercise Notice to
the Partnership on or before the respective First Refusal Exercise Notice Date
or the Owners shall elect not to accept the Offer set forth in the respective
First Refusal Notice on or before such First Refusal Exercise Notice Date or the
Owners' First Refusal Exercise Notice shall be deemed to be revoked (as
contemplated by the last sentence of Paragraph 1), then the First Refusal Option
shall be deemed revoked, null and void, and of no further force and effect, and
the Partnership may thereafter proceed with the sale of the Property so long as
the purchase price for such sale is at least ninety fie (95%) percent of the
purchase price set forth in the First Refusal Notice; provided however, if the
Partnership shall fail to close such transaction within ten (10) months after
the respective First Refusal Exercise Notice Date, then the Owners' First
Refusal Option shall continue to apply to any subsequent availability for sale
of the Property.

        3.      If the Owners shall timely and properly give a First Refusal
Exercise Notice to the Partnership, and the parties shall timely enter into
documentation necessary to consummate the sale of the Property, but the closing
shall fail to occur due to a default by the Owners, then the First Refusal
Option shall be deemed permanently revoked, null and void, and of no further
force or effect.

        4.      This Agreement shall automatically terminate upon the earlier of
(i) the date which is ten (10) years from the date hereof, and (ii) the
nullification of the First Refusal Option pursuant to Section 3. Notwithstanding
such automatic termination, the Owners shall, upon the termination of this
Agreement, execute and deliver a document, in form suitable for recording,
terminating all of its right, title, and interest in and to the First Refusal
Option, and, if the Owners fail to do so within twenty (20) days following the
date of such termination, the Owners shall be deemed to have designated a power
of attorney to the Partnership to execute such termination on the Owners behalf.

        5.      Notices. Any notice required or permitted to be delivered herein
shall be deemed to be delivered (a) when received by the addressee if delivered
by courier service, (b) if mailed, two days after deposit in the United States
Mail, postage prepaid, certified mail, return receipt requested, (c) if sent by
recognized overnight service (such as US Express Mail, Federal Express, UPS,
Airborne, etc.), then one day after delivery of same to an authorized
representative or agency of the said overnight service or (d) if sent by a
telecopier, when transmission is received by the addressee with electronic or
