Shortfall to Roberts, and Purchaser shall pay to Roberts by check from the
Escrowed Funds within five business days after the inventory is completed an
amount equal to $300,000 less the Material Shortfall.  In the event Roberts

firm.  In the event that the Adjusted Material Shortfall is more than the
Material Shortfall, Roberts shall pay to Purchaser the amount of the difference
between the Material Shortfall and the Adjusted Material Shortfall by check
within five business days of receiving notice of the Adjusted Material Shortfall
by the accounting firm.  The balance of the Escrowed Funds shall be paid to
Purchaser or its designee if Roberts does not notify Purchaser of its
disagreement with respect to Purchaser's calculation of the Material Shortfall
within the ten business day period described above, or upon payment to Roberts
of any amount due based on the determination of the Adjusted Material Shortfall
by the accounting firm as described above.

              REPRESENTATIONS AND WARRANTIES OF ROBERTS' AND PHCG
              ---------------------------------------------------

         Roberts and PHCG each hereby represents and warrants to Purchaser and
Parent as follows:

     SECTION 5.01.  CORPORATE STATUS.

     Roberts is a corporation duly organized, validly existing, and in good

and New Jersey (in the case of PHCG New Jersey), and each has the requisite
corporate power and authority to own or lease their respective Assets and to
operate the Business in their respective jurisdictions of incorporation. Each of
PHCG New Jersey and PHCG New York is duly qualified or licensed to do business

character of property owned or leased or the nature of the activities conducted
by it makes such qualification or licensure necessary.

     SECTION 5.02.  AUTHORITY AND APPROVAL.
                    ---------------------- 

     Each of Roberts and PHCG has full power and authority to enter into this
Agreement and to assume and perform its obligations hereunder.  This Agreement
and the agreements and transactions contemplated hereby have been approved and
authorized by the Boards of Directors of Roberts and PHCG, and constitute valid,
binding and enforceable obligations of Roberts and PHCG, except to the extent
the enforceability thereof may be limited by applicable bankruptcy, insolvency,
reorganization, equitable principles or similar laws affecting legal or
equitable rights generally.  No action, approval, consent or authorization with
respect to Roberts is required, which has not already been taken or obtained, in
order to constitute this Agreement as a binding and enforceable obligation of
Roberts and PHCG in accordance with its terms.

     SECTION 5.03.  NO VIOLATION.
                    -------------

                                       15
<PAGE>
 
     Neither the execution and delivery of this Agreement by Roberts and PHCG,
nor the performance of Roberts' and PHCG's obligations hereunder, will violate,
conflict with, or constitute a default under, any of the terms of the
Certificates or Articles of Incorporation or by-laws of Roberts, PHCG New Jersey
or PHCG New York, or any provisions thereof, or result in the acceleration of
any obligation under any contract, sales commitment, license, purchase order,
security agreement, mortgage, note, deed, lien, lease, agreement, instrument,
order, judgment or decree to which Roberts, PHCG New Jersey or PHCG New York is
a party or by which Roberts, PHCG New Jersey, PHCG New York, the Premises, or
the Assets are bound, and will not constitute an event which, after the giving
of notice or lapse of time or both, will result in such violation, conflict,
default or acceleration.  The execution and delivery of this Agreement and the
performance by Roberts and PHCG of the transactions contemplated hereby will not
result in the creation or imposition of any Encumbrances in favor of any third
person or entity upon the Premises or the Assets and will not violate any law,
judgment, decree, order, rule or regulation of any Governmental Authority
applicable to Roberts, PHCG New Jersey, PHCG New York, the Premises, or the
Assets.

     SECTION 5.04.  TITLE.
                    ----- 

     PHCG is the owner of and has good and marketable title to the Assets, free
and clear of any and all Encumbrances, except as expressly set forth on Schedule
                                                                        --------
H and as contemplated in Section 2.02 above with respect to the Premises.

     SECTION 5.05.  CONTRACTS AND COMMITMENTS.
                    ------------------------- 

     Each of the Contracts, the Personal Property Leases and the Real Property
Leases is a valid and binding agreement, enforceable according to its terms and

full through the end of the calendar month in which the First Closing Date
occurs.  Neither PHCG nor Roberts has breached or terminated or is in default
under any of the Contracts, the Personal Property Leases or the Real Property
Leases and there exists no condition or event which, after notice or lapse of
time or both, would constitute any such breach, termination or default.  To the
best of Roberts' and PHCG's knowledge and belief, no other party to any such
Contract, Personal Property Lease or Real Property Lease has breached,
terminated or is in default under such Contract, Personal Property Lease or Real
Property Lease, and there exists no condition or event which, after notice or
lapse of time or both, would constitute any such breach, termination, or
default.

no consent of any party is required under any document listed on Schedules A, D
                                                                 -----------  -

this Agreement or any agreement entered into in connection herewith.  The
consummation of the transactions contemplated by this Agreement or any agreement
executed in connection herewith will not violate the terms or provisions of any
agreement to which PHCG is a party, cause the acceleration of the maturity of
any debt or obligation of PHCG or result in the creation or imposition of any
Encumbrance upon any of the Assets.

                    --------------------

deal in any of its products and services and no individual or entity will have a
valid basis for any claimed right to interfere (by way of legal action, oral or

administrative agency or the like) with the exercise by PHCG of such rights or
any other rights hereunder or in connection with the Business.  Except for
obligations or agreements set forth on Schedule L, PHCG is not obligated to any

neither Roberts nor PHCG has received notice of cancellation thereof and Roberts
and PHCG will each use their best respective efforts to keep such issuers from

     SECTION 5.21.  CUSTOMERS AND SUPPLIERS.
                    ------------------------

     Schedule O sets forth a true and complete list of all customers of PHCG as
     ----------                                                                
well as a true and complete list of all suppliers of PHCG.  Neither Roberts nor
PHCG has any knowledge that any material customer or material supplier has
terminated or expects to terminate any portion of its, his or her business with
PHCG.  No customer has refused to honor any of its commitments to PHCG nor has
any customer expressed material dissatisfaction with the nature or the quality
of any services or products nor has there been any material adverse change in
the relationships of PHCG with any of its customers since December 31, 1995.

     SECTION 5.22.  ENVIRONMENTAL CLAIMS.
                    -------------------- 

     Neither Roberts nor PHCG has received any notification that PHCG is in
violation of, nor is PHCG in material violation of, any law, regulation, permit,
license or other authorization with respect to any Federal, State or local law
or regulation regulating pollution or the protection of the environment.  There
are no environmental conditions existing at any facility operated in connection
with the Business which reasonably could be expected to give rise to common law
or statutory liability for damages or injunctive relief against PHCG.  No
premises owned or leased by PHCG contain any hazardous substance (as defined
below) other

                                       21

than those required to conduct the Business in the ordinary course which are
used and stored in compliance with all applicable laws;  PHCG has not conducted
or authorized the generation, transportation, storage, treatment or disposal of
any hazardous substance other than that required in the ordinary course of the
Business.  There is no pending or, to the knowledge of Roberts or PHCG,
threatened litigation or proceedings before any Governmental Authority in which
any Person alleges the presence, release, threat of release, placement on or in
the Premises or any real property leased by PHCG, or the generation,
transportation, storage, treatment or disposal on or in any such premises, of
any hazardous substance.  No Governmental Authority or any employee or agent
thereof has determined, or, to the knowledge of Roberts or PHCG, threatens to
determine, that there is a presence, release, threat of release, placement on or
in the Premises or any real property leased by PHCG, or the generation,
transportation, storage, treatment, or disposal at such premises, of any
hazardous substance.  There have been no communications or agreements with any
Governmental Authority or any private entity, including, but not limited to, any
prior owners of the Premises or any real property leased by PHCG, relating in
any way to the presence, release, placement on or in such premises, or the
generation, transportation, storage or treatment or disposal at such premises,
of any hazardous substance.  For purposes of this Section 5.22, "hazardous
substance" means any matter giving rise to liability under the Resources
Conversation Recovery Act, 42 U.S.C. Sections 6901 et seq., the Comprehensive
                                                   -- ----

or any applicable laws or regulations of the States of New Jersey or New York,
or any agency or department thereof, or any common law theory based on nuisance
or strict liability.

     SECTION 5.23.  NO MATERIAL OMISSIONS.
                    --------------------- 

     Neither Roberts nor PHCG knows of any material facts or circumstances not
disclosed to Purchaser which should be disclosed to Purchaser in order to make
any of the representations or warranties made herein not misleading.  The copies
of all instruments, agreements, other documents and written information referred
to in this Agreement and the Schedules are complete and correct in all material
respects as of the date hereof.  No representation or warranty by Roberts or
PHCG in this Agreement and no statement contained in any document, certificate
or other writing furnished or to be furnished by Roberts and PHCG to Purchaser
pursuant to the provisions hereof, when all such documents are taken as a whole,
contains or will contain any untrue statement of material fact or omit or will
omit to state any material fact necessary in order to make the statements herein
or therein not misleading.

mortgage, note, deed, lien, lease, agreement, instrument, order, judgment or
decree to which Purchaser or Parent is a party or by which Purchaser or Parent
is bound, and will not constitute an event which, after notice or lapse of time

execution and delivery of this Agreement and the performance by Purchaser and
Parent of the transactions contemplated hereby will not violate any law,
judgment, decree, order, rule or regulation of any Governmental Authority
