         3.1.2    Borrower has not changed its name, form, or structure, been
                  the surviving entity in a merger or acquired any business; or

                  Inventory.
         3.1.3    This Agreement and any other Loan Documents constitute valid
                  and legally binding Obligations of Borrower and are
                  enforceable against Borrower in accordance with their
                  respective terms.
         3.1.4    Borrower has filed all Federal, state and local tax returns
                  and other reports it is required to file and has paid or made

                  and other governmental charges.

         3.1.5    All property owned or utilized by Borrower is in compliance
                  and will continue to be in compliance with all requirements of
                  all applicable environmental laws, including, without
                  limitation, the Industrial Site Recovery Act f/k/a the
                  Environmental Cleanup Responsibility Act (N.J.S.A. 13:1K-6 et

                  (N.J.S.A. 58:10-23.11 as amended) and a certain statute
                  adopted by New Jersey for registration of underground storage
                  tanks (N.J.S.A. 58:10A-21 et seq.); the Hazardous and Solid
                  Waste Amendments of 1984 Pub. L98-616 (42 U.S.C. 699 et seq.,

                  hereinafter collectively referred to as the "Environmental
                  Laws").
         3.1.6    Borrower has good and marketable title to all of its
                  properties and assets. The execution and performance of this
                  Agreement and any Loan Document will not violate or result in
                  a default or in the creation or imposition of any lien or
                  encumbrance upon any of the assets of Borrower (immediately,
                  with the passage of time or with the giving of notice and the
                  passage of time) under any other contract, agreement or
                  instrument to which Borrower is a party or by which Borrower
                  is bound, nor will it result in the acceleration of any
                  obligation under any mortgage, lien, lease, franchise,
                  license, permit, agreement, instrument, order, arbitration
                  award, judgment, or decree, or in the termination of any
                  license, franchise, lease, or permit to which Borrower is a
                  party or by which it is bound; and it will not violate or
                  conflict with any other restriction of any kind or character
                  to which Borrower is subject.

                  personal, household or family purposes.

                  proceeding whether or not pending, threatened or imminent
                  against or otherwise affecting Borrower that involves the
                  possibility of any judgment or liability not fully covered by
                  insurance or that may result in a material adverse change in
                  the business, properties, prospects, operation or condition
                  (financial or otherwise) of Borrower.
         3.1.9    Borrower has complied with all applicable statutes,
                  regulations, ordinances, court decrees or other directives of
                  the United States of America, and all states, counties,

                  and sale of its goods, the rendition of its services and/or
                  the conduct of its business.
         3.1.10   Borrower has heretofore delivered to Bank current financial
                  statements, acceptable to Bank, which were prepared by
                  independent certified public accountants. The financial
                  statements were true, correct and complete and were prepared
                  in accordance with Generally Accepted Accounting Principles,
                  consistently applied and present fairly the financial position
                  and results of operations of Borrower as of the date of and
                  for the period involved. The financial statements make full
                  and adequate provision for all obligations, liabilities, and
                  commitments (fixed and contingent) of Borrower as of the date
                  of the financial statements. Since the date of the financial
                  statements, there has been no material adverse change in the
                  business, properties, prospects, operation or condition
                  (financial or otherwise) of Borrower.
         3.1.11   With respect to each Employee Benefit Plan maintained by
                  Borrower, no Prohibited Transaction or Reportable Event (as
                  defined in Title IV of the Employee Retirement Income Security

                  Pension Benefit Guaranty Corporation, and Borrower will comply
                  with the provisions of the Employee Retirement Income Security
                  Act of 1974, as amended and the Internal Revenue Code of 1986,
                  as amended.
         3.1.12   Borrower is the owner of the Collateral free and clear of all
                  Security Interests, encumbrances or liens, except liens which
                  arise by operation of law with respect to Obligations of
                  Borrower which are not yet due and payable; and Borrower will
                  defend the Collateral against all claims and demands of all
                  persons or entities at any time claiming an interest therein.

                  interpretation thereof, or any change in any of the foregoing,
                  has or would have the effect of reducing the rate of return on
                  Bank's capital as a consequence of Bank's obligations under
                  this Agreement to a level below that which Bank would have
                  achieved but for such law, regulation, condition, directive,
                  interpretation or change (taking into consideration Bank's
                  policies with respect to capital adequacy) by an amount deemed
                  by Bank to be material, then from time to time Borrower shall
                  pay to Bank on demand such additional amount(s) as will
                  compensate Bank for such reduction.

         7.5.1    Bank will promptly notify Borrower of any event of which it
                  has knowledge, occurring after the date hereof, which will
                  entitle Bank to compensation pursuant to Section 7.5. A
                  certificate or notice from Bank claiming compensation under
                  Section 7.5 and setting forth the additional amount(s) to be
                  paid to it hereunder shall be conclusive in the absence of
                  manifest error. In determining such amount, Bank may use any
                  reasonable averaging and attribution methods.
         7.5.2    Borrower's failure to pay such additional amount(s), shall
                  result in Borrower becoming liable for the difference between
                  the actual return achieved and what Bank had expected to
                  achieve and shall become a part of Borrower's Obligations
                  herein secured by the Collateral.
         7.6      In the event that Borrower's credit relationship with Bank is
                  rated substandard or lower on Bank's rating system(s), all of
                  which ratings shall be in Bank's absolute and sole discretion,
                  Borrower shall pay to Bank, upon receipt of notice from Bank
                  to such effect, an additional 1% per annum in excess of each
                  payment to be made under this Agreement and any other Loan
                  Document until such rating is upgraded to above substandard.
                  Borrower's failure to pay such additional amount(s) shall
                  become a part of Borrower's Obligations payable on demand and
                  secured by the Collateral.

8.       GENERAL PROVISIONS

         8.1      The failure of Bank at any time or times hereafter to require
                  strict performance by Borrower of any of the provisions,
                  warranties, terms and conditions contained herein or in any
                  Loan Document shall not waive, affect or diminish any right of
                  Bank at any time or times thereafter to demand strict
                  performance thereof. No rights of Bank hereunder or in any
                  Loan Document shall be deemed to have been waived by any act
                  or knowledge of Bank, its agents, officers or employees,
                  unless such waiver is contained in an instrument in writing
                  signed by an officer of Bank and directed to Borrower
                  specifying such waiver. No waiver by Bank of any of its rights
                  shall operate as a waiver of any other of its rights or any of
                  its rights on a future occasion.
         8.2      Any demand or notice required or permitted to be given
                  hereunder or in any Loan Document shall be deemed effective
                  when deposited in the United States mail, and sent by
                  certified mail, return receipt requested, postage prepaid,
                  addressed to Bank, ATTN: Branch Manager, at Bank's Address or
                  to Borrower at Borrower's Address, as applicable, or to such
                  other address as may be provided by the party to be notified,
                  on ten (10) days prior written notice to the other party.
         8.3      Any notice required to be given by Bank made in accordance
                  with the terms herein or any Loan Document at least ten (10)
                  days prior to such proposed action, shall constitute fair and
                  reasonable notice to Borrower of any such action.
         8.4      This Agreement and the Loan Documents contain the entire
                  understanding between the parties hereto with respect to the
                  transactions contemplated herein and such understanding shall
                  not be modified except in writing signed by or on behalf of
                  the parties hereto.
         8.5      Borrower shall not hold Bank liable due to any action or
                  failure to act by Bank herein or in any Loan Document except
                  for any action or failure to act as a result of Bank's gross
                  negligence or willful misconduct. This provision shall survive
                  the termination or expiration of this Agreement or any Loan
                  Document and the repayment in full of Borrower's Obligations.
         8.6      Wherever possible, each provision herein or in any Loan
                  Document shall be interpreted in such manner as to be
                  effective and valid under applicable law. Should any portion
                  of this Agreement or any Loan Document be declared invalid for
                  any reason in any jurisdiction, such declaration shall have no
                  effect upon the remaining portions of this Agreement or any
                  Loan Document. Furthermore, the entirety of this Agreement or
                  any Loan Document shall continue in full force and effect in
                  all other jurisdictions and said remaining portions herein or
                  in any Loan Document shall continue in full force and effect
                  in the subject jurisdiction as if this Agreement or any Loan
                  Document had been executed with the invalid portions thereof
                  deleted.

         8.7      In the event Bank seeks to take possession of any or all of
                  the Collateral by court process, Borrower hereby irrevocably
                  waives any bonds and any surety or security relating thereto
                  required by any statute, court rule or otherwise as an
                  incident to such possession, and waives any demand for
                  possession prior to the commencement of any suit or action to
                  recover.
         8.8      The provisions of this Agreement or any Loan Document shall be
                  binding upon and shall inure to the benefit of the heirs,
                  personal representatives, administrators, successors and
                  assigns of Bank and Borrower; provided, however, Borrower may
                  not assign any of its rights or delegate any of its
                  Obligations hereunder or in any Loan Document without the
                  prior written consent of Bank.
         8.9      This Agreement or any Loan Document is and shall be deemed to
                  be a contract entered into and made pursuant to the laws of
                  the State of New Jersey and shall in all respects be governed,
                  construed, applied and enforced in accordance with the laws of
                  said State.
         8.10     If, prior hereto and/or at any time or times hereafter, Bank
                  shall employ counsel in connection with the execution and
                  consummation of the transactions contemplated herein or in any
                  Loan Document or to commence, defend or intervene, file a
                  petition, complaint, answer, motion or other pleadings, or to
                  take any other action in or with respect to any suit or
                  proceeding (bankruptcy or otherwise) relating to this
                  Agreement or any Loan Document, or to enforce any rights of
                  Bank hereunder or in any Loan Document, whether before or
                  after the occurrence of any Event of Default, or to collect
                  any of the Obligations then, in any of such events, Borrower
                  agrees to pay attorney fees, (whether or not such attorney is
                  a regularly salaried employee of Bank, any parent corporation
                  or any subsidiary or affiliate thereof, whether now existing
                  or hereafter created), not to exceed 20% of the Obligations,
                  which shall be deemed reasonable and any expenses, costs and
                  charges relating thereto, and such shall be part of the
                  Obligations payable on demand and secured by the Collateral.
         8.11     With respect to all or any part of the Obligations, in the
                  event that Bank seeks to enter into a participation,
                  intercreditor and/or assignment agreement, then Borrower
                  hereby authorizes Bank to release all or part of any financial
                  or credit information provided by Borrower to Bank to any
                  other bank or financial institution without notice.
         8.12     Each reference herein or in any Loan Document to Bank shall be
                  deemed to include its successors and assigns, and each
                  reference to Borrower and any pronouns referring thereto as
                  used herein shall be construed in the masculine, feminine,
                  neuter, singular or plural as the context may require, and
                  shall be deemed to include the heirs, personal
                  representatives, administrators, successors and assigns of
                  Borrower, all of whom shall be bound by the provisions hereof
                  or in any Loan Document. The term "Borrower" as used herein
                  shall, if this Agreement or any Loan Document is signed by
                  more than one Borrower, mean, unless this Agreement or any
                  Loan Document otherwise provides or unless the context
                  otherwise requires, the "Borrower" and each of them and each
                  and every representation, promise, agreement and undertaking
                  shall be joint and several, except that the granting of the
                  Security Interest, right of set-off and lien shall be by each
                  Borrower in and to its several respective properties.
         8.13     The section headings herein are included for convenience only
                  and shall not be deemed to be a part of this Agreement or any
                  Loan Document.

9.       ASSIGNMENT BY BANK

         Bank may from time to time without notice to Borrower, sell, assign,
         transfer or otherwise dispose of all or any part of the Obligations
         and/or the Collateral therefor. In such event, each and every immediate
         and successive purchaser, assignee, transferee or holder of all or any
         part of the Obligations and/or the Collateral therefor shall have the
         right to enforce this Agreement, by legal action or otherwise, for its
         own benefit as fully as if such purchaser, assignee, transferee or
         holder were herein by name specifically given such rights. Bank shall
         have an unimpaired right to enforce this Agreement for its benefit to
         that portion of the Obligations as Bank has not sold, assigned,
         transferred or otherwise disposed of.
