      All other terms remain unchanged. 

    


    CONTINUING
      VALIDITY.
      Except
      as expressly changed by this Agreement, the terms of the original obligation
      or
      obligations, including all agreements evidenced or securing the obligation(s),
      remain unchanged and in full force and effect. Consent by Lender to this
      Agreement does not waive Lender’s right to strict performance of the
      obligation(s) as changed, nor obligate Lender to make any future change in
      terms. Nothing in this Agreement will constitutes a satisfaction of the
      obligation(s). It is the intention of Lender to retain as liable parties all
      makers and endorsers of the original obligation(s), including accommodation
      parties, unless a party expressly released by Lender in writing. Any maker
      or
      endorser, including accommodation makers, will not be released by virtue of
      this
      Agreement. If any person who signed the original obligation does not sign this
      Agreement below, then all persons signing below acknowledge that this Agreement
      is given conditionally, based on the representation to Lender the non-signing
      party consents to the changes and provisions of this Agreement or otherwise
      will
      not be released by it. This waiver applies not only to any initial extension,
      modification or release, but also to all such subsequent actions.
