Plaintiff purchased a commercial condominium as an investment from defendants under a purchase agreement and at the same time entered into a management agreement under which one of the defendant companies would manage the condominium.  Only the management agreement contained an arbitration clause, and it was narrow, not broad, applying only to disputes arising in connection with the interpretation and enforcement of that agreement.  Though agreements signed at the same time are construed together, the separate agreements are not merged into each other.  So when plaintiff sued for fraud in connection with the purchase of the condominium, it was not required to arbitrate under the narrow arbitration clause in the separate management agreement.
