An Owner is entitled to a see a copy of the Agreement – he/she can formally request it from the Managing Agent as part of an inspection of the Strata documents upon payment of a fee as prescribed.  Informally he/she can approach the Secretary to see it.  I would expect that an Executive Committee member would have access to a copy from the same source.  The Agreement is between the Managing Agency and the Strata Scheme, so each party should retain a copy of the agreement.
