<xdr:twoCellAnchor>
  <xdr:from>
    <xdr:col>3</xdr:col>
    <xdr:colOff>447675</xdr:colOff>
    <xdr:row>8</xdr:row>
    <xdr:rowOff>28575</xdr:rowOff>
  </xdr:from>
  <xdr:to>
    <xdr:col>5</xdr:col>
    <xdr:colOff>466725</xdr:colOff>
    <xdr:row>14</xdr:row>
    <xdr:rowOff>9525</xdr:rowOff>
  </xdr:to>
  <xdr:sp macro="" textlink="">
  …
  </xdr:sp>
  <xdr:clientData/>
</xdr:twoCellAnchor>
