  Sec 128     -    
  
  Particulars in case of series of debentures entitling holders pari passu. 
  Where a series of debentures containing, or giving by reference
  
  to any other instrument, any charge to the benefit of which debenture holders
  
  of that series are entitled pari passu is created by a company, it shall, for
  
  the purposes of section 125, be sufficient, if there are filed with the
  
  Registrar, within thirty days after the execution of the deed containing the
  
  charge or, if there is no such deed, after the execution of any debentures of
  
  the series, the following particulars :
  (a) the total amount secured by the whole
  
  series ;
  (b) the dates of the resolutions authorizing
  
  the issue of the series and the date of the covering deed, if any, by which the
  
  security is created or defined ;
  (c) a general description of the property
  
  charged ; and
  (d) the names of the trustees, if any, for the
  
  debenture holders ;
  together with the deed containing the charge, or a copy of the
  
  deed verified in the prescribed manner, or if there is no such deed, one of the
  
  debentures of the series :
  Provided  that, where more than one issue is made of
  
  debentures in the series, there shall be filed with the Registrar, for entry in
  
  the register, particulars of the date and amount of each issue ; but an
  
  omission to do this shall not affect the validity of the debentures issued.
