  contemplated  by  such  corporation  or  association  or  (b)  such real
  property is held by such corporation or association upon condition  that

  income is necessary for and is actually applied to the  maintenance  and
  support of such hospital.
    6. Such real property outside a city owned by a free public library or

  hundred eighty-three  owned  for  more  than  one  hundred  years  by  a
  corporation  organized exclusively for purposes specified in subdivision
  one of this section under a  grant  or  devise  and  a  special  charter
  granted  by  the  legislature  of  the  state  of  New  York  subject to
  conditions which raise doubt as to the  power  of  such  corporation  to
  convey  fee  title  to  the  property  shall,  if  the  property is used
  exclusively for educational purposes by an educational corporation which
  owns real property exempt from taxation, or whose real  property  if  it
  owned  any  would  be  exempt from taxation, as lessee for a term of not
  less than twenty-five years and if such lease  were  in  effect  on  the
  first  day  of  January,  nineteen hundred eighty-three and requires the
  lessee to pay all taxes levied against  the  property,  be  exempt  from
  taxation  to  the  same  extent  and  subject to the same conditions and
  exceptions as property owned and used  for  educational  purposes  by  a

  state, by a municipal corporation  for  a  public  use,  or  by  or  for
  not-for-profit organizations.
    10. Real property, which on the first day of January, nineteen hundred
  ninety  was  exempt from real property taxation pursuant to this section

  organized  exclusively for educational purposes, and which the fee title
  to such property is conveyed prior to June thirtieth,  nineteen  hundred
  ninety-one  to  a  governmental  entity,  shall be exempt from taxation;

  educational corporation whose real property, when used  for  educational
  purposes,  is exempt from taxation, and (b) such property shall continue

    11.  An  exemption  may  be  granted  pursuant  to  this  section upon
  application by the owner on a form prescribed by the state board or  any
  comparable form, which application may be filed with the assessor of the

  appropriate  county,  city,  town or village on or before the applicable
  taxable status date. Where the assessor receives  no  such  application,
  the  assessor may nevertheless grant the exemption provided the assessor
  personally  inspects  the  property  and  certifies  in  writing that it
  satisfies all of the  requirements  for  exemption  set  forth  in  this
  section.  Where  property  is  not granted an exemption pursuant to this
  section, the owner may seek judicial review pursuant to article seven of
  this chapter or article seventy-eight of  the  civil  practice  law  and
  rules.

  corporation or  association  and  ending  on  June  thirtieth,  nineteen
  hundred  ninety-five,  shall  be exempt from taxation for such period as

  real  property  taxes and interest thereon that accrued on such property
  prior to the date on which the fee title to such property  was  acquired

  contrary,  such  agreement  may  require  that payment of such taxes and
  interest thereon be made in quarterly installments over a period not  to
  exceed thirty years.
