11 U.S.C. § 1222 : US Code - Section 1222: Contents of plan

      (a) The plan shall - 
        (1) provide for the submission of all or such portion of future
      earnings or other future income of the debtor to the supervision
      and control of the trustee as is necessary for the execution of
      the plan;
        (2) provide for the full payment, in deferred cash payments, of
      all claims entitled to priority under section 507, unless - 
          (A) the claim is a claim owed to a governmental unit that
        arises as a result of the sale, transfer, exchange, or other
        disposition of any farm asset used in the debtor's farming
        operation, in which case the claim shall be treated as an
        unsecured claim that is not entitled to priority under section
        507, but the debt shall be treated in such manner only if the
        debtor receives a discharge; or
          (B) the holder of a particular claim agrees to a different
        treatment of that claim;

        (3) if the plan classifies claims and interests, provide the
      same treatment for each claim or interest within a particular
      class unless the holder of a particular claim or interest agrees
      to less favorable treatment; and
        (4) notwithstanding any other provision of this section, a plan
      may provide for less than full payment of all amounts owed for a
      claim entitled to priority under section 507(a)(1)(B) only if the
      plan provides that all of the debtor's projected disposable
      income for a 5-year period beginning on the date that the first
      payment is due under the plan will be applied to make payments
      under the plan.

      (b) Subject to subsections (a) and (c) of this section, the plan
    may - 
        (1) designate a class or classes of unsecured claims, as
      provided in section 1122 of this title, but may not discriminate
      unfairly against any class so designated; however, such plan may
      treat claims for a consumer debt of the debtor if an individual
      is liable on such consumer debt with the debtor differently than
      other unsecured claims;
        (2) modify the rights of holders of secured claims, or of
      holders of unsecured claims, or leave unaffected the rights of
      holders of any class of claims;
        (3) provide for the curing or waiving of any default;
        (4) provide for payments on any unsecured claim to be made
      concurrently with payments on any secured claim or any other
      unsecured claim;
        (5) provide for the curing of any default within a reasonable
      time and maintenance of payments while the case is pending on any
      unsecured claim or secured claim on which the last payment is due
      after the date on which the final payment under the plan is due;
        (6) subject to section 365 of this title, provide for the
      assumption, rejection, or assignment of any executory contract or
      unexpired lease of the debtor not previously rejected under such
      section;
        (7) provide for the payment of all or part of a claim against
      the debtor from property of the estate or property of the debtor;
        (8) provide for the sale of all or any part of the property of
      the estate or the distribution of all or any part of the property
      of the estate among those having an interest in such property;
        (9) provide for payment of allowed secured claims consistent
      with section 1225(a)(5) of this title, over a period exceeding
      the period permitted under section 1222(c);
        (10) provide for the vesting of property of the estate, on
      confirmation of the plan or at a later time, in the debtor or in
      any other entity;
        (11) provide for the payment of interest accruing after the
      date of the filing of the petition on unsecured claims that are
      nondischargeable under section 1228(a), except that such interest
      may be paid only to the extent that the debtor has disposable
      income available to pay such interest after making provision for
      full payment of all allowed claims; and
        (12) include any other appropriate provision not inconsistent
      with this title.

      (c) Except as provided in subsections (b)(5) and (b)(9), the plan
    may not provide for payments over a period that is longer than
    three years unless the court for cause approves a longer period,
    but the court may not approve a period that is longer than five
    years.
      (d) Notwithstanding subsection (b)(2) of this section and
    sections 506(b) and 1225(a)(5) of this title, if it is proposed in
    a plan to cure a default, the amount necessary to cure the default,
    shall be determined in accordance with the underlying agreement and
    applicable nonbankruptcy law.
