1.   Provisions Concerning Deferred Interest.
     ----------------------------------------

     1.1.  Option of the  Companies to  Capitalize  a Portion of  Interest.  The
           ----------------------------------------------------------------
Companies may, at their option (upon notice as provided in section 1.2), in lieu
of paying cash,  defer the payment of up to 2/14th (or  14.28571%) of the amount
of  interest  which is due and payable on this Note on any  regularly  scheduled
interest  payment date (the  portion of interest  that is not so paid in cash on
any regularly  scheduled interest payment date being hereinafter  referred to as
the "Deferred Interest") until maturity (whether by declaration, acceleration or
otherwise).  Such  Deferred  Interest  shall be  deemed  to be  included  in the
principal amount of this Note, as of such regularly  scheduled  interest payment
date  (any  such  date on and as of which  the  interest  is  deferred  shall be
referred to as an "Adjustment  Date"),  provided that (a) the Companies exercise
                                        --------       -
such option  proportionately  with respect to all of the Notes then  outstanding
and (b) on such regularly  scheduled interest payment date, the Companies pay in
     -
cash in full all interest (other than interest that is deferred pursuant to this
section  1) which  is due and  payable  on such  date on all of the  Notes  then
outstanding.  If the  Companies  shall,  in  accordance  with the  terms of this
section 1, exercise such option,  then, from and after each Adjustment Date, the
Deferred Interest shall be treated as if it were part of the principal amount of
each Note.

     1.2.  Notice from the Companies.  To exercise the option under section 1.1,
           --------------------------
the Companies  shall deliver to each holder of any Note not less than 10 or more
than 30 days prior to an Adjustment Date, an Officer's  Certificate  which shall
specify:

          (a) the applicable Adjustment Date;

          (b) (i) the portion of the  interest  which is due and payable on such
               -
     Adjustment Date on the Notes to be treated as Deferred  Interest,  (ii) the
                                                                         --
     aggregate  amount of Deferred  Interest to be treated as of such Adjustment
     Date as part of the  principal  amount of the Notes  then  outstanding  and
     (iii) the amount of Deferred  Interest to be treated as of such  Adjustment
      ---
     Date as if it were part of the  principal  amount of each Note then held by
     such holder;

          (c)  the  aggregate  amount  of  interest  to be  paid in cash on such
     Adjustment  Date on all of the Notes  then  outstanding  and the  amount of
     interest to be paid in cash on such  Adjustment  Date with  respect to each
     Note then held by such holder;

          (d) the aggregate  principal amount and deferred interest of the Notes
     then  outstanding  and the principal  amount and deferred  interest of each
     Note then held by such  holder,  in each case both before and after  giving
     effect to the adjustments to be made as of such Adjustment Date;

                                  Exhibit 1(a)
                                  ------------

                                      -3-


          (e) the aggregate  amount of each  interest  payment to be made on and
     after such  Adjustment  Date on all of the Notes then  outstanding (if paid
     entirely in cash) and the amount of each such interest payment on each Note
     then held by such holder; and

          (f) in reasonable  detail,  all  computations  made in determining the
     foregoing.

In the absence of manifest error,  the  computations set forth in such Officer's
Certificate  shall be deemed final binding and conclusive upon the Companies and
the holders of the Notes, unless, in any case, the Required Holders of the Notes
shall notify the Companies in writing of their objection (in reasonable  detail)
to any  portion of such  Officer's  Certificate  within 30 days of the date upon
which such Officer's  Certificate  was furnished to the holders of the Notes. In
such event,  the  Companies  shall,  at their  expense,  within 15 Business Days
following the receipt of any such notice from the Required Holders of the Notes,
deliver  to  the  holders  of the  Notes  a  certificate  signed  by a  firm  of
independent  certified public accountants of recognized national standing (which
may be the  regular  auditors of the  Companies),  setting  forth in  reasonable
detail any adjustments which, in the opinion of such accountants, should be made
to the amounts set forth in such Officer's Certificate in order for such amounts
to be correct and  consistent  with the terms hereof and of the other  Operative
Documents and, in reasonable  detail,  all computations  made in determining any
such  adjustments.  The  certificate  of any such firm of  accountants  shall be
conclusive evidence of the correctness of such amounts under this section 1.2.

     1.3  Limitations  on the Option of the  Companies to  Capitalize  Interest.
          ----------------------------------------------------------------------
Notwithstanding  anything  to the  contrary  contained  in this  section  1, the
Companies may not defer any interest  pursuant to the provisions of this section
1 on any  Adjustment  Date if on such  Adjustment  Date any  Default or Event of
Default shall have occurred and be continuing.

Subordinated  Indebtedness  or to comply with any of the terms and conditions of
any  of  the  agreements,  documents  and  instruments  related  to  any  of the
Subordinated Indebtedness by reason of any provision of this section 2 shall not
be construed as  preventing  the  occurrence  of any default or event of default
with respect to the Subordinated Indebtedness.

     2.10. Holders of Subordinated  Indebtedness Entitled to Assume Payments Not
           ---------------------------------------------------------------------
Prohibited in Absence of Notice. No holder of Subordinated Indebtedness shall at
- -------------------------------
any time be charged  with  knowledge  of the  existence of any facts which would
prohibit  the making of any payment to it,  unless and until such  holder  shall
have received  written  notice  thereof from the Companies or from any holder of
Superior  Indebtedness  or any  agent or  representative  thereof.  Prior to the
receipt of any such notice,  each holder of Subordinated  Indebtedness  shall be
entitled to assume  conclusively  that no such facts  exist,  without,  however,
limiting any right of any holder of Superior  Indebtedness  under this section 2
to recover from any holder of the Subordinated  Indebtedness any payment made in
contravention of this section 2. Each payment on the  Subordinated  Indebtedness
by the Companies shall be deemed to constitute a representation of the Companies
that such payment is permitted to be paid by the Companies under this section 2.

     Each holder of Subordinated  Indebtedness  shall be entitled to rely on the
delivery  to it of a written  notice by a Person  representing  himself  to be a
holder of  Superior  Indebtedness  or to be the agent or  representative  of any
holder of Superior  Indebtedness to establish that such notice has been given by
any such Person.

     2.11. Limitation  on  Right of  Action.  Notwithstanding  anything  to  the
           --------------------------------
contrary  contained  in any of the  Subordinated  Notes or any other  agreement,
document or instrument related thereto,  each of the holders of the Subordinated
Indebtedness agrees that:

          (a)  if any Superior  Indebtedness (or any commitment to fund Superior
     Indebtedness) is outstanding,  such holder of the Subordinated Indebtedness
     will not accelerate any of the Subordinated  Indebtedness or take any other
     enforcement action with respect to the Subordinated Indebtedness on account
     of any Default or Event of Default, unless:

               (i) the holder or holders of any Superior Indebtedness shall have
          accelerated  any Superior  Indebtedness  or shall have foreclosed upon
          any significant or material portion of collateral securing the same;

               (ii) a proceeding  under the Bankruptcy Code or any similar state
          statute or law (including  any law providing for the  appointment of a
          receiver or other similar  official)  shall have been  commenced by or
          against

                                  Exhibit 1(a)

                                      -14-


          any  Company by Persons  other  than the  holders of the  Subordinated
          Indebtedness; or

               (iii) both (A) an Event of Default  under (and as defined in) the
                           -
          Securities  Purchase  Agreements  shall have occurred and (B) not less
                                                                     -
          than  20  days  prior  to   accelerating   any  of  the   Subordinated
          Indebtedness  or taking any other  enforcement  action with respect to
          the   Subordinated   Indebtedness,   such   holder   of   Subordinated
          Indebtedness  shall have given the  Companies  and the  holders of the
          Superior  Indebtedness  written  notice  of the same (an  "Enforcement
          Notice"),  which Enforcement Notice shall specify in reasonable detail
          the  Event  of  Default  on the  basis  of which  such  holder  of the
          Subordinated  Indebtedness then intends to accelerate the Subordinated
          Indebtedness and/or take any other enforcement  action,  provided that
                                                                   --------
          for  purposes  of this  clause  (iii) if,  at the time of giving  such
          Enforcement  Notice (or during the 20 days  immediately  following the
          giving of such  Enforcement  Notice) a Blockage Period shall have been
          commenced and shall be  continuing,  then such holder of  Subordinated
          Indebtedness shall not accelerate any of the Subordinated Indebtedness
          or  take   enforcement   action  with  respect  to  the   Subordinated
          Indebtedness  until  the  earliest  of (1) in the  case  of a  Payment
                                                  -
          Default Blockage Period,  the cure of the Payment Default on the basis
          of  which  such  Blockage  Period  was  commenced  (provided  no other
                                                              --------
          Blockage  Period is then in effect),  (2) the  written  waiver of such
                                                 -
          Payment Default or Covenant Default by the requisite holder or holders
          of the  Superior  Indebtedness  with  respect  to which  such  Payment
          Default or Covenant  Default  shall have  occurred  (provided no other
                                                               --------
          Blockage  Period  is  then in  effect),  (3)  the  expiration  of such
                                                    -
          Blockage  Period,  (4) the termination of such Blockage Period by such
                              -
          requisite  holder or holders of such Superior  Indebtedness or (5) the
                                                                          -
          expiration  of 180 days  from the date  upon  which  such  Enforcement
          Notice shall have been so given; and

          (b) if (i) such holder of Subordinated  Indebtedness  shall accelerate
                  -
     any of the Subordinated  Indebtedness or take any other enforcement  action
     with  respect  to the  Subordinated  Indebtedness,  in each case  solely on
     account of the Event of Default arising as a result of the  acceleration of
     any Superior Indebtedness, and (ii) the requisite holder or holders of such
                                     --
     Superior  Indebtedness  shall  rescind such  acceleration  of such Superior
     Indebtedness,  then such holder of Subordinated  Indebtedness shall rescind
     such  acceleration of such  Subordinated  Indebtedness  and shall cease any
     such  other   enforcement   action  with   respect  to  such   Subordinated
     Indebtedness.
