Ladies and Gentlemen:

     PSC INC., a New York corporation (the "Holding Company"),  and SPECTRASCAN,
INC., a Delaware corporation (formerly named  Spectra-Physics  Scanning Systems,
Inc.,  the surviving  corporation of the Merger  hereinafter  referred to) and a
Wholly-Owned  Subsidiary of the Holding Company (the  "Operating  Company") (the
Holding Company and the Operating Company are sometimes collectively referred to
herein as the "Companies" and each as a "Company"),  jointly and severally agree
with you as  follows.  Certain  capitalized  terms used  herein  are  defined in
section 15.

1.    Authorization of Securities; Other Purchasers; etc.

          (a) The  Operating  Company has  authorized  the issue and sale of its
     11.25% Senior  Subordinated Notes due June 30, 2006 (herein,  together with
     any notes issued in exchange  therefor or replacement  thereof,  called the
     "Notes") in the aggregate principal amount of $30,000,000. The Notes are to
     be substantially  in the form of Exhibit 1(a)(i) attached hereto.  Interest
     is payable on the Notes,  quarterly  in arrears on each March 31,  June 30,
     September  30 and  December  31,  commencing  September  30,  1996,  and at
     maturity.  In no event  shall the  amount  paid or agreed to be paid by the
     Operating  Company as  interest  and premium on any Note exceed the highest
     lawful rate permissible under any law applicable thereto.  The Notes are to
     be guaranteed by the Holding  Company and by each Subsidiary of the Holding
     Company  (other than any Foreign  Subsidiary  and the  Operating  Company),
     including  any Person which  hereafter  becomes a Subsidiary of the Holding




(1)  There  will  be  separate  but  identical  Securities  Purchase  Agreements
addressed to each of the Other Purchasers.


     Company  (other  than any  Foreign  Subsidiary),  pursuant  to a  guarantee
     substantially  in the form of Exhibit  1(a)(ii)  attached  hereto (each,  a
     "Note Guarantee"; collectively, the "Note Guarantees").

          (b) The  Holding  Company  has  authorized  the  issue and sale of its
     warrants  evidencing  rights to  purchase  975,000  shares of Common  Stock
     (subject to  adjustment)  (herein,  together  with any  warrants  issued in
     exchange  therefor or  replacement  thereof,  called the  "Warrants").  The
     Warrants are to be  exercisable on or after July 12, 1997, are to terminate
     at the close of business on July 12,  2006 and are to be  substantially  in
     the form of Exhibit 1(b) attached hereto.

          (c) The  Securities are to be issued under this Agreement and separate
     Securities Purchase Agreements (the "Other Securities Purchase Agreements")
     identical  herewith (except as to the name and address of each of the other
     purchasers)  being entered into  concurrently by the Companies with each of
     the other purchasers (the "Other  Purchasers") named in Schedule I attached
     hereto. The issue of Securities to you and the issues of Securities to each
     of the Other  Purchasers  are separate  transactions,  and you shall not be
     liable or responsible for the acts or defaults of the Other Purchasers.

2. Sale and Purchase of  Securities.  The  Companies  will issue and sell to you
and,  subject  to the terms  and  conditions  hereof  and in  reliance  upon the
representations  and  warranties  of the Companies  contained  herein and in the
other Operative Documents,  you will purchase from the Companies, at the Closing
specified  in section 3, such  Securities  as are  specified  on that portion of
Schedule I attached hereto as is applicable to you. The aggregate purchase price
of the Securities shall be $30,000,000, which shall be allocated (a) $29,400,000
to the  Notes  and  (b) $600,000  to the  Warrants.  The  Companies,  the  Other
Purchasers  and you agree  that the values  ascribed  to the  Securities  (which
values shall be used by the Companies,  the Other Purchasers and you, as well as
any subsequent holder of any of the Securities, for all purposes,  including the
preparation  of  tax  returns)  shall  be  determined  in  accordance  with  the
foregoing.

3.  Closing.  The closing of the sale and purchase of the  Securities  hereunder
(the  "Closing")  shall  take  place at the  office of  Messrs.  Choate,  Hall &
Stewart,  Exchange Place, 53 State Street, Boston,  Massachusetts 02109, on July
12,  1996 or such other date to which you may agree (the  "Closing  Date").  The
Closing  shall occur not later than 11:00 A.M.  Boston  time (your  reinvestment
deadline) on the Closing Date. At the Closing, the Companies will deliver to you
the  Securities  to be  purchased by you at the Closing  against  payment of the
purchase  price thereof to (or for the benefit of) the Companies in  immediately
available funds in accordance with the wire  instructions set forth on Exhibit 3
attached  hereto.  Delivery  of the  Securities  to be  purchased  by you at the
Closing  shall be made in the form of one or more  Notes and  Warrants,  in such
denominations  and  registered  in such  names as are  specified  on  Schedule I
attached hereto,  and in each case dated and, in the case of each Note,  bearing
interest from,  the Closing Date. If at the Closing the Companies  shall fail to



tender the Securities to be delivered to you thereat as provided  herein,  or if
at the Closing any of the conditions  specified in section 4 shall not have been
fulfilled to your  reasonable  satisfaction,  you shall,  at your  election,  be
relieved  of all  further  obligations  under this  Agreement,  without  thereby
waiving  any  other  rights  you may  have by  reason  of such  failure  or such
non-fulfillment.

4. Conditions to Closing. Your obligation to purchase and pay for the Securities
to be purchased by you hereunder at the Closing is subject to the fulfillment to
your satisfaction, prior to or at the Closing, of the following conditions:

     4.1.  Representations  and  Warranties  Correct.  The  representations  and
warranties  made by the Companies  herein and in the other  Operative  Documents
shall have been  correct when made and shall be correct at and as of the time of
the  Closing  (after  giving  effect  to  the  transactions  consummated  at the
Closing).

     4.2.  Performance;  No Default.  The  Companies  shall have  performed  all
agreements  and complied with all conditions  contained  herein and in the other
Operative  Documents  required to be performed or complied with by them prior to
or at the  Closing,  and at the  time of the  Closing,  no  Default  or Event of
Default shall exist and no condition shall exist which has resulted in, or could
reasonably be expected to result in, a Material Adverse Change.

      4.3.  Related Transactions.

          (a)  Pursuant  to and in  accordance  with the  terms of the Asset and

     (as  defined  in  the   Acquisition   Agreement),   and  (iii)  the  Seller

and warrant that (after giving  effect to the  transactions  consummated  at the
Closing):

corporation duly organized, validly existing and in good standing under the laws
of its jurisdiction of  incorporation  and has all requisite power and authority
to own,  lease and  operate  its  properties,  to carry on its  business  as now

Operative  Documents to which it is (or is to be) a party and to consummate  the
transactions  contemplated  by  the  Operative  Documents.  No  approval  of the
stockholders  of either  Company or any class  thereof is required in connection
therewith which has not previously been obtained.

     5.2.  Subsidiaries.  Exhibit 5.2 attached  hereto is a complete and correct
list of the Holding Company's Subsidiaries  (corporate or other) which correctly
specifies as to each such Subsidiary (a) its legal name, (b) the jurisdiction of
its  organization,  (c) each other  jurisdiction  in which it is qualified to do
business,  (d) the authorized Shares of each Subsidiary (specifying the class or
classes thereof) and the number of such Shares outstanding,  (e) the number (and

Each  Subsidiary of the Holding  Company is a  corporation  or other entity duly
organized,  validly  existing  and  in  good  standing  under  the  laws  of the
jurisdiction  of its  organization  and has all requisite power and authority to
own,  lease  and  operate  its  properties,  to  carry  on its  business  as now
conducted,  and now proposed to be  conducted,  as  described in the  Disclosure
Document referred to in section 5.4 and to execute,  deliver and perform each of
the  Operative  Documents to which it is (or is to be) a party and to consummate
the transactions  contemplated  thereby.  All of the outstanding  Shares of each
Subsidiary  of  the  Holding  Company  are  validly   issued,   fully  paid  and
nonassessable  and not  subject  to  preemptive  rights on the part of any other
Person, and all of such Shares have been offered,  issued and sold by the issuer
thereof in compliance with all applicable laws. All of the Shares of the Holding
Company's  Subsidiaries  owned by the Holding  Company and its  Subsidiaries  as
shown on Exhibit 5.2 attached hereto are so owned of record and beneficially and
free of any Lien (other than the Liens permitted  pursuant to section  14.9(a)),

Operating Company is a Wholly-Owned Subsidiary of the Holding Company.

     5.3.  Qualification.  The Holding  Company and each of its  Subsidiaries is
duly  qualified  or  licensed  to do  business  and is in good  standing in each
jurisdiction  in which the  character of the  properties  owned or leased or the
nature  of the  activities  conducted  makes  such  qualification  or  licensing
necessary,  except  for  those  jurisdictions  in  which  the  failure  to be so
qualified  or licensed or to be in good  standing has not resulted in, and could
not reasonably be expected to result in, a Material Adverse Change.

     5.4. Business, etc. The Holding Company and its Subsidiaries are engaged in
the  business  of  designing,  engineering,  manufacturing  and selling bar code
scanning  equipment  (the  "Business"),  as  further  described  in the  Holding
Company's  Annual  Report on Form 10-K  filed by the  Holding  Company  with the
Commission for the fiscal year ended  December 31, 1995,  including all exhibits
and appendices thereto (the "Disclosure Document"), a true, correct and complete
copy of which has been furnished to you.


      5.5.  Shares; Stockholders.

          (a) The authorized and  outstanding  Shares of the Holding Company are
     fully and accurately  described on Exhibit 5.5(a) attached  hereto.  All of
     the  outstanding  Shares of the Holding  Company are, and all Shares issued
     upon exercise of any Warrants in accordance with the terms thereof will be,
     validly issued,  fully paid and nonassessable and not subject to preemptive
     rights on the part of any other  Person,  and all of such  Shares have been
     (or will have  been)  offered,  issued and sold by the  Holding  Company in
     compliance  with all applicable  laws. The number of shares of Common Stock
     of the Holding  Company  beneficially  owned by each director and executive
     officer of the Holding Company and its  Subsidiaries  and each other Person
     that, individually or together with its Affiliates, beneficially owns 5% or
     more of such shares of Common Stock (on a fully diluted basis),  along with
     the  percentage  of the total  outstanding  shares  of Common  Stock of the
     Holding Company that such number  represents of Common Stock of the Holding
     Company  (on a fully  diluted  basis),  are set  forth  on  Exhibit  5.5(a)
     attached hereto.  There are no outstanding  Preferred Shares of the Holding
     Company.

          (b) Except as set forth on Exhibit 5.5(b) attached  hereto,  except as
     provided in sections 11 and 12 and except for the  Warrants:  (i) there are
     no  outstanding  rights,  options,  warrants or agreements for the purchase
     from,  or  sale  or  issuance  by,  the  Holding  Company  or  any  of  its
     Subsidiaries of any of its Shares or any other securities  convertible into
     or  exercisable  or  exchangeable  for  such  Shares;  (ii)  there  are  no
     agreements on the part of the Holding Company or any of its Subsidiaries to
     issue,  sell or distribute  any Shares or any  properties and assets of the
     Holding  Company  or any of its  Subsidiaries;  (iii) neither  the  Holding
     Company  nor any of its  Subsidiaries  has any  obligation  (contingent  or
     otherwise)  to purchase,  redeem or otherwise  acquire any of its Shares or
     any  interest  therein or to pay any dividend or make any  distribution  in
     respect  thereof;  and (iv) no Person is entitled to (A) any  preemptive or
     similar  right with  respect to the  issuance  of any Shares of the Holding
     Company or any of its  Subsidiaries  or (B) any rights with  respect to the
     registration   of  any  Shares  of  the  Holding  Company  or  any  of  its
     Subsidiaries under the Securities Act.

          (c) The  aggregate  number of shares of  Common  Stock  issuable  upon
     exercise in full of the Warrants  immediately  after the Closing is 975,000
     which,  if  then  issued,   would  constitute  6.8%  of  the  Common  Stock
     (calculated on a fully-diluted basis assuming the conversion,  exercise and
     exchange of all outstanding  securities convertible into and exercisable or
     exchangeable for shares of Common Stock,  including without  limitation the
     Warrants).  The Holding Company has reserved 975,000 shares of Common Stock
     solely for issuance upon exercise of the Warrants.


      5.6.  Financial Statements.  You have been furnished with:

          (a) the financial  statements  referred to on Exhibit 5.6(a)  attached
     hereto, which financial statements are complete and correct in all material
     respects (subject,  in the case of any unaudited financial  statements,  to
     the  absence  of  footnote   disclosure  and  normal   year-end  and  audit
     adjustments)  and have been prepared in  accordance  with GAAP applied on a
     consistent  basis throughout the periods covered thereby and present fairly
     in all  material  respects  the  financial  position  and  the  results  of
     operations and cash flows of the Person(s)  purported to be covered thereby
     as at the  respective  dates and for the  respective  periods  indicated in
     conformity  with  GAAP  (subject,  in the case of any  unaudited  financial
     statements,  to the absence of footnote  disclosure and normal year-end and
     audit adjustments);

          (b) the  projections  referred to on Exhibit 5.6(b)  attached  hereto,
     which  projections  were prepared in good faith, are based upon assumptions
     that the  Companies  believe  are  reasonable  and take  into  account  all
     material  information   regarding  the  matters  set  forth  therein.  Such
     projections  represent a reasonable estimate by the Companies of the future
     financial  performance  of the Holding  Company and its  Subsidiaries.  The
     Companies do not  presently  anticipate  any material  deviation  from such
     projections  and the  Companies  reasonably  believe  that the  results  of
     operations reflected therein are attainable; and

          (c) the pro forma unaudited  consolidated balance sheet of the Holding
     Company and its Subsidiaries referred to on Exhibit 5.6(c) attached hereto,
     which balance sheet fairly  presents the financial  position of the Holding
     Company and its  Subsidiaries  as at May 31, 1996,  adjusted on a pro forma
     basis to give effect to the consummation of the  transactions  contemplated
     by the Operative Documents,  and reflects all known material liabilities of
     the Holding  Company and its  Subsidiaries,  contingent or other, as at the
     Closing Date, required by GAAP to be reflected therein.

     5.7. Changes; Solvency, etc. Since December 31, 1995: (a) there has been no
change in the assets,  liabilities or financial condition of the Holding Company
and its  Subsidiaries  from that set forth in the balance  sheet as at such date
referred to on Exhibit 5.6 attached  hereto,  other than changes in the ordinary
course of business which have not been,  either in any case or in the aggregate,
materially  adverse;  (b) no condition or event has occurred  which has resulted
in, or could reasonably be expected to result in, a Material Adverse Change; and
(c) except  as set forth on Exhibit  5.7  attached  hereto,  neither the Holding
Company  nor any of its  Subsidiaries  has,  directly or  indirectly,  declared,
ordered,  paid or made any Restricted  Payment.  Each of the Holding Company and
its Subsidiaries are Solvent.


     5.8. Tax Returns and  Payments.  The Holding  Company and its  Subsidiaries
have filed all tax returns  required by law to be filed and have paid all taxes,
assessments  and  other  governmental   charges  levied  upon  their  respective
properties,  assets, income, receipts, franchises or sales, other than those not
yet delinquent and those, not substantial in aggregate amount, being or about to
be contested  as provided in section  14.2(a).  The income tax  liability of the
Holding Company and its Subsidiaries has been finally determined by the Internal
Revenue  Service,  and  satisfied,  or the time for audit has  expired,  for the
fiscal years listed on Exhibit 5.8 attached hereto.  The Holding Company and its
Subsidiaries  have not executed any waiver or waivers that would have the effect
of extending  the  applicable  statute of  limitations  in respect of income tax
liabilities.  The charges,  accruals and reserves in the financial statements of
the  Holding  Company  and its  Subsidiaries  in respect of taxes for all fiscal
periods are adequate in the opinion of the Companies,  and the Companies know of
no unpaid assessments for additional taxes for any fiscal period or of any basis
therefor.

     5.9. Funded Debt,  Current Debt,  Liens,  Investments and Transactions with
Affiliates. Exhibit 5.9 attached hereto correctly describes:

          (a) all Funded Debt and/or Current Debt of the Holding  Company and/or
     any of its Subsidiaries to be outstanding immediately following the Closing
     (other than that evidenced by the Notes);

          (b) all Liens to which any of the properties and assets of the Holding
     Company  and/or  any  of  its  Subsidiaries  will  be  subject  immediately
     following  the Closing  (other  than those of the  character  described  in
     section 14.9(b));

          (c) all  Investments  (and  all  agreements  and  commitments  to make
     Investments)  of the Holding  Company and/or any of its  Subsidiaries to be
     owned or held (or in effect) immediately  following the Closing (other than
     Cash Equivalents);

          (d)  all  Affiliates  of  the  Holding   Company  and/or  any  of  its
     Subsidiaries and all  transactions or series of transactions  that involved
     (or will involve) an aggregate  value of $1,000,000 or more with Affiliates
     of  the  Holding  Company  and/or  any  of  its  Subsidiaries   which  were
     consummated  during the 12-month  period ended on the Closing Date or which
     the Holding Company and/or any of its  Subsidiaries is now obligated or now
     intends to consummate at any time in the future; and

          (e) each lease,  other than  Capital  Leases,  under which the Holding
     Company  and/or any of its  Subsidiaries  is lessee or sublessee  and is or
     shall be  obligated  to pay  $25,000  or more  during  any period of twelve
     consecutive  months after the Closing Date,  and, with respect to each such
     lease,  the  name  of the  lessor,  the  lessee  or  sublessee,  a  general
     description of the property leased, the annual Rental  Obligations  payable
     thereunder and the term thereof.



     5.10.  Title to  Properties;  Liens;  Leases.  The Holding  Company and its
Subsidiaries  have  good  and  marketable  title  to  all  of  their  respective
properties and assets, including,  without limitation, the properties and assets
reflected in the balance sheet, dated December 31, 1995,  referred to on Exhibit
5.6 attached hereto, except properties and assets disposed of since such date in
the  ordinary  course  of  business,  free of all  Liens  (other  than the Liens
permitted under section 14.9).  The Holding Company and its  Subsidiaries  enjoy
peaceful and undisturbed  possession  under all material leases under which they
operate, and all of such leases are valid, subsisting and in full force and
effect. None of such leases contains any unusual or burdensome provision, which,
in either case, has resulted in, or could reasonably be expected to result in, a
Material Adverse Change.

     5.11. Litigation,  etc. Except as set forth on Exhibit 5.11(a), there is no
action,  proceeding  or  investigation  pending or, to the  knowledge  of either
Company,  threatened  (or any  basis  therefor  known to either  Company)  which
questions the validity of any of the Operative  Documents or any action taken or
to be taken  pursuant  thereto or which has resulted in, or could  reasonably be
expected  to result  in, a  Material  Adverse  Change.  There is no  outstanding
judgment, decree or order which has resulted in, or could reasonably be expected
to result in, a Material  Adverse Change.  Exhibit 5.11(b)  attached hereto is a
complete and correct  list of all actions and  proceedings  pending  against the
Holding Company and any of its Subsidiaries.

     5.12.  Valid and Binding  Obligations;  Compliance with Other  Instruments,
Borrowing Restrictions, etc.

          (a) This Agreement has been duly authorized, executed and delivered by
     each Company and constitutes  the valid and legally  binding  obligation of
     each Company enforceable against such Company in accordance with its terms.
     Each of the other Operative Documents to which either Company and/or any of
     their  respective  Subsidiaries is a party has been duly authorized by such
     Person and,  when executed and  delivered,  will  constitute  the valid and
     legally  binding  obligation  of such  Person,  enforceable  against  it in
     accordance with its terms.

          (b) Neither of the Companies nor any of their respective  Subsidiaries
     is in  violation  of or in  default  under  any term of its  Organizational
     Documents, or of any agreement,  document,  instrument,  judgment,  decree,
     order,  law,  statute,  rule or  regulation  applicable to it or any of its
     properties  and  assets,  in any  way  which  has  resulted  in,  or  could
     reasonably  be expected to result in, a Material  Adverse  Change.  Without
     limiting the generality of the foregoing,  the Holding  Company and each of
     its  Subsidiaries  is in  compliance  with (and  neither  it nor any of its
     predecessors in interest has received any notice to the contrary) and there
     is no reasonable possibility of any liability of or any judgment, decree or
     order binding upon or applicable to the Holding  Company  and/or any of its
     Subsidiaries or any of their  respective  properties and assets under or on
     account of any Environmental Laws, except where the same has not


      resulted in, and could not reasonably be expected to result in, a Material
      Adverse Change.

          (c) The execution, delivery and performance of and the consummation of
     the transactions  contemplated by the Operative  Documents will not violate
     or  constitute a default  under,  or permit any Person to  accelerate or to
     require the prepayment of any Indebtedness of the Holding Company or any of
     its  Subsidiaries  or to terminate  any material  lease or agreement of the
     Holding  Company or any of its  Subsidiaries  pursuant to, or result in the
     creation  of any Lien upon any of the  properties  or assets of the Holding
     Company  or  any  of  its  Subsidiaries   pursuant  to,  any  term  of  its
     Organizational  Documents  or  of  any  agreement,   document,  instrument,
     judgment, decree, order, law, statute, rule or regulation applicable to any
     of them or any of their respective properties and assets.

          (d) Neither the Holding Company nor any of its Subsidiaries is a party
     to or bound by or subject to any agreement, document, instrument, judgment,
     decree,  order, law, statute,  rule or regulation (other than the Operative
     Documents  and the Bank  Credit  Agreement  and  laws,  statutes,  rules or
     regulations   affecting  creditors  or  businesses   generally)  (i)  which
     restricts its right or ability to incur  Indebtedness,  to issue securities
     or to consummate the transactions contemplated hereby; (ii) under the terms
     of or  pursuant  to which its  obligation  to pay all  amounts  due from it
     and/or to perform all  obligations  imposed on it and/or to comply with the
     terms  applicable to it under any of the Operative  Documents is in any way
     restricted;  (iii)  which  restricts  its  right  or  ability  to make  any
     distributions  to its  stockholders or in respect of any of its Shares,  to
     mortgage  or  dispose  of  its   properties,   to  consummate  any  merger,
     consolidation or acquisition,  to make Investments or Capital Expenditures,
     to enter into and perform leases, to pay executive  compensation  and/or to
     conduct its business as now conducted and now proposed to be conducted,  or
     (iv) which has resulted in, or could reasonably be expected to result in, a
     Material Adverse Change.

      5.13. ERISA.

          (a)  Each  Company  and  each  ERISA   Affiliate   have  operated  and
     administered  each Plan in compliance  with all applicable  laws except for
     such instances of  noncompliance  which have not resulted in, and could not
     reasonably  be expected to result in, a Material  Adverse  Change.  Neither
     Company nor any ERISA  Affiliate  has  incurred any  liability  pursuant to
     Title I or IV of ERISA or the penalty or excise tax  provisions of the Code
     relating to employee benefit plans (as defined in section 3 of ERISA),  and
     no event,  transaction  or  condition  has  occurred  or exists  that could
     reasonably be expected to result in the incurrence of any such liability by
     either Company or any ERISA Affiliate,  or in the imposition of any Lien on



     any of the  rights,  properties  or assets of either  Company  or any ERISA
     Affiliate,  in either  case  pursuant  to Title I or IV of ERISA or to such
     penalty or excise tax  provisions  or to section  401(a)(29)  or 412 of the
     Code,  other than such liabilities or Liens as would not individually or in
     the aggregate result in a Material Adverse Change.

          (b) The present value of the aggregate benefit  liabilities under each
     of the Plans (other than Multiemployer Plans),  determined as of the end of
     such Plan's  most  recently  ended plan year on the basis of the  actuarial
     assumptions  specified  for  funding  purposes  in such  Plan's most recent
     actuarial  valuation report,  did not exceed the aggregate current value of
     the assets of such Plan  allocable  to such benefit  liabilities.  The term
     "benefit  liabilities"  has the meaning  specified in section 4001 of ERISA
     and the  terms  "current  value"  and  "present  value"  have  the  meaning
     specified in section 3 of ERISA.

          (c)  The  Companies  and  the  ERISA   Affiliates  have  not  incurred
     withdrawal  liabilities  (and  are not  subject  to  contingent  withdrawal
     liabilities)   under   section   4201  or  4204  of  ERISA  in  respect  of
     Multiemployer Plans that individually or in the aggregate could result in a
     Material  Adverse Change.  The Companies and the ERISA Affiliates have made
     all required  contributions to Multiemployer Plans. Neither Company nor any
     ERISA Affiliate has incurred,  nor would  reasonably  expect to incur,  any
     Withdrawal  Liability  upon a  complete  or  partial  withdrawal  from  any
     Multiemployer  Plan that individually or in the aggregate could result in a
     Material  Adverse  Change.  To the  best of the  Companies'  knowledge,  no
     Multiemployer  Plan is, or is  reasonably  expected  to be,  insolvent,  in
     reorganization or terminated within the meaning of Title IV of ERISA.

          (d) Neither the Holding  Company nor any of its  Subsidiaries  has any
     material post retirement benefit obligations (determined in accordance with
     Financial  Accounting  Standards Board Statement No. 106, without regard to
     liabilities attributable to continuation coverage mandated by section 4980B
     of the Code).

          (e) The consummation of the transactions contemplated by the Operative
     Documents  will  not  involve  any  transaction  that  is  subject  to  the
     prohibitions  of section 406(a) of ERISA or in connection  with which a tax
     could be imposed  pursuant to section  4975(c)(1)(A)-(D)  of the Code.  The
     representation  by the  Companies  in the first  sentence  of this  section
     5.13(e)  is made in  reliance  upon and  subject  to the  accuracy  of your
     representation in section 26 as to the sources of the funds used to pay the
     purchase price of the Securities to be purchased by you.

     5.14.  Consents,  etc.  No  consent,   approval  or  authorization  of,  or
declaration or filing with, or other action by, any Person  (including,  without
limitation,  any  creditor  of or lender to the  Holding  Company  or any of its
Subsidiaries and any governmental (13)


authority) is required as a condition precedent to the valid execution, delivery
and performance of and the consummation of the transactions  contemplated by the
Operative Documents. 

     5.15.  Proprietary  Rights;  Licenses.  Except as disclosed on Exhibit 5.15
attached hereto,  the Holding Company and its Subsidiaries  have all Proprietary
Rights  and  Licenses  as are  adequate  for the  conduct  of  their  respective
businesses as now conducted and now proposed to be conducted,  without any known
conflict with the rights of others.  Each such Proprietary  Right and License is
in full force and effect,  all material  obligations  with respect  thereto have
been fulfilled and performed and, to the knowledge of the Companies, there is no
infringement  thereon by any other  Person.  No default  in the  performance  or
observance by the Holding  Company  and/or any of its  Subsidiaries  (or, to the
knowledge of the Companies, any of their respective predecessors in interest) of
its obligations  thereunder has occurred which permits, or after notice of lapse
of time or both would  permit,  the  revocation or  termination  of any material
Proprietary  Right or License or which has resulted in, or could  reasonably  be
expected to result in, a Material Adverse Change.

     5.16. Offer of Securities;  Investment Bankers.  Neither Company nor any of
their  respective  Subsidiaries  nor any Person  acting on their behalf  (a) has
directly or indirectly offered the Securities or any part thereof or any similar
securities  for issue or sale to, or solicited  any offer to buy any of the same
from,  anyone other than you and the Other Purchasers and not more than 65 other
institutional investors, (b) has taken or will take any action which would bring
the issuance and sale of the  Securities  within the  provisions of Section 5 of
the  Securities  Act or the  registration  or  qualification  provisions  of any
applicable  blue sky or other  securities  laws,  (c) has dealt with any broker,
finder,  commission agent or other similar Person in connection with the sale of
the  Securities  and  the  other  transactions  contemplated  by  the  Operative
Documents, other than Fleet National Bank, or (d) is under any obligation to pay
any  broker's  fee,   finder's  fee  or  commission  in  connection   with  such
transactions,  other  than  a fee  to  Fleet  National  Bank,  which  fee is the
obligation solely of the Holding Company.

     5.17.  Government  Regulation.  Neither the Holding  Company nor any of its
Subsidiaries  is subject to regulation  under the Public Utility Holding Company
Act of 1935,  the Federal Power Act, the  Investment  Company Act of 1940 or the
Interstate Commerce Act, each as amended.

     5.18. Labor Relations;  Suppliers,  Distributors and Customers.  No dispute
involving  employees of the Holding  Company or any of its  Subsidiaries  or the
relationship  of  the  Holding  Company  or any of  its  Subsidiaries  with  its
employees  has  resulted in, or could  reasonably  be expected to result in, any
Material  Adverse  Change.   The   relationships   with  the  suppliers  to  and
distributors  for and customers of the Holding Company and its  Subsidiaries are
satisfactory  commercial  working  relationships and, during the 12-month period
ended on the  Closing  Date,  no such  supplier,  distributor  or  customer  has



cancelled  or  otherwise  terminated  its  relationship  with or  decreased  its
services,  supplies or  materials to or its usage or purchase of the services or
products of the Holding Company or any of its Subsidiaries in a manner which has
resulted in, or could  reasonably  be expected to result in, a Material  Adverse
Change.  The Holding Company is not aware of any intention of any such supplier,
distributor  or  customer  to take any such action  which  could  reasonably  be
expected to result in a Material Adverse Change.

     5.19.  Voting  Provisions.  Except as set forth on  Exhibit  5.19  attached
hereto,  neither the  Organizational  Documents  of the Holding  Company nor any
other agreement,  document or instrument binding on or applicable to the Holding
Company or its  stockholders  contains any  provision  requiring a higher voting
requirement   with  respect  to  action  taken  (and/or  to  be  taken)  by  the
stockholders  or directors of the Holding Company than that which would apply in
the absence of such provision.

     5.20.  Disclosure.  Neither this  Agreement nor any of the other  Operative
Documents nor any other document,  certificate or written statement furnished to
you by or on behalf of either Company or any of their respective Subsidiaries in
connection  with  the  transactions  contemplated  by  the  Operative  Documents
(including,  without limitation,  the Disclosure Document),  contains any untrue
statement  of a material  fact or omits to state a material  fact  necessary  in
order to make the statements  contained herein and therein not misleading in the
light of the  circumstances  under  which such  statements  were made,  it being
understood  that,  except as set forth in  section  5.6,  no  representation  or
warranty is made with respect to any projections or other prospective  financial
information.  There is no fact known to either Company  (other than  information
concerning general economic  conditions known to the public generally) which has
resulted in, or could  reasonably  be expected to result in, a Material  Adverse
Change  which has not been set  forth in this  Agreement,  the  other  Operative
Documents and the other documents,  certificates and written statements referred
to above in this section 5.20.

6.    Use of Proceeds.

          (a)  The  proceeds  of the  sale  of the  Securities  received  by the
     Companies  at the  Closing  will be used on the  Closing  Date to make  the
     payments  to the  Persons  and for the  purposes  specified  on  Exhibit  6
     attached hereto and any remaining balance of such proceeds will be used for
     general corporate purposes of the Operating Company and its Subsidiaries.

          (b) The Companies do not own, and will not, and will not permit any of
     their respective  Subsidiaries to, directly or indirectly,  use any part of
     the proceeds of the sale of the Securities for the purpose of purchasing or
     carrying any "margin stock" within the meaning of Regulation G (12 CFR Part
     207) of the Board of Governors of the Federal Reserve System (herein called
     a "margin  security")  or for the  purpose  of  reducing  or  retiring  any
     Indebtedness which was originally  incurred to purchase or carry any margin



     security or for any other purpose which might  constitute the  transactions
     contemplated  by the  Operative  Documents  a "purpose  credit"  within the
     meaning of said  Regulation  G or cause this  Agreement or any of the other
     Operative  Documents to violate Regulation G or any other regulation of the
     Board of Governors of the Federal  Reserve  System,  or the Exchange Act or
     any other applicable law, statute, regulation, rule, order or restriction.

     Indebtedness),  including,  without  limitation,  any  notice of default or
     event of default  under the Seller Notes and/or the Bank Credit  Agreement,

          (j) such  other  information  as from time to time may  reasonably  be
     requested.

8.  Inspection.  The Holding  Company will permit any Person  designated  by any
institutional holder of any of the Notes or Warrants on reasonable notice and at
such holder's  expense (unless a Default or Event of Default shall have occurred
and be  continuing,  in which case,  at the  Companies'  expense),  to visit and
inspect any of the properties of the Holding  Company and its  Subsidiaries,  to
examine  its and their books and  records  (and to make copies  thereof and take
extracts therefrom) and to discuss its and their affairs,  finances and accounts
with and to be  advised as to the same by, its and their  officers  and  outside
counsel  (and if a  Default  or Event of  Default  shall  have  occurred  and be
continuing,  its and their independent  accountants,  each of whom the Companies
hereby  direct  and  authorize  to  engage  in  such   discussions   under  such
circumstances),  all at such  reasonable  times and intervals as such holder may
desire. 

9. Prepayment of Notes.

     9.1.  Required Annual  Prepayment  Without Premium of Notes. In addition to
paying the entire  outstanding  principal  amount of and the interest due on the
Notes on the maturity date thereof,  on each June 30,  commencing June 30, 2003,
until  the Notes  have been paid in full,  the  Operating  Company  will  prepay
without  premium  $7,500,000  principal  amount  of the  Notes  (or such  lesser
principal amount thereof as shall then be outstanding). No partial prepayment of
the Notes  shall  alter the  obligation  of the  Operating  Company  to make the
required prepayments provided for in this section 9.1.

     9.2.  Optional  Prepayment With Premium of Notes. At any time and from time
to time, the Operating  Company may, at its option,  upon notice as set forth in
section 9.5,  prepay all or any part (in an integral  multiple of $500,000 and a
minimum of $1,000,000 or such lesser  principal  amount thereof as shall then be
outstanding) of the Notes upon the concurrent  payment of an amount equal to the
Make Whole Amount.  Any partial prepayment of Notes pursuant to this section 9.2
shall be applied to the payment of  installments  of  principal  of the Notes in
inverse order of maturity.

     9.3.  Optional  Prepayment  With  Premium of the Notes with the Proceeds of
Certain Public Offerings.  Concurrent with (or immediately  following) a closing
of a sale by the  Holding  Company to the public of its  Shares  pursuant  to an
effective   registration  statement  filed  by  the  Holding  Company  with  the
Commission  under the  Securities  Act  resulting in net proceeds to the Holding
Company from such sale of not less than $25,000,000,  the Operating Company may,
at its option,  upon notice as set forth in section 9.5,  prepay all (subject to
the limitation set forth in the second proviso to this sentence) or any part (in
an  integral  multiple of $500,000  and a minimum of  $1,000,000  or such lesser
principal  amount  thereof as shall then be  outstanding)  of the Notes upon the
concurrent  payment  of an  amount  equal  to the  Special  Prepayment  Premium,



provided that such prepayment  shall be made only with available net proceeds of
such sale of Shares to the public, and provided, further, that in no event shall
the aggregate  principal  amount of Notes prepaid by the Operating  Company from
time to time  pursuant  to this  section  9.3 exceed  $10,000,000.  Each  notice
pursuant  to  section  9.5 of a  prepayment  under  this  section 9.3  shall  be
accompanied by an Officers'  Certificate  certifying and demonstrating that this
section 9.3  is being  complied  with in  connection  with such  prepayment  and
specifying  the source or sources of funds to be used for such  prepayment.  Any
partial prepayment of Notes pursuant to this section 9.3 shall be applied to the
payment of installments of principal of the Notes in inverse order of maturity.

     9.4.  Allocation  of  Partial  Prepayments  of  Notes.  In the case of each
partial prepayment of the Notes under this section 9, the principal amount to be
prepaid  shall be  allocated  among  all of the  Notes  at the time  outstanding
(excluding  any Notes at the time owned by either  Company or any  Affiliate  of
either  Company) in  proportion,  as nearly as  practicable,  to the  respective
unpaid principal amounts thereof,  with adjustments,  to the extent practicable,
to compensate for any prior prepayments not made exactly in such proportion.

     9.5.  Notice  of  Optional  Prepayments  of  Notes.  In the  case  of  each
prepayment under sections 9.2 and 9.3, the Operating  Company shall give written
notice  thereof  to each  holder  of any Notes not less than 30 nor more than 60
days prior to the date fixed for such  prepayment.  Each such  notice  shall set
forth:  (a) the date fixed for  prepayment  (which,  in the case of a prepayment
under  section  9.3 may be a good faith  approximation  of such  date);  (b) the
aggregate  principal  amount of Notes to be prepaid on such  date;  and  (c) the
aggregate  principal  amount of Notes held by such  holder to be prepaid on such
date and the amount of accrued  interest  and an  estimation  of the  Applicable
Premium to be paid to such holder on such date (together with the calculation of
such estimated  Applicable  Premium,  which calculation shall be satisfactory to
each holder of the Notes to be prepaid).

     9.6. Maturity;  Accrued Interest;  Surrender, etc. of Notes. In the case of
each  prepayment  of all or any part of any  Note,  the  principal  amount to be
prepaid  shall  mature  and  become  due and  payable on the date fixed for such
prepayment, together with interest on such principal amount accrued to such date
and the  premium,  if any,  due  thereon.  Any  Note  prepaid  in full  shall be
surrendered to the Operating Company at the Operating  Company's principal place
of  business  promptly  following  prepayment  and  cancelled  and  shall not be
reissued, and no Note shall be issued in lieu of any prepaid principal amount of
any Note.

     9.7.  Purchase of Notes.  The  Companies  will not, and will not permit any
Affiliate of either Company to,  directly or  indirectly,  purchase or otherwise
acquire, or offer to purchase or otherwise acquire, any outstanding Notes except
by way of payment or prepayment in accordance  with the  provisions of the Notes
and this Agreement.



     9.8.  Payment on  Non-Business  Days. If any amount  hereunder or under the
Notes shall become due on a day which is not a Business  Day, such payment shall
be due on the next succeeding Business Day.

     9.9. Application of Notes in Satisfaction of Exercise Price of Warrants. In
the event  that any  holder of any Note  shall  apply all or any  portion of the
principal  amount  of such  Note in  satisfaction  (in  whole or in part) of the
payment  of the  Exercise  Price  (as  defined  in the  Warrants),  any  partial
application  of the  principal  amount of any such Note  shall be applied to the
payment of  installments  of principal  due  thereunder  in the inverse order of
maturity.

     definition of such term, other forms reasonably  satisfactory to the holder
     or holders of at least 75% in  aggregate  principal  amount of the Superior
     Indebtedness,  or a combination of the  foregoing),  the Obligors shall not
     grant to the holders of the Subordinated Indebtedness any Lien in or on any

creditors,  or any other  marshalling  of the  assets  and  liabilities  of such
Company,  or otherwise  (hereinafter a "Liquidation  Payment"),  then and in any
such event: 

          (a) the  holders of the  Superior  Indebtedness  shall be  entitled to
     receive payment in full (in cash, Cash Equivalents of the kind described in
     clause  (a)  of  the  definition  of  such  term,  other  forms  reasonably
     satisfactory  to the  holder  or  holders  of at  least  75%  in  aggregate
     principal  amount of the Superior  Indebtedness,  or a  combination  of the

     reasonably  satisfactory  to the holders of Superior  Indebtedness)  of all
     Superior  Indebtedness,  before any Liquidation  Payment,  whether in cash,
     property or  securities  (other than  Permissible  Securities),  is made on
     account of or applied to the Subordinated Indebtedness; 


          (b) the  Subordinated  Indebtedness  shall  forthwith  become  due and
     payable,  and  any  Liquidation  Payment,  whether  in  cash,  property  or

     liquidating trustee, agent or other Person making such Liquidation Payment,

     Superior Indebtedness in full after giving effect to any concurrent payment
     or  distribution,  or provision  therefor,  to the holders of such Superior
     Indebtedness; and

          (c)  each  holder  of  the  Subordinated   Indebtedness  at  the  time
     outstanding hereby  irrevocably  authorizes and empowers each holder of the
     Superior  Indebtedness  or such  holder's  representative  to  collect  and
     receive  such  holder's  ratable  share of any  Liquidation  Payment and to
     receipt therefor, and, if any holder of Subordinated  Indebtedness fails to
     file a claim  therefor at least seven (7)  calendar  days prior to the date
     established  by rule of law or order of court for such filing,  to file and
     prove (but not to vote) such claims therefor,  provided that such holder of
     Superior  Indebtedness  shall  concurrently  send written notice thereof to
     each holder of Subordinated Indebtedness, together with a copy of the proof
     of claim so filed.

     Upon any payment or  distribution of assets referred to in this section 10,

order or  decree  made by any  court of  competent  jurisdiction  in which  such
bankruptcy,  insolvency,  reorganization,  liquidation,  receivership  or  other
proceeding is pending,  or a certificate of the debtor,  custodian,  liquidating
trustee,  agent or other Person making any such payment or  distribution to such
holders,  for the purpose of  ascertaining  the Persons  entitled to participate
therein,  the  holders  of  the  Superior  Indebtedness,  the  then  outstanding
principal  amount of the Superior  Indebtedness  and any and all amounts payable
thereon,  the amount or amounts paid or distributed  thereon and all other facts
pertinent thereto or to this section 10.

     10.4.  No Payments  With Respect to  Subordinated  Indebtedness  in Certain
Circumstances.  

          (a) The Obligors will not,  directly or  indirectly,  make or agree to
     make,  and neither the holder nor any assignee or  successor  holder of any
     Subordinated   Indebtedness   will   accept  or  receive   any  payment  or
     distribution  (in cash,  property or  securities  (other  than  Permissible
     Securities) by set-off or otherwise),  direct or indirect, of or on account
     of all or any portion of any  Subordinated  Indebtedness if, at the time of
     such payment or distribution or immediately after giving effect thereto all
     of the following four conditions shall be satisfied:


               (i) a Material  Default shall have occurred  which (other than in
          the  case of a  default  under  section  6.01(f)  of the  Bank  Credit
          Agreement) permits the holder or holders of any Superior  Indebtedness
          to immediately accelerate the maturity thereof;

               (ii)  the  Operating   Company  and  the  holder  or  holders  of
          Subordinated Indebtedness shall have received written notice (given as
          provided in this Agreement)  (each a  "Subordination  Notice") of such
          Material   Default  from  the  holder  or  holders  of  such  Superior
          Indebtedness, or their representative or representatives (which notice
          shall  state  that  it is a  "Subordination  Notice"  and  shall  make
          explicit reference to the provisions of this section 10.4);

               (iii)  such  Material  Default  shall not have been  cured by any
          Obligor or waived in writing by the requisite holder or holders of the
          Superior  Indebtedness  with  respect to which such  Material  Default
          shall have occurred; and

               (iv)  less than 150 days  shall  have  elapsed  after the date of
          receipt by the Operating  Company and the holders of the  Subordinated
          Indebtedness of such Subordination Notice (any period during which the
          restrictions  imposed  by this  Section  10.4(a)  are in effect  being
          hereinafter referred to as a "Blockage Period");

     provided,  however, that, for the purpose of this section 10.4(a),  (x) not
     more than one Blockage  Period shall be in effect  during any period of 360
     consecutive  days, (y) Blockage Periods shall not be in effect on more than
     three occasions, and (z) no facts or circumstances  constituting a Material
     Default on the date any Subordination  Notice is given may be used or shall
     be effective as a basis for any subsequent Subordination Notice.

          (b) The  restrictions  imposed by section 10.4(a) shall cease to apply
     and the  Obligors  may  resume  payments  in  respect  of the  Subordinated
     Indebtedness  (including  any  payments  which  shall not have been made on
     account of the  provisions  of this section 10, but  excluding any payments
     which may have  become due solely on  account  of any  acceleration  of the
     maturity of the  Subordinated  Indebtedness)  or any judgment  with respect
     thereto upon the earliest to occur of (i) the cure of the Material  Default
     by any Obligor,  (ii) the written waiver thereof by the requisite holder or
     holders of the Superior  Indebtedness  with respect to which such  Material
     Default shall have occurred,  (iii) the  expiration of the Blockage  Period
     and (iv) the termination of such



     Blockage  Period by such  requisite  holder  or  holders  of such  Superior
     Indebtedness.

          (c) In the event any of (i) a  default in the payment of any principal
     or  interest  that  constitutes  a  default  in  the  payment  of  Superior
     Indebtedness,  which default  continues  unremedied and unwaived,  (ii) the
     failure of the Obligors to pay any Superior  Indebtedness upon the maturity
     thereof or (iii) an  acceleration  of the maturity of the  principal of any
     Superior   Indebtedness   in  accordance  with  the  terms  thereof  (which
     acceleration   has  not  been   rescinded  or   annulled),   such  Superior
     Indebtedness  shall first be paid in full (in cash, Cash Equivalents of the
     kind  described in clause (a) of the  definition of such term,  other forms
     reasonably  satisfactory  to the  holder  or  holders  of at  least  75% in
     aggregate principal amount of the Superior  Indebtedness,  or a combination
     of the  foregoing) (or provision for such payment shall be made in a manner
     reasonably   satisfactory  to  the  holder  or  holders  of  such  Superior
     Indebtedness)  before any payment or distribution  (in cash,  properties or
     securities (other than Permissible Securities), by set-off or otherwise) is
     made on account of or applied on the Subordinated Indebtedness.

          (d) Nothing  herein  shall affect or impair the right of any holder of
     any Notes to apply any amount payable in respect  thereof to the payment of
     any amount due upon the exercise of any Warrants at any time.

     10.5. Payments and Distributions  Received.  If any payment or distribution
of any kind or character,  whether in cash,  property or securities  (other than
Permissible  Securities),  shall  be  received  by  any  holder  of  any  of the
Subordinated  Indebtedness in  contravention of this section 10, such payment or
distribution  shall be held in trust for the  benefit of, and shall be paid over
or delivered and  transferred to, the holders of the Superior  Indebtedness,  or
their  representative  or  representatives,  ratably  according to the aggregate
amount  remaining  unpaid  on  account  of  such  Superior   Indebtedness,   for
application  to the payment  thereof,  to the extent  necessary  to pay all such
Superior  Indebtedness in full, after giving effect to any concurrent payment or
distribution,   or  provision   therefor,   to  the  holders  of  such  Superior
Indebtedness,  provided, that amounts so paid over shall be returned promptly to
the  applicable  holders  of the  Subordinated  Indebtedness  in the  event  the
Superior Indebtedness was otherwise paid in full. In the event of the failure of
any holder of any of the Subordinated Indebtedness to endorse or assign any such
payment  or  distribution,  any  holder  of the  Superior  Indebtedness  or such
holder's  representative is hereby  irrevocably  authorized to endorse or assign
the same. 

     10.6.  Subrogation.  Subject  to  the  payment  in  full  of  all  Superior
Indebtedness,  in  case  cash,  property  or  securities  otherwise  payable  or
deliverable  to the  holders of the  Subordinated  Indebtedness  shall have been
applied  pursuant to this  section 10 to the  payment of Superior  Indebtedness,
then and in each such case, the holders of the Subordinated  Indebtedness  shall
be subrogated to the rights of each holder of Superior


Indebtedness  to receive any further  payment or  distribution  in respect of or
applicable  to  the  Superior  Indebtedness;  and,  for  the  purposes  of  such
subrogation,  no payment or distribution to the holders of Superior Indebtedness
of any  cash,  property  or  securities  to which  any  holder  of  Subordinated
Indebtedness  would be entitled  except for the  provisions  of this  section 10
shall,  and no payment over pursuant to the provisions of this section 10 to the
holders of Superior Indebtedness by the holders of the Subordinated Indebtedness
shall as between  the  Obligors,  their  creditors  (other  than the  holders of
Superior Indebtedness) and the holders of Subordinated  Indebtedness,  be deemed
to be a payment by the Obligors to or on account of Superior Indebtedness.

     10.7.  Notice.  In the event that any  Subordinated  Indebtedness  shall be
transferred  and/or shall become due and payable  before the expressed  maturity
thereof as the result of the occurrence of a default, the Operating Company will
give  immediate  written  notice in writing of such  happening to each holder of
Superior  Indebtedness  (together,  in the case of any such  transfer,  with the
address of the  transferee for purposes of this section 10, it being agreed that
the holders of Superior  Indebtedness shall not be obligated to give to any such
transferee any notice  required  hereunder to be given by them to the holders of
Subordinated Indebtedness unless the holders of Superior Indebtedness shall have
received  such notice (and the address of such  transferee)  from the  Operating
Company  (or, in the case of any such  transfer,  a notice  from the  transferee
containing substantially the same information)).

     10.8.  Subordination  Not Affected,  etc. The terms of this section 10, the
subordination  effected  hereby and the rights  created hereby of the holders of
the  Superior   Indebtedness  shall  not  be  affected  by  (a)  any  amendment,
modification  or waiver of or  supplement  to any Superior  Indebtedness  or any
agreement,   document  or  instrument  relating  thereto,   provided  that  such
amendment,  modification,  waiver  or  supplement  is not in  violation  of this
Agreement,  (b) any exercise or non-exercise of any right, power or remedy under
or in  respect of any  Superior  Indebtedness  (or any  security  or  collateral
therefor) or pursuant to any agreement,  document or instrument relating thereto
or (c) any consent,  release,  indulgence,  delay or other  action,  inaction or
omission, in respect of any Superior Indebtedness (or any security or collateral
therefor) or pursuant to any agreement, document or instrument relating thereto,
whether or not any holder of any Subordinated Indebtedness shall have had notice
or knowledge of any of the foregoing.

     10.9. Obligations Unimpaired.  The provisions of this section 10 are solely
for the  purpose of  defining  the  relative  rights of the  holders of Superior
Indebtedness on the one hand and the holders of Subordinated Indebtedness on the
other hand, and (a) subject to the rights,  if any, under this section 10 of the
holders of Superior Indebtedness, nothing in this section 10 shall (i) impair as
among  the  Obligors  and  the  holder  of  any  Subordinated  Indebtedness  the
obligation of the Obligors,  which is unconditional and absolute,  to pay to the
holder  thereof all amounts due thereon in accordance  with the terms thereof or
(ii) except as otherwise  provided in section  10.11,  prevent the holder of any



Subordinated Indebtedness from exercising all remedies available to such holder,
whether arising under the Operative Documents,  applicable law or otherwise, and
(b) no Person is entitled to any third party beneficiary rights or other similar
rights on  account of or under  this  section  10 other than the  holders of the
Superior  Indebtedness.  The  failure to make any  payment due in respect of the
Subordinated  Indebtedness  or to comply with any of the terms and conditions of
any of the  agreements,  documents and instruments  related to the  Subordinated
Indebtedness  by  reason  of any  provision  of this  section  10  shall  not be
construed as preventing  the  occurrence of any Default or Event of Default with
respect to the Subordinated Indebtedness.

     10.10. 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 (given as provided in this Agreement) from
the Operating  Company 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  10  to  recover  from  any  holder  of  the
Subordinated  Indebtedness any payment made in contravention of this section 10.
Each payment on the Subordinated  Indebtedness by the Operating Company shall be
deemed to constitute a representation of the Operating Company that such payment
is permitted to be paid by the Operating Company under this section 10.

     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.  In the event that such  holder of  Subordinated  Indebtedness
determines  in good faith that further  evidence is required with respect to the
right of any such Person to participate in any payment or distribution  pursuant
to this section 10, such holder of  Subordinated  Indebtedness  may request such
Person to furnish  evidence  to the  reasonable  satisfaction  of such holder of
Subordinated  Indebtedness as to any fact pertinent to the rights of such Person
under this  section 1, and if such  evidence  is not  furnished,  such holder of
Subordinated  Indebtedness may defer any payment to such Person pending judicial
determination as to the right of such Person to receive such payment.

     10.11.  Limitation  on Right of  Action.  Notwithstanding  anything  to the
contrary  contained in this  Agreement,  the Notes or any of the other Operative
Documents,  the holders of the  Subordinated  Indebtedness  agree  that,  if any
Superior   Indebtedness  is  outstanding,   the  holders  of  the   Subordinated
Indebtedness  will not exercise any right or remedy available to them on account
of any  Default  or Event of Default  (other  than the right to  accelerate  the
Subordinated  Indebtedness in accordance with the terms thereof and the right to
exercise any of the  Warrants) at any time at which  payments may not be made in



respect of the Subordinated  Indebtedness under section 10.4(a) unless and until
the first to occur of (a) the  holder or holders  of any  Superior  Indebtedness
shall have commenced  appropriate  proceedings (judicial or nonjudicial) for the
enforcement of their rights and remedies, including, without limitation, (i) any
action by any holder of any Superior Indebtedness against or with respect to any
Obligor to seek collection, or enforce collection, of any Superior Indebtedness,
or (ii) any exercise by any holder of any Superior  Indebtedness of any right to
foreclose on any security  interest or to sell any collateral or to exercise any
set-off or similar  right,  (b) 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
either  Company  or any of  their  respective  Subsidiaries  (other  than by the
holders of the Subordinated Indebtedness), or (c) an Event of Default shall have
occurred and shall have continued uncured and unwaived for a period of 150 days,
provided that, in any event,  the holders of the  Subordinated  Indebtedness may
commence any legal proceeding or take any other appropriate action if and to the
extent necessary to prevent the imminent  expiration of any applicable period of
limitations or the loss of any right under any applicable statute of limitations
or other law.

11.   Registration, etc.

      11.1. Shelf Registration.

          (a) As soon as  practicable  following the Closing  Date,  the Holding
     Company shall prepare and file with the Commission a registration statement
     on Form S-3 with respect to all of the Registrable Shares and shall use its
     best efforts to cause such  registration  statement to become  effective as
     soon  as  practicable,  but in any  event  not  later  than  the  one  year
     anniversary  of the Closing Date, so as to permit the sale to the public of
     the Registrable Shares through such methods and means as shall be specified
     in such  registration  statement  at the  direction  of the  holders of the
     Registrable  Shares. The Holding Company shall use its best efforts to keep
     such  registration  statement  current and effective with respect to all of
     the  Registrable  Shares by such action as may be necessary or appropriate,
     including,  without limitation, the filing of post-effective amendments and
     supplements,  until  the  earlier  of (i)  the  second  anniversary  of the
     effectiveness of the registration  statement and (ii) the date on which all
     of the  Registrable  Shares  have been sold to the  public  pursuant  to an
     effective  registration  statement or in  accordance  with Rule 144 (or any
     similar provision then in force) under the Securities Act. In addition,  if
     at any time and from time to time prior to July 12,  2006,  a  registration
     statement  on Form S-3 is not  effective  with  respect to the  Registrable
     Shares  of  any  holder  thereof,  upon  the  request  of  such  holder  of
     Registrable  Shares,  the Holding  Company  shall prepare and file with the
     Commission  a  registration  statement  on Form  S-3 with  respect  to such
     holder's Registrable Shares (and the Registrable Shares of any other holder
     thereof who shall notify the Holding  Company,  within 10 days of receiving
     the notice referred to below in this Section 11.1(a), that it requests that


     its  Registrable  Shares be included in such  registration  statement)  and
     shall use its best efforts to cause such  registration  statement to become
     effective as soon as practicable  following each such request of any holder
     of  Registrable  Shares,  so as to  permit  the sale to the  public of such
     Registrable  Shares through such methods and means as shall be specified in
     such  registration  statement at the  direction of the holder or holders of
     75% of the  Registrable  Shares to be  included in such  registration.  The
     Holding  Company  shall  use its best  efforts  to keep  such  registration
     statement  current and  effective  with  respect to all of the  Registrable
     Shares  included in such  registration  statement  by such action as may be
     necessary or  appropriate,  including,  without  limitation,  the filing of
     post-effective  amendments  and  supplements,  until the earlier of (i) the
     second anniversary of the effectiveness of such registration  statement and
     (ii) the date on which all of the Registrable  Shares have been sold to the
     public  pursuant to an effective  registration  statement or in  accordance
     with Rule 144 (or any similar provision then in force) under the Securities
     Act. Immediately  following its receipt of any holder's request to register
     Registrable  Shares,  the Holding Company shall notify each other holder of
     Registrable  Shares.  The Holding Company may be required  pursuant to this
     Section 11.1 to file (and keep effective) such  registration  statements on
     any number of occasions by the several holders of Registrable Shares.

          (b) The obligations of the Holding Company under this section 11.1 are
     subject to the following terms:

               (i) the Holding  Company  shall not  include in the  registration
          effected   pursuant  to  this  section   11.1  any  other   securities
          (including,  without  limitation,  any to be  issued  and  sold by the
          Holding  Company),  without the prior written consent of the holder or
          holders  of 75% of the  Registrable  Shares  to be  included  in  such
          registration; and

               (ii) the  Holding  Company  shall pay all  Registration  Expenses
          related to such registrations effected pursuant to this section 11.1.

          (c) The Companies jointly and severally represent and warrant that the
     Holding  Company has and shall  continue at all times to satisfy all of the
     conditions  to the use of Form  S-3,  including,  without  limitation,  the
     timely  filing of all reports  required to be filed under the  Exchange Act
     during the twelve calendar months preceding the date in question.

      11.2. Incidental Registration.

          (a) If the  Holding  Company  at any time or from  time to time  shall
     determine to effect the  registration,  qualification  and/or compliance of
     any of its Shares  (whether in  connection  with an offering by the Holding
     Company or others)  (otherwise  than  pursuant to a  registration  effected



     pursuant to section 2 of the  Registration  Rights and  Holdback  Agreement
     dated as of July 12, 1996, by and between  Spectra-Physics  and the Holding
     Company  or a  registration  on a form  inappropriate  for an  underwritten
     public  offering or relating solely to securities to be issued in a merger,
     acquisition  of the  stock or  assets  of  another  entity  or in a similar
     transaction), then, in each such case, the Holding Company will:

               (i) promptly  give written  notice of the proposed  registration,
          qualification  and/or  compliance  (which shall  include a list of the
          jurisdictions  in which the  Holding  Company  intends to  register or
          qualify such  securities  under the applicable blue sky or other state
          securities  laws) to each holder of any Registrable  Shares;  and 

               (ii)  include  among  the  Shares  which  it  then  registers  or
          qualifies all Registrable  Shares specified by any holder thereof in a
          written request or requests, made within 30 days after receipt of such
          written notice from the Holding Company.

          (b) The obligations of the Holding Company under this section 11.2 are
     subject to the following terms:

               (i) the  Holding  Company  shall  pay all  Registration  Expenses
          related to any  registration,  qualification  or compliance  requested
          pursuant to this section 11.2; and

               (ii) if, in connection with any underwritten offering pursuant to
          this  section  11.2,  the  managing   underwriter(s)  shall  impose  a
          limitation on the number or kind of  securities  which may be included
          in any such registration  because,  in its reasonable  judgment,  such
          limitation is necessary to effect an orderly public distribution, then
          the Holding Company shall be obligated to include in such registration
          statement only such limited portion of the  Registrable  Shares (which
          may  be  none)  as is  determined  in  good  faith  by  such  managing
          underwriter,  provided  that, if any  securities are being offered for
          the  account of any  Person  other than the  Holding  Company  and the
          holders of the  Registrable  Shares,  the  reduction  in the number of
          Registrable Shares included in such registration shall not represent a
          greater  percentage  of the amount of  Registrable  Shares  originally
          requested  to be  registered  and sold in such  registration  than the
          lowest such percentage reduction imposed upon any other Person.

     11.3.  Permitted  Registration.  If and to the  extent  that any  holder or
holders of any  Registrable  Shares  shall have,  at the time of delivery of the
written request referred to in section 11.2, no present  intention of selling or
distributing  such securities,  the Holding Company shall be obligated to effect



the registration, qualification and compliance of such securities of such holder
or holders  only if and to the  extent,  in each case,  that such  registration,
qualification  and  compliance  are  at the  time  permitted  by the  applicable
statutes  or  rules  and   regulations   thereunder  or  the  practices  of  the
governmental authority concerned.

     11.4.   Registration   Procedures.   In  the  case  of  each  registration,
qualification  and/or  compliance  contemplated  by this section 11, the Holding
Company will keep the holder or holders of Registrable Shares advised in writing
as to the initiation of proceedings  for such  registration,  qualification  and
compliance and as to the completion  thereof,  and will advise each such holder,
upon  request,  of the progress of such  proceedings.  In addition,  the Holding
Company will follow  procedures  customarily  observed by issuers in  registered
public offerings,  and accord to the holder or holders of Registrable Shares all
rights (including,  without  limitation,  the right to perform  appropriate "due
diligence")   customarily   accorded  to  selling   stockholders   in  secondary
distributions and to managing  underwriters if the transaction in question is or
were an underwritten public offering. At the expense of the Holding Company, the
Holding  Company  will in the case of each  registration,  qualification  and/or
compliance  contemplated by this section 11 (a) take all necessary  action under
any applicable blue sky or other state  securities law to permit the sale and/or
distribution of the Registrable Shares pursuant thereto, all as requested by the
holder or holders of  Registrable  Shares  included  therein,  provided that the
Holding  Company shall not be required to so register or qualify the Registrable
Shares in any jurisdiction  if, solely as a result thereof,  the Holding Company
must qualify  generally to do business  therein or consent to general service of
process  therein,  (b) comply  with  applicable  requirements  of all regulatory
entities,  including, without limitation, the National Association of Securities
Dealers,  Inc.,  (c) furnish each holder of Registrable  Shares included therein
such number of registration statements,  prospectuses,  supplements, amendments,
offering  circulars and other documents  incidental  thereto as such holder from
time to time may reasonably  request,  (d) list all  Registrable  Shares on each
securities  exchange on which  securities  of the same class are then listed and
(e) furnish (or cause to be furnished) to each holder of Registrable Shares, all
undertakings,  agreements,  certificates,  opinions,  financial  statements  and
"comfort  letters" of the sort customarily  provided to selling  stockholders in
secondary distributions and to the managing underwriters,  if the transaction in
question is or were an underwritten public offering.  Each holder of Registrable
Shares will furnish to the Holding  Company upon request by the Holding  Company
such  information  regarding  such holder and any  distribution  of  Registrable
Shares   proposed  by  such  holder  as  may  be  required  to  consummate   any
registration, qualification and/or compliance contemplated by this section 11.

     11.5.  Indemnification.  Without limiting the generality of section 21, the
Companies  will jointly and severally  indemnify,  defend and hold harmless each
holder of Registrable Shares included in any registration,  qualification and/or
compliance  contemplated  by  this  section  11 and  each  underwriter  of  such
securities,  and  each  Person,  if any,  who  controls  each  such  holder  and
underwriter  within the  meaning of the  Securities  Act,  and their  respective



directors,  officers,  employees,  agents,  advisors and  Affiliates  (each,  an
"Indemnified  Person"),  to the fullest extent  enforceable under applicable law
against  all claims,  losses,  damages  and  liabilities  (or actions in respect
thereof)  arising out of or based on any untrue  statement  (or  alleged  untrue
statement)  of  a  material  fact  contained  in  any  registration   statement,
prospectus,  supplement,  amendment, offering circular or other document related
to any  registration,  qualification  or  compliance or any omission (or alleged
omission)  to state  therein a material  fact  required to be stated  therein or
necessary to make the statements  therein not  misleading,  or any violation (or
alleged  violation) of the Securities Act or other securities laws in connection
with any such registration, qualification or compliance, and will reimburse each
such Indemnified Person for any legal or any other expenses  reasonably incurred
in connection with  investigating  and/or  defending  (and/or  preparing for any
investigation or defense of) any such claim, loss, damage, liability,  action or
violation;  provided that the  Companies  will not be liable in any such case to
any such  Indemnified  Person if, but only to the extent  that,  any such claim,
loss, damage,  liability,  action, violation or expense is finally determined to
arise out of or result from any untrue  statement  in or omission  from  written
information  furnished to the Holding  Company by an instrument duly executed by
such  Indemnified  Person and stated to be  specifically  for use therein.  Each
holder of  Registrable  Shares  will,  if  securities  held by such  holder  are
included in a  registration  effected  pursuant to this  section 11,  indemnify,
defend and hold harmless the Holding Company, each of its directors and officers
who signs the related  registration  statement,  and each  Person,  if any,  who
controls the Holding Company within the meaning of the Securities  Act,  against
all claims,  losses,  damages and  liabilities  (or actions in respect  thereof)
arising out of or based on any untrue statement (or alleged untrue statement) of
a  material  fact  contained  in any such  registration  statement,  prospectus,
supplement,  amendment,  offering circular or other document or any omission (or
alleged omission) to state therein a material fact required to be stated therein
or necessary to make the statements  therein not misleading,  and will reimburse
the Holding Company and such directors, officers or Persons for any legal or any
other expenses reasonably incurred in connection with investigating or defending
(and/or  preparing for any  investigation  or defense of) any such claim,  loss,
damage, liability or action, in each case to the extent, but only to the extent,
that such untrue statement (or alleged untrue statement) or omission (or alleged
omission) was made in (or omitted from) such registration statement, prospectus,
supplement,  amendment, offering circular or other document in reliance upon and
in conformity  with written  information  furnished to the Holding Company by an
instrument  duly executed by such holder and stated to be  specifically  for use
therein;  provided that the liability of any such holder under this section 11.5
shall be limited to the net sales proceeds actually received by such holder as a
result of the sale by it of securities in such registration.


     11.6. Restrictions on Other Agreements.  The Holding Company will not grant
any right relating to the registration of its securities if the exercise thereof
interferes  with or is inconsistent  with or will delay (or could  reasonably be
expected to interfere  with or be  inconsistent  with or delay) the exercise and
enjoyment  of any of the rights  granted  under this  section  11,  without  the



written consent of holders of 75% or more of (34) the Registrable  Shares at the
time issued and/or issuable,  which consent may be given or withheld in the sole
discretion  of such  holders.  The  Holding  Company  will not permit any of its
Subsidiaries to effect,  or to grant any right relating to, the  registration of
its securities.

12.   Put Rights.

     12.1.  Put Rights.  Each holder of Put  Securities (as defined below) shall
have the right to require the  Companies  to purchase  all or any portion of the
Put Securities owned by such holder  concurrently with the occurrence of any Put
Event  (as  defined  below),  in each  case at a  purchase  price  equal  to the
aggregate Put Price (as defined below) for such Put Securities. Each such holder
may  exercise  such  option  by  delivering  to the  Companies  a notice (a "Put
Notice")  specifying  that  the  Put  Securities  therein  described  are  to be
purchased  by the  Companies  and,  if the  Underlying  Securities  are not then
Publicly  Traded,  specifying the appraiser (first referred to in the definition
of Fair Value below) that shall  determine the Fair Value of the Put Securities.
Upon  receipt  of any  such Put  Notice  from a holder  of Put  Securities,  the
Companies  shall be  obligated,  jointly  and  severally,  to  purchase  the Put
Securities  specified  in such Put  Notice on the date upon which such Put Event
shall occur (the "Put Closing Date"),  unless in any case the Companies and such
holder agree to a different  date.  The closing for any payment of the Put Price
due to any holder of Put  Securities  under this section 12.1 shall occur at the
principal office of the Companies, unless the Companies and such holder agree to
a different  location,  and the aggregate Put Price shall be paid in immediately
available  funds  against  delivery  of the  certificates  evidencing  such  Put
Securities  as are to be purchased  from such holder at such  closing.  Promptly
after receipt by the Companies of a Put Notice from a holder of Put  Securities,
the Companies will notify each other holder of Put Securities of receipt of such
Put Notice and thereafter shall furnish to each holder such information relating
to the same as such holder may request  from time to time.  The  Companies  will
notify each holder of Put  Securities of the occurrence of any event which will,
or could  reasonably be expected to, result in a Put Event at least 30 days (but
not more than 60 days) prior to the occurrence of such Put Event.  The Companies
shall not permit a Put Event to be consummated unless the notice required by the
preceding  sentence  with  respect  to such  Put  Event  has been  delivered  in
accordance with such preceding sentence.

     12.2. Defined Terms. As used herein, the following terms have the following
respective meanings:

          "Current  Market  Price"  of any  Underlying  Security  as of any date
     herein specified shall mean the average of the daily closing prices for the
     30  consecutive  trading days  commencing 45 trading days before the day in
     question.  The closing  price for each day shall be (a) if such  Underlying
     Security  is listed or  admitted  for  trading on any  national  securities
     exchange, the last sale price of such Underlying Security,  regular way, or



     the  average of the closing  bid and asked  prices  thereof if no such sale
     occurred,  in each case as officially reported on the principal  securities
     exchange  on  which  such  Underlying  Security  is  listed,  or (b) if not
     reported as  described  in clause  (a),  the average of the closing bid and
     asked prices of such Underlying Security in the over-the-counter  market as
     shown by the National  Association of Securities  Dealers,  Inc.  Automated
     Quotation  System,  if so quoted, as reported by any member firm of the New
     York Stock Exchange selected by the Companies.

          "Fair Value" shall mean the fair value of the appropriate Put Security
     as determined in accordance with generally  accepted  financial practice by
     an independent  appraiser of recognized  national  standing selected by the
     holders of a majority of the Put  Securities  requested  to be  repurchased
     (provided such appraiser is reasonably satisfactory to the Companies).  The
     Companies shall use their best efforts to enable the independent  appraiser
     to  provide  its  determination  not  later  than  10  days  following  its
     selection.  Each such  determination  of Fair  Value  shall be set forth in
     writing and shall be  conclusive  and binding on the  Companies  and on the
     holders of the Put Securities to be  repurchased.  The Companies  shall pay
     all of the expenses  incurred in connection  with each such  determination,
     including, without limitation, the expenses of each appraiser.

          "Publicly   Traded"  shall  mean,   with  respect  to  the  Underlying
     Securities or the equity  securities  referred to in the definition of "Put
     Event",  on any date,  listed  or  admitted  for  trading  on any  national
     securities  exchange  or  quoted  on  the  over-the-counter  market  of the
     National  Association  of  Securities  Dealers,  Inc.  Automated  Quotation
     System,  in each case on such date and during the immediately  preceding 45
     consecutive  days and having an average  daily  trading  volume of not less
     than 78,500 during such period.

          "Put Event" shall mean (a) the merger or  consolidation of the Holding
     Company or any of its Material  Subsidiaries  with or into  another  Person
     (other than a merger of the Holding  Company with or into  another  Person,
     the sole  purpose  and  result of which is to change  the  jurisdiction  of
     incorporation of the Holding Company to another state of the United States)
     which does not have a class of Publicly Traded equity securities registered
     under the  Exchange Act and where the  consideration  to be received by the
     holders of the Holding  Company's  Shares in connection with such merger or
     consolidation  does  not  consist  solely  of cash  payable  in  full  upon
     consummation of such merger or consolidation,  or (b) the sale, transfer or
     other   disposition  by  the  Holding   Company  or  any  of  its  Material
     Subsidiaries of all or any substantial part of its properties and assets to
     another  Person  for  consideration  which (i) is other  than (A)  Publicly
     Traded equity securities  registered under the Exchange Act and/or (B) cash
     and (ii) is then  distributed to the stockholders of the Holding Company or
     the holders of Superior Indebtedness.

          "Put Price" at any date,  as applied to any Put  Security,  shall mean
     (i) if the  Underlying  Securities are not then Publicly  Traded,  the Fair



     Value thereof as of the date of occurrence of the  applicable Put Event and
     (ii) if the  Underlying  Securities are then Publicly  Traded,  the Current
     Market Price  thereof as of the date of occurrence  of the  applicable  Put
     Event.  The Put Price of any Warrant shall be reduced by an amount equal to
     the  amount  payable  upon  exercise  thereof  (if  and to the  extent  not
     otherwise paid to the Holding Company).

          "Put   Securities"   shall  mean  the  Warrants  and  the   Underlying
     Securities, each of which is a "Put Security".

     12.3 Continued Effect.  The provisions of this section 12 are applicable to
successive  Put  Events.  No  failure  on the  part  of any  holder  of the  Put
Securities to exercise any right under this section 12 arising on account of any
Put Event shall affect or impair any other right of such  holder,  in respect of
the Put  Securities or  otherwise,  under any of the  Operative  Documents.  The
covenants  contained in this section 12 shall  continue in effect so long as any
Put  Securities  are  outstanding  and,  without  limiting the generality of the
foregoing, shall survive the payment, prepayment and/or replacement of any other
Securities and any merger,  consolidation,  recapitalization,  sale of assets or
other similar  transaction or event  involving the Holding Company and/or any of
its Subsidiaries.

13.   Board Inspection Rights.

          (a) At any  reasonable  time and from  time to time,  upon  reasonable
     notice,  the  Companies  will permit any holder of the Notes or Warrants or
     any agents or representatives  thereof,  to examine and make abstracts from
     any  resolutions  and  consents  of, and any minutes  and other  records of
     meetings of, the respective boards of directors (and committees thereof) of
     the Holding  Company  and its  Subsidiaries,  and to discuss  the  affairs,
     finances and accounts of the Holding Company and its Subsidiaries  with any
     of their directors.

          (b) The Holding  Company  will meet at least once each  calendar  year

     Subsidiary  of the  Holding  Company or of all or any  substantial  part of
     their  respective  properties  and such  custody  or  control  shall not be

     option or right), if the aggregate  outstanding  amount thereof (and of any
     other  Indebtedness or other  obligation as to which the Holding Company or

     discharge any covenant, condition or obligation in any agreement,  document
     or  instrument  evidencing,  securing or relating to such  Indebtedness  or
     other  obligation,  if the  effect  of any such  failure  of the  character
     described  in this  clause (i) is to cause,  or permit any other  Person to
     cause,  any payment in respect thereof in an aggregate amount of $2,000,000
     or more to become due and payable,  or (ii) any such  Indebtedness or other

     which made;


          (k) if,  at any time,  this  Agreement  or any of the other  Operative
     Documents  shall  for any  reason  (other  than the  scheduled  termination
     thereof in accordance with its terms) expire,  fail to be in full force and
     effect or be disaffirmed,  repudiated, cancelled, terminated or declared to
     be unenforceable, null and void;

          (l) if (i)  any  Plan  shall  fail  to  satisfy  the  minimum  funding

     "amount of  unfunded  benefit  liabilities"  (within the meaning of section

     IV of ERISA,  shall  exceed  $250,000,  (iv)  either  Company  or any ERISA
     Affiliate  shall  have  incurred  or is  reasonably  expected  to incur any
     liability  pursuant  to Title I or IV of ERISA or the penalty or excise tax

     Company or any Subsidiary of either Company thereunder;  and any such event
     or events described in clauses (i) through (vi) above,  either individually
     or together with any other such event or events,  has resulted in, or could
     reasonably be expected to result in a Material Adverse Change; or

          (m) if (i) any Person or two or more Persons  acting in concert  shall
     have acquired beneficial ownership (within the meaning of Rule 13d-3 of the

     of the Holding Company (or other  securities  convertible  into such Voting
     Stock)  representing 30% or more of the combined voting power of all Voting
     Stock  of  the  Holding  Company;  (ii)  during  any  period  of  up  to 24
     consecutive months,  commencing before or after the date of this Agreement,

     exercise,   directly  or  indirectly,  a  controlling  influence  over  the
     management or policies of the Holding Company;


then,  in the  case  of an  Event  of  Default  of the  character  described  in
subdivisions  (a), (b), (c), (d), (h), (i), (j), (k), (l) or (m) of this section
16.1 and at the  option of the  holder or  holders  of 25% or more in  aggregate
principal  amount of the Notes at the time  outstanding  (excluding any Notes at
the time owned by either Company or any Affiliate of either Company),  exercised
by written  notice to the  Operating  Company,  the principal of all Notes shall
forthwith  become due and  payable,  together  with  interest  accrued  thereon,
without presentment,  demand,  protest or other notice of any kind, all of which
are hereby expressly waived,  and the Operating Company shall forthwith upon any
such acceleration pay to the holder or holders of all the Notes then outstanding
(i) the entire  principal  of and  interest  accrued  on the Notes,  and (ii) in
addition, to the extent permitted by applicable law, an amount equal to the Make
Whole Amount as liquidated  damages and not as a penalty;  provided that, in the
case of an Event of Default of the character  described in  subdivisions  (a) or
(b) of this section 16.1 and  irrespective of whether all of the Notes have been
declared  due and  payable by the holder or holders of 25% or more in  aggregate
principal amount of the Notes at the time  outstanding,  any holder of Notes who
or which has not  consented  to any waiver with respect to such Event of Default
may, at the option of such holder,  by written notice to the Operating  Company,
declare all Notes then held by such holder to be, and such Notes shall thereupon
become,  forthwith  due and payable,  together with  interest  accrued  thereon,
without presentment,  demand,  protest or other notice of any kind, all of which
are hereby expressly waived,  and the Operating Company shall forthwith upon any
such  acceleration  pay to such holder (i) the entire  principal of and interest
accrued  on such  Notes,  and  (ii) in  addition,  to the  extent  permitted  by
applicable  law, an amount equal to the Make Whole Amount as liquidated  damages
and not as a  penalty;  provided,  further,  that,  in the  case of an  Event of
Default of the  character  described  in  subdivisions  (e),  (f) or (g) of this
section 16.1, the principal of all Notes shall forthwith become due and payable,
together with interest  accrued thereon  (including any interest  accruing after
the commencement of any action or proceeding under the federal  bankruptcy laws,
as now or hereafter  constituted,  or any other  applicable  domestic or foreign
federal or state  bankruptcy,  insolvency  or other  similar  law, and any other
interest that would have accrued but for the  commencement  of such  proceeding,
whether or not any such  interest  is allowed  as an  enforceable  claim in such
proceeding),  without presentment,  demand, protest or other notice of any kind,
all of which are  hereby  expressly  waived,  and the  Operating  Company  shall
forthwith  upon any such  acceleration  pay to the  holder or holders of all the
Notes then  outstanding (i) the entire  principal of and interest accrued on the
Notes,  and (ii) in  addition,  to the extent  permitted by  applicable  law, an
amount  equal  to the Make  Whole  Amount  as  liquidated  damages  and not as a
penalty.

     Notwithstanding the foregoing provisions,  at any time after the occurrence
of any Event of Default and of notice thereof,  if any, by any holder or holders
of Notes and before any  judgment,  decree or order for payment of the money due
has been  obtained  by or on behalf of any holder or  holders of the Notes,  the
Required  Holders of the Notes by written notice to the Operating  Company,  may
rescind and annul such Event of Default  and/or  notice of such Event of Default
and the  consequences  thereof with respect to all of the Notes  (including  any
Notes  which were  accelerated  pursuant to the first  proviso in the  preceding



paragraph  by any  holder or  holders  on  account of an Event of Default of the
character described in subdivision (a) or (b) of this section 16.1) if:

     (1) the Operating Company has paid a sum sufficient to pay

          (A) all  overdue  installments  of  interest  on all Notes at the rate
     specified in the Notes;

          (B) the  principal of (and  premium,  if any, on) any Notes which have
     become due  otherwise  than by such Event of Default or notice  thereof and
     interest thereon at the rate specified in such Notes; and

          (C) to the extent that  payment of such  interest is lawful,  interest
     upon overdue interest at the rate specified in such Notes; and

     (2) all Defaults and Events of Default,  other than the  non-payment of the
principal of Notes which have become due solely by such acceleration,  have been
cured or waived as provided in section 19.

No such  rescission  shall  affect  any  subsequent  default or impair any right
consequent thereon.

     16.2. Suits for Enforcement,  etc. Subject to the provisions of section 10,
in case any one or more of the Events of Default specified in section 16.1 shall
have occurred,  and  irrespective  of whether any Notes have become or have been
declared  immediately due and payable under section 16.1, the holder of any Note
may proceed to protect  and  enforce  its rights  either by suit in equity or by
action at law, or both. The Companies  stipulate that the remedies at law of the
holder or holders of the  Securities  in the event of any default or  threatened
default by either Company in the  performance of or compliance with any covenant
or agreement in this Agreement or any of the other  Operative  Documents are not
and will not be adequate and that, to the fullest extent  permitted by law, such
terms may be  specifically  enforced  by a decree for the  specific  performance
thereof,  whether by an  injunction  against a violation  thereof or  otherwise.
Without  limiting the generality of the foregoing (and without  derogating  from
any  provision  contained  in  this  Agreement  or any of  the  other  Operative
Documents),  upon the  occurrence  and  during  the  continuance  of an Event of
Default,  the Required  Holders of each class of Securities shall have the right
to apply for and have a receiver  appointed  for each of the Companies and their
respective  Subsidiaries,  or any one or more of them,  by a court of  competent
jurisdiction in any action taken by any such holders to enforce their respective
rights and remedies  hereunder and under the other Operative  Documents in order
to manage, protect and preserve the assets of the Companies and their respective
Subsidiaries  and continue the  operation of the business of the  Companies  and
their  respective  Subsidiaries,  or to sell or  dispose  of the  assets  of the
Companies  and their  respective  Subsidiaries,  and to collect all revenues and
profits  thereof  and apply the same to the  payment of all  expenses  and other



charges of such  receivership,  including the compensation of the receiver,  and
the Companies hereby consent to such appointment without regard to the existence
of any  misfeasance  or  malfeasance  or the presence of any defenses that would
otherwise be available to such application.

     16.3. Remedies Cumulative.  No remedy conferred in this Agreement or in any
of the other Operative  Documents upon the holder of any Security is intended to
be  exclusive  of any other  remedy,  and each and every  such  remedy  shall be
cumulative  and shall be in addition to every other  remedy  given  hereunder or
thereunder  or now or  hereafter  existing  at law or in equity or by statute or
otherwise.

     16.4.  Remedies Not Waived. No course of dealing between either Company and
any of their  respective  Subsidiaries,  on the one hand,  and any holder of any
Security,  on the other hand,  and no delay by any such holder in exercising any
rights hereunder or under any of the other Operative  Documents shall operate as
a waiver of any rights of any such holder.

     16.5.  Application  of  Payments.  In case any one or more of the Events of
Default specified in section 16.1 shall have occurred, all amounts to be applied
to the prepayment or payment of any Notes,  shall be applied,  after the payment
of all  related  costs  and  expenses  incurred  by  the  holders  of the  Notes
(including, without limitation, reasonable compensation to any and all trustees,
liquidators,  receivers or similar  officials and reasonable fees,  expenses and
disbursements  of counsel) in such order of  priority  as is  determined  by the
Required Holders of the Notes.

17.  Registration,  Transfer  and  Exchange  of  Securities.  Securities  issued
hereunder shall be issued in registered  form. The Companies shall keep at their
principal executive office (which is now located at the address set forth at the
beginning  of this  Agreement),  registers  in which they shall  provide for the
registration and transfer of the Securities. The name and address of each holder
of the Securities  shall be registered in such  registers.  The Companies  shall
give to any  institutional  holder of any  Security  promptly  (but in any event
within 10 days) following request  therefor,  a complete and correct copy of the
names and addresses of all  registered  holders of the Securities and the amount
and kind of Securities held by each.  Whenever any Security or Securities  shall
be surrendered for transfer or exchange,  the applicable  Company at its expense
will execute and deliver in exchange  therefor a new Security or Securities  (in
such  denominations  and registered in such name or names as may be requested by
the holder of the  surrendered  Security or  Securities),  in the same aggregate
unpaid  principal  amount (in the case of the Notes) or exercisable for the same
aggregate  number  of  Shares  (in the  case  of any  Warrants)  or in the  same
aggregate  number  of  Shares  (in the  case  of any  Underlying  Security),  as
applicable, as that of the Security or Securities so surrendered.  The Companies
may treat the Person in whose name any  Security is  registered  as the owner of
such Security for all purposes.  


18.  Replacement  of  Securities.  Upon receipt by the  Companies of  reasonably
satisfactory evidence of the loss, theft,  destruction or mutilation of any Note
or  Warrant  and (in the  case of  loss,  theft or  destruction)  of  reasonably
satisfactory  indemnity,  and (in the case of mutilation) upon surrender of such
Note or Warrant,  the applicable Company at its expense will execute and deliver
in lieu of such Note or Warrant a new Note or Warrant of like tenor and,  in the
case of any new Note,  dated so as not to result in any loss of  interest.  Your
unsecured  agreement  to  indemnify  and/or  affidavit  and  that  of any  other
institutional holder shall constitute satisfactory indemnity and/or satisfactory
evidence of loss, theft or destruction for the purpose of this section 18.

19.   Amendment and Waiver.

          (a)  Any  term of  this  Agreement  and,  unless  explicitly  provided
     otherwise  therein,  of any of the other Operative  Documents may, with the
     consent of the  Companies,  be  amended,  or  compliance  therewith  may be
     waived,  in  writing  only,  by the  Required  Holders  of  each  class  of
     Securities entitled to the benefits of such term, provided that (i) without
     the consent of the holders of all of the Notes at the time outstanding,  no
     such amendment or waiver shall (A) change the amount of the principal of or
     any rate of interest on or the amount of any premium  payable  with respect
     to any of the Notes or change the  payment  terms of any of the Notes,  or,
     except as provided in the Notes, subordinate the obligation of the Obligors
     to pay any amount due on the Notes to any other  obligation,  or (B) change
     the percentage of holders of Notes required to approve any such  amendment,
     effectuate any such waiver or accelerate payment of the Notes; (ii) without
     the consent of the holders of all of the Warrants and Underlying Securities
     at the time  outstanding,  no such amendment or waiver shall (A) modify any
     of the provisions of section 11 or section 12, or (B) change the percentage
     of holders of the Warrants and  Underlying  Securities  required to approve
     any such  amendment or effect any such waiver;  and (iii) no such amendment
     or waiver shall extend to or affect any obligation not expressly amended or
     waived or impair any right consequent thereon. Executed or true and correct
     copies  of any  amendment,  waiver or  consent  effected  pursuant  to this
     section 19 shall be delivered by the Companies to each holder of Securities
     forthwith  (but in any event not later than five Business  Days)  following
     the effective date thereof.

          (b) The  Companies  will  not,  directly  or  indirectly,  request  or
     negotiate for, or offer or pay any remuneration or grant any security as an
     inducement  for, any proposed  amendment or waiver of any of the provisions
     of this  Agreement  or any of the other  Operative  Documents  unless  each
     holder of the Securities (irrespective of the kind and amount of Securities
     then owned by it) shall be informed  thereof by the Companies  and, if such
     holder is  entitled  to the  benefit of any such  provision  proposed to be
     amended or waived,  shall be afforded the  opportunity of  considering  the
     same,  shall be supplied by the Companies  with  sufficient  information to



     enable it to make an informed  decision  with respect  thereto and shall be
     offered and paid such  remuneration  and granted such  security on the same
     terms.

          (c) In determining  whether the requisite  holders of Securities  have
     given any  authorization,  consent  or waiver  under this  section  19, any
     Securities  owned by either Company or any of their  respective  Affiliates
     shall be disregarded and deemed not to be outstanding.

20. Method of Payment of Securities.  Irrespective of any provision hereof or of
the  other  Operative  Documents  to the  contrary,  so long as you or any other
institutional  holder  shall  hold any  Security,  the  Companies  will make all
payments  on such  Security  to you or such  other  institutional  holder by the
method and at the  address  for such  purpose  specified  in Schedule I attached
hereto  or by  such  other  method  or at  such  other  address  as you or  such
institutional holder may designate in writing (given as provided in section 23),
without requiring any presentation or surrender of such Security, except that if
any Security shall be paid,  prepaid and/or  repurchased in full,  such Security
shall be surrendered to the applicable Company promptly following such payment, 
prepayment or repurchase and cancelled.


21. Expenses;  Indemnity. Whether or not the transactions contemplated by any of
the  Operative  Documents  shall be  consummated,  the  Companies,  jointly  and
severally,  will pay or cause to be paid (or reimbursed, as the case may be) and
will  defend,  indemnify  and hold  you (and  each  other  holder  of any of the
Securities)  and each of your (and such  other  holder's)  directors,  officers,
employees,  agents, advisors and Affiliates (each, an "Indemnitee") harmless (on
an after tax  basis) in  respect  of all  costs,  losses,  expenses  (including,
without  limitation,  the reasonable fees, costs,  expenses and disbursements of
counsel) and damages (collectively, "Indemnified Costs") incurred by or asserted
against any Indemnitee in connection with the negotiation,  execution, delivery,
performance  and/or  enforcement of this Agreement or any of the other Operative
Documents   (including,   without   limitation,   so-called  work-  outs  and/or
restructurings   and  all  amendments,   waivers  and  consents   hereunder  and
thereunder, whether or not effected) and/or the consummation of the transactions
contemplated  hereby and thereby or which may otherwise be related in any way to
this Agreement or any other  Operative  Documents or such  transactions  or such
Indemnitee's   relationship  to  either  Company  or  any  of  their  respective
Affiliates or any of their respective properties and assets, including,  without
limitation, any and all Indemnified Costs related in any way to the requirements
of any Environmental Laws (as the same may be amended,  modified or supplemented
from  time to  time) or to any  environmental  investigation,  assessment,  site
monitoring,  containment, clean up, remediation, removal, restoration, reporting
and  sampling,  whether or not  consented  to, or  requested or approved by, any
Indemnitee, and whether or not such Indemnified Cost is attributable to an event
or condition  originating from any properties or assets of either Company or any
of their respective Subsidiaries or any other properties previously or hereafter
owned, leased, occupied or operated by either Company or any of their respective



Subsidiaries.  Notwithstanding  the  foregoing,  the  Companies  shall  have any
obligation  to  an  Indemnitee  under  this  section  21  with  respect  to  any
Indemnified   Cost  which  is  finally   determined  by  a  court  of  competent
jurisdiction  to have  arisen  solely and  directly  as a result of the  willful
misconduct or bad faith of such Indemnitee.

22.  Taxes.  The  Companies  jointly and  severally  will pay all taxes and fees
(including interest and penalties),  including, without limitation, all issuance
and documentary stamp and similar taxes,  which may be payable in respect of the
execution  and  delivery  of this  Agreement  and  each of the  other  Operative
Documents.

23.  Communications.   All  communications   provided  for  herein  and,  unless
explicitly  provided otherwise therein,  in any of the other Operative Documents

their  respective  rights  or  obligations  hereunder  or under any of the other
Operative  Documents without the written consent of the Required Holders of each
class of Securities then outstanding.

26.   Purchase for Investment; ERISA.

          (a) You  represent and warrant (i) that you have been  furnished  with
     all information  that you have requested for the purpose of evaluating your
     proposed  acquisition of the Securities to be issued to you pursuant hereto
     and  (ii) that  you will acquire such  Securities  for your own account for
     investment  and not for  distribution  in any  manner  that  would  violate
     applicable securities laws, but without prejudice to your rights to dispose
     of such Securities or a portion thereof to a transferee or transferees,  in
     accordance  with such laws if at some future time you deem it  advisable to
     do so. The  acquisition  of such  Securities  by you at the  Closing  shall
     constitute  your   confirmation  of  the  foregoing   representations   and
     warranties.  You understand that such Securities are being sold to you in a
     transaction  which is  exempt  from the  registration  requirements  of the
     Securities  Act, and that,  in making the  representations  and  warranties
     contained  in  section  5.16,  the  Companies  are  relying,  to the extent
     applicable, upon your representations and warranties contained herein.



          (b) You represent that at least one of the following  statements is an
     accurate  representation as to each source of funds (a "Source") to be used
     by you to pay the purchase  price of the  Securities to be purchased by you
     hereunder:

               (i) the  Source is an  "insurance  company  general  account"  as
          defined in Section V(e) of Prohibited  Transaction  Exemption  ("PTE")
          95- 60 (issued July 12, 1995) and, except as you have disclosed to the
          Companies  in writing  pursuant  to this  section  (i),  the amount of
          reserves and liabilities for the general account  contract(s)  held by
          or on behalf of any employee benefit plan or group of plans maintained
          by the same employer or employee organization do not exceed 10% of the
          total reserves and  liabilities of the general  account  (exclusive of
          separate  account  liabilities)  plus surplus as set forth in the NAIC
          Annual Statement filed with the state of domicile of the insurer; or

               (ii) the Source is a separate  account  of an  insurance  company
          maintained  by you in which an employee  benefit  plan (or its related
          trust) has an interest, which separate account is maintained solely in
          connection  with your fixed  contractual  obligations  under which the
          amounts payable,  or credited,  to such plan and to any participant or
          beneficiary of such plan (including any annuitant) are not affected in
          any manner by the investment performance of the separate account; or

               (iii) the  Source  is  either  (A) an  insurance  company  pooled
          separate  account,  within the meaning of PTE 90-1 (issued January 29,
          1990), or (B) a bank collective investment fund, within the meaning of
          the PTE 91-38 (issued July 12, 1991) and, except as you have disclosed
          to the  Companies  in  writing  pursuant  to this  section  (iii),  no
          employee  benefit  plan or  group  of  plans  maintained  by the  same
          employer or employee  organization  beneficially owns more than 10% of
          all assets  allocated to such pooled  separate  account or  collective
          investment fund; or

               (iv)  the  Source  constitutes  assets  of an  "investment  fund"
          (within  the  meaning  of Part V of the QPAM  Exemption)  managed by a
          "qualified  professional  asset manager" or "QPAM" (within the meaning
          of Part V of the QPAM  Exemption),  no employee  benefit plan's assets
          that are included in such  investment  fund,  when  combined  with the
          assets of all other employee  benefit plans  established or maintained
          by the same employer or by an affiliate (within the meaning of Section
          V(c)(1)  of the  QPAM  Exemption)  of  such  employer  or by the  same
          employee  organization  and  managed by such  QPAM,  exceed 20% of the
          total client assets  managed by such QPAM, the conditions of Part I(c)
          and (g) of the QPAM  Exemption are  satisfied,  neither the QPAM nor a
          person



          controlling  or  controlled by the QPAM  (applying  the  definition of
          "control"  in Section  V(e) of the QPAM  Exemption)  owns a 5% or more
          interest  in either  Company  and  (A) the  identity  of such QPAM and
          (B) the names of all employee  benefit plans whose assets are included
          in such  investment  fund  have been  disclosed  to the  Companies  in
          writing  pursuant  to  this  section  (iv);  or 

               (v) the Source is a governmental plan; or

               (vi) the  Source  is one or more  employee  benefit  plans,  or a
          separate  account  or trust  fund  comprised  of one or more  employee
          benefit plans,  each of which has been  identified to the Companies in
          writing pursuant to this section (vi); or

               (vii) the Source does not include assets of any employee  benefit
          plan, other than a plan exempt from the coverage of ERISA.

     As  used  in  this  section  26(b),  the  terms  "employee  benefit  plan",
     "governmental  plan", "party in interest" and "separate account" shall have
     the respective  meanings  assigned to such terms in Section 3 of ERISA, and
     the term "QPAM Exemption" means PTE 84-14 (issued March 13, 1984).

27.  Governing  Law;  Jurisdiction;  Waiver of Jury Trial.  This  Agreement and,
unless  explicitly  provided  otherwise  therein,  each of the  other  Operative
Documents,  including  the  validity  hereof  and  thereof  and the  rights  and
obligations  of the parties  hereunder and  thereunder,  and all  amendments and
supplements  hereof and  thereof  and all waivers  and  consents  hereunder  and
thereunder,  shall be construed in accordance  with and governed by the domestic
substantive laws of the State of New York without giving effect to any choice of
law or conflicts of law  provision or rule that would cause the  application  of
the domestic  substantive laws of any other  jurisdiction.  Each Company, to the
extent that it may lawfully do so, hereby consents to service of process, and to
be sued, in the State of New York and in The Commonwealth of  Massachusetts  and
consents to the  jurisdiction  of the courts of the State of New York and of The
Commonwealth of  Massachusetts  and of the United States District Courts for the
Southern District of New York and for the District of Massachusetts,  as well as
to the  jurisdiction  of all  courts to which an appeal  may be taken  from such
courts,  for the purpose of any suit, action or other proceeding  arising out of
any  of  its  obligations  hereunder  or  thereunder  or  with  respect  to  the
transactions  contemplated  hereby or thereby,  and expressly waives any and all
objections  it may have as to venue in any such  courts.  Each  Company  further
agrees that a summons and complaint commencing an action or proceeding in any of
such courts shall be properly served and shall confer  personal  jurisdiction if
served personally or by certified mail to it at its address set forth in section
23 or as  otherwise  provided  under  the  laws of the  State of New York or The
Commonwealth  of  Massachusetts,   as  the  case  may  be.  Notwithstanding  the
foregoing,  each Company agrees that nothing  contained in this section 27 shall



preclude the  institution  of any such suit,  action or other  proceeding in any
jurisdiction   other  than  the  State  of  New  York  or  The  Commonwealth  of
Massachusetts.  EACH COMPANY  IRREVOCABLY WAIVES ALL RIGHT TO A TRIAL BY JURY IN
ANY SUIT,  ACTION OR OTHER  PROCEEDING  INSTITUTED BY OR AGAINST SUCH COMPANY IN
RESPECT  OF  ITS  OBLIGATIONS   HEREUNDER  OR  THEREUNDER  OR  THE  TRANSACTIONS
CONTEMPLATED HEREBY OR THEREBY.

28. Rule 144A. Each Company will take, or will cause to be taken, such action as
any holder of Securities may reasonably  request from time to time to facilitate
any  sale  or  disposition  by  any  such  holder  of  any  Securities   without
registration  under the  Securities Act and/or any  applicable  securities  laws
within the  limitation  of the  exemptions  provided  by any rule or  regulation
thereunder, including, without limitation, Rule 144A under the Securities Act.

29.  Miscellaneous.  The  headings  in this  Agreement  and in each of the other
Operative  Documents  are for purposes of reference  only and shall not limit or
otherwise  affect the meaning hereof or thereof.  This Agreement  (together with
the other Operative  Documents)  embodies the entire agreement and understanding
among  you  and  the  Companies  and   supersedes   all  prior   agreements  and
understandings  relating to the subject matter hereof.  Each covenant  contained
herein and in each of the other Operative  Documents shall be construed  (absent
an  express  provision  to the  contrary)  as being  independent  of each  other
covenant contained herein and therein,  so that compliance with any one covenant
shall  not  (absent  such an  express  contrary  provision)  be deemed to excuse
compliance with any other covenant. If any provision in this Agreement or in any
of the other  Operative  Documents  refers to any action taken or to be taken by
any Person, or which such Person is prohibited from taking, such provision shall
be  applicable,  whether  such action is taken  directly or  indirectly  by such
Person,  whether  or not  expressly  specified  in such  provision.  In case any
provision in this  Agreement or any of the other  Operative  Documents  shall be
invalid, illegal or unenforceable,  the validity, legality and enforceability of
the remaining  provisions shall not in any way be affected or impaired  thereby.
This Agreement and, unless explicitly  provided otherwise  therein,  each of the
other Operative Documents,  may be executed in any number of counterparts and by
the parties hereto or thereto, as the case may be, on separate  counterparts but
all such counterparts shall together constitute but one and the same instrument.
