     On June 14, 1996, the Registrant acquired two Illinois

     Registrant's common stock plus up to an additional $500,000
     in value of such stock at a later date subject to certain
     performance conditions.  Tek and PSR were under common
     ownership, consisting principally of Herbert L. Pavey and
     Julius Rothschild, the founders, and also including certain
     other employees.  Tek and PSR have operated a single

                  MERGER AGREEMENT AND PLAN OF REORGANIZATION

      Agreement entered  into  as of  June  14,  1996, by  and  among  Natural

Corp.,  an  Illinois corporation  and a  wholly-owned  Subsidiary of  NMS (the
"Acquisition Sub"), Tek-Nique, Inc., an Illinois corporation ("TEKnique"), and
Herbert  L.   Pavey   and  Julius   M.   Rothschild  (together,   the   "Major
Stockholders").  NMS, the Acquisition Sub, TEKnique and the Major Stockholders
are referred to collectively herein as the "Parties."

      This Agreement contemplates a  tax-free merger transaction in  which NMS
will  acquire  all of  the outstanding  capital  stock of  TEKnique  through a
reverse subsidiary  merger of the Acquisition Sub with and into TEKnique.  The
stockholders  of TEKnique will  receive capital stock  of NMS  in exchange for
their capital stock  of TEKnique.  It is intended  that this transaction shall
qualify for federal income tax purposes as a reorganization within the meaning
of Section 368(a) of the Code (as defined below) and that this Agreement shall
constitute a  "plan of reorganization" for  the purposes of Section  368(a) of
the  Code.    It  is  intended that  the  transaction  shall  be  recorded for
accounting purposes as a purchase.

      Now, therefore, in consideration of the premises and the mutual promises
herein  made, and  in consideration  of the  representations,  warranties, and
covenants herein contained, the Parties agree as follows.

Illinois Corporation Law.   TEKnique  shall be the  corporation surviving  the
Merger (the "Surviving Corporation").

      (b)   Actions  at the  Closing.   At  the  closing of  the  transactions
contemplated  by  this  Agreement (the  "Closing")  on  the  date hereof  (the
"Closing Date"), (i) TEKnique will deliver  to NMS and the Acquisition Sub the
various certificates, instruments,  and documents referred to in  Section 5(a)
below,  (ii) NMS and the Acquisition Sub  will deliver to TEKnique the various
certificates, instruments,  and documents referred  to in Section  5(b) below,
and  (iii) TEKnique and  the Acquisition Sub  will file with  the Secretary of

as Exhibit 2(b) (the "Articles of Merger").

      (c)   Effect of Merger.

            (i)   General.  The Merger shall become effective at the time (the
      "Effective  Time") TEKnique and the Acquisition Sub file the Articles of

            





            


      Merger with the Secretary of State of the State of Illinois.  The Merger
      shall have  the effect set forth  in the Illinois Corporation  Law.  The
      Surviving  Corporation may, at any  time after the  Effective Time, take
      any action (including executing and delivering any document) in the name
      and  on behalf  of either TEKnique  or the  Acquisition Sub  in order to
      carry  out   and  effectuate  the  transactions   contemplated  by  this
      Agreement.

            (ii)  Articles of Incorporation.  The Articles of Incorporation of
      the Surviving Corporation shall be amended and restated at and as of the
      Effective  Time to  read as  did the  Articles  of Incorporation  of the
      Acquisition Sub immediately prior to the Effective Time (except that the
      name of the Surviving Corporation will remain unchanged).

            (iii) Bylaws.   The Bylaws of  the Surviving Corporation  shall be
      amended and restated at and as of the Effective Time to  read as did the
      Bylaws  of the Acquisition Sub  immediately prior to  the Effective Time
      (except  that   the  name  of  the  Surviving  Corporation  will  remain
      unchanged).

            (iv)  Directors  and Officers.  The directors  and officers of the
      Acquisition Sub shall become the directors and officers of the Surviving

      (vii) and Section 2(d) below.

            (vi)  Adjustments to Conversion Ratio.  The Conversion Ratio shall

      determined  to be  issuable pursuant  to Section  2(d)(ii) below  and as
      provided in Exhibit Section 2(d)(ii).

            (vii) Fractional Shares.   No fraction  of an NMS  Share shall  be
      issued, but in  lieu thereof each  holder of  TEKnique Shares who  would
      otherwise  be entitled to a fraction  of an NMS Share (after aggregating
      all   fractional  NMS  Shares  to  be  received  by  such  holder  after
      adjustment, if any, to the  Conversion Ratio as provided for  in Section
      2(c)(vi)) shall receive one additional NMS Share.

            (viii)      Conversion of Acquisition  Sub Shares.   At and as  of
      the Effective  Time, by virtue of  the Merger and without  any action on
      the part of any holder of any capital stock of the Acquisition Sub, each

      All Taxes owed by TEKnique (whether or not shown on any Tax Return) have
      been paid.   TEKnique is not currently the beneficiary  of any extension
      of time within which  to file any  Tax Return.  No  claim has ever  been
      made by an authority in a jurisdiction where TEKnique does  not file Tax
      Returns that it  is or may be subject to  taxation by that jurisdiction.
      There are  no Security Interests on  any of the assets  of TEKnique that

      Tax.

            (ii)  TEKnique has withheld  and paid all  Taxes required to  have
      been withheld and  paid in connection with amounts paid  or owing to any
      employee, independent contractor, creditor,  stockholder, or other third

            (iii) No   Stockholder  or   director  or  officer   (or  employee
      responsible for Tax matters) of TEKnique expects any authority to assess
      any  additional Taxes  for any  period for  which Tax Returns  have been
      filed.   There is  no dispute or  claim concerning any  Tax Liability of
      TEKnique either (A) claimed or raised by any authority in writing or (B)
      as to which any of the  Stockholders and the directors and officers (and
      employees responsible for Tax matters)  of TEKnique has Knowledge  based
      upon personal contact with any agent of such authority.  Section 3(k) of
      the  Disclosure Schedule  lists all  federal, state, local,  and foreign

      complete copies of  all federal income Tax Returns, examination reports,

                                8

      since December 31, 1990.

            (iv)  TEKnique  has  not  waived  any statute  of  limitations  in
      respect of Taxes or  agreed to any extension  of time with respect  to a
      Tax assessment or deficiency.

            (v)   TEKnique has  not filed a consent under  Code Section 341(f)
      concerning  collapsible  corporations.     TEKnique  has  not  made  any
      payments,  is  obligated to  make any  payments, or  is  a party  to any
      agreement that under certain circumstances could obligate it to make any
      payments that will not  be deductible under Code Section 280G.  TEKnique
      has  not been a United  States real property  holding corporation within
      the  meaning  of Code  Section  897(c)(2) during  the  applicable period
      specified in Code  Section 897(c)(1)(A)(ii).  TEKnique  has disclosed on
      its  federal income Tax Returns  all positions taken  therein that could
      give rise to a  substantial understatement of federal income  Tax within
      the meaning of  Code Section 6662.  TEKnique is not a  party to any  Tax
      allocation or  sharing agreement.  TEKnique (A) has not been a member of

      under Reg.  Section  1.1502-6 (or any similar provision of state, local,
      or  foreign  law),  as  a  transferee  or  successor,  by  contract,  or
      otherwise.

            (vi)  Intentionally Omitted.

            (vii) The unpaid  Taxes of TEKnique  (A) did  not, as of  the Most
      Recent  Fiscal Month End, exceed  the reserve for  Tax Liability (rather
      than  any  reserve for  deferred  Taxes  established  to reflect  timing
      differences between  book and Tax income)  set forth on the  face of the
      Most Recent Balance Sheet (rather than  in any notes thereto) and (B) do
      not exceed  that reserve as adjusted for the passage of time through the
      Closing Date in accordance with the past custom and practice of TEKnique
      in filing its Tax Returns.

            contemplated hereby;

                  (C)   no  party to  the lease  or sublease  is in  breach or
            default, and no event has occurred  which, with notice or lapse of

state any  material  fact  necessary  in  order to  make  the  statements  and

      4.    Representations  and Warranties  of NMS  and the  Acquisition Sub.
Each  of NMS and the Acquisition Sub  represents and warrants to TEKnique that

December 31, 1995.  The financial  statements included in  or incorporated  by
reference  into  these   Public  Reports  (including  the  related  notes  and

basis  throughout the periods covered thereby and present fairly the financial
condition of  NMS and  its  Subsidiaries as  of the  indicated  dates and  the

unliquidated,  and whether due or to  become due), including any liability for
taxes, except for (i) liabilities set forth  on the face of the balance  sheet
dated  as of  the Most  Recent Fiscal  Quarter End (rather  than in  any notes

Quarter End  in the Ordinary Course  of Business (none of  which results from,

      6.    Post-Closing  Agreements.    The  Parties agree  as  follows  with
respect to the period following the Closing.

      (a)   General.  In case at any time after the Closing any further action
is necessary to carry out the purposes of  this Agreement, each of the Parties
will take such further  action (including the  execution and delivery of  such
further  instruments and documents) as any other Party reasonably may request,
all  at  the  sole  cost  and expense  of  the  requesting  Party  (unless the
requesting  Party  is entitled  to  indemnification therefor  under  Section 7
below).  The Major Stockholders acknowledge  and agree that from and after the
Closing NMS will  be entitled to  possession of all documents,  books, records
(including Tax records), agreements,  and financial data of any  sort relating
to TEKnique.

      (b)   Litigation Support.   In the event  and for so  long as any  Party
actively  is contesting  or defending  against any  action, suit,  proceeding,
hearing, investigation, charge, complaint, claim, or demand in connection with
(i)  any transaction  contemplated  under this  Agreement  or (ii)  any  fact,
situation,   circumstance,  status,   condition,  activity,   practice,  plan,
occurrence,  event, incident,  action, failure  to act,  or transaction  on or
prior  to the Closing Date involving TEKnique,  each of the other Parties will
cooperate  with him or it  and his or  her counsel in the  contest or defense,
make available their personnel, and provide such testimony and access to their
books  and records  as shall be  necessary in  connection with  the contest or

                               23





            


defense, all at the sole cost and expense of the contesting or defending Party
(unless  the  contesting or  defending  Party is  entitled  to indemnification
therefor under Section 7 below).

      (c)   Transition.    Neither of  the  Major Stockholders  has  taken any
action that  is designed or  intended to have  the effect of  discouraging any
lessor, licensor, customer, supplier, or other business  associate of TEKnique
from  maintaining  the same  business  relationships with  TEKnique  after the
Closing as  it maintained with  TEKnique prior  to the Closing.   Each  of the
Major  Stockholders  will  refer  all   customer  inquiries  relating  to  the
businesses of TEKnique to NMS from and after the Closing.

      (d)   Confidentiality.   Each of  the Major Stockholders  will treat and
hold as  such all of the  Confidential Information, refrain from  using any of
the Confidential  Information except  in connection  with this  Agreement, and
deliver  promptly to  NMS or destroy,  at the  request and option  of NMS, all
tangible embodiments (and  all copies) of  the Confidential Information  which
are  in  his  or her  possession.   In  the  event  that either  of  the Major
Stockholders  is  requested  or required  (by  oral  question  or request  for
information  or documents  in any  legal proceeding,  interrogatory, subpoena,
civil  investigative demand, or similar process)  to disclose any Confidential
Information, that Major Stockholder will notify NMS promptly of the request or
requirement so  that NMS  may seek  an appropriate  protective order or  waive
compliance  with the provisions of this Section 6(d).  If, in the absence of a
protective  order or the  receipt of a  waiver hereunder, either  of the Major
Stockholders  is,  on  the  advice  of  counsel,  compelled  to  disclose  any
Confidential  Information to any tribunal  or else stand  liable for contempt,
that  Major  Stockholder may  disclose  the  Confidential Information  to  the
tribunal; provided, however, that  the disclosing Major Stockholder  shall use
his or  her reasonable best  efforts to obtain,  at the reasonable  request of
NMS, an order or other assurance that confidential treatment  will be accorded
to such portion of  the Confidential Information  required to be disclosed  as
NMS  shall  designate.    The foregoing  provisions  shall  not  apply to  any
Confidential  Information   which  is   generally  available  to   the  public
immediately prior to the time of disclosure.

      7.    Remedies for Breaches of This Agreement.

      (a)   Survival of Representations and  Warranties.  The  representations
and warranties made by  each of the Parties in this Agreement  shall be deemed
to have  been relied upon  by the other Parties  hereto and shall  survive the
Closing,  provided that  in  no event  shall  any Party  be  entitled to  seek
indemnification in respect  of any  breach of any  representation or  warranty
made herein (except any  made in Section 3(b)  or the last three  sentences of
Section 3(a) above, as to which such remedy shall not be so limited)  pursuant
to this  Section 7 unless the Party seeking indemnification has made a written
claim therefor pursuant to Section 9(h) below prior to January 1, 1998.




                               24






            

      (b)   Indemnification Provisions.

            (i)  In the  event TEKnique  or either  of the  Major Stockholders
      breaches (or in the event  any third party alleges facts that,  if true,
      would  mean TEKnique or either  of the Major  Stockholders has breached)
      any of its  or his representations, warranties,  and covenants contained
      herein, provided  that  NMS makes  a written  claim for  indemnification
      pursuant to Section  9(h) below prior to  January 1, 1998, then each  of
      the  Major Stockholders  agrees to  indemnify NMS  from and  against the
      entirety  of any Adverse Consequences  NMS may suffer  through and after
      the  date  of  the  claim  for indemnification  (including  any  Adverse
      Consequences NMS  may suffer after  December 31,  1997) resulting  from,
      arising out of, relating to, in  the nature of, or caused by  the breach
      (or  the alleged breach);  provided that,  in no  event shall  the Major
      Stockholders be liable  to an  amount which exceeds  the aggregate  fair
      market value  (determined on the basis  of the closing price  of the NMS
      Shares on the date of the respective issuances) of the NMS Shares issued
      to all of the stockholders of TEKnique in consideration for the exchange
      of all of the TEKnique Shares.  

            (ii)  In the event  NMS breaches (or in the  event any third party
      alleges  facts that, if  true, would mean  NMS has breached)  any of its
      representations,  warranties, and  covenants contained  herein, provided
      that  the  Representatives makes  a  written  claim for  indemnification
      against NMS pursuant  to Section  9(h) below prior  to January 1,  1998,
      then NMS agrees  to indemnify each  of the Major  Stockholders from  and
      against the  entirety of any Adverse Consequences the Major Stockholders
      may suffer through and after the  date of the claim for  indemnification
      (including  any Adverse  Consequences the  Stockholder may  suffer after
      December 31, 1997) resulting  from, arising out of, relating to,  in the
      nature of, or caused by the breach (or the alleged breach).

      (c)   Matters Involving Third Parties.

            (i)   If any third party shall notify any Party (the  "Indemnified
      Party")  with respect to  any matter (a  "Third Party  Claim") which may
      give rise to  a claim for  indemnification against any other  Party (the
      "Indemnifying Party") under this  Section 7, then the  Indemnified Party
      shall  promptly  notify  each  Indemnifying Party  thereof  in  writing;
      provided, however, that no delay on the part of the Indemnified Party in
      notifying any  Indemnifying Party  shall relieve the  Indemnifying Party
      from any obligation hereunder unless (and then solely to the extent) the
      Indemnifying Party thereby is prejudiced.

            (ii)  Any  Indemnifying Party  will have  the right to  defend the
      Indemnified  Party against  the Third  Party Claim  with counsel  of its
      choice reasonably satisfactory to  the Indemnified Party so long  as (A)
      the Indemnifying Party notifies the Indemnified Party in  writing within
      15 days  after the Indemnified Party has given notice of the Third Party
      Claim  that the Indemnifying Party  will indemnify the Indemnified Party

                               25





            


      from  and  against   the  entirety  of  any   Adverse  Consequences  the
      Indemnified Party may  suffer resulting from,  arising out of,  relating
      to, in  the nature  of,  or caused  by the  Third Party  Claim, (B)  the
      Indemnifying  Party  provides  the   Indemnified  Party  with   evidence
      reasonably  acceptable to  the Indemnified  Party that  the Indemnifying
      Party  will have  the financial  resources to  defend against  the Third
      Party Claim  and fulfill its indemnification  obligations hereunder, (C)
      the  Third Party Claim involves only money  damages and does not seek an
      injunction or other equitable  relief, (D) settlement of, or  an adverse
      judgment with  respect to, the  Third Party  Claim is not,  in the  good
      faith  judgment  of  the  Indemnified  Party,   likely  to  establish  a
      precedential  custom or  practice materially  adverse to  the continuing
      business  interests of the  Indemnified Party, and  (E) the Indemnifying
      Party  conducts  the  defense of  the  Third  Party  Claim actively  and
      diligently.

            (iii) So long as the Indemnifying Party is conducting the  defense
      of the Third Party Claim in  accordance with Section 7(c)(ii) above, (A)
      the  Indemnified Party may retain  separate co-counsel at  its sole cost
      and expense and participate in the defense of the Third Party Claim, (B)
      the Indemnified Party  will not consent to the entry  of any judgment or
      enter into  any settlement with respect to the Third Party Claim without
      the prior written consent  of the Indemnifying Party (not to be withheld
      unreasonably),  and (C) the Indemnifying  Party will not  consent to the
      entry of any judgment or  enter into any settlement with respect  to the
      Third Party Claim without  the prior written consent of  the Indemnified
      Party (not to be withheld unreasonably).

            (iv)  In the event any of the conditions in Section 7(a)(ii) above
      is or becomes unsatisfied, however, (A) the Indemnified Party may defend
      against, and  consent to the  entry of  any judgment or  enter into  any
      settlement  with respect  to, the  Third  Party Claim  in any  manner it
      reasonably  may deem  appropriate (and  the Indemnified  Party need  not
      consult  with, or  obtain any  consent from,  any Indemnifying  Party in
      connection therewith),  (B) the Indemnifying Parties  will reimburse the
      Indemnified Party promptly and  periodically for the costs of  defending
      against the Third Party Claim  (including reasonable attorneys' fees and
      expenses), and (C) the Indemnifying Parties  will remain responsible for
      any  Adverse Consequences  the  Indemnified Party  may suffer  resulting
      from,  arising out of, relating  to, in the nature of,  or caused by the

claim  is for  judgments, damages,  penalties, fines,  costs, amounts  paid in

complaint, claim, or  demand is pursuant to this Agreement, applicable law, or
otherwise).

      with the  filing of Tax  Returns for TEKnique  for all periods  after or
      prior to the Closing Date which are filed after the Closing Date and any
      audit,  litigation  or other  proceeding with  respect  to Taxes.   Such

      employees available on a mutually convenient basis to provide additional

      extensions thereof) of the  respective taxable periods, and to  abide by
      all record retention agreements entered  into with any taxing authority,
      and  (B) to  give the  other party  reasonable written  notice prior  to
      transferring,  destroying or discarding any such  books and records and,
      if NMS so requests, the Stockholders shall allow NMS  to take possession
      of such books and records.

            (ii)  NMS and the Major  Stockholders further agree, upon request,
      to use  their best efforts to  obtain any certificate or  other document
      from any governmental authority or any other Person  as may be necessary
      to  mitigate,  reduce  or  eliminate  any  Tax  that  could  be  imposed
      (including,  but  not  limited  to,  with respect  to  the  transactions
      contemplated hereby).

            (iii) NMS and the Major  Stockholders further agree, upon request,
      to provide the other party with all information that either party may be
      required to report pursuant to Section 6043 of the Code and all Treasury
      Department Regulations promulgated thereunder.

      (b)   Tax Sharing  Agreements.   All tax  sharing agreements  or similar
agreements with respect to or involving TEKnique shall be terminated as of the
Closing Date and, after the Closing  Date, TEKnique shall not be bound thereby
or have any liability thereunder.


                               27





            


      (c)   Certain Taxes.   All transfer, documentary, sales,  use, stamp and
other such Taxes  and fees (including any penalties and  interest) incurred in
connection  with this Agreement,  shall be paid by  Stockholders when due, and
Stockholders will, at  their own expense,  file all necessary Tax  Returns and
other documentation  with respect  to all  such transfer, documentary,  sales,
use, stamp, and other Taxes and fees, and, if required by applicable law,  NMS
will, and will  cause its affiliates to, join in the execution of any such Tax
Returns and other documentation.

or proceeding arising out of or relating to this Agreement in any other court.
Each  of  the  Parties  waives  any  defense  of  inconvenient  forum  to  the
maintenance  of  any action  or  proceeding so  brought  and waives  any bond,

      (q)   Arbitration.  Subject  to Section 9(n) all controversies or claims
arising  among  the  Parties  (or their  respective  successors  or  permitted
assigns) hereunder which are not resolved within thirty (30) days after either
party  notifies the  other in writing  of the  controversy or  claim, shall be
submitted  for  arbitration  on demand  of  either  party.   Such  arbitration
proceedings  will  be  conducted  in  Boston,  Massachusetts,  and  except  as
otherwise provided in this Agreement, will be conducted in accordance with the
then-current  Commercial   Arbitration  Rules  of   the  American  Arbitration
Association.   There  shall be  three arbitrators.    Each party  hereto shall
appoint one  arbitrator and the  two so appointed shall  appoint a third.   If
either party shall  refuse to appoint an arbitrator within  fourteen (14) days
of demand by the other, the arbitration shall proceed without said arbitrator.
The  arbitrators will have  the right  to award  or include  in the  award any
relief which they deem proper in the circumstances, including, but not limited
to,  money damages, interest on unpaid amounts, specific performance and other
injunctive  relief, and  reimbursement of  arbitration costs.   The  award and
decision of a majority of the  arbitrators will be conclusive and binding, and
judgment on the award may  be entered in any court of  competent jurisdiction.
Each  party hereto,  for itself  and its  respective successors  and permitted
assigns, acknowledges that any arbitration award may be enforced in a court of
competent  jurisdiction  and  waives any  right  to  contest  the validity  or
enforceability of such award.

                           STOCK PURCHASE AGREEMENT

      Agreement  entered  into as  of  June 14,  1996,  by  and among  Natural
MicroSystems Corporation,  a Delaware corporation ("NMS"),  PSR Systems, Inc.,
an  Illinois corporation ("PSR"), and the Stockholders of PSR signatory hereto
(collectively,  the  "Stockholders")  who in  the  aggregate  own  all of  the
outstanding capital  stock of PSR.   NMS and the Stockholders  are referred to
collectively herein as the "Parties."   PSR joins in this Agreement solely for
the purpose of its agreement set forth in Section 2(f).

      This Agreement  contemplates a transaction  in which  NMS will  purchase
from  the Stockholders,  and the  Stockholders will  sell to  NMS, all  of the
outstanding capital stock  of PSR in return for cash.  It is intended that the
transaction shall be recorded for accounting purposes as a purchase.

      Now, therefore, in consideration of the premises and the mutual promises
herein made,  and in  consideration of  the  representations, warranties,  and
covenants herein contained, the Parties agree as follows.

      1.    Definitions.  Certain capitalized terms are used in this Agreement
as specifically defined in Appendix 1 hereto.

      2.    Purchase and Sale of PSR Shares.

      (a)   Basic Transaction.  On and subject to the terms and  conditions of
this Agreement, NMS agrees to purchase from each of the Stockholders, and each
of the Stockholders agrees  to sell to NMS, all  of his or her PSR  Shares for
the consideration specified below in this Section 2.

      (b)   Purchase  Price.  NMS agrees to pay to the Stockholders, allocated
among  the  Stockholders in  proportion to  their  respective holdings  of PSR
Shares as  set forth in  Section 4(b) of  the Disclosure  Schedule (as may  be
modified  from time to  time in the  manner set forth  therein), the following
amounts:

            (i)   $3,550,000, which  shall be paid  by certified check  at the
      Closing; and

            (ii)  Such   amounts  (to  be  paid  by  certified  check)  to  be
      determined and  by  such  dates as  provided  in  Exhibit 2(b)(ii)  (the
      "Contingent  Amounts") provided  that  the Contingent  Amounts, if  any,
      allocable to the  Major Stockholders shall be paid  to the Escrow Agents
      to be held pursuant  to the terms of  the Escrow Agreement if  NMS shall
      have made, and there is outstanding, a written claim for indemnification
      pursuant to Section 7 below.

      (c)   The  Closing.  Simultaneously with the  delivery of this Agreement
on the  date hereof (the "Closing Date"), (i) the Stockholders will deliver to

5(a) below, and (ii) NMS  will deliver to the  Stockholders  the consideration

referred to  in Section  5(b)  below.   The Closing  shall take  place at  the
offices of Choate, Hall &  Stewart, 53 State Street,  Exchange  Place, Boston,
Massachusetts.

      (d)   Escrow Agents.  The Escrow Agents  shall be Levun, Goodman & Cohen

Goodman  & Cohen or any successor declines or  is unable to serve, it shall be
succeeded by  such person or entity,  reasonably acceptable to NMS,  as may be
designated by the Major Stockholders.  In the event Choate, Hall &  Stewart or
any successor declines or  is unable to serve,  it shall be succeeded by  such
person or entity,  reasonably acceptable to the Major Stockholders,  as may be
designated by NMS.  All payments made  to the Escrow Agents shall be held  and
distributed  in  accordance with  an agreement  substantially  in the  form of
Exhibit 2(d) hereto (the "Escrow Agreement").

and all successor or other agreements relating thereto) by and among them (and
previously  by John Schoeph) dated as of   July 31, 1980 shall be, without any
further action on the part  of any of them, terminated upon  the occurrence of

            (b)   Noncontravention.  Neither the execution and the delivery of

Stockholders  jointly  and severally  represent and  warrant  to NMS  that the
statements concerning PSR contained in this Section 4 are correct and complete
in all  material respects as  of the execution  of this Agreement on  the date
hereof, except as set forth in the disclosure schedule delivered  by the Major
Stockholders to NMS  on the date hereof  and attached hereto as  Annex II (the
"Disclosure  Schedule").  Nothing in  the Disclosure Schedule  shall be deemed
adequate to disclose an exception to a representation or warranty made herein,
however,  unless  the  Disclosure   Schedule  identifies  the  exception  with
reasonable  particularity  and  describes  the relevant  facts  in  reasonable
detail.  Without  limiting the generality of  the foregoing, the mere  listing
(or inclusion  of a copy)  of a  document or  other item shall  not be  deemed
adequate to disclose an exception to a representation or warranty made  herein
(unless the representation  or warranty has  to do with  the existence of  the
document  or  other item  itself).   The  Disclosure Schedule  is  arranged in
paragraphs corresponding to the lettered  and numbered paragraphs contained in
this Section 4.

      (a)   Organization,  Qualification,  and  Corporate  Power.   PSR  is  a
corporation duly organized, validly  existing, and in good standing  under the

laws  of Illinois and  is duly  qualified to conduct  business and  is in good
standing  under  the laws  of each  jurisdiction  where such  qualification is

Inc.   PSR has full corporate  power and authority and  all licenses, permits,
and authorizations necessary to carry on the businesses in which it is engaged
and in which it presently proposes to engage and to own and use the properties
owned and  used by it.   Section  4(a) of  the Disclosure  Schedule lists  the
directors and officers of PSR.  The Stockholders have delivered to NMS correct

(i) violate any constitution, statute, regulation, rule, injunction, judgment,
order,  decree,  ruling,  charge,  or  other  restriction of  any  government,

      All such  Tax Returns were  correct and complete  in all respects.   All

      within which to file any Tax Return.  No claim has ever been made  by an
      authority in  a jurisdiction where PSR does not file Tax Returns that it
      is  or may be  subject to taxation  by that jurisdiction.   There are no

                                             7

           (ii)   PSR  has withheld and paid  all Taxes required  to have been
      withheld  and paid  in  connection with  amounts  paid or  owing  to any
      employee, independent contractor, creditor,  stockholder, or other third
      party.

           (iii)  No   Stockholder  or   director  or  officer   (or  employee
      responsible for Tax matters) of PSR expects any authority to assess  any
      additional Taxes for any period  for which Tax Returns have  been filed.
      There is no dispute or claim  concerning any Tax Liability of PSR either

      of the  Stockholders  and  the directors  and  officers  (and  employees
      responsible  for Tax matters) of  PSR has Knowledge  based upon personal
      contact with  any  agent  of  such  authority.    Section  4(k)  of  the

      Tax Returns  filed with respect to  PSR for taxable periods  ended on or
      after  December 31, 1990,  indicates those  Tax Returns  that have  been
      audited,  and indicates those Tax Returns that currently are the subject

      under  certain circumstances could obligate it to make any payments that
      will not  be deductible under  Code Section  280G.  PSR  has not been  a
      United States real  property holding corporation  within the meaning  of
      Code Section  897(c)(2) during the  applicable period specified  in Code
      Section 897(c)(1)(A)(ii).  PSR  has disclosed on its federal  income Tax
      Returns   all  positions  taken  therein  that  could  give  rise  to  a
      substantial  understatement of federal income Tax  within the meaning of
      Code Section 6662. PSR  is not a party to any Tax  allocation or sharing
      agreement.  PSR (A) has not been  a member of an Affiliated Group filing

      transferee or successor, by contract, or otherwise.

           (vi)   Intentionally Omitted.

           (vii)  The unpaid Taxes of PSR  (A) did not, as of the  Most Recent
      Fiscal Month End,  exceed the reserve for Tax Liability (rather than any

                                             8





                                                                               


      reserve  for deferred  Taxes established  to reflect  timing differences
      between book and  Tax income) set forth  on the face of  the Most Recent
      Balance Sheet (rather  than in any notes thereto) and  (B) do not exceed
      that reserve as  adjusted for the  passage of time  through the  Closing

      its Tax Returns.

           have  been met  with  respect to  each  such Employee  Benefit Plan

           to  the terms  of an  Employee Benefit  Plan  which is  an Employee

           to   each  such  Employee  Pension  Benefit   Plan  or  accrued  in

           years,  a  favorable   unrevoked  determination  letter   from  the
           Internal Revenue  Service which determination  letter may still  be
           relied upon as to such  tax qualified status, and  no circumstances
           have  occurred that would adversely affect the tax qualified status
           of any such Employee Pension Benefit Plan.

           Controlled  Group  Member  has  incurred  any  accumulated  funding

           of the  plan  documents  and summary  plan  descriptions, the  most

legal  proceeding, interrogatory,  subpoena,  civil  investigative demand,  or
similar process)  to disclose  any Confidential Information,  that Stockholder
will notify NMS promptly of the request or requirement so that NMS may seek an

reasonable  request  of NMS,  an order  or  other assurance  that confidential
treatment will be  accorded to  such portion of  the Confidential  Information
required  to be disclosed  as NMS shall  designate.  The  foregoing provisions
shall not apply to  any Confidential Information which is  generally available
to the public immediately prior to the time of disclosure.

and warranties made by each of  the Parties in this Agreement shall  be deemed
to have been  relied upon by  the other Parties  hereto and shall  survive the
Closing,  provided  that in  no  event shall  any  Party be  entitled  to seek

such remedy shall  not be so  limited) pursuant to this  Section 7 unless  the
Party  seeking indemnification has made  a written claim  therefor pursuant to

           (i)    In the event  any of  the Stockholders breaches  (or in  the
      event any third party alleges facts that, if true, would mean any of the
      Stockholders has breached) any of their representations, warranties, and
      covenants  contained herein, provided that NMS makes a written claim for
      indemnification  against  any of  the  Stockholders  by  notice  to  the
      Representatives pursuant to Section 9(h) below prior to January 1, 1998,
      then each  of the Major  Stockholders agrees  to indemnify NMS  from and
      against  the entirety of any Adverse Consequences NMS may suffer through
      and  after  the date  of the  claim  for indemnification  (including any
      Adverse Consequences  NMS may suffer after  December 31, 1997) resulting
      from, arising out  of, relating to, in the  nature of, or caused  by the
      breach (or the alleged  breach); provided that, in no event shall either
      of  the Major  Stockholders  be liable  hereunder  for an  amount  which
      exceeds  the  total   aggregate  consideration  paid   to  all  of   the
      Stockholders hereunder for the sale of all of the PSR Shares to NMS.

           (ii)   In the event NMS breaches (or  in the event any third  party
      alleges facts  that, if true,  would mean NMS  has breached) any  of its
      representations,  warranties, and  covenants contained  herein, provided
      that Representatives  makes a written claim  for indemnification against
      NMS pursuant to Section  9(h) below prior  to January 1, 1998, then  NMS

      Adverse  Consequences  the  Stockholders may  suffer  after December 31,
      1997) resulting from, arising out of, relating to, in the  nature of, or
      caused by the breach (or the alleged breach).

      (c)  Matters Involving Third Parties.

           (i)    If  any third party shall notify any Party (the "Indemnified
      Party")  with respect to  any matter (a  "Third Party Claim")  which may
      give rise  to a claim for  indemnification against any  other Party (the
      "Indemnifying Party") under this Section  7, then the Indemnified  Party
      shall  promptly  notify  each  Indemnifying Party  thereof  in  writing;
      provided, however, that no delay on the part of the Indemnified Party in
      notifying any  Indemnifying Party  shall relieve the  Indemnifying Party
      from any obligation hereunder unless (and then solely to the extent) the
      Indemnifying Party thereby is prejudiced.

           (ii)   Any Indemnifying  Party will  have the  right to defend  the
      Indemnified  Party against  the Third  Party Claim  with counsel  of its
      choice reasonably satisfactory to  the Indemnified Party so long  as (A)
      the Indemnifying Party notifies the Indemnified Party in writing  within
      15 days after the Indemnified Party  has given notice of the Third Party
      Claim that the  Indemnifying Party will indemnify  the Indemnified Party
      from  and  against  the   entirety  of  any  Adverse   Consequences  the
      Indemnified Party  may suffer resulting  from, arising out  of, relating
      to,  in the  nature of,  or caused  by the  Third Party  Claim, (B)  the
      Indemnifying  Party   provides  the  Indemnified  Party   with  evidence

                                            24





                                                                               


      reasonably  acceptable to  the Indemnified  Party that  the Indemnifying
      Party  will have  the financial  resources to  defend against  the Third
      Party Claim  and fulfill its indemnification  obligations hereunder, (C)
      the Third Party Claim involves  only money damages and does not  seek an
      injunction or other equitable  relief, (D) settlement of, or  an adverse
      judgment with  respect to,  the Third  Party Claim is  not, in  the good
      faith  judgment  of  the  Indemnified  Party,  likely   to  establish  a
      precedential  custom or  practice materially  adverse to  the continuing
      business interests  of the Indemnified  Party, and (E)  the Indemnifying
      Party  conducts  the  defense of  the  Third  Party  Claim actively  and
      diligently.

           (iii)  So  long as the Indemnifying Party is conducting the defense
      of the Third Party Claim in accordance with  Section 7(c)(ii) above, (A)
      the  Indemnified Party may retain  separate co-counsel at  its sole cost
      and expense and participate in the defense of the Third Party Claim, (B)
      the  Indemnified Party will not consent to  the entry of any judgment or
      enter into any settlement with respect  to the Third Party Claim without
      the prior written consent of the Indemnifying  Party (not to be withheld
      unreasonably),  and (C) the Indemnifying  Party will not  consent to the
      entry of any  judgment or enter into any settlement  with respect to the
      Third Party Claim without  the prior written consent of  the Indemnified
      Party (not to be withheld unreasonably).

           (iv)   In the event any of the conditions in Section 7(c)(ii) above
      is or becomes unsatisfied, however, (A) the Indemnified Party may defend
      against, and  consent to  the entry  of any judgment  or enter  into any
      settlement with  respect to,  the Third  Party Claim  in  any manner  it
      reasonably  may  deem appropriate  (and the  Indemnified Party  need not
      consult  with, or  obtain any  consent from,  any Indemnifying  Party in
      connection therewith),  (B) the Indemnifying Parties  will reimburse the
      Indemnified  Party promptly and periodically  for the costs of defending
      against the Third Party Claim  (including reasonable attorneys' fees and
      expenses), and (C) the Indemnifying Parties will  remain responsible for
      any  Adverse Consequences  the  Indemnified Party  may suffer  resulting
      from, arising out  of, relating to, in  the nature of, or  caused by the
      Third Party Claim to the fullest extent provided in this Section 7.

      (d)  Other Indemnification  Provisions.   The foregoing  indemnification
provisions  are in  addition  to, and  not in  derogation  of, any  statutory,
equitable,  or  common   law  remedy  any  Party   may  have  for  breach   of
representation, warranty, or covenant.  Each of the Stockholders hereby agrees
that he will not make any  claim for indemnification against PSR by reason  of
the fact that  he was  a director,  officer, employee,  or agent  of any  such
entity or was serving at the request of any such entity as a partner, trustee,
director, officer, employee, or agent of another entity (whether such claim is
for judgments, damages, penalties,  fines, costs, amounts paid  in settlement,
losses, expenses,  or otherwise  and  whether such  claim is  pursuant to  any
statute, charter document, bylaw, agreement, or otherwise) with respect to any
action, suit, proceeding, complaint,  claim, or demand brought by  NMS against

                                            25





                                                                              


such Stockholder (whether such action,  suit, proceeding, complaint, claim, or
demand is pursuant to this Agreement, applicable law, or otherwise).

      8.   Tax Matters.  

      (a)  Cooperation on Tax Matters.

           (i)    NMS and the  Stockholders shall cooperate  fully, as and  to
      the extent reasonably requested  by the other party, in  connection with
      the  filing of Tax Returns for PSR for all periods after or prior to the
      Closing  Date which  are filed  after the  Closing  Date and  any audit,
      litigation  or other proceeding with respect to Taxes.  Such cooperation
      shall include the  retention and  (upon the other  party's request)  the
      provision of records  and information which  are reasonably relevant  to
      any  such audit,  litigation or  other proceeding  and making  employees
      available  on   a  mutually  convenient  basis   to  provide  additional
      information  and explanation  of any material  provided hereunder.   The
      Stockholders agree (A)  to retain all books and records  with respect to
      Tax  matters pertinent to PSR  relating to any  taxable period beginning
      before  the  Closing  Date  until  the  expiration  of  the  statute  of
      limitations (and, to the extent notified by NMS, any extensions thereof)
      of the  respective taxable periods, and to abide by all record retention
      agreements  entered into with any taxing authority,  and (B) to give the
      other party reasonable written  notice prior to transferring, destroying
      or discarding  any such books and  records and, if NMS  so requests, the
      Stockholders  shall allow  NMS  to take  possession  of such  books  and
      records.

           (ii)   NMS  and Stockholders  further agree,  upon request,  to use
      their best efforts to obtain any certificate  or other document from any
      governmental  authority or  any  other Person  as  may be  necessary  to
      mitigate,  reduce or eliminate any Tax that could be imposed (including,
      but  not  limited to,  with  respect  to the  transactions  contemplated
      hereby).

           (iii)  NMS and Stockholders further agree, upon request, to provide
      the other  party with all information that  either party may be required
      to  report  pursuant  to Section  6043  of  the  Code and  all  Treasury
      Department Regulations promulgated thereunder.

      (b)  Tax  Sharing Agreements.   All  tax sharing  agreements  or similar
agreements with  respect to  or involving  PSR shall be  terminated as  of the
Closing Date and,  after the Closing Date,  PSR shall not be bound  thereby or
have any liability thereunder.

      (c)  Certain Taxes.   All transfer,  documentary, sales, use, stamp  and
other such Taxes and fees  (including any penalties and interest) incurred  in
connection with this  Agreement shall be  paid by Stockholders  when due,  and
Stockholders  will, at their own  expense, file all  necessary Tax Returns and
other documentation  with respect  to all  such transfer, documentary,  sales,

                                            26





                                                                               


use,  stamp, and other Taxes and fees, and, if required by applicable law, NMS
will, and will cause its affiliates to, join in the execution  of any such Tax
Returns and other documentation.

      9.   Miscellaneous.

      (a)  Nature of Certain  Obligations.   The representations,  warranties,
and covenants in this Agreement are joint and several obligations.   Joint and
several means that  each of the Major Stockholders will  be responsible to the
extent  provided  in  Section  7  above  for  the  entirety  of  any   Adverse
Consequences NMS may suffer as a result of any breach thereof.

      (b)  Press Releases  and Public Announcements.   The Stockholders  shall
not issue  any press release or  make any public announcement  relating to the

successors and permitted assigns.

the subject matter hereof.

      (e)  Succession and  Assignment.  This Agreement  shall be  binding upon
and inure  to the benefit  of the  Parties named herein  and their  respective
successors and permitted  assigns.  No Party may assign  either this Agreement
or any of  his or her rights, interests, or  obligations hereunder without the
prior  written approval of NMS  and the Stockholders;  provided, however, that
(i) NMS may (A) assign any or all of its rights and interests hereunder to one
or more of its Affiliates and  (B) designate one or more of its  Affiliates to
perform  its  obligations  hereunder  (in  any  or  all  of  which  cases  NMS
nonetheless  shall  remain  responsible for  the  performance  of  all of  its
obligations hereunder) and  (ii) each  of the Stockholders  may assign,  after
written  notice  to  NMS,  the  related  portion  of  his  or  her  rights  to
consideration hereunder so  long as  such Stockholder remains  liable for  the
full performance of all of his or her obligations hereunder.

      (f)  Counterparts.   This  Agreement may  be  executed  in one  or  more
counterparts,  each of  which shall  be deemed  an original  but all  of which
together will constitute one and the same instrument.

      (g)  Headings.   The  section headings contained  in this  Agreement are
inserted for  convenience only and shall not affect  in any way the meaning or
interpretation of this Agreement.

If to the Escrow Agents:      At their respective addresses set forth above

Any Party may send any notice, request, demand, claim, or  other communication
hereunder to the  intended recipient at the address set  forth above using any
other  means  (including  personal  delivery,  expedited  courier,   messenger
service,  telecopy, telex,  ordinary mail,  or electronic  mail), but  no such
notice, request, demand, claim, or other communication shall be deemed to have
been  duly given  unless and  until it  actually is  received by  the intended
recipient.   Any  Party may  change  the address  to which  notices, requests,
demands, claims, and  other communications  hereunder are to  be delivered  by
giving the other Parties notice in the manner herein set forth.

      (i)  Governing Law.   This Agreement shall  be governed  by and construed
in  accordance with  the domestic  laws of  The Commonwealth  of Massachusetts
without  giving effect  to any  choice or  conflict of  law provision  or rule
(whether  of The Commonwealth of Massachusetts or any other jurisdiction) that
would  cause the application  of the laws  of any jurisdiction  other than The
Commonwealth of Massachusetts.

      (j)  Amendments  and Waivers.   No  amendment  of  any provision  of this
Agreement shall be valid unless the same shall be in writing and signed by NMS
and   the  Stockholders.     No   waiver  by   any  Party   of   any  default,
misrepresentation,  or  breach  of  warranty or  covenant  hereunder,  whether
intentional  or not,  shall be  deemed to  extend to  any prior  or subsequent
default, misrepresentation,  or breach of  warranty or  covenant hereunder  or
affect in any way any rights arising by virtue of any prior or subsequent such
occurrence.

                                            28





                                                                               




      (k)  Severability.   Any  term or  provision  of  this Agreement  that is
invalid or unenforceable in any situation in any jurisdiction shall not affect
the validity or enforceability of the remaining terms and provisions hereof or
the validity or enforceability of the offending term or provision in any other
situation or in any other jurisdiction.

      (l)  Expenses.  Each  of the Parties will bear his, her or  its own costs
and expenses (including legal  fees and expenses) incurred in  connection with
this  Agreement and  the transactions  contemplated hereby.   The Stockholders
agree  that,  other than  the expense  of financial  audits  of the  books and
records of PSR, PSR has  not borne or will bear any of the Stockholders' costs
and expenses (including any  of their legal fees  and expenses) in  connection
with this Agreement or any of the transactions contemplated hereby. 

      (m)  Construction.    The  Parties  have  participated  jointly  in   the
negotiation and  drafting of this  Agreement.   In the event  an ambiguity  or
question of intent or interpretation arises, this Agreement shall be construed
as if drafted  jointly by the  Parties and no presumption  or burden of  proof
shall arise favoring or disfavoring  any Party by virtue of the  authorship of
any of the provisions of this Agreement.  Any reference to any federal, state,
local, or foreign  statute or law shall be  deemed also to refer to  all rules
and regulations promulgated thereunder, unless the context requires otherwise.
The word "including"  shall mean  including without limitation.   The  Parties
intend that each representation, warranty, and covenant contained herein shall
have  independent significance.  If any Party has breached any representation,
warranty, or covenant  contained herein in  any respect, the  fact that  there
exists another  representation, warranty,  or covenant  relating  to the  same
subject  matter (regardless of the  relative levels of  specificity) which the
Party has  not breached shall not detract  from or mitigate the  fact that the
Party is in breach of the first representation, warranty, or covenant.

      (n)  Incorporation of  Exhibits, Annexes, and  Schedules.  The  Exhibits,
Annexes, and Schedules identified in this Agreement are incorporated herein by
reference and made a part hereof.

      (o)  Specific Performance.  Each of the  Parties acknowledges and  agrees
that the other  Parties would be damaged irreparably  in the event any  of the
provisions  of this  Agreement  are not  performed  in accordance  with  their
specific terms or  otherwise are breached.   Accordingly, each of  the Parties
agrees  that  the  other  Parties  shall  be  entitled  to  an  injunction  or
injunctions to prevent  breaches of the  provisions of  this Agreement and  to
enforce specifically this Agreement and the terms and provisions hereof in any
action  instituted in  any court  of the  United States  or any  state thereof
having jurisdiction over the Parties and the matter (subject to the provisions
set forth  in Section 9(p)  below), in addition  to any other  remedy to which
they may be entitled, at law or in equity.

      (p)  Submission to  Jurisdiction.   Each of  the Parties  submits to  the
jurisdiction of any state  or federal court sitting in  Boston, Massachusetts,
in any  action or proceeding arising out of or  relating to this Agreement and

                                            29





                                                                                


agrees that all claims in respect of the action or proceeding may be heard and
determined in any such court.  Each Party also agrees not  to bring any action
or proceeding arising out of or relating to this Agreement in any other court.
Each  of  the  Parties  waives  any  defense  of  inconvenient  forum  to  the
maintenance  of any  action  or proceeding  so  brought and  waives  any bond,
surety,  or other  security that  might be  required of  any other  Party with
respect thereto.  

      (q)  Arbitration.  Subject to Section 9(o),  all controversies or  claims
arising  among  the  Parties  (or their  respective  successors  or  permitted
assigns) hereunder which are not resolved within thirty (30) days after either
party notifies  the other  in writing  of the controversy  or claim,  shall be
submitted  for  arbitration  on demand  of  either  party.   Such  arbitration
proceedings  will  be  conducted  in  Boston,  Massachusetts,  and  except  as
otherwise provided in this Agreement, will be conducted in accordance with the
then-current  Commercial  Arbitration   Rules  of  the   American  Arbitration
Association.   There shall  be three  arbitrators.   Each  party hereto  shall
appoint one arbitrator  and the two  so appointed shall appoint  a third.   If
either party shall refuse  to appoint an arbitrator within fourteen  (14) days
of demand by the other, the arbitration shall proceed without said arbitrator.
The arbitrators  will have the  right to  award or  include in  the award  any
relief which they deem proper in the circumstances, including, but not limited
to,  money damages, interest on unpaid amounts, specific performance and other
injunctive  relief, and  reimbursement of  arbitration costs.   The  award and
decision of  a majority of the arbitrators will be conclusive and binding, and
judgment  on the award may be entered  in any court of competent jurisdiction.
Each  party hereto,  for itself  and its  respective successors  and permitted
assigns, acknowledges that any arbitration award may be enforced in a court of
competent  jurisdiction  and  waives any  right  to  contest  the validity  or
enforceability of such award.
