                          AGREEMENT AND PLAN OF MERGER


         AGREEMENT AND PLAN OF MERGER, dated as of the 10th day of July 1996, by
and  among  CENTENNIAL   ACQUISITION   CORPORATION   ("CAC"),   a  Massachusetts
corporation;  CENTENNIAL  TECHNOLOGIES,  INC.,  a Delaware  corporation  and the
parent of CAC ("Centennial"); and DESIGN CIRCUITS, INC. ("DCI"), a Massachusetts
corporation  (CAC and DCI  being  hereinafter  collectively  referred  to as the
"Constituent Corporations").

         WHEREAS,  the  Board  of  Directors  of  Centennial,  CAC and DCI  have
approved the merger of CAC with and into DCI (the  "Merger")  upon the terms and
subject to the conditions set forth herein; and

         NOW,   THEREFORE,   intending  to  be  legally  bound  hereby,  and  in
consideration  of the  mutual  covenants  herein  contained  and other  good and
valuable  consideration,   the  receipt  and  sufficiency  of  which  is  hereby
acknowledged, the parties hereto agree as follows:

         1.       THE MERGER

                  (a) On the Effective  Date (as defined in Section  1(b)),  CAC
shall be merged with and into DCI in accordance  with the applicable  provisions
of the Business  Corporation Law of the Commonwealth of  Massachusetts,  and the
separate  existence  of CAC  shall  thereupon  cease,  and DCI as the  surviving
corporation  in the Merger (the  "Surviving  Corporation"),  shall  continue its
corporate  existence under the laws of the Commonwealth of  Massachusetts  under
the name of Design  Circuits,  Inc.  Upon the  consummation  of the Merger,  the
franchises  and  all  the  property,   real,   personal  and  mixed,   including
subscriptions  to shares,  causes of action and every other asset of each of the
Constituent  Corporations,  shall  vest  in the  Surviving  Corporation  without
further act or deed.  The Surviving  Corporation  shall assume and be liable for
all the liabilities  and obligations of each of the Constituent  Corporations in
accordance   with  the  Business   Corporation   Law  of  the   Commonwealth  of
Massachusetts.

         (b)  Subject  to the terms and  conditions  herein,  on the date of the
Closing  described  in Section 14 herein  there shall be duly  delivered  to the
Secretary of State of the Commonwealth of Massachusetts,  in accordance with the
Business  Corporation  Law of the  Commonwealth  of  Massachusetts  Articles  of
Merger, duly executed by the Constituent  Corporations.  The Merger shall become
effective upon the date specified (the "Effective  Date") in an escrow agreement
(the "Escrow  Agreement") of even date herewith.  The closing (the "Closing") of
the  transactions  contemplated  by this Agreement  shall take place on July 10,
1996 at the offices of O'Connor,  Broude & Aronson in Waltham,  Massachusetts or
such other place as the parties may agree (the "Closing Date"). All transactions
shall be deemed to have  occurred  simultaneously,  and none  shall be deemed to
have occurred until all other transactions shall have been taken.

         (c) The Merger is  intended  to  qualify  as a tax-free  reorganization
under Sections  368(a)(1)(A)  and  368(a)(2)(E) of the Internal  Revenue Code of
1986.






         2.       SURVIVING CORPORATION

         (a) The name of the  Surviving  Corporation  shall  initially be Design
Circuits, Inc.

         (b) The  Articles of  Organization  of DCI (the "DCI  Articles")  as in
effect on the  Effective  Date  shall be the  Articles  of  Organization  of the
Surviving  Corporation,  and the purposes as set forth in DCI Articles  shall be
the purposes of the Surviving Corporation.

         (c) The authorized capital stock of the Surviving  Corporation shall be
200,000  shares  of common  stock,  par value  $.01 per share  (the "DCI  Common
Stock").

         (d) The Bylaws of CAC as in effect on the  Effective  Date shall be the
Bylaws of the Surviving Corporation.

         (e) The  directors  and officers of the  Surviving  Corporation  on the
Effective  Date  shall be as set  forth in  Schedule  2(e)  hereto,  to serve in
accordance with the Bylaws of the Surviving Corporation.

         3.       CONVERSION OF SHARES

         (a) As of the  Effective  Date, by virtue of the Merger and without any
action on the part of the holders therein:

                  (i) All  shares of DCI Common  Stock  which are held by DCI as
treasury  shares,  and  DCI  Common  Stock  owned  by CAC or any  other  company
controlling, controlled by or under common control with CAC shall be cancelled.

                  (ii) The  outstanding  shares of capital stock of DCI shall be
converted  into an aliquot  share (the  "Exchange  Amount") of the Merger  Price
(identified  below) in  accordance  with the  provisions  of DCI's  Articles  of
Organization,  as  amended.  The  Exchange  Amount  each  shareholder  of DCI (a
"Shareholder," and, collectively,  the "Shareholders") will receive is set forth
in Schedule 3(a)(ii).

                  (iii) Each outstanding  share of common stock,  $.01 par value
per share of CAC shall be converted into one share of DCI Common Stock.

         (b) The Merger Price shall be $5,622,077 in cash (the "Cash  Portion"),
plus 100,000 shares of common stock,  $.01 par value per share, (the "Centennial
Common Stock") of Centennial  (the "Stock  Portion").  The Cash Portion shall be
paid by certified  or bank check or by wire  transfer in  immediately  available
funds, subject to the provisions of this Agreement.

         (c) The Cash Portion determined pursuant to Section 3(b) and (c) herein
shall be reduced in accordance with the provisions of Section 5 herein.

                                       -2-




         (d) The number of shares of  Centennial  Common  Stock  included in the
Stock  Portion will be increased if the weighted  average  closing  price of the
Centennial  Common  Stock during the ten trading days before the Closing Date as
reported by the American Stock  Exchange is less than $21.50 per share.  In this
event,  the number of shares of  Centennial  Common Stock  included in the Stock
Portion will be increased to equal  $2,400,000  divided by the weighted  average
closing price of the Centennial  Common Stock during the ten trading days before
the Closing Date.

         (e)      The Merger Price shall be paid as follows:

                  (i)  $5,372,077  and a letter of  instruction  to the transfer
agent (the "Instruction  Letter") of Centennial  instructing such agent to issue
100,000  shares of  Centennial  Common Stock to the  Shareholders  in amounts as
provided  by DCI to  Centennial  shall be  delivered  on the Closing  Date.  The
Instruction  Letter shall  provide for  overnight  delivery of the Shares to the
Shareholder Representative.

                  (ii)  $250,000  the ("Escrow  Amount")  shall be paid 120 days
following the Closing Date, subject to the provisions of Section 5 herein.

         (f) On the  Effective  Date,  each holder of record of capital stock of
DCI shall  surrender his certificate or  certificates,  which shall be converted
automatically  into the right to receive an aliquot  share of the Merger  Price.
All  shares  of  capital  stock  of DCI  outstanding  immediately  prior  to the
Effective Date shall be cancelled on the Effective Date  irrespective of whether
such shares were  surrendered  as provided in this Section  3(f) and  thereafter
shall represent only the right to receive the aliquot share of the Merger Price,
without interest.

         4.       SHARE REPURCHASE

         (a) On terms and subject to the conditions  hereof,  Centennial  hereby
irrevocably   grants  to  the  Shareholders,   acting  through  the  Shareholder
Representative,  the  right  (the  "Put  Right")  to  sell  to  Centennial,  and
Centennial  (upon exercise of such Put Right) hereby  unconditionally  agrees to
purchase from Tendering  Shareholders  (as defined  herein),  on the Put Closing
Date  hereinafter  referred  to, up to a maximum  of  100,000  shares  (the "Put
Securities") as may be adjusted  pursuant to this Section 4(a) of the Centennial
Common Stock to be issued in  connection  with the Merger at the price of $20.00
per  share  (the  "Purchase  Price").  The  number  of Put  Securities  shall be
appropriately  adjusted to take into account any stock splits,  stock dividends,
recapitalization,  merger,  consolidation or similar events taking place between
the Effective Date and the Put Closing Date. The  determination  of the Board of
Directors of  Centennial  as to the  appropriate  adjustment  to be made in such
circumstances  shall be conclusive,  absent manifest error.  Notwithstanding any
contrary  provision  hereof,  the Put Right shall terminate and be of no further
force or effect on a date (the  "Termination  Date") which is the earlier of (i)
the date which is six months after the date on which the registration  statement
referred to in Section 21 hereof becomes effective, or (ii) the date (after such
effective  date) on which the weighted  average  closing price of the Centennial
Common Stock as reported on The American Stock Exchange has exceeded  $24.00 per
share for at least ten

                                       -3-




consecutive  trading  days  during  which the trading  volume  averages at least
50,000 shares per day (i.e., at least 500,000 shares for such ten-day period).

         (b) The  Shareholder  Representative,  when so  directed  in writing by
Shareholders  whom at the time  continue  to own a  majority  of the  shares  of
Centennial Common Stock issued in connection with the Merger, shall exercise the
Put Right once at any time between the Effective Date and the  Termination  Date
by providing  written notice to Centennial,  stating that the Put Right is being
exercised and designating a date reasonably acceptable to Centennial for closing
the purchase and sale which is not less than twenty (20) and not more than forty
(40) days after the date of such notice (the "Put Closing  Date").  Concurrently
with the giving of the foregoing notice,  the Shareholder  Representative  shall
give each  Shareholder  written notice that the Put Right is being exercised and
giving such Shareholder an opportunity  within ten (10) days thereto to elect to
participate  or not  participate  in the  Put  Right  and to  designate  its Put
Securities,  if any. At least seven (7) days prior to the Put Closing Date,  the
Shareholder   Representative   shall  give  Centennial  written  notice  of  the
Shareholders  (the "Tendering  Shareholders")  (and number of Put Securities for
each) that have elected to participate in the Put Right on the Put Closing Date.
The sale and purchase of the Put Securities  shall take place on the Put Closing
Date or at such other date as the parties may mutually  agree, at the offices of
O'Connor,  Broude & Aronson in Waltham,  Massachusetts or at such other location
as the parties may mutually agree.  At the Put Closing,  Centennial will pay the
Purchase Price to the Tendering  Shareholders,  acting  through the  Shareholder
Representative,  by wire transfer of immediately  available  federal funds;  and
against  payment of such funds the Tendering  Shareholders,  acting  through the
Shareholder  Representative,  will deliver  certificates  for the Put Securities
with endorsements or stock powers to the name of Centennial.

         5.       HOLDBACK PROVISIONS

         (a) Centennial  shall retain the Escrow Amount for a period of 120 days
following  the Closing Date (the  "Escrow  Period").  On the first  business day
after  the  Escrow  Period,  Centennial  shall  pay  the  Escrow  Amount  to the
Shareholder Representative, as defined in Section 10(l), for distribution to the
Shareholders  in  accordance  with  Schedule   3(a)(ii).   Notwithstanding   the
foregoing, all or any portion of the Escrow Amount may be retained by Centennial
in the event Centennial or CAC (or,  following the Closing Date, DCI) incurs any
damages,   losses,   obligations,   liabilities,   claims,  costs  and  expenses
(collectively, "Liabilities") incident to any suit, action, investigation, claim
or  proceeding,  suffered,  sustained,  incurred  or  required  to  be  paid  by
Centennial or CAC (or, following the Closing Date, by DCI) by reason of:

                  (i) Any misrepresentation or breach of warranty made by DCI in
or pursuant to this  Agreement or any Schedule  hereto or in any  certificate or
document delivered pursuant to this Agreement; or

                  (ii) Any  failure by DCI to observe or perform  its  covenants
and  agreements  set forth herein,  which are to be performed on or prior to the
Closing Date; or

                                       -4-




                  (iii) Any claim, debt,  liability or obligation or any alleged
claim,  debt,  liability or obligation of DCI to any party,  incurred before the
Closing Date hereunder or arising from any matter or thing occurring  before the
Closing  Date  hereunder,  and which  does not  appear as a  liability  on DCI's
Balance  Sheet of May 31,  1996  (and  which  according  to  generally  accepted
accounting  principles  should have appeared on such Balance Sheet),  except for
(x)  liabilities  expressly  disclosed in this Agreement or any Schedule  hereto
(unless otherwise  indicated herein or therein) and (y) liabilities  (other than
Taxes)  incurred  between the date of this  Agreement and the Closing Date,  the
incurrence of which does not violate the provisions of this Agreement;

                  (iv) Any Taxes (as  defined  herein) of DCI,  for all  taxable
periods  up to and  including  the  Effective  Date  in  excess  of the  accrual
established  for such  liabilities  for such periods on the October 31, 1995 and
May 31, 1996 Balance Sheets, and all actions, proceedings, demands, assessments,
judgments, costs and expenses,  including reasonable attorneys' fees incident to
the foregoing;

                  (v) Any claim by any Shareholder of DCI relating to or arising
out of the Merger or this Agreement.

         (b) If  Centennial  shall in good faith  believe  that a Liability  has
arisen or exists during the Escrow  Period,  it shall give prompt written notice
to the Shareholder Representative.  Such written notice shall specify the amount
and  nature  of the  Liability,  and of any  matter  which,  in the  opinion  of
Centennial,   is  likely  to  give  rise  to  a  Liability.   The   Shareholders
Representative  shall have the right to dispute the  existence of a Liability by
providing  Centennial  written  notice  within  five (5) days of  receipt of the
notice  from  Centennial.  Upon  receipt  of the  notice  from  the  Shareholder
Representative,  Centennial  and the  Shareholder  Representative  shall in good
faith  endeavor  to  arrive  at  a  mutually  acceptable   resolution  to  their
disagreement.  If the  parties are unable to reach a  resolution  within 30 days
following the receipt of the notice from the  Shareholder  Representative,  they
shall submit their dispute to arbitration  in accordance  with the provisions of
Section 13 herein.

         (c) Any  remedies  of  Centennial  or CAC shall be  cumulative  and not
exclusive.  Specifically,  but not by way of  limitation,  the  parties  make no
attempt to limit any claims based on common law fraud or other similar remedies.

         6.       REPRESENTATIONS AND WARRANTIES OF DCI

         Except as set forth in  Schedule  6, DCI  represents  and  warrants  to
Centennial and CAC, upon which representations and warranties Centennial and CAC
rely, and which representations and warranties shall survive the Closing for 120
days  notwithstanding  any  investigation of the affairs of DCI by Centennial or
CAC, as follows:

         (a) DCI is a corporation  duly organized,  validly existing and in good
standing under the laws of the Commonwealth of Massachusetts, and has full power
and authority to own its properties and carry on its business as it is now being
conducted and as presently proposed to be conducted.

                                       -5-




DCI is not qualified,  licensed or registered to do business in any other state,
nor by the location and nature of its business and  activities and the character
of the  properties  owned by it, is it required to be so qualified,  licensed or
registered. Its Articles of Organization and all amendments thereto to date, its
Bylaws as amended to date,  and its Minutes  and Stock  Book,  all of which have
been  delivered to Centennial  for review prior to execution of this  Agreement,
are full,  complete  and correct  except as provided in Schedule  6(a)  attached
hereto.  The said Minutes  accurately  and fully reflect all meetings,  actions,
proceedings and other matters properly includable therein except as disclosed in
Schedule  6(a)  attached  hereto.  Except as  reflected  in said  Minutes and as
disclosed in Schedule 6(a) attached hereto,  there are no minutes of meetings or
consents in lieu of meetings of the Board of Directors or Shareholders of DCI.

         (b) DCI has full power and authority  (corporate  and other) to execute
and deliver this Agreement and consummate the transactions  contemplated hereby.
The  execution  and  delivery  of this  Agreement  and the  consummation  of the
transactions  contemplated  hereby have been duly and validly  authorized by the
Board of  Directors  of DCI and,  except for  obtaining  the  approval  of DCI's
Shareholders,  no other  corporate  action or proceedings on the part of DCI are
necessary to consummate the  transactions  so  contemplated.  This Agreement has
been duly and validly  executed and delivered by DCI and  constitutes  the valid
and legally binding obligation of DCI, enforceable against it in accordance with
its terms, subject only as to enforcement to general equitable principles and to
bankruptcy, insolvency,  reorganization,  moratorium, or similar laws of general
application affecting the rights and remedies of creditors.  Except as set forth
on Schedule  6(b),  the  execution  and  delivery of this  Agreement by DCI, the
consummation by DCI of the transactions  contemplated  hereby, and compliance by
DCI with the terms and  provisions  herein will not violate any provision of the
Articles of  Organization  or Bylaws of DCI in existence as of the Closing Date,
will not conflict with or result in a breach,  default, or violation of any term
of any indebtedness,  mortgage, indenture,  contract, agreement, lease, license,
permit,  judgment,  decree,  order,  or  injunction  by  which  it or any of its
properties  are or may be bound,  or of any  applicable  statute,  ordinance  or
regulation,  and will not result in the creation or  imposition of any lien upon
any of the properties of DCI.  Except for such consents as are obtained prior to
the  Closing  Date,  no  consent,  approval,  order,  or  authorization  of,  or
registration,  declaration,  or  filing  with,  any  governmental  authority  is
required in connection  with the execution and delivery of this Agreement by DCI
or the consummation by DCI of the transactions contemplated hereby.

         (c) DCI has delivered to Centennial  (i) copies of DCI's federal income
tax returns as more fully  identified on Schedule  6(c)(i)  attached  hereto and
made part herein,  for the periods set forth therein;  and (ii) certain  audited
and unaudited  financial  statements more fully identified on Schedule  6(c)(ii)
(the "Financial Statements"). The Financial Statements have been audited, except
as set forth on  Schedule  6(c)(ii),  and  certified  without  qualification  or
exception,  and include  Balance  Sheets,  Statements of Operations and Retained
Earnings (Deficit), Statements of Changes in Stockholders' Equity and Statements
of Cash Flow,  all of which have been prepared  according to generally  accepted
accounting principles, consistently applied, and collectively, together with the
Notes  thereto,  fairly present the financial  position,  and the results of the
operations  of DCI as of the dates and for the periods  indicated.  All accounts
receivable included in the May 31, 1996 Balance

Sheet (net of the reserve indicated thereon) are valid and genuine, arose out of
bona fide delivery of products or services to customers,  are not subject to any
defense,  set-off or  counterclaim,  are due and payable in the ordinary  course
within no more than (90) days  after the date of  delivery  of the  products  or
services,  are  payable  in United  States  dollars  and are not  subject to any
foreign  government  restrictions on payment.  Each of the Financial  Statements
contains  and  reflects  all  adjustments  and  accruals  required by  generally
accepted accounting principles,  except for interim statements which are subject
to normal year-end adjustments. The inventory of DCI is merchantable and fit for
its intended purpose,  is in good and marketable  condition,  and is saleable or
usable in the ordinary course of DCI's business.

         (d)  As of  May  31,  1996,  DCI  had no  liabilities,  commitments  or
obligations of any kind whatsoever  (whether  accrued,  absolute,  contingent or
otherwise,  and  whether  due or to become  due)  which  were not  reflected  or
reserved  against in its Balance  Sheet or in the Notes thereto of said date, or
which are not fully  covered by  policies  of  insurance  validly  in force,  or
disclosed herein or in a Schedule  hereto,  except for those which do not exceed
$1,000 in the aggregate and arose in the ordinary  course of DCI's  business and
are  reflected  in its books and  records.  Moreover,  except  as  described  on
Schedule  6(d)  attached  hereto,  on the date of execution  herein DCI does not
have,  nor will it on the Closing Date have,  any  liabilities,  commitments  or
obligations which were incurred after May 31, 1996, except for those which arose
in the  ordinary  course of DCI's  business  and are  reflected in its books and
records or are incurred as a result of the performance of this Agreement, or are
disclosed in any Schedule hereto.

         (e) Since May 31, 1996,  except as described on Schedules 6(d) and 6(e)
attached  hereto  and made a part  hereof,  there  has not  been  (and as of the
Closing  Date,  there  will not have  been) (i) any  change  in DCI's  business,
properties,  assets, financial condition,  prospects,  management or operations,
other than  changes in the ordinary  course of business,  none of which has been
materially adverse; (ii) any damage, destruction or loss, whether or not covered
by insurance,  materially and adversely  affecting DCI's  properties,  business,
assets or financial  position;  (iii) any  declaration  or setting  aside of any
dividend,  or any direct or indirect redemption,  purchase, or other acquisition
of any of DCI's shares of capital stock;  (iv) any increase in the  compensation
payable  or to  become  payable  by DCI to any of its  officers,  employees,  or
agents, or any bonus payment or arrangement made to or with any of them; (v) any
unresolved  labor  controversy;  (vi) any  increase in any  employee  pension or
retirement plans or other employee benefit plans; (vii) any waiver of any rights
of material value to DCI or cancellation  or compromise of any debt;  (viii) any
transfer  or grant of any rights in DCI's  patents,  trademarks,  trade names or
copyrights;  (ix)  any  material  modification,  change  or  termination  of any
existing  license,  lease,  contract  or  other  document  referred  to in  this
Agreement  or any of the  Schedules  hereto,  or  failure to renew or extend any
material contract,  except in the ordinary course of business or as contemplated
by this Agreement;  (x) any individual capital expenditure in excess of $10,000,
or  aggregate  capital  expenditures  in excess of  $50,000,  or any  commitment
therefor; or (xi) any occurrence or circumstance which may be expected to result
in a material  adverse change in or affecting the business or financial  affairs
of DCI.

         (f) DCI has good and  marketable  title  to all of its  properties  and
assets, real, personal and

                                       -7-




mixed,  including those reflected in its Balance Sheet of May 31, 1996, free and
clear  of any  security  interests,  mortgages,  pledges,  liens,  encumbrances,
restrictions,  or  charges,  except for (i) those  described  on  Schedule  6(f)
attached hereto and made part herein,  (ii) liens shown on such Balance Sheet or
the Notes thereto as securing  specified  liabilities  set forth  therein,  with
respect to which no default exists, and except for minor  imperfections of title
and  encumbrances,  if any, which are not substantial in character,  amount,  or
extent,  do not detract from the value of the  properties  subject  thereto,  or
interfere  with the use of the  properties  for the  purposes for which they are
presently used, or otherwise  impair DCI's  operations,  and have arisen only in
the ordinary course of business.

         (g) Except as set forth on Schedule 6(g) attached  hereto and made part
herein,  DCI  presently  has  no  existing  leases,  contracts,   franchises  or
commitments,  or  agreements  to enter  into any of the same,  written  or oral,
extending  beyond  the date of  Closing.  Copies  of all  written  contracts  or
commitments, and a memorandum describing each oral contract or commitment listed
on  Schedule  6(g)  or any  other  Schedule  hereto,  together  with  a copy  or
description as aforesaid,  of each contract which requires the payment by DCI of
a sum in excess of $50,000 in the aggregate,  have been delivered to Centennial,
and are true,  complete  and correct in all  respects.  DCI has  complied in all
respects with all of the provisions of each such contract or commitment,  and of
all  other  contracts  and  commitments  to which  it is a party,  and is not in
default  under any of them,  except as described on Schedule 6(g) or except such
defaults which are not, individually or in the aggregate,  materially adverse to
DCI.

         (h) There is  attached to this  Agreement,  made part herein and marked
Schedule  6(h),  true and  complete  lists,  as of the  date of this  Agreement,
setting forth:

                  (i) The names and, if  available,  residence  addresses of all
directors,  officers  and  Shareholders  of DCI,  and the number of Common Stock
owned by such Shareholders;

                  (ii) The  names of all  persons,  if any,  holding  powers  of
attorney from DCI, and a summary statement of the terms therein;

                  (iii) A list  setting  forth the name and address of each bank
or other  institution in which DCI has  established  an account for  investment,
deposit,  checking, savings or borrowing, or through which credit is extended, a
brief description  therein,  and the names and titles of authorized  signers and
limits, if any;

                  (iv) A list of all  employees  and their  annual  compensation
together with their Social Security numbers; and

                  (v) A list of all employee benefits granted by DCI.

         At the request of Centennial,  DCI shall furnish to Centennial  further
information  relating to the matters set forth in the above described lists, and
copies  of any items  included  therein,  as well as any and all  other  matters
relating to the operations of DCI.

                                       -8-




         (i) Except for those matters disclosed on Schedule 6(i) attached hereto
and  made  part  herein,   there  is  no  action,   suit,   litigation,   claim,
administrative or governmental or quasigovernmental  investigation or proceeding
pending or, to the knowledge of DCI,  threatened against DCI, or its business or
properties.  DCI is not a  party  to,  or the  subject  of,  any  action,  suit,
litigation,    claim,    administrative    proceeding   or    governmental    or
quasi-governmental investigation relating to DCI, its operations,  properties or
business, or material to the transactions  contemplated  hereunder;  nor, to the
knowledge  of  DCI,  is  any  such  action,  suit,  litigation,   proceeding  or
investigation  threatened  or  contemplated,  nor, to the knowledge of DCI, does
there exist any basis for any of the same.

         (j) None of the representations and warranties made by DCI contained in
this Agreement, including all Schedules, nor in any written statement, document,
certificate or memorandum  furnished or to be furnished by DCI pursuant  hereto,
or in connection with the  transactions  contemplated  hereby,  contains or will
contain any untrue statement of material fact; and none of such representations,
warranties,  written statements,  documents,  certificates or memoranda omits or
will omit to state a material  fact  necessary  in order to make the  statements
contained herein or therein not misleading.

         (k) (i) Except as provided in Schedule  6(k) attached  hereto,  DCI has
duly filed all Federal, state, local, foreign and other tax returns, reports and
declarations  of estimated  tax required to be filed by it for all periods up to
and  including the Effective  Date (all such returns,  reports and  declarations
being  accurate  and  complete  in all  respects)  and has  paid or  established
adequate  reserves  for the  payments of all  federal,  state,  local or foreign
taxes,  assessments,   deficiencies,  levies,  imports,  duties,  license  fees,
registration fees, withholdings,  or other similar governmental charges, and any
interest,  penalties  or  additions  to tax imposed  thereon  (collectively  the
"Taxes") due or claimed to be due by any taxing authority. The amounts set up as
reserves  for Taxes on the Balance  Sheets of DCI as of October 31, 1995 and May
31,  1996 are  sufficient  for the  payment of all unpaid  Taxes for the periods
ended  October  31,  1995 and May 31,  1996,  and for any year or  period  prior
thereto,  and for which DCI may be liable in its own right or as a transferee of
the assets of or successor to any corporation, person, association, partnership,
joint venture or other entity. DCI will pay, or will establish adequate reserves
for the payment for all Taxes  payable for the period from May 31,  1996,  up to
and including the Effective Date.

                  (ii) All amounts  required to be withheld or  collected by DCI
for income  taxes,  social  security  taxes,  unemployment  insurance  and other
employee  withholding taxes have been so withheld or collected,  and either paid
to the  respective  governmental  authority  or set  aside for such  purpose  or
accrued and reserved against and entered upon the books of DCI.

                  (iii) The  Federal  income  tax  returns  of DCI have not been
audited by the Internal Revenue Service.  There is no action, suit,  proceeding,
audit,  investigation or claim pending or to the knowledge of DCI threatened, in
respect of any Taxes for which DCI may become liable,  nor has any deficiency or
claim for any Taxes  been  proposed  or  asserted.  No waiver of any  statute of
limitations  with respect to any taxable year has been executed by DCI; there is
no agreement,

                                       -9-




waiver  or  consent  providing  for an  extension  of time with  respect  to the
assessment  of any Taxes  against DCI,  and no power of attorney  granted by DCI
with respect to any tax matters is currently in force.

                  (iv) DCI has  never  been a member of an  affiliated  group of
corporations  filing a consolidated  federal or state income tax return. DCI has
not  consented  to the  application  to it of Section  341(f)(2) of the Internal
Revenue Code of 1986 (the "Code").

         (l) DCI has paid (and,  as to any of the  following  which are  payable
after the date of Closing and  determinable as of May 31, 1996, DCI has properly
reserved against in accordance with generally  accepted  accounting  principles)
all sales and use taxes,  social security taxes,  unemployment taxes, ad valorem
taxes,  property taxes, excise taxes, duties and imposts, and all other taxes of
every  kind,   character  or  description   imposed  by  any   governmental   or
quasi-governmental authority required to be paid by DCI for all periods prior to
the  Closing  Date.  There  are no  outstanding  notices  of  any  deficiencies,
adjustments,  changes in  assessments  or increases in tax rates with respect to
any such taxes. DCI has duly filed or caused to be filed all reports and returns
relating  to or  covering  all such  taxes and other  charges,  which are due or
required to be filed at or prior to the date herein.

         (m) There are no outstanding orders, injunctions,  decrees or judgments
of any nature existing  against DCI or any of its assets or properties.  DCI has
not  received  notice  of any kind of any  pending  or  threatened  claim by any
governmental or quasi-governmental  authority asserting that DCI has at any time
engaged in any unlawful  activity,  nor does there exist any material default of
which  DCI has  notice,  under  the  terms of any  existing  financing  or other
arrangement,  agreement  or  contract,  which  will  not be  cured  prior to the
declaration or such default.

         (n) There is a total of (i) 12,910.23 shares of DCI Common Stock issued
and  outstanding and a total of 150,000 such shares  authorized;  (ii) 20,269.85
shares of DCI Series B Preferred  Stock  issued and  outstanding  and a total of
20,270 of such shares  authorized;  and (iii)  47,710.15  shares of DCI Series C
Preferred  Stock  issued  and  outstanding  and a total of  50,000  such  shares
authorized.  All issued and outstanding shares of capital stock of DCI have been
duly authorized and validly issued and are fully paid and nonassessable, with no
personal liability attaching to the ownership therein,  and no shares of capital
stock were  issued in  violation  of any  preemptive  rights or Federal or state
securities  laws. There are no other shares of capital stock of DCI of any class
authorized,  issued or  outstanding.  There are no  outstanding  stock  options,
warrants,  calls, agreements, or statutory or nonstatutory preemptive rights, or
any other  rights  whatsoever,  to  purchase or  otherwise  obtain or demand the
issuance of any shares of Common Stock or Preferred Stock of DCI, in favor of or
held by any persons or entities  whatsoever,  except  those  options,  rights or
agreements  listed on Schedule 6(n) attached hereto and made a part herein,  all
of which options, rights or agreements shall be cancelled prior to the Effective
Date at no cost or expense to DCI.

         (o) Each Shareholder listed on Schedule 6(h),  attached hereto and made
a part herein,  is the record owner of all of the issued and outstanding  Common
Shares set forth opposite his name

                                      -10-




on Schedule 6(h). Collectively,  the Shareholders listed on Schedule 6(h) own of
record all of the  capital  stock of DCI issued  and  outstanding.  There are no
restrictions  on transfer on any of the DCI Shares which would  prevent such DCI
Shares from being transferred to Centennial pursuant to the Merger.

         (p)  DCI is  not  indebted  to any  Shareholder  or to any  officer  or
director of DCI, or to any of their respective  spouses and/or children,  in any
amount whatsoever.  DCI is not primarily or secondarily liable in respect of any
obligation  of another  person or party.  DCI is not a party to any agreement or
arrangement  whereby it engages in a transaction  of any kind with any affiliate
except on terms and  conditions no less favorable to DCI than would be customary
for such transactions  between unaffiliated parties or upon terms and conditions
on which similar transactions with others could fairly be expected to be entered
into.  All  agreements  and  arrangements  with any  affiliate  are  fairly  and
accurately  described  in Schedule  6(p).  For  purposes of this  Section  6(p),
"affiliate"  shall mean any officer,  director or 10%  Shareholder of DCI or any
person or entity controlled by such officers, directors or Shareholders.

         (q) DCI has no  subsidiaries,  nor any investments in, nor ownership of
securities  of, any  business,  enterprise,  entity or  organization,  public or
private,  except  certificates  of deposit,  commercial  paper and similar money
equivalents, all as described on its Balance Sheet of May 31, 1996.

         (r) Except as described in Schedule 6(g), DCI is not a party to, nor is
it bound by, any contract,  agreement or  undertaking  with any persons,  for or
related to personal  services  rendered  or to be  rendered to DCI,  made in the
ordinary  course of business  which may be terminated at the option of DCI at or
prior to the  Closing  Date,  or within  thirty  (30) days  thereafter,  without
liability upon DCI.

         (s)  (i)  Neither  DCI  nor  any  predecessor   has  ever   maintained,
participated  in or  been  obligated  to  contribute  to,  or has  ever  had any
liability with respect to, any Employee  Pension  Benefit Plan ("Plans") as such
term is defined in Section 3 of the Employment Retirement Income Security Act of
1974, as amended  ("ERISA"),  any Employee  Welfare Benefit Plan as such term is
defined  in  Section 3 of ERISA,  any  deferred  compensation  plan or any other
similar  employee  benefit  plan.  Neither  DCI nor  any  predecessor  has  ever
participated in, or been obligated to contribute to, any  Multiemployer  Plan as
such term is defined in Section  3(37) of ERISA as amended by the  Multiemployer
Pension Plan  Amendments Act of 1980. DCI is not, nor has it ever been, a member
of a "controlled  group of corporations" or an "affiliated  service group", or a
member under "common control" of any member, as defined in Sections 414(b),  (c)
and (m) of the Internal Revenue Code (the "Code").

                  (ii) Neither DCI nor any Plans  maintained by DCI from time to
time  in  effect,  nor  any  trusts  created  thereunder,  nor  any  trustee  or
administrator therein, has engaged in a  "prohibited transaction",  as such term
is defined in Section 4975 of the Code,  which could subject the Plans or any of
them,  any such trust,  or any trustee or  administrator  therein,  or any party
dealing with the

                                      -11-




Plans  or any such  trust,  to the tax or  penalty  on  prohibited  transactions
imposed by said Section 4975.  Neither any of the Plans nor any such trusts have
been terminated,  nor have there been any "reportable  events",  as that term is
defined in Section 4043 of ERISA,  since the effective date of ERISA.  Except as
expressly  disclosed  in Schedule  6(s),  none of the Plans  which are  employee
pension  benefit  plans,  and none of the trusts  created  thereunder,  has been
terminated  since  September  2,  1974.  No Plan  which is  subject to Part 3 of
Subtitle  B of Title I of ERISA or  Section  412 of the Code had an  accumulated
funding  deficiency  (as  defined in Section 302 of ERISA and Section 412 of the
Code),  whether or not waived, as of the last day of the most recent fiscal year
of such Plan to which Part 3 of Subtitle B of Title I of ERISA or Section 412 of
the  Code  applied.  No  material  liability  to the  Pension  Benefit  Guaranty
Corporation has been or is expected by the Company to be incurred by the Company
or any of its Subsidiaries with respect to any Plan, and there has been no event
or condition  which  presents a material risk of  termination of any Plan by the
Pension Benefit  Guaranty  Corporation.  The value of all accrued benefits under
all the Plans which are employee pension plans does not exceed the current value
of the assets of such Plans.

         The execution and delivery of this  Agreement and the  consummation  of
any  transaction  contemplated by this Agreement will not involve any prohibited
transaction within the meaning of ERISA or Section 4975 of the Code.

                  (iii)  Except as set forth on Schedule  6(s),  neither DCI nor
any predecessor has ever maintained or participated in any stock option or stock
bonus plan. No stock will be issued (except in connection  with stock options or
warrants  outstanding as of May 31, 1996) nor any options or warrants be granted
between the date of execution of this Agreement and the Closing.

         (t) DCI has good title to, or valid leases or licenses  for,  insurable
at regular  rates,  all of its  property and assets that are  necessary  for the
conduct of its business;  and its equipment  and real estate  (whether  owned or
leased) is in good order,  condition and repair,  and is in conformity  with all
applicable federal,  state and local laws, regulations and ordinances (including
but not limited to zoning).

         (u) All of DCI's  automobile  and other  equipment  leases,  employment
agreements and other material executory  agreements,  which are not described in
any other Schedule hereto are listed on Schedule 6(u) attached hereto and made a
part herein.  Complete  copies of each have been made  available  to  Centennial
prior to the execution of this  Agreement,  and they and each of them will be in
full force and effect on the Closing Date and thereafter for the benefit of DCI,
unaffected by the  transactions  contemplated by this Agreement,  with only such
additions and deletions  between the date of the execution of this Agreement and
the Closing Date as shall be approved in advance in writing by  Centennial.  DCI
has not received notice of default, nor has there been any default by DCI or any
party thereto,  under any of the  aforesaid.  All of the aforesaid are valid and
binding upon DCI.

         (v)  DCI  has  all  necessary   permits,   licenses  and   governmental
authorizations  required  for the  ownership  of its business as it is currently
being  operated,  all of which will be available  for the use and benefit of DCI
unaffected by the transactions contemplated by this Agreement. All of DCI's

                                      -12-




said  permits,   licenses  and  governmental   authorizations  relating  to  the
operations  of DCI are  currently  in force,  and are  listed on  Schedule  6(v)
attached hereto and made a part herein. Except as set forth on Schedule 6(v), no
consent, approval or authorization of any governmental authority or of any third
party (except such consents,  approvals or  authorizations  which are solely the
responsibility  of  Centennial  to obtain) is  required in  connection  with the
execution and delivery of this Agreement or any instrument  contemplated  hereby
or the  consummation  of the  transactions  contemplated  hereby.  DCI has fully
complied with all statutes, laws, ordinances, regulations and orders to which it
is subject, except where the failure to so comply would not materially adversely
affect the business, operations, prospects or financial condition of DCI.

         (w) All of DCI's  properties  and  operations  of a  character  usually
insured by companies of established  reputation engaged in the same or a similar
business  similarly  situated are adequately  insured,  by financially sound and
reputable  insurers,  against  loss  or  damage  of the  kinds  and  in  amounts
customarily insured against by such persons, and DCI carries, with such insurers
in customary amounts, such other insurance,  including larceny,  embezzlement or
other criminal  misappropriation  insurance and business interruption insurance,
as is usually carried by companies of established reputation engaged in the same
or a similar business similarly situated. Schedule 6(w) attached hereto and made
a part herein  contains a complete and correct list of all policies of insurance
of every kind and nature covering DCI, including without limitation, policies of
life, fire, theft, employee fidelity and other casualty and liability insurance,
indicating the insurer,  the policy number, the type of coverage,  the amount of
coverage and the expiration  date of each policy.  Such policies are and will be
at Closing in full force and effect,  and will be unaffected by the transactions
contemplated by this Agreement.  Complete and correct copies of each such policy
have been made available to Centennial prior to the execution of this Agreement.

         (x) DCI has no  agreements,  written or oral,  with any labor  union or
association.  DCI considers its relationships  with employees to be good and has
not experienced a work slowdown or stoppage due to labor problems.

         (y) No officer of DCI,  nor, to the  knowledge  of DCI, any director or
any employee of DCI who is also a  Shareholder  of DCI, has a direct or indirect
interest of any kind in any business entity which is competitive with or related
to the  business  of DCI.  The  provisions  of this  Section  6(y)  shall not be
construed to prevent or preclude  investments by any Shareholder in a company or
companies  whose stock is listed on a national  securities  exchange or actively
traded on the  over-the  counter  market,  which  investment  does not give such
Shareholder  the right to control or influence the policy  decisions of any such
company.

         (z) Schedule 6(z) hereto  correctly sets forth a true and complete list
of all patents, trademarks, trade names, service marks, copyrights, licenses and
similar  rights,  and any  applications  in  respect  therein,  and  inventions,
processes  and  formula  used by DCI in whole or in part for the  conduct of the
business,  all of which are owned by DCI free and clear of any and all licenses,
liens, claims, security interests, charges or encumbrances whatsoever, except as
set forth in said Schedule  6(z),  and no licenses which are in effect as of the
date of this Agreement have been granted by DCI

                                      -13-




to any third parties. All such patents,  trademarks, trade names, copyrights and
similar  rights  are valid and in good  standing  and do not  infringe  upon the
rights of third parties.  The operation of the business of DCI does not infringe
upon any registered patent, trademark,  trade name, copyright,  license or other
right,  or  invention,  process,  formula or trade  secret,  of any person.  The
present  conduct of DCI's business is not  materially  dependent upon any one or
more patents, trademarks, trade names, service marks, copyrights or licenses.

         (aa) Neither DCI, nor, to the knowledge of DCI, any director or officer
of DCI, nor, any  Shareholder  in connection  with the activities of DCI, has at
any time,  either  directly or  indirectly,  (i) entered  into any  arrangement,
written or oral, under or pursuant to which bribes, kickbacks,  rebates, payoffs
or other  forms of  illegal  or  improper  payments  have  been or will be made,
provided for or suffered, either directly or indirectly through agents, brokers,
distributors,  dealers or other  intermediaries;  (ii) made any  contribution of
monies,  services,  or property to any  political  party,  candidate  or elected
official for any purpose; (iii) made any contributions,  payments or gifts to or
for the private use of any governmental official, employee or agent where either
the  payment  or the  purpose of such  contribution,  payment or gift is illegal
under  the  laws of the  United  States;  (iv)  established  or  maintained  any

         13.      ARBITRATION

         (a) Any  dispute,  controversy  or claim  arising out of or relating to
this Agreement,  including the breach  therein,  shall be settled by an amicable
effort on the part of both parties.  An attempt to arrive at a settlement  shall
be deemed to have failed  thirty (30) days after  either  party so notifies  the
other party in writing,  and neither party shall  institute  arbitration  or any
related  proceeding  until  expiration  of that  notice  period.  If a  dispute,
controversy or claim arises under Section 5 of this Agreement, the 30 day period
provided for in this Section 13(a) shall be deemed to have lapsed  following the
time periods specified in Section 5(b).

         (b) If an attempt at settlement has failed,  and written notice therein
has been given as provided herein, any dispute, controversy or claim between the
parties  arising out of or in connection  with this Agreement (or any amendments
hereto or  subsequent  agreements),  including,  but not  limited  to, as to its
existence, validity, interpretation,  performance or non-performance, breach, or
damages,  including  claims in tort,  shall be decided  by  binding  arbitration
pursuant to the commercial  Arbitration  Rules, as amended and in effect January
1, 1996, of the American Arbitration Association, then in effect, (the "Rules"),
subject to the following:

                  (i) The arbitration shall take place in Boston, Massachusetts,
and in no other place.

                  (ii) Each party shall be entitled to designate one arbitrator.
The  arbitrators  so  chosen  shall  designate  a third  neutral  arbitrator  by
unanimous  vote  within  ten  (10)  days  of  their  designation.  That  neutral
arbitrator shall act as Chair to the arbitration.

                  (iii) The  arbitration  shall be conducted in accordance  with
the procedural laws of the United States Federal Arbitration Act, as amended, to
the extent not inconsistent with the Rules of this Section.

                  (iv) An arbitration  hearing shall be conducted not later than
30 days after selection of the neutral arbitrator.  At the arbitration  hearing,
each party may make written and oral  presentations  to the  arbitration  panel,
present testimony and written evidence, and examine witnesses.  Legal privileges
against disclosure shall apply.

                  (v) The  written  decision of the  arbitration  panel shall be
final and  binding,  and may be entered and  enforced in any court of  competent
jurisdiction.  Each party  waives any the right to a jury trial with  respect to
any decision of the arbitration panel.

                  (vi)  Each  party to the  arbitration  shall  pay the fees and
expenses of the  arbitrator it designates  and one-half of the fees and expenses
of  the  neutral  arbitrator  and  of  the  American  Arbitration   Association.
Notwithstanding  the foregoing,  the  arbitration  panel,  by majority vote, may
agree to assess  arbitration  costs  and the  costs and fees of the  arbitrators
against either party if it determines such party has brought or defended a claim
in bad faith.

confidential, or use or permit to be used any such name, style, logo or form, to
or by any person, firm, corporation, association or other entity, for any reason

         (b) DCI acknowledges that the restrictions  contained in Section 17(a),
in view of the nature of the business in which it is engaged, are reasonable and
necessary in order to protect its legitimate  interests,  and that any violation

relief   restraining  DCI  from  disclosing  any  such  records,   documents  or
information  or using or  permitting  to be used any such name,  style,  logo or
form,  or from being  employed by or  otherwise  rendering  any  services to any
person,  firm,  corporation,  association  or other entity to whom such records,
documents  or  information,  in whole or in part,  have  been  disclosed  or are
threatened to be disclosed.

         (c) Centennial and CAC recognize and acknowledge that during the course
of  negotiations  in connection  with this  Agreement,  and in  preparation  for

systems,  methods,  designs,  procedures,  books  and  records  relating  to its
operations,   personnel  and  practices,  as  well  as  records,  documents  and
information concerning its business activities,  practices, and procedures,  all
of which constitute and will constitute  valuable,  special and unique assets of
its business. Centennial and CAC therefore covenant and agree that if Closing is
not consummated  hereunder,  all copies of such  information will be returned to
DCI and neither Centennial nor CAC will ever at any time thereafter disclose any
part therein to any person, firm, corporation,  association or other entity, for
any  reason  or  purpose  whatsoever,  unless  such  information  was  known  to
Centennial prior to such negotiations, is subsequently made public by DCI or any
third party, is  subsequently  disclosed to Centennial or CAC by any third party
having a right to do so, or is required to be disclosed by law.

         (d) Centennial and CAC acknowledge that the  restrictions  contained in
subparagraph  18(c),  in view of the  nature  of the  business  in which  DCI is
engaged,  are  reasonable  and  necessary  in order to  protect  the  legitimate
interests of DCI, and that any  violation  therein  would result in  irreparable
injuries to DCI. Centennial and CAC therefore  acknowledge that, in the event of
a breach or threatened  breach of the provisions of this paragraph by Centennial
or by CAC,  DCI  shall  be  entitled  to  obtain  from any  court  of  competent
jurisdiction, preliminary and permanent injunctive relief restraining Centennial
and/or CAC as the case may be from  disclosing  any such  records,  documents or
information  to any  person,  firm,  corporation,  association  or other  entity
whatsoever.

         (e)  Nothing   contained  in  this  paragraph  shall  be  construed  as
prohibiting Centennial, CAC or DCI from pursuing any other remedies available to
either of them for any such breach or  threatened  breach of the  provisions  of
this Section 17,  including  recovery of damages and an equitable  accounting of
all earnings, profits and other benefits arising from such violation.

         18.      EMPLOYMENT AGREEMENTS

         CAC agrees to enter into  employment  agreements  with those  employees
designated  on  Schedule  18  herein on terms  and  conditions  agreed to by the
