$0.01 per share,  of the Company  (individually a "Share" and  collectively  the

than Shares held in the Company's  treasury)  shall, by virtue of the Merger and

converted into and shall, subject to the terms and conditions hereof, become the
right to receive the Per Share Merger Consideration.

         (b)......At the Effective Time,  each  outstanding  share of the common
stock,  par value $.01 per share, of Acquisition Sub shall be converted into one
share of common stock, par value $.01 per share, of the Surviving Corporation.

         (c)......At  the Effective Time, each Share held in the treasury of the

Consideration to which SDI is entitled,  including wire instructions in the case

         (b)......At Closing and upon the surrender to the Payment Agent of each
certificate  representing  Shares  and a duly  executed  Letter  of  Transmittal
related  thereto  (each,  a "Letter of  Transmittal"),  SDI shall be entitled to
receive,  and the Payment Agent shall pay, in exchange therefor by check or wire
transfer (as selected by SDI) an amount in cash, without interest,  equal to the
product of (i) the number of Shares  evidenced by such  certificate and (ii) the
Per  Share  Merger  Consideration,   and  such  certificate  shall,  after  such
surrender, be marked as canceled.

                  (c)......In  the event of a transfer  of  ownership  of Shares
which is not registered in the transfer  records of the Company,  payment of the
Merger  Consideration  in respect  thereof  may be made to a  transferee  if the
         certificate representing such Shares is presented to the Payment Agent
accompanied  by all documents  required to evidence and effect such transfer and
by evidence  that any  applicable  stock  transfer  taxes have been paid.  Until
surrendered  as  contemplated  by this Section 2.9,  each  certificate  shall be
deemed  at any time  after the  Effective  Time to  represent  only the right to
receive upon such  surrender the Merger  Consideration  in respect of the Shares
represented by such certificate as contemplated by this Section 2.9.

         (d)......In  the event that any  certificate for Shares shall have been
lost, stolen or destroyed,  the Payment Agent shall issue in exchange  therefor,
upon the  making  of an  affidavit  of that fact by SDI,  in form and  substance
reasonably  acceptable to Buyer, such portion of the Merger Consideration as may
be required pursuant to this Agreement.

         (e)......Any  portion of the Merger Consideration made available to the
Payment  Agent  pursuant to this Section 2.9 that  remains  unclaimed by SDI two
years after the Effective Time will be returned to Buyer upon demand. If SDI has
not exchanged any Shares for the Merger  Consideration  in accordance  with this
Article 2 prior to that time, thereafter SDI will look only to Buyer for payment
of the Merger  Consideration  in respect of such Shares.  Neither  Buyer nor the
Company shall be liable to SDI for cash from the Merger Consideration  delivered
to a public official pursuant to any applicable  abandoned property,  escheat or
similar law.

transactions  contemplated  hereby have been duly and validly  authorized by the

right of termination, amendment, cancellation or acceleration or Lien) under any
of the terms  conditions or provisions of any note, bond,  mortgage,  indenture,
lease, license,  contract,  agreement or other instrument or obligation to which
Buyer or Acquisition  Sub or any of Buyer's other  subsidiaries is a party or by
which any of them or any of their  respective  properties or assets may be bound
or (c)  violate any order,  writ,  injunction,  decree,  law,  statute,  rule or
regulation  applicable  to  Buyer or  Acquisition  Sub or any of  Buyer's  other
subsidiaries or any of their respective properties or assets.

         SECTION 4.4. No Prior  Activities.  Except for obligations  incurred in
connection  with  its  incorporation  or  organization  of the  negotiation  and
consummation  of  this  Agreement  and  the  transactions  contemplated  hereby,

any  business  or activity of any type or kind  whatsoever  or entered  into any
agreement or arrangement with any Person.

         SECTION 4.5. Financial Ability; Capitalization. As of the Closing Date,
Buyer will have sufficient capital to fund the total consideration  contemplated

Acquisition Sub and MSI  Acquisition  Corp. will have sufficient cash on hand to
pay the total  consideration  contemplated  to be paid  hereunder  and under the
McCormick Merger Agreement.

         SECTION  4.6.  Brokers.  No  broker,  finder  or  investment  banker is
entitled to any brokerage,  finders or other fee or commission  from the Company
in connection  with the  transactions  contemplated by this Agreement based upon
arrangements made by or on behalf of Buyer or any of its affiliates.

         SECTION  4.7.  No  Additional  Representations;   Disclaimer  Regarding
Estimates and Projections.

         (a) Buyer and Acquisition Sub acknowledge that none of SDI, the Company
or their  affiliates or any other Person acting on behalf of the Company (i) has

representation or warranty as to the condition, merchantability,  suitability or
fitness for a  particular  purpose of any of the assets used in the  Business or

implied,  as to the accuracy or completeness  of any  information  regarding the
Company, its business or any of its affiliates, in each case except as expressly
set forth in this  Agreement or as and to the extent  required by this Agreement
to be disclosed on the Company Disclosure Schedule hereto. Buyer and Acquisition
Sub further  agree that none of SDI, the  Company,  or their  affiliates  or any
other  Person  acting on behalf of the  Company  will have or be  subject to any
liability,  except  as  specifically  set  forth in this  Agreement,  to  Buyer,
Acquisition  Sub or any other Person  resulting from the  distribution to Buyer,
for Buyer's use, of any such information, including the Confidential Information
Memorandum,  dated January 2000, distributed by First Union Securities, Inc. and
any  information,  document or material made available to Buyer in certain "data
rooms,"  management  presentations  or any  other  form  in  expectation  of the
transactions contemplated by this Agreement.

         (b) In connection with Buyer's investigation of the Company,  Buyer has
received  certain  projections,  including  projected  statements  of  operating
revenues and income from  operations  of the Business and the Company for fiscal
years 2000 through 2004 and certain  business plan  information  for such fiscal
years  and  succeeding   fiscal  years.   Buyer   acknowledges  that  there  are
uncertainties  inherent in attempting to make such  estimates,  projections  and
other forecasts and plans,  that Buyer is familiar with such  uncertainties  and
that Buyer is taking full  responsibility  for making its own  evaluation of the
adequacy and accuracy of all  estimates,  projections  and other  forecasts  and
plans so  furnished  to it  (including  the  reasonableness  of the  assumptions
underlying such estimates, projections and forecasts).  Accordingly, the Company
makes no representation or warranty with respect to such estimates,  projections
and other forecasts and plans (including the  reasonableness  of the assumptions
underlying such estimates, projections and forecasts).

the terms of that  certain  Confidentiality  Agreement  entered into between the

Agreement").

         SECTION 5.4. HSR Act.

         (a) Each of Buyer and the Company agrees to make an appropriate  filing
of a  Notification  and Report Form  pursuant to the HSR Act with respect to the
transactions  contemplated  hereby as promptly as  practicable  and in any event
within  five (5)  business  days of the date hereof and to supply as promptly as

         SECTION 5.7. Employee Benefits.

         (a) Buyer will provide the  employees of the Company who  following the
consummation  of the Merger continue to be employed by the Company or Buyer (the
"Affected  Employees")  and retirees of the Company,  for a period ending on the
first anniversary of the Effective Time, with compensation and employee benefits
of the type described in Section 3.9 of this Agreement  (other than stock option
or other plans  involving the potential  issuance or purchase on the open market
of  securities  of SDI or the Company or of Buyer)  which in the  aggregate  are
comparable  to those  currently  provided  by the Company to its  employees  and
retirees.  Buyer agrees and will cause the Surviving  Corporation  to agree that
(i) all  obligations  of the  Company  under any  "change of control" or similar
provisions  relating to employees  contained in any existing  contracts  and all
termination  or severance  agreements  with  executive  officers  identified  in
Section 3.9(b) of the Company Disclosure  Schedule will be honored in accordance
with their terms as of the date  hereof;  and (ii)  effective  as of the Closing
Date, the Buyer or the Surviving Corporation will establish and adopt, or become
a participating  employer in, a defined contribution plan, in form and substance
reasonably  acceptable to SDI,  offering the same or comparable  benefits to the
employees of the Company as are currently  available to the Company's  employees
under the Scot,  Inc.  Thrift  and  Profit  Sharing  Plan  currently  in effect.
Notwithstanding  the  foregoing,  except as provided in the preceding  sentence,
nothing  contained herein shall be construed as requiring Buyer or the Surviving
Corporation to continue any specific  employee  benefit plans or to continue the
employment  of any  specific  person,  or to provide  any  benefits  to Affected
Employees  following the  termination  of their  employment  with the Company or
Buyer.

         (b) Except as otherwise  provided in Section  5.7(a),  Buyer shall,  or
shall cause the Surviving  Corporation to, honor all unused  vacation,  holiday,
sickness and personal days accrued as of the Closing by the employees of Company
under the policies and practices of the Company as of the Effective Time. In the
event of any change in the welfare benefits  provided to any employee or retiree
of the  Company  under any  plan,  Buyer  shall,  or shall  cause the  Surviving
Corporation  to,  (i)  waive  all  limitations  as  to  preexisting  conditions,
exclusions  and waiting  periods  with  respect to  participation  and  coverage
requirements  applicable to the Affected  Employees or retirees  under such plan
(except to the extent that such conditions,  exclusions or waiting periods would
apply under the Company's  then existing plans absent any change in such welfare
plan  coverage) and (ii) provide each Affected  Employee and retiree with credit
for any co-payments and deductibles paid prior to any such change in coverage in
satisfying any applicable  deductible or out-of-pocket  requirements  under such
new or changed plan.  Buyer shall, or shall cause the Surviving  Corporation to,
provide each  Affected  Employee or retiree with credit for all service with the
Company under each employee  benefit plan,  policy,  program or  arrangement  in
which such Affected  Employee or retiree is eligible to  participate,  except to
the extent that it would result in a duplication of benefits with respect to the
same period of services.



<PAGE>




         SECTION  5.8.  Public  Announcements.  On and after the date hereof and
through the Effective Time, the Company, Acquisition Sub and Buyer shall consult
with each other before issuing any press releases or otherwise making any public
statements  with  respect to this  Agreement  or the  transactions  contemplated
hereby, and none of the parties shall issue any press release or make any public
statement prior to obtaining the other parties' written approval, which approval
shall  not be  unreasonably  withheld,  except  that no such  approval  shall be
necessary to the extent  disclosure  may be required by law or applicable  stock
exchange rule or any listing agreement of any party hereto.

         SECTION 5.9. Intentionally Omitted.

         SECTION 5.10.  Notification of Certain Matters.  The Company shall give
prompt notice to Buyer and Acquisition  Sub, and Buyer and Acquisition Sub shall
give prompt notice to the Company, of (a) the occurrence or nonoccurrence of any
event the  occurrence  or  nonoccurrence  of which  would be likely to cause any
representation  or  warranty  contained  in  this  Agreement  to  be  untrue  or
inaccurate in any material respect at or prior to the Effective Time and (b) any
material failure of the Company, Buyer or Acquisition Sub, as the case may be to
comply with or satisfy any covenant  condition or agreement to be complied  with
or satisfied by it hereunder; provided, however, that the delivery of any notice
pursuant to this  Section 5.10 shall not cure such breach or  non-compliance  or
limit  or  otherwise  affect  the  remedies  available  hereunder  to the  party
receiving such notice.

         SECTION 5.11. No Negotiation.  From the date of this Agreement  through
the  Effective  Time  (or  such  earlier  date,  if any,  as this  Agreement  is
terminated in accordance with its terms), the Company shall not, and shall cause
its officers, directors, employees,  representatives and agents not to, directly
or indirectly, solicit or initiate or encourage any inquiries or proposals from,
enter  into  discussions  or  transactions   with,  or  provide  any  non-public
information to, or consider the merits of any unsolicited inquiries or proposals
from, any person, corporation,  partnership or other entity or group (other than
Buyer or its  designees)  concerning any  transaction  involving the sale of the
Business  or assets  (other  than in the  Ordinary  Course of  Business)  or any
capital stock of the Company, or any merger, consolidation, business combination
or similar transaction involving the Company.

         SECTION 5.12. Non-Compete; Hiring Restrictions.

         (a) For a period of eighteen  (18) months  after the date  hereof,  SDI
agrees that neither it nor any of its affiliates will, without the prior written
consent of Buyer,  directly or indirectly  (whether  through any  partnership of
which it is a member,  through any trust in which it is a beneficiary or trustee
or through a  corporation  or other  association  in which it has any  interest,
legal or equitable,  or in any other capacity  whatsoever) acquire, by merger or
otherwise, substantially all of the assets or more than five percent (5%) of the
capital stock or other equity  interests in (i) the  aerospace  division of OEA,
Inc.,  (ii) the aerospace  division of  Ensign-Bickford  Industries,  (iii) UPCO
division of B.F. Goodrich Corporation,  (iv) Quantic Industries,  Inc., (v) FXC,
(vi) Hi-Shear Technology,  (vii) Pacific Scientific Co. and (viii) the bomb rack
product line of EDO Corporation.

         (b) For a period of two (2) years  after the Closing  Date,  SDI agrees
that it shall not (i) solicit, directly or indirectly, any full-time employee of
the Company  engaged in the Business or (ii) attempt to induce any such employee
to leave such employment;  provided,  however,  that the foregoing  restrictions
shall not prohibit SDI from  advertising  open  positions in  newspapers,  trade
journals,  on the  internet and in media of general  circulation  and hiring any
individual who responds to such general solicitation.

         (c) The parties  hereto  agree that the duration and area for which the
covenant not to compete set forth in this  Section  5.12 is to be effective  are
reasonable.  In the event that any court  determines that the time period or the
area or both of them, are  unreasonable and that such covenant is to that extent
unenforceable,  the parties  hereto agree that the covenant shall remain in full
force and effect for the  greatest  time  period and in the  greatest  area that
would not render it  unenforceable.  The parties intend that this covenant shall
be deemed to be series of separate  covenants  one for each and every  county of
each  and  every  state of the  United  States  of  America  and each and  every
political  subdivision of each and every country outside of the United States of
America  where this  covenant is intended to be  effective.  The parties  hereto
agree that damages are an inadequate  remedy for any breach of this covenant and
that Buyer shall,  whether or not it is pursuing any potential  remedies at law,
be  entitled  to  equitable  relief  in the  form of  preliminary  or  permanent
injunctions  without  bond or other  security  upon any  actual  breach  of this
covenant.

                         TERMINATION; AMENDMENT; WAIVER

         SECTION 7.1.  Termination.  This  Agreement may be  terminated  and the
Merger may be abandoned at any time prior to the Effective  Time whether  before
or after approval and adoption of this Agreement by the Company's stockholders:

         (a) by  mutual  written  consent  of  Buyer,  Acquisition  Sub  and the
Company;

         (b) by Buyer and  Acquisition  Sub or the  Company  if (i) any court of
competent  jurisdiction in the United States or other United States Governmental
Entity  shall  have  issued a final  order,  decree or ruling or taken any other
final action restraining, enjoining or otherwise prohibiting the Merger and such
order,  decree,  ruling or other action is or shall have become nonappealable or
(ii) the Merger has not been consummated by September 30, 2000; provided that no
party may terminate this Agreement  pursuant to this clause (ii) if such party's
failure to fulfill any of its  obligations  under this Agreement shall have been
the reason  that the  Effective  Time shall not have  occurred on or before said
date;

         (c) by the  Company  if (i)  there  shall  have  been a  breach  of any
representation  or warranty on the part of Buyer or Acquisition Sub set forth in
this Agreement or if any  representation or warranty of Buyer or Acquisition Sub
shall have become  untrue,  in either case such that the conditions set forth in
Section  6.2(a) would be incapable of being  satisfied by September 30, 2000 (or
as otherwise  extended  pursuant to Section 7.4) or (ii) there shall have been a
breach  by Buyer or  Acquisition  Sub of any of their  respective  covenants  or
agreements hereunder materially adversely affecting (or materially delaying) the
consummation  of the Merger,  and Buyer or Acquisition  Sub, as the case may be,
has not cured such  breach  within  twenty  business  days  after  notice by the
Company  thereof;  provided  that  the  Company  has  not  breached  any  of its
obligations hereunder; or

         (d) by Buyer and  Acquisition Sub if (i) there shall have been a breach
of any  representation  or warranty on the part of the Company set forth in this
Agreement or if any  representation or warranty of the Company shall have become
untrue in either case such that the conditions set forth in Section 6.3(a) would
be incapable of being satisfied by September 30, 2000 (or as otherwise  extended
pursuant to Section 7.4),  (ii) there shall have been a breach by the Company of
its  covenants  or  agreements  hereunder  materially  adversely  affecting  (or
materially  delaying) the  consummation  of the Merger,  and the Company has not
cured  such  breach  within  twenty  business  days  after  notice  by  Buyer or
Acquisition  Sub thereof  provided  that neither Buyer nor  Acquisition  Sub has
breached any of their respective obligations hereunder.

         SECTION 7.2. Effect of Termination. In the event of the termination and
abandonment  of this  Agreement  pursuant to Section 7.1, this  Agreement  shall
forthwith  become void and have no effect  without any  liability on the part of
any party hereto or its affiliates,  directors,  officers or stockholders  other
than the provisions of this Section 7.2 and Section 5.3(c), provided that in the
event that this  Agreement  is  terminated  or the  Closing  does not occur as a
result of Buyer's  breach of  Section  4.5  and/or  its  failure to satisfy  the
condition  set forth in  Section  6.3(i)  above  (such  termination,  a "Funding
Breach")  and for  reasons  other than (a) the  failure  to  satisfy  any of the
conditions  set forth in Section 6.1 above or the  Company's  failure to satisfy
any of the  conditions set forth in Sections  6.3(a),  6.3(b),  6.3(d),  6.3(f),
6.3(h), 6.3(j), 6.3(k), 6.3(l) or 6.3(m) above or (b) the failure to satisfy any
of the conditions set forth in Section 6.1 of the McCormick  Merger Agreement or
the failure of McCormick to satisfy any of the  conditions set forth in Sections
6.3(a),  6.3(b),  6.3(d),  6.3(f),  6.3(h),  6.3(j),  6.3(k)  or  6.3(l)  of the
McCormick  Merger  Agreement,  Wind Point Partners IV, L.P. ("Wind Point") shall
pay  to  the  Company,   within  five  (5)  business  days  of  such  event,   a
non-refundable  break-up fee of $894,000 (the  "Break-Up  Fee")  (together  with
interest  thereon at an annual  rate of  interest of 10% from the due date until
the  date the  Break-Up  Fee is paid)  in  immediately  available  funds by wire
transfer to a bank  account  designated  in writing by the Company  prior to the
date thereof. In addition,  Wind Point agrees to reimburse the Company on demand
for all reasonable fees and expenses (including  attorneys fees) incurred by the
Company or any of its  affiliates  in  connection  with the  collection  of such
Break-Up Fee or the enforcement of the Company's  rights under this Section 7.2.
Wind Point and the other parties hereto  acknowledge and agree that in the event
of a Funding  Breach,  (a) the  calculation  of the  Company's and SDI's damages
would be difficult or  impossible  to determine and that payment of the Break-Up
Fee represents  liquidated damages and not a penalty and (b) the payment of such
Break-Up Fee (and the fees and expenses  described in the immediately  preceding
sentence,  if any) shall be the sole  exclusive  remedy of the  Company  and SDI
under this  Agreement,  provided  that the  provisions  of this  Section 7.2 and
Section 5.3(c) shall survive and continue in full force and effect.

         SECTION 7.3.  Amendment.  This Agreement may be amended by action taken
by the Company,  Buyer and Acquisition Sub, but no amendment shall be made which
requires the approval of the stockholders of the Company or SDI under applicable
law without such  approval.  This Agreement  (including  the Company  Disclosure
Schedule) may be amended only by an  instrument  in writing  signed on behalf of
the parties hereto.

         SECTION  7.4.  Extension;  Waiver.  At any time prior to the  Effective
Time,  each party hereto may (a) extend the time for the  performance  of any of
the obligations or other acts of the other party,  (b) waive any inaccuracies in
the representations and warranties of the other party contained herein or in any
document   certificate  or  writing  delivered  pursuant  hereto  or  (c)  waive
compliance by the other party with any of the agreements or conditions contained
herein.  Any agreement on the part of any party hereto to any such  extension or
waiver shall be valid only if set forth in an instrument,  in writing, signed on
behalf of such  party.  The  failure  of any party  hereto to assert  any of its
rights hereunder shall not constitute a waiver of such rights.


                                    ARTICLE 8

                        INDEMNIFICATION; OTHER COVENANTS

         SECTION  8.1.  Survival of  Representations.  The  representations  and
warranties of the parties  contained  herein shall  survive the  Effective  Time
until  the  first  anniversary  of the  Effective  Time,  except  that  (a)  the
representations  and  warranties  under  Sections 3.2 and 3.3 shall  survive the
Closing and shall continue in full force and effect indefinitely  thereafter and
(b) the  representations and warranties under Section 3.11 shall not survive the
Closing.  Any  claims  under  this  Agreement  with  respect  to a  breach  of a
representation  and  warranty  must be  asserted  by written  notice  within the
applicable  survival  period  contemplated  by this  Section  8.1, and if such a
notice is given, the survival period for such  representation and warranty shall
continue  until the claim is fully  resolved.  The right to  indemnification  or
other remedy based on the representations,  warranties, covenants and agreements
herein will not be affected by any  investigation  conducted with respect to, or
any  knowledge  acquired  (or capable of being  acquired)  at any time,  whether
before or after the  execution  and  delivery of this  Agreement or the Closing,
with respect to the  accuracy or  inaccuracy  of or  compliance  with,  any such
representation,   warranty,  covenant  or  agreement.  All  representations  and
warranties  of each  party set forth in this  Agreement  shall be deemed to have
been made again by such party at and as of the Effective Time. The waiver of any
condition  based on the accuracy of any  representation  or warranty,  or on the
performance of or compliance with any covenant or agreement, will not affect the
right  to  indemnification  or  other  remedy  based  on  such  representations,
warranties, covenants and agreements.

         SECTION 8.2.  Indemnification.  (a)Subsequent  to the  Effective  Time,
subject to the limitations  described  below,  SDI shall indemnify the Surviving
Corporation and its officers, directors, employees,  shareholders,  partners and
agents ("Surviving Corporation Indemnified Parties"),  against, and hold each of
the Surviving Corporation  Indemnified Parties harmless from, any damage, claim,
loss,  cost,  liability  or expense,  including  without  limitation,  interest,
penalties,   reasonable   attorneys'   fees  and   expenses  of   investigation,
consequential  damages,  response  action,  removal  action or  remedial  action
(collectively  "Damages")  incurred by such  Surviving  Corporation  Indemnified
Parties,  together with interest on cash  disbursements in respect thereof at an
annual rate of interest of 8%,  based on actual days  elapsed  from the later of
the date a valid claim is made hereunder and the date of such disbursement until
the date the Surviving Corporation Indemnified Parties are indemnified therefor,
that are incident to, arise out of, in connection  with, or related to,  whether
directly   or   indirectly:   (i)  any   misrepresentation   or  breach  of  any
representation  or warranty of the Company contained in this Agreement or in any
agreement,  certificate or other instrument delivered by the Company pursuant to
this Agreement,  (ii) any breach or non-performance by the Company of any of its
covenants  or  agreements  contained  in  this  Agreement  or in any  agreement,
certificate  or other  instrument  delivered  by the  Company  pursuant  to this
Agreement,  (iii) all Liabilities for Taxes incurred by the Company with respect
to tax  periods or  portions  of tax  periods  ending on or prior to the Closing
Date, (iv) all  Liabilities  incurred by the Surviving  Corporation  Indemnified
Parties with respect to any Employee Plans  maintained or sponsored by SDI or to
which SDI is a party (the "SDI Plans");  or (v) all Liabilities  incurred by the
Surviving Corporation  Indemnified Parties with respect to the Scot, Inc. Thrift
and Profit Sharing Plan and Trust.

         (b) The Surviving  Corporation  shall  indemnify SDI and its affiliates
(excluding,  after the Effective Time, the Surviving  Corporation),  and each of
their respective  officers,  directors,  employees,  shareholders,  partners and
agents  ("SDI  Indemnified  Parties"),   against,  and  hold  each  of  the  SDI
Indemnified  Parties harmless from, any Damages incurred by such SDI Indemnified
Party,  together with interest on cash  disbursements  in respect  thereof at an
annual rate of interest of 8%,  based on actual days  elapsed  from the later of
the date a valid claim is made hereunder and the date of such disbursement until
the date the SDI Indemnified Parties are indemnified therefor, that are incident
to,  arise out of, in  connection  with,  or related  to,  whether  directly  or
indirectly: (i) any breach of any representation or warranty of the Buyer and/or
Acquisition Sub contained in this Agreement or in any agreement,  certificate or
other instrument  delivered by the Buyer and/or Acquisition Sub pursuant to this
Agreement or (ii) any breach or  non-performance by the Buyer and/or Acquisition
Sub of its  covenants  or  agreements  contained  in  this  Agreement  or in any
agreement,  certificate  or  other  instrument  delivered  by the  Buyer  and/or
Acquisition Sub.

         SECTION 8.3. Limitation on Indemnity.

         (a) Notwithstanding the foregoing,  (i) SDI shall have no obligation to
indemnify a Surviving Corporation Indemnified Party under Sections 8.2(a) unless
and until the  aggregate  of all Damages  suffered by such  Indemnified  Parties
hereunder  exceeds $250,000 (the  "Deductible"),  whereupon,  provided the other
requirements  of this Article 8 have been complied  with, SDI shall be liable to
indemnify  the  Indemnified   Parties  for  all  amounts  of  Damages  over  the
Deductible, (ii) no Surviving Corporation Indemnified Party shall have any right
to  indemnification  with  respect to any  individual  Damage which is less than
$10,000 and no such Damage shall be taken into account in determining whether or
the  extent  to which the  Deductible  has been met or  exceeded,  and (iii) the
aggregate  amount  of  Damages  recoverable  pursuant  to this  Article 8 by the
Surviving Corporation  Indemnified Parties shall be limited to ten percent (10%)
of the Merger Consideration.  Notwithstanding the foregoing, the limitations set
forth  above  shall not  apply to any  claims  based on (w) fraud or  fraudulent
misrepresentation,  (x) Taxes,  (y) the SDI Plans,  or (z) the Scot, Inc. Thrift
and Profit Sharing Plan and Trust.

         (b) Notwithstanding any other provisions of this Agreement,  the amount
of any  Damages  for  which  SDI shall be  liable  to  indemnify  the  Surviving
Corporation  with  respect to Taxes  shall be limited  to any  liability  of the
Surviving  Corporation  for Taxes of the  Company for tax periods or portions of
tax periods ending on or before the Closing Date.

         SECTION 8.4. Mitigation; Exclusivity of Remedy.

         (a) Prior to the assertion of any claims for indemnification under this
Article  8,  the  Indemnified  Party  shall  utilize  all  reasonable   efforts,
consistent with normal practices and policies and good commercial  practice,  to
mitigate all Damages for which it may seek  indemnification  from the Indemnitor
pursuant to this Article 8, and to minimize  the amount of such  indemnification
obligation by reasonably  pursuing the maximum  possible  insurance  recovery or
recovery from other  available  sources with respect to such Damages and nothing
herein will in any way  diminish  each  party's  common law duty to mitigate its
Damages.  Recovery  pursuant  to this  Article 8 shall in no event  include  any
special, indirect, incidental, punitive or consequential damages whatsoever.

         (b) The remedies in this Article 8 shall be the  exclusive  remedies of
the  parties  with  respect to any and all  matters  covered by this  Agreement,
except for the remedies of specific performance,  injunction and other equitable
relief;  provided,  however, that no party hereto shall be deemed to have waived
any  rights,  claims,  causes of action or  remedies  if and to the extent  such
rights,  claims, causes of action or remedies may not be waived under applicable
law or actual fraud,  intentional  misrepresentation  or active  concealment  is
proven on the part of a party by another party hereto.

         SECTION 8.5. Notice of Claims.

         (a) Any  Surviving  Corporation  Indemnified  Party or SDI  Indemnified
Party (the "Indemnified Party") seeking indemnification  hereunder shall, within
the relevant  limitation  period  provided for in Section 8.1 above (and, to the
extent  applicable,  Section 9.4 below),  give to the party obligated to provide
indemnification  to such Indemnified Party (the "Indemnitor") a notice (a "Claim
Notice") describing in reasonable detail the facts giving rise to any claims for
indemnification hereunder and shall include in such Claim Notice (if then known)
the  amount or the method of  computation  of the  amount of such  claim,  and a
reference to the provision of this  Agreement or any  agreement,  certificate or
instrument  executed  pursuant hereto or in connection  herewith upon which such
claim is based; provided, that a Claim Notice in respect of any action at law or
suit in equity by or against a third Person as to which  indemnification will be
sought  shall be given  promptly  after  the  action or suit is  commenced;  and
provided  further,  that  failure  to give such  notice  shall not  relieve  the
Indemnitor of its obligations  hereunder except to the extent it shall have been
prejudiced by such failure.

         (b)  Indemnitor  shall have  thirty  days after the giving of any Claim
Notice pursuant hereto to (i) agree to the amount or method of determination set
forth in the Claim  Notice and to pay such amount to such  Indemnified  Party in
immediately  available  funds or (ii) to  provide  such  Indemnified  Party with
notice that it disagrees with the amount or method of determination set forth in
the Claim Notice (the "Dispute Notice"). Within fifteen days after the giving of
the Dispute Notice,  a representative  of Indemnitor and such Indemnified  Party
shall negotiate in a bona fide attempt to resolve the matter.  In the event that
the  controversy is not resolved within thirty days of the giving of the Dispute
Notice,  the  parties  shall  proceed to  binding  arbitration  pursuant  to the
following procedures:

         (1) Any party may send another party  written  notice  identifying  the
matter in dispute and  invoking  the  procedures  of this  Section  8.5.  Within
fourteen (14) days,  each party involved in the dispute shall meet at a mutually
agreed  location in New York, New York,  for the purpose of determining  whether
they can resolve  the  dispute  themselves  by written  agreement,  and, if not,
whether  they can agree  upon a  third-party  arbitrator  to whom to submit  the
matter in dispute for final and binding arbitration.

         (2) If such parties fail to resolve the dispute by written agreement or
agree on the arbitrator within said fourteen (14) day period, any such party may
make written application to the American Arbitration Association ("AAA") for the
appointment of a panel of three arbitrators (collectively,  the "Arbitrator") to
resolve the dispute by arbitration.  At the request of AAA the parties  involved
in the dispute  shall meet with AAA at its offices  within ten calendar  days of
such request to discuss the dispute and the  qualifications and experience which
each party respectively believes the Arbitrator should have; provided,  however,
that the selection of the Arbitrator shall be the exclusive  decision of AAA and
shall be made within 30 days of the written application to AAA.

         (3) Within 120 days of the  selection  of the  Arbitrator,  the parties
involved in the dispute shall meet in New York, New York with such Arbitrator at
a place and time  designated by such  Arbitrator  after  consultation  with such
parties and present their respective  positions on the dispute.  The arbitration
proceeding shall be held in accordance with the rules for commercial arbitration
of the AAA in effect on the date of the initial  request by for  appointment  of
the  Arbitrator,  that gave rise to the dispute to be arbitrated  (as such rules
are modified by the terms of this Agreement or may be further modified by mutual
agreement  of the  parties).  Each party  shall have no longer than five days to
present its position,  the entire  proceedings before the Arbitrator shall be no
more than ten consecutive days, and the decision of the Arbitrator shall be made
in writing no more than 30 days  following  the end of the  proceeding.  Such an
award  shall be a final and  binding  determination  of the dispute and shall be
fully  enforceable as an arbitration  decision in any court having  jurisdiction
and  venue  over such  parties.  The  prevailing  party  (as  determined  by the
Arbitrator)  shall in addition  be awarded by the  Arbitrator  such  party's own
attorneys'   fees  and  expenses  in  connection  with  such   proceeding.   The
non-prevailing   party  (as  determined  by  the   Arbitrator)   shall  pay  the
Arbitrator's fees and expenses.

         SECTION 8.6. Third Person Claims.  If a claim by a third Person is made
against an Indemnified  Party,  and if such party intends to seek indemnity with
respect  thereto  under this Article 8, such  Indemnified  Party shall  promptly
notify the  Indemnitor  in writing of such claims,  setting forth such claims in
reasonable  detail.  The Indemnitor shall have twenty days after receipt of such
notice to undertake,  conduct and control,  through  counsel of its own choosing
and at its own expense,  the settlement or defense thereof,  and the Indemnified
Party  shall  cooperate  with it in  connection  therewith;  provided  that  the
Indemnified  Party may participate in such settlement or defense through counsel
chosen by such  Indemnified  Party  and paid at its own  expense;  and  provided
further that, if in the opinion of counsel for such Indemnified  Party, there is
a reasonable likelihood of a conflict of interest between the Indemnitor and the
Indemnified  Party,  the Indemnitor shall be responsible for reasonable fees and
expenses  of one  counsel  to such  Indemnified  Party in  connection  with such
defense.  So long as the  Indemnitor  is  reasonably  contesting  any such claim
actively and diligently in good faith,  the  Indemnified  Party shall not pay or
settle any such claim without the consent of the  Indemnitor.  If the Indemnitor
does not  notify the  Indemnified  Party  within  ten days after  receipt of the
Indemnified  Party's notice of a claim of indemnity  hereunder that it elects to
undertake the defense  thereof,  the  Indemnified  Party shall have the right to
undertake,  at Indemnitor's cost, risk and expense,  the defense,  compromise or
settlement  of the  claim but shall  not  thereby  waive any right to  indemnity
therefor  pursuant to this Agreement.  The Indemnitor shall not, except with the
consent of the Indemnified  Party, (a) consent to the entry of any judgment with
respect to the matter,  (b) enter into any  settlement  that  either  imposes an
injunction or other equitable  relief upon the Indemnified  Party,  (c) does not
include as an  unconditional  term  thereof  the giving by the Person or persons
asserting such claim to all Indemnified Parties (i.e., the SDI Indemnified Party
or the  Surviving  Corporation  Indemnified  Party,  as the  case  may be) of an
unconditional  release  from all  liability  with  respect  to such claim or (d)
settle or close any Tax  matters  if the  results  of a Tax audit or  proceeding
could  reasonably  be  expected  to  materially  and  adversely  affect  the Tax
reporting  position of the Company for any taxable period  beginning on or after
the Closing Date.

         SECTION 8.7. Calculation of Damages. The amount of any Damage for which
indemnification  is  provided  shall be reduced  to take  account of any net tax
benefit realized by the Indemnified Party arising from the incurrence or payment
of any such  Damage.  In  computing  the  amount  of any such tax  benefit,  the
Indemnified Party shall be deemed to recognize all other items of income,  gain,
loss,  deduction or credit before  recognizing any item arising from the receipt
of  any  indemnity  payment  hereunder  or  the  incurrence  or  payment  of any
indemnified Damage.

         SECTION  8.8.   Guarantee  by  JFLEI.   JFLEI  hereby   guarantees  the
obligations of SDI under Section  8.2(a) to indemnify the Surviving  Corporation
Indemnified  Parties for federal and state income tax  liabilities  of Scot with
respect to tax periods  during which Scot was,  for federal  and/or state income
tax purposes, a member of the consolidated group of corporations of which SDI is
the  common  parent  (the  "Guaranteed  Indemnification  Obligations").  JFLEI's
liability  shall extend to all amounts that  constitute  part of the  Guaranteed
Indemnification   Obligations  and  would  be  owed  by  SDI  to  any  Surviving
Corporation  Indemnified  Party  pursuant to Articles 8 and 9 hereof but for the
fact that they are  unenforceable  or not  allowable  due to the  existence of a
bankruptcy, reorganization or similar proceeding involving SDI; provided that no
payment  by  JFLEI  shall  be  required  hereunder  with  respect  to any of the
Guaranteed   Indemnification   Obligations   unless  and  until  the   Surviving
Corporation   Indemnified   Party   has   provided   notice  of  its  claim  for
indemnification to SDI as required pursuant to this Agreement and SDI has failed
to pay such  Guaranteed  Indemnification  Obligation  as and when due under this
Agreement.  JFLEI shall be subrogated to all rights of the Surviving Corporation
Indemnified  Parties against SDI in respect of any amounts paid to the Surviving
Corporation Indemnified Parties by JFLEI under this Section 8.8.

         SECTION 8.9. Subrogation Rights. Upon payment of any Damages under this
Article  8, an  Indemnitor  shall,  to the extent of such  Damages  paid by such
Indemnitor,  become subrogated to the rights of the Indemnified Party to recover
all or any part of such Damages from any third party.


                                    ARTICLE 9

                                   TAX MATTERS

         SECTION 9.1. Taxes.

         (a) The Company (or SDI) shall timely prepare and file with the IRS all
federal  income and with the  appropriate  state  agencies  any state income and
franchise Tax Returns  required to be filed by the Company (or SDI) with respect
to the Company for all taxable years ending on or before the Closing  Date,  and
shall pay all Taxes due (and shall be entitled to all  refunds)  with respect to
such Tax Returns.  Buyer shall timely prepare and file with the  appropriate Tax
authorities all other Tax Returns required to be filed by the Company, and shall
pay all Taxes due with respect to such Tax Returns, except for Taxes as to which
the Liability therefor was adequately  reserved on the Final Net Working Capital
Calculation).  The  Company  and  Buyer  shall  take all  actions  necessary  or
appropriate  to cause the taxable year of the Company to end on the Closing Date
to the extent  permitted by law. If the taxable year of the Company does not end
on the Closing Date,  then the income of the Company will be  apportioned to the
period up to and  including  the Closing  Date and the period  after the Closing
Date by closing the books of the Company as of the Closing Date.  Periodic Taxes
such as  personal  and real  property  taxes shall be  apportioned  based on the
number of days in each period.

         (b) Buyer shall pay all transfer Taxes resulting from the  transactions
contemplated by this Agreement.

         SECTION 9.2.  Tax Sharing  Arrangements.  Any Tax sharing  arrangements
between SDI and the Company shall be  terminated as of the Closing Date,  and no
amounts  shall be due and payable by either party  thereunder  at any time after
the Closing Date.

         SECTION 9.3.  Cooperation.  Buyer, SDI and the Company shall reasonably
cooperate,  and shall cause their respective  affiliates,  officers,  employees,
agents,  auditors and representatives  reasonably to cooperate, in preparing and
filing all Tax Returns, including maintaining and making available to each other
all records necessary in connection with Taxes and in resolving all disputes and
audits with respect to all Taxable periods relating to Taxes. Each of Buyer, SDI
and the Company  recognizes  that Buyer and SDI will need  access,  from time to
time,  after the  Closing  Date,  to  certain  accounting  and Tax  records  and
information held by the Company (or SDI) or Buyer,  respectively,  to the extent
such records and  information  pertain to events  occurring prior to the Closing
Date;  therefore,  SDI agrees,  and Buyer,  on behalf of itself  and,  after the
Closing  Date,  the Company,  agrees,  (a) to properly  retain and maintain such
records until such time as Buyer, the Company and SDI agree in writing that such
retention  and  maintenance  is no longer  necessary  and (b) to allow the other
party and its agents and representatives, at times and dates mutually acceptable
to the parties, to inspect, review and make copies of such records as such party
or its representatives may deem necessary or appropriate from time to time, such
activities to be conducted  during normal  business  hours and at the expense of
the requesting party.

         SECTION 9.4. Procedures Relating to Indemnification of Tax Claims. If a
claim shall be made by any taxing authority, which, if successful,  would result
in an indemnity  payment to Buyer or one of its  affiliates  pursuant to Section
8.2 (a "Tax  Claim"),  Buyer  shall  promptly  notify SDI in writing of such Tax
Claim, stating the nature and basis of such Tax Claim and the amount thereof, to
the extent known by Buyer. If notice of a Tax Claim is not given to SDI within a
sufficient period of time to allow SDI to effectively contest such Tax Claim, or
in reasonable detail to apprise SDI of the nature of the Tax Claim, in each case
taking into account the facts and circumstances  with respect to such Tax Claim,
SDI shall not be liable to the Company or Buyer or any of its  affiliates to the
extent  that SDI's  ability to  effectively  contest  such Tax Claim is actually
prejudiced as a result thereof.

         With respect to any Tax Claim, SDI shall control all proceedings  taken
in connection with such Tax Claim (including  selection of counsel) and, without
limiting the foregoing,  may in its sole discretion pursue or forego any and all
administrative  appeals,  proceedings,  hearings and conferences with any taxing
authority with respect thereto and may, in its sole  discretion,  either pay the
Tax claimed and sue for a refund where  applicable law permits such refund suits
or contest the Tax Claim in any permissible manner; provided,  however, that SDI
may not, without Buyer's consent, settle or close any tax matters if the results
of a Tax  audit  or  proceeding  are  likely  to  materially  increase  the  Tax
liabilities  of the  Company for any taxable  period  beginning  on or after the
Closing Date. The Company, Buyer and each of its affiliates shall cooperate with
SDI in contesting any Tax Claim,  which  cooperation shall include the retention
and (upon SDI's  request) the provision to SDI of records and  information  that
are reasonably  relevant to such Tax Claim, and making employees  available on a
mutually  convenient basis to provide  additional  information or explanation of
any material  provided  hereunder or to testify at proceedings  relating to such
Tax Claim.

         SECTION 9.5. Section 338(h)(10) Election.

         (a) If Buyer, in its sole discretion, decides that it wishes to have an
election made under Code Section  338(h)(10)  (and the Treasury  Regulations and
the administrative  pronouncements  thereunder) and any comparable  provision of
state or local Tax law (collectively,  a "Section  338(h)(10)  Election"),  with
respect to its purchase of the Shares of the Company,  Buyer shall notify SDI of
such intent. SDI agrees that it shall, in such event, along with Buyer,  jointly
make an express  election  under Code  Section  338(h)(10)  with  respect to the
Company and, at Buyer's  election,  any analogous  state election or any express
election under state law, if such state election or express election under state
law can be  made  without  adverse  effect  to SDI,  that  would  result  in the
treatment of the  transaction  contemplated  by this  Agreement as a sale by the
Company of its assets rather than as a sale by SDI of the Shares.  Buyer and SDI
will report any transactions that occur under this Agreement consistent with the
Section 338(h)(10) Election, and will take no position contrary thereto.

         (b) Buyer and SDI agree that the computation of the "modified aggregate
deemed sale price" (as defined in the  applicable  regulations  issued under the
Code) (the  "MADSP") of the assets of the Company  shall be in  accordance  with
Code Section 338. Buyer and SDI shall agree on the allocation of the MADSP among
the assets of the Company (the  "Allocation"),  and shall  prepare and file such
forms as may be required  under  Section  1060 of the Code to give effect to the
Allocation.

         (c) Buyer  and SDI  shall  each  provide  to the  other  all  necessary
information to permit the Section 338(h)(10) Election to be made. Buyer shall be
responsible for the preparation and filing of all forms or documents (including,
without  limitation,  IRS  Form  8023)  required  to be filed  with  any  taxing
authority in connection with the Section  338(h)(10)  Election (the "Section 338
Forms"). On the Closing Date, Buyer and SDI shall execute IRS Form(s) 8023 (or a
pro forma  Form(s)  8023 if the final  version is not as yet  prepared)  and any
forms required to make any elections under state or local law that are analogous
to a  Section  338(h)(10)  Election,  to the  extent  any  such  state  or local
elections  are made  pursuant to  paragraph  (a) of this  Section 9.5. SDI shall
execute and deliver to Buyer any other  documents  or forms as Buyer  reasonably
requires to complete properly the Section 338 Forms. SDI hereby authorizes Buyer
to file the Section 338 Forms and any other forms  referred to in the  preceding
sentence with the appropriate taxing authorities at Buyer's election,  and Buyer
shall  provide SDI with copies of such  Section 338 Forms after such Section 338
Forms are filed with the appropriate taxing authorities.  Buyer and SDI agree to
prepare  and  file  all Tax  Returns  on a basis  consistent  with  any  Section
338(h)(10)  Election and with an allocation of the MADSP that is consistent with
the Allocation of MADSP provided for in paragraph (b) of this Section 5A.1.

         (d) SDI shall  calculate the gain or loss, if any,  resulting  from the
Section  338(h)(10)  Election in a manner  consistent with the  determination of
MADSP and the Allocation and shall not take any position  inconsistent  with the
Section  338(h)(10)  Election,  the MADSP or the Allocation in any Tax Return or
otherwise,  unless  required to do so pursuant to a  "determination"  within the
meaning of Section 1313(a) of the Code.

         (e) Buyer shall  determine  its tax basis for the assets of the Company
in a manner  consistent with the  determination  of MADSP and the Allocation and
shall not take any position  inconsistent with the Section 338(h)(10)  Election,
the MADSP or the Allocation in any Tax Return or otherwise,  unless  required to
do so pursuant to a "determination" within the meaning of Section 1313(a) of the
Code.

                                  MISCELLANEOUS

         SECTION 10.1. Entire Agreement;  Assignment.  This Agreement (including
the  Company  Disclosure  Schedule),  the  McCormick  Merger  Agreement  and the
Confidentiality  Agreement  (a)  constitute  the entire  agreement  between  the
parties  hereto  with  respect to the  subject  matter  hereof and  thereof  and
supersede all other prior  agreements and  understandings  both written and oral
between the parties  with respect to the subject  matter  hereof and thereof and
(b) shall not be assigned by operation of law or otherwise;  provided,  however,
that Buyer and  Acquisition  Sub may  assign (i) any or all of their  rights and
obligations  under  this  Agreement  to any  subsidiary  of  Buyer  and  (ii) as
collateral  security  its rights  under this  agreement  to any party  providing
financing for the consummation of the transactions  contemplated  herein, but no
such assignment  shall relieve  Acquisition Sub of its obligations  hereunder if
such assignee does not perform such obligations.

         SECTION  10.2.  Validity.  If any  provision  of this  Agreement or the
application   thereof  to  any  Person  or   circumstance  is  held  invalid  or
unenforceable  the  remainder  of this  Agreement  and the  application  of such
provision to other persons or circumstances shall not be affected thereby and to
such end the provisions of this Agreement are agreed to be severable.

         SECTION 10.3. Notices. All notices, requests, claims, demands and other
communications  hereunder  shall be in writing  and shall be given (and shall be
deemed to have been duly given upon receipt) by delivery in person, by facsimile

         SECTION 10.4.  Governing Law. This  Agreement  shall be governed by and
construed in accordance with the laws of the State of Delaware without regard to
the principles of conflicts of law thereof.

         SECTION 10.5. Descriptive Headings. The descriptive headings herein are
inserted for convenience of reference only and are not intended to be part of or
to affect the meaning or interpretation of this Agreement.

         SECTION 10.6. Parties in Interest. This Agreement shall be binding upon
and inure  solely to the  benefit of each party  hereto and its  successors  and
permitted  assigns  and,  except as provided in Articles 2, 8 and 9,  nothing in
this Agreement  express or implied is intended to or shall confer upon any other
person any rights,  benefits or  remedies of any nature  whatsoever  under or by
reason of this Agreement.

         SECTION  10.7.  Personal   Liability.   Except  as  expressly  provided
hereunder,  this Agreement shall not create or be deemed to create or permit any
personal  liability  or  obligation  on the  part  of  any  direct  or  indirect
stockholder of the Company or Buyer or any officer,  director,  employee, agent,
representative or investor of any party hereto.

         SECTION 10.8. Expenses. Each of the parties hereto will bear all legal,
accounting,  investment  banking  and other  expenses  incurred  by it or on its
behalf in  connection  with the  transactions  contemplated  by this  Agreement,
whether or not such transactions are consummated;  provided,  however,  that (i)
the  Company  shall  bear  all of the  expenses  of SDI in  connection  with the
transactions  contemplated  by  this  Agreement,  if such  transactions  are not

other  parties,  for which damages,  even if available,  will not be an adequate
remedy.  Accordingly,  each party hereby  consents to the issuance of injunctive
relief by any court of  competent  jurisdiction  to compel  performance  of such
party's  obligations  and to the granting by any court of the remedy of specific
performance of its obligations hereunder.

         SECTION 10.10  Counterparts.  This  Agreement may be executed in one or
more  counterparts,  each of which shall be deemed to be an original  but all of
