Item 2. Acquisition or Disposition of Assets.

         On January 28, 1997, the Registrant and its wholly owned subsidiary,
INTERMAT Acquisition Corp., a Delaware corporation ("Merger Sub"), consummated
the acquisition of INTERMAT International Materials Management Engineers, Inc.,
a Texas corporation ("INTERMAT"). Pursuant to the Agreement and Plan of Merger
(the "Merger Agreement"), dated as of January 28, 1997, by and among the
Registrant, Merger Sub, INTERMAT and the holders of the outstanding Common
Stock of INTERMAT, INTERMAT was merged with and into Merger Sub (the "Merger").

         The consideration paid in the Merger (which was determined as the
result of arms'-length negotiations) consisted of short-term promissory notes
in the aggregate principal amount of $10,800,000, which notes were guaranteed
by the Registrant (the "Guaranteed Term Notes"), 625,000 shares of the
Registrant's Common Stock and subordinated promissory notes of Merger Sub,
guaranteed by the Registrant, in the aggregate principal amount of $1,400,000,
payable on January 28, 2000 and bearing interest at the rate of 9% per annum.

         The Guaranteed Term Notes were paid in full by Merger Sub on January
29, 1997 in accordance with their terms with cash contributed to Merger Sub's
capital by the Registrant from the Registrant's available cash.

         INTERMAT is a leading provider of materials cataloguing products and
services. INTERMAT has developed proprietary cataloguing technology which
allows users to organize and consolidate their inventories of maintenance,
repair and operations materials, identify and eliminate duplicate items and
determine alternative items and their sources. The Registrant intends to
continue to use the acquired assets in connection with the operation of
INTERMAT's business.

which Tax Returns have not yet been filed. All Taxes of INTERMAT have been paid
or adequately provided for and neither INTERMAT nor any of the Stockholders
knows of any proposed additional Tax assessment against INTERMAT not adequately
provided for in the November 30, 1996 Balance Sheet. In the ordinary course,
INTERMAT makes adequate provision on its books for the payment of Taxes
(including for the current fiscal period) owed by INTERMAT. INTERMAT validly
elected under Section 1362(a) of the Internal Revenue Code of 1986, as amended
(the "Code"), to be treated as an S corporation for federal income tax purposes
for the taxable year beginning on July 1, 1989, and such election has not been
terminated or revoked. No comparable election has been made under the laws of
any state.

          Section 3.09. Absence of Undisclosed Liabilities. INTERMAT does not
have any indebtedness or liability, absolute or contingent, known or unknown,
which is not shown or provided for on the November 30, 1996 Balance Sheet other
than liabilities as shall have been incurred or accrued in the ordinary course
of business since November 30, 1996. Except as shown on the November 30, 1996
Balance Sheet, INTERMAT is not directly or indirectly liable upon or with
respect to (by discount, repurchase agreements or otherwise), or obliged in any
other way to provide funds in respect of, or to guarantee or assume, any debt,
obligation or dividend of any Person, except endorsements in the ordinary course
of business in connection with the deposit, in banks or other financial
institutions, of items for collection.

          Section 3.10. Equipment and Machinery; Tangible Assets. Schedule 3.10
sets forth a complete and correct list and brief description of each item of
Equipment and Machinery. As of the date of this Merger Agreement, INTERMAT has
good title to the Equipment and Machinery and other properties and assets owned
by it, free and clear of all title defects, objections and Liens (other than the
Lien of current property Taxes and assessments not in default, if any). INTERMAT
does not own any real property. Except as set forth on Schedule 3.10, INTERMAT
holds good and transferable leaseholds in all of the Equipment and Machinery and
other properties and assets leased by it, in each case under valid and
enforceable leases. INTERMAT is not in default with respect to any item of
Equipment and Machinery or other property or asset purported to be leased by it,
and no event has occurred that constitutes or with due notice or lapse of time
or both may constitute a default under any lease thereof. All facilities,
machinery, equipment, fixtures and other properties owned, leased or used by
INTERMAT (including the Equipment and Machinery) are in good operating condition
and repair, are reasonably fit and usable for the purposes for which they are
being used, are adequate and sufficient to carry on INTERMAT's business as
presently




                                       12
<PAGE>


conducted and as proposed by INTERMAT to be conducted, and conform in all
material respects with all applicable ordinances, regulations and laws.

          Section 3.11. Intellectual Property; Intangible Assets.

          (a) Schedule 3.11 sets forth a complete and correct listing of the
Intellectual Property owned by INTERMAT or used in its business. All
Intellectual Property listed on Schedule 3.11 is owned by INTERMAT, free and
clear of all Liens, and is not known to be the subject of any challenge. Except
as set forth on Schedule 3.11, INTERMAT is not a licensee of any Intellectual
Property rights. As of the date hereof, there are no unresolved claims made and
there has not been communicated to INTERMAT or any of the Stockholders the
threat of any claim that the holder of such Intellectual Property is in
violation or infringement of any Intellectual Property, including patent,
service mark, trademark, trade name, trademark, service mark or trade name
application or registration, copyright or copyright application or registration
of any other Person. INTERMAT is the owner of the patents, patent licenses,
trade names, trademarks, service marks, brand marks, brand names, copyrights,
know-how, trade secrets, formula and other proprietary and Intellectual Property
rights necessary for the conduct of INTERMAT's business as now conducted, and
without any known conflict with the rights of others, and INTERMAT has not
forfeited or otherwise relinquished any such patent, patent license, trade name,
trademark, service mark, brand mark, brand name, copyright, trade secrets,
know-how, formula or other proprietary right or Intellectual Property necessary
for the conduct of its business as conducted on the date hereof. INTERMAT owns
or has the right to use all computer software, software systems and databases
and all other information systems necessary for the operation of its business.

          (b) No present or former employee of INTERMAT and no other Person owns
or has any proprietary, financial or other interest, direct or indirect, in
whole or in part, in any Intellectual Property or in any application therefor
which INTERMAT owns, possesses or uses in its business as now and heretofore
conducted and following the Effective Time, the Surviving Corporation shall have
the exclusive, transferable right to use the Intellectual Property used by
INTERMAT in conducting its business. The Trademarks are valid, subsisting,
unexpired and enforceable in the United States and to the best knowledge of
INTERMAT and each of the Stockholder valid, subsisting, unexpired and
enforceable elsewhere in the world. All renewal fees and other maintenance fees
for registration of the Intellectual Property or applications therefor which
have fallen due on or prior to the date hereof have been paid and any such fees
arising prior to the Effective Time, will be paid. The Stockholders agree to
reasonably cooperate with the Surviving Corporation with regard to registering
Intellectual Property in the respective offices of any domestic or foreign
jurisdiction.

          (c) Schedule 3.11 sets forth a true and complete list of all of the
Intangible Assets and a summary description of each such item. There is no
restriction affecting the use of any of the Intangible Assets and, except as set
forth on Schedule 3.11, no license has been granted with respect thereto. Each
of the Intangible Assets is valid, is not currently being challenged, is not
involved in any pending or threatened administrative or judicial proceeding, and
does



                                       13
<PAGE>


not conflict with any rights of any other Person. INTERMAT's rights in and to
the Intangible Assets are sufficient and adequate in all respects to permit the
conduct of INTERMAT's business as now conducted and as proposed to be conducted,
and none of the services, products or operations of INTERMAT's business involves
any infringement of any proprietary right of any other Person.

          Section 3.12. Licenses and Permits. Schedule 3.12 sets forth a true
and complete list of all licenses, permits, franchises, authorizations and
approvals issued or granted to INTERMAT by the government of the United States,
any state or local government, any foreign national or local government, or any
department, agency, board, commission, bureau or instrumentality of any of the
foregoing (the "INTERMAT Licenses and Permits"), and all pending applications
therefor. Such list contains a summary description of each such item and, where
applicable, specifies the date issued, granted or applied for, the expiration
date and the current status thereof. Each INTERMAT License and Permit has been
duly obtained, is valid and in full force and effect, and is not subject to any
pending or threatened administrative or judicial proceeding to revoke, cancel,
suspend or declare such INTERMAT License and Permit invalid in any respect. The
INTERMAT Licenses and Permits are sufficient and adequate in all respects to
permit the continued lawful conduct of INTERMAT's business in the manner now
conducted and as proposed to be conducted, and none of the operations of
INTERMAT are being conducted in a manner that violates any of the terms or
conditions under which any INTERMAT License and Permit was granted. Except for
the Texas State Sales Tax Permit issued to INTERMAT, no INTERMAT License and
Permit will be affected by, or terminate or lapse by reason of, the transactions
contemplated by this Merger Agreement.

          Section 3.13. Compliance with Law. The operations of INTERMAT have
been conducted in accordance with all applicable laws, regulations, orders and
other requirements of all courts and other governmental or regulatory
authorities having jurisdiction over INTERMAT and its assets, properties and
operations, including, without limitation, all such laws, regulations, orders
and requirements promulgated by or relating to consumer protection, equal
opportunity, health, environmental protection, conservation, architectural
barriers to the handicapped, fire, zoning and building, occupation safety,
pension, securities matters and Intellectual Property matters. INTERMAT has not
received notice of any violation of any such law, regulation, order or other
legal requirement, and is not in default with respect to any order, writ,
judgment, award, injunction or decree of any national, state or local court or
governmental or regulatory authority or arbitrator, domestic or foreign. Neither
INTERMAT nor any of the Stockholders has knowledge of any proposed change in any
such laws, rules or regulations (other than laws of general applicability) that
would materially and adversely affect INTERMAT or its business or the
transactions contemplated by this Merger Agreement.

          Section 3.14. Litigation. There are no claims, actions, suits,
proceedings, labor disputes or investigations pending or, to the best knowledge
of INTERMAT and each of the Stockholders, threatened, before any national, state
or local court or governmental or regulatory authority, domestic or foreign, or
before any arbitrator of any nature, brought by or against any of the
Stockholders or INTERMAT or any of INTERMAT's officers, directors,


<PAGE>14


employees or agents involving, affecting or relating to INTERMAT's business or
Intellectual Property, or the transactions contemplated by this Merger
Agreement, nor is any basis known to any of the Stockholders or INTERMAT or any
of INTERMAT's directors or officers for any such action, suit, proceeding or
investigation. INTERMAT is not subject to any order, writ, judgment, award,
injunction or decree of any national, state or local court or governmental or
regulatory authority or arbitrator, domestic or foreign, that affects or might
affect INTERMAT's business or that would or might interfere with the
transactions contemplated by this Merger Agreement.

          Section 3.15. Contracts.

          (a) Schedule 3.15(a) sets forth a true and complete list of each
contract, agreement, instrument, commitment and other arrangement to which
INTERMAT is a party or otherwise relating to or affecting any of its assets,
including, without limitation, employment, severance or consulting agreements,
loan, credit or security agreements and customer contracts (each, a "Contract").
Each Contract is valid, binding and enforceable against INTERMAT and, to the
best knowledge INTERMAT and each of the Stockholders, the other parties thereto,
in accordance with its terms, and in full force and effect on the date hereof.
INTERMAT has performed all obligations required to be performed by it to date
under, and is not in default or delinquent in performance, status or any other
respect (claimed or actual) in connection with any Contract, and no event has
occurred which, with due notice or lapse of time or both, would constitute such
a default. With respect to each Contract, INTERMAT expects to comply with all
material terms thereof, all certifications and representations of INTERMAT with
respect thereto and all statutes and regulations applicable thereto.

          (b) Except as set forth on Schedule 3.15(b), no Contract requires the
consent of any Person in connection with the consummation of the transactions
contemplated hereby. The parties hereto acknowledge and agree that certain other
Contracts on Schedule 3.15(a) provide that such Contracts may not be assigned
without the prior written consent of the other party thereto but are otherwise
silent as to changes in control, and that INTERMAT will not seek the consents of
any such party in connection with the transactions contemplated hereby.

          Section 3.16. Receivables. All notes and accounts receivable payable
to or for the benefit of INTERMAT reflected on the November 30, 1996 Balance
Sheet, or acquired by INTERMAT after the date thereof and before the Effective
Time, except as set forth in Schedule 3.16, are or will be valid and legally
binding obligations of the obligor thereon, have been collected or are (or will
be) current and collectible within 90 days after the Effective Time in amounts
not less than the aggregate amount thereof (net of reserves established in
accordance with prior practice) carried (or to be carried) on the books of
INTERMAT, and are not subject to any defense, counterclaim or set-off. Schedule
3.16 sets forth a true and correct list of each note and account receivable of
INTERMAT at November 30, 1996 and December 31, 1996, in each case together with
the date each such receivable was created.

          Section 3.17. Inventories. The Inventory is stated on the November 30,
1996 Balance Sheet at not more than the lower of cost or net realizable value
and such Inventory (i) will be




                                       15

sold by INTERMAT in the ordinary course of its business within 90 days after the
Effective Time or (ii) is subject to repurchase by INTERMAT's customers pursuant
to valid and enforceable written agreements between such customers and INTERMAT
as in effect on the date of this Merger Agreement or (iii) shall be returned to
the applicable vendor for full credit.

          Section 3.18. Employee Plans.

          (a) Schedule 3.18 sets forth all pension, savings, retirement, health,
insurance, severance and other employee benefit or fringe benefit plans
maintained by INTERMAT (collectively referred to herein as the "Plans"). With
respect to the Plans, INTERMAT has delivered to SDI copies of: (i) all Plan
documents, and, where applicable, related trust agreements, and any related
agreements which are in writing; (ii) summary plan descriptions; (iii) the most
recent Internal Revenue Service determination letter relating to each Plan for
which a letter of determination was obtained; (iv) to the extent required to be
filed, the most recent Annual Report (Form 5500 Series and accompanying
schedules of each Plan and applicable financial statements) as filed with the
Internal Revenue Service; and (v) audited financial statements, if any.

          (b) (i) Each Plan conforms to, and its administration is in compliance
with, all applicable requirements of law, including, without limitation, ERISA
and the Code, and (ii) all of the Plans are in full force and effect as written,
and all premiums, contributions and other payments required to be made by
INTERMAT under the terms of any Pension Plan or Welfare Plan (each as defined
below) have been made or accrued.

          (c) Each Plan maintained by INTERMAT that is a pension plan as defined
in Section 3(2) of ERISA (a "Qualified Plan"), is qualified under Section 401(a)
of the Code, and a favorable determination letter has been issued by the
Internal Revenue Service with respect to each such qualified Pension Plan. No
Plan maintained by INTERMAT that is an employee welfare benefit plan as defined
in Section 3(1) of ERISA (a "Welfare Plan") is funded through a voluntary
employee beneficiary association as defined in Section 501(c)(9) of the Code.

          (d) Except for the Plan set forth on Schedule 3.18, neither INTERMAT
nor any trade or business (whether or not incorporated) which has ever been
under common control with INTERMAT within the meaning of Sections 414(b), (c),
(m) or (o) of the Code (each, an "ERISA Affiliate") has ever sponsored,
contributed to, or incurred any liability with respect to any pension plan as
defined in Section 3(2) of ERISA.

          (e) There are no multiemployer plans (as defined in Subsection 3(37)
of ERISA) to which INTERMAT or any ERISA Affiliate is, or has been, required to
make a contribution or other payment.

          (f) There has been no non-exempt prohibited transaction (within the
meaning of Section 4975 of the Code or Part 4 of Subtitle B of Title I of ERISA)
with respect to any Plan.




                                       16
<PAGE>



          (g) INTERMAT does not maintain any Plan providing post-retirement
benefits other than pension benefits provided under Qualified Plans
("Post-Retirement Benefits"). INTERMAT is not liable for Post-Retirement
Benefits under any Plan not maintained by INTERMAT. INTERMAT and each ERISA
Affiliate has complied in all material respects with the requirements of Section
4980B of the Code and Sections 601 to 608 of ERISA relating to continuation
coverage for group health plans.

          Section 3.19. Customers, Suppliers and Competitors.

          (a) Schedule 3.19 sets forth a complete and correct list of (i) all
customers (listed by account and sorted by size) during INTERMAT's last full
fiscal year; (ii) the suppliers by dollar volume of INTERMAT and the aggregate
dollar volume of purchases by INTERMAT from such suppliers for such fiscal year;
(iii) all distributors of any Products; and (iv) all representatives of INTERMAT
with respect to the business of INTERMAT. None of such customers, suppliers,
distributors or representatives has or, to the best knowledge of INTERMAT and
each of the Stockholders, intends to terminate or change significantly its
relationship with INTERMAT.

          (b) Neither INTERMAT, nor the Stockholders, nor any of INTERMAT's
officers or directors has any interest, nor during the last three years had any
interest, either by way of contract or by way of investment or otherwise,
directly or indirectly, in any Person other than INTERMAT that (i) provides any
services or designs, produces or sells any Product or Product lines or engages
in any activity similar to or competitive with any activity currently conducted
or currently proposed to be conducted by INTERMAT or (ii) has any direct or
indirect interest in any asset or property, real or personal, tangible or
intangible, of INTERMAT.

          Section 3.20. Insurance. Schedule 3.20 lists the fidelity bonds and
the aggregate coverage amount and type and generally applicable deductibles of
all policies of title, liability, fire, casualty, business interruption,
workers' compensation and other forms of insurance insuring INTERMAT. INTERMAT
has furnished a true, complete and accurate copy of all such policies and bonds
to SDI. All such policies and bonds are in full force and effect, underwritten
by financially sound and reputable insurers and sufficient for all applicable
requirements of law and will not be affected by or terminated or lapsed by
reason of the consummation of the transactions contemplated by this Merger
Agreement. INTERMAT shall maintain the coverage under all policies and bonds
listed on Schedule 3.20 in full force and effect through the Effective Time.
INTERMAT is not in default under any provision of any such policy of insurance
nor has received notice of cancellation of any such insurance. There is no claim
by INTERMAT pending under any of such policies or bonds as to which coverage has
been questioned, denied or disputed by the underwriters of such policies or
bonds. Neither INTERMAT nor any of the Stockholders has received any written
notice from or on behalf of any insurance carrier issuing such policies that
insurance rates will hereafter be substantially increased, that there will
hereafter be a cancellation, or an increase in a deductible (or an increase in
premiums in order to maintain an existing deductible) or non-renewal of existing
policies, or that alteration of any Equipment and Machinery, the




                                       17
<PAGE>


purchase of additional Equipment and Machinery or modification of any of the
methods of conducting INTERMAT's business, will be required or suggested. The
insurance maintained by INTERMAT is adequate in accordance with industry
standards, the requirements of any applicable leases and is in at least the
minimum amount required by currently applicable environmental regulations.

          Section 3.21. Transactions with Affiliates. Except as set forth on
Schedule 3.21, there have been no transactions between any of the Stockholders
and INTERMAT, or any director, officer or employee of INTERMAT. Except as set
forth on Schedule 3.21, to the best knowledge of INTERMAT and each of the
Stockholders, during the past three years none of the officers, directors or
employees of INTERMAT, or any spouse or relative of any of such Person, has been
a director or officer of, or has had any direct or indirect interest in, any
Person which during such period has been a supplier, customer or sales agent of
INTERMAT.

          Section 3.22. Change in Ownership. To the best knowledge of INTERMAT
and each of the Stockholders, the consummation of the transactions contemplated
by this Merger Agreement will not result in the loss of the benefits of any
Contract or any material relationship with any customer or supplier.

          Section 3.23. Labor Matters.

          (a) Schedule 3.23(a) lists all of INTERMAT's employees as of the date
hereof, together with each such employee's salary. Except as set forth on

agreements or contracts with officers or employees of INTERMAT that are not
terminable at will, or that provide for the payment of any bonus or commission;

last three years. INTERMAT has furnished to SDI complete and correct copies of
all such agreements (the "Employment and Labor Agreements"). INTERMAT has not
breached or otherwise failed to comply with any provisions of any Employment and
Labor Agreement, and there are no grievances outstanding thereunder.

strike, material slow down or material work stoppage, lockout or other
collective labor action; (iv) there is no representation claim or petition
pending before the



                                       18

Opportunity Commission or any state, local or foreign agency responsible for the
prevention of unlawful employment practices; and (vi) neither INTERMAT nor any

class of claims or lawsuits involving the same or similar Product or any product
distributed by or on behalf of INTERMAT which is pending or, to the best
knowledge of INTERMAT and each of the Stockholders, threatened, resulting from
an alleged defect in design, manufacture, materials or workmanship of any
Product or any product distributed or sold by or on behalf of INTERMAT, or any
alleged failure to warn, or from any breach of implied warranties or
representations; (ii) there has not been any Occurrence; and (iii) there has not
been, nor is there under consideration or investigation by INTERMAT, any Product

or on behalf of INTERMAT.

          (b) For purposes of this Section 3.24, the term "Occurrence" shall
mean any accident, happening or event which takes place at any time which is
caused or allegedly caused by any alleged hazard or alleged defect in
manufacture, design, materials or workmanship including, without limitation, any
alleged failure to warn or any breach of express or implied warranties or
representations with respect to, or any such accident, happening or event
otherwise involving any Product or any product distributed by or on behalf of
INTERMAT (including any parts or components), that is likely to result in a
claim or loss.

          Section 3.25. Environmental Matters. INTERMAT has obtained and
maintained in effect all licenses, permits and other authorizations required
under all applicable laws, regulations and other requirements of governmental or
regulatory authorities relating to pollution or to the protection of the
environment, health or safety ("Environmental, Health or Safety Laws") and is in
compliance with all Environmental, Health or Safety Laws and with all such

Stockholders has performed or suffered any act which could give rise to, or has
otherwise incurred, liability to any Person (governmental or not) under the
Comprehensive Environmental Response, Compensation and Liability Act, 42 U.S.C.
ss. 9601 et seq. or any other Environmental, Health or Safety Laws, nor have any
of the Stockholders or INTERMAT received notice of any such liability or any

                                       19
<PAGE>



pursuant to section 103 of such Act to any governmental agency with respect to
any of INTERMAT's operations or assets. Neither INTERMAT nor any of the
Stockholders is subject to, or the subject of, any investigation by, enforcement
order from or consent agreement with, any governmental authority with respect to
any Environmental, Health or Safety Laws. No hazardous substance, hazardous
waste, contaminant, pollutant or toxic substance (as such terms are defined in
any applicable Environmental, Health or Safety Law) ("Hazardous Substance") has
been released, placed, dumped or otherwise come to be located on, at, beneath or
near any property owned or leased by INTERMAT or any surface waters or
groundwaters thereon or thereunder. Neither INTERMAT nor any of the Stockholders

outstanding shares of INTERMAT Common Stock have been duly authorized and
validly issued and are fully paid and non-assessable. There are no outstanding

and in good faith. The assumptions used in the preparation of such projections
(a) are those INTERMAT believes are significant in forecasting the financial
results of INTERMAT and (b) reflect, as of the date made and for the relevant
periods presented, a reasonable estimate of the events, contingencies and
circumstances described therein. Such projections present INTERMAT's estimate of
the expected results of operations subject to certain uncertainties and
contingencies mentioned therein.

          SDI and Merger Sub jointly and severally represent and warrant to

bound or to which either of their properties or assets is subject, nor result in
the creation or imposition of any Lien upon any of the property of SDI or Merger
Sub, nor result in the cancellation, modification, revocation or suspension of
any of the licenses, permits, franchises, authorizations and approvals issued or
granted to SDI by the government of the United States, any state or local
government, any foreign national or local government, or any department, agency,
board, commission, bureau or instrumentality of any of the foregoing (the "SDI
Licenses and Permits").

          Section 4.04. Consents and Approvals. No filing with, and no consent,
waiver, authorization or approval of, any governmental or regulatory authority,
domestic or foreign, is required in connection with the execution and delivery
of this Merger Agreement by SDI or Merger Sub or the performance of their
respective obligations hereunder.

          Section 4.05. Stock Consideration. The shares of SDI Common Stock
constituting the Stock Consideration, when issued and delivered in accordance
with the terms of this Merger Agreement, will be duly and validly issued, fully
paid and nonassessable.

          Section 4.06. Business. SDI has caused to be delivered to INTERMAT
copies of SDI's Annual Report on Form 10-K for the fiscal year ended December
31, 1995, Quarterly Reports on Form 10-Q for each of the first three fiscal
quarters of SDI's 1996 fiscal year, the final Prospectus dated May 29, 1996
relating to the offering of 8,200,000 shares of SDI Common Stock, SDI's Proxy
Statement for its annual meeting of stockholders held in 1996 and such
additional documents as have been filed by SDI pursuant to the Exchange Act
since January 1, 1995 (collectively, the "SEC Reports"). The SEC Reports were
prepared and filed in material compliance with the rules and regulations
promulgated by the Commission under the Exchange Act, and do not contain any
untrue statement of a material fact or omit to state any material fact required
to be stated therein in order to make the statements contained therein, in light
of the circumstances under which they were made, not misleading.

          Section 4.07. Financial Statements. The audited consolidated balance
sheet of SDI as at December 31, 1995 and the unaudited consolidated balance
sheet of SDI as at September 30, 1996 included in the SEC Reports fairly present
the consolidated financial position of SDI as at the dates thereof, and the
related consolidated statements of operations, stockholders' equity and cash
flows for the fiscal periods ended on such dates fairly present the results of
operations and cash flows of SDI and its subsidiaries for the respective periods
indicated. All such financial statements, including the schedules and notes
thereto, were prepared in accordance with GAAP applied consistently throughout
the periods involved.

          Section 4.08. Tax Matters. All Tax Returns required to be filed before
the Effective Time in respect of SDI have been (or will have been by the
Effective Time) filed, and SDI has (or will have by the Effective Time) paid,
accrued or otherwise adequately reserved for the payment of all Taxes required
to be paid in respect of the periods covered by such Tax Returns and has (or
will have by the Effective Time) adequately reserved for the payment of all
Taxes with respect to periods ended at or before the Effective Time for which
Tax Returns have not yet been filed. All Taxes of SDI have been paid or
adequately provided for and SDI knows of no proposed additional tax assessment
against SDI not adequately provided for in the unaudited consolidated balance
sheet of SDI as at September 30, 1996 included in the SEC Reports. In the
ordinary course, SDI makes adequate provision on its books for the payment of
Taxes (including for the current fiscal period) owed by SDI.

          Section 4.09. Licenses and Permits. Each SDI License and Permit has
been duly obtained, is valid and in full force and effect, and is not subject to
any pending or threatened administrative or judicial proceeding to revoke,
cancel, suspend or declare such SDI License and Permit invalid in any respect.
The SDI Licenses and Permits are sufficient and adequate in all respects to
permit the continued lawful conduct of SDI's business in the manner now
conducted and as proposed to be conducted, and none of the operations of SDI are
being conducted in a manner that violates any of the terms or conditions under
which any SDI



                                       22
<PAGE>


License and Permit was granted. No such SDI License and Permit will be affected
by, or terminate or lapse by reason of, the transactions contemplated by this
Merger Agreement.

          Section 4.10. Compliance with Law. The operations of SDI have been
conducted in accordance with all applicable laws, regulations, orders and other
requirements of all courts and other governmental or regulatory authorities
having jurisdiction over SDI and its assets, properties and operations,
including, without limitation, all such laws, regulations, orders and
requirements promulgated by or relating to consumer protection, equal
opportunity, health, environmental protection, conservation, architectural
barriers to the handicapped, fire, zoning and building, occupation safety,
pension, securities matters and intellectual property matters. SDI has not
received notice of any violation of any such law, regulation, order or other
legal requirement, and is not in default with respect to any order, writ,
judgment, award, injunction or decree of any national, state or local court or
governmental or regulatory authority or arbitrator, domestic or foreign. Neither
SDI nor Merger Sub has knowledge of any proposed change in any such laws, rules
or regulations (other than laws of general applicability) that would materially
and adversely affect SDI or its business or the transactions contemplated by
this Merger Agreement.

          Section 4.11. Litigation. Except as set forth in the SEC Reports,
there are no material claims, actions, suits, proceedings, labor disputes or
investigations pending or, to the best knowledge of SDI or Merger Sub,
threatened, before any national, state or local court or governmental or
regulatory authority, domestic or foreign, or before any arbitrator of any
nature, brought by or against SDI or Merger Sub or any of their officers,
directors, employees or agents involving, affecting or relating to SDI's
business, or the transactions contemplated by this Merger Agreement, nor is any
basis known to SDI or Merger Sub or any of their directors or officers for any
such action, suit, proceeding or investigation. SDI is not subject to any order,
writ, judgment, award, injunction or decree of any national, state or local
court or governmental or regulatory authority or arbitrator, domestic or
foreign, that affects or might affect SDI's business or that would or might
interfere with the transactions contemplated by this Merger Agreement.

          Section 4.12. Accuracy of Information. None of SDI's or Merger Sub's
representations, warranties or statements contained in this Merger Agreement, or
in the exhibits hereto, contains any untrue statement of a material fact or
omits to state any material fact necessary in order to make any of such
representations, warranties or statements in light of the circumstances under
which they were made not misleading.

cooperation shall include, without limitation, timely furnishing to SDI all

included in such documents or would be helpful in obtaining any such required
consent, waiver, authorization or approval).

          Section 5.03. Access to Properties and Records. INTERMAT shall, and
each of the Stockholders shall cause INTERMAT to, afford to SDI, and to the
accountants, counsel and representatives of SDI, reasonable access during normal

properties, books, Contracts, commitments and Files and Records (including, but

and, during such period, shall furnish promptly to SDI all other information

          Section 5.05. Further Assurances; Reasonable Best Efforts. Upon the
request of SDI at any time after the Closing, each of the Stockholders shall
forthwith execute and deliver such further instruments and other documents as
SDI or its counsel may reasonably request to effectuate the purposes of this

Agreement, INTERMAT and each of the Stockholders will use their reasonable best
efforts to take, or cause to be taken, all action, and to do, or cause to be

transactions contemplated hereby.

          Section 5.06. Covenant Not To Compete.

          (a) Each Stockholder agrees that, for a period of five years after the

proprietor, member of a




                                       26
<PAGE>


partnership, or stockholder, investor, officer or director of a corporation, or
as an employee, agent, associate or consultant of any Person:

                    (i) Solicit or accept business (x) from any clients or
          prospects of INTERMAT, the Surviving Corporation or their affiliates
          or (y) from any former client who was such within the last two (2)
          years prior to the date of this Merger Agreement, if such business
          would be in competition with the Company or its affiliates or
          otherwise interfere with the customer relationships of the Company or
          its affiliates; or

                    (ii) Engage in the business of the type performed by SDI or
          its affiliates (including the Surviving Corporation).

          (b) Each Stockholder agrees that a monetary remedy for a breach of the
agreement set forth in Section 5.06(a) hereof will be inadequate and
impracticable and further agree that such a breach would cause SDI irreparable
harm, and that SDI shall be entitled to temporary and permanent injunctive
relief without the necessity of proving actual damages. In the event of such a
breach, each Stockholder agrees that SDI shall be entitled to such injunctive
relief, including temporary restraining orders, preliminary injunctions and
permanent injunctions as a court of competent jurisdiction shall determine, in
addition to any damages to which SDI may be entitled.

          Section 5.07. Non-Solicitation of Employees. Each Stockholder agrees,
for the five-year period commencing on the Effective Time, not to make, offer,
solicit or induce to enter into, any written or oral arrangement, agreement or
understanding regarding employment or retention as a consultant with any Person
who was, on the date hereof, a full-time employee of INTERMAT, without the
written consent of SDI.

          Section 5.08. Disclosure of Information. Each Stockholder recognizes
and acknowledges that the Company's trade secrets and confidential or
proprietary information, including such trade secrets or information as may
exist from time to time, and information as to the identity of customers of the
Company and its affiliates and other similar items, are valuable, special and
unique assets of the Company's business, access to and knowledge of which are
essential to the performance of the Stockholder's duties to the Company. Each
Stockholder will not, during or after the term hereof, in whole or in part,
disclose, and has not prior to the commencement of the term hereof disclosed,
such secrets or confidential or proprietary information to any person, firm,
corporation, association or other entity for any reason or purpose whatsoever,
except in furtherance of the Stockholder's duties to the Company. Each
Stockholder will not make use of any such property for his or her own purposes
or for the benefit of any person, firm, corporation or other entity (except the
Company) under any circumstances, during or after the term hereof, and each
Stockholder has not prior to the commencement of the term hereof made such use,
provided that after the term hereof these restrictions shall not apply to such
secrets or information which are then in the public domain (provided that she
was not responsible, directly or indirectly, for such secrets or information
entering the public domain without the Company's consent).

          Section 5.09. Expenses related to INTERMAT Lease. The Stockholders
shall be responsible for the any and all expenses incurred that are related to

obtain such consent ("Lease Consent Expenses").

          Section 5.10. Notice of Breach. Through the Effective Time, INTERMAT
and the Stockholders shall promptly give SDI written notice with particularity
upon having knowledge of any matter that may constitute a breach of any
representation, warranty, agreement or covenant contained in this Merger
Agreement.

          Section 6.01. Actions Before the Effective Time. SDI shall not take
any action which shall cause it to be in breach of any of its representations,
warranties, covenants or agreements contained in this Merger Agreement. SDI
shall use its reasonable best efforts to perform and satisfy all conditions to
Closing to be performed or satisfied by SDI under this Merger Agreement as soon
as possible, but in no event later than the Effective Time.

          Section 6.02. Consents and Approvals. SDI shall use its reasonable
best efforts to obtain all consents and approvals of third parties required to

Agreement.

request of the Stockholders at any time after the Closing, SDI or the Surviving
Corporation shall forthwith execute and deliver such further instruments and
other documents as the Stockholders or their counsel may reasonably request to

the conditions of this Merger Agreement, SDI and Merger Sub will use their

cause to be done, all things necessary, proper or advisable consistent with

practicable the transactions contemplated hereby.

          Section 6.04. Notice of Breach. Through the Effective Time, SDI and

                                OTHER AGREEMENTS

          Section 7.01. Stock Consideration and Debt Consideration.

          (a) Each Stockholder understands that the Stock Consideration and Debt
Consideration issued in the Merger have not been registered under the Securities
Act nor qualified under the Blue Sky laws of any state; and that the Stock
Consideration and Debt Consideration are being offered and sold to the
Stockholders pursuant to an exemption from such registration and qualification
based in part upon the representations of such Stockholder contained herein.

          (b) Each Stockholder represents that he or she is (i) an "accredited
investor," as defined in Rule 501 under the Securities Act, or (ii) has such
knowledge and experience in financial and business matters that he or she is
capable of evaluating the merits and risks of an investment such as the SDI
Common Stock and the Merger Sub Notes.

          (c) Each Stockholder acknowledges and agrees that he or she has
received and reviewed this Merger Agreement and has received and reviewed all
further information, if any, regarding SDI and Merger Sub necessary to make an
informed investment decision to invest in the SDI Common Stock and the Merger

and has received all information that he or she has requested from SDI, and has
been afforded a reasonable time to ask questions about the SDI Common Stock and
the Merger Sub Notes and the terms and conditions of the Merger Agreement, and
has received satisfactory answers to all such questions.

          (d) Each Stockholder acknowledges that he or she is fully aware of the
applicable transfer restrictions of the SDI Common Stock and the Merger Sub
Notes to be issued in the Merger, recognizes that it may be necessary to hold
the SDI Common Stock and the Merger Sub Notes indefinitely and can bear the
economic risk of his or her investment in the SDI Common Stock and the Merger
Sub Notes (including a complete loss of the investment).

          (e) Each Stockholder acknowledges and agrees that he or she is
acquiring the Stock Consideration and Debt Consideration issued in the Merger
for investment for his or her own account and not with a view to, or for resale
in connection with, the distribution or other disposition thereof. Each
Stockholders agree that he or she will not, directly or indirectly, offer,
transfer, sell, assign, pledge, hypothecate or otherwise dispose of
(hereinafter, "Transfer") any of the Stock Consideration or Debt Consideration
issued in the Merger unless (i) the Transfer is pursuant to an effective
registration statement under the Securities Act, and the rules and regulations
in effect thereunder, or (ii) counsel for such Stockholder (which counsel shall
be reasonably acceptable to SDI) shall have furnished SDI with an opinion,
satisfactory in form and substance to SDI, to the effect that no such
registration is required because of the availability of an exemption from
registration under the Securities Act.

          Section 7.02. Legend. Each certificate representing Stock
Consideration and each Merger Sub Note representing Debt Consideration shall
bear the following legend:

          "THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN
          REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, AND MAY NOT
          BE SOLD, TRANSFERRED, PLEDGED, HYPOTHECATED OR OTHERWISE DISPOSED OF
          IN THE ABSENCE OF (i) AN EFFECTIVE REGISTRATION STATEMENT FOR SUCH
          SECURITIES UNDER SAID ACT OR (ii) AN OPINION OF COMPANY COUNSEL THAT
          SUCH REGISTRATION IS NOT REQUIRED."

          Section 7.03. Delivery of Audited Financial Statements. By February
28, 1997, the Stockholders shall prepare and deliver to SDI audited balance
sheets of INTERMAT at December 31, 1994, 1995 and 1996 and related statements of
income, retained earnings and cash flows for the fiscal years then ended (the
"Audited Financial Statements"), and by March 15, 1997, the Stockholders shall
prepare and deliver to SDI an audited balance sheet of INTERMAT at the close of
business on the Closing Date (the "Closing Date Balance Sheet"). The Audited
Financial Statements and the Closing Date Balance Sheet shall be prepared in
accordance with GAAP applied on a basis consistent with that used in, and in
accordance with the same accounting principles applied in, the preparation of
the Historical Financial Statements. The Audited Financial Statements and the
Closing Date Balance Sheet shall be audited by Wallingford, McDonald, Fox & Co.,
P.C. and shall include the opinion of Wallingford, McDonald, Fox & Co., P.C.
that such accountants have audited the Audited Financial Statements and the
Closing Date Balance Sheet in accordance with generally accepted auditing
standards and that the Audited Financial Statements and the Closing Date Balance
Sheet were prepared in accordance with GAAP, applied on a basis consistent with
that used in, and in accordance with the same accounting principles applied in
the preparation of the Historical Financial Statements.

          Section 7.04. Tax Matters.

          (a) The Stockholders shall be responsible for the payment of all Tax
due with respect to taxable periods ending on or before the close of business on
the date of the Effective Time, including, but not limited to, Taxes relating to
the final S corporation Tax Return of INTERMAT for the period beginning January
1, 1997 and ending on the date of the Effective Time. Such final S corporation
Tax Return shall reflect INTERMAT's liability resulting from the imposition of
Tax under Section 1374 of the Code on "built-in gains." Where any such Tax
Return is required to be filed after the Effective Time, the Stockholders shall
prepare, or cause to be prepared, a draft of such Tax Return and shall furnish
such draft to SDI for review by SDI at least 30 days prior to the due date of
such Tax Return. SDI shall have the right to consent to the form and content of
such Tax Return, which consent shall not be unreasonably withheld. Where such
Tax Return is required to be filed by the Surviving Corporation, at least five
days prior to the due date for the Tax Return, the Stockholders shall pay over
to the Surviving Corporation the Tax due with respect to such Tax Return.

<PAGE>




          (b) Subject to Section 7.04(a), for taxable periods beginning before
and ending after the date of the Effective Time, SDI shall prepare or cause the
Surviving Corporation to prepare the Tax Returns required to be filed, if any,
for such periods and shall pay the Taxes due with respect to such Tax Returns;
provided, however, that SDI shall furnish a draft of such Tax Return to the
Stockholders at least 30 days prior to the due date for such Tax Return, and the
Stockholders shall pay SDI the portion of the Tax attributable to the taxable
period ending at the close of business on the date of the Effective Time. The
Stockholders shall have the right to review and consent to the form and
substance of such Tax Return, such consent not to be unreasonably withheld. For
this purpose, the Tax attributable to the period ending at the Effective Time
shall be based on a closing of the books of INTERMAT as of close of business on
the date of the Effective Time, except that in the case of deductions and
allowances based on time (such as depreciation), such deductions or allowances
shall be apportioned based on the ratio that the number of days in the portion
of the taxable period ending on the date of the Effective Time bears to the
total number of days in the taxable period.

          (c) SDI and the Stockholders agree to treat the Merger as a sale by
INTERMAT of all of its assets for federal and state income Tax purposes for an
amount equal to the Merger Consideration plus any liabilities assumed by SDI or
Merger Sub or to which such assets are subject to, other than liabilities for
which the Stockholders are liable under this Merger Agreement (the "Purchase
Price") The Purchase Price shall be allocated in accordance with Section
338(b)(5) of the Code and the Treasury Regulations thereunder using the
methodology set forth on Schedule 7.04(c). SDI shall determine the fair market
value of the assets of INTERMAT (the "Valuation"). The Valuation shall be
binding on all parties hereto unless the Stockholders shall, within 15 days of
notice to them of the Valuation, conclude in good faith that the Valuation is
manifestly unreasonable. SDI shall be under no obligation to have such Valuation
prepared by an independent appraiser. All values contained in the Valuation

                                  ARTICLE VIII

           SURVIVAL OF REPRESENTATIONS AND WARRANTIES; INDEMNIFICATION

          Section 8.01. Survival of Representations and Warranties. The
representations and warranties made by each of the parties hereto in this Merger
Agreement or in any instrument delivered pursuant to this Merger Agreement shall
survive the Closing and the consummation of the transactions contemplated by
this Merger Agreement and any investigation made by any party prior to the
Effective Time. Notwithstanding the foregoing, such representations and
warranties (except for the representations and warranties contained in Section
3.08 and 3.25 which shall survive indefinitely) shall terminate on the third
anniversary of the Closing Date. No claim or action for breach of any
representation or warranty shall be asserted or maintained by any party hereto
after the expiration of such representation or warranty pursuant to the
preceding sentence except for claims made in writing prior to such expiration or
actions (whether instituted before or after such expiration) based on any claim
made in writing prior to such expiration. In the event of a breach of any of
such representations, warranties or covenants, the party to whom such
representations, warranties or covenants have been made shall have all rights
and remedies for such breach available to it under the provisions of this Merger
Agreement or otherwise, whether at law or at equity, regardless of any
disclosure to, or investigation made by or on behalf of, such party on or before
the Effective Time.

          Section 8.02. Indemnification.

          (a) Each of the Beauchamps will jointly and severally, and each of
Enders and Gilpin (subject to the provisions of Section 7.05), Miday and Johnson
will severally and not jointly (i) indemnify and hold harmless SDI, Merger Sub
and the Surviving Corporation and each of their directors, officers, employees,
advisors, affiliates, agents and stockholders from and against any and all
losses, damages, liabilities, costs and claims arising out of, based upon or
resulting from (w) any inaccuracy of any of their respective representations or
warranties contained in or made pursuant to this Merger Agreement; (x) any
breach by INTERMAT or the Stockholders of any of their respective agreements,
covenants or obligations contained in or made pursuant to this Merger Agreement,
(y) any Taxes for which the Stockholders are responsible under Section 7.04
hereof, or (z) any Lease Consent Expenses for which the Stockholders are
responsible under Section 5.09 hereof, and (ii) reimburse SDI, Merger Sub and
the Surviving Corporation and each of their directors, officers, employees,
advisors,



                                      32
<PAGE>



affiliates, agents and stockholders for any and all fees, costs and expenses of
any kind related thereto (including, without limitation, any and all Legal
Expenses); provided, however, that in no case shall Enders, Gilpin, Johnson or
Miday be liable or responsible under this Section 8.02(a) for any amounts in
excess of the value of the respective Merger Consideration that such party is
entitled to receive hereunder and; provided, further, that in no case shall
Miday be liable or responsible under this Section 8.02(a) with respect to a
breach of Section 3.11 hereof for any amounts in excess of (i) if Miday shall
not have sold any shares of SDI Common Stock received by him as part of the
Merger Consideration (the "Miday Shares"), then Miday shall be liable for up to
an amount equal to the fair market value of the Miday Shares, which amount may
be paid by Miday by transferring to the claimant Miday Shares having a fair
market value equal to the claim, or (ii) if Miday shall have sold the Miday
Shares, Miday shall be liable for up to an amount equal to the proceeds received
by Miday upon the sale of the Miday Shares, or (iii) if Miday shall have sold
some but not all of the Miday Shares, Miday shall be liable first for up to an
amount equal to the proceeds received by Miday upon the sale of the sold Miday
Shares, and second for up to an amount equal to the fair market value of the
unsold Miday Shares (which amount may be paid by Miday by transferring to the
claimant the unsold Miday Shares having a fair market value equal to the claim).
For purposes of the preceding sentence, the fair market value of any Miday
Shares shall be calculated by multiplying the number of such shares by the
closing sale price of the SDI Common Stock on the Nasdaq National Market (or
other securities exchange on which the shares of SDI Common Stock are primarily
listed) on the date a claim is made hereunder. As used in this Section 8.02,
"Legal Expenses" of a Person shall mean any and all reasonable out-of-pocket
fees, costs and expenses of any kind incurred by such Person and its counsel in
investigating, preparing for, defending against or providing evidence, producing
documents or taking other action with respect to any threatened or asserted
claim of a third party or governmental entity.

          (b) SDI and Merger Sub will jointly and severally (i) indemnify and
hold harmless the Stockholders and each of their advisors, affiliates and
agents, as applicable, from and against any and all losses, damages,
liabilities, costs and claims (x) arising out of, based upon or resulting from
any inaccuracy of any representation or warranty of SDI or Merger Sub which is
contained in or made pursuant to this Merger Agreement or (y) arising out of,
based upon or resulting from any breach by SDI or Merger Sub of any of their
respective agreements, covenants or obligations contained in or made pursuant to
this Merger Agreement and (ii) reimburse the Stockholders and each of their
advisors, affiliates and agents, as applicable, for any and all fees, costs and
expenses of any kind related thereto (including, without limitation, any and all
Legal Expenses).

          (c) No party entitled to indemnification under this Section 8.02 shall
assert any claims or bring any action against another party hereto arising out
of this Merger Agreement until such time as the cumulative aggregate claims of
such party exceed $50,000; provided, however, that if the aggregate amounts due
to a party under this Section 8.02 exceed such threshold, then such party shall
have the right to recover the full amounts due without regard to such threshold.



                                       33
<PAGE>




          (d) Promptly after receipt by any person entitled to indemnification
under this Section 8.02 (an "indemnified party") of notice of the commencement
of any action in respect of which the indemnified party will seek
indemnification hereunder, the indemnified party shall notify the Person that is
obligated to provide such indemnification (the "indemnifying party") thereof in
writing, but any failure to so notify the indemnifying party shall not relieve
it from any liability that it may have to the indemnified party except to the
extent the indemnified party shall be materially prejudiced by such failure. The
indemnifying party shall be entitled to participate in the defense of such
action and to assume control of such defense with counsel reasonably acceptable
to the indemnified party; provided, however, that:

          (i) the indemnified party shall be entitled to participate in the
          defense of such claim and to employ counsel at its own expense to
          assist in the handling of such claim;

          (ii) the indemnifying party shall obtain the prior written approval of
          the indemnified party before entering into any settlement of such
          claim or ceasing to defend against such claim, if, pursuant to or as a
          result of such settlement or cessation, injunctive or other equitable
          relief would be imposed against the indemnified party or would
          otherwise restrict the future activity or conduct of the indemnified
          party; and

          (iii) the indemnifying party shall not consent to the entry of any
          judgment or enter into any settlement that does not include as an
          unconditional term thereof the giving by the claimant or plaintiff to
          each indemnified party of a release from all liability in respect of
          such claim.

          (e) After written notice by the indemnifying party to the indemnified
party of its election to assume control of the defense of any such action, the
indemnifying party shall not, except as otherwise provided, be liable to such
indemnified party hereunder for any Legal Expenses subsequently incurred by such
indemnified party in connection with the defense thereof. If the indemnifying
party does not assume control of the defense of such claims as provided in this
Section 8.02, the indemnified party shall have the right to defend such claim in
such manner as it may deem appropriate at the cost and expense of the
indemnifying party, and the indemnifying party will promptly reimburse the
indemnified party therefor in accordance with this Section 8.02. The
reimbursement of fees, costs and expenses required by this Section 8.02 shall be
made by periodic payments during the course of the investigation or defense, as
and when bills are received or expenses incurred.
