INDUSTRY FUNDAMENTALS

CHANGING INDUSTRY DYNAMICS.

 . In recent years the environmental consulting/engineering and remediation
  industry has undergone several fundamental changes which have altered the
  market's growth dynamics. The changes include:

    - Limited enforcement of existing legislation and eroding regulatory
      drivers; projects are being driven by economic factors rather than
      government regulations;

    - Excess people capacity and slowing demand;

    - Uncertain government spending patterns; and 

    - More onerous contract terms.

 . AS A RESULT OF THESE FUNDAMENTAL BUSINESS CHANGES, ALL OF THE PARTICIPANTS IN
  THE INDUSTRY HAVE EXPERIENCED SUBSTANTIAL DETERIORATION IN REVENUE GROWTH AND
  PROFITABILITY OVER THE PAST SEVERAL YEARS, WHICH HAS LED TO SIGNIFICANT STOCK
  PRICE DECLINES AND LIMITED ACCESS TO CAPITAL.

INDUSTRY FUNDAMENTALS (CONT'D)

DETERIORATION IN FINANCIAL PERFORMANCE

 .  Over the past several years as the government and commercial marketplace have
   become increasingly competitive, most industry participants have seen a 
   deterioration in their financial performance.

   . Margins have eroded due to overcapacity and fierce price competition; the 
     marketplace demands cost efficiencies.
   . Earnings predictability is inconsistent at best due to the dependence on
     the government marketplace (DOD, DOE and EPA).

INDUSTRY FUNDAMENTALS (CONT'D)

STRATEGIES TO OVERCOME CHANGING INDUSTRY DYNAMICS.

  . Companies are attempting to overcome many of the challenges in the
    environmental consulting/engineering and remediation industry through a
    variety of strategies.

       - Pursuing new market opportunities, i.e. Brownfield sites,
         international, environmental technologies;

       - Expansion within the "needs" priority, focusing on both the water and
         solid waste markets;

       - Consolidation, including joint-venturing;

       - Restructuring, primarily through overhead reductions;

       - Improvement of the balance sheet by more aggressive working capital
         management; and
       
       - Capacity rationalization.

  . Most industry participants are focused on acquisition opportunities to
    further diversify away from difficult trends within the hazardous waste
    market.

 .   COST CUTTING initiatives that have included an overall            .   Cost structure of Scotty has been significantly reduced. 
    rationalization of the organization and the Company's                 S,G&A has dropped approximately 260 bps over the past
    infrastructure. Emphasis has been put on leveraging the               24 months.
    resources of the Company functionally rather than on
    traditional branch offices, which has led to seven office 
    closures, movement of the corporate office, as well as 
    rebalancing of labor, as 135 employees were eliminated in 
    October, 1996.

 .   IMPROVEMENT OF THE COMPANY'S FINANCIAL POSITION AND BALANCE       .   Strong financial position with $62 million in cash and
    SHEET primarily through the relationship with the Carlyle             35% debt-to-capitalization (debt includes liabilities of
    Group, a Washington, D.C. based merchant bank. Through                discontinued operations).
    Carlyle's $45 million investment and their ongoing 
    relationship, Scotty now has the opportunity to aggressively 
    pursue acquisition opportunities.

SCOTTY

   INITIATIVE/STRATEGY

 .  AGGRESSIVE CONSOLIDATION STRATEGY in which the Company expects to: (i) 
   significantly increase its scale in order to drive profitability, and (ii)
   diversify its concentration away from the hazardous waste market and broaden
   the Company's capabilities (75% of business is in hazardous waste market).

 .  PURSUE NEW MARKET OPPORTUNITIES, such as Brownfield properties and 
   international markets, in order to enhance growth.

   INITIAL RESULTS

 .  With the acquisition of Spock, Scotty will be the largest industry 
   participant and one of the lowest cost service providers.  The Company is
   actively pursuing additional opportunities with a focus on diversification
   and international opportunities.

 .  Numerous Brownfield projects underway, development of software products--
   Environmental Information Management, Technology Development lab established
   in Oak Ridge and an investment in a Taiwanese environmental services company.

    bidding efforts.

  . Other economic benefits.

    - Rationalization of excess capacity.

    - Increased operating leverage should enhance profit margins.


  . The two companies have significant overlap.

    - Geographic coverage.

    - Service offerings.

MECHANICS OF THE TRANSACTION


  . Scotty will commence a tender offer for 14.4 million of Spock's outstanding 
    shares for $11.50 in cash.

  . Immediately prior to the close of the tender offer, Spock will spin-off its 
    stake in NSC Corporation (4.01 million shares) to its shareholders.

  . Following the tender offer, Spock will repurchase 17% of its outstanding
    shares (4.8 million) from Waste Management, Inc. for $11.50 in cash.

  . In the second step, the remaining Spock shares will be converted into Scotty
    shares at an exchange rate of 1.39 to 1.00 to complete the merger.

  . Scotty will finance the tender offer with a bridge facility expected to be
    provided by Citibank and Bank of Boston.

  . At the close of the transaction, the bridge facility will then be rolled 
    into a combination term loan/revolver which will also be used to refinance
    both Scotty's and Spock's outstanding debt.

  . The total transaction value is approximately $366.8 million.

SCOPE OF ASSIGNMENT AND VALUATION METHODOLOGY

     .  As part of DLJ's engagement letter dated December 22, 1997, DLJ has been
requested to provide a fairness opinion for the proposed acquisition of Spock by
Scotty.

     .  DLJ participated in the discussions between the managements of Spock and
Scotty for due diligence and negotiating the merger agreement.

     .  DLJ reviewed the stock price performance and trading activity of Spock's
and Scotty's common stock.

     .  DLJ employed several valuation methodologies for Spock.

          - Comparable company analysis.
          - Comparable transaction analysis.
          - Discounted cash flow analysis.

     .  Valuation of Spock was based upon Spock's management projections which 
were reduced by Scotty management.

     .  DLJ also valued Scotty, to ensure that the market value is reasonable.

          - Comparable company analysis.
          - Discounted cash flow analysis.

 .  BT ALEX. BROWN (11/12/97) -- On October 30, the Company reported 3Q EPS of
   $0.18, in line with expectations. Strong margins offset a 10% shortfall in
   revenue, relative to our expectations. The recently acquired government
   outsourcing business posted strong results, while the core remediation
   business was weaker than expected, with the weakness coming from the
   government sector. The strong margins in the quarter reflected the unexpected
   mix of revenue (more outsourcing, less remediation) and the benefits of
   SPOCK's focus on reducing costs. The Company indicated that it would focus on
   growing its outsourcing business through internal market development and
   acquisitions. The Company is pursuing several major remediation contracts
   that could improve revenue visibility. We have raised our 1998 EPS estimate
   to $0.62 from $0.58 to reflect better margins driven by revenue mix and cost
   reduction efforts. We have maintained our "market perform" investment rating
   on the shares due to limited visibility on the remediation segment (83% of
   revenue in 3Q).

 . DONALDSON,LUFKIN & JENRETTE (10/24/97) -- SCOTTY's fiscal second quarter
  results of $0.04 (compared with a $0.17 operating loss a year ago) was in-line
  with our $0.04 estimate. Despite the ongoing challenges in SCOTTY's core

  efforts to control costs that included the moving of the corporate
  headquarters to Pittsburgh as well as modest revenue growth (as revenues
  topped $100 million for the first time in a number of years). The stock is
  selling at less than 4 times our fiscal (March) 1998 cash flow, which is the
  least expensive amongst its peers. We remain concerned about the challenging
  industry environment, thus our Market Performance rating. Several of the
  operational and financial highlights included:

    .  Cost efficiencies that management estimated to be $1.5 million
       sequentially that offset the margin pressure in the core operations.
       Besides the headquarters relocation, which translated to a $400,000
       savings in the quarter, productivity improved, as labor utilization
       increased from 70% to 73%.

    .  An expanding backlog to $1.2 billion, a $47 million sequential increase
       despite the increased level of revenues. Of the $150 million of new
       business booked in the quarter, the most significant award was a $100
       million Air Force Remedial Action Contract. Furthermore, in October,
       SCOTTY was awarded an additional $180 million that included a $122
       million contract for remedial action at the Fernald DOE site in Ohio.

    .  The purchase of the Pacific Environment Group, a small niche company
       providing services to major oil companies on the West Coast, highlights
       management's efforts to date on the acquisition front. However,
       management reaffirmed its goal of having $1 billion in revenues within
       the next two years, compared with its current $400 million run-rate,
       implying that larger acquisitions will play an important part towards
       growth.

    .  Balance sheet management remains key as DSO's (excluding about 10% of
       receivables that are subject to dispute) are of 85 days. Cash balance of
       $62 million offset all of SCOTTY's debt.

 .  DONALDSON, LUFKIN & JENRETTE (9/25/97) -- Over the past several weeks SCOTTY
   has been awarded several projects both domestically and abroad and furthered
   its acquisition program, highlighting the Company's efforts to leverage its
   existing capabilities within the hazardous waste market along with
   management's efforts to broaden its capabilities. These efforts to diversify
   through acquisitions and joint ventures seek to leverage and expand the
   Company's core competencies to lessen SCOTTY's dependence on federal
   government spending. Nonetheless, SCOTTY remains a valued contractor to
   various federal government agencies. And while the federal cleanup market has
   been somewhat inconsistent over the past several years, SCOTTY's existing
   contracts and new contracts should provide the Company with a base load of
   work as management pursues its growth strategy.
