    On September 9, 1996, 3D Systems, Inc., an indirect wholly-owned subsidiary
    of the Company, purchased substantially all of the assets and business
    operations of Keltool, Inc. ("Keltool"), of St. Paul, Minnesota, a Company
    which produces steel tooling for plastic injection molding machines based
    on a patented process using sintered powdered steel.  Acquired in-process
    technology valued at $430,000 was expensed immediately.  The purchase price
    paid by the Company included $1,740,000 payable in cash (of which $875,000
    was paid on September 9, 1996 and $865,000 paid on October 10, 1996), the
    assumption of certain liabilities ($13,000) and the value of warrants to
    purchase 50,000 shares at an exercise price of $14.75 per share ($193,000). 
    The warrants were issued at fair market value and expire on September 9,
    1999.

    The allocation of the purchase consideration for Keltool are as follows:

         Trade receivables                              $   72,000

         Intangible assets                                 893,000
                                                        ----------
                                                        $1,946,000
                                                        ----------
                                                        ----------

    The results of operations relating to Keltool from September 9, 1996
    through September 27, 1996 are included with those of the Company and were
    not significant.

             Management's Discussion and Analysis of Financial Condition
                        and Results of Operations (Continued)

THREE MONTH PERIOD ENDED SEPTEMBER 27, 1996 COMPARED TO THE THREE MONTH 
PERIOD ENDED SEPTEMBER 29, 1995.

SALES.  Sales during the three month period ended September 27, 1996 (the 
"third quarter of 1996") were $19.8 million, an increase of 27% over the 
$15.6 million recorded during the three month period ended September 29, 1995 
(the "third quarter of 1995").

Product sales during the third quarter of 1996 increased $1.5 million or 13% 
to $12.6 million compared to $11.1 million during the third quarter of 1995. 
The increase was primarily the result of increased shipments of SLAs in 
Europe, which management believes is the result of increased sales and 
marketing efforts in Europe. The Company sold a total of  34 SLA systems in 
the third quarter of 1996, comprised of  1 SLA-190,  9 SLA-250's, 15 
SLA-350's (the Company's newest SLA system which features the new Zephyr-TM- 
recoater, a solid state laser and an automatic resin re-filling system) and 9 
SLA-500's (the Company's largest and highest priced system). During the third 
quarter of 1995, the Company sold 32 SLAs, comprised of 2 SLA-190's, 14 
SLA-250's and 16 SLA-500's. Orders for the Company's SLA systems 
significantly declined (in both the U.S. and Europe) in the third quarter of 
1996 compared to the third quarter of 1995, and SLA systems backlog at the 
end of the third quarter of 1996 was lower than the end of the third quarter 
of 1995.  

The Company believes that the decline in the U.S. orders in the third quarter 
of 1996 (when compared to the third quarter of 1995) was due primarily to the 
performance, and termination , of a number of the Company's independent 
domestic sales representatives ("agents"), and, to a lesser extent, to 
competitive pressures.  The Company's domestic marketing strategy has focused 
on a strong internal sales organization, as well as the utilization of agents 
(primarily, independent sales representatives in the machine tools industry). 
Because of a reduction in the performance of these agents, in August 1996, 
the Company determined to significantly reduce its use of these agents, and 
terminated its arrangements with all of them. Concurrently, the Company began 
actively to recruit additional personnel to bolster its internal sales and 
support organization.  The Company currently plans to complete its recruiting 
efforts during the fourth quarter of 1996, and has offered its agents the 
opportunity to enter into new arrangements with the Company, at lower 
commission rates than under their prior agreements with the Company. Because 
of the long cycle for SLA systems sales, the Company does not anticipate that 
the additions to its internal sales organization will significantly increase 
domestic sales in the fourth quarter of 1996.  While historically there has 
not always been a good correlation between orders and ending backlog in one 
quarter and revenues in the following quarter, the decline in U.S. orders in 
the third quarter of 1996, coupled with potential inefficiencies caused by 
the recent changes in the Company's domestic sales organization, could 
negatively impact domestic revenues in the fourth quarter of 1996.   The 
Company anticipates that European orders should increase in the fourth 
quarter of 1996 as compared to the third quarter of 1996.

The Company believes that SLA system sales may also fluctuate on a quarterly 
basis as a result of a number of other factors, including the status of world 
economic conditions, fluctuations in foreign currency exchange rates and the 
timing of product shipments (the U.S. list price of an SLA-500, for example, 
exceeds $400,000; thus the acceleration or delay of a small number of 
shipments from one quarter to another can significantly affect the results of 
operations for the quarters involved). Other factors which may impact 
quarterly sales include the introduction in 1996 of one new product, the 
SLA-350 Series 10, a new, advanced SLA system and the announcement of 
another, the low-priced Actua 2100 office modeler (which uses a technology 
completely different from stereolithography), designed for operation in 
engineering and design offices. During May, the Company began commercial 
shipments of the SLA-350.  The Company is presently continuing its 
development efforts in connection with the Actua 2100 and shipments of the 
Actua will be delayed until certain technical issues have been resolved.  
While shipments are currently scheduled to commence prior to the end to the 
current fiscal year, the possibility exists that first shipments may be 
further delayed.  The possibility exists that the announcement and 
introduction of these new products may have caused, and may cause in the 
future, potential customers of the Company who were considering the purchase 
of one of the Company's current models to defer their purchase decision until 
further information is available as to the performance and reliability of the 
new

products.  Further delays in shipments of new products may also occur as a 
result of unexpected problems encountered in actual use.   In addition, the 
Company relocated its manufacturing operations from Valencia, California to 
Grand Junction, Colorado during the third quarter of 1996.  If the Company 
experiences problems in connection with this relocation (including 
difficulties in the timely hiring and training of new employees), shipment of 
certain of the Company's products may be delayed.

Service sales during the third quarter of 1996 increased $2.7 million, or 
60%, compared to the third quarter of 1995, primarily as a result of 
increased maintenance revenues due to the larger installed base of SLA 
systems in the U.S. and Europe as well as from greater sales (approximately 
$625,000) of SLA upgrades (primarily Zephyr upgrades) to existing SLA 
customers. The Company anticipates that sales of Zephyr upgrades in future 
quarters should be lower than the amount recorded in the third quarter of 
1996. 
                                           
COST OF SALES.  Cost of sales increased to $10.3 million or 52% of sales in 
the third quarter of 1996 from $8.0 million or 51% of sales in the third 
quarter of 1995.
                                           
Product cost of sales as a percentage of product sales increased to 47% 
during the third quarter of 1996 compared to 45% during the third quarter of 
1995.  The increase in 1996 was primarily the result of the stronger dollar 
in the third quarter of 1996, as compared to the third quarter of 1995; 
greater discounting of European SLA system sales in 1996 due to competition; 
and increased manufacturing expenses as a result of certain inefficiences 
caused by the transition of the Company's  manufacturing activities from 
Valencia, California to its new manufacturing facility in Grand Junction, 
Colorado. These factors were partially offset by lower commission payments to 
domestic agents as a result of fewer domestic sales of SLAs during the third 
quarter of 1996, as compared to the third quarter of 1995, and by the  
termination of the agent relationships described above. The Company's gross 
profit margins on product sales are affected by several factors including, 
among others, sales mix, distribution channels and fluctuations in foreign 
currency exchange rates and, therefore, may vary in future periods from those 
experienced during the third quarter of 1996. Additionally, the Company 
anticipates that the gross margins related to the Actua 2100 system  (which 
are not currently expected to constitute a material portion of the Company's 
sales in the current fiscal year) will be lower than margins on its SLA 
systems, and, if revenues from the sales of Actua 2100 represent a material 
portion of the Company's product sales, gross margins from product sales 
would be reduced.  The Company also anticipates that gross margins related to 
the Actua 2100 will be lower during the initial phases of production as a 
result of certain inefficiencies and anticipates, in the event of increased 
production, that Actua 2100 gross margins could increase as a result of lower 
per unit material costs (due to greater purchasing economies) and increased 
manufacturing efficiencies.

Service cost of sales as a percentage of service sales decreased to 61% 
during the third quarter of 1996 compared to 65% during the third quarter of 
1995, primarily as a result of the more profitable Zephyr upgrades delivered 
in 1996 compared to those upgrades offered in the third quarter of 1995.  The 
improved margins from field service operations were partially offset, 
however, by lower margins from the Company's U.S. Technology Center due to 
the Technology Center's testing of both new hardware and software products as 
well as the increased use of outside vendors for certain rapid prototyping 
applications in 1996.

SELLING, GENERAL AND ADMINISTRATIVE EXPENSES.  Selling, general and 
administrative ("S,G&A") expenses increased $1.3 million or  27 % in the 
third quarter of 1996 compared to the third quarter of 1995, primarily as a 
result of expanded sales and marketing programs in both Europe and the U.S.  
The Company currently anticipates that S,G&A expenses for the fourth quarter 
of 1996 will be slightly higher than the third quarter of 1996 due primarily 
to the expansion of the Company's U.S. direct sales distribution channel.  
The Company currently anticipates that if its revenues continue to grow, 
S,G&A expenses as a percentage of total sales in future quarters should begin 
to decline, primarily as a result of economies of scale.  However, these are 
forward looking statements and as with other such statements are subject to 
uncertainties.  For example, if sales do not continue to grow over the 
period, it is less likely that S,G&A expenses as a percentage of total sales 
would decline.

                        and Results of Operations (Continued)


RESEARCH AND DEVELOPMENT EXPENSES.  Research and development ("R&D") expenses 
during the third quarter of 1996 increased approximately $816,000 or 58% 
compared to the third quarter of 1995. The increase in R&D expenses in 1996 
was primarily the result of the write-off during the third quarter of 1996 of 
acquired in-process technology valued at $430,000 in connection with the 
Keltool acquistion (see Note 4 of Notes to Consolidated Financial Statements) 
as well as the Company's efforts towards the development of the Actua 
2100 and certain other development projects. Based on the Company's 
historical expenditures related to research and development and its current 
development goals, the Company anticipates for the foreseeable future, 
research and development expenses will be equal to approximately ten percent 
of sales.  However, this is a forward-looking statements and, as with any 
such statement , is subject to uncertainties.  For example, if total sales of 
the Company for any particular period do not meet the anticipated sales of 
the Company for that period, research and development expenses as a 
percentage of sales may exceed 10%.

OPERATING INCOME.  Operating income for the third quarter of 1996 was 6.1% of 
total sales compared to 9.3% of total sales in the third quarter of 1995.  
The decrease in the percentage of operating income to total sales in 1996 was 
primarily attributable to the increases in product cost of sales and R&D 
expenses in 1996, as described above.

OTHER INCOME AND EXPENSES.  Interest income decreased to $361,794 during the 
third quarter of 1996 from $541,392 during the third quarter of 1995, 
primarily as a result of the lower investment balances due to cash used for 
operating activities in 1996.

Interest expense increased to $34,753 during the third quarter of 1996 from 
$7,989 in the third quarter of 1995 primarily as a result of the Company's 
financing of its Colorado facilty which was effected August 20, 1996 (see 
Note 5 of Notes to Consolidated Financial Statements).

PROVISION FOR INCOME TAXES (BENEFITS).  For the third quarter of 1996, the 
Company's tax expense was $510,661 or 33% of pre-tax income, compared to a 
tax benefit of $2.9 million for the third quarter of 1995, which included a 
deferred tax benefit resulting from the recognition of deferred tax assets of 
$3.0 million (related primarily to net operating loss carryforwards 
attributable to the Company's domestic operations).

NINE MONTH PERIOD ENDED SEPTEMBER 27, 1996 COMPARED TO THE NINE MONTH PERIOD 
ENDED SEPTEMBER 29, 1995.

SALES.  Sales during the nine month period ended September 27, 1996 (the 
"first nine months of 1996") were $57.5 million, an increase of  31% 
over the $43.9 million recorded during the nine month period ended September 
29, 1995 (the "first nine months of 1995").

Product sales during the first nine months of 1996 increased $8.3 million to 
$38.2 million, compared to $29.9 million during the first nine months of 
1995, an increase of  28%.  The increase was primarily the result of 
increased shipments of SLA systems in both the U.S. and Europe, which 
management believes is the result of increased acceptance by industry of 
rapid prototyping equipment and technology as well as increased sales and 
marketing efforts in Europe. The Company sold a total of  107 SLA systems in 
the first nine months of 1996 which were comprised of  5 SLA-190's, 38   
SLA-250's, 25 SLA-350's and 39 SLA-500's. During the first nine months of 
1995, the Company sold 84 SLAs which were comprised of 3 SLA-190's, 46 
SLA-250's and 35 SLA-500's.

Service sales during the first nine months of 1996 increased $5.4 million or 
38% compared to the first nine months of 1995, primarily as a result of 
increased maintenance revenues due to the larger installed base of SLA 
systems in the U.S. and Europe.

COST OF SALES.  Cost of sales increased to $29.5 million or 51% of sales in 
the first nine months of 1996 from $21.9 million or 50% in the first nine 
months of 1995.  

Product cost of sales as a percentage of product sales increased to 46% 
during the first nine months of 1996 compared to 44% during the 
first nine months of 1995.  The increase in 1996 was primarily the result of 
an increase in commission payments to independent sales agents in 1996, as 
compared to the first nine months of 1995 (see discussion above), as well as 
the stronger U.S. dollar in the first nine months of 1996, as compared to the 
first nine months of 1995. This increase was partially offset, however, by 
the increase in SLA system sales during the first nine months of 1996. Profit 
margins on SLA systems and related software are typically greater than 
margins achieved on other product sales (related hardware, parts and 
polymers).

Service cost of sales as a percentage of service sales was 62% for both the 
first nine months of 1996 and 1995. Although service margins were equal, the 
Company did experience improved field service margins which was due to the 
more profitable Zephyr upgrades delivered in 1996 compared to those upgrades 
offered in 1995. The improved margins from field service operations were 
completely offset, however, by lower margins from the Company's U.S. 
Technology Center as a result of the Technology Center's testing of both new 
hardware and software products and the increased use of outside vendors for 
certain rapid prototyping applications in 1996.

SELLING, GENERAL AND ADMINISTRATIVE EXPENSES.  S,G&A expenses for the first 
nine months of 1996 were  32% of sales compared to 31% in the first nine 
months of 1995.  S,G&A expenses increased $5.0 million or 37% in 1996 
compared to  the first nine months of 1995, primarily as a result of expanded 
sales and marketing programs in both the U.S. and Europe.

RESEARCH AND DEVELOPMENT EXPENSES.  R&D expenses during the first nine months 
of 1996 increased approximately $1.6 million or 38% compared to the first 
nine months of 1995.  The increase in R&D expenses in 1996 was primarily the 
result of the Company's efforts towards the development of the Actua 2100, 
the SLA-350 and certain other development projects as well as the write-off 
during the third quarter of 1996 of acquired in-process technology valued at 
$430,000 in connection with the Keltool acquisition.

OPERATING INCOME.  Operating income for the first nine months of 1996 was 
6.2% of total sales compared to 9.6% of total sales in the first nine months 
of 1995. The decrease in the percentage of operating income to total sales in 
1996 was

              Management's Discussion and Analysis of Financial Condition

primarily attributable to the lower product gross margins in 1996, increased 
S,G&A expenses in 1996 and increased  R&D expenses in 1996, as described 
above.

OTHER INCOME AND EXPENSES.  Interest income increased to $1.2 million during 
the first nine months of 1996 compared to $724,490 during the first nine 
months of 1995, primarily as a result of the investment of funds from the 
Company's stock offering which was completed in June 1995.

Interest expense increased to $46,251 during the first nine months of 1996 
from $35,275 in the first nine months of 1995 primarily as a result of the 
Company's financing of its Colorado facility which was effected August 20, 
1996.

PROVISION FOR INCOME TAXES.  For the first nine months of 1996, the Company's 
tax rate was 38% of pre-tax income compared to a tax benefit of $2.7 million 
for the first nine months of 1995. During  the third quarter of 1995, the 
Company realized a net income tax benefit of $2.9 million which included a 
deferred tax benefit resulting from the recognition of deferred tax assets of 
$3.0 million (related primarily to net operating loss carryforwards 
attributable to the Company's domestic operations).

- -----------------------------
(1) Includes $766,000 and $722,000 of restricted cash at December 31, 1995 
and September 27, 1996, respectively.

Net cash used for operating activities during the first nine months of 1996 
was $5.7 million.  The negative cash flow from operations during the first 
nine months  of 1996, comprised primarily of an increase in inventory ($5.1 
million) as a result of a higher level of production and build-up of 
inventory components to facilitate the move of manufacturing operations to 
Colorado, an increase in accounts receivable ($3.6 million) as a result of 
the increase in sales during the third quarter of 1996 and a decrease in 
accounts payable ($2.4 million), was partially offset by net income ($2.9 
million), non cash depreciation and amortization ($2.5 million), and a 
decrease in deferred tax assets ($1.6 million).

Net cash used for investing activities during the first nine months of 1996 
totaled $8.2 million and was primarily the result of construction 
expenditures related to the Company's Grand Junction, Colorado facility ($3.9 
million), SLA equipment manufactured for use as demonstration equipment ($1.1 
million), and the purchase of computers and manufacturing equipment due to an 
increase in personnel and increased production capacity.

Net cash provided by financing activities during the first nine months of 
1996 was the result of the Company's financing of its Colorado facility 
through the issuance of $4.9 million in tax-exempt industrial revenue 
development bonds and by the exercise of stock options by employees. 

In July 1996, the Company extended its credit facility with Silicon Valley 
Bank ("SVB") (the "Credit Facility").  Under the terms of the agreement, 
which remains in effect through July 5, 1997, the Company can borrow from SVB 
up to $4,000,000, at prime.  The Credit Facility, which is unsecured, 
contains certain financial covenants including the maintenance of certain 
financial ratios, working capital, tangible net worth as well as covenants 
limiting mergers, acquisitions, recapitalizations, dividends, loans to 
others, and hypothecation of assets or corporate guarantees.  Since inception 
of the Credit Facility (June 1993) and at all times through September 27, 
1996, the Company has not utilized the facility.

The Company believes that funds generated from operations, existing working 
capital and its current line of credit will be sufficient to satisfy its 
anticipated operating requirements for at least the next twelve months.

not carried or reflected on the books and records of Seller (the "Purchased
Assets"), including without limitation, as shall exist at the date hereof, the

    3.   PURCHASE PRICE.  The Purchased Assets shall be purchased by Buyer from
Seller for a purchase price consisting of:

         (a)  $1,737,000, payable as follows:

              (i)  a fixed amount of $875,000 to Seller on the Closing Date by
wire transfer, and

              (ii) an amount equal to $862,000, subject to adjustment as set
forth in Section 4 hereof, to Seller on the last to occur of (a) expiration of
30 days after the Closing Date, or (b) resolution of any dispute as to the
amount of any adjustment required pursuant to Section 4 below, by wire transfer;

         (b)  the assumption of only those current liabilities of Seller set

pursuant to the Warrant Agreement (collectively, the "Purchase Price").

    The Purchase Price shall be allocated among the Purchased Assets as set 
forth in SCHEDULE 3(c) to this Agreement, and such allocation shall be used 
for federal and state tax purposes; provided, however, that Buyer may modify 
and amend the allocation set forth on SCHEDULE 3(c) prior to the Closing.  
With respect to the allocation of the purchase price to the noncompetition 
covenant of Duescher as set forth in the Non-Competition Agreement, in the 
event such allocation causes Duescher to incur an amount of combined federal 
and state income taxes higher than he would incur if there were no such 
allocation of the Purchase Price to the Non-Competition Agreement, Buyer 
shall reimburse Duescher such premium over Duescher's resulting tax liability 
as if there had been no such allocation.  In addition, in the event Buyer 
allocates a portion of the Purchase Price to any purchased depreciable 
equipment which results in the recapture of such depreciation, Seller shall 
reimburse Duescher such amount as is necessary to make Duescher "tax 
neutral," i.e., Seller shall reimburse Duescher the incremental increase in 
combined federal and state tax liabilities due to such recapture (at ordinary 
income tax rates) over the combined federal and state income tax liabilities 
Duescher would incur if an allocation causing such recapture were not made 
(at capital gains tax rates).

    4.   ADJUSTMENT TO PURCHASE PRICE.  

         (a) ADJUSTMENT BASED ON ADJUSTED BOOK VALUE OF PURCHASED ASSETS.  
The Second Payment shall be adjusted based upon the Adjusted Book Value of 
the Purchased Assets listed on the Asset List as of the Closing Date, as 
follows: (i) if the Adjusted Book Value of the Purchased Assets as of the 
Closing Date is less than $243,000, then the Second Payment shall be 
decreased by the amount by which the Adjusted Book Value is less than 
$243,000, and (ii) if the Adjusted Book Value of the Purchased Assets as of 
such date is greater than $243,000, the Second Payment shall be increased by 
the amount by which the Adjusted Book Value of the Purchased Assets as of the 
Closing Date exceeds $243,000.

         (b) PROCEDURES FOR ADJUSTMENTS TO THE SECOND PAYMENT.  The Purchase 
Price shall be adjusted as follows (the "Adjusted Purchase Price"):  Attached 
hereto as SCHEDULE 4(b) is the Asset List.  Not later than five (5) days 
following the Closing Date, Seller shall deliver to Buyer (i) the Closing 
Asset List, and (ii) the Closing Deduction List.  The parties hereto hereby 
covenant and agree that no adjustment shall be made to the Purchase Price in 
respect of the Closing Asset List unless (i) the value of the assets as set 
forth on the Asset List is greater than the value of the assets set forth on 
the Closing Asset List by an amount of $5,000 or more, or (ii) the value of 
the assets as set forth on the Asset List is less than the value of the 
assets set forth on the Closing Asset List by an amount of $5,000 or more, in 
which case the Purchase Price shall be reduced or increased, as the case may 
be, on a dollar-for-dollar basis in an amount equal to the entire difference. 
 Each of the Asset List, the Closing Asset List and the Closing Deduction 
List shall be prepared by Seller from Seller's books and records, consistent 
with Seller's past accounting practices consistently applied, and, so 
prepared, shall be presumptively valid unless Buyer shall give written notice 
to Seller of any disagreement or disagreements with the Closing Asset List or 
the Closing Deduction List within ten (10) days following its receipt of the 
Closing Asset List and Closing Deduction List, specifying in reasonable 
detail the nature and extent of such disagreement.

         (c) MANNER OF AJUSTMENTS.  The Second Payment shall be reduced to 
reflect customer deposits made to Seller for orders which have not been 
delivered by the Seller prior to the Closing.  In addition, it is 
acknowledged and agreed that (1) with respect to production and office 
equipment, the value of such assets in the Closing Asset List shall be 
determined by adding to the value of such assets on the Asset List the cost 
of any acquisitions between June 30, 1996 and the Closing Date and 
subtracting from the value of the Assets on the Asset List depreciation at a 
monthly rate of $1,800 and $114 for production and office equipment, 
respectively, and (2) with respect to inventory, the value of such asset on 
the Closing Asset List shall be determined by adding acquisitions to 
inventory and subtracting cost of sales from the value of the inventory on 
the Asset List, and (3) with respect to accounts receivable and prepaid 
expenses, the value on the Closing Asset List shall be the value of such 
assets on the Closing Date.

<PAGE>

         (d) DISAGREEMENT OVER ADJUSTED PURCHASE PRICE.  If Seller and Buyer 
are unable to resolve any disagreement with respect to the Closing Asset List 
which would result in an adjustment to the Purchase Price or with respect to 
the Closing Deduction List within five (5) days following receipt by Seller 
of the notice referred to in Section 4(b) above, the disagreement shall be 
submitted for resolution to Coopers & Lybrand LLP (the "Evaluator"); 
provided, however, that all undisputed amounts will be paid within two (2) 
business days after that portion of the adjustment to the Second Payment is 
determined hereunder.  The Evaluator shall act as an arbitrator to determine 
and resolve such disputes, based solely on presentations by Buyer and Seller 
and not by independent review. The Evaluator's resolution shall be made 
within fifteen (15) business days of the submission of the dispute, shall be 
in accordance with this Agreement, shall be set forth in a written statement 
delivered to Seller and Buyer and shall be final, binding and conclusive.  
Seller and Buyer shall each pay one half of all fees, costs and expenses of 
the Evaluator incurred in connection with the resolution of any dispute.

    5.   THE CLOSING.  The Closing shall take place on the Closing Date and may
be effected by means of facsimile transmissions (with same day delivery of
executed counterparts among all parties) and wire transfer of the Purchase Price
and shall, unless otherwise agreed to by the parties hereto, take place on
September 9, 1996.  If all conditions to the Closing have not been satisfied or
waived on or prior to September 9, 1996, the Closing shall take place on that
date which is five business days following the date on which all conditions to
the Closing have been satisfied or waived.  In the event the Closing does not
occur on or prior to October 15, 1996 (the "Drop Dead Date"), the parties'
rights and duties with respect to the transaction contemplated in this Agreement
and the other Agreements shall cease.

    6.   NO ASSUMPTION OF LIABILITIES.

         (a)  LIABILITIES NOT ASSUMED.  Buyer shall not and does not assume 
any liabilities, obligations or commitments of Seller of any kind, known or 
unknown, contingent or otherwise, of whatsoever kind or nature, other than 
those Assumed Liabilities specifically identified on SCHEDULE 3(b) hereto, 
which Schedule shall include only (a) the obligation of Seller under the 
License Agreement to pay royalties to 3M (as to which Seller is responsible 
for all obligations incurred by Seller prior to Closing); (b) the obligation 
to pay 3M the balloon payment in the amount of Eleven Thousand Seven Hundred 
Seventy-Nine Dollars and Seventy-Nine cents ($11,779.79) on January 25, 1998; 
(c) the assumption of up to $1,000 for accrued sick leave and vacation 
payable to employees of Seller who Buyer may employ following the Closing; 
and (d) any open purchase and/or sales orders of Seller as set forth on 
SCHEDULE 3(b).  Any obligations or commitments of Seller not identified on 
SCHEDULE 3(b) shall remain the sole responsibility of Seller and Seller and 
Duescher will jointly and severally indemnify and hold Buyer, its officers, 
directors and shareholders, and each of them, harmless from and against any 
and all such liabilities, expenses or obligations, including, but not limited 
to, (i) deferred expenses, trade account liabilities and capitalized lease; 
(ii) product liability claims; (iii) liabilities in respect of salaries, 
employee benefit plans, including obligations to employees for bonus and/or

payments upon the sale of the Purchased Assets; (iv) income, sales, transfer 
or other taxes, including taxes arising out of the transactions contemplated 
by this Agreement; (v) any claims related to environmental matters; or (vi) 
legal expenses or other transaction costs associated with the transactions 
contemplated by this Agreement.  Buyer may offer to hire, on its customary 
basis, any or all of the Employees (defined herein), but Buyer shall not 
assume or be bound by any of Seller's employment contracts or other 
obligations with respect to such Employees.  Buyer shall have no obligation 
whatsoever to hire or otherwise employ any or all of the Employees.

         (b)  CLAIMS BROUGHT AGAINST BUYER.  From and after the Closing Date,
Buyer shall notify Seller promptly of any claim made upon Buyer with respect to
any liabilities, obligations or commitments of Seller and Buyer shall have no
obligation to make any payment of, settle or offer to settle, or otherwise
satisfy such claim. 

    7.   REPRESENTATIONS AND WARRANTIES OF SELLER AND DUESCHER.  As a material
inducement to Buyer to enter into this Agreement and the Other Agreements to
which it is a party, and to perform its obligations hereunder and thereunder,
Seller and Duescher jointly and severally represent, warrant, and covenant to

date of this Agreement.

         (b)  AUTHORIZATION OF SELLER AND DUESCHER.  Seller has all requisite 
corporate power and authority to enter into and carry out the terms and 
conditions of this Agreement and the Other Agreements to which it is a party 
and all the transactions contemplated hereunder and thereunder.  All 
proceedings have been taken and all authorizations have been secured which 
are necessary to authorize the execution, delivery and performance by Seller 
of this Agreement and each of the Other Agreements to be executed by Seller.  
Duescher has the legal capacity to enter into this Agreement and each Other 
Agreement to which Duescher is a party in any capacity.  This Agreement has 
been duly and validly executed and delivered by Seller and by Duescher and 
constitutes, and the Other Agreements to which Seller or Duescher is a party, 
when executed and delivered by them will constitute, the valid and binding 
obligations of Seller and Duescher, as the case may be, enforceable in 
accordance with their respective terms, except as enforceability may be 
limited by applicable bankruptcy, insolvency, reorganization, moratorium or 
similar laws relating to or affecting creditors' rights generally.

         (c)  TITLE TO THE PURCHASED ASSETS.  Seller has, and will transfer to
Buyer at the Closing, good and marketable title to all of the Purchased Assets,

                                       7
<PAGE>

other than those specifically described on SCHEDULE 7(c) hereto.  Seller and 
Duescher are not parties to, nor are any of the Purchased Assets bound by or 
subject to, any leases or other agreements or instruments except as may be 
referred to herein or set forth on SCHEDULE 7(c) to this Agreement.
    
         (d)  FINANCIAL STATEMENTS.  Seller has delivered to Buyer the 
Financial Statements.  The Financial Statements are true, complete and 
accurate in all material respects, present fairly the financial condition of 
Seller for the periods therein specified, and were prepared in accordance 
with GAAP consistently applied throughout the periods involved, subject to 
year-end adjustments which will not be materially adverse, and except that 
the unaudited financial statements may not contain all footnotes required by 
GAAP.  Except as set forth in the June 30, 1996 balance sheet of Seller 
included in the Financial Statements or on SCHEDULE 7(d), there are no 
liabilities, debts, claims or obligations, whether accrued, absolute, 
contingent or otherwise, whether due or to become due, which could materially 
and adversely affect the Purchased Assets or the rights of Seller therein and 
thereto.

         (e) ABSENCE OF CERTAIN CHANGES OR EVENTS.  Since the date of the June
30, 1996 balance sheet, there has not been any change in, or event affecting,
the business condition, properties, assets, liabilities, operations or prospects
of Seller's business other than changes in the ordinary course of its business,
none of which has (either when taken by itself or when taken in conjunction with
any other or all such other changes) been materially adverse to Seller's
business.  Except as set forth in SCHEDULE 7(e), since the date of the June 30,
1996 balance sheet, Seller's business has not suffered any adverse change in,
and no events have occurred which, individually or in the aggregate, have had,
or may have, any material adverse effect on, the financial condition, results of
operations, business or prospects of Seller's business other than as reflected
in the June 30, 1996 balance sheet and statements of income and expenses.

         (f)  EFFECT OF AGREEMENT.  The execution and delivery by each of
Seller and Duescher of this Agreement and the agreements referred to herein, the
sale by Seller of the Purchased Assets to Buyer, the performance by each of
Seller and Duescher of their respective obligations pursuant to the terms of
this Agreement and the Other Agreements, and the consummation of the
transactions contemplated hereby and under such Other Agreements, do not and
will not, with or without the giving of notice or lapse of time, or both:

           (i)     violate any judgment, order, writ or decree of any court of
administrative body applicable to Seller;

          (ii)     accelerate or constitute an event entitling the holder of
any indebtedness of Seller or Duescher to accelerate the maturity of such
indebtedness or to increase the rate of interest presently in effect with
respect to such indebtedness; or

                                       8

<PAGE>

         (iii)     result in the breach of (with the exception of the License 
Agreement), constitute a default under, constitute an event which with notice 
or lapse of time, or both, would become a default under, or result in the 
creation of any lien, security interest, charge or encumbrance upon any of 
the Purchased Assets or other properties of Seller or Duescher under any 
agreement, commitment, contract (written or oral) or other instrument to 
which Seller or Duescher is a party, or by which the Purchased Assets or 
other properties of Seller or Duescher are bound or affected.

         (g)  LITIGATION.  Except as set forth on SCHEDULE 7(g) to this 
Agreement, there is no claim, legal action, suit, arbitration, investigation 
or hearing of which Seller or Duescher has received notice, notice of claim 
or other legal, administrative or governmental proceedings pending or, to 
Seller's or Duescher's best knowledge, threatened against Seller or Duescher 
(or in which Seller is a plaintiff or otherwise a party thereto) relating to 
the Purchased Assets or the Keltool Process.

         (h)  ACCOUNTS RECEIVABLE.  The accounts receivable reflected in the 
1995 Financial Statements and subsequently arising arose from valid sales and 
transactions in the ordinary course of business and represent valid 
obligations due Seller, and have been collected or are collectible in the 
ordinary course of business consistent with past practice.  Within one year 
from the Closing, at Buyer's request and upon 30 days written demand, Seller 
agrees to purchase from Buyer all materially delinquent accounts receivable, 
defined as those accounts for which credit was extended by Seller prior to 
the Closing and are more than 180 days past due (applying any payment made by 
a debtor to such debtor's invoices on a first-in first out basis), and for 
which Buyer has made reasonable collection attempts from the debtor. 

         (i)  EMPLOYEES.  SCHEDULE 7(i) contains a true and complete list of 
all current employees (the "Employees") of Seller and all written or oral 
employment contracts and collective bargaining agreements and all other 
agreements or arrangements providing for employee compensation, to which 
Seller is a party or by which Seller is bound.  Seller is not delinquent in 
payments to any of its directors or employees or former directors or 
employees for any wages, salaries, commissions, bonuses or other direct 
compensation for any services performed by them or amounts required to be 
reimbursed to such directors or employees.  There are no labor disputes, 
troubles or controversies of any type or character between Seller and any of 
its Employees or former employees. 

         (j)  EMPLOYEE BENEFIT PLANS, ETC.  Except as set forth on SCHEDULE 
7(j), with respect to Employees or former employees of Seller, Seller does 
not maintain or contribute to any (i) nonqualified deferred compensation, 
bonus or retirement plans or arrangements, (ii) qualified defined 
contribution or defined benefit plans or arrangements which are employee 
pension benefit plans (as defined in Section 3(2) of ERISA, or (iii) employee 
welfare benefit plans, (as defined in Section 3(1) ERISA), or material fringe 
benefit plans or programs (the "Plans").  Seller does not and has not within 
the last five years contributed to any defined benefit plan (as defined in

                                       9

<PAGE>

Section 3(35) of ERISA) or multiemployer pension plan (as defined in Section 
3(37) of ERISA).  Seller does not maintain or contribute to any employee 
welfare benefit plan which provides health, accident or life insurance 
benefits to former employees, their spouses or dependents, other than in 
accordance with Section 4980B of the Internal Revenue Code of 1986, as 
amended. 

         (k)  CUSTOMERS AND SUPPLIERS.  SCHEDULE 7(k) contains a correct and
complete list of each of the 20 largest customers of Seller's business who have
purchased from the Seller goods and/or services during the twelve months prior
to the date hereof and indicates the dollar value of goods and/or services
purchased by, and the pricing to, each such customer.  SCHEDULE 7(k) also
contains a list of each of the 10 top suppliers of the Seller who have supplied
goods and/or services to Seller's business and indicates the dollar value and
pricing of the goods and/or services supplied by each such supplier during such
calendar year.  Except as set forth on SCHEDULE 7(k), to Seller's and Duescher's
best knowledge, no such customer or supplier, or any other person or entity
having material business dealings with the Seller, will or may cease to continue
such relationship with the Buyer, or will or may substantially reduce the extent
of such relationship, at any time from or after the Closing Date.  To the best
knowledge of the Seller and Duescher, (a) there is no other existing or
contemplated material modification or change in the business relationship of the
Seller with, nor (b) any existing condition or state of facts or circumstances,
which has materially affected adversely, or will materially adversely affect,
the relationship of Seller's business after it is acquired by Buyer with, the
Seller's customers or suppliers or which has prevented or will prevent such
business from being carried on by the Purchaser after the Closing in essentially
the same manner as it is currently carried on.

         (l)  ENVIRONMENTAL COMPLIANCE MATTERS.  Neither Seller nor Duescher 
has received any notice of any claim, proceeding or investigation under 
federal, state or local law relating to air, soil, subsurface and water 
pollution, soil monitoring and the storage, treatment, disposal, removal, 
remediation, release, discharge or emission or any Hazardous Material with 
respect to the Premises or the processes used in Seller's business.  To the 
best knowledge of Seller and Duescher, neither Seller nor any predecessor 
entity operating or controlling Seller's business, has ever owned, leased or 
operated or otherwise controlled any real property at which a claim or 
proceeding is presently pending or threatened, nor is there any condition on 
any such property which would give rise to any such claim or proceeding under 
federal, state or local law relating to air, soil, subsurface, water 
pollution, soil monitoring and the storage, treatment, disposal, removal, 
remediation, release, discharge or emission of any Hazardous Material.  To 
the best of Seller's knowledge, Seller has operated Seller's business in 
compliance with all federal, state and local laws relating to air, soil, 
subsurface and water pollution, soil monitoring and the storage, treatment, 
disposal, removal, remediation, release, discharge or emission or any 
Hazardous Material, and to the best knowledge of Seller and Duescher, there 
has been no release of Hazardous Material from the operation of Seller's 
business at the Premises or anywhere Seller has operated Seller's business.

                                       10

         (m) CONTRACTS.  The contracts listed in SCHEDULE 7(m) constitute all 
contracts, purchase orders, agreements, licenses, and other commitments and 
arrangements in effect as of the Closing Date that either (1) involve 
expenditure by Seller of more than $500 or (2) require performance by any 
party to the contract thereto more than six (6) months after the Closing 
Date.  All such contracts are valid, binding, and enforceable in accordance 
with their terms and are in full force and effect.  There are no existing 
defaults by Seller under any such contracts and no act, event, or omission 
has occurred that, whether with or without notice, lapse of time, or both, 
would constitute a default thereunder.

         (n) THIRD-PARTY INTERESTS IN PURCHASED ASSETS.  Seller has not
granted, transferred, or assigned any right or interest in the Purchased Assets
to any person or entity, except pursuant to the contracts identified in SCHEDULE
7(n).  There are no contracts, agreements, licenses, and other commitments and
arrangements in effect with respect to the marketing, distribution, licensing,
or promotion of the Keltool Process or the Purchased Assets, including the
Intellectual Property, by any independent salesperson, distributor, sublicensor,
or other remarketer or sales organization, except pursuant to the contracts
identified in SCHEDULE 7(n).

         (o)  CONDITION OF SELLER'S PURCHASED ASSETS.  The Purchased Assets
constitute all of the assets used in and required for the conduct of the
business of Seller, except for the Excluded Assets listed on SCHEDULE 2 attached
hereto.  All machinery and equipment included in the Purchased Assets is being
delivered "as is", except as to the eight working furnaces of Seller, which are,
and as of the Closing Date shall be, in good operating condition and repair
(with the exception of normal wear and tear) free from defects.  All inventory

of Seller's business has been and is being conducted in accordance with all
applicable laws, ordinances, rules and regulations, judgments and decrees of all
federal, state, county, municipal and local authorities applicable to Seller's
business.  No investigations by any governmental authorities asserting or
alleging any violation of or noncompliance with any such laws, ordinances, rules
and regulations, judgments and decrees are pending or, to the best knowledge of
Seller and Duescher, threatened.  To the best knowledge of Seller and Duescher,
SCHEDULE 7(p) sets forth a true and complete list of all federal, state, local

which is in full force and effect.  As of the date hereof, and during the 36
month period ending on the date hereof, no violation of any Permit shall have
occurred and no proceeding shall be pending or threatened to revoke or limit any
such Permit.  The Seller is not in breach of or in default under any
indebtedness or any mortgage, contract, lease or other agreement or commitment
relating to any of the Purchased Assets or to Seller's business.

         (q)  CONSENTS OR WAIVERS.  Seller has delivered to Buyer any and all 
consents or waivers of other parties required in order to permit the

A list of such consents and waivers is set forth on SCHEDULE 7(o) to this 
Agreement.

              (i)  TITLE TO INTELLECTUAL PROPERTY.  To Seller's and/or
Duescher's present knowledge, Seller owns, possesses, or has the right to use,

where necessary, has made timely and proper application for, any and all
Intellectual Property, and all governmental approvals, authorizations, consents,
licenses and permits necessary for the conduct of the business of Seller as
presently conducted where failure to file or apply, as applicable, would be

Immediately following the Closing, with the exception of the 3M Patents, to
Seller's and/or Duescher's present knowledge, Buyer shall own, possess, and have
the right to use, free and clear of all liens, claims and restrictions of any

Intellectual Property necessary or required for Buyer to operate the Purchased
Assets and use and exploit the Intellectual Property necessary or required for
Buyer to operate the Purchased Assets and use and exploit the Intellectual
Property and Keltool Process included therein where failure to file or apply, as

Seller as a whole.  With respect to the 3M Patents and modifying the foregoing,
immediately following the Closing, Buyer shall, to the present knowledge of
Seller and Duescher, own, possess, and have the right to use, free and clear of
all liens, claims and restrictions of any kind or nature (other than the
obligations of Buyer to pay royaltides un the License Agreement) and subject to
3M's rights pursuant to the License Agreement, have the right to bring actions
for infringement of, or where necessary, make application for, such 3M Patents. 
With respect to each service mark, trademark or trade name used by Seller,
Seller owns the goodwill identified by each such mark or name and has the
exclusive right to use all such marks and names in commerce.  SCHEDULE 7(s)(i)
sets forth all registered trademarks and service marks, all reserved trade
names, all registered copyrights, and all filed patent applications and issued
patents used in the Keltool process or otherwise necessary for the conduct of
Seller's business as now conducted.  Notwithstanding the foregoing, Seller and
Duescher are not making any representations that Seller's technology is
patentable.

inserts and EDM electrodes on which 3M holds the patents referred to in the 
License Agreement (the "3M Patents") in the United States, and has validly 
obtained a nonexclusive license from 3M to make, use and sell the intricately 
shaped parts.  Seller and Duescher know of no other agreements under which

right to license, to Seller with respect to the 3M Patents.

any inventions, developments or discoveries used in or necessary for the conduct
of Seller's business as now conducted.

              (vi) NO INFRINGEMENT.  Except as set forth on SCHEDULE 7(s)(vi)

mark, trade name, copyright, trade secret, proprietary right, process or other
Intellectual Property of any other person.  Neither Seller nor Duescher has
received any notice that any product designed and/or manufactured and/or
marketed or sold or proposed to be manufactured and/or marketed or sold by
Seller violates any license or infringes any patent, service mark, trademark,
trade name, know-how, proprietary process, formula, assumed name or copyright of
another and there is no pending or threatened claim or litigation against Seller
contesting the validity or right to use of any of the foregoing, nor has Seller
received any notice that any of said copyrights, trademarks, trade names,
franchises, certificates of public convenience and necessity, patent, patent
rights, licenses, permits, software, programs, proprietary rights or
Intellectual Property or the operation or proposed operation of the business of

              (vii) NO ROYALTIES.  Except under the License Agreement, no

processes or Intellectual Property.

              (viii) PERSONNEL AND THIRD PARTY AGREEMENTS.  All personnel,
including Employees and former employees, agents, consultants, and contractors,
who have contributed to or participated in the conception and development of the
Keltool Process or who have conceived, developed, invented, discovered, derived,
programmed or designed Intellectual Property on behalf of Seller either (1) have
been party to a "work-for-hire" arrangement or agreement with Seller, in
accordance with applicable federal and state law, that has accorded Seller full,
effective, exclusive, and original ownership of all tangible and intangible
property thereby arising, or (2) have executed appropriate instruments of
assignment in favor of Seller as assignee that have conveyed to Seller full,
effective, and exclusive ownership of all tangible and intangible property
thereby arising.  All personnel, including Employees and former employees,

the conception and development of the Keltool Process or Intellectual Property
on behalf of Seller, and all third parties who have knowledge of the trade
secrets, know-how, and technology with respect to the Keltool Process have

Insofar as Seller and Duescher know, there has been no material violation of any
such agreements by any person or entity.

Duescher in this Agreement or in any writing furnished or to be furnished

<PAGE>

and the representations and warranties contained in Paragraph 7(g) 
("Litigation") and Paragraph 7(s) ("Intellectual Property") shall survive the 
consummation of the transactions hereunder and any and all inspections,

parties to this Agreement, their successors and assigns, for a period of 
three years.

         (b)  INDEMNIFICATION BY SELLER.  Seller and Duescher hereby covenant 
and agree with Buyer, regardless of any investigation made at any time by or 
on behalf of Buyer or any information Buyer may have and regardless of the 
Closing of the purchase of the Purchased Assets hereunder, each of Seller and 
Duescher shall jointly and severally indemnify Buyer and its directors, 
officers, shareholders and affiliates, and each of their successors and 
assigns (individually, a "Buyer Indemnified Party") and hold them harmless 
from, against and in respect of any and all actual costs, losses, claims, 
liabilities, fines, or penalties (including interest which may be imposed in 
connection therewith and court costs and reasonable fees and disbursements of 
counsel):

              (i)  all liabilities of or claims against the Buyer Indemnified 
Parties of any nature, whether accrued, absolute, contingent or otherwise, 
arising out of the business of Seller or the Premises (whether known or 
unknown to Seller, the Buyer Indemnified Parties or any of them), to the 
extent arising out of the operation of the business of Seller or the Premises 
or incurred by Seller on or prior to the Closing Date;

              (ii) any breach of, or any inaccuracy in any of the 
representations, warranties, covenants or agreements made by Seller in this 
Agreement, any other agreement referred to herein, any Exhibit or Schedule to 
this Agreement or any certificate, instrument or writing delivered in 
connection therewith;

              (iii)     any attempt (whether or not successful) by any person
to cause or require a Buyer Indemnified Party to pay or discharge any debt,
obligation, liability or commitment of any of Seller or Duescher;

              (iv) any damages or out of pocket expenses incurred by Buyer from
an action by a third party successfully asserting (or alleging, but only where
Duescher has actual knowledge of any specific actual or threatened claim), that
the Intellectual Property, including without limitation, the Keltool Process
infringes a patent, copyright, trademark, service mark or any trade secret or
other intangible property right of a third party where such damage is due to the
breach of the representations made in Section 7(s) by the Seller or Duescher; or

                                       18

<PAGE>

              (v)  any action, suit, proceeding, compromise, settlement, 
assessment or judgment arising out of or incidental to any of the matters 
indemnified against in this Paragraph; provided, HOWEVER, that neither Seller 
nor Duescher shall be obligated to indemnify a Buyer Indemnified Party and 
hold it harmless under this Section 12(b) with respect to any settlement of a 
claim to which Seller has not consented, which consent shall not unreasonably 
be withheld.

Notwithstanding anything contained in Section 12(b) above to the contrary, a 
Buyer Indemnified Party shall not be entitled to assert any claim for 
indemnification contained in Section 12(b) unless and until such time as the 
claims of all Buyer Indemnified Parties, in the aggregate, pursuant to 
Section 12(b) exceed $25,000 (exclusive of all tax savings and insurance 
proceeds received) and at which time all claims of any one or more Buyer 
Indemnified Party for indemnification pursuant to Section 12(b) above may be 
asserted in full.  The remedies of Buyer set forth in this Section 12 are the 
exclusive remedies of Buyer and the Buyer Indemnified Parties under this 
Agreement, at law or in equity in the event of any breach of, or any 
inaccuracy in any of the representations, warranties, covenants or agreements 
made by Seller in this Agreement, any Exhibit or Schedule to this Agreement 
or any certificate, instrument or writing delivered in connection therewith; 
except, however, that in the event of an intentional breach, fraud, or 
reckless misrepresentation, Buyer's remedies against Seller shall not be 
limited by this provision and Buyer shall have all remedies against Seller 
available under applicable law.  It is expressly understood that any 
adjustment to the Second Payment pursuant to the provisions of Section 4(b) 
shall not constitute a claim of a Buyer Indemnified Party for purposes of 
this provision.

         (c)  INDEMNIFICATION BY BUYER.  Buyer hereby covenants and agrees 
with Seller that, regardless of any investigation made at any time by or on 
behalf of Seller or any information Seller may have and regardless of the 
consummation of the transactions hereunder, Buyer shall indemnify Seller and 
Duescher and Seller's directors, officers, shareholders and affiliates 
(individually, a "Seller Indemnified Party"), and hold them harmless from, 
against and in respect of any and all costs, losses, claims, liabilities, 
fines, penalties, damages and expenses (including interest which may be 
imposed in connection therewith and court costs and reasonable fees and 
disbursements of counsel) incurred by any of them in connection with:

              (i)  all liabilities of or claims against Seller Indemnified 
Parties of any nature, whether accrued, absolute, contingent or otherwise 
attributable to any event occurring after the Closing Date (whether known or 
unknown to Seller, or Buyer), relating to the operation by Buyer of the 
Purchased Assets from and after the Closing Date, except if (x) such 
liability results from or arises in connection with the breach of any of the 
representations, warranties, covenants or agreements made by Seller and/or 
Duescher in this Agreement, any other agreement referred to herein, any 
Schedule or Exhibit hereto or any certificate or instrument delivered in 
connection herewith or therewith, or (y) such liability is included under 
Section 12(b) above;

                                       19

<PAGE>

              (ii) any breach of, or any inaccuracy in any of the
representations, warranties, covenants or agreements made by Buyer in this
Agreement, any other agreement referred to herein, any Exhibit or Schedule
hereto or any certificate or instrument delivered in connection herewith or
therewith; 

              (iii) any attempt (whether or not successful) by any person to
cause or require a Seller Indemnified Party to pay or discharge any debt,
obligations, liability or commitment included in the Assumed Liabilities; or

              (iv) any action, suit, proceeding, compromise, settlement,
assessment or judgment arising out of or incidental to any of the matters
indemnified against in this Paragraph; provided, HOWEVER, that Buyer shall not
be obligated to indemnify a Seller Indemnified Party under this Paragraph with
respect to any settlement of a claim to which Buyer has not consented, which
consent shall not unreasonably be withheld.

         (d)  RIGHT TO DEFEND, ETC.  If the facts giving rise to any claim 
for indemnification hereunder shall involve any actual claim or demand by any 
third person against a Buyer Indemnified Party or a Seller Indemnified Party 
(who are referred to hereinafter as an "Indemnified Party"), the indemnifying 
party shall be entitled to notice of and entitled (without prejudice to the 
right of any Indemnified Party to participate at its own expense with counsel 
of its own choosing) to defend or prosecute such claim at its own expense and 
through counsel of its own choosing if it gives written notice of its 
intention to do so no later than the time by which the interests of the 
Indemnified Party would be materially prejudiced as a result of its failure 
to have received such notice; provided, however, that if the defendants in 
any action shall include both the indemnifying party and the Indemnified 
Party and the Indemnified Party shall have reasonably concluded that counsel 
selected by the indemnifying party has a conflict of interest because of the 
availability of different or additional defenses to the Indemnified Party, 
the Indemnified Party shall have the right to select separate counsel to 
participate in the defense of such action on its behalf, at the expense of 
the indemnifying party.  The Indemnified Party shall cooperate fully in the 
defense of such claim and shall make available to the indemnifying party 
pertinent information under its control relating thereto, but shall be 
entitled to be reimbursed, as provided in this Section 12, for all costs and 
expenses incurred by it in connection therewith.

    13.  POST-CLOSING COVENANTS. 

         (a) CONSULTING SERVICES.  Duescher hereby covenants and agrees to

as may be requested by Buyer with respect to the transfer of Seller's business,
the Purchased Assets, the Intellectual Property and the Keltool Process, for a
period of 30 days after the Closing Date, which period shall terminate earlier

acknowledges that Duescher will be performing services for Keltech and with 
respect to other business endeavors.

         (b) FURTHER ASSURANCES; RECORDS; AUDIT.  Each of the parties shall 
cooperate and take such actions, and execute all such further instruments and 
documents, at or subsequent to the Closing, as either may reasonably request 
in order to convey title to the Purchased Assets to Buyer, effect the 
assumption by Buyer of the Assumed Liabilities and to otherwise effectuate 
the terms and purposes of this Agreement.  Each party shall provide the other 
party or parties with access to all relevant documents and other information 
pertaining to the Purchased Assets and Seller's business which are needed by 
such other party or parties for the purposes of preparing tax returns or 
responding to an audit by any governmental agency, to permit Buyer's auditors 
(at the expense of Buyer) to prepare audited financial statements of Seller 
and the Seller's business for the three year period ended June 30, 1996, or 
for any other reasonable purpose. Such access will be during normal business 
hours and not subject to time limitations.

         (c) CONFIDENTIALITY OBLIGATIONS.  Seller and Duescher hereby 
covenant and agree that any and all information which has been disclosed to 
Seller, its employees, consultants, agents and, if applicable, stockholders 
during the discussions and negotiations leading to the execution of this 
Agreement, and all information to be disclosed to Seller, its employees, 
consultants and agents and, if applicable, stockholders, during the period 
commencing on the date of execution of this Agreement through the Closing or 
termination of this Agreement, shall constitute confidential information and 
trade secrets of Buyer, and as such are secret, confidential and unique and 
constitute the exclusive trade secrets and property of such party.  Such 
information has been made known and available to Seller and its respective 
employees, consultants and agents strictly in connection with the negotiation 
and execution of this Agreement and the consummation of the transactions 
provided for herein.  Seller and Duescher hereby acknowledge and agree that 
any use or disclosure of any such confidential information or trade secrets, 
other than pursuant to this Agreement, would be wrongful and would cause 
irreparable injury to Buyer.  Accordingly, Seller and Duescher hereby 
expressly agree, for Seller and on behalf of Seller's stockholders and 
directors, if any, and its principal officers, managers, employees, agents, 
consultants and representatives, that they will not at any time prior to the 
Closing or at any time thereafter, use or disclose, other than in accordance 
with the terms and provisions of this Agreement, any of such confidential 
information or trade secrets including without limitation, all confidential 
information included in the Intellectual Property of Seller. Seller and 
Duescher acknowledge that, in the event of a violation of the terms and 
provisions of this SECTION 13(c), the remedies at law would not be adequate; 
and accordingly, in such event Buyer may proceed to protect and enforce its 
rights under this SECTION 13(c) by a suit in equity for specific performance 
hereof, or for an injunction against the violation hereof.

         (d)  APPLICATIONS AND ASSIGNMENTS.  At the request of Buyer, 
Duescher shall assist Buyer and shall cause employees of Seller to assist and 
cooperate with Buyer in applying for and obtaining both domestic and foreign 
patents, or copyrights, as the case may be, on all Intellectual Property 
devised, discovered, developed, invented or authored by Duescher or any other 
employee of Seller prior to the Closing (or in which Duescher or such 
employees of Seller may otherwise obtain, or have otherwise obtained, any 
rights, while in the employ of the Seller) which relates to or was developed 
in connection with the Keltool Process or the business of Seller, that the 
Buyer deems to be patentable or copyrightable, and Duescher shall execute and 
shall cause all employees of Seller to execute at any time or times any and 
all documents and perform all acts reasonably requested by Buyer which Buyer 
deems to be necessary or desirable in order to obtain such patents or 
copyrights or otherwise to vest in Buyer full and exclusive title and 
interest in and to all such Intellectual Property, to protect the same 
against infringement by others and otherwise to aid the Buyer in connection 
with any continuations, renewals or reissues of any patents or copyrights, or 
in the conduct of any proceedings or litigation in regard thereto.  Buyer 
shall pay Duescher and the employees of Seller for their services in 
connection with the applications made pursuant to this Paragraph on an hourly 
basis, which hourly rate shall be agreed upon by the parties at that time and 
shall in all events be reasonable under the circumstances.  All filing fees 
and documentation expenses incurred in procuring any patent or copyright 
shall be born by the Buyer.

inquiries concerning the Purchased Assets and the purchased business to Buyer

Premises or to the Purchased Assets for any period ending on or prior to the 
Closing Date and Seller shall remain so liable for the payment of all of his 
taxes attributable to or relating to the consummation of the transactions 
contemplated herein, and shall indemnify and hold Buyer harmless from and 
against all liability in connection therewith.

         (b)  SALES TAXES.  It is understood that the consideration payable by
Buyer as specified herein does not include any applicable sales, use or other

similar taxes, if any, arising out of the consummation of the transactions
herein provided for and shall be liable for the filing of all necessary tax
returns and reports with respect to such taxes.

    15.  NONCOMPETITION.  Seller hereby agrees that Seller shall not for a 
period of five years from and after the Closing Date, directly or indirectly, 
and whether as a principal or

                                       22

agent or otherwise, or alone or in association with any individual or any 
other entity, carry on, be engaged or take part in, consult or advise, or 
own, share in the earnings of, or invest in the stock, bonds or other

percent (2%) of the total outstanding stock, bonds or other securities), any 
other entity which is engaged in a business which is in any other manner 
competitive with the business of Buyer, as conducted during the one year 
period prior to the date hereof (a "Competing Activity"); provided however,

conducted (the "Keltech Business").  It is agreed that the Keltech Business 
as currently conducted does not involve the manufacture of, sale of, or 
provision of services to enable or facilitate the manufacture or creation of, 
any hard tools or molds for hard tools.  Seller covenants and agrees to 
change the name of its corporation with the Secretary of State of the State 
of Minnesota, which new name shall not include the word "Keltool."

THE SECURITIES EVIDENCED BY THIS AGREEMENT HAVE NOT BEEN REGISTERED UNDER THE 
SECURITIES ACT OF 1933, AS AMENDED, HAVE BEEN TAKEN FOR INVESTMENT AND MAY 
NOT BE SOLD, TRANSFERRED, ASSIGNED, PLEDGED, HYPOTHECATED OR OTHERWISE 
DISPOSED OF EXCEPT IN ACCORDANCE WITH THE TERMS OF THIS AGREEMENT.            

                                WARRANT AGREEMENT


         This Warrant Agreement (the "Agreement") is made and entered into this
9th day of September, 1996 by and between 3D Systems Corporation, a Delaware
corporation (the "Company"), and Keltool, Inc., a Minnesota corporation (the
"Holder").

    In consideration of the premises and mutual covenants contained herein, the
Holder and the Company hereby agree as follows:

    1.   GRANT OF WARRANT.  In consideration of the sum of $100.00 and other
good and valuable consideration, the receipt and adequacy of which are hereby
acknowledged, the Company hereby grants to the Holder the right and option (the
"Warrant"), upon the terms and subject to the conditions set forth in this
Agreement, to purchase an aggregate of 50,000 shares of Common Stock, par value
$0.001 per share, (as from time to time adjusted pursuant to Section 4 below,
the "Shares") of the Company for $14.75 per share (the "Exercise Price").  The
number of Shares and the Exercise Price shall be subject to adjustment as set
forth in Section 4 hereof.

    2.   TERM OF WARRANT.   The Warrant shall terminate and expire at 5:00 p.m.
(Los Angeles Time) on September 9, 1999.

    3.   EXERCISE OF WARRANT.  There is no obligation to exercise all or any
portion of the Warrant.  The Warrant may be exercised, in whole or in minimum
increments of 10,000 Shares, at any time after the date hereof only by delivery
to the Company of:

         3.1  Written notice of exercise in form and substance identical to
Exhibit "A" attached to this Agreement; and

         3.2  Payment of the Exercise Price of the Shares being exercised (the
"Purchased Shares"), by (a) wire transfer in immediately available Federal
funds, or (b) in the manner set forth in Section 3.5 below.

         3.3  Upon receipt of the Exercise Price therefor, the Company shall
promptly issue in the name of the Holder a certificate evidencing the Purchased
Shares being purchased by such exercise and deliver such certificate to the
address requested in the notice of exercise.

<PAGE>

         3.4  No fractional shares or scrip representing fractional shares
shall be issued upon the exercise of this Warrant. In lieu of any fractional
share to which the Holder would otherwise be entitled, the Company shall make a
cash payment equal to the Exercise Price multiplied by such fraction.

         3.5  Notwithstanding any provisions herein to the contrary, if the
fair market value of one share of Common Stock is greater than the Exercise
Price (at the date of calculation as set forth below), in lieu of exercising
this Warrant for cash, the Holder may elect to receive shares equal to the value
(as determined below) of this Warrant (or the portion thereof being canceled) by
surrender of this Warrant at the principal office of the Company, together with
the properly endorsed Notice of Exercise and notice of such election, in which
event the Company shall issue to the Holder a number of shares of Common Stock
computed using the following formula:

              Y (A-B)
              -------
         X =     A

Where    X =  the number of shares of Common Stock to be issued to the Holder

         Y =  the number of shares of Common Stock purchasable under the
              Warrant or, if only a portion of the Warrant is being exercised,
              the portion of the Warrant being canceled (at the date of such
              calculation)

         A =  the fair market value of one share of the Company's Common Stock
              (at the date of such calculation)

         B =  Exercise Price (as adjusted to the date of such calculation)


    For purposes of the above calculation, fair market value of one share of
    Common Stock shall be determined by the Company's Board of Directors in
    good faith; provided, however, that where there exists a public market for
    the Company's Common Stock at the time of such exercise, the fair market
    value per share shall be the average of the closing bid and asked prices of
    the Common Stock quoted in the Over-The-Counter Market Summary or the last
    reported sale price of the Common Stock or the closing price quoted on the
    Nasdaq National Market or on any exchange on which the Common Stock is
    listed, whichever is applicable, as published in the Western Edition of The
    Wall Street Journal for the five (5) trading days prior to the date of
    determination of fair market value.

                                       2

    4.   REPRESENTATIONS, WARRANTIES AND COVENANTS OF HOLDER.  The Holder makes
the following representations, warranties and covenants:

         4.1  Holder is acquiring the Warrants for its own account with the
present intention of holding such securities for investment purposes only and
not with a view to, or for sale in connection with, any distribution of such
securities (other than a distribution in compliance with all applicable federal
and state securities laws).

         4.2  Holder is an experienced and sophisticated investor and has such
knowledge and experience in financial and business matters that it is capable of
evaluating the relative merits and the risks of an investment in the Warrants
and in the Shares and of protecting its own interests in connection with this
transaction.

         4.3  Holder is willing to bear and is capable of bearing the economic
risk of an investment in the Warrants and the Shares.  

         4.4  The Company has made available, prior to the date of this
Agreement, to Holder the opportunity to ask questions of the Company and its
officers, and to receive from the Company and its officers information
concerning the terms and conditions of the Warrants and this Agreement and to
obtain any additional information with respect to the Company, its business,
operations and prospects, as reasonably requested by the Holder.

         4.5  Holder is an "accredited investor" as that term is defined under
Rule 501(a)(8) of Regulation D promulgated by the Securities and Exchange
Commission under the Act.

         4.6  For purposes of the application of federal and state securities
laws, Holder acknowledges that the offer and sale of the Warrants to such Holder
occurred in the State of Minnesota and that Holder is a resident of the State of
Minnesota.

    5.   REPRESENTATIONS, WARRANTIES AND COVENANTS OF THE COMPANY. 

         5.1  The Company is a corporation duly organized, validly existing and
in good standing under the laws of the State of Delaware.  The Company has the
requisite corporate power and authority to carry on its business as now being
conducted and to execute, deliver and perform this Agreement and to consummate
the transactions contemplated hereby.

         5.2  All corporate action on the part of the Company, its directors
and shareholders necessary for the authorization, execution, delivery and
performance by the Company of this Agreement and the consummation of the
transactions contemplated hereby, has been taken.  This Agreement constitutes
the valid and binding obligation of the Company, enforceable in accordance with
its terms, subject to laws of general application relating to

                                       3

<PAGE>

bankruptcy, insolvency and the relief of debtors and rules of law governing
specific performance, injunctive relief or other equitable remedies.

         5.3  The execution and delivery of this Agreement by the Company does
not, and the consummation by the Company of the transactions contemplated by
this Agreement will not, constitute or result in a breach or violation of, or
(with or without the giving of notice or the lapse of time) a default under, 
(i) the Certificate of Incorporation or By-laws of the Company or (ii) any law 
to which the Company is subject.

         5.4  The Purchased Shares, when issued in accordance with the terms of
this Warrant, will be duly authorized, issued and nonassessable shares of the
Common Stock of the Company, free and clear of any liens, claims or restrictions
imposed by or through the Company other than as set forth in this Agreement.
 
         5.5  The Company covenants that it will at all times reserve and keep
available out of its authorized but unissued shares of Common Stock, solely for
the purpose of effecting the issuance of the Purchased Shares upon exercise of
all or part of the Warrants, such number of shares of Common Stock as shall then
be issuable upon the exercise of all of the Warrants.

         5.6  The Company covenants that the Company currently meets the
eligibility requirements for use of Form S-3 for transactions involving
secondary offerings.

    6.   RESTRICTIONS ON TRANSFER OR EXERCISE OF THE WARRANTS AND SHARES. 
Holder shall not sell, transfer (with or without consideration), assign, 
pledge, hypothecate or otherwise dispose of (collectively, "Transfer") any of 
the Purchased Shares unless the Purchased Shares are disposed of pursuant to 
and in conformity with an effective registration statement filed with the 
Securities and Exchange Commission (the "Commission") pursuant to the 
Securities Act of 1933, as amended (the "Act"), or pursuant to an available 
exemption from the registration and prospectus delivery requirements of the 
Act, and the proposed disposition will not result in a violation of the 
securities laws of any state of the United States.

    If requested by the Company, Holder shall, prior to the transfer of such 
Purchased Shares, deliver to the Company a written opinion of counsel, 
satisfactory to the Company and its counsel, that the proposed disposition 
will comply with the requirements set forth in this Section 6.

    Any attempted Transfer which is not in full compliance with this Section 6
shall be null and void AB INITIO, and of no force or effect.

    The Holder further agrees that any certificate evidencing the Purchased
Shares shall bear the following legend:

                                       4

<PAGE>

         THE SECURITIES EVIDENCED BY THIS CERTIFICATE HAVE NOT BEEN
         REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED,
         HAVE BEEN TAKEN FOR INVESTMENT, AND MAY NOT BE SOLD,
         TRANSFERRED, ASSIGNED, PLEDGED, HYPOTHECATED OR OTHERWISE
         DISPOSED OF EXCEPT IN ACCORDANCE WITH THE TERMS OF AN
         AGREEMENT BETWEEN THE COMPANY AND THE REGISTERED HOLDER
         HEREOF, A COPY OF WHICH AGREEMENT IS ON FILE AT THE
         PRINCIPAL OFFICES OF THE COMPANY.

    The Holder further acknowledges and agrees that the Company may, at its
option, place notations evidencing the foregoing restrictions on transfer in its
shareholders register, and may place appropriate "stop transfer" instructions
with its transfer agent, if any.

    7.   COVENANTS OF HOLDER AND THE COMPANY.

         7.1  DEMAND REGISTRATION.

              (a)  As soon as practical following receipt by the Company of a
written request executed by the Holder and requesting registration of the resale
by Holder of all of the Purchased Shares, the Company shall at its sole cost and
expense file a registration statement with the Commission on Form S-3 or any
successor form, under the Securities Act, covering the issuance of the Shares
issuable to the Holder upon exercise of the Warrant or the resale of the Shares
issuable upon exercise of the Warrant by the Holder.  The Company will use its
best efforts to have such registration statement declared effective as soon as
possible thereafter, and shall keep such registration statement current and
effective until such time as the Shares issuable upon exercise of the Warrant
may be sold by the Holder at any time without restriction or pursuant to the
provisions of Rule 144(k) of the Commission or until such earlier date as all of
the Purchased Shares registered pursuant to such registration statement shall
have been sold or otherwise transferred by the Holder to a third party.  The
Company shall also prepare and file with the Commission such amendments and
supplements to such registration statement (and the prospectus used in
connection therewith) as may be necessary to update and keep such registration
statement (and the prospectus used in connection therewith) current and
effective for such three-year period and to comply with the provisions of the
Securities Act with respect to the sale of all securities covered by such
registration statement.

              (b)  The Company shall not be required to effect a registration
pursuant to this Section 7.1: (i) after the Company has effected one (1)
registration pursuant to this Section 7.1, and such registration has either (A)
been declared or ordered effective or (B) the request for such registrations has
been subsequently withdrawn by the Holder (and such withdrawal is not based on
materially adverse information concerning the Company of which the Holder was
not

                                       5

<PAGE>

reasonably aware at the time of such request), in which case Company shall be 
required to effect a registration pursuant to this Section 7.1 upon a 
subsequent request of the Holder, but only at the Holder's expense; or (ii) 
if the Shares issuable upon exercise of the Warrant may be sold by the Holder 
at any time without restriction or pursuant to the provisions of Rule 144(k); 
or (iii) if Form S-3 (or a successor or similar form) is not available for 
such offering by the Holder; or (iv) if the Company shall furnish to the 
Holder following receipt of its written request for registration, a 
certificate signed on behalf of the Board of Directors by the Chairman of the 
Board stating that in the good faith judgment of the Board of Directors of 
the Company, it would be seriously detrimental to the Company and its 
shareholders for such registration statement to be filed and it is therefore 
essential to defer the filing of such registration statement, in which event 
the Company shall have the right to defer such filing for a period of not 
more than one hundred eighty (180) days after receipt of the Holder's request 
for registration.

    7.2  PIGGYBACK REGISTRATION.

         (a)  The Company shall notify the Holder in writing at least fifteen
(15) days prior to the filing of any registration statement under the Securities
Act for purposes of a public offering of securities of the Company (excluding
registration statements relating to employee benefit plans, business
acquisitions, and corporate reorganizations) and will afford the Holder an
opportunity to include in such registration statement all or part of the
Purchased Shares held by the Holder.  If the Holder desires to include in any
such registration statement all or any part of the Purchased Shares held by it,
it shall, within ten (10) days after the above-described notice from the
Company, so notify the Company in writing.  Such notice shall state the intended
method of disposition of the Purchased Shares by the Holder.  If the Holder
decides not to include all of its Purchased Shares in any registration statement
thereafter filed by the Company, the Holder shall nevertheless continue to have
the right to include any Purchased Shares in any subsequent registration
statement or registration statements as may be filed by the Company with respect
to offerings of its securities, all upon the terms and conditions set forth
herein.

         (b)  If the registration statement under which the Company gives 
notice under this Section 7.2 is for an underwritten offering, the Company 
shall so advise the Holder.  In such event, the right of the Holder to be 
included in a registration pursuant to this Section 7.2 shall be conditioned 
upon the Holder's participation in such underwriting and the inclusion of the 
Holder's Purchased Shares in the underwriting to the extent provided herein; 
and in such case, the Holder shall enter into an underwriting agreement in 
customary form with the underwriter or underwriters selected for such 
underwriting. Notwithstanding any other provision of the Agreement, if the 
underwriter determines in good faith that marketing factors make advisable a 
limitation of the number of shares to be underwritten, the number of shares 
that may be included in the underwriting shall be allocated, first, to the 
Company; second, to all holders (including Holder) entitled pursuant to 
written agreements with the Company to register their securities on a pro 
rata basis based on the total number of registrable shares of Common Stock 
held by all such holders;

                                       6

<PAGE>

and third, to any shareholder of the Company on a pro rata basis.  No such 
reduction shall reduce the securities being offered by the Company for its 
own account to be included in the registration.

         (c)  The Company shall have the right to terminate or withdraw any
registration initiated by it under this Section 7.2 prior to the effectiveness
of such registration whether or not the Holder has elected to include securities
in such registration.  The expenses of such withdrawn registration shall be
borne by the Company in accordance with Section 7.3 hereof.

         (d)  The Company shall not be required to effect a registration
pursuant to this Section 7.2 if the Shares issuable upon exercise of the Warrant
may be sold by the Holder at any time without restriction or pursuant to the
provisions of Rule 144(k).

    7.3  REGISTRATION PROCEDURES. The following provisions shall also be
applicable at the sole cost and expense of the Company:

         (a)  Following the effective date of a registration statement
registering the resale of Holder's Purchases Shares pursuant to Section 7.1 or
7.2 above, the Company shall, upon the request of the Holder, forthwith supply
such number of prospectuses meeting the requirements of the Securities Act as
shall be requested by the Holder to permit the Holder to make a public
distribution of all of its Purchased Shares, provided that the Holder shall from
time to time furnish the Company with such appropriate information (relating to
the intentions of the Holder) in connection therewith as the Company shall
request in writing.

         (b)  The Company shall use its best efforts to register or qualify the
Purchased Shares for sale in such states as the Holder reasonably requests.

         (c)  The Company shall bear the entire cost and expense of the
registration of securities provided for in this Section (but not the selling
expenses of the Holder).

         (d)  The Company shall indemnify and hold harmless the Holder from and
against any and all losses, claims, damages and liabilities (including
reasonable fees and expenses of counsel) arising out of or based upon any untrue
statement or alleged untrue statement of a material fact contained in any
registration statement or any prospectus included therein required to be filed
or furnished by reason of this Section 7 or otherwise or in any application or
other filing under, the Securities Act or any other applicable Federal or state
securities law, or arising out of or based upon any omission or alleged omission
to state therein a material fact required to be stated therein (i.e., in any
such registration statement, prospectus, application or other filing) or
necessary to make the statements therein not misleading, to which such person
may become subject, or any violation or alleged violation by the Company to
which such Person may become subject, under the Securities Act, the Securities
Exchange Act of 1934, as amended (the "Exchange Act"), or other Federal or state
laws or regulations, at common law or otherwise, except to the extent that as
such losses, claims, damages or liabilities are caused by any such

                                       7

<PAGE>

untrue statement or alleged untrue statement or omission or alleged omission 
based upon written information furnished to the Company by or on behalf of 
the Holder expressly for use therein; PROVIDED HOWEVER, that the Holder shall 
at the same time indemnify the Company, its directors, each officer signing 
the related registration statement, and each person, if any, who controls the 
Company within the meaning of the Securities Act, from and against any and 
all losses, claims, damages and liabilities (including reasonable fees and 
expenses of counsel) arising out of or based upon any untrue statement or 
alleged untrue statement of a material fact contained in any registration 
statement or any prospectus included therein required to be filed or 
furnished by reason of this Section, or otherwise or in any application or 
other filing under, the Securities Act or any other applicable Federal or 
state securities law, or arising out of or based upon any omission or alleged 
omission to state therein a material fact required to be stated therein 
(i.e., in any such registration statement, prospectus, application or other 
filing) or necessary to make the statements therein not misleading, to which 
such person may become subject, or any violation or alleged violation by the 
Holder to which the Company, its directors, each officer signing the related 
registration statement, and each person, if any, who controls the Company 
within the meaning of the Securities Act, may become subject, under the 
Securities Act, the Exchange Act, or other Federal or state laws or 
regulations, at common law or otherwise, to the extent that as such losses, 
claims, damages or liabilities are caused by any such untrue statement or 
alleged untrue statement or omission or alleged omission based upon written 
information furnished to the Company by or on behalf of the Holder expressly 
for use therein.

         (e)  In the event any person entitled to indemnification hereunder 
receives in writing a complaint, claim or other written notice of any loss, 
claim, damage, liability or action giving rise to a claim for indemnification 
under Section 7.3(d), the person claiming indemnification under Section 
7.3(d) shall promptly notify the person or persons against whom 
indemnification is sought (the "Indemnitor") of such complaint, notice, claim 
or action, and the Indemnitor shall have the right to investigate and defend 
any such loss, claim, damage, liability or action.  The person claiming 
indemnification shall have the right to employ separate counsel in any such 
action and to participate in the defense thereof but the fees and expenses of 
such counsel shall not be at the expense of the Indemnitor.  In no event 
shall the Indemnitor be obligated to indemnify any person for any settlement 
of any claim or action effected without the Indemnitor's consent, which 
consent shall not be unreasonably withheld.  

    8.   DISPUTES.

         8.1  ARBITRATION.

              (a)  Except as otherwise expressly provided for in Section 8.3
below, all disputes arising in connection with this Agreement shall be finally
settled by arbitration in Los Angeles County, California, in accordance with the
rules of the American Arbitration Association (the "Rules of Arbitration") and
judgment on the award rendered by the arbitration panel (the "Arbitration
Panel") may be entered in any court or tribunal of competent jurisdiction.

              (b)  Any party which desires to initiate arbitration proceedings
as provided in Section 8.1(a) above may do so by delivering written notice to
the other party (the "Arbitration Notice") specifying (A) the nature of the
dispute or controversy to be arbitrated, (B) the name and address of the

matters as may be required by the Rules of Arbitration.

              (c)  The party who receives an Arbitration Notice shall appoint
an arbitrator and notify the initiating party of such arbitrator's name and
address within 30 days after delivery of the Arbitration Notice; otherwise, a
second arbitrator shall be appointed at the request of the party who delivered
the Arbitration Notice as provided in the Rules of Arbitration.  The two
arbitrators so appointed shall appoint a third arbitrator who shall be the
chairman or the Arbitration Panel and who shall be of American nationality. 
Should the arbitrators appointed by the parties not agree upon the appointment
of the third arbitrator within 30 days of their appointment, the third shall be
appointed in accordance with the Rules of Arbitration.

              (d)  In any arbitration proceeding conducted pursuant to the
provisions of this Section 8, both parties shall have the right to discovery, to
call witnesses and to cross-examine the opposing party's witnesses, either
through legal counsel, expert witnesses or both, and such proceedings shall be
conducted in the English language.

         8.2  FINALITY OF DECISION.  All decisions of the Arbitration Panel
shall be final, conclusive and binding on all parties and shall not be subject
to judicial review.  The arbitrator shall divide all costs (other than fees of
counsel) incurred in conducting the arbitration proceeding and the final award
in accordance with what they deem just and equitable under the circumstances.

         8.3  LIMITATIONS.  Notwithstanding anything to the contrary contained
in Sections 8.1 and 8.2 above, any claim by either party for injunctive or other
equitable relief, including specific performance, may be brought in any court of
competent jurisdiction and any judgment, order or decree relating thereto shall
have precedence over any arbitral award or proceeding.

                              NON-COMPETITION AGREEMENT

    THIS NON-COMPETITION AGREEMENT (this "Agreement") is made as of the __th
day of September, 1996, by and among 3D SYSTEMS, INC., a California corporation
("3D") and Wayne O. Duescher ("Covenantor").

                                       RECITALS

    3D is purchasing from Keltool all of the assets (the "Assets") of Keltool,
together with the goodwill of Keltool (collectively, the "Business"), located
at 561 Shoreview Park Road, St. Paul, Minnesota  55126, pursuant to that certain
Asset Purchase Agreement dated August 30, 1996 (the "Purchase Agreement"). 
Covenantor has, in consideration of 3D entering into the Purchase Agreement,
which Purchase Agreement would not have been entered into by 3D if Covenantor
was unwilling to execute this Agreement, agreed to execute this Agreement and
perform his obligations hereunder.

                                      AGREEMENT

    NOW, THEREFORE, in reliance on the foregoing facts and in consideration of
the mutual covenants and agreements contained herein, the parties hereto agree
as follows:

    1.   NON-COMPETITION.  During the term hereof Covenantor agrees that, 
throughout the State of Minnesota, any other state or territory of the United 
States, or anywhere else in the World, he shall not, without the prior 
written consent of 3D (which consent may be withheld by 3D in the exercise of 
its sole and absolute discretion), directly or indirectly, own, manage, 
operate, join, control, finance or participate in the ownership, management, 
operation, control or financing of, or be connected as an officer, director, 
employee, principal, agent, representative, consultant, investor, owner, 
partner, stockholder (except as a holder of less than 2% of the issued and 
outstanding voting stock of a publicly held corporation), member, manager 
joint venturer or otherwise permit his name to be used by or in connection 
with, or lease, sell, or permit to use any real property or interest therein 
owned by him to, any business which is in any manner competitive with the 
Business, as conducted during the one year period prior to the date hereof; 
provided however, that Covenantor may continue to conduct the business of 
Keltech Engineering as currently conducted (the "Keltech Business").  It is 
agreed that the Keltech Business as currently conducted does not involve the 
manufacture of, sale of, or provision of services to enable or facilitate the 
manufacture or creation of, any hard tools or molds for hard tools.  In 
connection with and in addition to the foregoing, Covenantor agrees during 
the term hereof not to:  (i) hire or offer employment to any employee of 3D 
or any of its affiliates unless 3D first terminates the employment of such 
employee (except with respect to Matt Mullenburg, who Conventor may hire or 
offer employment to upon the earlier of (x) the relocation of the Assets

<PAGE>

and Business of Keltool to California, or (y) after six months after the 
Closing of the sale pursuant to the Purchase Agreement); or (ii) solicit, 
divert, or take away from 3D and its affiliates the business of any 
individual, corporation, trust, estate, partnership, joint venture, 
association, limited liability company, governmental bureau or other entity 
of whatsoever kind or nature ("Person") who or which at the time of the 
Closing or at any time within the three years prior to such time or at any 
time thereafter, was a customer of the Business.

    2.   CONFIDENTIAL INFORMATION.  Covenantor agrees that he will not, during
the term of this Agreement or at any time thereafter, use or disclose to any
Person other than 3D or its affiliates or their respective employees acting on
behalf of 3D or its affiliates, any customer list, potential customer list,
records, techniques, business secrets, trade secrets or any other information
with respect to the Business not available generally in the rapid prototype
tooling or moldmaking industries and not known to competitors of 3D or its
affiliates or other third parties unaffiliated with 3D or its affiliates
("Confidential Information") except as may be required by order of court or
other governmental agency, provided that Covenantor shall have first provided 
3D with notice of such order and an opportunity to object.

    3.   CONSIDERATION.  As consideration for the covenants and agreements of 
Covenantor contained herein, 3D has agreed to execute the Purchase Agreement 
and the exhibits thereto, and to perform its obligations thereunder.  The 
parties hereto agree that $250,000 of the Purchase Price (as that term is 
defined in the Purchase Agreement) has been allocated to the covenants and 
agreements of Covenantor contained herein.  Covenantor hereby acknowledges 
that 3D has been materially induced to enter into the Purchase Agreement and 
to make the payments provided for thereunder by and in reliance on 
Covenantor's execution of this Agreement, such execution of this Agreement 
being a condition precedent to 3D's obligation to consummate the Purchase 
Agreement, and agreement to comply with the covenants and agreements 
contained therein.

    4.   TERM AND TERMINATION.  The term of this Agreement shall commence on
the date hereof and shall terminate on that date which is five (5) years
following the date of this Agreement.

    5.   INJUNCTIVE RELIEF AND OTHER REMEDIES UPON BREACH BY COVENANTOR. 
Covenantor acknowledges and agrees that (i) the provisions of this Agreement 
are reasonable and necessary to protect the legitimate interests of 3D, and 
(ii) in the event of any breach by Covenantor of any of Covenantor's 
covenants and agreements contained herein, 3D would encounter extreme 
difficulty in attempting to prove the actual amount of damages suffered by it 
as a result of such breach, 3D would not have an adequate remedy at law in 
such event and, therefore, in addition to any other remedy it may have at law 
or in equity in the event of any such breach, 3D shall be entitled to seek 
and receive specific performance and temporary, preliminary and permanent 
injunctive relief from violation of any of the provisions of this Agreement 
from any court of competent jurisdiction without the necessity of proving the 
amount of any actual damages to it resulting from such breach.

    6.   MISCELLANEOUS.

         6.1  SUCCESSORS AND ASSIGNS.  This Agreement shall be binding upon 
and inure to the benefit of the parties hereto and their respective 
successors and assigns.  No party other than 3D may assign any of its rights, 
or delegate any of its duties or obligation, under this Agreement without the 
prior written consent of the other parties, and any such purported assignment 
or delegation shall be void AB INITIO.  Notwithstanding the foregoing, 3D, 
its affiliates, and its successors and assigns, may assign its rights and 
delegate its duties to any successor entity resulting from any liquidation, 
merger, consolidation, reorganization, or transfer of all or substantially 
all of the assets or stock of 3D or the Business of 3D.

         6.2  NOTICES.  All notices, demands and other communications
