                        PROFESSIONAL SERVICES AGREEMENT

A.  PARTIES

    The four parties are Rose & Crangle, Ltd., a closely held Kansas 
corporation at 102 E. Lincoln Street in Lincoln, KS 67455-0285, and its 
predecessor (Rose & Crangle); Helisys, Inc., a publically listed Delaware 
corporation at 24015 Garnier Street in Torrance, CA 90505 and its predecessors 
(Helisys); Robert D. Crangle (Crangle); and Michael Feygin (Feygin).

B.  BACKGROUND

    Rose & Crangle began supplying consulting services to Helisys in 1985
and initially accepted stock in lieu of customary consulting fees; it is a
Helisys shareholder.  In March, 1996, Helisys completed its initial public stock
offering.

    Feygin invented the technology made and sold by Helisys.  He has been 
the president and major shareholder of Helisys since 1985, as well as on the 
Helisys board of directors (Board).

    Crangle, part owner and employee of Rose & Crangle, has been a 
management consultant since 1969 to, primarily, large corporations, institutions
and government agencies.  He is a degreed engineer, a former business school 
professor, an active Kansas lawyer, an experience board member, and a Board 
member since 1985.

C.  INTENT

    Each party wants (1) to have Feygin and Crangle on the Board, and (2) to
retain Crangle, through Rose & Crangle, as a consultant to Helisys.

D.  RESPONSIBILITIES OF THE PARTIES

1.  Feygin and Rose & Crangle agree to vote for Feygin and Crangle to be on the 
Board.

2.  Crangle agrees to be an employee of Rose & Crangle, and not of Helisys.

3.  Rose & Crangle agrees to make Crangle available to Helisys for forty-five to
fifty (45-50) days each year during the term of this agreement, targeted at 75%
or more in Torrance, for (i) consulting and (ii) Board membership, if elected.
Consulting includes senior management personal advice, counseling and guidance;
advice to increase the effectiveness and/or efficiency of existing Helisys
processes; management responsibilities; and responsibility for special projects
to alter existing Helisys operations or perform rate or one-time events. The
parties stipulate that Rose & Crangle has provided effective consulting services
to Helisys in all these areas since 1985, and that Crangle has been an effective
Board member since 1985. Crangle agrees to communicate regularly with Feygin on
Helisys matters; in general this means at least on a weekly basis when Crangle
is not in Torrance.

    The Rose & Crangle monthly fee during the Helisys fiscal year ending July

PROFESSIONAL SERVICES AGREEMENT - PAGE 3

     Should Helisys impose a general salary reduction on its then-employed 
workforce, including all its executives and managers, as a consequence of the 
general financial hardship of Helisys, the Rose & Crangle fees shall also then 
be reduced by the same proportion and for the same length of time.

signed by duly authorized representatives of the parties.  The fact that any 
party takes any action which is or seems to be inconsistent with this agreement 
but which has been or seems to have been accepted by any other party shall not 
act as or be interpreted as a constructive or actual change to this agreement 
absent a written, signed, dated amendment.

THIS AGREEMENT IS ACCEPTED BY THE PARTIES AS BINDING UPON THEMSELVES, THEIR 
HEIRS, SUCCESSORS AND ASSIGNS THIS 7th DAY OF MARCH, 1996, AND EACH PARTY HEREBY

Re:   Professional Services Contract

As stated in the Professional Services Agreement effective April 1, 1996 between
Rose & Crangle Ltd. and Helisys, Inc. a Delaware Corporation, an adjustment in 
the professional fees will be recalculated at the beginning of the new fiscal 
year. This fee change will be effective August 1, 1996.

Several calculations have been made based on the terms of the agreement. 
However, it has proven difficult to determine which employees and what salaries 
are to be considered as part of the salary pool. In an effort to resolve them, 
Helisys is offering to increase the monthly fee from $6,000 to $6,600 for fiscal
1997 (August 1, 1996 to July 31, 1997).

We would like you to officially accept the increase, if agreeable, in that it is
a change from the calculation process suggested in the Professional Services 
Agreement.

Sincerely,                                   Acceptance:
