EMPLOYMENT AGREEMENT

AGREEMENT dated as of the 9th day of March, 2001, by and between Juno Online
Services, Inc., a Delaware corporation ("Company"), and Charles Ardai (the
"Employee").

      WHEREAS, the Company desires to continue to retain the Employee on the
terms and conditions hereinafter set forth, and the Employee is willing to
continue employment by the Company upon such terms and conditions;

      NOW, THEREFORE, in consideration of the foregoing and in consideration of
their mutual promises and agreements contained herein, the parties hereto agree
as follows:

      1. Employment

      Employment has commenced, and may be terminated by either party at any
time, for any reason, upon 30 days notice (the "Notice Period"), which notice
may be given either verbally or in writing. Notwithstanding the foregoing, the
Company may elect to terminate immediately upon notice, except that in this
event, the compensation and benefits set forth in Section 2 shall be continued
for the duration of the Notice Period. The Employee acknowledges and agrees that
he is an employee at will, and that just as the Employee is free to resign at
any time, the Company has the right to terminate the employment relationship at
any time for any lawful reason. The Employee acknowledges and agrees that no
representative of the Company may verbally change the at will employment
relationship between the Employee and the Company. References to time periods in
this Agreement shall not be construed or interpreted as promising or
guaranteeing employment for any specific duration or until any specific date.

      2. Compensation

      (a) BASE SALARY DURING THE COMPENSATION PERIOD. As compensation for the
Employee's services during the period beginning January 1, 2001 and ending on
December 31, 2001 (the "Compensation Period"), the Company shall pay the
Employee a base salary computed at an annual rate of $275,000 per year, prorated
to correspond to that portion of the Compensation Period during which the
Employee is actually employed with the Company, such base salary to be paid
semi-monthly.

      (b) BASE SALARY AFTER THE COMPENSATION PERIOD. As of the end of the
Compensation Period, the Employee's base salary may be increased or decreased,
or the manner in which the Employee is compensated may be changed, in the sole
discretion of the Company. Any such change in compensation shall be deemed to
modify only this Section 2 of this Agreement, and all other provisions of this
Agreement shall remain in effect following such change in compensation. In the
absence of any such change, the Employee's base salary shall remain the same as
it was during the Compensation Period.

      (c) YEAR-END BONUS DURING THE COMPENSATION PERIOD. The Company shall pay
the Employee a minimum guaranteed year-end bonus for the Compensation Period in
the amount of $200,000. Such bonus shall be paid to the Employee on a date to be
determined by the Company, which date shall ordinarily be no later than March
15th of the following calendar year, or as soon thereafter as is practicable. If
the Employee is involuntarily terminated (other than for cause) by the Company
during the Compensation Period, then any unpaid portion of the minimum
guaranteed bonus amount set forth in this Section 2(c) shall become payable
immediately upon such termination.

      (d) NON-REFUNDABLE ADVANCE AGAINST BONUS. In addition to the base salary
specified in Section 2(a) the Employee shall, during the Compensation Period,
receive non-refundable advances against the bonus specified in Section 2(c)
totaling $50,000, payable in two installments of $25,000 each on or about June
30, 2001 and on or about December 31, 2001. The Employee shall under no
circumstances be required to repay any correctly computed sum that has already
been paid to the Employee as a non-refundable advance against bonus pursuant to
the terms of this Section 2(d).

<PAGE>

      (e) YEAR-END BONUS AFTER THE COMPENSATION PERIOD. As of the end of the
Compensation Period, or as of the end of any subsequent calendar year, the
Employee's year-end bonus, if any, and/or the non refundable advance against
such year-end bonus, if any, may be increased, decreased, or eliminated, or the
manner in which the Employee is compensated may be changed, in the sole
discretion of the Company. Any such change in compensation shall be deemed to
modify only this Section 2 of this Agreement, and all other provisions of this
Agreement shall remain in effect following such change in compensation.
Subsequent to the Compensation Period, the Company shall not have any obligation
to continue to pay a year-end bonus to the Employee unless such an arrangement
is explicitly agreed to in writing by the Company.

      (f) DISCRETIONARY BONUS. In addition to the bonus payment set forth in
Section 2(c), the Company may (or may not) in its sole discretion pay the
Employee an additional discretionary bonus at any time. The award and amount of
any such bonus shall be determined by the Company in its sole discretion.

      (g) STANDARD COMPANY BENEFITS. In addition to the compensation outlined
elsewhere in this Section 2, the Company shall provide to the Employee all of
the benefits included in the Company's standard benefit package, which currently
include medical (hospitalization and major medical), dental, disability, life,
and accidental death and dismemberment insurance. Most of the cost of such
benefits shall be borne by the Company. However, in the case of coverage for the
Employee himself, the Employee contributes a nominal pre-tax amount to the cost
of the medical insurance; if the Employee wishes to obtain coverage for other
qualified family members, and arranges with the Company's insurance providers
(through the Company's Human Resources staff) to obtain such additional
coverage, the Employee will also be required to contribute part of the
incremental cost of such coverage. Individual and dependent medical insurance
contribution amounts are determined on a set scale, based on both the actual
cost of the insurance and on the Employee's base salary. The required
contribution will be borne by the Employee by means of a voluntary salary
reduction in the amount of the contribution implemented by the Company at the
request of the Employee.

      The standard benefit package also currently includes a flexible spending
account plan and a 401(k) retirement plan, available to all qualified full-time
employees after a certain period of employment with the Company. The 401(k)
retirement plan currently includes a matching program and a graded vesting
schedule; the Company does not contribute to the flexible spending account plan,
but the Employee may contribute pre-tax dollars. The Employee agrees that the
composition, providers, and all other aspects of the Company's standard benefit
package may be changed from time to time in the sole discretion of the
Management Company.

      (h) EXCLUSIVE COMPENSATION. The compensation and benefits described in
this Section 2 shall be the exclusive compensation due to the Employee from the
Company or any of its affiliates during or on account of the services of the
Employee. If directed by the Company, the Employee shall provide the services
described in this Agreement to one or more affiliates of the Company without
compensation other than as specified in this Section 2.

      3. Disclosure to the Company

      (a) DISCLOSURE OF INFORMATION TO THE COMPANY. The Employee shall promptly
disclose and deliver over to the Company, without additional compensation, to
the extent that such disclosure could reasonably be expected to be of interest
to the Company, in writing, or in such form and manner as the Company may
reasonably require:

            (i)   any and all algorithms, procedures, methods or techniques
directly related to electronic communication and/or electronic commerce or to
the Employee's work with the Company, and the essential ideas and principles
underlying such algorithms, procedures, methods or techniques, conceived,
originated, discovered, developed, evaluated, tested, or applied by the Employee
while employed by the Company, whether or not such algorithms, procedures,
methods or techniques are embodied in a computer program;

            (ii)  any and all programming, marketing, advertising, or financing
strategies, the essential ideas and principles on which such strategies are
based, and any information that might reasonably be expected to lead to the
development of such strategies, conceived, originated,

<PAGE>

discovered, developed, evaluated, tested, or employed by the Employee while
employed by the Company, whether or not such strategies are embodied in a
computer program;

            (iii) any and all Internet-related and other products and services,
and the essential ideas and principles underlying such products and services,
conceived, originated, adapted, developed, evaluated, tested, or applied by the
Employee while employed by the Company, whether or not such products or services
are embodied in a computer program, and whether or not marketed, sold, or
provided by the Company;

            (iv)  such information and data pertaining to the business,
operations, personnel, activities, financial status and affairs, current or
anticipated business or investment objectives or practices, current or
anticipated requirements for Internet-related or other products or services, and
other information relating to current or prospective investors, other current or
prospective funding sources, limited partners, shareholders, clients, customers,
accounts, joint venturers, or other business affiliates of the Company, and of
the officers, partners, principals, employees, and other persons affiliated with
such current or prospective investors, limited partners, shareholders, clients,
customers, accounts, joint venturers, or other business affiliates, as is known
to the Employee and as might reasonably be expected to be of value to the
Company in developing, maintaining, or expanding its current or prospective
business relationships with such current or prospective investors, limited
partners, shareholders, clients, customers, accounts, joint venturers, or other
business affiliates.

      (b) PERIOD COVERED; INFORMATION EXCLUDED. The provisions of this Section 3
shall apply to information acquired by the Employee at any time during his
employment with the Company, whether prior to or subsequent to the execution of
this Agreement.

      The Employee agrees not to disclose to the Company any confidential or
proprietary information belonging to any previous employer of the Employee that
is not affiliated with the Company, or belonging to any other party, without
first securing the written permission of such previous employer or other party.

      (c) DISCLOSURE UPON TERMINATION. Any information required to be disclosed
under this Section 3 that has not yet been disclosed by the Employee to the
Company at the time of the termination of the Employee's employment with the
Company, without regard to when or for what reason, if any, such employment
shall terminate, shall be disclosed to the Company in writing, or in such form
and manner as the Company may reasonably require, within 10 days of the
termination of the Employee's employment with the Company.

      4.  Confidential Information

      (a) DEFINITION. The parties acknowledge that, in order to permit the
Employee to successfully perform and/or continue to perform the duties
associated with his employment with the Company, it is necessary for the Company
to entrust the Employee with certain valuable proprietary information and
knowledge of certain modes of business operation ("Confidential Information")
which are essential to the profitable operation of the Company, and which give
the Company a competitive advantage over other firms pursuing related business
activities. In the context of this Agreement, the term "Confidential
Information" shall be deemed to include

            (i)   computer software or data of any sort developed (in the case
of software) or compiled (in the case of data) by the Company;

            (ii)  the fact that the Company uses, has used, or has evaluated for
potential use a particular computer program or system, if the disclosure of such
fact to a competitor of the Company might reasonably be expected to adversely
affect the competitive position of the Company relative to that of such a
competitor; provided, however, that information about the type of computers,
computer peripherals, operating systems, database systems, or other systems
software which the Company uses, has used, or has evaluated for potential use,
but which is not specific to any financial or Internet related application,
shall not by reason of this Section 4(a)(ii) be considered Confidential
Information;

            (iii) algorithms, procedures, methods, or techniques, or the
essential ideas and principles underlying such algorithms, procedures, methods,
or techniques, developed by the Company (but excluding any public domain
algorithm, procedure, or technique), whether or not such algorithms, procedures,
methods, or techniques are embodied in a computer program;

<PAGE>

            (iv)  the fact that the Company uses, has used, or has evaluated for
potential use any particular algorithm, procedure, or technique developed by
a party other than the Company, whether or not such algorithm, procedure, or
technique is embodied in a computer program, if the disclosure of such
information to a competitor of the Company might reasonably be expected to
adversely affect the competitive position of the Company relative to that of
such a competitor;

            (v)   the results of any programming, marketing, advertising,
financial, or other analysis conducted by the Company for its own internal use
(and not approved for dissemination to its customers, investors, consultants,
joint venturers, or other parties);

            (vi)  any information that would typically be included in the
Company's income statements, including, but not limited to the amount of the
Company's revenues, expenses, or net income;

            (vii) any plans for the business of the Company (whether or not such
plans have been reduced to writing); financial information concerning such plans
(including without limitation projected revenues, projected expenses, projected
net income and information concerning rates and costs of customer acquisition
and retention); descriptions of such business and technical aspects of or
relating to the operation of such business (including without limitation
algorithms, computer programs, processes or formulas that relate to computer and
network security, authentication, logging, accounting and distribution); and
products and services that the Company is considering offering to its
subscribers and/or to other persons;

            (viii) any other information gained in the course of the Employee's
employment with the Company that could reasonably be expected to prove
deleterious to the Company if disclosed to third parties, including without
limitation any information that could reasonably be expected to aid a competitor
of the Company in making inferences regarding the nature of the Company's
activities, where such inferences could reasonably be expected to adversely
affect the competitive position of the Company relative to that of such a
competitor;

            (ix)  any other information gained in the course of or incident to
the Employee's employment with the Company that the Company has received from a
third party and is required to hold confidential;

            (x)   any other information gained in the course of or incident to
the Employee's employment with the Company that the Company treats or designates
as Confidential Information and which is not publicly available.

      (b) USE AND DISCLOSURE.

            (i)   The Employee acknowledges that he has acquired and/or will
acquire Confidential Information in the course of or incident to his employment
with the Company. Accordingly, the Employee agrees that he shall not, directly
or indirectly, at any time, during the term of his employment with the Company
or at any time thereafter, and without regard to when or for what reason, if
any, such employment shall terminate, use or cause to be used any such
Confidential Information, whether acquired prior to or subsequent to the
execution of this Agreement, in connection with any activity or business except
the business of the Company, and shall not disclose such Confidential
Information to any individual, partnership, corporation, or other entity unless
such disclosure has been authorized in writing by the Company, or except as may
be required by any applicable law or by order of a court of competent
jurisdiction, a regulatory or self-regulatory body, or a governmental body.

            (ii)  The provisions of Section 4(b)(i) notwithstanding, the
Employee shall be free to disclose any information contained in any material
which the Company routinely makes available to the press and/or the general
public , and shall be free to disclose or use any information which is in or
which enters the public domain prior to the time of such disclosure or use
(except where such information enters the public domain as a result of
unauthorized actions of the Employee). The Employee acknowledges, however,
that (A) a large number of programming techniques and programming strategies,
and a large number of analyses, observations and findings from which such
computer programming techniques and strategies might be derived, have been or
may be reported in the open literature, or may otherwise have entered or may
enter the public domain, and that one of the Company's most valuable forms of
Confidential Information is its accumulated knowledge, based on research,

<PAGE>

analysis, and experimentation not reported in the open literature or otherwise
falling within the public domain, of which of these programming techniques, and
programming strategies, and which of these analyses, observations, and findings,
are likely to form the basis for practical, profitable business applications for
the Company ("Confidential Applicability Information"). The Employee thus agrees
that he shall not, directly or indirectly, at any time, during the term of his
employment with the Company, or at any time thereafter, and without regard to
when or for what reason, if any, such employment shall terminate, use or cause
to be used any Confidential Applicability Information in connection with any
activity or business except the business of the Company, and shall not disclose
such Confidential Applicability Information to any individual, partnership,
corporation, or other entity, unless what would otherwise be deemed to
constitute Confidential Applicability Information is itself in or itself enters
the public domain by some means other than as a result of unauthorized actions
of the Employee, or unless such disclosure has been authorized in writing by the
Company, or except as may be required by any applicable law or by order of a
court of competent jurisdiction, a regulatory or self-regulatory body, or a
governmental body.

            (iii) In the event that the Employee is required to disclose
Confidential Information or Confidential Applicability Information pursuant to
judicial or administrative process or other requirements of law, the Employee
will (A) notify the Company of his receipt of such process within 24 hours of
such receipt, and prior to any disclosure being made, (B) to the extent
reasonably practicable, consult with the Company on the advisability of taking
steps to resist or narrow such request provided that the ultimate decision shall
be that of the Employee, and (C) if disclosure is required or deemed advisable,
cooperate with the Company in any attempt that it may make in order to obtain an
order or other reliable assurance that confidential treatment will be accorded
to designated portions of such information. If no such order is obtained by the
Company, disclosure of such information by the Employee shall not be deemed a
violation of this Agreement. If such an order is obtained, then disclosure of
the information covered by such order in the manner described in the order shall
not be deemed a violation of this Agreement. The Employee shall be entitled to
reimbursement for his reasonable expenses, including the fees and expenses of
his counsel, in connection with action taken pursuant to this paragraph.

            (iv) The provisions of Sections 4(b)(i), 4(b)(ii), and 4(b)(iii)
notwithstanding, the Employee shall be free to disclose or use any
information which was obtained by the Employee prior to his employment with
the Company (subject to any obligations owed by the Employee to such previous
employers with respect to such information), or which is obtained by the
Employee subsequent to and independent of his relationship with the Company.

            (v) The provisions of Section 4(b)(i), 4(b)(ii), and 4(b)(iii)
notwithstanding, the Employee shall, with the prior written permission of the
Company, be free to disclose selected Confidential Information and/or
Confidential Applicability Information to a limited number of parties for the
purpose of securing employment subsequent to the Employee's employment with the
Company or progressing professionally, provided further that where such
disclosure would not be harmful to the Company, such permission shall not be
unreasonably withheld. For purposes of this Section 4(b)(v), the termination of
the Employee's employment with the Company shall not in itself be deemed harmful
to the Company, even if such termination is voluntary.

      (c) RETURN AND OWNERSHIP OF DOCUMENTS AND WORK PRODUCT. Upon the
termination of the Employee's employment with the Company for any reason, the
Employee promises and agrees to return immediately to the Company any and all
Confidential Information and all other materials or documents, including without
limitation mailing lists, rolodexes, computer print-outs, and computer disks and
tapes, belonging to the Company which contain information pertaining to the
Company's business, methods, clients, potential clients, customers, potential
customers, investors, potential investors, funding providers, potential funding
providers, or employees, unless the Company consents in writing to the
Employee's retention thereof.

      (d) OWNERSHIP OF INTELLECTUAL PROPERTY. All right, title, and interest of
every kind and nature whatsoever, whether now known or unknown, in and to any
intellectual property

<PAGE>

("Intellectual Property"), including without limitation any ideas, inventions
(whether or not patentable), designs, improvements, discoveries, innovations,
patents, trademarks, service marks, trade dress, trade names, trade secrets,
works of authorship, copyrights, films, audio and video tapes, other audio and
visual works of any kind, scripts, sketches, models, formulas, tests, analyses,
software, firmware, computer processes, computer and other applications,
creations, properties, and any documentation or other memorialization containing
or relating to the foregoing, in each case discovered, invented, created,
written, developed, taped, filmed, furnished, produced, or disclosed by or to
the Employee in the course of rendering services to the Company shall, as
between the parties hereto, be and remain the sole and exclusive property of the
Company for any and all purposes and uses whatsoever, and the Employee and his
successors and assigns shall have no right, title, or interest of any kind or
nature therein or thereto, or in or to any results and proceeds therefrom. The
Company shall have all right, title, and interest in such Intellectual Property,
whether such Intellectual Property is conceived by the Employee alone or with
others and whether conceived during regular working hours or other hours.

      The Employee makes, and agrees to make and execute, any assignment
necessary to perfect the Company's right, title, and interest in Intellectual
Property, and agrees to perform any act reasonably requested by the Company in
furtherance of any such assignment, and/or of perfecting the Company's rights in
Intellectual Property.

      (e) NO WAIVER OF TRADE SECRET PROTECTION. Nothing contained in this
Agreement shall be deemed to weaken or waive any rights related to the
protection of trade secrets or confidential business information that the
Company may have under common law or any applicable statutes or rules.

      5. Competition While Employed

      During the period of his employment with the Company, the Employee will
not, directly or indirectly, without the written consent of the Company, and
whether or not for compensation, either for his own account or as an
employee, officer, agent, consultant, director, owner, partner, joint
venturer, shareholder, investor, or in any other capacity:

      (a) perform a function which is of the same nature as, or substantively
similar to, a function that the employee performs for the Company; or

      (b) engage in any activity or business which is the same nature as, or
substantively similar to, an activity or business of the Company or an activity
or business which the Company is developing and of which the Employee has
knowledge.

      6.  Interference with Relationships

      (a) RESTRICTIONS ON INTERFERENCE. While employed by the Company, and for a
period of 18 months after the date the Employee ceases to be employed by the
Company, without regard to when or for what reason, if any, such employment
shall terminate (the "Termination Date"), the Employee shall not, directly or
indirectly, without the written consent of the Company, and whether or not for
compensation, either on his own behalf or as an employee, officer, agent,
consultant, director, owner, partner, joint venturer, shareholder, investor, or
in any other capacity (except in the capacity of an employee or officer of the
Company acting for the benefit of the Company), knowingly:

            (i)   interfere with an ongoing (as of the Termination Date)
relationship between the Company and one of its customers (except as permitted
under the provisions of Sections 6(b) and 6(c) below) by providing or offering
to provide a product or service to that customer which, as of the Termination
Date, was provided to that customer by a business unit of the Company in which
the Employee worked during his employment with the Company, if by so doing, the
Employee might reasonably be expected to cause the Company to suffer a loss of
profits from or other damage to its business relationship with that customer;

            (ii) interfere with an ongoing (as of the Termination Date) joint
venture, strategic alliance, licensing agreement, distribution relationship,
advertising relationship, or similar agreement or relationship between the
Company and another business entity (the "Joint Venture Relationship") by
entering into or proposing to enter into a substantially similar business
relationship with that entity, if the Employee was

<PAGE>

directly involved in that Joint Venture Relationship during his employment with
the Company, and if by so doing, the Employee might reasonably be expected to
cause the Company to suffer a loss of profits that would otherwise accrue to the
Company in connection with that Joint Venture Relationship, or to suffer other
damage to that Joint Venture Relationship;

            (iii) employ, or retain as a consultant or contractor, or cause
to be so employed or retained, or enter into a partnership or business
venture with, any person (a "Related Person") who at the time of such action
(A) is an employee of the Company or the D. E. Shaw Group; (B) has been
employed by the Company or the D. E. Shaw Group at any time within the
previous 18 months; (C) is a consultant, sales agent, contract programmer, or
other independent agent who is retained on a full-time or substantially
full-time basis by the Company or the D. E. Shaw Group; or (D) has been
retained on a full-time or substantially full-time basis by the Company or
the D. E. Shaw Group as a consultant, sales agent, contract programmer, or
other independent agent at any time within the previous 18 months; or

            (iv) solicit, persuade, encourage, or induce any employee of the
Company or the D. E. Shaw Group (or any consultant, sales agent, contract
programmer, or other independent agent who is retained on a full-time or
substantially full-time basis by the Company or the D. E. Shaw Group) to
cease his employment with or retention by the Company or the D. E. Shaw
Group.;

            (v) accept or solicit investment capital or debt financing
(directly or indirectly) from, or accept or solicit employment with, or
accept or solicit a consulting assignment with, any individual or entity, or
an officer, partner, principal, or affiliate of any entity, or another entity
managed by or otherwise affiliated with an officer, partner, principal, or
affiliate of any entity, that, as of the Termination Date or at any time
within the 18 months immediately preceding the Termination Date, provided or
arranged for the provision of more than 20 percent of the capital of the
Company.

      (b) EXCEPTIONS TO PREVENT UNDUE HARDSHIP. In the event that the
application of Section 6(a)(i) and/or Section 6(a)(ii) would, in the Company's
judgment, cause undue hardship to the Employee, the Company, upon written
request by the Employee, provide to the Employee a written instrument
authorizing such specific exceptions to the provisions of Section 6(a)(i) and/or
Section 6(a)(ii) as the Company shall determine are reasonably necessary to
prevent such undue hardship, the provisions of which instrument shall thereafter
be deemed to supersede the corresponding provisions of Section 6(a)(i) and/or
Section 6(a)(ii).

      (c) PRIOR RELATIONSHIPS. The provisions of Section 6(a) notwithstanding,
the Employee shall not by reason of Section 6(a) be restricted from resuming,
after the termination of his employment with the Company, any employment or
business relationship that preceded his employment with the Company, or from
providing or offering to provide any product or service to a customer which the
Employee provided to that customer at any time prior to his employment by the
Company; provided, however, that Section 4 and the other provisions of this
Section 6 shall continue to apply.

      (d) EXCEPTION FOR UNRELATED ACTIVITIES. The provisions of Section 6(a)
notwithstanding, the Employee shall become free nine months after the
Termination Date to employ, retain, cause to be employed or retained, or enter
into a business relationship with any Related Person provided that neither the
Employee nor any Related Person directly or indirectly engages in business
activities competitive with the business activities of the Company in the course
of such employment, retention, or business relationship.

      (e) NO WAIVER OF COMMON LAW OR STATUTORY PROTECTION. Nothing contained in
this Agreement shall be deemed to weaken or waive any of the Company's rights or
protections that may be accorded by statute or common law as regards the conduct
of the Employee with respect to the Company's business, investors, customers,
clients, joint venture partners, employees, consultants, or contractors. The
Employee authorizes the Company to disclose this Agreement to any person at any
time, including without limitation any employer or prospective employer of the
Employee.

<PAGE>

      7. Reasonableness of Covenants

      (a) CERTAIN RECOGNITIONS. The Employee acknowledges that the restrictions
specified in Sections 4, 5, and 6 of this Agreement are reasonable in view of
the nature of the business in which the Company is engaged, the Employee's
position with the Company, the previous relationship between the Company and the
D. E. Shaw Group and the Employee's knowledge of the Company's business.

      The Employee recognizes that the amount of his compensation reflects his
Agreement in Sections 4, 5, and 6, and acknowledges that he will not be subject
to undue hardship by reason of his agreements set forth in Sections 4, 5, and 6.

      (b) MODIFICATION OF RESTRICTION. Notwithstanding anything contained in
Sections 4, 5, or 6 of this Agreement to the contrary, if a court of competent
jurisdiction should hold any restriction specified in Sections 4, 5, or 6 to be
unreasonable, unenforceable, illegal or invalid, then that restriction shall be
limited to the extent necessary to be enforceable, and only to that extent. In
particular, and without limitation on the foregoing, if any provision of
Sections 4, 5, or 6 should be held to be unenforceable as to scope or length of
time or geographical area involved, such provision shall be deemed to be
enforceable as to, and shall be deemed to be amended to cover, the maximum
scope, maximum length of time, or broadest area, as the case may be, which is
then lawful.

      (c) SURVIVAL OF COVENANTS. The obligations of the Employee under Sections
4 and 6 of this Agreement shall survive the termination of this Agreement and of
his employment with the Company.

      8. Regulatory Compliance

      The Employee agrees to abide by all applicable securities laws and all
applicable rules and regulations of the Securities Exchange Commission, the
National Association of Securities Dealers, the Nasdaq National Market, and all
other applicable self-regulatory organizations.

      9.  Remedies/Arbitration

      (a) INJUNCTIONS, RESTRAINING ORDERS, AND OTHER EQUITABLE RELIEF. The
Employee acknowledges that breach or threatened breach of Sections 4, 5, or 6 of
this Agreement will cause the Company or, as the case may be, the D. E. Shaw
Group irreparable harm for which there is no adequate remedy at law, and as a
result of this, the Company or, as the case may be, the D. E. Shaw Group shall
be entitled to the issuance by a court of competent jurisdiction of an
injunction, restraining order, or other equitable relief in favor of itself,
without the necessity of posting a bond, restraining the Employee from
committing or continuing to commit any such violation. Any right to obtain an
injunction, restraining order, or other equitable relief hereunder shall not be
deemed a waiver of any right to assert any other remedy the Company or, as the
case may be, the D. E. Shaw Group may have at law or in equity. The right of the
Company or, as the case may be, the D. E. Shaw Group to seek equitable relief
under this Agreement shall be in addition to (and not in derogation of) the
requirement imposed on each party hereto to arbitrate disputes as provided in
Section 9(b) below.

      (b) MANDATORY ARBITRATION. The Employee and the Company agree that any
claim, controversy or dispute between the Employee and the Company (including
without limitation its affiliates, officers, employees, representatives, or
agents) arising out of or relating to this Agreement, the employment of the
Employee, the cessation of employment of the Employee, or any matter relating to
the foregoing shall be submitted to and settled by arbitration in a forum of the
American Arbitration Association ("AAA") located in New York County in the State
of New York and conducted in accordance with the National Rules for the
Resolution of Employment Disputes. In such arbitration: (i) each arbitrator
shall agree to treat as confidential evidence and other information presented by
the parties to the same extent as Confidential Information under this Agreement
must be held confidential by the Employee, (ii) the arbitrators shall have no
authority to amend or modify any of the terms of this Agreement, and (iii) the
arbitrators shall have ten business days from the closing statements or
submission of post-hearing briefs by the parties to render their decision. Any
arbitration award shall be final and binding upon the parties, and any court,
state or federal, having jurisdiction may enter a judgment on the award. The
foregoing requirement to arbitrate claims, controversies, and disputes applies
to all claims or

<PAGE>

demands by the Employee, including without limitation any rights or claims the
Employee may have under the Age Discrimination in Employment Act of 1967 (which
prohibits age discrimination in employment), Title VII of the Civil Rights Act
of 1964 (which prohibits discrimination in employment based on race, color,
national origin, religion, sex, or pregnancy), the Americans with Disabilities
Act of 1991 (which prohibits discrimination in employment against qualified
persons with a disability), the Equal Pay Act (which prohibits paying men and
women unequal pay for equal work) or any other federal, state, or local laws or
regulations pertaining to the Employee's employment or the termination of the
Employee's employment.

      (c) RECOVERY OF LEGAL FEES.  If one of the parties to this Agreement (the
"Plaintiff") should bring a proceeding against the other party (the "Defendant")
in connection with an alleged breach or threatened breach of this Agreement,
and if such proceeding is ultimately resolved by an order or a judgment in
favor of the Defendant, by a voluntary discontinuance with prejudice by the
Plaintiff, or by an arbitration decision wholly in favor of the Defendant,
the Plaintiff will, upon presentation by the Defendant of appropriate
evidence of the amount and nature of the expense incurred, reimburse the
Defendant in an amount equal to the lesser of:

            (i) the cost of all reasonable legal fees actually incurred by the
Defendant in connection with such litigation or arbitration; or

            (ii) $100,000.

      (d) FORUM. Each party submits to the jurisdiction of the courts, state and
federal, and arbitration forums (set forth in Section 9(b)) located in the State
of New York.

      10. Relationship of the Parties

      The relationship between the Company and the Employee hereunder is agreed
to be solely that of employee and employer. Nothing contained herein and no
modification of responsibility or compensation made hereafter shall be construed
so as to constitute the parties as partners or joint venturers.

unenforceable by a court of competent jurisdiction shall not affect any other
provision of this Agreement, which shall remain in full force and effect.

      14. Waiver

      The failure of a party to insist upon strict adherence to any term of this
Agreement on any occasion or occasions shall not be considered a waiver thereof
or deprive that party of the right thereafter to insist upon strict adherence to
that term or any other term of this Agreement.

beneficiaries, or legal representatives without the Company's prior written
consent; provided, however, that nothing in this Section 16 shall preclude the
Employee from designating a beneficiary to receive any benefit payable hereunder
upon his death, or the executors, administrators, or other legal representatives
of the Employee or his estate from assigning any

EXHIBIT 4.6    
  

 
 

Form of Incentive Stock Option Contract for Executives pursuant to the 1996 Stock Incentive Plan    
  

 
 

OPTION CERTIFICATE
  (Incentive Stock Option for Executives)    
  

    THIS IS TO CERTIFY that 3D Systems Corporation, a Delaware corporation (the "Company"), has granted to the
employee named below an incentive stock option (the "Option") to purchase shares of the Company's Common Stock (the
"Shares"), under its 1996 Stock Incentive Plan (the "Plan"), and upon the terms and conditions
determined by the Compensation Committee (the "Committee") of the Board of Directors of the Company (the "Board"), as follows: 

    Name
of Employee: 

    Address
of Employee: 

    Number
of Shares: 

    Option
Exercise Price: 

    Date
of Grant: 

    Option
Expiration Date: 

    Exercise Schedule:  The Option shall become exercisable with respect to 25% of the number of shares subject to this
Option (rounded up or down to the nearest whole number) on each of the first four anniversaries of the Date of Grant, provided however that, in the event of an acquisition by any individual, entity or
group (within the meaning of Section 13(d)(3) or 14(d)(2) of the Securities Exchange Act of 1934, as amended (the "Exchange Act") of beneficial ownership (within the meaning of
Rule 13d-3 of the Rules and Regulations of the Securities and Exchange Commission under the Exchange Act) of at least 51% or more of the combined voting power of the then
outstanding voting securities of the Company entitled to vote generally in the election of directors, the Option shall become fully vested and immediately exercisable. Installments shall be
cumulative, and the Option may be exercised as to any and all shares of Common Stock covered by an installment at any time after the installment becomes exercisable and prior to the expiration of
termination of the Option. 

    Summary of Other Terms:  This Option is defined in the Stock Option Agreement (Incentive Stock Option) (the
"Option Agreement") which is attached to this Option Certificate (the "Certificate") as Annex I. This
Certificate summarizes certain of the provisions of the Option Agreement for your information, but is not complete. Your rights are governed by the Option Agreement,  not by this summary. The Company
strongly suggests that you carefully review the full Option Agreement prior to signing this Certificate or exercising
the Option. 

    Among
the terms of the Option Agreement are the following: 

    Termination of Employment:  While the Option terminates on the Option Expiration Date, it will terminate earlier if you
cease to be employed by the Company or the direct or indirect subsidiary of the Company with whom you are employed (transfer of employment from one subsidiary to another will not constitute
termination of employment). If your employment ends due to death, the Option terminates eighteen months after the date of death, and is exercisable during such eighteen-month period as to the portion
of the Option which had vested prior to the date of death. If your employment ends due to disability, the Option terminates twelve months after the date of disability, and is exercisable during such
twelve-month period as to the portion of the Option which had vested prior to the date of disability. If your employment ends primarily as a result of an act of misconduct described in
Section 4(g) of the Plan, or during the period when your rights under the Option have been suspended by the Company pursuant to that Section, the Option will terminate immediately. In all other
cases, including retirement, the Option terminates ninety days after the date of termination of 

 

employment, and is exercisable during such time period as to the portion of the Option which had vested prior to the date of termination of employment. See Section 5 of the attached Option
Agreement. 

    Transfer:  The Option is personal to you, and cannot be sold, transferred, assigned or otherwise disposed of to any
other person, except upon your death. See Section 13(d) of the attached Option Agreement. 

    Exercise:  You can exercise the Option (while it is exercisable), in whole or in part, by delivering to the Company a
Notice of Exercise identical to Exhibit "A" attached to the Option Agreement, accompanied by payment of, or provision pursuant to the Option Agreement for the payment of, the Exercise Price for the
Shares to be purchased. The Company may require you to submit certain written reassurances to the Company with respect to your status as a shareholder. The Company will then issue a certificate to you
for the Shares you have purchased. You are under no obligation to exercise the Option. See Section 4 of the attached Option Agreement. 

    Reload Option:  If and to the extent that the Exercise Price is paid by delivery of shares of the Company's Common Stock
(see Section 4(b) of the attached Option Agreement), you will automatically be granted a new option (a "Reload Option") for a like number of shares, with an exercise price equal to the market
value of a share of Common Stock on the date of exercise, and a term equal to the term of the Option. See Section 4(d) of the attached Option Agreement. 

    Adjustments upon Recapitalization:  The Option contains provisions which affect your rights in the event of stock
splits, stock dividends, mergers and other major corporate reorganizations. See Section 6 of the attached Option Agreement. 

    Waiver:  By signing this Certificate, you will be agreeing to all of the terms of the Option Agreement, including those
not summarized in this Certificate. You will waive your rights to options or stock which may otherwise have been promised to you. See Section 7 of the attached Option Agreement. 

    Withholding:  The Company may require you to make any arrangements necessary to insure the proper withholding of any
amount of tax, if any, required to be withheld by the Company as a result of the exercise of the Option. See Section 10 of the attached Option Agreement. 

    Value of Shares:  If you are granted an Option first exercisable in any one calendar year to purchase Shares valued in
excess of $100,000 on the grant date, then for tax purposes the incremental portion of
such Shares with an aggregate fair market value in excess of $100,000 shall be treated as non-statutory stock options, rather than as incentive stock options (as that term is defined in
Section 422 of the Internal Revenue Code of 1986, as amended).
