EXHIBIT B


                 ORION, INC. CLASS B COMMON STOCK OPTION PLAN





    




                                  OPAL, INC.

                       CLASS B COMMON STOCK OPTION PLAN

     1. Purpose. The Opal, Inc. Class B Common Stock Option (the "Plan") is
intended (a) to provide a method whereby employees (including employees who
are officers and directors) of Opal, Inc. (the "Company") and its subsidiaries
who are making and are expected to continue making substantial contributions
to the successful management and growth of the Company and its subsidiaries
may be offered an opportunity to acquire shares of Class B Common Stock, par
value $.0001 per share, of the Company (the "Class B Common Stock"), in order
to acquire or increase their proprietary interests in the Company and their
incentive to remain, and to advance, in the employ of the Company and its
subsidiaries and (b) to attract and retain personnel of experience and ability
by granting such persons an opportunity to acquire a proprietary interest in
the Company. Accordingly, the Company may, from time to time, grant to such
employees as may be selected in the manner hereinafter provided, incentive
stock options ("Incentive Stock Options"), as defined in Section 422A of the
Internal Revenue Code of 1986, as amended (the "Code"), non-qualified stock
options ("Non-Qualified Stock Options") and restricted stock options
("Restricted Stock Options"), to purchase shares of Class B Common Stock of
the Company on the terms and conditions hereinafter established. The Incentive
Stock Options, Non-Qualified Stock Options and Restricted Stock Options are
sometimes referred to herein individually as an "Option" and collectively as
the "Options".

     2. Administration. The Plan shall be administered by a Stock Option
Committee (the "Committee") appointed by the Board of Directors of the
Company. The Committee shall consist of not fewer than three (3)
"disinterested persons," as that term is defined in subparagraph (d)(3) of
Rule 16b-3 ("Rule 16b-3"), as in effect from time to time under the Securities
Exchange Act of 1934, as amended (the "Exchange Act"). Subject to the terms
and conditions of the Plan, the Committee shall have full authority in its
discretion, from time to time, and at any time, to select the employees to
whom Options shall be granted, to determine the number of shares to be covered
by each Option, the time at which the Option shall be granted and the terms
and conditions of Option Agreements (as hereinafter defined), and, except as
hereinafter provided, the Option exercise price and the term during which the
Options may be exercised.

     The Board may at any time appoint or remove members of the Committee and
may fill vacancies, however caused, in the Committee. The Committee shall
select one of its members as its Chairman, and shall hold its meetings at such
times and places as it shall deem advisable. A majority of its members shall
constitute a quorum. All actions of the Committee shall be taken by a majority
of its members and can be taken by written consent in lieu of a meeting. The
Committee shall make such rules and regulations for the conduct of its
business as it shall deem advisable.

     3. Interpretation and Amendment. The interpretation, construction or
determination of any provision of the Plan by the Committee shall be final
conclusive. No

                                      1





    





member of the Board of Directors or the Committee shall be liable for an
action or determination made in good faith with respect to the Plan.

     The Board of Directors may, at any time, amend, alter, suspend or
terminate the Plan; provided, however, that any such action shall not impair
Options theretofore granted under the Plan, and provided further that without
the approval of the holders of at least the majority of the voting stock of
the Company voting at a duly held meeting: (a) the total number of shares of
Class B Common Stock in respect of which Options may be granted shall not be
increased (except as permitted by Paragraph 12); (b) the minimum option
exercise price shall not changed (except as permitted by Paragraph 12); and
(c) the option period during which outstanding Options granted under the Plan
may be exercised shall not be extended.

     4. Participants. Options may be granted under the Plan to key employees
of the Company and its subsidiaries (including employees who are also
directors or officers of the Company or its subsidiaries). Solely for the
purposes of granting Restricted Stock Options under the Plan, the term
"employees" shall also include consultants to the Company or any subsidiary.
The term "subsidiary" shall mean "subsidiary corporation" as defined in
Section 425 of the Code. Members of the Committee shall not be eligible to
participate in the Plan. No Incentive Stock Option shall be granted to an
employee who, at the time the Incentive Stock Option is granted, owns stock
possessing more than ten percent (10%) of the total combined voting power of
all classes of capital stock of the Company or any subsidiary of the Company;
provided, however, that an Incentive Stock Option may be granted to such an
employee if, at the time such Incentive Stock Option is granted, the option
exercise price is at least 110 percent (110%) of the fair market value of the
Class B Common Stock subject to the Incentive Stock Option, and such Incentive
Stock Option is by its terms not exercisable after the expiration of five (5)
years from the date such Incentive Stock Option is granted.

     Subject to the preceding paragraph, receipt of stock options under any
other stock option plan maintained by the Company or any subsidiary shall not,
for that reason, preclude an employee from receiving Options under the Plan.

     5. Amount of Shares of Class B Common Stock. The amount of shares of
Class B Common Stock which may be issued and sold pursuant to Options under
the Plan from time to time shall not exceed, in the aggregate 6,167,187 shares
of the Class B Common Stock of the Company, which shares of Class B Common
Stock may be issued and sold pursuant to Incentive Stock Options,
Non-Qualified Stock Options or Restricted Stock Options, as the Committee, in
its sole discretion, may determine. The number of shares of Class B Common
Stock issuable under the Plan may be increased to allow for the reissuance or
disposition of shares that have been issued upon the exercise of Options
granted under the Plan and reacquired by the Company in a manner not causing a
reduction in the capital of the Company. The shares of Class B Common Stock
reissued and sold under the Plan may be the Company's authorized but unissued
shares, or shares held in the Company's treasury.

                                      2





    





     Should any Option expire or terminate for any reason without having been
exercised in full, the unsold shares covered thereby shall be added to the
shares otherwise available for option hereunder.

     6. Terms and Conditions of Options. Option Agreements evidencing Options
granted pursuant to the Plan shall be in such form and on such terms as the
Committee shall, from time to time, approve, but subject, nevertheless, to the
following terms and conditions:

          (a)  The Option Agreement shall state the total number of shares of
               Class B Common Stock to which it relates and no fractional
               shares of Class B Common Stock shall be issued.

          (b)  The option exercise price per share of Class B Common Stock
               issuable upon the exercise of an Incentive Stock Option shall
               not be less than one hundred percent (100%) of the fair market
               value of the Class B Common Stock covered by such Option at the
               date such Option is granted.

          (c)  The option exercise price per share of Class B Common Stock
               issuable upon the exercise of a Non-Qualified Stock Option
               shall be determined by the Committee in its sole and absolute
               judgment.

          (d)  The option exercise price per share of Class B Common Stock
               issuable upon the exercise of a Restricted Stock Option shall
               be the par value thereof.

          (e)  Notwithstanding any provision of the Plan, the term of an
               Incentive Stock Option shall be for a period of not more than
               ten (10) years from the date such Incentive Stock Option is
               granted and the term of a Restricted Stock Option shall be for
               a period of not more than ten (10) years and one (1) day from
               the date such Restricted Stock Option is granted.

          (f)  An Option must be granted within ten (10) years of the earlier
               of the date the Plan is adopted or the date this Plan is
               approved by the Company's stockholders in accordance with
               Paragraph 22.

     7. Issuance of Shares in Trust; Vesting of Shares; Dividends and Voting
Rights.

          (a) Any other provision herein to the contrary notwithstanding, each
     share of Class B Common Stock with respect to which a Restricted Stock
     Option (or any part thereof) has been exercised by an employee who is a
     resident of Israel shall be issued by the Company to, and held in a trust
     (the "Trust") by, a trustee (the "Trustee") designated by the Board, for
     the benefit of such employee, until such time as such employee shall have

                                      3





    





instructed the Trustee, in writing, to release such share from the Trust;
provided, however, that such share shall be so released only upon the latter
of (a) two (2) years after the issuance thereof to the Trustee, or (b) the
time such share is vested (as provided in Section 7(b) below); provided
further that such share shall be released from the Trust only upon the full
payment of the option exercise price thereof, whether by discharge of the
"Note" (as hereinafter defined) or otherwise.

          (b)   (i) Unless otherwise provided by the Committee in any Option
                    Agreement, twenty five percent (25%) of the shares of
                    Class B Common Stock covered by an Option shall vest in
                    the employee on the first anniversary of the exercise date
                    of such Option, and 2.0833% of such shares shall vest in
                    such employee on the first day of each month following
                    such first anniversary. For purposes of this Section 7(b),
                    fractional shares shall be disregarded, and all remaining
                    unvested shares shall vest on the last such month.

               (ii) Any other provision herein to the contrary
                    notwithstanding, if any of the following occurs at any
                    time after the date hereof: (x) the liquidation of the
                    Company, (y) the sale or exchange of all or substantially
                    all of the assets of the Company, or (z) a merger or
                    consolidation of the Company with another corporation in
                    which the Company is not the surviving corporation or its
                    outstanding stock is converted into cash or securities of
                    a third party, then, in each such case, all the shares of
                    Class B Common Stock covered by Options shall vest in the
                    grantees thereof on the effective date of any such
                    transaction, or the record date on which shareholders of
                    the Company are entitled to participate in such
                    transaction shall be determined, whichever shall first
                    occur. Thereafter, all such shares of Class B Common Stock
                    shall be deemed "Free Shares" (as hereinafter defined),
                    and shall be free of any and all obligations of resale to
                    the Company.

          (c) Employee shall be deemed to have waived his rights with respect
     to any and all dividends and distributions payable on, or accrued with
     respect to, shares of Class B Common Stock which have not yet vested as
     of the date such dividend or distribution is declared or made. Subject to
     compliance with the applicable provisions of the Israel Currency Control
     Law - 1978 (the "Control Law"), all dividends (in cash or in kind)
     payable as shares of Class B Common Stock which vest on or before the
     date such dividend is declared (whether or not such shares were released
     from the trust) shall be remitted by the Company to the employee.

          (d) To the extent shares of Class B Common Stock are entitled to
     vote, the Trustee shall vote all such shares which are not yet vested
     pursuant to Section 7(b) hereof in

                                      4





    





such manner as may be directed by a person selected by the Committee. Each
Option Agreement shall include an irrevocable proxy by the employee who is a
party thereto in favor of such person covering all the shares subject to such
Option Agreement which are not yet vested pursuant to Section 7(b) hereof and
granting such person power to vote all such shares in his discretion.

     8. Restrictions on Disposition and Obligation of Resale.

          (a) Subject to the provisions of Section 7(b)(ii) hereof, shares of
     Class B Common Stock acquired by an employee pursuant to the exercise of
     a Restricted Stock Option under the Plan shall not be sold, transferred,
     or otherwise disposed of and shall not be pledged or otherwise
     hypothecated, except as provided in this Section 8 and Section 9 herein.
     (Any such sale, transfer or other disposition, or any pledge or other
     hypothecation shall hereinafter be referred to as a "disposition"). In
     the event of the termination of employment for any reason except
     retirement with the consent of the Company or death, such shares shall,
     except as provided below, and except with respect to shares fully vested
     pursuant to Section 7(b)(ii), be offered for resale to the Company at
     their original acquisition price. Shares as to which the vesting period
     referred to in Section 7(b) above, and the obligation of resale to the
     Company as provided in Section 8(b) herein, have lapsed in accordance
     with the provisions of the Plan and the applicable Option Agreement shall
     be referred to as "Free Shares." Shares as to which the vesting period
     referred to in Section 7(b) above, and obligation of resale to the
     Company as provided in Section 8(b) herein, did not lapse in accordance
     with the provisions of the Plan and the applicable Option Agreement shall
     be referred to as "Restricted Shares."

          (b) In the event of the termination of employment for any reason,
     shares of Class B Common Stock issued to the employee pursuant to the
     exercise of a Restated Stock Option under the Plan, which shares have not
     as of the date of termination of employment, become Free Shares pursuant
     to Section 7(b)(ii), or as otherwise defined in Section 8(a) above, shall
     become subject to an obligation of immediate resale to the Company within
     thirty (30) days following the termination of employment. Within sixty
     (60) days following a timely delivery of such shares, the Company will
     compensate the employee (at the original acquisition price) for such
     number of shares as the Company elects to purchase and will return to the
     employee any shares not so purchased. Restricted Shares that are not
     delivered to the Company within thirty (30) days following the
     termination of employment shall remain subject to the restrictions
     against disposition, and such restrictions shall not lapse as otherwise
     provided in this Section 8 and in the employee's Option Agreement.
     Nothing in this Section 8 shall require the Company to repurchase shares
     issued to employees under the Plan.

          (c) Notwithstanding any of the foregoing restrictions, any
     Restricted Shares acquired under the Plan may at any time be pledge or
     otherwise hypothecated to secure borrowing by the employee to obtain the
     acquisition price to be paid by the employee for such shares; provided,
     however, that the amount of such borrowing may not exceed the acquisition
     price of such shares.

                                      5





    





          (d) The provisions of this Paragraph 8 and the provisions of any
     Option Agreement between the Company and employee relating to the vesting
     period and the obligation of resale to the Company shall be applied
     according to their term or according to such other terms and conditions,
     or at such other times and dates, as the Board of Directors or the
     Committee may from time to time establish.

     9. Notice of Election under Section 83(b). With respect to the exercise
of Non- Qualified Stock Options or Restricted Stock Options, each employee
making an election under Section 83(b) of the Code and Regulations and Rulings
promulgated thereunder will provide a copy thereof to the Company within
thirty (30) days of the filing of such election with the Internal Revenue
Service.

     10. Termination of Employment. In the event that the holder of an Option
granted pursuant to the Plan shall cease to be employed by the Company or by
the subsidiaries of the Company for any reason other than disability (as
determined by the Committee in its sole discretion), retirement with the
consent of the Company, dismissal by the Company without cause, or death, any
Options granted to such holders pursuant to the Plan shall terminate
immediately; provided, that the Committee may in its sole discretion determine
that the holder of any Option may, if he ceases to be employed by the Company
or any subsidiary as a result of his dismissal for cause (as determined by the
Board of Directors in its sole discretion), exercise any Options that are
exercisable by him at the time he ceases to be employed by the Company or its
subsidiaries, and only to the extent such Options are exercisable as of such
time, within thirty (30) days after the date he ceases to be employed by the
Company or its subsidiaries. If the holder of an Option ceases to be employed
by the Company or any subsidiary as a result of his disability or his
retirement with the consent of the Company, then any Options that are
exercisable by him at the time he ceases to be employed by the Company or its
subsidiaries, and only to the extent such Options are exercisable as of such
time, may be exercised by him within two (2) years after the date of
disability or one (1) year after the date of retirement with the consent of
the Company (as determined by the Committee), respectively. If the holder of
an Option ceases to be employed by the Company or any subsidiary as result of
his dismissal without cause, then any Options that are exercisable by him at
the time he ceases to be employed by the Company or its subsidiaries, and only
to the extent such Options are exercisable as of such time, may be exercised
by him within sixty (60) days after the date he ceases to be employed by the
Company or its subsidiaries.

     Solely for purposes of the Plan, the transfer of an employee from the
employ of the Company to a subsidiary of the Company, or vice-versa, shall not
be deemed a termination of employment.

     11. Death. If a holder of an Option shall die while in the employ of the
Company or any subsidiary of the Company, his estate, personal representative
or beneficiary shall have the right to exercise any Options granted to the
optionholder pursuant to the Plan at any time within two (2) years from the
date of his death (or within such shorter period as may be

                                      6





    





specified in the Option Agreement), in respect of the total number of Shares
as to which he would have been entitled to exercise an Option at the time of
his death.

     12. Stock Splits, Mergers, etc. In case of any stock split, stock
dividend or similar transaction which increases or decreases the number of
outstanding shares of Class B Common Stock, appropriate adjustment shall be
made by the Board of Directors, whose determination shall be final, to the
number of shares of Class B Common Stock which may be purchased under the Plan
and the number and option exercise price per share of Class B Common Stock,
which may be purchased under any outstanding Options. Without derogating from
the provisions of Section 7(b)(ii), in the case of a merger, sale of assets or
similar transaction which results in a replacement of the Class B Common Stock
with stock of another corporation, the Company will make a reasonable effort,
but shall not required, to replace any outstanding Options granted under the
Plan with comparable options to purchase the stock of such other corporation,
or will provide for immediate maturity of all outstanding Options, with all
Options not being exercised within the time period specified by the Board of
Directors being terminated.

     13. Transferability. Options are not assignable or transferable except by
will or the laws of descent and distribution to the extent set forth in
paragraph 11 and during an optionholder's lifetime, may be exercised only by
him.

     14. Exercise of Options. An optionholder electing to exercise an Option
shall give written notice to the Company of such election and of the number of
shares of Class B Common Stock that he has elected to acquire. An optionholder
shall have no rights of a stockholder with respect to shares of Class B Common
Stock covered by his Option until after the date of issuance of a stock
certificate to him (or, on his behalf, to an "Authorized Dealer" (as
hereinafter defined) upon partial or complete exercise of his Option and the
payment of the exercise price thereof.

     15. Written Option Agreement. Agreements granting Options under the Plan
("Option Agreements") shall be in writing, duly executed and delivered by or
on behalf of the Company and the optionholder and shall contain such terms and
conditions as the Committee deems advisable. Unless otherwise specified in any
Option Agreement, if there is any conflict between the terms and conditions of
any Option Agreement and of the Plan, the terms and conditions of the Plan
shall control.

     16. Payment. The option exercise price shall be payable upon the exercise
of the Option in cash, by check or in shares of Class B Common Stock or, at
the discretion of the Board of Directors, by paying in cash, at the minimum,
the par value of the shares of Class B Common Stock being acquired and
executing a promissory note for the balance of the option exercise price (the
"Note"). If shares of Class B Common Stock are tendered as payment of the
option exercise price, the value of such shares shall be their fair market
value as of the date of exercise. If such tender would result in the issuance
of fractional shares of Class B

                                      7





    





Common Stock, the Company shall instead return the difference in cash or by
check to the employee.

     17. Term of Plan. The Plan shall terminate ten (10) years after the Plan
is adopted by the Board of Directors, and no Option shall be granted pursuant
to the Plan after their date.

     18. Application of Funds. The proceeds received by the Company from the
sale of shares of Class B Common Stock pursuant to the exercise of Options
granted under the Plan will be used for general corporate purposes.

     19. Obligation to Exercise Option. The granting of an Option shall impose
no obligation on the optionholder to exercise such option.

     20. Continuance of Employment. Neither the Plan nor any Option Agreement
shall impose any obligation on the Company or on any subsidiary of the Company
to continue the employment of any optionholder, any nothing in the Plan or in
any Option Agreement shall confer upon any optionholder any right to continue
in the employ of the Company or the subsidiary of the Company or conflict with
the right of either to terminate such employment at any time.

     21. Compliance with Securities Laws.

          (a) The Committee may, in its sole discretion, require that at the
     time an employee elects to exercise an Option, he shall furnish a written
     statement to the Company that he is acquiring the shares of Class B
     Common Stock for investment and without a view toward resale or other
     disposition of such shares.

          (b) The Committee may, in its sole discretion or acquired by law,
     require that an appropriate restrictive legend be placed upon each stock
     certificate representing shares of Class B Common Stock purchased by an
     employee pursuant to the Plan.

     22. Effectiveness of Plan. The Plan shall become effective on the date of
its adoption by the Board of Directors, but subject, nevertheless, to (a)
approval, within twelve (12) months thereof, by the shareholders representing
at least a majority of the voting stock of the Company or by such greater
percentage as may from to time be required under the laws of the State of
Delaware, and applicable rules or regulations under Rule 16b-3 and (a) such
approvals as may be required by any other public authorities.

     23. Tax Matters. All tax consequences under any applicable law which may
arise from the grant or exercise of an Option, from the payment for shares of
Class B Common Stock covered by an Option, from the resale of shares of Class
B Common Stock by an employee or from any other act of the employee in
connection therewith shall be borne solely by such employee, and such employee
shall indemnify the Company and each of its

                                      8





    




subsidiaries, and hold them harmless, against and from any liability for any
such tax or penalty thereon.

     24. Special Provisions Affecting Employees Resident in Israel. So long
as, and to the extent that, the Control Law shall so require, the following
provisions shall apply with respect to employees resident in Israel:

          (a) Delivery of certificates representing shares of Class B Common
     Stock shall be to a bank which is an authorized dealer (or its nominee
     company) in Israel ("Authorized Dealer") to hold for the benefit of the
     employee pursuant to the terms of the Plan and any applicable Option
     Agreement, and in conformity with the requirements of the Controller of
     Foreign Currency;

          (b) All payments of option exercise price by the employee, to the
     extent the same are made in currency other than New Israeli Shekels,
     shall be effected through an Authorized Dealer; and

          (c) The proceeds of any sale or transfer by an employee of shares of
     Class B Common Stock acquired by him pursuant to the exercise of an
     Option shall be remitted to Israel, and, to the extent the same were paid
     in currency other than New Israeli Shekels, shall be deposited with an
     Authorized Dealer immediately upon receipt thereof, and in all events not
     later than sixty (60) days after the date at which the certificate
     representing such shares was delivered to such employee for the resale
     thereof.


                                      9
