RADIUS INC.

                        1994 DIRECTORS STOCK OPTION PLAN

            As Adopted by the Board of Directors on December 14, 1994

              As Approved by the Shareholders on February 15, 1995


     1.   PURPOSE.  This 1994 Directors Stock Option Plan (this "Plan") is
established to provide equity incentives for nonemployee members of the Board of
Directors of Radius Inc. (the "Company"), who are described in Section 6.1
below, by granting such persons options to purchase shares of stock of the
Company.

     2.   ADOPTION AND SHAREHOLDER APPROVAL.  This Plan shall become effective
on the date that it is adopted by the Board of Directors of the Company (the
"Effective Date").  This Plan shall be approved by the shareholders of the
Company, consistent with applicable laws, within twelve (12) months after the
Effective Date.  Options ("Options") may be granted under this Plan on or after
the Effective Date provided that, in the event that shareholder approval is not
obtained within the time period provided herein, this Plan, and all Options
granted hereunder, shall terminate.  No Option that is issued as a result of any
increase in the number of shares authorized to be issued under this Plan shall
be exercised prior to the time such increase has been approved by the
shareholders of the Company and all such Options granted pursuant to such
increase shall similarly terminate if such shareholder approval is not obtained.
So long as the Company is subject to Section 16(b) of the Securities Exchange
Act of 1934, as amended, (the "Exchange Act") the Company will comply with the
requirements of Rule 16b-3 with respect to shareholder approval.

     3.   TYPES OF OPTIONS AND SHARES.  Options granted under this Plan shall be
nonqualified stock options ("NQSOs").  The shares of stock that may be purchased
upon exercise of Options granted under this Plan (the "Shares") are shares of
the Common Stock of the Company, no par value.

     4.   NUMBER OF SHARES.  Subject to adjustment as provided in this Plan, the
total number of Shares reserved and available for grant and issuance pursuant to
the Plan shall be Shares consisting of 100,000 shares, plus the total number of
shares authorized for issuance, but not issued or subject to outstanding
options, under the Company's Directors' Stock Option Plan (the "Prior Plan") as
of the date of shareholder approval of this Plan.  Any shares issuable upon
exercise of options granted pursuant to the Prior Plan that expire or become
unexercisable for any reason after the date of shareholder approval of this Plan
without having been exercised in full, shall no longer be available for
distribution under the Prior Plan, but shall be available for distribution under
this Plan.  If any Option is terminated for any reason without being exercised
in whole or in part, the Shares thereby released from such Option shall be
available for purchase under other Options subsequently granted under this Plan.
At all times during the term of this Plan, the Company shall reserve and keep
available such number of Shares as shall be required to satisfy the requirements
of outstanding Options under this Plan.

     5.   ADMINISTRATION.  This Plan shall be administered by the Board of
Directors of the Company (the "Board").  The interpretation by the Board of any
of the provisions of this Plan or any Option granted under this Plan shall be
final and binding upon the Company and all persons having an interest in any
Option or any Shares purchased pursuant to an Option.

     6.   ELIGIBILITY AND AWARD FORMULA.

          6.1  ELIGIBILITY.  Options may be granted only to directors of the
Company who are not employees of the Company or any Parent, Subsidiary or
Affiliate of the Company, as those terms are defined in Section 17 below (each
an "Optionee").



          6.2  INITIAL GRANT.  Each Optionee who on or after the Effective Date
becomes a member of the Board will automatically be granted an Option for 10,000
Shares (the "Initial Grant").  Initial Grants shall be made on the later of the
Effective Date or the date such Optionee joins the Board.

          6.3  SUCCEEDING GRANTS.  Each year on the anniversary of the date of
the Optionee's Initial Grant hereunder or the anniversary of the date of
Optionee's initial grant under the Prior Plan, if the Optionee is still a member
of the Board, the Optionee will automatically be granted an Option for 2,500
Shares (the "Succeeding Grant").

          6.4     ADDITIONAL GRANT.  In addition, each director who received a
grant under the Prior Plan after August 30, 1994 and before the date of
shareholder approval of this Plan will receive a one time grant of an option to
purchase 1,250 shares of Common Stock upon shareholder approval of this Plan,
provided the director continues to serve on the Board at the time of such
approval.

     7.   TERMS AND CONDITIONS OF OPTIONS.  Subject to the following and to
Section 6 above:

          7.1  FORM OF OPTION GRANT.  Each Option granted under this Plan shall
be evidenced by a written Stock Option Grant ("Grant") in such form as the Board
shall from time to time approve, which Grant shall comply with and be subject to
the terms and conditions of this Plan.

          7.2  VESTING.  Options granted under this Plan shall be exercisable as
to 25% of the Shares on the first anniversary of the Grant Date for continuous
service as a director and as to an additional 25% of such Shares on each
subsequent anniversary of the Grant Date for continuous service as a director
thereafter.  Notwithstanding anything to the contrary, if an Optionee ceases to
serve as a member the Board, all Initial Grants and Succeeding Grants held by
such Optionee shall cease to vest.

          7.3  EXERCISE PRICE.  The exercise price of an Option shall be the
Fair Market Value (as defined in Section 17.4) of the Shares, at the time that
the Option is granted.

          7.4  TERMINATION OF OPTION.  Except as provided below in this Section,
each Option shall expire ten (10) years after the date of grant (the "Expiration
Date").  The date on which the Optionee ceases to be a member of the Board shall
be referred to as the "Termination Date".  An Option may be exercised after the
Termination Date only as set forth below:

               (a)  TERMINATION GENERALLY.  If the Optionee ceases to be a
member of the Board for any reason except death or disability, each Option, to
the extent (and only to the extent) that it would have been exercisable by the
Optionee on the Termination Date, may be exercised by the Optionee within three
(3) months after the Termination Date, but in no event later than the Expiration
Date.

               (b)  DEATH OR DISABILITY.  If the Optionee ceases to be a member
of the Board because of the death of the Optionee or the disability of the
Optionee within the meaning of Section 22(e)(3) of the Internal Revenue Code of
1986, as amended (the "Code"), each Option, to the extent (and only to the
extent) that it would have been exercisable by the Optionee on the Termination
Date, may be exercised by the Optionee (or the Optionee's legal representative)
within twelve (12) months after the Termination Date, but in no event later than
the Expiration Date.

     8.   EXERCISE OF OPTIONS.



          8.1  NOTICE.  Options may be exercised only by delivery to the Company
of an exercise agreement in a form approved by the Board stating the number of
Shares being purchased, the restrictions imposed on the Shares and such
representations and agreements regarding the Optionee's investment intent and
access to information as may be required by the Company to comply with
applicable securities laws, together with payment in full of the exercise price
for the number of Shares being purchased.

          8.2  PAYMENT.  Payment for the Shares may be made (a) in cash or by
check; (b) by surrender of shares of Common Stock of the Company that have been
owned by the Optionee for more than six (6) months (and which have been paid for
within the meaning of SEC Rule 144 and, if such shares were purchased from the
Company by use of a promissory note, such note has been fully paid with respect
to such shares) or were obtained by the Optionee in the open public market,
having a Fair Market Value equal to the exercise price of the Option; (c) by
waiver of compensation due or accrued to the Optionee for services rendered; (d)
provided that a public market for the Company's stock exists, through a "same
day sale" commitment from the Optionee and a broker-dealer that is a member of
the National Association of Securities Dealers (a "NASD Dealer") whereby the
Optionee irrevocably elects to exercise the Option and to sell a portion of the
Shares so purchased to pay for the exercise price and whereby the NASD Dealer
irrevocably commits upon receipt of such Shares to forward the exercise price
directly to the Company; (e) provided that a public market for the Company's
stock exists, through a "margin" commitment from the Optionee and a NASD Dealer
whereby the Optionee irrevocably elects to exercise the Option and to pledge the
Shares so purchased to the NASD Dealer in a margin account as security for a
loan from the NASD Dealer in the amount of the exercise price, and whereby the
NASD Dealer irrevocably commits upon receipt of such Shares to forward the
exercise price directly to the Company; or (f) by any combination of the
foregoing.

          8.3  WITHHOLDING TAXES.  Prior to issuance of the Shares upon exercise
of an Option, the Optionee shall pay or make adequate provision for any federal
or state withholding obligations of the Company, if applicable.

          8.4  LIMITATIONS ON EXERCISE.  Notwithstanding the exercise periods
set forth in the Grant, exercise of an Option shall always be subject to the
following limitations:

               (a)  An Option shall not be exercisable until such time as the
Plan or, in the case of Options granted pursuant to an amendment to the number
of shares that may be issued pursuant to the Plan, the amendment has been
approved by the shareholders of the Company in accordance with Section 15
hereof.

               (b)  An Option shall not be exercisable unless such exercise is
in compliance with the Securities Act of 1933, as amended (the "Securities
Act"), and all applicable state securities laws, as they are in effect on the
date of exercise.

               (c)  The Board may specify a reasonable minimum number of Shares
that may be purchased on any exercise of an Option, provided that such minimum
number will not prevent the Optionee from exercising the full number of Shares
as to which the Option is then exercisable.

     9.   NONTRANSFERABILITY OF OPTIONS.  During the lifetime of the Optionee,
an Option shall be exercisable only by the Optionee or by the Optionee's
guardian or legal representative, unless otherwise permitted by the Board.  No
Option may be sold, pledged, assigned, hypothecated, transferred or disposed of
in any manner other than by will or by the laws of descent and distribution.

     10.  PRIVILEGES OF STOCK OWNERSHIP.  No Optionee shall have any of the
rights of a shareholder with respect to any Shares subject to an Option until
the Option has been validly exercised.  No adjustment shall be made for
dividends or distributions or other rights for which


the record date is prior to the date of exercise, except as provided in this
Plan.  The Company shall provide to each Optionee a copy of the annual financial
statements of the Company, at such time after the close of each fiscal year of
the Company as they are released by the Company to its shareholders.

     11.  ADJUSTMENT OF OPTION SHARES.  In the event that the number of
outstanding shares of Common Stock of the Company is changed by a stock
dividend, stock split, reverse stock split, combination, reclassification or
similar change in the capital structure of the Company without consideration,
the number of Shares available under this Plan and the number of Shares subject
to outstanding Options and the exercise price per share of such Options shall be
proportionately adjusted, subject to any required action by the Board or
shareholders of the Company and compliance with applicable securities laws;
provided, however, that no certificate or scrip representing fractional shares
shall be issued upon exercise of any Option and any resulting fractions of a
Share shall be rounded up to the nearest Share; and provided, further, that the
exercise price of any Option may not be decreased to below the par value of the
Shares.

     12.  NO OBLIGATION TO CONTINUE AS DIRECTOR.  Nothing in this Plan or any
Option granted under this Plan shall confer on any Optionee any right to
continue as a director of the Company.

     13.  COMPLIANCE WITH LAWS.  The grant of Options and the issuance of Shares
upon exercise of any Options shall be subject to and conditioned upon compliance
with all applicable requirements of law, including without limitation compliance
with the Securities Act, compliance with all other applicable state securities
laws and compliance with the requirements of any stock exchange or national
market system on which the Shares may be listed.  The Company shall be under no
obligation to register the Shares with the SEC or to effect compliance with the
registration or qualification requirement of any state securities laws, stock
exchange or national market system.

     l4.  ACCELERATION OF OPTIONS.  In the event of a dissolution or liquidation
of the Company, a merger or consolidation in which the Company is not the
surviving corporation (other than a merger or consolidation with a wholly owned
subsidiary, a reincorporation of the Company in a different jurisdiction, or
other transaction in which there is no substantial change in the shareholders of
the Company), the sale of substantially all of the assets of the Company, or any
other transaction which qualifies as a "corporate transaction" under Section 424
of the Code wherein the shareholders of the Company give up all of their equity
interest in the Company and do not control the surviving entity, the vesting of
all options granted pursuant to the Plan will accelerate and the options will
become exercisable in full prior to the consummation of such event at such times
and on such conditions as the Board determines.

     15.  AMENDMENT OR TERMINATION OF PLAN.  The Board may at any time terminate
or amend this Plan but not the terms of any outstanding option; provided,
however, that the Board shall not, without the approval of the shareholders of
the Company, increase the total number of Shares available under this Plan
(except by operation of the provisions of Sections 4 and 11 above) or change the
class of persons eligible to receive Options.  Further, the provisions in
Sections 6 and 7 of this Plan shall not be amended more than once every six (6)
months, other than to comport with changes in the Code, the Employee Retirement
Income Security Act of 1974 or the rules thereunder.  In any case, no amendment
of this Plan may adversely affect any then outstanding Options or any
unexercised portions thereof without the written consent of the Optionee.

     16.  TERM OF PLAN.  Options may be granted pursuant to this Plan from time
to time within a period of ten (10) years from the Effective Date.

     17.  CERTAIN DEFINITIONS.  As used in this Plan, the following terms
shall have the following meanings:



        17.1  "PARENT" means any corporation (other than the Company) in an
unbroken chain of corporations ending with the Company if, at the time of the
granting of the Option, each of such corporations other than the Company owns
stock possessing 50% or more of the total combined voting power of all classes
of stock in one of the other corporations in such chain.

        17.2  "SUBSIDIARY" means any corporation (other than the Company) in an
unbroken chain of corporations beginning with the Company if, at the time of
granting of the Option, each of the corporations other than the last corporation
in the unbroken chain owns stock possessing fifty percent (50%) or more of the
total combined voting power of all classes of stock in one of the other
corporations in such chain.

        17.3  "AFFILIATE" means any corporation that directly, or indirectly
through one or more intermediaries, controls or is controlled by, or is under
common control with, another corporation, where "control" (including the terms
"controlled by" and "under common control with") means the possession, direct or
indirect, of the power to cause the direction of the management and policies of
the corporation, whether through the ownership of voting securities, by contract
or otherwise.

        17.4  "FAIR MARKET VALUE" shall mean, as of any date, the value of a
share of the Company's Common Stock determined as follows:

     (a)  if such Common Stock is then quoted on the Nasdaq National Market, its
          closing price on the Nasdaq National Market on the day of
          determination as reported in THE WALL STREET JOURNAL;

     (b)  if such Common Stock is publicly traded and is then listed on a
          national securities exchange, its closing price on the day of
          determination on the principal national securities exchange on which
          the Common Stock is listed or admitted to trading as reported in THE
          WALL STREET JOURNAL;

     (c)  if such Common Stock is publicly traded but is not quoted on the
          Nasdaq National Market nor listed or admitted to trading on a national
          securities exchange, the average of the closing bid and asked prices
          on the date of determination as reported in THE WALL STREET JOURNAL;
          or

     (d)  if none of the foregoing is applicable, by the Board in good faith.
