                                 TERMS OF OPTION

         Each Option shall be evidenced by a written Option Agreement executed
by the Company and the Eligible Director which shall specify the Grant Date, the
number of shares of Common Stock subject to the Option, the Exercise Price and
shall also include or incorporate by reference the substance of all of the
following provisions and such other provisions consistent with this Plan as the
Board may determine:

         6.1 Term. The term of the Option shall be five (5) years from the Grant
Date of each Option, subject to earlier termination in accordance with Articles
VI and X of the Plan.

         6.2 Restriction on Exercise. No Option shall be exercisable until six
(6) months after the Grant Date, except in the case of the Eligible Director's
death or permanent disability, upon which events the Option will become
immediately exercisable. Thereafter, an Option, or any portion thereof, may be
exercised until the earlier of the expiration of the option's term or
termination of the Option in accordance with this Article VI.

         6.3 Exercise Price. The Exercise Price for each share of Common Stock
subject to an Option shall be the Fair Market Value of the Common Stock as
determined in Section 2.12 herein.

         6.4 Manner of Exercise. An option shall be exercised in accordance with
its terms, by delivery of a written notice of exercise to the Company and
payment of the full purchase price of the shares of Common Stock being
purchased. An Eligible Director may exercise an Option with respect to all or
less than all of the shares of Common Stock for which the Option may then be
exercised, but an eligible Director must exercise the Option in full shares of
Common Stock.

         6.5 Payment. The Purchase Price pursuant to an Option or portion
thereof, may be paid:

             (a) in United States dollars, in cash or by check, bank draft or 
money order payable to the Company; or

             (b) by delivery of shares of Common Stock owned by an Eligible 
Director which has an aggregate Fair Market Value on the date of exercise equal
to the purchase price, subject to the provisions of ss.16(b) of the Exchange Act
and the rules and regulations promulgated thereunder; or

             (c) to the extent authorized by the Board, or if specified in the
Option being exercised, by a promissory note from Optionee to the Company, upon
such terms and conditions determined by the Board and secured by the Common
Stock issuable upon exercise of the Option; or

             (d) by any combination of the above methods of payment.

         6.6 Transferability. No Option shall be transferable otherwise than by
will or the laws of descent and distribution, and an Option shall be exercisable
during the Eligible Director's lifetime only by the Eligible Director, his
guardian or legal representative.

         6.7 Termination of Membership on the Board. If an Eligible Director's
membership on the Board terminates for any reason, an Option held on the date of
termination may be exercised in whole or in part at any time within one (1) year
after the date of such termination (but in no event after the actual expiration
of the term of the Option) and shall thereafter terminate.

                                   ARTICLE VII

                        GOVERNMENT AND OTHER REGULATIONS

         7.1 Delivery of Common Stock. The obligation of the Company to issue or

         7.2 Holding of Stock After Exercise of Option. The Option Agreement
shall provide that the Eligible Director, by accepting such option, represents
and agrees, for the Eligible Director and his permitted transferees that none of
the shares of Common Stock purchased upon exercise of the Option shall be
acquired with a view to any sale, transfer or distribution of the Common Stock
in violation of the Securities Act of 1933, as amended (the "Act") and the
person exercising an Option shall furnish evidence satisfactory to that Company
to that effect, including an indemnification of the Company in the event of any
violation of the Act by such person.

                                  ARTICLE VIII

                                 WITHHOLDING TAX

         The Company may, in its discretion, require an Eligible Director to pay
to the Company, at the time of exercise of an Option an amount that the Company
deems necessary to satisfy its obligations, if any, to withhold federal, state
or local income or other taxes (which for purposes of this Article VIII includes
an Eligible Director's FICA obligation) incurred by reason of such exercise.
When the exercise of an Option does not give rise to the obligation to withhold
federal income taxes on the date of exercise, the Company may, in its
discretion, require an Eligible Director to place shares of Common Stock
received upon exercise of the Option in escrow for the benefit of the Company
until such time as federal income tax withholding is required on amounts
included in the Eligible Director's gross income as a result of the exercise of
an Option. At such time, the Company, in its discretion, may require an Eligible
Director to pay to the Company an amount that the Company deems necessary to
satisfy its obligation to withhold federal, state or local taxes incurred by
reason of the exercise of the Option, in which case the shares of Common Stock
will be released from escrow upon such payment by an Eligible Director.

                                   ARTICLE IX

                                   ADJUSTMENTS

         9.1 Proportionate Adjustments. If the outstanding shares of Common
Stock are increased, decreased, changed into or exchanged into a different
number or kind of shares of Common Stock or securities of the Company through
reorganization, recapitalization, reclassification, stock dividend, stock split,
reverse stock split or other similar transaction, an appropriate and
proportionate adjustment shall be made to the maximum number and kind of shares
of Common Stock as to which Options may be granted under this Plan. A
corresponding adjustment changing the number or kind of shares of Common Stock
allocated to unexercised Options or portions thereof, which shall have been
granted prior to any such change, shall likewise be made. Any such adjustment in
the outstanding Options shall be made without change in the Purchase Price
applicable to the unexercised portion of the Option with a corresponding
adjustment in the Exercise Price of the shares of Common Stock covered by the
Option. Notwithstanding the foregoing, there shall be no adjustment for the
issuance of shares of Common Stock on conversion of notes, preferred stock or
exercise of warrants or shares of Common Stock issued by the Board for such
consideration as the Board deems appropriate.

         9.2 Dissolution or Liquidation. Upon the dissolution or liquidation of
the Company, or upon a reorganization, merger or consolidation of the Company
with one or more corporations as a result of which the Company is not the
surviving corporation, or upon a sale of substantially all of the property or
more than 50% of the then outstanding shares of Common Stock of the Company to
another corporation, the Company shall give to each Eligible Director at the
time of adoption of the plan for liquidation, dissolution, merger or sale either
(1) a reasonable time thereafter within which to exercise the Option prior to
the effective date of such liquidation or dissolution, merger or sale, or (2)
the right to exercise the Option as to an equivalent number of shares of Common
Stock of the corporation succeeding the Company or acquiring its business by
reason of such liquidation, dissolution, merger, consolidation or
reorganization.

         The Plan shall be submitted for approval by the holders of the
outstanding voting stock of the Company within twelve (12) months from the date
the Plan is adopted by the Board; provided, however, that if such vote was not
solicited substantially in accordance with the rules and regulations, if any, in
effect under ss.14(a) of the Exchange Act, at the time of such vote, the Company
will furnish in writing to the holders of record of the securities entitled to
vote for the Plan substantially the same information concerning the Plan which
would be required by the rules and regulations in effect under ss.14(a) of the
Exchange Act, as if proxies to be voted with respect to the approval or
disapproval of the Plan were then being solicited, on or prior to the date of
the first annual meeting of security holders held subsequent to the later of (i)
the first registration of an equity security under ss.12 of the Exchange Act; or

The Plan shall be deemed approved by the holders of the outstanding voting stock
of the Company by the affirmative vote of the holders of a majority of the
voting shares of the Company represented and voting at a duly held meeting at
which a quorum is present. Any Options granted under the Plan prior to obtaining
such stockholder approval shall be granted under the conditions that the Options
so granted (i) shall not be exercisable prior to such approval, and (ii) shall
become null and void if such stockholder approval is not obtained.

                                  ARTICLE XIII

                                 RELOAD OPTIONS

         13.1 Reload Option. Whenever the Optionee holding any Option
outstanding under the Plan (including Reload Options granted under this Article
XIII) exercises the Option and makes payment of the Exercise Price pursuant to
Section 6.5(b) by tendering Common Stock previously held by the Optionee, then
the Company shall automatically grant a Reload Option for the number of shares
of Common Stock that is equal to the number of shares tendered by the Optionee
on payment of the Exercise Price of the Option being exercised.

         13.2 Reload Option Exercise Price. The Reload Option Exercise Price per
share shall be an amount equal to the Fair Market Value per share of the

Option shall expire, and the Reload Option shall no longer be exercisable, on
the later of (i) expiration date of the original surrendered Option, or (ii) one
year from the date of grant.

         13.4 Restriction on Exercise. Any Reload Option granted under this
Article XIII shall vest immediately, but shall not be exercisable until the end
of six months after the date of its issuance, except in the case of the death or

become immediately exercisable.

         13.5 Other Terms of Reload Options. All other terms of the Reload
Options granted hereunder shall be identical to the terms and conditions of the
original Option, the exercise of which gives rise to the grant of the Reload
Option.
