(g)  The description of the common stock of the Registrant contained in the
     Registrant's Registration Statement on Form 8-A (File No. 1-10288) filed on
     April 9, 1989, including all amendments and reports filed for the purpose
     of updating such description.

     All documents subsequently filed by the Registrant pursuant to Sections

filing of such documents.

Item 4.  Description of Securities.

Not required.

Item 5.  Interests of Named Experts and Counsel.

No material interests.

Item 6.  Indemnification of Directors and Officers.

     Section 145 of the Delaware General Corporation Law, as amended, provides
that a corporation may indemnify any person who was or is a party or is
threatened to be made a party to any threatened, pending or completed action,
suit or proceeding, whether civil, criminal or investigative (other than an
action by or in the right of the corporation) by reason 

                                      -2-
<PAGE>
 
of the fact that he is or was a director, officer, employee or agent of the
corporation, or is or was serving at the request of the corporation as a
director, officer, employee or agent of another corporation, partnership, joint
venture, trust or other enterprise, against expenses (including attorneys'
fees), judgments, fines and amounts paid in settlement actually and reasonably
incurred by him in connection with such action, suit or proceeding if he acted
in good faith and in a manner he reasonably believed to be in or not opposed to
the best interests of the corporation, and, with respect to any criminal action
or proceeding, had no reasonable cause to believe his conduct was unlawful.
Section 145 further provides that a corporation similarly may indemnify any such
person serving in any such capacity who was or is a party or is threatened to be
made a party to any threatened, pending or completed action or suit by or in the
right of the corporation to procure a judgment in its favor, against expenses
actually and reasonably incurred in connection with the defense or settlement of
such action or suit if he acted in good faith and in a manner he reasonably
believed to be in or not opposed to the best interests of the corporation and
except that no indemnification shall be made in respect of any claim, issue or
matter as to which such person shall have been adjudged to be liable to the
corporation unless and only to the extent that the Delaware Court of Chancery or
such other court in which such action or suit was brought shall determine upon
application that, despite the adjudication of liability but in view of all the
circumstances of the case, such person is fairly and reasonably entitled to
indemnity for such expenses which the Court of Chancery or such other court
shall deem proper.

        Section 102(b)(7) of the Delaware General Corporation Law, as amended,
permits a corporation to include in its certificate of incorporation a provision
eliminating or limiting the personal liability of a director to the corporation
or its stockholders for monetary damages for breach of fiduciary duty as a
director, provided that such provision shall not eliminate or limit the
liability of a director (i) for any breach of the director's duty of loyalty to
the corporation or its stockholders, (ii) for acts or omissions not in good
faith or which involve intentional misconduct or a knowing violation of law,
(ii) for acts or omissions not in good faith or which involve intentional
misconduct or a knowing violation of law, (iii) under Section 174 of the
Delaware General Corporation Law (relating to unlawful payment of dividends and
unlawful stock purchase and redemption), or (iv) for any transaction from which
the director derived an improper personal benefit.

        The Registrant's Restated Certificate of Incorporation, as amended,
provides that the Company's Directors shall not be liable to the Registrant or
its stockholders for monetary damages for breach of fiduciary duty as a
director, except to the extent that exculpation from liabilities is not
permitted under the Delaware General Corporation Law as in effect at the time
such liability is determined. The Restated Certificate of Incorporation, as
amended, further provides that the Registrant shall indemnify its directors and
officers to the full extent permitted by the law of the State of Delaware.

Item 9.  Undertakings.

     (a)  The undersigned Registrant hereby undertakes:

     (1)  To file, during any period in which offers or sales are being made, a
post-effective amendment to this registration statement:

     (i)  To include any prospectus required by Section 10(a)(3) of the
Securities Act;

     (ii) To reflect in the prospectus any facts or events arising after the
effective date of the registration statement (or the most recent post-effective
amendment thereof) which, individually or in the aggregate, represent a
fundamental change in the information set forth in the registration statement;

    (iii) To include any material information with respect to the plan of
distribution not previously disclosed in the registration statement or any
material change to such information in this registration statement;

         provided, however, that paragraphs (a)(1)(i) and (a)(1)(ii) above shall
not apply if the information required to be included in a post-effective
amendment by those paragraphs is contained in periodic reports filed by the
Registrant pursuant to Section 13 or Section 15(d) of the Exchange Act that are
incorporated by reference in the registration statement.

                                      -4-
<PAGE>
 
     (2)  That, for the purpose of determining any liability under the
Securities Act, each such post-effective amendment shall be deemed to be a new
registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.

     (3)  To remove from registration by means of a post-effective amendment any
of the securities being registered which remain unsold at the termination of the
offering.

     (b)  The undersigned Registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act, each filing of the
Registrant's annual report pursuant to Section 13(a) or Section 15(d) of the
Exchange Act (and where applicable, each filing of an employee benefit plan's
annual report pursuant to Section 15(d) of the Exchange Act) that is
incorporated by reference in the registration statement shall be deemed to be a
new registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.

     (c)  Insofar as indemnification for liabilities arising under the
Securities Act may be permitted to directors, officers and controlling persons
of the Registrant pursuant to the foregoing provisions, or otherwise, the
Registrant has been advised that in the opinion of the Securities and Exchange
Commission such indemnification is against public policy as expressed in the
Securities Act and is, therefore, unenforceable.  In the event that a claim for
indemnification against such liabilities (other than the payment by the
registrant of expenses incurred or paid by a director, officer, or controlling
person of the Registrant in the successful defense of any action, suit or
proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered, the Registrant will, unless in
the opinion of its counsel the matter has been settled by controlling precedent,
submit to a court of appropriate jurisdiction the question whether such
indemnification by it is against public policy as expressed in the Securities
Act and will be governed by the final adjudication of such issue.

Ladies and Gentlemen:

         This opinion is furnished to you in connection with a registration
statement on Form S-8 (the "Registration Statement") to be filed with the
Securities and Exchange Commission (the "Commission") under the Securities Act
of 1933, as amended, for the registration of 6,413 shares of common stock,
$0.01 par value per share (the "Shares"), of Cabletron Systems, Inc., a Delaware
corporation (the "Company"), issuable upon exercise of options assumed by the
Company that had previously been issued under The OASys Group, Inc. 1996 Stock
Option Plan (the "Plan").

         We have acted as counsel for the Company in connection with the
assumption of the Options and are familiar with the actions taken by the Company
in connection therewith. For purposes of this opinion we have examined the
Registration Statement, the Plan and such other documents as we have deemed
appropriate.

         Based upon the foregoing, we are of the opinion that (i) the Shares
have been duly authorized and (ii) the Shares, when issued and sold in
accordance with the terms of the Options and Plan, will have been validly issued
and will be fully paid and non-assessable.

         We hereby consent to your filing this opinion as an exhibit to the
Registration Statement.

                                  Very truly yours,

provisions of the Plan and, in the case of a Committee, the specific duties
delegated by the Board to such Committee, and subject to the approval of any
relevant authorities, including the approval, if required, of any stock exchange
upon which the Common Stock is listed, the Administrator shall have the
authority, in its discretion:

                           (i)      to determine the Fair Market Value of the
Common Stock, in accordance with Section 2(l) of the Plan;

                           (ii)     to select the Consultants and Employees to
whom Options may from time to time be granted hereunder;

                           (iii)    to determine whether and to what extent
Options are granted hereunder;

                           (iv)     to determine the number of shares of Common
Stock to be covered by each such award granted hereunder;

                           (viii)   to reduce the exercise price of any Option

and
<PAGE>
 
                           (ix)     to construe and interpret the terms of the
Plan and awards granted pursuant to the Plan.

                  (d) Effect of Administrator's Decision. All decisions,
                      ----------------------------------
determinations and interpretations of the Administrator shall be final and
binding on all Optionees and any other holders of any Options.

         5.       Eligibility.
                  -----------

                  (a) Nonstatutory Stock Options may be granted to Employees and
Consultants. Incentive Stock Options may be granted only to Employees. An
Employee or Consultant who has been granted an Option may, if otherwise
eligible, be granted additional Options.

                  (b) Each Option shall be designated in the written option
agreement as either an Incentive Stock Option or a Nonstatutory Stock Option.
However, notwithstanding such designation, to the extent that the aggregate Fair
Market Value of the Shares with respect to which Incentive Stock Options are
exercisable for the first time by the Optionee during any calendar year (under
all plans of the Company and any Parent or Subsidiary) exceeds $100,000, such
Options shall be treated as Nonstatutory Stock Options. For purposes of this
Section 5(b), Incentive Stock Options shall be taken into account in the order
in which they were granted. The Fair Market Value of the Shares shall be
determined as of the time the Option with respect to such Shares is granted.

                  (c) The Plan shall not confer upon any Optionee any right with
respect to continuation of employment or consulting relationship with the
Company, nor shall it interfere in any way with his or her right or the
Company's right to terminate his or her employment or consulting relationship at
any time, with or without cause.

         6.       Term of Plan. The Plan shall become effective upon its
                  ------------
adoption by the Board of Directors. It shall continue in effect for a term of
ten (10) years unless sooner terminated under Section 13 of the Plan.

         7.       Term of Option. The term of each Option shall be the term
                  --------------
stated in the Option Agreement; provided, however, that the term shall be no
more than ten (10) years from the date of grant thereof. However, in the case of
an Incentive Stock Option granted to an Optionee who, at the time the Option is
granted, owns stock representing more than ten percent (10%) of the voting power
of all classes of stock of the Company or any Parent or Subsidiary, the term of
the Option shall be five (5) years from the date of grant thereof or such
shorter term as may be provided in the Option Agreement.

         8.       Option Exercise Price and Consideration.
                  ---------------------------------------

                  (i) In the case of an Incentive Stock Option

                      (A) granted to an Employee who, at the time of the grant
of such Incentive Stock Option, owns stock representing more than ten percent
(10%) of the voting power of all classes of stock of the Company 

<PAGE>
 
or any Parent or Subsidiary, the per Share exercise price shall be no less than
110% of the Fair Market Value per Share on the date of grant.

                      (B) granted to any Employee other than an Employee
described in the preceding paragraph, the per Share exercise price shall be no
less than 100% of the Fair Market Value per Share on the date of grant.

                      (ii) In the case of a Nonstatutory Stock Option

                           (A) granted to a person who, at the time of the grant
of such Option, owns stock representing more than ten percent (10%) of the
voting power of all classes of stock of the Company or any Parent or Subsidiary,
the per Share exercise price shall be no less than 110% of the Fair Market Value
per Share on the date of the grant.

                           (B) granted to any person, the per Share exercise
price shall be no less than 85% of the Fair Market Value per Share on the date
of grant.

                  (b) The consideration to be paid for the Shares to be issued
upon exercise of an Option, including the method of payment, shall be determined
by the Administrator (and, in the case of an Incentive Stock Option, shall be
determined at the time of grant) and may consist entirely of (1) cash, (2)
check, (3) promissory note, (4) other Shares which (x) in the case of Shares
acquired upon exercise of an Option have been owned by the Optionee for more
than six months on the date of surrender and (y) have a Fair Market Value on the
date of surrender equal to the aggregate exercise price of the Shares as to
which said Option shall be exercised, (5) delivery of a properly executed
exercise notice together with such other documentation as the Administrator and
the broker, if applicable, shall require to effect an exercise of the Option and
delivery to the Company of the sale or loan proceeds required to pay the
exercise price, or (6) any combination of the foregoing methods of payment. In
making its determination as to the type of consideration to accept, the
Administrator shall consider if acceptance of such consideration may be
reasonably expected to benefit the Company.

         9.       Exercise of Option.
                  ------------------

                  (a) Procedure for Exercise; Rights as a Shareholder. Any
                      -----------------------------------------------
Option granted hereunder shall be exercisable at such times and under such
conditions as determined by the Administrator, including performance criteria
with respect to the Company and/or the Optionee, and as shall be permissible
under the terms of the Plan, but in no case at a rate of less than 20% per year
over five (5) years from the date the Option is granted.

                      An Option may not be exercised for a fraction of a
Share.

                      An Option shall be deemed to be exercised when written
notice of such exercise has been given to the Company in accordance with the
terms of the Option by the person entitled to exercise the Option and full
payment for the Shares with respect to which the Option is exercised has been
received by the Company. Full payment may, as authorized by the Administrator,
consist of any consideration and method of payment allowable under Section 8(b)
of the Plan. Until the issuance (as evidenced by the appropriate entry on the
books of the Company or of a duly authorized transfer agent of the Company) of
the stock certificate evidencing such Shares, no right to vote or receive
dividends or any other rights as a shareholder shall exist with respect to the
Optioned Stock, notwithstanding the exercise of the Option. 
<PAGE>
 
The Company shall issue (or cause to be issued) such stock certificate promptly
upon exercise of the Option. No adjustment will be made for a dividend or other
right for which the record date is prior to the date the stock certificate is
issued, except as provided in Section 11 of the Plan.

                      Exercise of an Option in any manner shall result in a
decrease in the number of Shares which thereafter may be available, both for
purposes of the Plan and for sale under the Option, by the number of Shares as
to which the Option is exercised.

                  (b) Termination of Employment or Consulting Relationship. In
                      ----------------------------------------------------
the event of termination of an Optionee's Continuous Status as an Employee or
Consultant (but not in the event of an Optionee's change of status from Employee
to Consultant (in which case an Employee's Incentive Stock Option shall
automatically convert to a Nonstatutory Stock Option on the date three (3)
months and one day from the date of such change of status) or from Consultant to
Employee), such Optionee may, but only within such period of time as is
determined by the Administrator and set forth in the Notice of Grant, of at
least thirty (30) days, with such determination in the case of an Incentive
Stock Option not exceeding three (3) months after the date of such termination
(but in no event later than the expiration date of the term of such Option as
set forth in the Option Agreement), exercise his or her Option to the extent
that Optionee was entitled to exercise it at the date of such termination. To
the extent that Optionee was not entitled to exercise the Option at the date of
such termination, or if Optionee does not exercise such Option to the extent so
entitled within the time specified herein, the Option shall terminate.

                  (c) Disability of Optionee. In the event of termination of an
                      ----------------------
Optionee's Continuous Status as an Employee or Consultant as a result of his or
her disability, Optionee may, but only within six (6) months from the date of
such termination (and in no event later than the expiration date of the term of
such Option as set forth in the Option Agreement), exercise the Option to the
extent otherwise entitled to exercise it at the date of such termination;
provided, however, that if such disability is not a "disability" as such term is
defined in Section 22(e)(3) of the Code, in the case of an Incentive Stock
Option such Incentive Stock Option shall automatically convert to a Nonstatutory
Stock Option one day following the end of the exercise period determined
pursuant to Section 9(b) of the Plan. To the extent that Optionee is not
entitled to exercise the Option at the date of termination, or if Optionee does
not exercise such Option to the extent so entitled within the time specified
herein, the Option shall terminate, and the Shares covered by such Option shall
revert to the Plan.

                  (d) Death of Optionee. In the event of the death of an
                      -----------------
Optionee, the Option may be exercised at any time within six (6) months
following the date of death (but in no event later than the expiration of the
term of such Option as set forth in the Notice of Grant), by the Optionee's
estate or by a person who acquired the right to exercise the Option by bequest
or inheritance, but only to the extent that the Optionee was entitled to
exercise the Option at the date of death. If, at the time of death, the Optionee
was not entitled to exercise his or her entire Option, the Shares covered by the
unexercisable portion of the Option shall immediately revert to the Plan. If,
after death, the Optionee's estate or a person who acquired the right to
exercise the Option by bequest or inheritance does not exercise the Option
within the time specified herein, the Option shall terminate, and the Shares
covered by such Option shall revert to the Plan.

                  (e) Rule 16b-3. Options granted to persons subject to Section
                      ----------
16(b) of the Exchange Act must comply with Rule 16b-3 and shall contain such
additional conditions or restrictions as may be required thereunder to qualify
for the maximum exemption from Section 16 of the Exchange Act with respect to
Plan transactions.
<PAGE>
 
                  (f) Buyout Provisions. The Administrator may at any time offer
                      -----------------
to buy out for a payment in cash or Shares, an Option previously granted, based
on such terms and conditions as the Administrator shall establish and
communicate to the Optionee at the time that such offer is made.

         10. Non-Transferability of Options. Options may not be sold, pledged,
             ------------------------------  
assigned, hypothecated, transferred, or disposed of in any manner other than by
will or by the laws of descent or distribution and may be exercised, during the
lifetime of the Optionee, only by the Optionee.

         11. Adjustments Upon Changes in Capitalization or Merger.
             ----------------------------------------------------
             
             (a) Changes in Capitalization. Subject to any required action
                 -------------------------
by the shareholders of the Company, the number of shares of Common Stock covered
by each outstanding Option, and the number of shares of Common Stock which have
been authorized for issuance under the Plan but as to which no Options have yet
been granted or which have been returned to the Plan upon cancellation or
expiration of an Option, as well as the price per share of Common Stock covered
by each such outstanding Option, shall be proportionately adjusted for any
increase or decrease in the number of issued shares of Common Stock resulting
from a stock split, reverse stock split, stock dividend, combination or
reclassification of the Common Stock, or any other increase or decrease in the
number of issued shares of Common Stock effected without receipt of
consideration by the Company; provided, however, that conversion of any
convertible securities of the Company shall not be deemed to have been "effected
without receipt of consideration." Such adjustment shall be made by the
Administrator, whose determination in that respect shall be final, binding and
conclusive. Except as expressly provided herein, no issuance by the Company of
shares of stock of any class, or securities convertible into shares of stock of
any class, shall affect, and no adjustment by reason thereof shall be made with
respect to, the number or price of shares of Common Stock subject to an Option.

             (b) Dissolution or Liquidation. In the event of the proposed
                 --------------------------
dissolution or liquidation of the Company, the Administrator shall notify the
Optionee at least fifteen (15) days prior to such proposed action. To the extent
it has not been previously exercised, the Option will terminate immediately
prior to the consummation of such proposed action.

             (c) Merger. In the event of a merger of the Company with or
                 ------
into another corporation, the Option may be assumed or an equivalent option may
be substituted by such successor corporation or a parent or subsidiary of such
successor corporation. If, in such event, the Option is not assumed or
substituted, the Option shall terminate as of the date of the closing of the
merger. For the purposes of this paragraph, the Option shall be considered
assumed if, following the merger, the option confers the right to purchase, for
each Share of Optioned Stock subject to the Option immediately prior to the
merger, the consideration (whether stock, cash, or other securities or property)
received in the merger by holders of Common Stock for each Share held on the
effective date of the transaction (and if holders were offered a choice of
consideration, the type of consideration chosen by the holders of a majority of
the outstanding Shares); provided, however, that if such consideration received
in the merger was not solely common stock of the successor corporation or its
Parent, the Administrator may, with the consent of the successor corporation,
provide for the consideration to be received upon the exercise of the Option for
each Share of Optioned Stock subject to the Option to be solely common stock of
the successor corporation or its Parent equal in fair market value to the per
share consideration received by holders of Common Stock in the merger.
<PAGE>
 
         12. Time of Granting Options. The date of grant of an Option shall, for
             ------------------------
all purposes, be the date on which the Administrator makes the determination
granting such Option, or such other date as is determined by the Board. Notice
of the determination shall be given to each Employee or Consultant to whom an
Option is so granted within a reasonable time after the date of such grant.

         13. Amendment and Termination of the Plan.
             -------------------------------------

             (a) Amendment and Termination. The Board may at any time
                 -------------------------
amend, alter, suspend or discontinue the Plan, but no amendment, alteration,
suspension or discontinuation shall be made which would impair the rights of any
Optionee under any grant theretofore made, without his or her consent. In
addition, to the extent necessary and desirable to comply with Rule 16b-3 under
the Exchange Act or with Section 422 of the Code (or any other applicable law or
regulation, including the requirements of the NASD or an established stock
exchange), the Company shall obtain shareholder approval of any Plan amendment
in such a manner and to such a degree as required.

             (b) Effect of Amendment or Termination. Any such amendment or
                 ----------------------------------
termination of the Plan shall not affect Options already granted, and such
Options shall remain in full force and effect as if this Plan had not been
amended or terminated, unless mutually agreed otherwise between the Optionee and
the Administrator, which agreement must be in writing and signed by the Optionee
and the Company.

         14. Conditions Upon Issuance of Shares. Shares shall not be issued
             ----------------------------------
pursuant to the exercise of an Option unless the exercise of such Option and the
issuance and delivery of such Shares pursuant thereto shall comply with all
relevant provisions of law, including, without limitation, the Securities Act of
1933, as amended, the Exchange Act, the rules and regulations promulgated
thereunder, and the requirements of any stock exchange upon which the Shares may
then be listed, and shall be further subject to the approval of counsel for the
Company with respect to such compliance.

             As a condition to the exercise of an Option, the Company may
require the person exercising such Option to represent and warrant at the time
of any such exercise that the Shares are being purchased only for investment and
without any present intention to sell or distribute such Shares if, in the
opinion of counsel for the Company, such a representation is required by any of
the aforementioned relevant provisions of law.

         15. Reservation of Shares. The Company, during the term of this Plan,
             ---------------------
will at all times reserve and keep available such number of Shares as shall be
sufficient to satisfy the requirements of the Plan.

                  The inability of the Company to obtain authority from any
regulatory body having jurisdiction, which authority is deemed by the Company's
counsel to be necessary to the lawful issuance and sale of any Shares hereunder,
shall relieve the Company of any liability in respect of the failure to issue or
sell such Shares as to which such requisite authority shall not have been
obtained.

         16. Agreements. Options shall be evidenced by written agreements in
             ----------
such form as the Administrator shall approve from time to time.
<PAGE>
 
         17. Shareholder Approval. Continuance of the Plan shall be subject to
             --------------------
approval by the shareholders of the Company within twelve (12) months before or
after the date the Plan is adopted. Such shareholder approval shall be obtained
in the degree and manner required under Applicable Laws and the rules of any
stock exchange upon which the Common Stock is listed.

         18. Information to Optionees and Purchasers. The Company shall provide
             ---------------------------------------
to each Optionee, not less frequently than annually, copies of annual financial
statements. The Company shall also provide such statements to each individual
who acquires Shares pursuant to the Plan while such individual owns such Shares.
The Company shall not be required to provide such statements to key employees
whose duties in connection with the Company assure their access to equivalent
information.

II.  AGREEMENT
     ---------

         1.       Grant of Option. The OASys Group, Inc. (the "Company"), hereby
                  ---------------
grants to the Optionee named in the Notice of Grant (the "Optionee"), an option
(the "Option") to purchase the total number of shares of Common Stock (the
"Shares") set forth in the Notice of Grant, at the exercise price per share set
forth in the Notice of Grant (the "Exercise Price") subject to the terms,
definitions and provisions of the 1996 Stock Option Plan (the "Plan") adopted by
the Company, which is incorporated herein by reference.

                  If designated in the Notice of Grant as an Incentive Stock
Option ("ISO"), this Option is intended to qualify as an ISO as defined in
Section 422 of the Code. However, if this Option is intended to be an ISO, to
the extent that it exceeds the $100,000 rule of Code Section 422(d) it shall be
treated as a Nonstatutory Stock Option ("NSO").

         2.       Exercise of Option. This Option shall be exercisable during
                  ------------------
its term in accordance with the provisions of Section 9 of the Plan as follows:

                  (i)   Right to Exercise.
                        -----------------

                         (a)   Subject to subsections 2(i)(b) through 2(i)(e)
below, this option may be exercised in whole or in part at any time. Vested
Shares shall not be subject to the Company's repurchase right (as set forth in
the Restricted Stock Purchase Agreement, attached hereto as Exhibit C-1).

                         (b)   As a condition to exercising this Option for
unvested Shares, the Optionee must execute the Restricted Stock Purchase
Agreement.

                         (c)   This Option may not be exercised for a fraction
of a Share.

                         (d)   In the event of Optionee's death, disability or
other termination of the employment or consulting relationship, the
exercisability of the Option is governed by Sections 6, 7 and 8 below, subject
to the limitation contained in subsection 2(i)(e).

                         (e)   In no event may this Option be exercised after
the date of expiration of the term of this Option as set forth in the Notice of
Grant.

                  (ii)  Method of Exercise. This Option shall be exercisable by
                        ------------------
written notice (in the form attached as Exhibit A) which shall state the
election to exercise the Option, the number of Shares in respect of which the
Option is being exercised, and such other representations and agreements with
respect to such shares of Common Stock as may 
<PAGE>
 
be required by the Company pursuant to the provisions of the Plan. Such written
notice shall be signed by the Optionee and, together with an executed copy of
the Restricted Stock Purchase Agreement, if applicable, shall be delivered in
person or by certified mail to the Secretary of the Company. The written notice
and Restricted Stock Purchase Agreement shall be accompanied by payment of the
Exercise Price. This Option shall be deemed to be exercised upon receipt by the
Company of such written notice and Restricted Stock Purchase Agreement
accompanied by the Exercise Price.

                  No Shares shall be issued pursuant to the exercise of an
Option unless such issuance and such exercise shall comply with all relevant
provisions of law and the requirements of any stock exchange upon which the
Shares may then be listed. Assuming such compliance, for income tax purposes the
Shares shall be considered transferred to the Optionee on the date on which the
Option is exercised with respect to such Shares.

            3. Optionee's Representations. In the event the Shares purchasable
               --------------------------
pursuant to the exercise of this Option have not been registered under the
Securities Act of 1933, as amended, at the time this Option is exercised,
Optionee shall, if required by the Company, concurrently with the exercise of
all or any portion of this Option, deliver to the Company his or her Investment
Representation Statement in the form attached hereto as Exhibit B, and shall
read the applicable rules of the Commissioner of Corporations attached to such
Investment Representation Statement.

            4. Lock-Up Period. Optionee hereby agrees that if so requested by
               --------------
the Company or any representative of the underwriters (the "Managing
Underwriter") in connection with any registration of the offering of any
securities of the Company under the Securities Act, Optionee shall not sell or
otherwise transfer any Shares or other securities of the Company during the
180-day period (or such longer period as may be requested in writing by the
Managing Underwriter and agreed to in writing by the Company) (the "Market
Standoff Period") following the effective date of a registration statement of
the Company filed under the Securities Act; provided, however, that such
restriction shall apply only to the first registration statement of the Company
to become effective under the Securities Act that includes securities to be sold
on behalf of the Company to the public in an underwritten public offering under
the Securities Act. The Company may impose stop-transfer instructions with
respect to securities subject to the foregoing restrictions until the end of
such Market Standoff Period.

            5. Method of Payment. Payment of the Exercise Price shall be by
               -----------------
any of the following, or a combination thereof, at the election of the Optionee:

               (i)   cash; or

               (ii)  check; or

               (iii) surrender of other shares of Common Stock of the Company
which (A) in the case of Shares acquired pursuant to the exercise of a Company
option, have been owned by the Optionee for more than six (6) months on the date
of surrender, and (B) have a Fair Market Value on the date of surrender equal to
the Exercise Price of the Shares as to which the Option is being exercised; or

               (iv)  to the extent permitted by the Administrator, delivery of a
properly executed exercise notice together with such other documentation as the
Administrator and the broker, if applicable, shall require to effect an exercise
of the Option and delivery to the Company of the sale or loan proceeds required
to pay the Exercise Price; or
<PAGE>
 
                (v)   full recourse promissory note, in the form attached hereto
as Exhibit C-6. Such note shall bear interest at the Mid-Term AFR rate for semi-
annual compounding periods, and shall be due and payable on the third
anniversary of the making of the note.

            6.  Restrictions on Exercise. This Option may not be exercised until
                ------------------------
such time as the Plan has been approved by the shareholders of the Company, or
if the issuance of such Shares upon such exercise or the method of payment of
consideration for such shares would constitute a violation of any applicable
federal or state securities or other law or regulation, including any rule under
Part 207 of Title 12 of the Code of Federal Regulations ("Regulation G") as
promulgated by the Federal Reserve Board. As a condition to the exercise of this
Option, the Company may require Optionee to make any representation and warranty
to the Company as may be required by any applicable law or regulation.

            7.  Termination of Relationship. In the event an Optionee's
                ---------------------------
Continuous Status as an Employee or Consultant terminates, Optionee may, to the
extent the Option was vested at the date of such termination (the "Termination
Date"), exercise this Option during the Termination Period set out in the Notice
of Grant. To the extent that Optionee was not vested in this Option at the date
of such termination, or if Optionee does not exercise this Option within the
time specified herein, the Option shall terminate.

            8.  Disability of Optionee. Notwithstanding the provisions of 
                ----------------------
Section 6 above, in the event of termination of an Optionee's Continuous Status
as an Employee or Consultant as a result of his or her disability, Optionee may,
but only within six (6) months from the date of such termination (and in no
event later than the expiration date of the term of such Option as set forth in
the Stock Option Agreement), exercise the Option to the extent the Option was
vested at the date of such termination; provided, however, that if such
disability is not a "disability" as such term is defined in Section 22(e)(3) of
the Code, in the case of an ISO such ISO shall cease to be treated as an ISO and
shall be treated for tax purposes as an NSO on the thirty-first (31st) day
following such termination. To the extent that Optionee is not vested in the
Option at the date of termination, or if Optionee does not exercise such Option
within the time specified herein, the Option shall terminate, and the Shares
covered by such Option shall revert to the Plan.

            9.  Death of Optionee. In the event of termination of Optionee's
                -----------------
Continuous Status as an Employee or Consultant as a result of the death of
Optionee, the Option may be exercised at any time within six (6) months
following the date of death (but in no event later than the date of expiration
of the term of this Option as set forth in Section 10 below), by Optionee's
estate or by a person who acquires the right to exercise the Option by bequest
or inheritance, but only to the extent the Option was vested at the date of
death. To the extent that Optionee is not vested in the Option at the date of
death, or if the Option is not exercised within the time specified herein, the
Option shall terminate, and the Shares covered by such Option shall revert to
the Plan.

            10. Non-Transferability of Option. This Option may not be
                -----------------------------
transferred in any manner otherwise than by will or by the laws of descent or
distribution and may be exercised during the lifetime of Optionee only by
Optionee. The terms of this Option shall be binding upon the executors,
administrators, heirs, successors and assigns of the Optionee.

            11. Term of Option. This Option may be exercised only within the
                --------------
term set out in the Notice of Grant, and may be exercised during such term only
in accordance with the Plan and the terms of this Option.

            12. Tax Consequences. Set forth below is a brief summary as of the
                ----------------
date of this Option of some of the federal tax consequences of exercise of this
Option and disposition of the Shares. THIS SUMMARY IS NECESSARILY 
<PAGE>
 
INCOMPLETE, AND THE TAX LAWS AND REGULATIONS ARE SUBJECT TO CHANGE. OPTIONEE
SHOULD CONSULT A TAX ADVISER BEFORE EXERCISING THIS OPTION OR DISPOSING OF THE
SHARES.

                  (i)   Exercise of ISO. If this Option qualifies as an ISO,
                        ---------------
there will be no regular federal income tax liability upon the exercise of the
Option, although the excess, if any, of the Fair Market Value of the Shares on
the date of exercise over the Exercise Price will be treated as an adjustment to
the alternative minimum tax for federal tax purposes and may subject the
Optionee to the alternative minimum tax in the year of exercise.

                  (ii)  Exercise of ISO Following Disability. If the Optionee's
                        ------------------------------------
Continuous Status as an Employee or Consultant terminates as a result of
disability that is not total and permanent disability as defined in Section
22(e)(3) of the Code, to the extent permitted on the date of termination, the
Optionee must exercise an ISO within one month of such termination for the ISO
to be qualified as an ISO.

                  (iii) Exercise of NSO. There may be a regular federal income
                        ---------------
tax liability upon the exercise of an NSO. The Optionee will be treated as
having received compensation income (taxable at ordinary income tax rates) equal
to the excess, if any, of the fair market value of the Shares on the date of
exercise over the Exercise Price. If Optionee is an Employee, the Company will
be required to withhold from Optionee's compensation or collect from Optionee
and pay to the applicable taxing authorities an amount equal to a percentage of
this compensation income at the time of exercise. If the Optionee is subject to
Section 16 of the Exchange Act, then the date of income recognition may be
deferred for up to six months.

                  (iv)  Disposition of Shares. In the case of an NSO, if Shares
                        ---------------------
are held for at least one year, any gain realized on disposition of the Shares
will be treated as long-term capital gain for federal income tax purposes. In
the case of an ISO, if Shares transferred pursuant to the Option are held for at
least one year after exercise and are disposed of at least two years after the
date of grant, any gain realized on disposition of the Shares will also be
treated as long-term capital gain for federal income tax purposes. If Shares
purchased under an ISO are disposed of within such one-year period or within two
years after the date of grant, any gain realized on such disposition will be
treated as compensation income (taxable at ordinary income rates) to the extent
of the difference between the Exercise Price and the lesser of (1) the fair
market value of the Shares on the date of exercise, or (2) the sale price of the
Shares.

                  (v)   Notice of Disqualifying Disposition of ISO Shares. If
                        -------------------------------------------------
the Option granted to Optionee herein is an ISO, and if Optionee sells or
otherwise disposes of any of the Shares acquired pursuant to the ISO on or
before the later of (1) the date two years after the date of grant, or (2) the
date one year after the date of exercise, the Optionee shall immediately notify
the Company in writing of such disposition. Optionee agrees that Optionee may be
subject to income tax withholding by the Company on the compensation income
recognized by the Optionee.

                  (vi)  Section 83(b) Election for Unvested Shares Purchased
                        ----------------------------------------------------
Pursuant to Nonqualified Stock Options. With respect to the exercise of a
- --------------------------------------
nonqualified stock option for unvested Shares, an election may be filed by the
Optionee with the Internal Revenue Service within 30 days of the purchase of the
                                           --------------
Shares, electing pursuant to Section 83(b) of the Code to be taxed currently on
any difference between the purchase price of the Shares and their Fair Market
Value on the date of purchase. This will result in a recognition of taxable
income to the Optionee on the date of exercise, measured by the excess, if any,
of the fair market value of the Shares, at the time the Option is exercised over
the purchase price for the Shares. Absent such an election, taxable income will
be measured and recognized by Optionee at the time or times on which the
Company's Repurchase Option lapses. Optionee is strongly encouraged to seek the
advice of his or her own tax consultants in connection with the purchase of the
Shares and the advisability of filing of the Election under Section 
<PAGE>
 
83(b) and similar tax provisions. A form of Election under Section 83(b) is
attached hereto as Exhibit C-5 for reference.

                  (vii) Section 83(b) Election for Unvested Shares Purchased
                        ----------------------------------------------------
Pursuant to Incentive Stock Options. With respect to the exercise of an
- -----------------------------------
incentive stock option for unvested Shares, an election may be filed by the
Optionee with the Internal Revenue Service within 30 days of the purchase of the
                                           --------------
Shares, electing pursuant to Section 83(b) of the Code to be taxed currently on
any difference between the purchase price of the Shares and their Fair Market
Value on the date of purchase for alternative minimum tax purposes. This will
result in a recognition of income to the Optionee on the date of exercise, for
alternative minimum tax purposes, measured by the excess, if any, of the fair
market value of the Shares, at the time the option is exercised, over the
purchase price for the Shares. Absent such an election, alternative minimum
taxable income will be measured and recognized by Optionee at the time or times
on which the Company's Repurchase Option lapses. Optionee is strongly encouraged
to seek the advice of his or her tax consultants in connection with the purchase
of the Shares and the advisability of filing of the Election under Section 83(b)
and similar tax provisions. A form of Election under Section 83(b) for
alternative minimum tax purposes is attached hereto as Exhibit C-6 for
reference.

            OPTIONEE ACKNOWLEDGES THAT IT IS OPTIONEE'S SOLE RESPONSIBILITY AND
NOT THE COMPANY'S TO FILE TIMELY THE ELECTION UNDER SECTION 83(b), EVEN IF
OPTIONEE REQUESTS THE COMPANY OR ITS REPRESENTATIVE TO MAKE THIS FILING ON
OPTIONEE'S BEHALF.

                             The OASys Group, Inc.


                             By: 
                                 -------------------------------
<PAGE>
 
            OPTIONEE ACKNOWLEDGES AND AGREES THAT THE VESTING OF SHARES PURSUANT
TO THE OPTION HEREOF IS EARNED ONLY BY CONTINUING CONSULTANCY OR EMPLOYMENT AT
THE WILL OF THE COMPANY (NOT THROUGH THE ACT OF BEING HIRED, BEING GRANTED THIS
OPTION OR ACQUIRING SHARES HEREUNDER). OPTIONEE FURTHER ACKNOWLEDGES AND AGREES
THAT NOTHING IN THIS AGREEMENT, NOR IN THE COMPANY'S STOCK OPTION PLAN WHICH IS
INCORPORATED HEREIN BY REFERENCE, SHALL CONFER UPON OPTIONEE ANY RIGHT WITH
RESPECT TO CONTINUATION OF EMPLOYMENT OR CONSULTANCY BY THE COMPANY, NOR SHALL
IT INTERFERE IN ANY WAY WITH OPTIONEE'S RIGHT OR THE COMPANY'S RIGHT TO
TERMINATE OPTIONEE'S EMPLOYMENT OR CONSULTANCY AT ANY TIME, WITH OR WITHOUT
CAUSE.

            Optionee acknowledges receipt of a copy of the Plan and represents
that he is familiar with the terms and provisions thereof, and hereby accepts
this Option subject to all of the terms and provisions thereof. Optionee has
reviewed the Plan and this Option in their entirety, has had an opportunity to
obtain the advice of counsel prior to executing this Option and fully
understands all provisions of the Option. Optionee hereby agrees to accept as
binding, conclusive and final all decisions or interpretations of the
Administrator upon any questions arising under the Plan or this Option. Optionee
further agrees to notify the Company upon any change in the residence address
indicated below.

combination thereof within 30 days after receipt of the Notice or in the manner
and at the times set forth in the Notice.

               (e) Holder's Right to Transfer. If all of the Shares proposed in

               ----------------
adverse tax consequences as a result of Optionee's purchase or disposition of
the Shares. Optionee represents that Optionee has consulted with any tax

disposition of the Shares and that Optionee is not relying on the Company for
any tax advice.

                      INVESTMENT REPRESENTATION STATEMENT

OPTIONEE  :

COMPANY   :  THE OASYS GROUP, INC.

SECURITY  :  COMMON STOCK

AMOUNT    :

DATE      :

In connection with the purchase of the above-listed Securities, the undersigned
Optionee represents to the Company the following:

                  (a) Optionee is aware of the Company's business affairs and
financial condition and has acquired sufficient information about the Company to
reach an informed and knowledgeable decision to acquire the Securities. Optionee
is acquiring these Securities for investment for Optionee's own account only and
not with a view to, or for resale in connection with, any "distribution" thereof
within the meaning of the Securities Act of 1933, as amended (the "Securities
Act").

                  (b) Optionee acknowledges and understands that the Securities
constitute "restricted securities" under the Securities Act and have not been
registered under the Securities Act in reliance upon a specific exemption
therefrom, which exemption depends upon, among other things, the bona fide
nature of Optionee's investment intent as expressed herein. In this connection,
Optionee understands that, in the view of the Securities and Exchange
Commission, the statutory basis for such exemption may be unavailable if
Optionee's representation was predicated solely upon a present intention to hold
these Securities for the minimum capital gains period specified under tax
statutes, for a deferred sale, for or until an increase or decrease in the
market price of the Securities, or for a period of one year or any other fixed
period in the future. Optionee further understands that the Securities must be
held indefinitely unless they are subsequently registered under the Securities
Act or an exemption from such registration is available. Optionee further
acknowledges and understands that the Company is under no obligation to register
the Securities. Optionee understands that the certificate evidencing the
Securities will be imprinted with a legend which prohibits the transfer of the
Securities unless they are registered or such registration is not required in
the opinion of counsel satisfactory to the Company, a legend prohibiting their
transfer without the consent of the Commissioner of Corporations of the State of
California and any other legend required under applicable state securities laws.

                  (c) Optionee is familiar with the provisions of Rule 701 and
Rule 144, each promulgated under the Securities Act, which, in substance, permit
limited public resale of "restricted securities" acquired, directly or
indirectly from the issuer thereof, in a non-public offering subject to the
satisfaction of certain conditions. Rule 701 provides that if the issuer
qualifies under Rule 701 at the time of the grant of the Option to the Optionee,
the exercise will be exempt from registration under the Securities Act. In the
event the Company becomes subject to the reporting requirements of Section 13 or
15(d) of the Securities Exchange Act of 1934, ninety (90) days thereafter (or
such longer period as any market stand-off agreement may require) the Securities
exempt under Rule 701 may be resold, subject to the satisfaction of certain of
the conditions specified by Rule 144, including: (1) the resale being made
through a broker in an unsolicited
<PAGE>
 
"broker's transaction" or in transactions directly with a market maker (as said
term is defined under the Securities Exchange Act of 1934); and, in the case of
an affiliate, (2) the availability of certain public information about the
Company, (3) the amount of Securities being sold during any three month period
not exceeding the limitations specified in Rule 144(e), and (4) the timely
filing of a Form 144, if applicable.

            In the event that the Company does not qualify under Rule 701 at the
time of grant of the Option, then the Securities may be resold in certain
limited circumstances subject to the provisions of Rule 144, which requires the
resale to occur not less than two years after the later of the date the
Securities were sold by the Company or the date the Securities were sold by an
affiliate of the Company, within the meaning of Rule 144; and, in the case of
acquisition of the Securities by an affiliate, or by a non-affiliate who
subsequently holds the Securities less than three years, the satisfaction of the
conditions set forth in sections (1), (2), (3) and (4) of the paragraph
immediately above.

                  (e) Optionee further understands that in the event all of the
applicable requirements of Rule 701 or 144 are not satisfied, registration under
the Securities Act, compliance with Regulation A, or some other registration
exemption will be required; and that, notwithstanding the fact that Rules 144
and 701 are not exclusive, the Staff of the Securities and Exchange Commission
has expressed its opinion that persons proposing to sell private placement
securities other than in a registered offering and otherwise than pursuant to
Rules 144 or 701 will have a substantial burden of proof in establishing that an
exemption from registration is available for such offers or sales, and that such
persons and their respective brokers who participate in such transactions do so
at their own risk. Optionee understands that no assurances can be given that any
such other registration exemption will be available in such event.

                  (f) Optionee understands that the certificate evidencing the
Securities will be imprinted with a legend which prohibits the transfer of the
Securities without the consent of the Commissioner of Corporations of
California. Optionee has read the applicable Commissioner's Rules with respect
to such restriction, a copy of which is attached.

                             Signature of Optionee:

  concerned;

       (8) to a broker-dealer licensed under the Code in a principal
  transaction, or as an underwriter or member of an underwriting syndicate or

  by the purchaser to the seller upon a sale of the security for which the
  Commissioner's written consent is obtained or under this rule not required;

       (10) by way of a sale qualified under Sections 25111, 25112, 25113 or

  transfer of the securities is restricted under this rule, (ii) delivers to
  each purchaser a copy of this rule, and (iii) advises the Commissioner of the
  name of each purchaser;

       (16) by a trustee to a successor trustee when such transfer does not
  involve a change in the beneficial ownership of the securities;

       (17) by way of an offer and sale of outstanding securities in an issuer
  transaction that is subject to the qualification requirement of Section 25110
  of the Code but exempt from that qualification requirement by subdivision (f)

Purchaser's personal representative, as the case may be, all of the Purchaser's
Unvested Shares as of the date of such termination at the price paid by the
Purchaser for such Shares (the "Repurchase Option"). Unvested Shares shall be
released from the Repurchase Option at such time and to such extent as such
shares would have vested under the Option Agreement had they not been purchased

its Repurchase Option by delivering personally or by registered mail, to
Purchaser (or his transferee or legal representative, as the case may be),
within ninety (90) days of the termination, a notice in writing indicating the
Company's intention to exercise the Repurchase Option and setting forth a date
for closing not later than thirty (30) days from the mailing of such notice. The
closing shall take place at the Company's office. At the closing, the holder of
the certificates for the Unvested Shares being transferred shall deliver the
stock certificate or certificates evidencing the Unvested Shares, and the
Company shall deliver the purchase price therefor.

       (c) At its option, the Company may elect to make payment for the Unvested
Shares to a bank selected by the Company. The Company shall avail itself of this
option by a notice in writing to Purchaser stating the name and address of the
bank, date of closing, and waiving the closing at the Company's office.

       (d) If the Company does not elect to exercise the Repurchase Option
conferred above by giving the requisite notice within ninety (90) days following
the termination, the Repurchase Option shall terminate.

Purchaser to the Company.

       (b) To insure the availability for delivery of Purchaser's Unvested

sell, assign and transfer unto the Company, such Unvested Shares, if any,
repurchased by the Company pursuant to the Repurchase Option and shall, upon
execution of this Agreement, deliver and deposit with the chief financial
officer of the Company, or such other person designated by the Company, the

assignment duly endorsed in blank, attached hereto as Exhibit C-2. The Unvested

escrow, pursuant to the Joint Escrow Instructions of the Company and Purchaser
attached as Exhibit C-3 hereto, until the Company exercises its purchase right
as provided in Section 1, until such Unvested Shares are vested, or until such
time as this Agreement no longer is in effect. Upon vesting of the Unvested
Shares, the escrow agent shall promptly deliver to the Purchaser the certificate
or certificates representing such Shares in the escrow agent's possession
belonging to the Purchaser, and the escrow agent shall be discharged of all
further obligations hereunder; provided, however, that the escrow agent shall
nevertheless retain such certificate or certificates as escrow agent if so
required pursuant to other restrictions imposed pursuant to this Agreement.

do or omit to do with respect to holding the Shares in escrow and while acting
in good faith and in the exercise of its judgment.

by Purchaser and shall acknowledge the same by signing a copy of this Agreement.

repurchase option set forth in the Agreement, the Company shall give to
Purchaser and you a written notice specifying the number of shares of stock to
be purchased, the purchase price, and the time for a closing hereunder at the
principal office of the Company. Purchaser and the Company hereby irrevocably
authorize and direct you to close the transaction contemplated by such notice in
accordance with the terms of said notice.

  2. At the closing, you are directed (a) to date the stock assignments
necessary for the transfer in question, (b) to fill in the number of shares
being transferred, and (c) to deliver same, together with the certificate

shares held or issued

of such compliance, notwithstanding any such order, judgment or decree being
subsequently reversed, modified, annulled, set aside, vacated or found to have

parties concerned or by a final order, decree or judgment of a court of
competent jurisdiction after the time for appeal has expired and no appeal has
been perfected, but you shall be under no duty whatsoever to institute or defend
any such proceedings.

shall be deemed effectively given upon personal delivery or upon deposit in the

                                   --------

  Pursuant to Pledgor's election to purchase Shares under the Option Agreement
dated ________ (the "Option"), between Pledgor and Pledgee under Pledgee's 1996

obligations thereunder are as set forth in Exhibit C-6 to the Option.

  NOW, THEREFORE, it is agreed as follows:

  1. Creation and Description of Security Interest. In consideration of the
     ---------------------------------------------
transfer of the Shares to Pledgor under the Option Agreement, Pledgor, pursuant
to the California Commercial Code, hereby pledges all of such Shares (herein
sometimes referred to as the "Collateral") represented by certificate number
______, duly endorsed in blank or with executed stock powers, and herewith
delivers said certificate to the Chief Financial Officer of Pledgee
("Pledgeholder"), who shall hold said certificate subject to the terms and
conditions of this Security Agreement.

  The pledged stock (together with an executed blank stock assignment for use in
transferring all or a portion of the Shares to Pledgee if, as and when required
pursuant to this Security Agreement) shall be held by the Pledgeholder as
security for the repayment of the Note, and any extensions or renewals thereof,
to be executed by Pledgor pursuant to the terms of the Option, and the
Pledgeholder shall not encumber or dispose of such Shares except in accordance
with the provisions of this Security Agreement.

  2. Pledgor's Representations and Covenants. To induce Pledgee to enter into
     ---------------------------------------
this Security Agreement, Pledgor represents and covenants to Pledgee, its
successors and assigns, as follows:

          -----------------------
Note secured hereby, together with interest thereon, at the time and in the
manner provided in the Note.

     b.   Encumbrances. The Shares are free of all other encumbrances, defenses
          ------------
and liens, and Pledgor will not further encumber the Shares without the prior
written consent of Pledgee.

     c.   Margin Regulations. In the event that Pledgee's Common Stock is now or
          ------------------
later becomes margin-listed by the Federal Reserve Board and Pledgee is
classified as a "lender" within the meaning of the regulations under Part 207 of
Title 12 of the Code of Federal Regulations ("Regulation G"), Pledgor agrees to
cooperate with Pledgee in making any amendments to the Note or providing any
additional collateral as may be necessary to comply with such regulations.

of principal and interest are made as they become due under the terms of the
Note, Pledgor shall have the right to vote all of the Shares pledged hereunder.

  4. Stock Adjustments. In the event that during the term of the pledge any

shares or other securities issued by reason of any such change shall be
delivered to and held by the Pledgee under the terms of this Security Agreement
in the same manner as the Shares originally pledged hereunder. In the event of

cooperate and execute such documents as are reasonable so as to provide for the
substitution of such Collateral and, upon such substitution, references to
"Shares" in this Security Agreement shall include the substituted shares of
capital stock of Pledgor as a result thereof.

  5. Options and Rights. In the event that, during the term of this pledge,
     ------------------
subscription Options or other rights or options shall be issued in connection
with the pledged Shares, such rights, Options and options shall be the property
of Pledgor and, if exercised by Pledgor, all new stock or other securities so
acquired by Pledgor as it relates to the pledged Shares then held by
Pledgeholder shall be immediately delivered to Pledgeholder, to be held under
the terms of this Security Agreement in the same manner as the Shares pledged.

  6. Default.  Pledgor shall be deemed to be in default of the Note and of this
     -------
Security Agreement in the event:

period of 10 days or more; or

     b.   Pledgor fails to perform any of the covenants set forth in the Option

pledge, substitute or otherwise dispose of all or any part of the Collateral

indebtedness secured hereby, at which time the remaining pledged stock shall be
promptly delivered to Pledgor, subject to the provisions for prior release of a
portion of the Collateral as provided in paragraph 7 above.

     ----------

         Form of Stock Option Assumption Agreement used in connection

                            CABLETRON SYSTEMS, INC.
                       STOCK OPTION ASSUMPTION AGREEMENT
                       ---------------------------------

OPTIONEE:

         STOCK OPTION ASSUMPTION AGREEMENT issued as of the ____ day of
February, 1997 by Cabletron Systems, Inc., a Delaware corporation ("Cabletron").

         WHEREAS, _____________ ("Optionee") holds one or more outstanding
options to purchase shares of the common stock of The OASys Group, Inc., a
California corporation ("OASys"), which were granted to Optionee under The OASys
Group, Inc. 1996 Stock Option Plan (the "Plan"), and are evidenced by a Stock
Option Agreement (the "Option Agreement") between OASys and Optionee.

         WHEREAS, OASys has this day been acquired by Cabletron through merger
of a wholly-owned Cabletron subsidiary, Small Cat, Inc. ("Merger Sub"), with and
into OASys (the "Merger") pursuant to the Agreement and Plan of Merger dated as
of November 26, 1996 by and among Cabletron, OASys and Merger Sub (the "Merger
Agreement").

         WHEREAS, the provisions of the Merger Agreement require Cabletron to
assume all obligations of OASys under all options outstanding under the Plan at
the consummation of the Merger and to issue to the holder of each outstanding
option a notice setting forth such holder's rights after consummation of the
Merger.

         WHEREAS, pursuant to the provisions of the Merger Agreement, the
exchange ratio in effect for the Merger is .04178 of a share of Cabletron common
stock ("Cabletron Stock") for each outstanding share of OASys common stock (the
"Exchange Ratio").

         WHEREAS, this Agreement is to become effective immediately upon the
consummation of the Merger (the "Effective Time") in order to reflect certain
adjustments to Optionee's outstanding options under the Plan which have become
necessary by reason of the assumption of those options by Cabletron in
connection with the Merger.

         NOW, THEREFORE, it is hereby agreed as follows:

         1. The number of shares of OASys common stock subject to the stock
options held by Optionee under the Plan immediately prior to the Effective Time
(the "OASys Options") and the exercise price payable per share are set forth in
Exhibit A hereto. Cabletron hereby assumes, as of the Effective Time, all the
duties and obligations of
<PAGE>
 
OASys under each of the OASys Options. In connection with such assumption, the
number of shares of Cabletron Stock purchasable under each OASys Option hereby
assumed and the exercise price payable thereunder have been adjusted to reflect
the Exchange Ratio at which shares of OASys common stock were converted into
shares of Cabletron Stock in consummation of the Merger. Accordingly, the number
of shares of Cabletron Stock subject to each OASys Option hereby assumed, and
the adjusted exercise price payable per share of Cabletron Stock under the
assumed OASys Option, shall be as indicated for that option in attached 
Exhibit B.

         2. The intent of the foregoing adjustments to each assumed OASys Option
is to assure that the spread between the aggregate fair market value of the
shares of Cabletron Stock purchasable under that option and the aggregate
exercise price as adjusted hereunder will, immediately after the consummation of
the Merger, equal the spread which existed, immediately prior to the Merger,
between the then aggregate fair market value of the OASys common stock subject
to the OASys Option and the aggregate exercise price in effect at such time
under the Option Agreement. Such adjustments are also designed to preserve, on a
per share basis immediately after the Merger, the same ratio of exercise price
per option share to fair market value per share which existed under the OASys
Option immediately prior to the Merger.

         3.  The following provisions shall govern each OASys Option hereby
assumed by Cabletron:

         - Unless the context otherwise requires, all references to the
"Company" in each Option Agreement and in the Plan (as incorporated into such
Option Agreement) shall mean Cabletron, all references to "Common Stock" shall
mean shares of Cabletron Stock, and all references to the "Committee" shall mean
the Incentive Compensation Committee of the Board of Directors of Cabletron.

         - The grant date and the expiration date of each assumed OASys Option
and all other provisions which govern either the exercisability or the
termination of the assumed OASys Option shall remain the same as set forth in
the Option Agreement applicable to that option and shall accordingly govern and
control Optionee's rights under this Agreement to purchase Cabletron Stock.

         - Each assumed OASys Option shall remain exercisable in accordance with
the same installment exercise schedule in effect under the applicable Option
Agreement immediately prior to the Effective Time, with the number of shares of
Cabletron Stock subject to each such installment adjusted to reflect the
Exchange Rate. Accordingly, no accelerated vesting of the OASys Options shall be
deemed to occur by reason of the Merger, and the grant date for each assumed
OASys Option shall accordingly remain the same as in effect under the applicable
Option Agreement immediately prior to the Merger.

         - For purposes of applying any and all provisions of the Option
Agreement relating to Optionee's status as an employee with the Company,
Optionee shall be deemed to continue in such employee status for so long as
Optionee renders services as an employee to Cabletron or any present or future
Cabletron subsidiary, including (without limitation) OASys. Accordingly, the
provisions of the Option Agreement governing the termination of the assumed
OASys Option upon the Optionee's cessation of employee status with OASys shall
hereafter be applied on the basis of the Optionee's cessation of employee status
with Cabletron and its subsidiaries, and each assumed OASys Option shall
accordingly terminate, within the designated time period in effect under the
Option Agreement for that option, following such cessation of employment with
Cabletron and its subsidiaries.
<PAGE>
 
         - The adjusted exercise price payable for the Cabletron Stock subject
to each assumed OASys Option shall be payable in any of the forms authorized
under the Option Agreement applicable to that option. For purposes of
determining the holding period of any shares of Cabletron Stock delivered in
payment of such adjusted exercise price, the period for which such shares were
held as OASys common stock prior to the Merger shall be taken into account.

         -  In order to exercise each assumed OASys Option, Optionee must
deliver to Cabletron a written notice of exercise in which the number of shares
of Cabletron Stock to be purchased thereunder must be indicated. The exercise
notice should be delivered to Cabletron at the following address:

         Cabletron Systems, Inc.

         35 Industrial Way
         Rochester, New Hampshire  03867
         Attention:  Edward Cortes

         4. Except to the extent specifically modified by this Stock Option
Assumption Agreement, all of the terms and conditions of each Option Agreement
as in effect immediately prior to the Merger shall continue in full force and
effect and shall not in any way be amended, revised or otherwise affected by
this Stock Option Assumption Agreement.

         IN WITNESS WHEREOF, Cabletron Systems, Inc. has caused this Stock
Option Assumption Agreement to be executed on its behalf by its duly-authorized
officer as of the ____ day of February, 1997.



         CABLETRON SYSTEMS, INC.
