Attention:  Michael S. Rosenblum, Esq.

Gentlemen:

         Reference is made to (i) that certain Securities Purchase Agreement
(the "Purchase Agreement"), dated March 8, 2000, by and among BIOGAN
INTERNATIONAL, INC., a Delaware corporation (the "Pledgor"), on the one hand,
certain of your clients, for whom you are acting as Agent (each, a "Pledgee"),
on the other hand, (ii) that certain 8% Secured Convertible Debenture (the
"Debenture"), dated February 28, 2000, in the principal amount of $2,035,000 by
Pledgor in favor of Pledgee, (iii) that certain Registration Rights Agreement
(the "Registration Rights Agreement"), dated March 8, 2000 by and among Pledgor
and Pledgee and (iv) those certain Warrants (the "Warrant") to purchase an
aggregate of 489,000 shares of the Pledgor's common stock issued to Pledgee (the
Purchase Agreement, the Debenture Agreement, the Registration Rights Agreement
and the Warrant are sometimes collectively referred to herein as the "Loan
Documents"). The Loan Documents contemplate, among other things, that the
obligations of Debtor thereunder are to be secured by a pledge of 28,800,000
shares of the Common Stock of the Debtor (the "Pledged Shares").

         1. PLEDGE.

         (a) Pledgor hereby pledges, grants a security interest in, mortgage,
assigns, transfers, delivers, sets over and confirms unto you as Agent for the
Pledgee, their successors and assigns, the Pledged Shares as collateral security
for the payment in full when due of all obligations of the Pledgor under the
Debenture and monetary obligations accruing under Article 2 (b) (i) and (ii) of
the Registration Rights Agreement (collectively, the "Obligations").

         (b) Whether or not stated with respect to each provision hereof, the
term "Pledgee" shall mean each respective Pledgee, in each case unless the
context otherwise requires.

         (c) Pledgor warrants and represents that, except as set forth in
Section 19 or as noted on the reverse side of the certificate(s) or
instrument(s) evidencing the Pledged Shares, there are no restrictions upon the
transfer of any of the Pledged Shares and that Pledgor has the right to transfer
the Pledged Shares free of any encumbrance.

<PAGE>

         (d) Pledgor hereby agrees promptly to pledge and deposit hereunder with
the Pledgee any stock or other securities declared as a dividend with respect to
or issued as a split of any Pledged Shares now or hereafter held in pledge
hereunder and any additional property hereafter pledged to the Pledgee by
Pledgor, whether taken in substitution for or in addition to the above-described
property. Such stock, other securities and property shall stand pledged and
assigned for the Obligations in the same manner as the property described in the
first paragraph hereof. (The Pledged Shares and all of the property described in
this paragraph is hereinafter called the "Collateral").

         2. REPRESENTATIONS, WARRANTIES AND COVENANTS OF THE PLEDGOR.

         Pledgor hereby represents, warrants and covenants to the Pledgee as
follows:

         (a) Except for the security interest and pledge hereunder, upon
delivery of the Collateral to the Pledgee, the Pledgor is, or to the extent that
certain of the Collateral is to be acquired after the date hereof, will be, the
sole owner of the Collateral free from any adverse lien, security interest or
encumbrance, and the Pledgor will defend the Collateral against all claims and
demands of all persons at any time claiming any interest therein.

         (b) The Pledgor will promptly pay any and all taxes, assessments and
governmental charges upon the Collateral prior to the date penalties are
attached thereto, except to the extent that such taxes, assessments and charges
shall be contested in good faith by the Pledgor.

         (c) The Pledgor will not sell or otherwise assign, transfer or dispose
of the Collateral or any interest therein without the prior written consent of
the Pledgees.

         (d) Except for the security interest and pledge hereunder, the Pledgor
will keep the Collateral free from any adverse lien, security interest or
encumbrance.

         (e) The Collateral is duly and validly issued, fully paid and
nonassessable, and each certificate evidencing Collateral is issued by the
Pledgor from its authorized and unissued shares.

         3. VOTING POWER, DIVIDENDS, ETC.

         (a) Unless and until an Event of Default (as defined below) has
occurred and except as provided below, the Pledged Shares shall be deemed to be
unissued shares of the Pledgor for the purpose of any and all exercises of
voting, consensual and other powers of ownership pertaining to the Pledged
Shares. With respect to any dividends (whether in stock or cash) or other
distributions to holders of shares of Pledgor's Common stock, the Pledgor shall
add to the Collateral, the proportionate amount of such dividend or other
distribution, as if the Pledged Shares were issued and outstanding.

                                       2
<PAGE>

         (b) Any provisions herein to the contrary notwithstanding, if any Event
of Default (or, as to subsection (ii) below, an event which, with the passage of
time and/or the giving of notice, or both, would constitute an Event of Default)
shall have occurred, then and whether or not any holder of the Obligations
exercises any available option to declare the Obligations due and payable or
seeks or pursues any other relief or remedy available to such holder under this
Pledge Agreement, or any agreement evidencing or securing any of the
Obligations,

                  (i) The Pledgees, or their respective nominee or nominees,
shall forthwith, without further act on the part of any person, have the sole
and exclusive right to exercise all voting, consensual and other powers of
ownership pertaining to the Collateral and shall exercise such powers in such
manner as the Pledgees, in their sole discretion, shall determine to be
necessary, appropriate or advisable, and, if the Pledgees shall so request in
writing, the Pledgor agrees to execute and deliver to the Pledgees such other
and additional powers, authorizations, proxies, dividends and such other
documents as the Pledgees may request to secure to the Pledgees' the rights,
powers and authorities intended to be conferred upon the Pledgees by this
subsection (b); and

                  (ii) All dividends and other distributions on the Collateral
shall be paid directly to the Pledgees and retained by it as part of the
Collateral, subject to the terms of this Pledge Agreement, and, if the Pledgees
shall so request in writing, the Pledgor agrees to execute and deliver to the
Pledgees appropriate additional dividend, distribution and other orders and
documents to that end.

Notwithstanding the foregoing or any other provision hereof, in no event shall
any Pledgee hold in excess of 9.99% of the shares of the Common Stock as such
limitation is more specifically provided for in Section 4.E. of the Debenture.

         4. SALE OF COLLATERAL AFTER AN EVENT OF DEFAULT.

         If any Event of Default shall have occurred, and the principal amount
of or any of the Obligations shall have been declared forthwith due and payable,
then, unless the Debenture and the Obligations shall have been paid in full, the
Pledgees may, in their sole discretion, without further demand, advertisement or
notice, except as expressly provided for in subsection (a) of this Section 4,
(i) apply the cash, if any, then held by it as collateral hereunder, for the
purposes and in the manner provided in Section 5 hereof, and (ii) if there shall
be no such cash or the cash so applied shall be insufficient to make in full all
payments provided in subsections (a) and (b) of Section 5 hereof,

                  (a) Sell the Collateral, or any part thereof, in one or more
sales, at public or private sale, conducted by any officer or agent of, or
auctioneer or attorney for, the Pledgees, at the Pledgees' place of business or
elsewhere, for cash, upon credit or future delivery, and at such price or prices
as the Pledgees shall, in their sole discretion, determine, and the Pledgees may
be the purchaser of any or all of the Collateral so sold. Upon any such sale the
Pledgees shall have the right to deliver, assign and transfer to the purchaser
thereof the Collateral so sold. Each purchaser (including, without limitation,
the Pledgees) at any such sale shall hold the Collateral so sold, absolutely

                                       3
<PAGE>

free from any claim or right of whatsoever kind, including, without limitation,
any equity or right of redemption of the Pledgor, which the Pledgor hereby
specifically waives, to the extent it may lawfully do so, and all rights of
redemption, stay or appraisal which Pledgor has or may have under any rule of
law or statute now existing or hereafter adopted. The Pledgees shall give the
Pledgor at least ten (10) days prior written notice of any such public or
private sale. Any such public sale shall be held at such time or times within
ordinary business hours as the Pledgees shall fix in the notice of such sale. At
any such public or private sale the Collateral may be sold in one lot as an
entirety or in separate parcels. The Pledgees shall not be obligated to make any
sale pursuant to any such notice. The Pledgees may, without notice or
publication, adjourn any public or private sale from time to time by
announcement at the time and place fixed for such sale, or any adjournment
thereof, and any such sale may be made at any time or place to which the same
may be so adjourned without further notice or publication. In case of any sale
of all or any part of the Collateral for credit or for future delivery, the
Collateral so sold may be retained by the Pledgees until the selling price is
paid by the purchaser thereof, but the Pledgees shall not incur any liability in
case of the failure of such purchaser to take up and pay for the Collateral so
sold, and in case of any such failure, such Collateral may again be sold under
and pursuant to the provisions hereof; or

                  (b) Proceed by a suit or suits at law or in equity to
foreclose upon this Pledge Agreement and sell the Collateral, or any portion
thereof, under a judgment or decree of a court or courts of competent
jurisdiction.

If at any time when the Pledgees shall determine to exercise their right to sell
all or any part of the Collateral pursuant to Section 4(a) hereof, such
Collateral or the part thereof to be sold shall not, for any reason whatsoever,
be effectively registered under the Securities Act of 1933, as from time to time
in effect (the "Securities Act"), the Pledgees, in their sole and absolute
discretion, are hereby expressly authorized to sell such Collateral or such part
thereof by private sale in such manner and under such circumstances as the
Pledgees may deem necessary or advisable in order that such sale may legally be
effected without such registration. Without limiting the generality of the
foregoing, in any such event the Pledgees, in their sole and absolute
discretion, (x) may proceed to make such private sale notwithstanding that a
registration statement for the purpose of registering such Collateral or such
part thereof shall have been filed under such Securities Act; (y) may approach
and negotiate with a restricted number of potential purchasers to effect such
sale; and (z) may restrict such sale to purchasers as to their number, nature of
business and investment intention, including, without limitation, to purchasers
each of whom will represent and agree to the satisfaction of the Pledgees that
such purchaser is purchasing for its own account, for investment, and not with a
view to the distribution or sale of such Collateral or part thereof, it being
understood that the Pledgees may require the Pledgor, and the Pledgor hereby
agrees upon the written request of the Pledgees, to cause: (i) a legend or
legends to be placed on the certificates to be delivered to such purchasers to
the effect that the Collateral represented thereby has not been registered under
the Securities Act and setting forth or referring to restrictions on the
transferability of such securities or (ii) the issuance of stop transfer
instructions to the transfer agent of any issuer (each an "Issuer") of such
securities, if any, with respect to the Collateral, or if the Issuer transfers
its own securities, a notation in the appropriate records of such Issuer, and
that the Pledgees may require to be obtained, and the Pledgor will cooperate
with the Pledgees in obtaining from the purchasers a signed written agreement
that the Collateral will not be sold without registration or other compliance
with the requirements of the Securities Act. In the event of any such sale, the
Pledgor does hereby consent and agree that the Pledgees shall incur no
responsibility or liability for selling all or any part of the Collateral at a
price which the Pledgees, in their sole and absolute discretion, may deem
reasonable under the circumstances, notwithstanding the possibility that a
substantially higher price might be realized if the sale were public and
deferred until after registration under the Securities Act.

                                       4
<PAGE>

         The Pledgees, as attorney-in-fact pursuant to Section 6 hereof, may, in
the name and stead of the Pledgor, make and execute all conveyances, assignments
and transfers of the Collateral sold pursuant to this Section 4. The Pledgor
shall, if so requested by the Pledgees, ratify and confirm any sale or sales by
executing and delivering to the Pledgees, or to such purchaser or purchasers,
all such instruments as may, in the judgment of the Pledgees, be advisable for
the purpose.

         The receipt of the Pledgees for the purchase money paid at any such
sale made by it shall be a sufficient discharge therefor to any purchaser of the
Collateral, or any portion thereof, sold as aforesaid; and no such purchaser (or
his or its representatives or assigns), after paying such purchase money and
receiving such receipt, shall be bound to see to the application of such
purchase money or any part thereof or in any manner whatsoever be answerable for
any loss, misapplication, necessity, expediency or regularity of any such sale.

         Except as otherwise provided herein, the Pledgor shall have such rights
of redemption as are afforded by the Uniform Commercial Code as then in effect
in the State of New York.

         5. APPLICATION OF PROCEEDS.

         The proceeds of any sale, or of collection, of all or any part of the
Pledged Stock shall be applied by the Pledgees, without any marshaling of
assets, in the following order:

                  (a) first, to the payment of all of the reasonable costs and
expenses of such sale, including, without limitation, reasonable attorneys'
fees, and all other expenses, liabilities and advances reasonably made or
incurred by the Pledgees in connection therewith; and

                  (b) second, to the payment of the Obligations in such order as
the Pledgees shall determine, until payment in full thereof; and

                  (c) finally, to the payment to the Pledgees, their respective
successors or assigns, or their respective heirs, executors or administrators,
or to whomsoever may be lawfully entitled to receive the same, or as a court of
competent jurisdiction may direct, of any surplus remaining from such proceeds
after payments of the character referred to in subsections (a) and (b) of this
Section 5 shall have been made.

         6. PLEDGEE'S APPOINTED ATTORNEY-IN-FACT.

         Effective upon the occurrence of an Event of Default, the Pledgees,
their successors and assigns, are hereby appointed the attorney-in-fact, with
full power of substitution, of the Pledgor for the purpose of carrying out the
provisions of this Pledge Agreement and taking any action and executing any
instruments which such attorney-in-fact may deem necessary or advisable to
accomplish the purposes hereof, which appointment as attorney- in-fact is
irrevocable and coupled with an interest, including, without limitation, the
power:

                                       5
<PAGE>

                  (a) to demand, sue for, collect, receive and give acquittance
for any and all monies due or to become due upon or by virtue thereof;

                  (b) to receive, take, endorse, assign and deliver any and all
checks, notes, drafts, documents and other negotiable and non-negotiable
instruments and chattel paper taken or received by the Pledgees in connection
therewith;

                  (c) to settle, compromise, prosecute or defend any action or
proceeding with respect thereto; and

                  (d) to discharge any taxes, liens, security interests or other
encumbrances at any time placed thereon.

         7. NO WAIVER.

         No failure on the part of the Pledgees to exercise, and no delay on the
part of the Pledgees in exercising, any right, power or remedy hereunder shall
operate as a waiver thereof; nor shall any single or partial exercise by the
Pledgees of any right, power or remedy hereunder preclude the single or partial
exercise by the Pledgees of any other or further right, power or remedy. The
remedies herein provided are cumulative and are not exclusive of any remedies
provided by law.

         8. TERMINATION OF PLEDGE.

         When all of the Obligations, including, without limitation, the
Debentures, shall have been paid in full, this Pledge Agreement shall terminate.
The Pledgees shall forthwith assign, transfer and deliver to the Pledgor or its
respective successors or assigns without representation, warranty or recourse,
against appropriate receipts, all the Pledged Stock, if any, then held by the
Pledgees in pledge hereunder, free and clear of all liens and encumbrances
created by the Pledgees or its representatives. This provision shall survive the
termination of this Pledge Agreement.

         9. GOVERNING LAW; CONSENT TO JURISDICTION.

State of California, as well as to the jurisdiction of all courts from which an
appeal may be taken from the aforesaid courts, for the purpose of any suit,
action or other proceeding arising out of any of the Pledgors' obligations under
or with respect to this Pledge Agreement, and Pledgor expressly waives any and
all objections Pledgors may now or hereafter have as to the venue in any of such
courts. The Pledgor also waives trial by jury in any such action or proceeding.

         19. GOVERNMENTAL.

         Anything to the contrary contained herein notwithstanding, the Pledgees
will not take any action pursuant to this Pledge Agreement which would
constitute or result in any assignment of a governmentally-issued license or any
transfer of control of any entity owned or controlled by the Debtor if such
assignment of license or transfer of control would require under then existing
law the prior approval of the a government agency (the "Agency"), without first
obtaining such approval of the Agency. The Pledgor agrees to take any action
which the Pledgees may request in order that the Pledgees obtain and enjoy the
full rights and benefits granted to the Pledgees by this Pledge Agreement,

transfer of control required to be signed by the Pledgor, the Debtor, its
officers and/or directors, and necessary or appropriate under the Agency's rules
and regulations for approval of (a) any sale or sales of the Collateral by or on

Collateral.

         20. ADDITIONAL TERMS.

         (a) Pledgor acknowledges that the Law Offices of Michael S. Rosenblum
is acting as agent for the Pledgees. The Agent has acted as legal counsel for
the Pledgees and the Placement Agent in the transaction between the Debtor and
the Pledgees, and may continue to act as legal counsel for such parties, from
time to time, notwithstanding its duties as the Agent hereunder. Pledgor
consents to the Agent acting in such capacity as legal counsel for the Pledgees
and the Placement Agent and waives any claim that such representation represents
a conflict of interest on the part of the Agent. Pledgor understands that the
Pledgees and the Agent are relying explicitly on the foregoing provision in
entering into these transactions with the Debtor and accepting this Pledge
Agreement, as the case may be.

         (b) With respect to the terms of this Pledge Agreement or any matter
arising thereunder, Law Offices of Michael S. Rosenblum shall use the same
degree of care and skill in their exercise as reasonable men use in the conduct
of their own affairs; provided, however, that notwithstanding the foregoing, in
the event that Law Offices of Michael S. Rosenblum shall have received written
notice from the holders in excess of 66-2/3% or more of the Debentures, to act
or refrain from acting under the terms of the Pledge Agreement, Law Offices of
Michael S. Rosenblum shall be bound by such written direction, notwithstanding
the foregoing provisions of this Pledge Agreement.

"Company"), and any Subsidiary thereof and the interests of the Company's
stockholders by providing an opportunity to selected employees, officers and
directors of the Company or any Subsidiary thereof as of the date of the
adoption of the Plan or at any time thereafter to purchase Common Stock of the
Company.  By encouraging such stock ownership, the Company seeks to attract,
retain and motivate such employees and persons and to encourage such employees
and persons to devote their best efforts to the business and financial success
of the Company. It is intended that this purpose will be effected by the
granting of "non-qualified stock options" and/or "incentive stock options" to
acquire the Common Stock of the Company and/or by the granting of Common Stock
or rights to purchase the Common Stock of the Company on a "restricted stock"
basis. Under the Plan, the Committee shall have the authority (in its sole
discretion) to grant "incentive stock options" within the meaning of Section
422(b) of the Code, "non-qualified stock options" as described in Treasury
Regulation Section 1.83--7 or any successor regulation thereto, or "restricted
stock" awards.

     Section 3.  Eligibility.  Awards and/or Options may be granted to any
Employee. The Committee shall have the sole authority to select the persons to
whom Awards and/or Options are to be granted hereunder, and to determine whether
a person is to be granted a Non-Qualified Option, an ISO or an Award or any
combination thereof. No person shall have any right to participate in the Plan.
Any person selected by the Committee for participation during any one period
will not by virtue of such participation have the right to be selected as a
Participant for any other period.  On and after the time that the Company
becomes subject to Code Section 162(m), no Participant shall be granted Options

and/or Award granted under the Plan. If any shares of Common Stock acquired
pursuant to an Award or the exercise of an Option shall be forfeited or
repurchased by the Company, then such shares shall again become available for
issuance pursuant to the Plan.

     4.3.  Special ISO Limitations.

     (a) To the extent that the aggregate fair market value (determined as of
the date an ISO is granted) of the shares of Common Stock with respect to which
ISOs are exercisable for the first time by an Employee during any calendar year
(under all Incentive Stock Option Plans of the Company or any Parent or
Subsidiary of the Company) exceeds $100,000, then the excess thereof shall be
treated as a Non-Qualified Option and not as an ISO.  This rule shall be applied
by taking Options into account in the order in which they are granted.

     (b) No ISO shall be granted to an Employee who, at the time the ISO is
granted, owns (actually or constructively under the provisions of Section 424(d)
of the Code) stock possessing more than 10% of the total combined voting power
of all classes of stock of the Company or any Parent or Subsidiary of the
Company, unless the option price is at least 110% of the fair market value
(determined as of the time the ISO is granted) of the shares of Common Stock
subject to the ISO and the ISO by its terms is not exercisable more than five
years from the date it is granted.

     4.4.  Limitations Not Applicable to Non-Qualified Options or Awards.
Notwithstanding any other provision of the Plan, the provisions of Sections
4.3(a) and (b) shall not apply, nor shall be construed to apply, to any Non-
Qualified Option or Award granted under the Plan.

     Section 5.  Administration of the Plan.

     5.1.  Administration.  The Plan shall be administered by a committee of the
Board of Directors (the "Committee") established by the Board of Directors and
consisting of no less than two persons.  From and after the time that any equity
securities of the Company become registered or required to be registered under
Section 12 of the Securities Exchange Act of 1934 ("Exchange Act"), all members
of the Committee shall be both "non-employee directors" within the meaning of
Rule 16b-3 promulgated under the Exchange Act and "outside directors" within the
meaning of Code Section 162(m).  The Committee shall be appointed from time to
time by, and shall serve at the pleasure of, the Board of Directors.

     5.2.  Grant of Options/Awards.

     (a)  Options.  The Committee shall have the sole authority and discretion
under the Plan (i) to select the Employees who are to be granted Options
hereunder; (ii) to designate whether any Option to be granted hereunder is to be
an ISO or a Non-Qualified Option; (iii) to establish the number of shares of
Common Stock that may be issued under each Option; (iv) to determine the time

which the Company's issued and outstanding shares of Common Stock may be used by
a Participant to exercise an Option); (vi) to impose restrictions and/or
conditions with respect to shares of Common Stock acquired upon exercise of an
Option; (vii) to determine the circumstances under which shares of Common Stock

shares acquired upon exercise of

                                      -3-
<PAGE>

an Option may be sold or otherwise transferred, including, without limitation,
the circumstances and conditions subject to which a proposed sale of shares of
Common Stock acquired upon exercise of an Option may be subject to the Company's
right of first refusal (as well as the terms and conditions of any such right of
first refusal); (ix) to establish a vesting provision for any Option relating to
the time when (or the circumstances under which) the Option may be exercised by
a Participant, including, without limitation, vesting provisions that may be
contingent upon (A) the Company meeting specified financial goals, (B) a change
of control of the Company or (C) the occurrence of other specified events; (x)
to accelerate the time when outstanding Options may be exercised; and (xi) to
establish any other terms, restrictions and/or conditions applicable to any
Option not inconsistent with the provisions of the Plan.

     (b)  Awards.  The Committee shall have the sole authority and discretion
under the Plan (i) to select the Employees who are to be granted Awards
hereunder; (ii) to determine the amount, if any, to be paid by a Participant to
acquire shares of Common Stock pursuant to an Award; (iii) to determine the time
or times and the conditions subject to which Awards may be made; (iv) to
determine the time or times and the conditions subject to which the shares of
Common Stock subject to an Award are to become vested and no longer subject to
forfeiture to and/or repurchase by the Company; (v) to establish transfer
restrictions and the terms and conditions on which any such transfer
restrictions with respect to shares of Common Stock acquired pursuant to an
Award shall lapse; (vi) to establish vesting provisions with respect to any
shares of Common Stock subject to an Award, including, without limitation,
vesting provisions which may be contingent upon (A) the Company meeting
specified financial goals, (B) a change of control of the Company or (C) the
occurrence of other specified events; (vii) to determine the circumstances under
which shares of Common Stock acquired pursuant to an Award may be subject to
repurchase by the Company; (viii) to determine the circumstances and conditions
subject to which any shares of Common Stock acquired pursuant to an Award may be
sold or otherwise transferred, including, without limitation, the circumstances
and conditions subject to which a proposed sale of shares of Common Stock
acquired pursuant to an Award may be subject to the Company's right of first
refusal (as well as the terms and conditions of any such right of first
refusal); (ix) to determine the form of consideration that may be used to
purchase shares of Common Stock pursuant to an Award (including the
circumstances under which the Company's issued and outstanding shares of Common
Stock may be used by a Participant to purchase the Common Stock subject to an
Award); (x) to accelerate time at which any or all restrictions imposed with
respect to any shares of Common Stock subject to an Award will lapse; and (xi)
to establish any other terms, restrictions and/or conditions applicable to any
Award not inconsistent with the provisions of the Plan.

     5.3.  Interpretation.  The Committee shall be authorized to interpret the
Plan and may, from time to time, adopt such rules and regulations, not
inconsistent with the provisions of the Plan, as it may deem advisable to carry
out the purposes of the Plan.

     5.4.  Finality.  The interpretation and construction by the Committee of
any provision of the Plan, any Option and/or Award granted hereunder or any
agreement evidencing any such Option and/or Award shall be final and conclusive

the administration of the Plan or the granting of Options and/or Awards under
the Plan.

<PAGE>

     5.6.  Expenses, Etc.  All expenses and liabilities incurred by the
Committee in the administration of the Plan shall be borne by the Company. The
Committee may employ attorneys, consultants, accountants or other persons in
connection with the administration of the Plan. The Company, and its officers
and directors, shall be entitled to rely upon the advice, opinions or valuations
of any such persons.

     5.7.  Indemnification.  Neither the members of the Board of Directors nor
any member of the Committee shall be liable for any act, omission, or
determination taken or made in good faith with respect to the Plan or any
Options or Awards granted under it, and members of the Board of Directors and
the Committee shall be entitled to indemnification and reimbursement by the
Company in respect of any claim, loss, damage, or expense (including attorneys'
fees, the costs of settling any suit, provided such settlement is approved by
independent legal counsel selected by the Company, and amounts paid in
satisfaction of a judgment, except a judgment based on a finding of bad faith)
arising therefrom to the full extent permitted by law.

     Section 6.  Terms and Conditions of Options.

     6.1.  ISOs.  The terms and conditions of each ISO granted under the Plan
shall be specified by the Committee and shall be set forth in an ISO agreement
between the Company and the Participant in such form as the Committee shall
approve. The terms and conditions of each ISO shall be such that each ISO issued
hereunder shall constitute and shall be treated as an "incentive stock option"
as defined in Section 422(b) of the Code. The terms and conditions of any ISO
granted hereunder need not be identical to those of any other ISO granted
hereunder.

     The terms and conditions of each ISO shall include the following:

     (a)  The option price shall be fixed by the Committee but shall in no event
be less than 100% (or 110% in the case of an Employee referred to in Section
4.3(b) hereof) of the fair market value of the shares of Common Stock subject to
the ISO on the date the ISO is granted. For purposes of the Plan, the fair
market value per share of Common Stock as of any day shall mean the average of
the closing prices of sales of shares of Common Stock on all national securities
exchanges on which the Common Stock may at the time be listed or, if there shall
have been no sales on any such day, the average of the highest bid and lowest
asked prices on all such exchanges at the end of such day, or, if on any day the
Common Stock shall not be so listed, the average of the representative bid and
asked prices quoted in the NASDAQ system as of 3:30 p.m., New York time, on such
day, or, if on any day the Common Stock shall not be quoted in the NASDAQ
system, the average of the high and low bid and asked prices on such day in the
over-the-counter market as reported by National Quotation Bureau Incorporated,
or any similar successor organization. If at any time the Common Stock is not
listed on any national securities exchange or quoted in the NASDAQ system or the
over-the-counter market, the fair market value of the shares of Common Stock
subject to an Option on the date the ISO is granted shall be the fair market
value thereof determined in good faith by the Board of Directors.  The fair
market value of Common Stock subject to an ISO shall be determined without
regard to any restriction other than a restriction which, by its terms, will
never lapse.

                                      -5-
<PAGE>

     (b)  ISOs, by their terms, shall not be transferable otherwise than by will
or the laws of descent and distribution, and, during an Optionee's lifetime, an
ISO shall be exercisable only by the Optionee.

     (c)  All ISOs must be granted within 10 years of the earlier of the date
the Plan is adopted or the date the Plan is approved by the shareholders of the
Company. The Committee shall fix the term of all ISOs granted pursuant to the
Plan (including the date on which such ISO shall expire and terminate),
provided, however, that such term shall in no event exceed ten years from the
date on which such ISO is granted (or, in the case of an ISO granted to an
Employee referred to in Section 4.3(b) hereof, such term shall in no event
exceed five years from the date on which such ISO is granted). Each ISO shall be
exercisable in such amount or amounts, under such conditions and at such times
or intervals or in such installments as shall be determined by the Committee in
its sole discretion.

     (d)  To the extent that the Company or any Parent or Subsidiary of the
Company is required to pay, account for, or withhold any Taxation in respect of:

          (i)  any grant of any ISO, any Non-Qualified Option, and/or any other
     Option referred to in this Plan;

          (ii)  any compensation income realized by any Participant as a result
     of any "disqualifying disposition" of any shares of Common Stock acquired
     upon exercise of an ISO granted hereunder, and

          (iii)  any other exercise, release or other disposal of any Option
     referred to in this Plan

          the Company shall deduct from any payments of any kind otherwise due
     to such Participant (to the extent permitted by law) the aggregate amount
     of such Taxation required to be paid, accounted for or withheld by the
     Company or any person connected with the Company or, if such payments are
     insufficient to satisfy such Taxation such Participant will be required to
     pay to the Company within 30 days of the exercise, release or other
     disposal of any Option, or make other arrangements satisfactory to the
     Company regarding payment to the Company of, the aggregate amount of any
     such taxes.  Draft legislation has been published in the UK which will
     permit employees to pay secondary (employer's) Class 1 NIC's.  Assuming the
     legislation is enacted so that it becomes possible for an employer and an
     employee to agree and/or jointly elect that an employee shall bear any
     employer's Class 1 NIC's as would otherwise become due from the employer on
     the exercise, release or other disposal of an option, the offer of the
     Options contained in this Agreement is conditional upon your agreeing at
     the request of the Company to enter into such written agreement or election
     with the Company and/or with any connected person of the Company as is
     required to procure that you will assume responsibility for such
     (employer's) Class 1 NIC's as would otherwise fall on the Company in
     connection with the grant, exercise, release or other disposal of your
     Options.  Any failure on your part to enter into any such agreement or
     election within seven days of the date of receipt from the Company of a
     notice requiring the same, will result in the cancellation of the Options
     granted to you under the terms of this Agreement and

                                      -6-
<PAGE>

     pending entry by you into such agreement or election you agree that no
     exercise, or further exercise, of the Options will be permitted. All
     matters with respect to the total amount of Taxation to be withheld in
     respect of any such compensation income shall be determined by the Board of
     Directors in its sole discretion.

     (e)  In the sole discretion of the Committee the terms and conditions of
any ISO may (but need not) include any of the following provisions:

          (i)  In the event a Participant shall cease to be employed by the
     Company or any Parent or Subsidiary of the Company on a full-time basis for
     any reason other than as a result of his death or "disability" (within the
     meaning of Section 22(e)(3) of the Code), the unexercised portion of any
     ISO held by such Participant at that time may only be exercised within
     three (3) months after the date on which the Participant ceased to be so
     employed, and only to the extent that the Participant could have otherwise
     exercised such ISO as of the date on which he ceased to be so employed.

          (ii)  In the event a Participant shall cease to be employed by the
     Company or any Parent or Subsidiary of the Company on a full--time basis by
     reason of his "disability" (within the meaning of Section 22(e)(3) of the
     Code), the unexercised portion of any ISO held by such Participant at that
     time may only be exercised within one year after the date on which the
     Participant ceased to be so employed, and only to the extent that the
     Participant could have otherwise exercised such ISO as of the date on which
     he ceased to be so employed.

          (iii)  In the event a Participant shall die while in the full-time
     employ of the Company or a Parent or Subsidiary of the Company (or within a
     period of three (3) months after ceasing to be an Employee for any reason
     other than his "disability" or within a period of one year after ceasing to
     be an Employee by reason of such "disability"), the unexercised portion of
     any ISO held by such Participant at the time of his death may only be
     exercised within one year after the date of such Participant's death, and
     only to the extent that the Participant could have otherwise exercised such
     ISO at the time of his death. In such event, such ISO may be exercised by
     the executor or administrator of the Participant's estate or by any person
     or persons who shall have acquired the ISO directly from the Participant by
     bequest or inheritance.

     (f)  No Option granted hereunder shall qualify as an ISO unless the Plan is
approved by the shareholders of the Company within 12 months before or after the
date the Plan is adopted by the Board of Directors.

     6.2.  Non-Qualified Options.  The terms and conditions of each Non-
Qualified Option granted under the Plan shall be specified by the Committee, in
its sole discretion, and shall be set forth in a written option agreement
between the Company and the Participant in such form as the Committee shall
approve. The terms and conditions of each Non-Qualified Option will be such (and
each Non-Qualified Option Agreement shall expressly so state) that each Non-
Qualified Option issued hereunder shall not constitute nor be treated as an
"incentive stock option" as defined in Section 422(b) of the Code but will be a
"non-qualified stock option" for Federal, state and local income tax purposes.
The terms and conditions of

                                      -7-
<PAGE>

any Non-Qualified Option granted hereunder need not be identical to those of any
other Non-Qualified Option granted hereunder.

     The terms and conditions of each Non-Qualified Option Agreement shall
include the following:

     (a)  The option (exercise) price shall be fixed by the Committee and may be
equal to, more than or less than 100% of the fair market value of the shares of
Common Stock subject to the Non-Qualified Option on the date such Non-Qualified
Option is granted, provided, however, that the option (exercise) price shall not
be less than the par value of such shares of Common Stock.

     (b)  The Committee shall fix the term of all Non-Qualified Options granted
pursuant to the Plan (including the date on which such Non--Qualified Option
shall expire and terminate).  Each Non-Qualified Option shall be exercisable in
such amount or amounts, under such conditions (including provisions governing
the rights to exercise such Non--Qualified Option), and at such times or
intervals or in such installments as shall be determined by the Committee in its
sole discretion.

     (c)  Except as otherwise provided in an individual Option Agreement, Non-
Qualified Options shall not be transferable otherwise than by will or the laws
of descent and distribution, or a domestic relations order, and during a
Participant's lifetime a Non-Qualified Option shall be exercisable only by the
Participant or an alternate payee under a domestic relations order.

     (d)  To the extent that the Company or a connected person is required to
withhold, pay or account for any Taxation in respect of:

          (i)  any grant of any ISO, any Non-Qualified Option, and/or any other
     Option referred to in this Plan;

          (ii)  any compensation income or other gain or income realized by any
     Participant in respect of a Non-Qualified Option granted hereunder or in
     respect of any shares of Common Stock acquired upon exercise of a Non-
     Qualified Option; or

          (iii)  any other exercise, release or other disposal of any Option
     referred to in this Plan

          the Company shall deduct from any payments of any kind otherwise due
     to such Participant (to the extent permitted by law) the aggregate amount
     of such Taxation required to be so withheld or, if such payments are
     insufficient to satisfy such Taxation or if no such payments are due or to
     become due to such Participant, then, such Participant will be required to
     pay to the Company within 30 days of the exercise, release or other
     disposal of the Option, or make other arrangements satisfactory to the
     Company (including, with prior Committee approval, use of a promissory note
     in favor of the Company) regarding payment to the Company of, the aggregate
     amount of any such taxes. Draft legislation has been published in the UK
     which will permit employees to pay secondary (employer's) Class 1 NIC's.
     Assuming the legislation is enacted so that it becomes possible for an
     employer and an employee

                                      -8-
<PAGE>

     to agree and/or jointly elect that an employee shall bear any employer's
     Class 1 NIC's as would otherwise become due from the employer on the
     exercise, release or other disposal of an option, the offer of the Options
     contained in this Agreement is conditional upon your agreeing at the
     request of the Company to enter into such written agreement or election
     with the Company and/or with any connected person of the Company as is
     required to procure that you will assume responsibility for such
     (employer's) Class 1 NIC's as would otherwise fall on the Company in
     connection with the grant, exercise, release or other disposal of your
     Options. Any failure on your part to enter into any such agreement or
     election within seven days of the date of receipt from the Company of a
     notice requiring the same, will result in the cancellation of the Options
     granted to you under the terms of this Agreement and pending entry by you
     into such agreement or election you agree that no exercise, or further
     exercise, of the Options will be permitted. All matters with respect to the
     total amount of Taxation to be withheld or the arrangements to be entered
     into in respect of any such compensation income, gain or other income on
     the exercise, release or other disposal of an Option shall be determined by
     the Board of Directors in its sole discretion.

     Section 7.  Terms and Conditions of Awards.  The terms and conditions of
each Award granted under the Plan shall be specified by the Committee, in its
sole discretion, and shall be set forth in a written agreement between the
Participant and the Company, in such form as the Committee shall approve. The
terms and provisions of any Award granted hereunder need not be identical to
those of any other Award granted hereunder.

     The terms and conditions of each Award shall include the following:

     (a)  The amount, if any, to be paid by a Participant to acquire the shares
of Common Stock pursuant to an Award shall be fixed by the Board of Directors
(or the Committee).

     (b)  Each Award shall contain such vesting provisions, such transfer
restrictions and such other restrictions and conditions as the Committee, in its
sole discretion, may determine, including, without limitation, the circumstances
under which the Company shall have the right and option to repurchase shares of
Common Stock acquired pursuant to an Award.

     (c)  Stock certificates representing Common Stock acquired pursuant to an
Award shall bear a legend referring to the restrictions imposed on such Stock
and such other matters as the Committee may determine.

     (d)  To the extent that the Company is required to withhold any Federal,
state or local taxes in respect of any compensation income realized by the
Participant in respect of an Award granted hereunder, or in respect of any
shares acquired pursuant to an Award, or in respect of the vesting of any such
shares of Common Stock, then the Company shall deduct from any payments of any
kind otherwise due to such Participant the aggregate amount of such Federal,
state or local taxes required to be so withheld or, if such payments are
insufficient to satisfy such Federal, state or local taxes, or if no such
payments are due or to become due to such Participant, then, such Participant
will be required to pay to the

                                      -9-
<PAGE>

Company, or make other arrangements satisfactory to the Company regarding
payment to the Company of, the aggregate amount of any such taxes. All matters
with respect to the total amount of taxes to be withheld in respect of any such
compensation income shall be determined by the Committee in its sole discretion.

     Section 8.  Adjustments.  In the event that, after the adoption of the Plan
by the Board of Directors, the outstanding shares of the Company's Common Stock
shall be increased or decreased or changed into or exchanged for a different
number or kind of shares of stock or other securities of the Company or of
another corporation through reorganization, merger or consolidation,
recapitalization, reclassification, stock split, split-up, combination or
exchange of shares or declaration of any dividends payable in Common Stock, the
Board of Directors shall appropriately adjust (i) the number of shares of Common
Stock (and the option price per share) subject to the unexercised portion of any
outstanding Option (to the nearest possible full share), provided, however, that
the limitations of Section 424 of the Code shall apply with respect to
adjustments made to ISOs; (ii) the number of shares of Common Stock to be
acquired pursuant to an Award which have not become vested, and (iii) the number
of shares of Common Stock for which Options and/or Awards may be granted under
the Plan, as set forth in Section 4.1 hereof, and such adjustments shall be
effective and binding for all purposes of the Plan.

     Section 9.  Effect of the Plan on Employment Relationship.  Neither the
Plan nor any Option and/or Award granted hereunder to a Participant shall be
construed as conferring upon such Participant any right to continue in the
employ of (or otherwise provide services to) the Company or any Subsidiary or
Parent thereof, or limit in any respect the right of the Company or any
Subsidiary or Parent thereof to terminate such Participant's employment or other
relationship with the Company or any Subsidiary or Parent, as the case may be,
at any time.

     Section 10.  Amendment of the Plan.  The Committee or Board of Directors
may amend or suspend the Plan or any portion thereof at any time, provided such
amendment is made with stockholder approval if such approval is necessary to
comply with any tax or regulatory requirement, including for these purposes any
approval which is a requirement for ISO treatment or, if applicable once any
equity securities of the Company become registered under Section 12 of the
Exchange Act, for exemptive relief under Section 16(b) of the Exchange Act or
which is a requirement for the performance-based compensation exception under
Code Section 162(m). The Committee in its sole discretion may amend the Plan so
as to conform with local rules and regulations subject to any provisions to the
contrary specified herein.

     Section 11.  Amendment of an Option or Award Agreement.  In its sole and
complete discretion, the Committee may at any time amend any Option or Award
Agreement for the following reasons: (i) additions and/or changes to the Code,
any federal or state securities law, or other law or regulations applicable to
the Option or Award, are made, and such additions and/or changes have some
effect on the Option or Award; or (ii) any other event not described in clause

provided however, except for capital adjustments described in Section 8, the
Committee may not reduce the exercise price of an Option or Award.

     Section 12.  Exemption from Computation of Compensation for Other Purposes.
By acceptance of an applicable Option or Award, subject to the conditions of
such Option or Award, each Participant shall be considered in agreement that all
shares sold or awarded and all Options granted under this Plan shall be
considered special incentive compensation and will be exempt from inclusion as
"wages" or "salary" in pension, retirement, life insurance, and other employee
benefits arrangements of the Company, except as determined otherwise by the
Company. In addition, each beneficiary of a deceased Participant shall be in
agreement that all such Options and Awards will be exempt from inclusion in
"wages" or "salary" for purposes of calculating benefits of any life insurance
coverage sponsored by the Company.

     Section 13.  Listing, Registration and Other Legal Compliance.  No Options,
Awards or shares of the Common Stock shall be required to be issued or granted
under the Plan unless legal counsel to the Company shall be satisfied that such
issuance or grant will be in compliance with all applicable federal and state
securities laws and regulations and any other applicable laws or regulations.
The Committee may require, as a condition of any payment or share issuance, that
certain agreements, undertakings, representations, certificates, and/or
information, as the Committee may deem necessary or advisable, be executed or
provided to the Company to assure compliance with all such applicable laws or
regulations. Any certificates for shares of Common Stock delivered under the
Plan may be subject to such stock-transfer orders and such other restrictions as
the Committee may deem advisable under the rules, regulations, or other
requirements of the Securities and Exchange Commission, any stock exchange upon
which the Common Stock is then listed, and any applicable federal or state
securities law. In addition, if, at any time specified herein (or in any
Agreement or otherwise) for (a) the making of any Option or Award, or the making
of any determination, (b) the issuance or other distribution of Common Stock, or
(c) the payment of amounts to or through a Participant with respect to any
Option or Award, any law, rule, regulation, or other requirement of any
governmental authority or agency shall require the Company, any affiliate, or
any Participant (or any estate, designated beneficiary, or other legal
representative thereof) to take any action in connection with any such
determination, any such shares to be issued or distributed, any such payment, or
the making of any such determination, as the case may be, shall be deferred
until such required action is taken.

     Section 14.  Rights as Stockholder.  Subject to the Award provisions, no
Participant or beneficiary shall be deemed a stockholder of the Company nor have
any rights as such with respect to any shares to be provided under the Plan
until he or she has become the holder of such shares. Notwithstanding the
aforementioned, with respect to restricted stock Awards under this Plan, the
Participant or beneficiary of such Award shall be deemed the owner of such
shares provided herein. As such, unless contrary to the provisions herein or in
any such related Agreement, such stockholder shall be entitled to full voting,
dividend and distribution rights as provided any other Company stockholder for
as long as the Participant continues to be deemed the owner of such stock.

     Section 15.  Construction of the Plan.  The Plan, and its rules, rights,
agreements and regulations, shall be governed, construed, interpreted and
administered solely in accordance with the laws of the state of Delaware . In
the event any provision of the Plan shall be held invalid, illegal or
unenforceable, in whole or in part, for any reason, such determination shall not
affect the validity, legality or enforceability of any remaining provision,
portion of

                                      -11-

provision or the Plan overall, which shall remain in full force and effect as if
the Plan had been absent the invalid, illegal or unenforceable provision or
portion thereof

     Section 16.  Termination of the Plan.  The Board of Directors may terminate
the Plan at any time. Unless the Plan shall theretofore have been terminated by
the Board of Directors, the Plan shall terminate ten years after the date of its
initial adoption by the Board of Directors. No Option and/or Award may be
granted hereunder after termination of the Plan. The termination or amendment of
the Plan shall not alter or impair any rights or obligations under any Option
and/or Award theretofore granted under the Plan.

1st  February, 1998, the date on which the Plan was adopted by the Board of
Directors of the Company.

                       AIRSPAN COMMUNICATIONS CORPORATION

                      NON-QUALIFIED STOCK OPTION AGREEMENT

Employee/Optionee:     [Name]

Number of shares of    [Shares]
Common Stock subject
to this Agreement:

Pursuant to the 1998 Airspan Communications Corporation Stock Option and
Restricted Stock Plan (the "Plan"), a Committee (the "Committee") of the Board
of Directors of Airspan Communications Corporation (the "Company") has granted
to you on this date an option (the "Option") to purchase the number of shares of
the Company's Common Stock, $.0003 par value ("Common Stock"), set forth above.
Such shares (as the same may be adjusted as described in Section 10 below) are
herein referred to as the "Option Shares".  The Option shall constitute and be
treated at all times by you and the Company as a "non-qualified stock option"
for Federal income tax purposes and shall not constitute and shall not be
treated as an "incentive stock option" as defined under Section 422(b) of the
Internal Revenue Code of 1986, as amended (the "Code").  The terms and
conditions of the Option are set out below.

     1.   Date of Grant.  The Option is granted to you as of [Board meeting].

     2.   Termination of Option. Except as provided below, your right to
          exercise the Option (and to purchase the Option Shares) shall expire
          and terminate in all events on the earliest of (i) ten (10) years from
          the date of grant, or (ii) the date provided in Section 8 below in the
          event you cease to be employed by the Company or any subsidiary or
          affiliate thereof. Provided, however, that notwithstanding clauses (i)
          and (ii) and anything else to the contrary in this Agreement, if you
          are employed by the Company or any subsidiary or affiliate of the
          Company immediately before a Change in Control (as defined below), and
          if the Company or any successor, assign, or purchaser thereof does not
          either (A) continue your Option (as adjusted, if necessary, to retain
          its pre Change in Control economic value and aggregate "spread"
          between the Option Shares' fair market value and exercise price) or
          (B) grant you a new Option of at least equivalent economic value,
          aggregate "spread," and other terms and conditions as your pre Change
          in Control Option, then you will automatically vest in an additional
          50% of any remaining unvested Options that you may hold, and,
          notwithstanding anything herein to the contrary, you may exercise all
          such vested Options (together with any other previously or
          subsequently vested Options) until the later of (i) the date specified
          in Section 8 below or (ii) one (1) year from such Change in Control,
          but in no event longer than ten (10) years from the original date of
          grant.

3.  Option Price.  The purchase price to be paid upon the exercise of the Option
is $[price] (price in words) per share (subject to adjustment as provided in
Section 10 hereof), which is equal to the Fair Market Value of a share of Common
Stock on the date of grant.

4.  Vesting.  (a) Unless otherwise accelerated upon a Change in Control as
provided for in Section 2 above, upon the one (1) year anniversary of [hire
date] the Option shall become exercisable to purchase ("vest with respect to")
25% of the total number of Option Shares, and, after the first such anniversary
date, shall vest each month for the next 36 months with respect to an additional
1/48 of the total number of Option Shares (rounded to the nearest whole share),
such that 100% of the Option Shares will vest in four (4) years.

(b)  For purposes hereof, a "Change in Control" shall be deemed to have occurred
if the conditions set forth in any one of the following paragraphs shall have
been satisfied:
<PAGE>

     (1)  Any Person becomes the beneficial owner of shares having 50% or more
     of the total number of votes that may be case for the election of directors
     of the Company; or

     (2)  As a result of, or in connection with, any tender or exchange offer,
     merger or other business combination, sale of assets or contested election,
     or any combination of the foregoing a"Transaction"), the persons who were
     directors of the Company before the Transaction shall cease to constitute a
     majority of the Board of Directors of the Company or any successor to the
     Company or its assets; or

     (3)  If at any time (i) the Company shall consolidate with, or merge with,
     any other person and the Company shall not be the continuing or surviving
     corporation, (ii) any Person shall consolidate with, or merge with, the
     Company and the Company shall be the continuing or surviving corporation
     and in connection therewith, all or part of the outstanding stock shall be
     changed into or exchanged for stock or other securities of any other Person
     or cash or any other property, (iii) the Company shall be a party to a
     statutory share exchange with any other Person after which the Company is a
     Subsidiary of any other Person, or (iv) the Company shall sell or otherwise
     transfer 50% or more of the assets or earnings power of the Company and its
     subsidiaries (taken as a whole) to any Person or Persons.  The term
     "Person" shall have the meaning ascribed to such term in Section 3(a)(9) of
     the Securities Exchange Act of 1934 ("Exchange Act") and used in Sections
     13(d) and 14(d) thereof, including a "group" as defined in Section 13(d)
     thereof.

(c)  If a Change in Control occurs and the Company fails to remain in existence,
the Option shall become an obligation of the person succeeding to the business
of the Company or otherwise responsible for the Company's obligations.

(d)  Nothing in this Agreement pertaining to a Change in Control shall limit or
restrict the rights otherwise provided to you in this Agreement or the
exercisability of the Option.

5.  Additional Provisions Relating to Exercise.  Once you become entitled to
exercise the Option (and purchase Option Shares) as provided in Section 4
hereof, such right will continue until the date on which the Option expires and
terminates pursuant to Section 2 hereof.

6.  Exercise of Option.  To exercise the Option, you must deliver a completed
copy of the attached Option Exercise Form to the address indicated on the Form,
specifying the number of Option Shares being purchased as a result of such
exercise, together with payment of the full option price for the Option Shares
being purchased and the applicable income, social security (including, without
limitation, both primary (employee's) and secondary (employer's) Class 1
National Insurance Contributions ("NIC's"), and any other tax obligation arising
on the grant, exercise, release or other disposal of the Options or Option
Shares to the extent permitted by law (the "Tax Indemnity").  Unless otherwise
agreed to by the Committee, payment of the option price and payment in respect
of the Tax Indemnity must be made in cash or by cashier's check; provided,
however, that with the prior approval of the Committee, payment of such option
price and/or Tax Indemnity may instead be made, in whole or in part, by the
delivery to the Company of a promissory note in a form and amount satisfactory
to the Committee, provided that the principal amount of such note shall not
exceed the excess of such aggregate option price and Tax Indemnity obligation
over the aggregate par value of the purchased Option Shares.  Notwithstanding
anything to the contrary in this Agreement, no shares of stock purchased upon
exercise of the Option, and no certificate representing such shares, shall be
issued or delivered if (a) such shares have not been admitted to listing upon
official notice of issuance on each stock exchange, if any, upon which shares of
that class are then listed, or (b) in the opinion of counsel to the Company,
such issuance or delivery would (i) cause the Company to be in violation of or
to incur liability under any federal, state or other securities law, or any
other requirement of law or any requirement of any stock exchange regulations or
listing agreement to which the Company is a party, or of any administrative or
regulatory body having jurisdiction over the
<PAGE>

Company or (ii) require registration (apart from any registrations as have been
theretofore completed by the Company covering such shares) under any federal,
state, or other securities or similar law.

7.  Transferability of Option.  The Option may not be transferred by you (other
than by will or the laws of descent and distribution or a domestic relations
order) and may be exercised during your lifetime only by you or by an alternate
payee under a domestic relations order.

8.  Termination of Employment.  (a)  In the event that (i) the Company or any
subsidiary, affiliate, or parent thereof terminates your employment, or (ii) you
terminate your employment for any reason whatsoever (other than as a result of
your death or total and permanent disability (as determined by the Company or
its designated representative), then the Option may only be exercised within
ninety (90) days after the date you cease to be so employed, and only to the
same extent that you were entitled to exercise the Option on the date you ceased
to be so employed by reason of such termination and had not previously done so.

          (b)  In the event that you cease to be employed on a full-time basis
by the Company or any subsidiary, affiliate, or parent thereof by reason of
total and permanent disability (as determined by the Company or its designated
representative), then the Option may only be exercised within one year after the
date you cease to be so employed, and only to the same extent that you were
entitled to exercise the Option on the date you ceased to be so employed by
reason of such disability and had not previously done so.

          (c)  In the event that you die while employed by the Company or any
subsidiary, affiliate, or parent thereof (or die within a period of one year
after ceasing to be employed by the Company or any subsidiary, affiliate, or
parent thereof by reason of disability (as described in Section 8(b) hereof) or
within 90 days of ceasing to be so employed for any other reason), the Option
may only be exercised within one year after your death. In such event, the
Option may be exercised during such one-year period by the executor or
administrator of your estate or by any person who shall have acquired the Option
through bequest or inheritance, but only to the same extent that you were
entitled to exercise the Option immediately prior to the time of your death and
you had not previously done so.

          (d)  Notwithstanding any provision contained in this Section 8 to the
contrary, (i) the time limits provided for in this Section 8 shall be subject to
extention in the event of a Change in Control, to the extent provided for in
Section 2 hereof, and (ii) in no event may the Option be exercised to any extent
by anyone after the tenth (10th) anniversary of the date of grant of the Option.

9.  Representations.  (a)  You understand that the restrictions on the transfer
of any Option Shares under Section 15 hereof shall apply.  You represent and
warrant to the Company that, upon exercise of the Option, you will be acquiring
the Option Shares for your own account for the purpose of investment and not
with a view to or for sale in connection with any distribution thereof, and you
understand that (i) neither the Option nor the Option Shares have been
registered with the Securities and Exchange Commission, (ii) the Option Shares
are not transferable or disposable until the class of equity securities
represented by the Option Shares are registered under Section 12 of the Exchange
Act, (iii) the Option Shares must be held indefinitely by you unless a
subsequent disposition thereof is registered under the Securities Act of 1933,
as amended, and the securities laws of any applicable state or other
jurisdiction, or is exempt from such registration, and (iv) the restrictions on
the transfer of such shares under Section 15 hereof shall apply until the lapse
conditions thereof are satisfied.  The stock certificates for any Option Shares
issued to you will bear the following legend:

          THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED
          UNDER THE SECURITIES ACT OF
<PAGE>

          1933 OR THE SECURITIES LAWS OF ANY STATE OR OTHER JURISDICTION. THESE
          SHARES MAY NOT BE SOLD, TRANSFERRED OR OTHERWISE DISPOSED OF UNLESS
          THEY HAVE BEEN REGISTERED UNDER THAT ACT AND THE SECURITIES LAWS OF
          ANY APPLICABLE STATE AND OTHER JURISDICTION, OR AN EXEMPTION FROM
          REGISTRATION IS AVAILABLE. THE TRANSFER OF SHARES OF COMMON STOCK
          REPRESENTED BY THIS CERTIFICATE IS ALSO RESTRICTED PURSUANT TO A STOCK
          OPTION AGREEMENT, DATED AS OF [BOARD MEETING DATE], A COPY OF WHICH IS
          ON FILE AT THE PRINCIPAL OFFICE OF THE COMPANY.

          IN ACCORDANCE WITH THE PROVISIONS OF SECTION 151(f) OF THE WASHINGTON
          GENERAL CORPORATION LAW, THE COMPANY WILL FURNISH WITHOUT CHARGE TO
          EACH STOCKHOLDER WHO SO REQUESTS THE POWERS, DESIGNATIONS, PREFERENCES
          AND RELATIVE, PARTICIPATING, OPTIONAL, OR OTHER SPECIAL RIGHTS OF EACH
          CLASS OF STOCK OR SERIES THEREOF OF THE COMPANY AND THE
          QUALIFICATIONS, LIMITATIONS, OR RESTRICTIONS OF SUCH PREFERENCES
          AND/OR RIGHTS.

          (b)  You further represent and warrant that you understand the
Taxation consequences of the granting of the Option to you, the acquisition of
rights to exercise the Option with respect to any Option Shares, the exercise,
release or other disposal of the Option and purchase of Option Shares, and the
subsequent sale or other disposition of any Option Shares. In addition, you
understand that the Company will be required to pay, account for or withhold
Taxation in respect of any compensation income, or other income or gain realized
by you upon exercise of the Option granted hereunder. To the extent that the
Company is required to pay, account for or withhold any such Taxes, then, unless
both you and the Committee have otherwise agreed upon alternate arrangements,
you hereby agree that the Company may deduct from any payments of any kind
otherwise due to you an amount equal to the total Taxation required to be so
paid, accounted for or withheld (as permitted by law), or if such payments are
inadequate to satisfy such Taxation, or if no such payments are due or to become
due to you, then you agree to provide the Company with cash funds or make other
arrangements satisfactory to the Company regarding such payment. Furthermore,
you represent and warrant that should the draft legislation regarding secondary
(employer's) Class 1 NIC's be enacted so that it becomes possible for an
employer and an employee to agree and/or jointly elect that an employee shall
bear any employer's Class 1 NIC's as would otherwise become due from the
employer on the exercise, release or other disposal of an option, the offer of
the Options contained in this Agreement is conditional upon your agreeing at the
request of the Company to enter into such written agreement or election with the
Company and/or with any connected person of the Company as is required to
procure that you will assume responsibility for such (employer's) Class 1 NIC's
as would otherwise fall on the Company in connection with the grant, exercise,
release or other disposal of your Options. Any failure on your part to enter
into any such agreement or election within seven days of the date of receipt
from the Company of a notice requiring the same, will result in the forfeiture
of the Options granted to you under the terms of this Agreement and pending
entry by you into such agreement or election you agree that no exercise, or
further exercise, of the Options will be permitted. It is understood that all
matters with respect to the total amount of taxes to be withheld in respect of
any such compensation income shall be determined by the Company in its sole
discretion.

10.  Adjustments.  In the event that, after the date hereof, the outstanding
shares of the Company's Common Stock shall be increased or decreased or changed
into or exchanged for a different number or kind of shares of stock or other
securities of the Company or of another corporation through reorganization,
merger or consolidation, recapitalization, reclassification,
<PAGE>

stock split, split-up, combination or exchange of shares or declaration of any
dividends payable in Common Stock, the Board of Directors shall appropriately
adjust the number of shares of Common Stock (and the option price per share)
subject to the unexercised portion of the Option (to the nearest possible full
share), and such adjustment shall be effective and binding for all purposes of
this Agreement and the Plan.

11.  Continuation of Employment.  Neither the Plan nor the Option shall confer
upon you any right to continue in the employ of (or any other relationship with)
the Company or any subsidiary, affiliate, or parent thereof, or limit in any
respect the right of the Company or any subsidiary, affiliate, or parent thereof
to terminate your employment or other relationship with the Company or any
subsidiary, affiliate, or parent thereof, as the case may be, at any time.  This
Agreement shall supersede any other agreement between the Company (or one of its
affiliates or subsidiaries) and you with respect to any obligation of the
Company (or such affiliate or subsidiary) to grant any Option or distribute or
sell any Common Stock to you.  Any such obligation shall be null, void and of no
effect.

12.  Stockholder Rights.  No person or entity shall be entitled to vote, receive
dividends, or be deemed for any purpose the holder of any Option Shares until
the Option shall have been duly exercised to purchase such Option Shares in
accordance with the provisions of this Agreement.

13.  Plan Documents.  This Agreement is qualified in its entirety by reference
to the provisions of the Plan, as amended from time to time, which are hereby
incorporated herein by reference.  Capitalized terms not defined herein shall
have the meaning ascribed to them in the Plan.  However, notwithstanding the
above, no Plan amendment may deprive you of any Options theretofore granted
under the Plan without your consent, and no Plan amendment requiring shareholder
approval (if any) may be made without such shareholder approval.

The interpretation and construction by the Committee of the Plan, this
Agreement, the Options granted hereunder, and such rules and regulations as may
be adopted by the Committee for the purpose of administering the Plan, shall be
final and binding upon you.  Until the Options shall expire, terminate, or be
exercised in full, the Company shall, upon written request therefor, send a copy
of the Plan, in its then-current form, to you or any other person or entity then
entitled to exercise the Options.

14.  Governing Law.  This Agreement shall be governed by and construed in
accordance with the laws of the State of Delaware, but without regard to the
principle of conflict of laws thereof.  If any one or more provisions of this
Agreement shall be found to be illegal or unenforceable in any respect, the
validity and enforceability of the remaining provisions hereof shall not in any
way be affected or impaired thereby.

15.  Restrictions on Transfer.

(including by operation of law) assign, bequeath, devise, encumber, hypothecate,
mortgage, pledge, sell, or otherwise transfer or dispose of (collectively
