                                 TELECORE, INC.
                      1999 STOCK OPTION/STOCK ISSUANCE PLAN

                                  ARTICLE ONE

                               GENERAL PROVISIONS

         I.       PURPOSE OF THE PLAN

                  This 1999 Stock Option/Stock Issuance Plan is intended to
promote the interests of TeleCore, Inc., a Delaware corporation, by providing
eligible persons in the Corporation's employ or service with the opportunity to
acquire a proprietary interest, or otherwise increase their proprietary
interest, in the Corporation as an incentive for them to continue in such employ
or service.

                  Capitalized terms herein shall have the meanings assigned to
such terms in the attached Appendix.

         II.      STRUCTURE OF THE PLAN

                  A. The Plan shall be divided into two (2) separate equity
programs:

                           (i) the Option Grant Program under which eligible
         persons may, at the discretion of the Plan Administrator, be granted
         options to purchase shares of Common Stock, and

                           (ii) the Stock Issuance Program under which eligible
         persons may, at the discretion of the Plan Administrator, be issued
         shares of Common Stock directly, either through the immediate purchase
         of such shares or as a bonus for services rendered the Corporation (or
         any Parent or Subsidiary).

                  B. The provisions of Articles One and Four shall apply to both
equity programs under the Plan and shall accordingly govern the interests of all
persons under the Plan.

         III.     ADMINISTRATION OF THE PLAN

                  A. The Plan shall be administered by the Board. However, any
or all administrative functions otherwise exercisable by the Board may be
delegated to the Committee. Members of the Committee shall serve for such period
of time as the Board may determine and shall be subject to removal by the Board
at any time. The Board may also at any time terminate the functions of the
Committee and reassume all powers and authority previously delegated to the
Committee.

                  B. The Plan Administrator shall have full power and authority
(subject to the provisions of the Plan) to establish such rules and regulations
as it may deem appropriate for proper administration of the Plan and to make
such determinations under, and issue such

<PAGE>   2

interpretations of, the Plan and any outstanding options or stock issuances
thereunder as it may deem necessary or advisable. Decisions of the Plan
Administrator shall be final and binding on all parties who have an interest in
the Plan or any option grant or stock issuance thereunder.

         IV.      ELIGIBILITY

                  A. The persons eligible to participate in the Plan are as
follows:

                           (i) Employees,

                           (ii) non-employee members of the Board or the
         non-employee members of the board of directors of any Parent or
         Subsidiary, and

                           (iii) consultants and other independent advisors who
         provide services to the Corporation (or any Parent or Subsidiary).

                  B. The Plan Administrator shall have full authority to
determine, (i) with respect to the grants made under the Option Grant Program,
which eligible persons are to receive such grants, the time or times when those
grants are to be made, the number of shares to be covered by each such grant,
the status of the granted option as either an Incentive Option or a
Non-Statutory Option, the time or times when each option is to become
exercisable, the vesting schedule (if any) applicable to the option shares and
the maximum term for which the option is to remain outstanding, and (ii) with
respect to stock issuances made under the Stock Issuance Program, which eligible
persons are to receive such issuances, the time or times when those issuances
are to be made, the number of shares to be issued to each Participant, the
vesting schedule (if any) applicable to the issued shares and the consideration
to be paid by the Participant for such shares.

                  C. The Plan Administrator shall have the absolute discretion
either to grant options in accordance with the Option Grant Program or to effect
stock issuances in accordance with the Stock Issuance Program.

         V.       STOCK SUBJECT TO THE PLAN

                  A. The stock issuable under the Plan shall be shares of
authorized but unissued or reacquired Common Stock. The maximum number of shares
of Common Stock which may be issued over the term of the Plan shall not exceed
1,474,360 shares.(1)

                  B. Shares of Common Stock subject to outstanding options shall
be available for subsequent issuance under the Plan to the extent (i) the
options expire or terminate for any reason prior to exercise in full or (ii) the
options are cancelled in accordance with the cancellation-regrant provisions of
Article Two. Unvested shares issued under the Plan and subsequently repurchased
by the Corporation, at the option exercise or direct issue price paid

-----------------
(1)      By resolution of the Board of Directors of Viasource Communications,
         Inc. ("Viasource"), 1,294,118 shares of Viasource Common Stock are
         reserved for issuance pursuant to options granted under the plan.

                                       2

per share, pursuant to the Corporation's repurchase rights under the Plan shall
be added back to the number of shares of Common Stock reserved for issuance
under the Plan and shall accordingly be available for reissuance through one or
more subsequent option grants or direct stock issuances under the Plan.

                  C. Should any change be made to the Common Stock by reason of
any stock split, stock dividend, recapitalization, combination of shares,
exchange of shares or other change affecting the outstanding Common Stock as a
class without the Corporation's receipt of consideration, appropriate
adjustments shall be made to (i) the maximum number and/or class of securities
issuable under the Plan and (ii) the number and/or class of securities and the
exercise price per share in effect under each outstanding option in order to
prevent the dilution or enlargement of benefits thereunder. The adjustments
determined by the Plan Administrator shall be final, binding and conclusive. In
no event shall any such adjustments be made in connection with the conversion of
one or more outstanding shares of the Corporation's preferred stock into shares
of Common Stock.

                                   ARTICLE TWO

                              OPTION GRANT PROGRAM

         I.       OPTION TERMS

                  Each option shall be evidenced by one or more documents in the
form approved by the Plan Administrator; PROVIDED, however, that each such
document shall comply with the terms specified below. Each document evidencing
an Incentive Option shall, in addition, be subject to the provisions of the Plan
applicable to such options.

               A. EXERCISE PRICE.

                  1. The exercise price per share shall be fixed by the Plan
Administrator in accordance with the following provisions:

                           (i) The exercise price per share shall not be less
         than eighty-five percent (85%) of the Fair Market Value per share of
         Common Stock on the option grant date.

                           (ii) If the person to whom the option is granted is a
         10% Stockholder, then the exercise price per share shall not be less
         than one hundred ten percent (110%) of the Fair Market Value per share
         of Common Stock on the option grant date.

                  2. The exercise price shall become immediately due upon
exercise of the option and shall, subject to the provisions of Section I of
Article Four and the documents evidencing the option, be payable in cash or
check made payable to the Corporation. Should the Common Stock be registered
under Section 12 of the 1934 Act at the time the option is exercised, then the
exercise price may also be paid as follows:

                           (i) in shares of Common Stock held for the requisite
         period necessary to avoid a charge to the Corporation's earnings for
         financial reporting purposes and valued at Fair Market Value on the
         Exercise Date, or

                           (ii) to the extent the option is exercised for vested
         shares, through a special sale and remittance procedure pursuant to
         which the Optionee shall concurrently provide irrevocable instructions
         (A) to a Corporation-designated brokerage firm to effect the immediate
         sale of the purchased shares and remit to the Corporation, out of the
         sale proceeds available on the settlement date, sufficient funds to
         cover the aggregate exercise price payable for the purchased shares
         plus all applicable Federal, state and local income and employment
         taxes required to be withheld by the Corporation by reason of such
         exercise and (B) to the Corporation to deliver the certificates for the
         purchased shares directly to such brokerage firm in order to complete
         the sale.

                                       4
<PAGE>   5

                  Except to the extent such sale and remittance procedure is
utilized, payment of the exercise price for the purchased shares must be made on
the Exercise Date.

                  B. EXERCISE AND TERM OF OPTIONS. Each option shall be
exercisable at such time or times, during such period and for such number of
shares as shall be determined by the Plan Administrator and set forth in the
documents evidencing the option grant. However, no option shall have a term in
excess of ten (10) years measured from the option grant date.

                  C. EFFECT OF TERMINATION OF SERVICE.

                  1. The following provisions shall govern the exercise of any
options held by the Optionee at the time of cessation of Service or death:

                           (i) Should the Optionee cease to remain in Service
         for any reason other than death, Disability or Misconduct, then the
         Optionee shall have a period of three (3) months following the date of
         such cessation of Service during which to exercise each outstanding
         option held by such Optionee.

                           (ii) Should Optionee's Service terminate by reason of
         Disability, then the Optionee shall have a period of twelve (12) months
         following the date of such cessation of Service during which to
         exercise each outstanding option held by such Optionee.

                           (iii) If the Optionee dies while holding an
         outstanding option, then the personal representative of his or her
         estate or the person or persons to whom the option is transferred
         pursuant to the Optionee's will or the laws of inheritance shall have a
         twelve (12)-month period following the date of the Optionee's death to
         exercise such option.

                           (iv) Under no circumstances, however, shall any such
         option be exercisable after the specified expiration of the option
         term.

                           (v) During the applicable post-Service exercise
         period, the option may not be exercised in the aggregate for more than
         the number of vested shares for which the option is exercisable on the
         date of the Optionee's cessation of Service. Upon the expiration of the
         applicable exercise period or (if earlier) upon the expiration of the
         option term, the option shall terminate and cease to be outstanding for
         any vested shares for which the option has not been exercised. However,
         the option shall, immediately upon the Optionee's cessation of Service,
         terminate and cease to be outstanding with respect to any and all
         option shares for which the option is not otherwise at the time
         exercisable or in which the Optionee is not otherwise at that time
         vested.

                                       5
<PAGE>   6

                           (vi) Should Optionee's Service be terminated for
         Misconduct or should Optionee otherwise engage in Misconduct while
         holding one or more outstanding options under the Plan, then all those
         options shall terminate immediately and cease to remain outstanding.

                  2. The Plan Administrator shall have the discretion,
exercisable either at the time an option is granted or at any time while the
option remains outstanding, to:

                           (i) extend the period of time for which the option is
         to remain exercisable following Optionee's cessation of Service or
         death from the limited period otherwise in effect for that option to
         such greater period of time as the Plan Administrator shall deem
         appropriate, but in no event beyond the expiration of the option term,
         and/or

                           (ii) permit the option to be exercised, during the
         applicable post-Service exercise period, not only with respect to the
         number of vested shares of Common Stock for which such option is
         exercisable at the time of the Optionee's cessation of Service but also
         with respect to one or more additional installments in which the
         Optionee would have vested under the option had the Optionee continued
         in Service.

                  D. STOCKHOLDER RIGHTS. The holder of an option shall have no
stockholder rights with respect to the shares subject to the option until such
person shall have exercised the option, paid the exercise price and become the
recordholder of the purchased shares.

                  E. UNVESTED SHARES. The Plan Administrator shall have the
discretion to grant options which are exercisable for unvested shares of Common
Stock. Should the Optionee cease Service while holding such unvested shares, the
Corporation shall have the right to repurchase, at the exercise price paid per
share, any or all of those unvested shares. The terms upon which such repurchase
right shall be exercisable (including the period and procedure for exercise and
the appropriate vesting schedule for the purchased shares) shall be established
by the Plan Administrator and set forth in the document evidencing such
repurchase right. The Plan Administrator may not impose a vesting schedule upon
any option grant or the shares of Common Stock subject to that option which is
more restrictive than twenty percent (20%) per year vesting, with the initial
vesting to occur not later than one (1) year after the option grant date.
However, such limitation shall not be applicable to any option grants made to
individuals who are officers of the Corporation, non-employee Board members or
independent consultants.

                  F. FIRST REFUSAL RIGHTS. Until such time as the Common Stock
is first registered under Section 12 of the 1934 Act, the Corporation shall have
the right of first refusal with respect to any proposed disposition by the
Optionee (or any successor in interest) of any shares of Common Stock issued
under the Plan. Such right of first refusal shall be exercisable in accordance
with the terms established by the Plan Administrator and set forth in the
document evidencing such right.

                                       6
<PAGE>   7

                  G. LIMITED TRANSFERABILITY OF OPTIONS. During the lifetime of
the Optionee, the option shall be exercisable only by the Optionee and shall not
be assignable or transferable other than by will or by the laws of inheritance
following the Optionee's death.

         II.      INCENTIVE OPTIONS

                  The terms specified below shall be applicable to all Incentive
Options. Except as modified by the provisions of this Section II, all the
provisions of Articles One, Two and Four shall be applicable to Incentive
Options. Options which are specifically designated as Non-Statutory Options
shall not be subject to the terms of this Section II.

                  A. ELIGIBILITY. Incentive Options may only be granted to
Employees.

                  B. EXERCISE PRICE. The exercise price per share shall not be
less than one hundred percent (100%) of the Fair Market Value per share of
Common Stock on the option grant date.

                  C. DOLLAR LIMITATION. The aggregate Fair Market Value of the
shares of Common Stock (determined as of the respective date or dates of grant)
for which one or more options granted to any Employee under the Plan (or any
other option plan of the Corporation or any Parent or Subsidiary) may for the
first time become exercisable as Incentive Options during any one (1) calendar
year shall not exceed the sum of One Hundred Thousand Dollars ($100,000). To the
extent the Employee holds two (2) or more such options which become exercisable
for the first time in the same calendar year, the foregoing limitation on the
exercisability of such options as Incentive Options shall be applied on the
basis of the order in which such options are granted.

                  D. 10% STOCKHOLDER. If any Employee to whom an Incentive
Option is granted is a 10% Stockholder, then the option term shall not exceed
five (5) years measured from the option grant date.

         III.     CORPORATE TRANSACTION

                  A. The shares subject to each option outstanding under the
Plan at the time of a Corporate Transaction shall automatically vest in full so
that each such option shall, immediately prior to the effective date of the
Corporate Transaction, become exercisable for all of the shares of Common Stock
at the time subject to that option and may be exercised for any or all of those
shares as fully-vested shares of Common Stock. However, the shares subject to an
outstanding option shall NOT vest on such an accelerated basis if and to the
extent: (i) such option is assumed by the successor corporation (or parent
thereof) in the Corporate Transaction and any repurchase rights of the
Corporation with respect to the unvested option shares are concurrently assigned
to such successor corporation (or parent thereof) or (ii) such option is to be
replaced with a cash incentive program of the successor corporation which
preserves the spread existing on the unvested option shares at the time of the
Corporate Transaction and

                                       7
<PAGE>   8

provides for subsequent payout in accordance with the same vesting schedule
applicable to those unvested option shares or (iii) the acceleration of such
option is subject to other limitations imposed by the Plan Administrator at the
time of the option grant.

                  B. All outstanding repurchase rights shall also terminate
automatically, and the shares of Common Stock subject to those terminated rights
shall immediately vest in full, in the event of any Corporate Transaction,
except to the extent: (i) those repurchase rights are assigned to the successor
corporation (or parent thereof) in connection with such Corporate Transaction or
(ii) such accelerated vesting is precluded by other limitations imposed by the
Plan Administrator at the time the repurchase right is issued.

                  C. Immediately following the consummation of the Corporate
Transaction, all outstanding options shall terminate and cease to be
outstanding, except to the extent assumed by the successor corporation (or
parent thereof).

                  D. Each option which is assumed in connection with a Corporate
Transaction shall be appropriately adjusted, immediately after such Corporate
Transaction, to apply to the number and class of securities which would have
been issuable to the Optionee in consummation of such Corporate Transaction, had
the option been exercised immediately prior to such Corporate Transaction.
Appropriate adjustments shall also be made to (i) the number and class of
securities available for issuance under the Plan following the consummation of
such Corporate Transaction and (ii) the exercise price payable per share under
each outstanding option, PROVIDED the aggregate exercise price payable for such
securities shall remain the same. To the extent the actual holders of the
Corporation's outstanding Common Stock receive cash consideration for their
Common Stock in consummation of the Corporate Transaction, the successor
corporation may, in connection with the assumption of the outstanding options
under this Plan, substitute one or more shares of its own common stock with a
fair market value equivalent to the cash consideration paid per share of Common
Stock in such Corporate Transaction.

                  E. The Plan Administrator shall have the discretion,
exercisable either at the time the option is granted or at any time while the
option remains outstanding, to structure one or more options so that those
options shall automatically accelerate and vest in full (and any repurchase
rights of the Corporation with respect to the unvested shares subject to those
options shall immediately terminate) upon the occurrence of a Corporate
Transaction, whether or not those options are to be assumed in the Corporate
Transaction.

                  F. The Plan Administrator shall also have full power and
authority, exercisable either at the time the option is granted or at any time
while the option remains outstanding, to structure such option so that the
shares subject to that option will automatically vest on an accelerated basis
should the Optionee's Service terminate by reason of an Involuntary Termination
within a designated period (not to exceed eighteen (18) months) following the
effective date of any Corporate Transaction in which the option is assumed and
the repurchase rights applicable to those shares do not otherwise terminate. Any
option so accelerated shall remain exercisable for the fully-vested option
shares until the expiration or sooner termination of the option term. In
addition, the Plan Administrator may provide that one or more of the

                                       8
<PAGE>   9

Corporation's outstanding repurchase rights with respect to shares held by the
Optionee at the time of such Involuntary Termination shall immediately terminate
on an accelerated basis, and the shares subject to those terminated rights shall
accordingly vest at that time.

                  G. The portion of any Incentive Option accelerated in
connection with a Corporate Transaction shall remain exercisable as an Incentive
Option only to the extent the applicable One Hundred Thousand Dollar limitation
is not exceeded. To the extent such dollar limitation is exceeded, the
accelerated portion of such option shall be exercisable as a Non-Statutory
Option under the Federal tax laws.

                  H. The grant of options under the Plan shall in no way affect
the right of the Corporation to adjust, reclassify, reorganize or otherwise
change its capital or business structure or to merge, consolidate, dissolve,
liquidate or sell or transfer all or any part of its business or assets.

         IV.      CANCELLATION AND REGRANT OF OPTIONS

                  The Plan Administrator shall have the authority to effect, at
any time and from time to time, with the consent of the affected option holders,
the cancellation of any or all outstanding options under the Plan and to grant
in substitution therefor new options covering the same or different number of
shares of Common Stock but with an exercise price per share based on the Fair
Market Value per share of Common Stock on the new option grant date.

                                 ARTICLE THREE

                             STOCK ISSUANCE PROGRAM

         I.       STOCK ISSUANCE TERMS

                  Shares of Common Stock may be issued under the Stock Issuance
Program through direct and immediate issuances without any intervening option
grants. Each such stock issuance shall be evidenced by a Stock Issuance
Agreement which complies with the terms specified below.

               A. PURCHASE PRICE.

                  1. The purchase price per share shall be fixed by the Plan
Administrator but shall not be less than eighty-five percent (85%) of the Fair
Market Value per share of Common Stock on the issue date. However, the purchase
price per share of Common Stock issued to a 10% Stockholder shall not be less
than one hundred and ten percent (110%) of such Fair Market Value.

                  2. Subject to the provisions of Section I of Article Four,
shares of Common Stock may be issued under the Stock Issuance Program for any of
the following items of consideration which the Plan Administrator may deem
appropriate in each individual instance:

                           (i) cash or check made payable to the Corporation, or

                           (ii) past services rendered to the Corporation (or
         any Parent or Subsidiary).

               B. VESTING PROVISIONS.

                  1. Shares of Common Stock issued under the Stock Issuance
Program may, in the discretion of the Plan Administrator, be fully and
immediately vested upon issuance or may vest in one or more installments over
the Participant's period of Service or upon attainment of specified performance
objectives. However, the Plan Administrator may not impose a vesting schedule
upon any stock issuance effected under the Stock Issuance Program which is more
restrictive than twenty percent (20%) per year vesting, with initial vesting to
occur not later than one (1) year after the issuance date. Such limitation shall
not apply to any Common Stock issuances made to the officers of the Corporation,
non-employee Board members or independent consultants.

                  2. Any new, substituted or additional securities or other
property (including money paid other than as a regular cash dividend) which the
Participant may have the right to receive with respect to the Participant's
unvested shares of Common Stock by reason of any stock dividend, stock split,
recapitalization, combination of shares, exchange of shares or other change
affecting the outstanding Common Stock as a class without the Corporation's

                                       10
<PAGE>   11

receipt of consideration shall be issued subject to (i) the same vesting
requirements applicable to the Participant's unvested shares of Common Stock and
(ii) such escrow arrangements as the Plan Administrator shall deem appropriate.

                  3. The Participant shall have full stockholder rights with
respect to any shares of Common Stock issued to the Participant under the Stock
Issuance Program, whether or not the Participant's interest in those shares is
vested. Accordingly, the Participant shall have the right to vote such shares
and to receive any regular cash dividends paid on such shares.

                  4. Should the Participant cease to remain in Service while
holding one or more unvested shares of Common Stock issued under the Stock
Issuance Program or should the performance objectives not be attained with
respect to one or more such unvested shares of Common Stock, then those shares
shall be immediately surrendered to the Corporation for cancellation, and the
Participant shall have no further stockholder rights with respect to those
shares. To the extent the surrendered shares were previously issued to the
Participant for consideration paid in cash or cash equivalent (including the
Participant's purchase-money indebtedness), the Corporation shall repay to the
Participant the cash consideration paid for the surrendered shares and shall
cancel the unpaid principal balance of any outstanding purchase-money note of
the Participant attributable to such surrendered shares.

                  5. The Plan Administrator may in its discretion waive the
surrender and cancellation of one or more unvested shares of Common Stock (or
other assets attributable thereto) which would otherwise occur upon the
non-completion of the vesting schedule applicable to those shares. Such waiver
shall result in the immediate vesting of the Participant's interest in the
shares of Common Stock as to which the waiver applies. Such waiver may be
effected at any time, whether before or after the Participant's cessation of
Service or the attainment or non-attainment of the applicable performance
objectives.

                  6. FIRST REFUSAL RIGHTS. Until such time as the Common Stock
is first registered under Section 12 of the 1934 Act, the Corporation shall have
the right of first refusal with respect to any proposed disposition by the
Participant (or any successor in interest) of any shares of Common Stock issued
under the Stock Issuance Program. Such right of first refusal shall be
exercisable in accordance with the terms established by the Plan Administrator
and set forth in the document evidencing such right.

         II.      CORPORATE TRANSACTION

                  A. Upon the occurrence of a Corporate Transaction, all
outstanding repurchase rights under the Stock Issuance Program shall terminate
automatically, and the shares of Common Stock subject to those terminated rights
shall immediately vest in full, except to the extent: (i) those repurchase
rights are assigned to the successor corporation (or parent thereof) in
connection with such Corporate Transaction or (ii) such accelerated vesting is
precluded by other limitations imposed by the Plan Administrator at the time the
repurchase right is issued.

                                       11
<PAGE>   12

                  B. The Plan Administrator shall have the discretionary
authority, exercisable either at the time the unvested shares are issued or any
time while the Corporation's repurchase rights with respect to those shares
remain outstanding, to provide that those rights shall automatically terminate
on an accelerated basis, and the shares of Common Stock subject to those
terminated rights shall immediately vest, in the event the Participant's Service
should subsequently terminate by reason of an Involuntary Termination within a
designated period (not to exceed eighteen (18) months) following the effective
date of any Corporate Transaction in which those repurchase rights are assigned
to the successor corporation (or parent thereof).

         III.     SHARE ESCROW/LEGENDS

                  Unvested shares may, in the Plan Administrator's discretion,
be held in escrow by the Corporation until the Participant's interest in such
shares vests or may be issued directly to the Participant with restrictive
legends on the certificates evidencing those unvested shares.

                                  MISCELLANEOUS

         I.       FINANCING

                  The Plan Administrator may permit any Optionee or Participant
to pay the option exercise price under the Option Grant Program or the purchase
price for shares issued under the Stock Issuance Program by delivering a
full-recourse, interest bearing promissory note payable in one or more
installments and secured by the purchased shares. In no event, however, may the
maximum credit available to the Optionee or Participant exceed the sum of (i)
the aggregate option exercise price or purchase price payable for the purchased
shares (less the par value of those shares) plus (ii) any Federal, state and
local income and employment tax liability incurred by the Optionee or the
Participant in connection with the option exercise or share purchase.

         II.      EFFECTIVE DATE AND TERM OF PLAN

                  A. The Plan shall become effective when adopted by the Board,
but no option granted under the Plan may be exercised, and no shares shall be
issued under the Plan, until the Plan is approved by the Corporation's
stockholders. If such stockholder approval is not obtained within twelve (12)
months after the date of the Board's adoption of the Plan, then all options
previously granted under the Plan shall terminate and cease to be outstanding,
and no further options shall be granted and no shares shall be issued under the
Plan. Subject to such limitation, the Plan Administrator may grant options and
issue shares under the Plan at any time after the effective date of the Plan and
before the date fixed herein for termination of the Plan.

                  B. The Plan shall terminate upon the EARLIEST of (i) the
expiration of the ten (10)-year period measured from the date the Plan is
adopted by the Board, (ii) the date on which all shares available for issuance
under the Plan shall have been issued as vested shares or (iii) the termination
of all outstanding options in connection with a Corporate Transaction. All
options and unvested stock issuances outstanding at the time of a clause (i)
termination event shall continue to have full force and effect in accordance
with the provisions of the documents evidencing those options or issuances.

         III.     AMENDMENT OF THE PLAN

                  A. The Board shall have complete and exclusive power and
authority to amend or modify the Plan in any or all respects. However, no such
amendment or modification shall adversely affect the rights and obligations with
respect to options or unvested stock issuances at the time outstanding under the
Plan unless the Optionee or the Participant consents to such amendment or
modification. In addition, certain amendments may require stockholder approval
pursuant to applicable laws and regulations.

                                       13
<PAGE>   14

                  B. Options may be granted under the Option Grant Program and
shares may be issued under the Stock Issuance Program which are in each instance
in excess of the number of shares of Common Stock then available for issuance
under the Plan, provided any excess shares actually issued under those programs
shall be held in escrow until there is obtained stockholder approval of an
amendment sufficiently increasing the number of shares of Common Stock available
for issuance under the Plan. If such stockholder approval is not obtained within
twelve (12) months after the date the first such excess grants or issuances are
made, then (i) any unexercised options granted on the basis of such excess
shares shall terminate and cease to be outstanding and (ii) the Corporation
shall promptly refund to the Optionees and the Participants the exercise or
purchase price paid for any excess shares issued under the Plan and held in
escrow, together with interest (at the applicable Short Term Federal Rate) for
the period the shares were held in escrow, and such shares shall thereupon be
automatically cancelled and cease to be outstanding.

         IV.      USE OF PROCEEDS

                  Any cash proceeds received by the Corporation from the sale of
shares of Common Stock under the Plan shall be used for general corporate
purposes.

         V.       WITHHOLDING

                  The Corporation's obligation to deliver shares of Common Stock
upon the exercise of any options granted under the Plan or upon the issuance or
vesting of any shares issued under the Plan shall be subject to the satisfaction
of all applicable Federal, state and local income and employment tax withholding
requirements.

         VI.      REGULATORY APPROVALS

                  The implementation of the Plan, the granting of any options
under the Plan and the issuance of any shares of Common Stock (i) upon the
exercise of any option or (ii) under the Stock Issuance Program shall be subject
to the Corporation's procurement of all approvals and permits required by
regulatory authorities having jurisdiction over the Plan, the options granted
under it and the shares of Common Stock issued pursuant to it.

         VII.     NO EMPLOYMENT OR SERVICE RIGHTS

                  Nothing in the Plan shall confer upon the Optionee or the
Participant any right to continue in Service for any period of specific duration
or interfere with or otherwise restrict in any way the rights of the Corporation
(or any Parent or Subsidiary employing or retaining such person) or of the
Optionee or the Participant, which rights are hereby expressly reserved by each,
to terminate such person's Service at any time for any reason, with or without
cause.

connection with the Corporation (or any Parent or Subsidiary) assure such
individual access to equivalent information.

         Executive may voluntarily terminate his employment relationship at any
         time for any reason upon thirty (30) days' prior written notice to the

                  (C) TERMINATION WITHOUT CAUSE. During the Agreement Term, the
         Company may terminate the employment of the Executive at any time for
         any reason other than Cause upon thirty (30) days' prior written notice

         months of base salary, less payroll deductions and required

         continuation of all Company Benefits for a period of six (6) months.

                  (D) DISABILITY. During the Agreement Term, the Company may

         for the calendar year pro-rated based upon the number of full months
         Executive was employed in such year, and (iv) continuation of all
         Company Benefits for a period of four (4) months.

                  For purposes of this Agreement, "DISABILITY" shall mean a

         duties under this Agreement for a period of at least 90 consecutive
         days or 180 non-consecutive days within any 365-day period. Any
         question as to the existence of the Disability of Executive as to which
         Executive and the Company cannot agree shall be determined in writing

         and the Company. If Executive and the Company cannot agree as to a
         qualified independent physician, each shall appoint such a physician
         and those two physicians shall select a third who shall make such
         determination in writing. The determination of Disability made in
         writing to the Company and Executive shall be final and conclusive for
         all purposes of this Agreement.

                  (E) DEATH. In the event of the death of the Executive during
         the Agreement Term, this Agreement shall automatically terminate
         (subject to Section 8.9), such termination to be effective on the date
         of Executive's death, and the Company shall pay to Executive or his
         heirs, executors or administrators, his Accrued Rights, a portion of a
         discretionary bonus, if any, which may otherwise have been paid to
         Executive pursuant to Section 2.2 hereof with respect to the annual
         period in which the death occurs pro-rated based upon the number of
         full months Executive was employed in such annual period prior to his
         death.
