                         THE NEIMAN MARCUS GROUP, INC.

                              1997 INCENTIVE PLAN

1.  DEFINED TERMS

     Appendix A, which is incorporated by reference, defines the terms used in
the Plan.

2.  IN GENERAL

     The Plan has been established to advance the interests of the Company by
giving selected Employees, directors and other persons (including both
individuals and entities) who provide services to the Company or its Affiliates
equity-based or cash incentives through the grant of Awards. No Award may be
granted under the Plan after September 1, 2006, but Awards previously granted
may extend beyond that date.

3.  ADMINISTRATION

     The Administrator has discretionary authority, subject only to the express
provisions of the Plan, to interpret the Plan; determine eligibility for and
grant Awards; determine, modify or waive the terms and conditions of any Award;
prescribe forms, rules and procedures (which it may modify or waive); and
otherwise do all things necessary to carry out the purposes of the Plan. Once an
Award has been communicated in writing to a Participant, the Administrator may
not, without the Participant's consent, alter the terms of the Award so as to
affect adversely the Participant's rights under the Award, unless the
Administrator expressly reserved the right to do so. In the case of any Award
intended to be eligible for the performance-based compensation exception under
Section 162(m)(4)(C) of the Code, the Committee shall exercise its discretion
consistent with qualifying the Award for such exception.

4.  SHARES SUBJECT TO THE PLAN

     A.  A total of 4,900,000 shares of Stock have been reserved for issuance
under the Plan. The following shares of Stock will also be available for future
grants:

        (i) shares remaining under an Award that terminates without having been
            exercised in full (in the case of an Award requiring exercise by a
            Participant for delivery of Stock);

        (ii) shares subject to an Award, where cash is delivered to a
             Participant in lieu of such shares;

        (iii) shares of Restricted Stock that are forfeited to the Company;

        (iv) shares of Stock tendered by a Participant as payment upon exercise
             of an Award; and

        (v) shares of Stock held back by the Administrator, or tendered by a
            Participant, in satisfaction of tax withholding requirements.

Stock delivered under the Plan may be authorized but unissued Stock or
previously issued Stock acquired by the Company and held in treasury. No
fractional shares of Stock will be delivered under the Plan.

     B.  The maximum number of shares for which Stock Options may be granted to
any person over the life of the Plan shall be 1,000,000. The maximum number of
shares subject to SARs granted to any person over the life of the Plan shall
likewise be 1,000,000. For purposes of the preceding two sentences, the
repricing of a Stock Option or SAR shall be treated as a new grant to the extent
required

                                       A-1
<PAGE>   2

under Section 162(m) of the Code. The aggregate maximum number of shares of
Stock delivered to any person over the life of the Plan pursuant to Awards that
are not Stock Options or SARs shall also be 1,000,000. Subject to these
limitations, each person eligible to participate in the Plan shall be eligible
in any year to receive Awards covering up to the full number of shares then
available for Awards under the Plan.

5.  ELIGIBILITY AND PARTICIPATION

     The Administrator will select Participants from among those key Employees,
directors and other individuals or entities providing services to the Company or
its Affiliates who, in the opinion of the Administrator, are in a position to
make a significant contribution to the success of the Company and its
Affiliates. Eligibility for ISOs is further limited to those individuals whose
employment status would qualify them for the tax treatment described in Sections
421 and 422 of the Code.

6.  RULES APPLICABLE TO AWARDS

     a.  ALL AWARDS

        (1)  Performance Objectives.  Where rights under an Award depend in
whole or in part on attainment of performance objectives, actions by the Company
that have an effect, however material, on such performance objectives or on the
likelihood that they will be achieved will not be deemed an amendment or
alteration of the Award unless accomplished by a change in the express terms of
the Award or other action that is without substantial consequence except as it
affects the Award.

        (2)  Alternative Settlement.  The Company retains the right at any time
to extinguish rights under an Award in exchange for payment in cash, Stock
(subject to the limitations of Section 4) or other property on such terms as the
Administrator determines, provided the holder of the Award consents to such
exchange.

        (3)  Transferability Of Awards.  Except as the Administrator otherwise
expressly provides, Awards (other than an Award in the form of an outright
transfer of cash or Unrestricted Stock) may not be transferred other than by
will or by the laws of descent and distribution and, during a Participant's
lifetime an Award requiring exercise may be exercised only by the Participant
(or in the event of the Participant's incapacity, the person or persons legally
appointed to act on the Participant's behalf).

        (4)  Vesting, Etc.  The Administrator may determine the time or times at
which an Award will vest (i.e., become free of restrictions) or become
exercisable. Unless the Administrator expressly provides otherwise, an Award
requiring exercise will cease to be exercisable, and all other Awards to the
extent not already fully vested will be forfeited, immediately upon the
cessation (for any reason, including death) of the Participant's employment or
other service relationship with the Company and its Affiliates.

        (5)  Taxes.  The Administrator will make such provision for the
withholding of taxes as it deems necessary. The Administrator may, but need not,
hold back shares from an Award or permit a Participant to tender previously
owned shares in satisfaction of tax withholding requirements.

        (6)  Dividend Equivalents, Etc.  The Administrator may provide for the
payment of amounts in lieu of dividends or other distributions with respect to
Stock subject to an Award.

        (7)  Rights Limited.  Nothing in the Plan shall be construed as giving
any person the right to continued employment or service with the Company or its
Affiliates, nor any rights as a shareholder except as to shares actually issued
under the Plan. The loss of existing or potential profit in Awards will not
constitute an element of damages in the event of termination of employment or
service for any

                                       A-2
<PAGE>   3

reason, even if the termination is in violation of an obligation of the Company
or Affiliate to the Participant.

        (8)  Section 162(m).  In the case of an Award intended to be eligible
for the performance-based compensation exception under Section 162(m)(4)(C) of
the Code, the Plan and such Award shall be construed in a manner consistent with
qualifying the Award for such exception.

     b.  AWARDS REQUIRING EXERCISE

        (1)  Time And Manner Of Exercise.  Unless the Administrator expressly
provides otherwise, (a) an Award requiring exercise by the holder will not be
deemed to have been exercised until the Administrator receives a written notice
of exercise (in form acceptable to the Administrator) signed by the appropriate
person and accompanied by any payment required under the Award; and (b) if the
Award is exercised by any person other than the Participant, the Administrator
may require satisfactory evidence that the person exercising the Award has the
right to do so.

        (2)  Payment Of Exercise Price, If Any.  Where the exercise of an Award
is to be accompanied by payment, the Administrator may determine the required or
permitted forms of payment either at or after the time of the Award, subject to
the following: (a) unless the Administrator expressly provides otherwise, all
payments will be by cash or check acceptable to the Administrator; and (b) where
shares issued under an Award are part of an original issue of shares, the Award
shall require an exercise price equal to at least the par value of such shares.

        (3)  Reload Awards.  The Administrator may provide that upon the
exercise of an Award through the tender of previously owned shares of Stock, the
Participant or other person exercising the Award will automatically receive a
new Award of like kind covering a number of shares determined by reference to
the number of shares tendered in payment of the exercise price of the first
Award.

     c.  AWARDS NOT REQUIRING EXERCISE

     Awards of Restricted Stock and Unrestricted Stock may be made in return for
either (i) services determined by the Administrator to have a value not less
than the par value of the awarded shares, or (ii) cash or other property having
a value not less than the par value of the awarded shares plus such additional
amounts (if any) as the Administrator may determine payable in such combination
of cash, other property (of any kind) or services as the Administrator may
determine.

7.  EFFECT OF CERTAIN TRANSACTIONS

     a.  MERGERS, ETC.

     In the event of a consolidation or merger in which the Company is not the
surviving corporation or which results in the acquisition of substantially all
the Company's outstanding Stock by a single person or entity or by a group of
persons and/or entities acting in concert, or in the event of the sale or
transfer of substantially all the Company's assets or a dissolution or
liquidation of the Company (a "covered transaction"), all outstanding Awards
requiring exercise will cease to be exercisable, and all other Awards to the
extent not fully vested (including Awards subject to performance conditions not
yet satisfied or determined) will be forfeited, as of the effective time of the
covered transaction. Prior to such time the Administrator may (but need not)
accelerate the vesting or exercisability of any Award or provide for substitute
or replacement awards from the acquiring entity (if any).

                                       A-3
<PAGE>   4

     b.  CHANGES IN AND DISTRIBUTIONS WITH RESPECT TO THE STOCK

        (1)  Basic Antidilution Provisions.  In the event of a stock dividend,
stock split or combination of shares, recapitalization or other change in the
Company's capital structure, the Administrator will make appropriate adjustments
to the maximum number of shares that may be delivered under the Plan under
Section 4.a. and to the maximum share limits described in Section 4.b., and will
also make appropriate adjustments to the number and kind of shares of stock or
securities subject to Awards then outstanding or subsequently granted, any
exercise prices relating to Awards and any other provision of Awards affected by
such change.

        (2)  Certain Other Adjustments.  The Administrator may also make
adjustments of the type described in paragraph (1) above to take into account
distributions to common stockholders other than stock dividends or normal cash
dividends, mergers, consolidations, acquisitions, dispositions or similar
corporate transactions, or any other event, if the Administrator determines that
adjustments are appropriate to avoid distortion in the operation of the Plan and
to preserve the value of Awards made hereunder; provided, that no such
adjustment shall be made to the maximum share limits described in Section 4.b.,
or otherwise to an Award intended to be eligible for the performance-based
exception under Section 162(m)(4)(C) of the Code, except to the extent
consistent with that exception.

     c.  CHANGE OF CONTROL

     Notwithstanding anything to the contrary in this Plan and unless
specifically provided otherwise in the Award Agreement at the time an Award is
granted, upon any Change of Control of the Company, any time periods, conditions
or contingencies relating to the exercise or realization of, or lapse of
restrictions under, any Award shall be automatically accelerated or waived so
that the Award may be exercised or realized in full; provided that, in the event
of a Change of Control that is intended to qualify for pooling of interests
accounting, the foregoing provisions of this paragraph shall be of no force and
effect if implementation of such provisions would preclude the Change of Control
from so qualifying and, in such event, the Committee shall take whatever action
it deems appropriate to enable holders of Awards to realize a substantially
similar economic result as would have been realized by acceleration of Awards
but without precluding the Change of Control from qualifying as a pooling of
interests.

A Change of Control will occur for purposes of this Plan:

    (i)   upon the consummation of any transaction or series of transactions
under which the Company is merged or consolidated with any other company, other
than a merger or consolidation which would result in the shareholders of the
Company immediately prior thereto continuing to own (either by remaining
outstanding or by being converted into voting securities of the surviving
entity) more than 50% of the combined voting power of the voting securities of
the Company, the acquiring entity or such surviving entity outstanding
immediately after such merger or consolidation in substantially the same
proportion such shareholders held the voting securities of the Company
immediately prior to the merger or consolidation;

    (ii)  if any person or group (as used in section 13(d) of the Securities
 Exchange Act of 1934, as amended (the "Exchange Act")) (other than the Company,
any trustee or other fiduciary holding securities under an employee benefit plan
of the Company, or any company owned, directly or indirectly, by the
shareholders of the Company in substantially the same proportions as their
ownership of stock of the Company) becomes the "beneficial owner" (as defined in
Rule 13d-3 under the Exchange Act) of securities of the Company representing
more than 40% of (a) the shares of the Company's Class B Common Stock then
outstanding or (b) the total voting power (other than in the election of
directors) of all securities of the Company then outstanding; or

    (iii) if, during any period of twenty-four consecutive months, individuals
who at the beginning of such period constitute the Board of Directors, and any
director whose election or nomination for election by the Company's shareholders
was approved by a vote of at least two-thirds (2/3) of the directors then still
in office who either were directors at the beginning of the period or whose
election or nomination for election was previously so approved, cease for any
reason (other than death or disability) to constitute at least a majority
thereof; or

    (iv)  the complete liquidation of the Company or the sale or disposition by
the Company of all or substantially all of the Company's assets, other than a
liquidation of the Company into a wholly-owned subsidiary.

8.  CONDITIONS ON DELIVERY OF STOCK

     The Company will not be obligated to deliver any shares of Stock pursuant
to the Plan or to remove any restriction from shares previously delivered under
the Plan until: the Company's counsel has approved all legal matters in
connection with the issuance and delivery of such shares; if the outstanding
Stock is at the time listed on any stock exchange or national market system, the
shares to be delivered have been listed or authorized to be listed on such
exchange or system upon official notice of notice of issuance; and all
conditions of the Award have been satisfied or waived. If the sale of Stock has
not been registered under the Securities Act of 1933, as amended, the Company
may require, as a condition to exercise of the Award, such representations or
agreements as counsel for the Company may consider appropriate to avoid
violation of such Act. The Company may require that certificates evidencing
Stock issued under the Plan bear an appropriate legend reflecting any
restriction on transfer applicable to such Stock.

9.  AMENDMENT AND TERMINATION

     Subject to the last sentence of Section 3, the Administrator may at any
time or times amend the Plan or any outstanding Award for any purpose which may
at the time be permitted by law, or may at any time terminate the Plan as to any
further grants of Awards, provided that (except to the extent expressly required
or permitted by the Plan) no such amendment will, without the approval of the
stockholders of the Company, effectuate a change for which stockholder approval
is required in order for the Plan to continue to qualify under Section 422 of
the Code or for Awards to be eligible for the performance-based exception under
Section 162(m)(4)(C) of the Code.

10.  NON-LIMITATION OF THE COMPANY'S RIGHTS

     The existence of the Plan or the grant of any Award shall not in any way
affect the Company's right to award a person bonuses or other compensation in
addition to Awards under the Plan.

11.  GOVERNING LAW

     The Plan shall be construed in accordance with the laws of The Commonwealth
of Massachusetts.

                                   APPENDIX A

                              DEFINITION OF TERMS

     The following terms, when used in the Plan, shall have the meanings and be
subject to the provisions set forth below:

     "Administrator":  The Committee, if one has been appointed; otherwise the
Board.

     "Affiliate":  Any corporation or other entity owning, directly or
indirectly, 50% or more of the outstanding Stock of the Company, or in which the
Company or any such corporation or other entity owns, directly or indirectly,
50% of the outstanding capital stock (determined by aggregate voting rights) or
other voting interests.

     "Award":  Any of the following:

          (i)  Options ("Stock Options") entitling the recipient to acquire
     shares of Stock upon payment of the exercise price. Each Stock Option
     (except as otherwise expressly provided by the Committee consistent with
     continued qualification of the Stock Option as a performance-based award
     for purposes of Section 162(m) of the Code, or unless the Committee
     expressly determines that such Stock Option is not subject to Section
     162(m) of the Code or that the Stock Option is not intended to qualify for
     the performance-based exception under Section 162(m) of the Code), will
     have an exercise price not less than the fair market value of the Stock
     subject to the option, determined as of the date of grant, except that an
     ISO granted to an Employee described in Section 422(b)(6) of the Code will
     have an exercise price not less than 110% of such fair market value. The
     Administrator will determine the medium in which the exercise price is to
     be paid, the duration of the option, the time or times at which an option
     will become exercisable, provisions for continuation (if any) of option
     rights following termination of the Participant's employment with the
     Company and its Affiliates, and all other terms of the Option. No Stock
     Option awarded under the Plan will be an ISO unless the Administrator
     expressly provides for ISO treatment.

          (ii)  Rights ("SARs") entitling the holder upon exercise to receive
     cash or Stock, as the Administrator determines, equal to a function
     (determined by the Administrator using such factors as it deems
     appropriate) of the amount by which the Stock has appreciated in value
     since the date of the Award.

          (iii)  Stock subject to restrictions ("Restricted Stock") under the
     Plan requiring that the Stock be redelivered to the Company if specified
     conditions are not satisfied. The conditions to be satisfied in connection
     with any Award of Restricted Stock, the terms on which such Stock must be
     redelivered to the Company, the purchase price of such Stock, and all other
     terms shall be determined by the Administrator.

          (iv)  Stock not subject to any restrictions under the Plan
     ("Unrestricted Stock").

          (v)  A promise to deliver Stock or other securities in the future on
     such terms and conditions as the Administrator determines.

          (vi)  Securities (other than Stock Options) that are convertible into
     or exchangeable for Stock on such terms and conditions as the Administrator
     determines.

                                       A-5
<PAGE>   6

          (vii)  Cash bonuses tied to performance criteria as described at
     (viii) below ("Cash Performance Awards").

          (viii)  Awards described in any of (i) through (vii) above where the
     right to exercisability, vesting or full enjoyment of the Award is
     conditioned in whole or in part on the satisfaction of specified
     performance criteria ("Performance Awards"). The Committee in its
     discretion may grant Performance Awards that are intended to qualify for
     the performance-based compensation exception under Section 162(m)(4)(C) of
     the Code and Performance Awards that are not intended so to qualify. No
     more than $2,000,000 may be paid to any individual with respect to any Cash
     Performance Award. In applying the limitation of the preceding sentence:
     (A) multiple Cash Performance Awards to the same individual that are
     determined by reference to performance periods of one year or less ending
     with or within the same fiscal year of the Company shall be subject in the
     aggregate to one $2,000,000 limit, and (B) multiple Cash Performance Awards
     to the same individual that are determined by reference to one or more
     multi-year performance periods ending in the same fiscal year of the
     Company shall be subject in the aggregate to a separate limit of
     $2,000,000. With respect to any Performance Award other than a Cash
     Performance Award, Stock Option or SAR, the maximum award opportunity shall
     be 1,000,000 shares or their equivalent value in cash, subject to the
     limitations of Section 4.b. For the avoidance of doubt, any Performance
     Award of a type described in (i) through (vi) above shall be treated for
     purposes of this paragraph as a Performance Award that is not a Cash
     Performance Award, even if payment is made in cash.

          In the case of a Performance Award intended to qualify as
     performance-based for the purposes of Section 162(m) of the Code, the
     Committee shall in writing preestablish a specific performance goal (based
     solely on one or more qualified performance criteria) no later than 90 days
     after the commencement of the period of service to which the performance
     relates (or at such earlier time as is required to qualify the award as
     performance-based under Code Section 162(m)(4)(C)). For purposes of the
     Plan, a qualified performance criterion is any of the following: (1)
     earnings or earnings per share (whether on a pre-tax, after-tax,
     operational or other basis), (2) return on equity, (3) return on assets,
     (4) revenues, (5) sales, (6) expenses, (7) one or more operating ratios,
     (8) stock price, (9) stockholder return, (10) market share, (11) cash flow,
     (12) inventory levels or inventory turn, (13) capital expenditures, (14)
     net borrowing, debt leverage levels or credit quality, (15) the
     accomplishment of mergers, acquisitions, dispositions, public offerings or
     similar extraordinary business transactions or (16) any combination of the
     foregoing. The performance goals selected in any case need not be
     applicable across the Company, but may be particular to an individual's
     function or business unit. Prior to payment of any Performance Award
     intended to qualify as performance-based under Section 162(m)(4)(C) of the
     Code, the Committee shall certify whether the performance goal has been
     attained and such determination shall be final and conclusive. If the
     performance goal is not attained, no other Award shall be provided in
     substitution of the Performance Award.

          (ix)  Grants of cash, or loans, made in connection with other Awards
     in order to help defray in whole or in part the economic cost (including
     tax cost) of the Award to the Participant. The terms of any such grant or
     loan shall be determined by the Administrator.

Awards may be combined in the Administrator's discretion.

     "Board":  The Board of Directors of the Company.

     "Code":  The U.S. Internal Revenue Code of 1986, as from time to time
amended and in effect.

                                       A-6
<PAGE>   7

     "Committee":  A committee of the Board comprised solely of two or more
outside directors within the meaning of Section 162(m) of the Code. The
Committee may delegate ministerial tasks to such persons (including Employees)
as it deems appropriate.

     "Company":  The Neiman Marcus Group, Inc.

     "Employee":  Any person who is employed by the Company or an Affiliate.

     "ISO":  A Stock Option intended to be an "incentive stock option" within
the meaning of Section 422 of the Code.

     "Participant":  An Employee, director or other person providing services to
the Company or its Affiliates who is granted an Award under the Plan.

     "Plan":  The Neiman Marcus Group, Inc. 1997 Incentive Plan as from time to
time amended and in effect.

     "Stock":  Common Stock of the Company, par value $.01 per share.

                                       A-7<PAGE>   1

than one registration on Form S-3 pursuant to the provisions of this Section 2.

     2.2  LIMITATION ON SHELF REGISTRATION OBLIGATION

     Notwithstanding the provisions of Section 2.1, and subject to the
limitations described below in this Section 2 and Section 3, Buyer shall not be
obligated to effect the filing of a Registration Statement pursuant to this

stockholders for such Registration Statement to be filed under the circumstances

                                      -20-

<PAGE>   4

Registration Statement, for a period of not more than 90 days; PROVIDED,

Statement filed pursuant to this Section 2 effective until November 30, 2000. If
Buyer utilizes the right set forth in this Section 2, the Registration Period
shall be extended for the number of days for which any filing was deferred as
specified in the notice; PROVIDED, HOWEVER, that the Registration Period need
not be extended pursuant to this subsection by a period of longer than six
months.

     2.3    SELLING PROCEDURES; SUSPENSION

     Each Holder of Registrable Securities agrees to give written notice to the
Buyer at least two (2) Business Days prior to any intended sale or distribution
of Registrable Securities under the Shelf Registration Statement referred to in
Section 2.1, which notice shall specify the date on which such Holder intends to
begin such sale or distribution. As soon as practicable after the date such
notice is received by Buyer, and in any event within two (2) Business Days after
such date, Buyer shall comply with either paragraph (a) or (b) below.

          (a) Unless paragraph (b) below applies, Buyer shall (i) if deemed
necessary by Buyer, prepare and file with the Commission a post-effective
amendment to the Shelf Registration Statement or a supplement to the related
Prospectus or a supplement or amendment to any document incorporated therein by
reference or file any other required document so that such Registration
Statement will not contain an untrue statement of a material fact or omit to
state a material fact required to be stated therein or necessary to make the
statements therein not misleading, and so that, as thereafter delivered to
purchasers of the Registrable Securities being sold thereunder, such Prospectus
will not contain an untrue statement of a material fact or omit to state a
material fact required to be stated therein or necessary to make the statements
therein, in light of the circumstances under which they were made, not
misleading; (ii) provide the Holders of the Registrable Securities who gave such
notice copies of any documents filed pursuant to Section 2.3(a)(i); and (iii)
inform each such Holder that Buyer has complied with its obligations in Section
2.3(a)(i) (or that, if Buyer has filed a post-effective amendment to the Shelf
Registration Statement which has not yet been declared effective, Buyer will
notify each such Holder to that effect, will use its reasonable efforts to
secure the effectiveness of such post-effective amendment and will immediately
notify each such Holder pursuant to Section 2.3(a)(i) hereof when the amendment
has become effective). Each Holder who has given notice of intention to
distribute such Holder's Registrable Securities in accordance with Section 2.3
hereof (a "NOTICE HOLDER") shall sell all or any of such Registrable Securities
pursuant to the Shelf Registration Statement and related Prospectus only during
the 90-day period commencing with the date on which Buyer gives notice, pursuant
to Section 2.3(a)(iii), that the Registration Statement and Prospectus may be
used for such purpose (such 90-day period is referred to as a "SELLING PERIOD").
The Notice Holders will not sell any Registrable Securities pursuant to such
Registration Statement or Prospectus after such Selling Period without giving a
new notice of intention to sell pursuant to

                                      -21-
<PAGE>   5

Section 2.3 hereof and receiving a further notice from Buyer pursuant to Section
2.3(a)(iii) hereof or paragraph (b) below.

          (b) In the event of (i) any request by the Commission or any other
federal or state governmental authority during the period of effectiveness of
the Shelf Registration Statement for amendments or supplements to a Shelf
Registration Statement or related Prospectus or for additional information; (ii)
the issuance by the Commission or any other federal or state governmental
authority of any stop order suspending the effectiveness of a Shelf Registration
Statement or the written threat or initiation of any proceedings for that
purpose; (iii) the receipt by Buyer of any notification with respect to the
suspension of the qualification or exemption from qualification of any of the
Registrable Securities for sale in any jurisdiction or the initiation or
threatening of any proceeding for such purpose; (iv) any event or circumstance
which necessitates the making of any changes in the Shelf Registration Statement
or Prospectus, or any document incorporated or deemed to be incorporated therein
by reference, so that, in the case of the Shelf Registration Statement, it will
not contain any untrue statement of a material fact or any omission to state a
material fact required to be stated therein or necessary to make the statements
therein not misleading, and that in the case of the Prospectus, it will not
contain any untrue statement of a material fact or any omission to state a
material fact required to be stated therein or necessary to make the statements
therein, in the light of the circumstances under which they were made, not
misleading; (v) that Buyer is in possession of material information that it
deems advisable not to disclose in a Registration Statement or (vi) that, in the
good faith judgment of Buyer's Board of Directors, it is advisable to suspend
use of the Prospectus (a "SUSPENSION") for a discrete period of time due to
pending corporate developments, public filings with the Commission or similar
events; then, subject to paragraph (d) below, Buyer shall deliver a certificate
in writing to the Notice Holders (the "SUSPENSION NOTICE") to the effect of the
foregoing and, upon receipt of such Suspension Notice, each such Notice Holder's
Selling Period will not commence until such Notice Holder's receipt of copies of
the supplemented or amended Prospectus provided for in Section 2.3(a)(i) hereof,
or until it is advised in writing by Buyer that the Prospectus may be used, and
has received copies of any additional or supplemental filings that are
incorporated or deemed incorporated by reference in such Prospectus.

          (c) In the event any of the events or circumstances listed in the
foregoing paragraph (b) occur or exist after a Selling Period has commenced,
subject to paragraph (d) below, Buyer shall have the same right to suspend such
Selling Period by delivery of a Suspension Notice as Buyer would have had if the
Selling Period had not yet commenced, and any such suspension of a Selling
Period shall be deemed included within the meaning of the term "Suspension" for
all purposes under this Agreement.

          (d) In the event of any Suspension, or any delay in effecting the
Shelf Registration under Section 2.2 above, Buyer will use its reasonable
efforts to ensure that the use of the Prospectus so suspended or delayed may be
commenced or resumed, as the case may be, and that any Selling Period so
suspended will commence or resume, as the case may be, as

                                      -22-

<PAGE>   6

soon as practicable and, in the case of a pending development, filing or event
referred to in Section 2.3(b)(iv) or (v) hereof, as soon, in the judgment of
Buyer's Board of Directors, as disclosure of the material relating to such
pending development, filing or event would not have an adverse effect on Buyer's
ability to consummate the transaction, if any, to which such development, filing
or event relates. Notwithstanding any other provision of this Agreement, Buyer
shall have the right to cause a maximum of two (2) Suspensions, neither of which
may be within 30 days of the other, as provided above (including for this
purpose a delay in effecting the Shelf Registration pursuant to Section 2.2
above) during any 12-month period after the initial effective date of the Shelf
Registration Statement, and the total number of days in any 12-month period
during which a Suspension or Suspensions (including for this purpose a delay in
effecting the Shelf Registration Statement pursuant to Section 2.2 above) may be
in effect shall not exceed 90 days.

          (e) Subject to the provisions of Section 2.2, Buyer will use its
reasonable efforts to maintain the effectiveness until November 30, 2000 of any
Registration Statement pursuant to which any of the Registrable Securities are
being offered. Buyer from time to time will amend or supplement such
Registration Statement and the Prospectus contained therein to the extent
necessary to comply with the 1933 Act and any applicable state securities
statute or regulation. Buyer will also provide each holder of Registrable
Securities with as many copies of the Prospectus contained in any such
Registration Statement as it may reasonably request.

     3.   RESTRICTIONS ON TRANSFER OF SHARES; RULE 144 AVAILABILITY

          (a) The Holders agree, understand and acknowledge that the issuance of
the Registrable Securities to the Holders has not been, and, except as
contemplated in this Agreement, the sale or other disposition thereof by the
Holders will not be, registered under the 1933 Act or the securities laws of any
state and that the transfer, sale, disposal or assignment of such shares is
subject to restriction as set forth in Section 6.10 and 6.11 of the Purchase
Agreement and will bear the legends set forth in those Sections. The Holders
acknowledge that, except as expressly set forth in this Agreement, the Holders
have no right to require Buyer to cause the registration of any Registrable
Securities.

          (b) With a view to making available to the Holders the benefits of
Rule 144 promulgated under the 1933 Act and Form S-3 and any other rule or
regulation of the Commission that may at any time after the Release Date permit
such Holder to sell securities of the Company to the public without
registration, the Company agrees to use its best efforts to:

          (i)  make and keep public information available, as those terms are
               understood and defined in Rule 144 under the 1933 Act;

                                      -23-

<PAGE>   7
           (ii) file with the Commission in a timely manner all reports and
                other documents required of the Company under the 1933 Act and
                the 1934 Act; and

          (iii) furnish to any holder of Registrable Shares upon request a

                written statement by the Company as to its compliance with the
                reporting requirements of said Rule 144 and of the 1933 Act and
                the 1934 Act, a copy of the most recent annual or quarterly
                report of the Company, and such other reports and documents of
                the Company as such holder may reasonably request to avail
                itself of any similar rule or regulation of the Commission
                allowing it to sell any such securities without registration.

     4.    EXPENSES

     Buyer will pay all Registration Expenses in connection with the
registration of Registrable Securities effected by Buyer pursuant to Section 2.
Holders of Registrable Securities registered pursuant to this Agreement shall
pay all Selling Expenses associated with such registration, with each Holder
bearing a pro rata portion of the Selling Expenses based upon the number of
Registrable Securities registered by each Holder.

     5.    EXPIRATION OF REGISTRATION RIGHTS

     The obligations of Buyer under Section 2 of this Agreement to register the
Registrable Securities shall expire and terminate at such time as the
Shareholders shall be entitled or eligible to sell all such securities in the
United States or to a U.S. person (as defined in Regulation S under the 1933
Act) without restriction and without a need for the filing of a registration
statement under the 1933 Act. The obligations of Buyer under Section 2 of this
Agreement shall expire on November 30, 2000 (provided no stop transfer orders
are in place with the transfer agent).

     6.    REGISTRATION PROCEDURES

     In connection with the registration of Registrable Securities under this
Agreement, and subject to the other provisions of this Agreement, Buyer shall:

          (a) use its reasonable efforts to cause the Registration Statement
filed in accordance with Section 2 to become effective as soon as practicable
after the Release Date;

          (b) prepare and file with the Commission such amendments and
supplements to such Registration Statement and the Prospectus used in connection
therewith as may be necessary to keep such Registration Statement continuously
effective for the shorter of (i) the duration of its registration obligations
pursuant to Section 2, or (ii) until there are no

                                      -24-

<PAGE>   8

Registrable Securities outstanding, and to comply with the provisions of the
1933 Act with respect to the disposition of the Registrable Securities;

          (c) furnish to each Seller of such Registrable Securities such number
of copies of the Prospectus included in such Registration Statement as such
Seller may reasonably request in order to facilitate the sale or disposition of
such Registrable Securities;

          (d) use its reasonable efforts to register or qualify all securities
covered by such Registration Statement under such other securities or "blue sky"
laws of such jurisdictions as each Seller shall reasonably request, and do any
and all other acts and things as may be reasonably necessary to enable such
Seller to consummate the disposition in such jurisdictions of its Registrable
Securities covered by such Registration Statement, except that Buyer shall not
for any such purpose be required to qualify generally to do business as a
foreign corporation in any jurisdiction wherein it is not so qualified, or to
subject itself to taxation in respect of doing business in any such
jurisdiction, or to consent to general service of process in any such
jurisdiction;

          (e) notify each Seller of Registrable Securities covered by such
Registration Statement, at any time when a Prospectus relating thereto is
required to be delivered under the 1933 Act, of the happening of any event as a
result of which the Prospectus included in such Registration Statement, as then
in effect, includes an untrue statement of a material fact or omits to state any
material fact required to be stated therein or necessary to make the statements
therein not misleading in light of the circumstances then existing or if it is
necessary to amend or supplement such Prospectus to comply with the law, and at
the request of any such Seller, prepare and furnish to such Seller a reasonable
number of copies of a supplement to or an amendment of such Prospectus as may be
necessary so that, as thereafter delivered to the purchasers of such Registrable
Securities or securities, such Prospectus, as amended or supplemented, will
comply with the law;

          (f) use its best efforts to comply with all applicable rules and
regulations of the Commission;

          (g) use its best efforts to qualify such securities for listing on the
Nasdaq National Market, and provide a transfer agent and registrar for such
Registrable Securities not later than the effective date of such Registration
Statement; and

          (h) issue to any person to which any Holder of Registrable Securities
may sell such Registrable Securities in connection with such registration
certificates evidencing such Registrable Securities without any legend
restricting the transferability of the Registrable Securities.

     Buyer will promptly amend or supplement such Registration Statement and the
Prospectus contained therein whenever and to the extent necessary to comply with
the 1933

                                      -25-

<PAGE>   9

Act and any applicable state securities statute or regulation. Buyer will also
provide the Holder of Registrable Securities with as many copies of the
Prospectus contained in any such Registration Statement as it may reasonably
request.

     7.    1934 ACT REGISTRATION

     Buyer shall timely file with the Commission such information as the
Commission may require under Section 13 or 15(d) of the 1934 Act; and in such
event, Buyer shall use its best efforts to take all action pursuant to Rule
144(c) as may be required as a condition to the availability of Rule 144 under
the 1933 Act (or any successor exemptive rule hereinafter in effect) with
respect to such Common Stock. Buyer shall furnish to any holder of Registrable
Securities forthwith upon request (i) a written statement by Buyer as to its
compliance with the reporting requirements of Rule 144(c), (ii) a copy of the
most recent annual or quarterly report of Buyer as filed with the Commission,
and (iii) such other publicly-filed reports and documents as a holder may
reasonably request in availing itself of any rule or regulation of the
Commission allowing a holder to sell any such Registrable Securities without
registration.

     8.    SHAREHOLDER INFORMATION

     It shall be a condition precedent to the obligations of Buyer to take any
action pursuant to this Agreement that all Holders shall furnish to Buyer such
information regarding themselves, the Registrable Securities held by them and
the intended method of disposition of such Registrable Securities as shall be
reasonably required to effect the registration of their Registrable Securities
and to execute such documents in connection with such registration as Buyer may
reasonably request. In addition, each Holder agrees to dispose of any
Registrable Securities included in any registration only in accordance with the
plan of distribution described in the Registration Statement.

     9.    INDEMNIFICATION AND CONTRIBUTION

     In the event any Registrable Securities are included in a Registration
Statement under this Agreement:

          (a) In the event of any registration of any Registrable Securities
under the 1933 Act pursuant to this Agreement, then to the extent permitted by
law, Buyer will indemnify and hold harmless each Seller and any of his agents,
and any underwriter (as defined in the 1933 Act) for such Seller and each
person, if any, who controls such Seller or underwriter within the meaning of
the 1933 Act or the 1934 Act, against any losses, claims, damages, liabilities
and expenses (including reasonable attorneys fees) (joint or several) to which
they may become subject under the 1933 Act, the 1934 Act or other federal or
state law, insofar as such losses, claims, damages, liabilities and expenses
(including reasonable attorneys fees (or actions in respect thereof) arise out
of or are based upon any of the following statements, omissions or violations
(the following are collectively referred to as a

                                      -26-

<PAGE>   10

"VIOLATION"): (i) any untrue statement or alleged untrue statement of a material
fact contained in such Registration Statement, including any preliminary
prospectus or final prospectus contained therein or any amendments or
supplements thereto; (ii) the omission or alleged omission to state therein a
material fact required to be stated therein, or necessary to make the statements
therein, in light of the circumstances under which they were made, not
misleading; or (iii) any violation or alleged violation by Buyer of the 1933
Act, the 1934 Act, any state securities law or any rule or regulation
promulgated under the 1933 Act, the 1934 Act or any state securities law; and
Buyer will reimburse each such Seller, his agent, underwriter or controlling
person for any reasonable legal or other expenses reasonably incurred by them in
connection with investigating or defending any such loss, claim, damage,
liability or action. Notwithstanding anything contained in this Agreement to the
contrary, the indemnity agreement contained in this Section 9 shall not apply to
amounts paid in settlement of any such loss, claim, damage, liability or action
if such settlement is effected without the consent of Buyer (which consent shall
not be unreasonably withheld, conditioned or delayed), nor shall Buyer be liable
in any such case for any such loss, claim, damage, liability or action to the
extent that it arises out of or is based upon a Violation which occurs in
reliance upon and in conformity with written information furnished to Buyer
expressly for use in connection with such registration by any such Seller,
underwriter or controlling person.

          (b) In the event of any registration of any Registrable Securities
under the 1933 Act pursuant to this Agreement, then to the extent permitted by
law, each Seller will indemnify and hold harmless Buyer, each of its officers,
directors, agents or employees, any underwriter (as defined in the 1933 Act) and
each person, if any, who controls Buyer or any underwriter for Buyer within the
meaning of the 1933 Act or the 1934 Act, and any other Seller or any of his
agents, underwriter or any person who controls such Seller within the meaning of
the 1933 Act or the 1934 Act, against any losses, claims, damages or liabilities
and expenses (including reasonable attorneys fees) (joint or several) to which
Buyer or any such director, officer, partner, agent, employee, controlling
person or underwriter, or other such Seller or agent, underwriter or controlling
person may become subject, under the 1933 Act, the 1934 Act or other federal or
state law, insofar as such losses, claims, damages, liabilities and expenses
(including reasonable attorneys fees) (or actions in respect thereto) arise out
of or are based upon any Violation, in each case to the extent (and only to the
extent) that such Violation occurs in reliance upon and in conformity with
written information furnished by such Seller expressly for use in connection
with such registration; and each such Seller will reimburse any reasonable legal
or other expenses reasonably incurred by Buyer or any such director, officer,
partner, agent, employee, controlling person or underwriter, other Seller,
agent, underwriter or controlling person in connection with investigating or
defending any such loss, claim, damage, liability or action. Notwithstanding
anything contained in this Agreement to the contrary, the indemnity agreement
contained in this Section 9(b) shall not apply to amounts paid in settlement of
any such loss, claim, damage, liability or action if such settlement is effected
without the consent of the Seller (which consent shall not be unreasonably
withheld, conditioned or delayed) provided further, that the aggregate liability
of each Seller in connection with any sale of Registrable Securities pursuant to
a Registration

                                      -27-

<PAGE>   11

Statement in which a Violation occurred shall be limited to the net proceeds
from such sale received by such Seller.

          (c) Promptly after receipt by an indemnified party under this Section
9 of notice of the commencement of any action (including any governmental
action), such indemnified party will, if a claim in respect thereof is to be
made against any indemnifying party under this Section 9, deliver to the
indemnifying party a written notice of the commencement thereof and the
indemnifying party shall have the right to participate in, and, to the extent
the indemnifying party so desires, jointly with any other indemnifying party
similarly noticed, to assume the defense thereof with counsel mutually
satisfactory to the parties; provided, however, that an indemnified party shall
have the right to retain its own counsel, with the fees and expenses to be paid
by the indemnifying party, if representation of such indemnified party by the
counsel retained by the indemnifying party would be inappropriate due to actual
or potential differing or conflicting interests between such indemnified party
and any other party represented by such counsel in such proceeding. The failure
to deliver written notice to the indemnifying party within a reasonable time of
the commencement of any such action, to the extent prejudicial to its ability to
defend such action, shall relieve such indemnifying party of liability to the
indemnified party under this Section 9 to the extent of such prejudice, but the
omission so to deliver written notice to the indemnifying party will not relieve
it of any liability that it may have to any indemnified party otherwise than
under this Section 9.

          (d) If recovery is not available under the foregoing indemnification
provisions of this Section 9, for any reason other than as specified therein,
the parties entitled to indemnification by the terms thereof shall be entitled
to contribution to liabilities and expenses in such proportion as is appropriate
to reflect the relative fault of the indemnifying parties and the indemnified
parties, except to the extent that contribution is not permitted under Section
11(f) of the 1933 Act. The relative fault of such indemnifying party and
indemnified party shall be determined by reference to, among other things, the
parties' relative knowledge and access to information concerning the matter with
respect to which the claim was asserted, the opportunity to correct and prevent
any statement or omission and any other equitable considerations appropriate
under the circumstances, including, without limitation, whether any untrue
statement or alleged untrue statement of a material fact or omission or alleged
omission to state a material fact relates to information supplied by Buyer, on
the one hand, or by the Seller, on the other hand. Buyer and the Seller of the
Registrable Securities covered by such Registration Statement agree that it
would not be equitable if the amount of such contribution were determined by pro
rata or per capita allocation. No Seller of Registrable Securities covered by
such Registration Statement or person controlling such Seller shall be obligated
to make any contribution hereunder which in the aggregate exceeds the net
proceeds from the Registrable Securities sold by such Seller, less the aggregate
amount of any damages which such Seller and its controlling persons have
otherwise been required to pay in respect of the same claim or any substantially
similar claim. The obligations of such Sellers to contribute are

                                      -28-

<PAGE>   12

several in proportion to their respective ownership of the Registrable
Securities covered by such Registration Statement and not joint.

     10.   NON-ASSIGNABILITY OF REGISTRATION RIGHTS

     The rights to cause Buyer, or its successors or assigns, to register
Registrable Securities pursuant to this Agreement are reserved solely for the
use and benefit of the Holders and may not be assigned or transferred by the
Holders to any other person; PROVIDED, HOWEVER, that any Holder who is a natural
person may transfer Registrable Securities to any member of the immediate family
of a Holder who is a natural person, or any trust or other fiduciary arrangement
for the benefit of such family member.

     11.   MISCELLANEOUS

     11.1  AMENDMENTS AND WAIVERS

     Any provision of this Agreement may be amended and the observance thereof
may only be waived (either generally or in a particular instance and either
retroactively or prospectively), with the written consent of Buyer and the
Holders of at least two thirds of the Registrable Securities then outstanding.
Any amendment or waiver effected in accordance with this Section shall be
binding upon each Holder of Registrable Securities at the time outstanding, each
future Holder of Registrable Securities, and Buyer.
