                                IntraLinks, Inc.

                           1997 STOCK INCENTIVE PLAN

1.    Purpose

      IntraLink's, Inc., (the "Company") plans to attract and retain the best
available talent and to encourage high levels of employee performance which
benefit the Company and its shareholders. The Company believes that the 1997
Stock Incentive Plan (the "1997 Plan") will contribute to the attainment of
these objectives. The 1997 Plan affords key personnel the opportunity to acquire
a proprietary equity interest in the Company and provides them with financial
incentives to put forth their maximum efforts for the success of the Company's
business.

2.    Scope and Duration

      Awards under the 1997 Plan may be granted:

      .     in the form of incentive stock options ("Incentive Options") as
            provided in Section 422 of the Internal Revenue Code of 1986, as
            amended (the "Code"), or

      .     in the form of nonqualified stock options ("Nonqualified Options"),
            or

      .     in the form of restricted shares ("Restricted Shares").

      References in the 1997 Plan to "Awards" include Restricted Shares,
Incentive Options and Nonqualified Options. "Options" include Incentive Options
and Nonqualified Options.

      "Outstanding Shares" means the total number of (a) IntraLinks' common
shares issued and outstanding, plus (b) common share equivalents on an
"as-converted" basis arising from IntraLinks' convertible preferred stock, plus
(c) common shares which may be acquired under vested and unvested Options,
warrants and other rights to acquire the Company's common shares, which are
outstanding as of January 1st of the given Plan year. Shares as to which Awards
may be granted may be, in whole or in part, authorized but unissued shares or
Treasury shares.

      The maximum aggregate number shares as to which Awards may be granted from
time to time to all recipients under the 1997 Plan will be as follows:

                        Year    Maximum Shares
                        ----    --------------
                        1997    30,000 Shares
                        1998    4% of the Outstanding Shares
                        1999    4% of the Outstanding Shares
                        2000    4% of the Outstanding Shares

      Restricted shares shall be no more than 10% of the total shares eligible
for Awards.

      The 1997 Plan shall terminate on December 31, 2000, unless terminated
sooner pursuant to paragraph 9 of this 1997 Plan. No Awards shall be granted
after that date.

3.    Administration

      The 1997 Plan shall be administered by the Compensation Committee of the
Company's Board of Directors (the "Committee"). If required, each member of the
Committee shall be a "disinterested person" as defined in Rule 16b-3 pursuant to
the Securities Exchange Act of 1934 or an "outside director", as that term is
used in Section 162(m) of the Code and the Treasury Regulations promulgated
thereunder.

      Subject to and consistent with the specific provisions of the 1997 Plan,
the Committee in its discretion shall have plenary authority to:

      .     determine the purchase price of the shares covered by each Option,
            the term of each Award, the persons to whom, and the time or times
            at which, Awards shall be granted, and the number of shares to be
            covered by each Award;

      .     designate shares as Incentive Options or Nonqualified Options or
            Restricted Stock;

      .     interpret the 1997 Plan;

      .     prescribe, amend, and rescind rules and regulations relating the
            1997 Plan;

      .     determine the terms and provisions of the Award agreements (which
            need not be identical) entered into in connection with Awards under
            the 1997 Plan;

      .     accelerate the exercise dates or vesting of all or any portion of an
            Award or to extend the period during which an Award may be
            exercised; and

      .     make all other determinations deemed necessary or advisable for the
            administration of the 1997 Plan.

      The Committee may delegate to one or more of its members, or to one or
more agents, such administrative duties as it may deem advisable. The Committee
(or any person to whom it has delegated duties) may employ one or more persons
to render advice about any responsibility the Committee or such person may have
under the 1997 Plan.

4.    Eligibility; Factors to be Considered in Granting Awards

      Incentive Options shall be limited to employees of the Company, including
officers and directors who are employees. Nonqualified Options and Restricted
Shares may be granted to employees of the Company, to non-employees of the
Company (including non-employee directors) and to independent agents and
consultants to the Company, in each case to persons whom the Committee believes
have contributed, or will contribute, to the success of the Company.

      In determining which employees shall be granted Awards, the Committee
shall take into account the nature and relative importance of employees' duties,
their present and potential contributions to the success of the Company,
achievement of business performance goals tied to annual operating plans, and
such other factors as it shall deem relevant in connection with accomplishing
the objectives of the 1997 Plan.

      (A) Options. The Committee may grant Options on the following terms and
conditions:

      1. Price of Options. The purchase price per share of shares covered by

subparagraph 5(B) below, in no event shall the Strike Price be less than 100% of
the Fair Market Value (as defined in paragraph 10 below) of a share on the date
on which the Option is granted. The Strike Price of any Option shall be subject
to adjustment from time to time as provided in paragraph 7 below. The Committee
shall determine the date on which Option shares are granted.

      2. Term of Options. Subject to subparagraph 5(B) below, the term of each
Option shall be not more than ten (10) years from the date of grant as the
Committee shall determine. Options may be subject to earlier termination in the
event of the Option Holder's termination of service, as provided by the
Committee.

      (B) Exercise of Options.

      1. The period during which any Option granted may be exercised shall be
determined in each case by the Committee.

      2. Options available for exercise may be exercised on any business day at
any time, or from time to time, as to any or all full shares to which the Option
applies.

      3. The purchase price of shares covered by each Option shall be paid in
full at the time of exercise. Payment may be made:

      .     in cash; or

      .     by delivery of a promissory note (which shall be due and payable in
            one year and bear interest no less than at the lowest applicable IRS
            rate and provided that such note is secured by the purchased
            shares); or

      .     by payment in shares of the Company which already are owned by the
            Option Holder, valued at the Fair Market Value (as defined in
            paragraph 10 below) on the date of exercise, subject to compliance
            with applicable laws, regulations and such other conditions as the
            Committee may impose in its sole discretion.

      4. Any amounts necessary to satisfy federal, state or local tax
withholding obligations of the Company or of the Option Holder shall be paid by
the Option Holder at time of the Option exercise.

      5. The Committee, either at the time of grant or thereafter, will
determine the period during which an Option may be exercised after an Option

5.    Specific Terms of Awards (Continued)

      (C) Substitution of Options.

      During the term of the 1997 Plan, the Committee in its discretion may
offer one or more Option Holders the opportunity to surrender any or all
unexpired options for cancellation or replacement. If any options are
surrendered, the Committee then may grant new Nonqualified or Incentive Options
to such Option Holder for the same or different numbers of options at a higher
or lower Strike Price than the surrendered options. Such new options may have a
different term than the surrendered options but shall otherwise be subject to
the provisions of the 1997 Plan.

      (D) Incentive Options.

      1. At the time Incentive Options are granted, the aggregate purchase price
of all Incentive Options (calculated by multiplying the number of shares covered
by such Incentive Options by the Strike Price) exercisable by an employee during
any calendar year shall not exceed $100,000 (as described and defined in Section
424 of the Code) unless the Code subsequently is amended to provide for a higher
annual limit.

      2. No Incentive Options may be awarded to any employee who, immediately
prior to the grant date of such Incentive Option, owns more than 10% of the
combined voting power of all classes of Outstanding Shares of the Company --
unless the Strike Price is at least 110% of the Fair Market Value and the Option
expires within five (5) years from the date of the grant.

      3. In the event of amendments to the Code or applicable regulations
relating to Incentive Options subsequent to the date of this 1997 Plan, the
Company may amend the provisions of the 1997 Plan. The Company and the employees
holding Options may agree to amend outstanding Options agreements to conform to
such amendments.

      (E) Restricted Shares. The Committee is authorized to grant Restricted
Shares to employees or other persons as provided in paragraph 4, on the
following terms and conditions:

      1. Issuance and Restrictions. Restricted Shares shall be subject to
restrictions on transferability as described in the Company's Shareholders'
Agreement, and may be subject to such other restrictions, if any, as the
Committee may impose at the date of grant or thereafter. Such restrictions may
lapse separately or in combination at such times, under such circumstances
(including, without limitation, upon achievement of performance criteria if
deemed appropriate by the Committee) and in such installments or otherwise as
the Committee may determine. Except to the extent restricted under the Award
agreement relating to the Restricted Shares, an employee granted Restricted
Shares shall have all of the rights of a shareholder including, without
limitation, the right to vote Restricted Shares and the right to receive
dividends.

      2. Forfeiture. Except as otherwise determined by the Committee at the date
of grant or thereafter, upon termination of employment during the applicable
restriction period, Restricted Shares and any accrued but unpaid dividends (that
are subject to restrictions) shall be forfeited. The Committee may provide, by
rule or regulation or in any Award agreement, or may determine in any individual
case, that restrictions or forfeiture conditions relating to such Restricted
Shares will be waived or modified in whole or in part in event of a termination
resulting from specified causes. The Committee may waive in whole or in part the
forfeiture of Restricted Shares.

5.    Specific Terms of Awards. (Paragraph 5(E), Continued)

      3. Certificates for Shares. Restricted Shares granted under the 1997 Plan
may be evidenced in such manner as the Committee shall determine. If
certificates representing Restricted Shares are registered in the name of the
employee, such certificates shall bear an appropriate legend referring to the
terms, conditions, and any restrictions applicable to such Restricted Shares.
The Company shall retain physical possession of the certificates.

      4. Distributions. Distributions, including dividends, paid on Restricted
Shares either shall be paid at the distribution payment date, or deferred for
payment to such date as determined by the Committee, paid in cash or paid in
unrestricted Shares having a Fair Market Value equal to the amount of such
distributions.

6.    Non-Transferability of Awards.

      Awards granted under the 1997 Plan shall not be transferable otherwise
than by will or the laws of descent and distribution. Options granted under the
1997 Plan may be exercised during the lifetime of the Option Holder only by the
Option Holder.

7.    Adjustments Upon Changes In Capitalization

      (A) Notwithstanding any other provisions of the 1997 Plan, the Committee
may at any time make or provide for such adjustments to the 1997 Plan, to the
number and class of shares issuable or to any outstanding awards as it shall
deem appropriate to prevent dilution or enlargement of rights. Adjustments may
be made in the event of changes in the Outstanding Shares by reason of share
distributions, split-ups, recapitalizations, mergers, consolidations,
combinations or exchanges of shares, separations, reorganizations, liquidations
and similar corporate transactions or events.

      (B) Any such adjustment to an Incentive Options shall be made in
accordance with Section 424(h) of the Code, unless the Committee determines
otherwise. In the event of any offer to holders of Outstanding Shares generally
relating to the acquisition of their shares, the Committee may make such
adjustment as it deems equitable in respect of outstanding Awards including, in
its discretion, revision of outstanding Awards so that they may be exercisable
for the consideration payable in the acquisition transaction. Any such
adjustment determination by the Committee shall be conclusive. Any fractional
shares resulting from such adjustments shall be eliminated.

      (C) Notwithstanding the above, Option Holders shall not have any
pre-emptive rights to maintain their proportionate equity ownership interest
(directly or on an "as-converted" basis) in the event that the Company issues
new primary shares to public or private investors.

8.    Effective Date.

      The 1997 Plan shall be effective as of June 30, 1997, subject to the
approval of the 1997 Plan by the Company's Shareholders within one year after
the effective date. Any grants of Awards prior to such approval shall be
effective when made (unless otherwise specified by the Committee at the time of
grant) but shall be conditioned upon, and subject to, approval of the 1997 Plan
by the Company's Shareholders (and no shares may be exercised prior to such
approval).

<PAGE>

--------------------------------------------------------------------------------

9.    Termination and Amendment

      The Company's Board may suspend, terminate or amend the 1997 Plan, subject
to the approval of the Company's Shareholders (if such approval is required by
law or by the Company's Shareholders' Agreement). Except as described in
paragraph 7, no suspension, termination or amendment of the 1997 Plan, without
the consent of the employee to whom an Award previously has been granted, may
adversely affect the rights of such employee under such previous Award.

10.   Miscellaneous.

      The term "Fair Market Value" (as used in the 1997 Plan) of the shares on
any day means:

      (A) if the principal market for the shares are a national securities
exchange or the NASDAQ National Market System, the closing sales price of the
shares on such day as reported by such exchange or market system, or

      (B) if the principal market for the shares is not a national securities
exchange or the NASDAQ National Market System, and the shares are quoted on the
National Association of Securities Dealers Automated Quotations System, the mean
between the closing bid and the closing asked prices for the shares on such day
as quoted on such System, or

      (C) if the principal market for the shares is not a national securities
exchange or the NASDAQ National Market System, and the shares are not quoted on
the National Association of Securities Dealers Automated Quotations System, the
mean between the highest bid and the lowest asked prices for the shares on such
day as reported by the National Quotation Bureau, Inc.

      If clauses (A), (B) and (C) of this paragraph all are inapplicable, or if
no trades have been made or no quotes are available for such day, or if the
Company shares are not publicly traded in any market, then the Fair Market Value
of the shares shall be determined by the Committee by any method which it deems
to be appropriate. If there has been a material arms-length private investment
in primary shares of common or convertible preferred stock of the Company within
six months prior to the date of the Award, then the Fair Market Value shall be
the price per share (adjusted for any splits, recapitalizations and the like)
paid in conjunction with such investment, unless the Committee shall determine
otherwise. The determination of the Committee shall be conclusive as to the Fair
Market Value of the shares.

      The Committee may require, as a condition to the issuance or delivery of
any shares granted under the 1997 Plan, to the extent required at the time of
exercise (i) that the shares reserved for purposes of the 1997 Plan shall be
duly listed, upon official notice of issuance, upon such share exchange(s) on
which the shares is listed, (ii) that a registration statement under the
Securities Act of 1933, with respect to such shares shall be effective, and/or
(iii) that the person receiving such shares deliver to the Company such
documents, agreements, investment representations and other representations as
the Committee shall determine to be in the best interests of the Company.

11.   No Right To Continued Employment.

      Nothing in the 1997 Plan or in any Awards granted pursuant to the 1997
Plan shall confer upon any employee any right to continue in the employ of the
Company.

      (d) Termination

            (i) Termination by Death. If the Optionee's employment by the

discretion.

            (iii) Termination For Cause. If the Optionee's employment by the
Company is terminated for Cause, his or her Option shall immediately terminate
and be of no further force and effect. All unexercised Option shares, whether

her Option, to the extent exercisable on the date of such termination of
employment, may be exercised during a specified period ("grace period") from the

      Length of Employment          Grace period
      --------------------          ------------
      Less than 1 year              none

            (v) Unvested Options. Whether by reason of death, Disability, for

      (e) Exercise of Option. In order to exercise the Option, the Optionee
shall submit to the Company an instrument in writing specifying the number of
Shares in respect of which the Option is being exercised, accompanied by payment
in a manner acceptable to the Company and consistent with the provisions of the
Plan, of the Option Price of the Shares in respect of which the Option is being
exercised. Shares shall then be issued by the Company and a share certificate
delivered to the Optionee; provided, however, that the Company shall not be
obligated to issue any Shares hereunder until all applicable securities laws and
other legal and stock exchange requirements have been satisfied, and the Company
shall not be obligated to issue any Share certificates hereinunder if another
method for recording share ownership is in effect under the Company's
Shareholders' Agreement.

      (f) No rights of Stockholder. The Optionee shall not, by virtue of the
Option, be entitled to any rights of a stockholder of the Company, either at law
or equity, and the grant of the Option shall not confer on the Optionee any
right with respect to continuance of his or her service with the Company nor
shall such grant interfere in any way with the right of the Company to terminate
the Optionee's service at any time.

      (g) Recapitalizations, Dividends and Adjustment. In the event of any
recapitalization, reclassification, split-up or consolidation of Shares,
separation (including a spin-off), dividend on Shares payable in capital stock
or other similar change in capitalization of the Company, merger or
consolidation of the Company, sale by the Company of all or a portion of its
assets or other similar event, the Compensation Committee of the Board (the
"Committee") shall make such appropriate adjustments in the exercise price of
the Option and in the number and kind of securities, cash or other property
which may be issued pursuant to the Option as the Committee deems equitable with
a view toward maintaining the proportionate interest of the Optionee and
preserving the value of the Option, all in accordance with paragraph 7. of the
1997 Plan.

      (h) Nontransferability. The Option shall not be transferable by the
Optionee except by will or the laws of decent and distribution, and it shall be
exercisable, during the Optionee's lifetime, only by the Optionee.

      (i) Withholding. The Optionee agrees to make appropriate arrangements with
the Company, consistent with the provisions of Section 9 of the 1997 Plan, for
satisfaction of any applicable tax withholding requirements, or similar
requirements, arising out of this Agreement.

      (j) References. References herein to rights and obligations of the
Optionee shall apply, where appropriate, to the Optionee's legal representative
or estate without regard to whether specific reference to such legal
representative or estate is contained in particular provision of this Agreement.
Capitalized terms referred to herein but not defined shall have the meanings
given to them in the 1997 Plan.

                           RESTRICTED STOCK AGREEMENT

      This Agreement is entered into as of _________, 199_, (the "Date of
Agreement") by and between IntraLinks, Inc. (the "Company") and ___________ (the
"Recipient").

      The Company has chosen the Recipient to participate in the 1997 Stock
Incentive Plan (the "1997 Plan") and to receive Restricted Stock of the Company.
In consideration of the premises and mutual covenants contained herein, and for
other good and valuable consideration, the Company and the Recipient agree as
follows:

      (a) Grant. Pursuant to the provisions of the 1997 Plan, the terms of which
are incorporated herein by reference, the Company hereby grants to the Recipient
an Award of ___________ Restricted Shares (the "Award") as of ________, 199_(the
"Date of Grant"). The Award will be held by the Company in a Restricted Stock
Account on behalf of the Recipient and will be credited annually with dividend
equivalents from the Date of Grant. This Grant is subject to the terms and
conditions of this Agreement, to the terms and conditions of the 1997 Plan, and
to the terms and conditions of the Company's Shareholders' Agreement.

      (b) Vesting. Except as otherwise provided in paragraph (f) below, the
Award shall fully vest and be 100% nonforfeitable, in accordance with the
following vesting schedule:

                                    This Award Shall Vest and Be Payable
                                    With Respect to the Following
                                    Cumulative Percentage of the
                                    Aggregate Number of Shares
      On or After This Date         Set Forth In Paragraph (a), Above:
      ---------------------         ----------------------------------
      1 Year from Date of Grant                 34%
      2 Years from Date of Grant                67%
      3 Years from Date of Grant               100%

      (c) Payment. Subject to the provisions of paragraph (e) below, as soon as
practicable after an Award has become vested in accordance with paragraph (b),
such vested Award, together with accumulated credits for dividend equivalents,
if any, shall be paid to the Recipient in unrestricted Common Shares of the
Company equal in number to the vested Award shares, subject to the continuing
restrictions, if any, on transferability set forth in paragraph (d) below. The
Compensation Committee of the Board (the "Committee") may, in its sole
discretion, provide that payment of vested Awards be deferred (a "Deferred
Award") until such time as the Recipient may elect. Any election of a Recipient
pursuant to the preceding sentence shall be filed in writing with the Committee
in accordance with such rules and regulations, including any deadline for the
making of such an election, as the Committee may provide from time to time.

--------------------------------------------------------------------------------

      (d) Issuance and Restrictions. Vested Awards shall be subject to
restrictions on transferability as described in the Company's Shareholders'
Agreement. Unvested Awards may be subject to other restrictions the Committee
may impose from time to time. Such restrictions may lapse separately or in
combination at such times, under such circumstances (including, without
limitation, upon achievement of performance criteria if deemed appropriate by
the Committee) in such installments or otherwise as the Committee may determine.
With respect to vested Awards, the Recipient shall have all of the rights of a
shareholder including, without limitation, the right to vote vested Restricted
Shares and the right to receive dividends.

      (e) Forfeiture. Except as otherwise determined by the Committee in its
sole discretion, upon termination of Recipient's employment during the
applicable vesting period for any reason whatsoever, including death,
disability, retirement, or termination of employment with or without cause,
unvested Awards and any accrued but unpaid dividends (that are subject to
vesting) shall be forfeited. The Committee may provide, by rule or regulation or
in any Award agreement, or may determine in any individual case, that
restrictions or forfeiture conditions relating to such unvested Awards will be
waived or modified in whole or in part in event of a termination resulting from
specified causes. The Committee may waive in whole or in part the forfeiture of
Awards.

      (f) Termination.

            (i) Termination by Death. If the Recipient's employment by the
Company terminates by reason of death or disability, any vested but unpaid
Deferred Award thereafter may be paid, to the extent it was payable as of the
date of death or disability, to the legal representative or legatee of the
Recipient in the case of death, or to the Recipient in the case of disability,
for a period of 12 months from the date of death or disability. For purposes of
this Agreement, the Recipient shall be deemed "Disabled" if he or she is unable
to perform services by reason of illness incapacity for a period of more than
two months, established by medical evidence satisfactory to the Committee in its
sole discretion.

            (ii) Termination For Cause. If the Recipient's employment by the
Company is terminated for Cause, his or her Deferred Award shall immediately
terminate and be of no further force and effect. All vested but unpaid Deferred
Award shares and all unvested Awards, then shall be forfeited and become null
and void. For purposes of this Agreement, "Cause" shall be deemed to mean one of
more of the following: (i) Recipient's embezzlement or misappropriation of
funds, (ii) Recipient's conviction of a felony involving moral turpitude, (iii)
Recipient's commission of material acts of dishonesty, fraud, or deceit, (iv)
Recipient's breach of any material provisions of any employment agreement with
the Company to which he or she is party, (v) Recipient's habitual or willful
neglect of his or her duties, (vi) Recipient's breach of fiduciary duty to the
Company involving personal profit, or (vii) Recipient's material violation of
any other duty to the Company or its stockholders imposed by law or by the Board
of Directors.

            (iii) Other Termination. If the Recipient's employment by the
Company is terminated for any reason other than death, Disability, or for Cause,
his or her Deferred Award, to the extent payable on the date of such termination
of employment, may be payable within 90 days from the date of termination of
employment, subject to paragraph (d) above.

--------------------------------------------------------------------------------

      (g) Certificates for Shares. Awards granted under this Agreement may be
evidenced in such manner as the Committee shall determine. If certificates
representing Restricted Shares are registered in the name of the employee, such
certificates shall bear an appropriate legend referring to the terms,
conditions, and any restrictions applicable to such Restricted Shares. The
Company shall retain physical possession of the certificates.

      (h) Non-Transferability of Awards. Awards granted under this Agreement
shall not be transferable otherwise than by will or the laws of descent and
distribution.

      (i) Adjustments Upon Changes In Capitalization

            (1) Notwithstanding any other provisions of this Agreement, the
Committee may at any time make or provide for such adjustments to the number and
class of shares issuable or to any outstanding Awards as it shall deem
appropriate to prevent dilution or enlargement of rights. Adjustments may be
made in the event of changes in the Outstanding Shares by reason of share
distributions, split-ups, recapitalizations, mergers, consolidations,
combinations or exchanges of shares, separations, reorganizations, liquidations
and other similar corporate transactions or events, all in accordance with
paragraph 7 of the 1997 Plan.

            (2) In the event of any offer to holders of Outstanding Shares
generally relating to the acquisition of their shares, the Committee may make
such adjustment as it deems equitable in respect of outstanding Awards
including, in its discretion, revision of outstanding Awards so that they may be
eligible for the consideration payable in the acquisition transaction. Any such
adjustment determination by the Committee shall be conclusive. Any fractional
shares resulting from such adjustments shall be eliminated.

            (3) Notwithstanding the above, the Recipient shall not have any
pre-emptive rights to maintain his or her proportionate equity ownership
interest in the Company (directly or on an "as-converted" basis) in the event
that the Company issues new primary shares to public or private investors.

      (j) No Rights of Stockholder. The Recipient shall not, by virtue of an
unvested Award, be entitled to any rights of a stockholder of the Company,
either at law or equity, and the Grant of the Award shall not confer on the
Recipient any right with respect to continuance of his or her service with the
Company nor shall such grant interfere in any way with the right of the Company
to terminate the Recipient's service at any time.

      (k) Withholding. The Recipient agrees to make appropriate arrangements
with the Company for satisfaction of any applicable tax withholding requirement,
or similar requirements, arising out of this Agreement.

      (l) References. References herein to rights and obligations of the
Recipient shall apply, where appropriate, to the Recipient's legal
representative or estate without regard to whether specific reference to such
legal representative or estate is contained in particular provision of this
Agreement. Capitalized terms not defined herein shall have the meanings given to
them in the 1997 Plan.

          2.  Required Registration.
              ---------------------

         (a)  At any time on or after the first anniversary of an initial public
offering of the Company, the Investors may request the Company to register under
the Securities Act all or any pro rata portion of the Restricted Stock held by
the Investors for sale in the manner specified in such notice; provided,
                                                               --------
however, that the only securities which the Company shall be required to
-------
register pursuant hereto shall be shares of Common Stock.
<PAGE>

          (b)  Promptly following receipt of any notice under this Section 2(a),
the Company shall immediately notify all holders of Restricted Stock and shall
use its best efforts to register under the Securities Act, for public sale in
accordance with the method of disposition specified in the notice from the
Investors, the number of shares of Restricted Stock specified in such notice
(and in any notices received from other holders of Restricted Stock within 20
days after their receipt of such notice from the Company); provided, however,
                                                           --------  -------
that if the proposed method of disposition specified by the Investors shall be
an underwritten public offering, the number of shares of Restricted Stock to be
included in such an offering will be reduced, pro rata (i) first among the
                                              --------
Original Stockholders and (ii) then, and only if Restricted Stock of Original
Stockholders is no longer to be included in such offering, among the Investors,
based on the number of shares of Restricted Stock so requested to be registered,
if and to the extent that the managing underwriter shall be of the opinion that
such inclusion would adversely affect the marketing of the Restricted Stock to
be sold.  If such method of disposition shall be an underwritten public
offering, the Company may designate the managing underwriter of such offering,
subject to the approval of the Investors, which approval shall not be
unreasonably withheld.  The Company shall be obligated to register Restricted
Stock pursuant to this Section 2 on one occasion only.

          (c)  The Company shall be entitled to include in any registration
statement referred to in this Section 2, for sale in accordance with the method
of disposition specified by the requesting holders, shares of Common Stock to be
sold by the Company for its own account, except as and to the extent that, in
the opinion of the managing underwriter (if such method of disposition shall be
an underwritten public offering), such inclusion would adversely affect the
marketing of the Investor Restricted Stock to be sold. Except as provided in
this paragraph (c), the Company will not effect any other registration of its
Common Stock, whether for its own account or that of other holders, from the
date of receipt of a notice from requesting holders pursuant to this Section 2
until the completion of the period of distribution of the registration
contemplated thereby.

          3.   Form S-3 Registration.
               ---------------------

          (a)  At the time that the Company is qualified to use a Form S-3 for
registration for shares of its own stock or for
<PAGE>

shares of its stockholders and if the Company shall receive from any holder or
holders of Restricted Stock a written request or requests that the Company
effect a registration on Form S-3 and any related qualification or compliance
with respect to Restricted Stock owned by such holder or holders, the Company
will:

          (i)  promptly give written notice of the proposed registration, and
     any related qualification or compliance, to all other holders of Restricted
     Stock; and

          (ii) as soon as practicable, effect such registration (including,
     without limitation, the execution of an undertaking to file post-effective
     amendments, appropriate qualifications under applicable blue sky or other
     state securities laws and appropriate compliance with applicable
     regulations issued under the Securities Act and any other government
     requirements or regulations) as may be so requested and as would permit or
     facilitate the sale and distribution of all or such portion of such
     holder's or holders' Restricted Stock as are specified in such request,
     together with all or such portion of the Restricted Stock of any holder or
     holders joining in such request as are specified in a written request given
     within thirty (30) days after receipt of such written notice from the
     Company, provided that the Company shall not be obligated to effect any
     such registration, qualification or compliance pursuant to this Agreement
     (A) more than once in any 270-day period, or (B) if the Company is not
     entitled to use Form S-3 for registration for shares of its own stock or
     for shares of its stockholders.  Subject to the foregoing, the Company
     shall file a registration statement covering the Restricted Stock so
     requested to be registered as soon as practicable after receipt of the
     request or requests of the holders of the Restricted Stock.

          (b)  Registrations effected pursuant to this Section 3 shall not be
counted as requests for registration effected pursuant to Section 2.

          (c)  Anything to the contrary in this Section 3 notwithstanding, a
registration shall not be effected pursuant to this Section 3 (i) for Restricted
Stock with an aggregate market value of less than $1,500,000, or (ii) once the
Restricted Stock otherwise may be sold to the public without restriction.
<PAGE>

          4.   Incidental Registration.  If the Company at any time (other than
               -----------------------
pursuant to Sections 2 and 3 hereof) proposes to register any of its Common
Stock under the Securities Act for sale to the public, whether for its own
account or for the account of other securityholders or both (except with respect
to registration statements on Form S-4 or S-8 or another form not available for
registering the Restricted Stock for sale to the public), it will give written
notice at such time to all holders of outstanding Restricted Stock of its
intention to do so.  Upon the written request of any such holder, given within
30 days after receipt of any such notice by the Company, to register any of its
Restricted Stock (which request shall state the intended method of disposition
thereof), the Company will use its best efforts to cause the Restricted Stock as
to which registration shall have been so requested to be included in the
securities to be covered by the registration statement proposed to be filed by
the Company, all to the extent requisite to permit the sale or other disposition
by the holder (in accordance with its written request) of such Restricted Stock
so registered; provided that nothing herein shall prevent the Company from
               --------
abandoning or delaying such registration at any time.  In the event that any
registration pursuant to this Section 4 shall be, in whole or in part, an
underwritten public offering of Common Stock, any request by a holder pursuant
to this Section 4 to register Restricted Stock shall specify that either (i)
such Restricted Stock is to be included in the underwriting on the same terms
and conditions as the shares of Common Stock otherwise being sold through
underwriters under such registration or (ii) such Restricted Stock is to be sold
in the open market without any underwriting, on terms and conditions comparable
to those normally applicable to offerings of common stock in reasonably similar
circumstances.  The number of shares of Restricted Stock to be included in such
an underwriting may be reduced (pro rata among the requesting holders of
                                --- ----
Restricted Stock based upon the number of shares of Restricted Stock so
requested to be registered) if and to the extent that the managing underwriter
shall be of the opinion that such inclusion would adversely affect the marketing
of the securities to be sold by the Company therein.

          Notwithstanding anything to the contrary contained in this Section 4,
in the event that there is a firm commitment underwritten public offering of
securities of the Company pursuant to a registration covering Restricted Stock
and a holder of Restricted Stock does not elect to sell his Restricted Stock to
the underwriters of the Company's securities in connection with
<PAGE>

such offering, such holder shall refrain from selling such Restricted Stock so
registered pursuant to this Section 4 during the period of distribution of the
Company's securities by such underwriters and the period of time in which the
underwriting syndicate participates in the after market; provided, however, that
                                                         --------  -------
such holder shall, in any event, be entitled to sell its Restricted Stock
commencing on the 180th day after the effective date of such registration
statement.

          5.  Registration Procedures and Expenses.  If and whenever the Company
              ------------------------------------
is required by the provisions of Sections 2, 3 and 4 hereof to use its best
efforts to effect the registration of any of the Restricted Stock under the
Securities Act, the Company will, as expeditiously as possible:

          (a) prepare (and afford counsel for the selling holders reasonable
     opportunity to review and comment thereon) and file with the Commission a
     registration statement (which, in the case of an underwritten public
     offering pursuant to Section 2 hereof, shall be on a form of general
     applicability satisfactory to the managing underwriter selected as therein
     provided) with respect to such securities and use its best efforts to cause
     such registration statement to become and remain effective for the period
     of the distribution contemplated thereby (determined as hereinafter
     provided);

          (b) prepare (and afford counsel for the selling holders reasonable
     opportunity to review and comment thereon)  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 effective for the period specified in paragraph (a)
     above and as comply with the provisions of the Securities Act with respect
     to the disposition of all Restricted Stock covered by such registration
     statement in accordance with the sellers' intended method of disposition
     set forth in such registration statement for such period;

          (c) furnish to each seller and to each underwriter such number of
     copies of the registration statement and the prospectus included therein
     (including each preliminary prospectus) as such persons may reasonably
     request in order to facilitate the public sale or other disposition of the
     Restricted Stock covered by such registration statement;
<PAGE>

          (d) use its best efforts to register or qualify the Restricted Stock
     covered by such registration statement under the securities or blue sky
     laws of such jurisdictions as the sellers of Restricted Stock or, in the
     case of an underwritten public offering, the managing underwriter, shall
     reasonably request (provided that the Company will not be required to (i)
     qualify generally to do business in any jurisdiction where it would not
     otherwise be required to qualify but for this paragraph (d), (ii) subject
     itself to taxation in any such jurisdiction or (iii) consent to general
     service of process in any jurisdiction);

          (e) immediately notify each seller under such registration statement
     and each underwriter, at any time when a prospectus relating thereto is
     required to be delivered under the Securities Act, of the happening of any
     event as a result of which the prospectus contained 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 the light of the
     circumstances then existing;

          (f) use its best efforts (if the offering is under-written) to
     furnish, at the request of any underwriter, on the date that Restricted
     Stock is delivered to the underwriters for sale pursuant to such
     registration:  (i) an opinion dated such date of counsel representing the
     Company for the purposes of such registration, addressed to the
     underwriters, stating that such registration statement has become effective
     under the Securities Act and that (A) to the best knowledge of such
     counsel, no stop order suspending the effectiveness thereof has been issued
     and no proceedings for that purpose have been instituted or are pending or
     contemplated under the Securities Act, (B) the registration statement, the
     related prospectus, and each amendment or supplement thereof, comply as to
     form in all material respects with the requirements of the Securities Act
     and the applicable rules and regulations of the Commission thereunder
     (except that such counsel need express no opinion as to financial
     statements, the notes thereto, and the financial schedules and other
     financial and statistical data contained therein) and (C) to such other
     effects as may reasonably be requested by counsel for the underwriters or
<PAGE>

     by such seller or its counsel, and (ii) a letter dated such date from the
     independent public accountants retained by the Company, addressed to the
     underwriters, stating that they are independent public accountants within
     the meaning of the Securities Act and that, in the opinion of such
     accountants, the financial statements of the Company included in the
     registration statement or the prospectus, or any amendment or supplement
     thereof, comply as to form in all material respects with the applicable
     accounting requirements of the Securities Act, and such letter shall
     additionally cover such other financial matters (including information as
     to the period ending no more than five business days prior to the date of
     such letter) with respect to the registration in respect of which such
     letter is being given as such underwriters or seller may reasonably
     request; and

          (g) during normal business hours and with reasonable notice, make
     available for inspection by each seller, any underwriter participating in
     any distribution pursuant to such registration statement, and any attorney,
     accountant or other agent retained by such seller or underwriter, all
     financial and other records, pertinent corporate documents and properties
     of the Company, and cause the Company's officers, directors and employees
     to supply all information reasonably requested by any such seller,
     underwriter, attorney, accountant or agent in connection with such
     registration statement and permit such seller, attorney, accountant or
     agent to participate in the preparation of such registration statement.

For purposes of paragraphs (a) and (b) above and of Section 2(c) hereof, the
period of distribution of Restricted Stock in a firm commitment underwritten
public offering shall be deemed to extend until each underwriter has completed
the distribution of all securities purchased by it, and the period of
distribution of Restricted Stock in any other registration shall be deemed to
extend until the earlier of the sale of all Restricted Stock covered thereby or
six months after the effective date thereof.

          In connection with each registration hereunder, the selling holders of
Restricted Stock will furnish to the Company in writing such information with
respect to themselves and the proposed distribution by them as shall be
reasonably necessary in order to assure compliance with federal and applicable
state securities laws.
<PAGE>

          In connection with each registration pursuant to Sections 2, 3 and 4
hereof covering an underwritten public offering, the Company agrees to enter
into a written agreement with the managing underwriter selected in the manner
herein provided in such form and containing such provisions as are customary in
the securities business for such an arrangement between major underwriters and
companies of the Company's size and investment stature, provided, however, that
                                                        --------  -------
such agreement shall not contain any such provision applicable to the Company
which is inconsistent with the provisions hereof and provided, further, however,
                                                     --------  -------  -------
that the time and place of the closing under said agreement shall be as mutually
agreed upon among the Company and such managing underwriter.

          6.  Expenses.  All expenses incurred by the Company in complying with
              --------
Sections 2, 3 and 4 hereof, including, without limitation, all registration and
filing fees, printing expenses, fees and disbursements of counsel and
independent public accountants for the Company, fees of the National Association
of Securities Dealers, Inc., transfer taxes, fees of transfer agents and
registrars and fees, but excluding any Selling Expenses and expenses of counsel
for the sellers of Restricted Stock, are herein called "Registration Expenses".
All underwriting discounts and selling commissions applicable to the sale of
Restricted Stock are herein called "Selling Expenses".

          The Company will pay all Registration Expenses in connection with each
registration statement filed pursuant to Sections 2, 3 and 4 hereof.

          7.  Indemnification.  In the event of a registration of any of the
              ---------------
Restricted Stock under the Securities Act pursuant to Sections 2, 3 or 4 hereof,
the Company will indemnify and hold harmless each seller of such Restricted
Stock thereunder and each underwriter of Restricted Stock thereunder and each
other person, if any, who controls such seller or underwriter within the meaning
of the Securities Act, against any losses, claims, damages or liabilities, joint
or several, to which such seller or underwriter or controlling person may become
subject under the Securities Act or otherwise, insofar as such losses, claims,
damages or liabilities (or actions in respect thereof) arise out of or are based
upon any untrue statement or alleged untrue statement of any material fact
contained in any registration statement under which such Restricted Stock was
registered under
<PAGE>

the Securities Act pursuant to Sections 2, 3 or 4, any preliminary prospectus or
final prospectus contained therein, or any amendment or supplement thereof, or
arise out of or are based upon the omission or alleged omission to state therein
a material fact required to be stated therein or necessary to make the
statements therein not misleading, and will reimburse each such seller, each
such underwriter and each such controlling person for any legal or other
expenses reasonably incurred by them in connection with investigating or
defending any such loss, claim, damage, liability or action; provided, however,
                                                             --------  -------
that the Company will not be liable in any such case if and to the extent that
any such loss, claim, damage or liability arises out of or is based upon an
untrue statement or alleged untrue statement or omission or alleged omission so
made in conformity with information furnished by such seller, such underwriter
or such controlling person in writing specifically for use in such registration
statement or prospectus.

          In the event of a registration of any of the Restricted Stock under
the Securities Act pursuant to Sections 2, 3 or 4 hereof, each seller of such
Restricted Stock thereunder, severally and not jointly, will indemnify and hold
harmless the Company and each person, if any, who controls the Company within
the meaning of the Securities Act, each officer of the Company who signs the
registration statement, each director of the Company, each underwriter and each
person who controls any underwriter within the meaning of the Securities Act,
against all losses, claims, damages or liabilities, joint or several, to which
the Company or such officer or director or underwriter or controlling person may
become subject under the Securities Act or otherwise, insofar as such losses,
claims, damages or liabilities (or actions in respect thereof) arise out of or
are based upon any untrue statement or alleged untrue statement of any material
fact contained in the registration statement under which such Restricted Stock
was registered under the Securities Act pursuant to Sections 2, 3 or 4, any
preliminary prospectus or final prospectus contained therein, or any amendment
or supplement thereof, or arise out of or are based upon the omission or alleged
omission to state therein a material fact required to be stated therein or
necessary to make the statements therein not misleading, and will reimburse the
Company and each such officer, director, underwriter and controlling person for
any legal or other expenses reasonably incurred by them in connection with
investigating or defending any such loss, claim, damage, liability or action;
provided, however, that such seller will be liable
--------  -------
<PAGE>

hereunder in any such case if and only to the extent that any such loss, claim,
damage or liability arises out of or is based upon an untrue statement or
alleged untrue statement or omission or alleged omission made in reliance upon
and in conformity with information pertaining to such seller, as such, furnished
in writing to the Company by such seller specifically for use in such
registration statement or prospectus; provided, further, however, that the
                                      --------  -------  -------
liability of each seller hereunder shall be limited to the proportion of any
such loss, claim, damage, liability or expense which is equal to the proportion
that the public offering price of shares sold by such seller under such
registration statement bears to the total public offering price of all
securities sold thereunder, but not to exceed the proceeds (net of underwriting
discounts and commissions) received by such seller from the sale of Restricted
Stock covered by such registration statement.

          Promptly after receipt by an indemnified party hereunder of notice of
the commencement of any action, such indemnified party shall, if a claim in
respect thereof is to be made against the indemnifying party hereunder, notify
the indemnifying party in writing thereof, but the omission so to notify the
indemnifying party shall not relieve it from any liability which it may have to
any indemnified party other than under this Section 8.  In case any such action
shall be brought against any indemnified party and it shall notify the
indemnifying party of the commencement thereof, the indemnifying party shall be
entitled to participate in and, to the extent it shall wish, to assume and
undertake the defense thereof with counsel satisfactory to such indemnified
party, and, after notice from the indemnifying party to such indemnified party
of its election so to assume and undertake the defense thereof, the indemnifying
party shall not be liable to such indemnified party under this Section 8 for any
legal expenses subsequently incurred by such indemnified party in connection
with the defense thereof other than reasonable costs of investigation and of
liaison with counsel so selected; provided, however, that, if the defendants in
                                  --------  -------
any such action include both the indemnified party and the indemnifying party
and the indemnified party shall have reasonably concluded that there may be
reasonable defenses available to it which are different from or additional to
those available to the indemnifying party, or if the interests of the
indemnified party reasonably may be deemed to conflict with the interests of the
indemnifying party, the indemnified party shall have the right to select a
separate counsel and to assume such legal defenses and
<PAGE>

otherwise to participate in the defense of such action, with the expenses and
fees of such separate counsel and other expenses related to such participation
to be reimbursed by the indemnifying party as incurred.

          Notwithstanding the foregoing, any indemnified party shall have the
right to retain its own counsel in any such action, but the fees and
disbursements of such counsel shall be at the expense of such indemnified party
unless (i) the indemnifying party shall have failed to retain counsel for the
indemnified person as aforesaid or (ii) the indemnifying party and such
indemnified party shall have mutually agreed to the retention of such counsel.
It is understood that the indemnifying party shall not, in connection with any
action or related actions in the same jurisdiction, be liable for the fees and
disbursements of more than one separate firm qualified in such jurisdiction to
act as counsel for the indemnified party.  The indemnifying party shall not be
liable for any settlement of any proceeding effected without its written
consent, but if settled with such consent or if there be a final judgment for
the plaintiff, the indemnifying party agrees to indemnify the indemnified party
from and against any loss or liability by reason of such settlement or judgment.

          If the indemnification provided for in the first two paragraphs of
this Section 7 is unavailable or insufficient to hold harmless an indemnified
party under such paragraphs in respect of any losses, claims, damages or
liabilities or actions in respect thereof referred to therein, then each
indemnifying party shall in lieu of indemnifying such indemnified party
contribute to the amount paid or payable by such indemnified party as a result
of such losses, claims, damages, liabilities or actions in such proportion as
appropriate to reflect the relative fault of the Company, on the one hand, and
the underwriters and the sellers of such Restricted Stock, on the other, in
connection with the statements or omissions which resulted in such losses,
claims, damages, liabilities or actions as well as any other relevant equitable
considerations, including the failure to give any notice under the third
paragraph of this Section 7.  The relative fault shall be determined by
reference to, among other things, whether the untrue or alleged untrue statement
of a material fact relates to information supplied by the Company, on the one
hand, or the underwriters and the sellers of such Restricted Stock, on the
other, and to the parties' relative intent, knowledge, access to information and
opportunity to correct or prevent such statement or omission.  The Company and
<PAGE>

each of you agree that it would not be just and equitable if contributions
pursuant to this paragraph were determined by pro rata allocation (even if all
                                              --- ----
of the sellers of such Restricted Stock were treated as one entity for such
purpose) or by any other method of allocation which did not take account of the
equitable considerations referred to above in this paragraph.  The amount paid
or payable by an indemnified party as a result of the losses, claims, damages,
liabilities or action in respect thereof, referred to above in this paragraph,
shall be deemed to include any legal or other expenses reasonably incurred by
such indemnified party in connection with investigating or defending any such
action or claim.  Notwithstanding the provisions of this paragraph, the sellers
of such Restricted Stock shall not be required to contribute any amount in
excess of the amount, if any, by which the total price at which the Common Stock
sold by each of them was offered to the public exceeds the amount of any damages
which they would have otherwise been required to pay by reason of such untrue or
alleged untrue statement or omission.  No person guilty of fraudulent
misrepresentations (within the meaning of Section 11(f) of the Securities Act),
shall be entitled to contribution from any person who is not guilty of such
fraudulent misrepresentation.

          The indemnification of underwriters provided for in this Section 7
shall be on such other terms and conditions as are at the time customary and
reasonably required by such underwriters.  In that event the indemnification of
the sellers of Restricted Stock in such underwriting shall at the sellers'
request be modified to conform to such terms and conditions.

          8.  Changes in Common Stock.  If, and as often as, there are any
              -----------------------
changes in the Common Stock by way of stock split, stock dividend, combination
or reclassification, or through merger, consolidation, reorganization or
recapitalization, or by any other means, appropriate adjustment shall be made in
the provisions hereof, as may be required, so that the rights and privileges
granted hereby shall continue with respect to the Common Stock as so changed.

          9.  Representations and Warranties of the Company.  The Company
              ---------------------------------------------
represents and warrants to you as follows:

          (a) The execution, delivery and performance of this Agreement by the
     Company have been duly authorized by all requisite corporate action and
     will not violate any provis-
<PAGE>

     ion of law, any order of any court or other agency of government, the
     Certificate of Incorporation or By-laws of the Company, or any provision of
     any indenture, agreement or other instrument to which it or any of its
     properties or assets is bound, or conflict with, result in a breach of or
     constitute (with due notice or lapse of time or both) a default under any
     such indenture, agreement or other instrument, or result in the creation or
     imposition of any lien, charge or encumbrance of any nature whatsoever upon
     any of the properties or assets of the Company.

          (b)  This Agreement has been duly executed and delivered by the
     Company and constitutes the legal, valid and binding obligation of the
     Company, enforceable in accordance with its terms, subject to
     considerations of public policy in the case of the indemnification
     provisions hereof.

          10.  Rule 144 Reporting.  The Company agrees with you as follows:
               ------------------

          (a)  The Company shall make and keep public information available, as
     those terms are understood and defined in Rule 144 under the Securities
     Act, at all times from and after the date it is first required to do so.

          (b)  The Company shall file with the Commission in a timely manner all
     reports and other documents as the Commission may prescribe under Section
     13(a) or 15(d) of the Exchange Act at any time after the Company has become
     subject to such reporting requirements of the Exchange Act.

          (c)  The Company shall furnish to such holder of Restricted Stock
     forthwith upon request (i) a written statement by the Company as to its
     compliance with the reporting requirements of Rule 144 (at any time from
     and after the date it first becomes subject to such reporting require-
     ments, and of the Securities Act and the Exchange Act (at any time after it
     has become subject to such reporting requirements), (ii) a copy of the most
     recent annual or quarterly report of the Company, and (iii) such other
     reports and documents so filed as a holder may reasonably request to avail
     itself of any rule or regulation of the Commission allowing a holder of
     Restricted Stock to sell any such securities without registration.
<PAGE>

          11.  Miscellaneous.
               -------------

          (a)  All covenants and agreements contained in this Agreement by or on
     behalf of any of the parties hereto shall bind and inure to the benefit of
     the respective successors and assigns of the parties hereto whether so
     expressed or not.  Without limiting the generality of the foregoing, the
     registration rights conferred herein on the holders of Restricted Stock
     shall inure to the benefit of any and all subsequent holders from time to
     time of the Restricted Stock.

          (b)  All notices, requests, consents and other communications

     or its address listed in the Company's records;

          if to any subsequent holder of Restricted Stock, to it at such address
     as may have been furnished to the Company in writing by such holder;

     or, in any case, at such other address or addresses as shall have been
     furnished in writing to the Company (in the case of a holder of Restricted
     Stock) or to the holders of Restricted Stock (in the case of the Company).

          (c)  This Agreement shall be governed by and construed in accordance
     with the laws of the State of Delaware, without giving effect to the
     principles of conflict of laws thereof.

          (d)  This Agreement constitutes the entire agreement of the parties
     with respect to the subject matter hereof and may not be modified or
     amended except in writing signed by the Company and (i) the holders of not
     less than a majority in interest of the holders of Restricted Stock then
     outstanding and (ii) a majority in interest of the holders of Series B
     Preferred Stock; provided that any such amendment
<PAGE>

     does not adversely effect the rights of any of the holders of Series B
     Preferred Stock.

          (e)  This Agreement may be executed in two or more counterparts, each
     of which shall be deemed an original, but all of which together shall
