applicable law, be within its absolute discretion (except as otherwise specifically provided herein) and shall be
conclusive and binding upon all Eligible Directors and any person claiming under or through any Eligible Director.

         Subject to the terms of the Plan and applicable law, and in addition to other express powers and
authorizations conferred on the Board of Directors by the Plan, the Board of Directors shall have full power and
authority to: (i) determine the number of Shares to be covered by, or with respect to which payments, rights, or

of any Option; (iii) interpret and administer the Plan and any instrument or agreement relating to, or Grant made

SECTION 4. SHARES AUTHORIZED FOR ISSUANCE.

         4.1
Maximum Number of Shares. The aggregate number of Shares with respect to which Grants may be
awarded to Eligible Directors under the Plan shall not exceed 250,000 Shares, subject to adjustment as provided in
Section 4.2 below, plus that number of Shares equal to the aggregate number of Shares credited to each Eligible
Director’s Stock Unit Account as a result of transfers of stock units from the Prior Plan pursuant to Section
9.10. If any Unit or Option is settled in cash or is forfeited without a distribution of Shares, the Shares
otherwise subject to such Unit or Option shall again be available for Grants hereunder.

         4.2 Adjustment for Corporate Transactions. In the event that any stock dividend, extraordinary cash
dividend, recapitalization, reorganization, merger, consolidation, split-up, spin-off, combination, exchange of
shares, warrants or rights offering to purchase Stock at a price substantially below Fair Market Value, or other
similar event affects the Stock such that an adjustment is required to preserve, or to prevent enlargement of, the
benefits or potential benefits made available under the Plan, then the Board of Directors shall adjust the number
and kind of shares which thereafter may be awarded under the Plan and the number of Units and Options and the
exercise price thereof that have been, or may be, granted under the Plan. Additionally, the Board of Directors
may make provisions for a cash payment to an Eligible Director.

SECTION 5. UNIT GRANTS.

         5.1 Unit Awards. Each Eligible Director (other than any Eligible Director who has received an award
under the Prior Plan) who is first elected or appointed to the Board of Directors

3

 

on or after the Effective Date of the Plan shall be awarded 1,500 Units on such date (or such other number of
Units as the Board shall determine). In addition, on the date of each Annual Meeting of Shareholders of the
Company occurring after 2000 and during the term of the Plan an eligible Director serving as a Director on such
date shall be awarded 350 Units (or such other number of Units as the Board shall determine).

         5.2 Delivery of Shares. Subject to satisfaction of the applicable vesting requirements set forth in
Section 6 and except as otherwise provided in Section 8, all Shares that are subject to any Units shall be
delivered to an Eligible Director and transferred on the books of the Company on the date which is the first
business day of the month immediately following the termination of such Eligible Director’s service as a
Director. Notwithstanding the foregoing, an Eligible Director may elect that all or a portion of his or her Units
shall be payable in cash as soon as practicable following the first business day of the month immediately
following the termination of such Eligible Director’s service as a Director. Any fractional Shares to be
delivered in respect of Units shall be settled in cash based upon the Fair Market Value on the date any whole
Shares are transferred on the books of the Company to the Eligible Director or the Eligible Director’s
beneficiary. The amount of any cash payment shall be determined by multiplying the number of Units and the number
of Units subject to a cash payment election by the Fair Market Value on the last business day preceding the
payment date. Upon the delivery of a Share (or cash with respect to a whole or fractional Share) pursuant to the
Plan, the corresponding Unit (or fraction thereof) shall be canceled and be of no further force or effect.

         5.3 Dividend Equivalents. An Eligible Director shall have no rights as a shareholder of the Company
with respect to any Units until Shares are delivered to the Director pursuant to this Section 5 hereof; provided
that, each Eligible Director shall have the right to receive an amount equal to the dividend per Share for the
applicable dividend payment date (which, in the case of any dividend distributable in property other than Shares,
shall be the per Share value of such dividend, as determined by the Company for purposes of income tax reporting)
times the number of Units held by such Eligible Director on the record date for the payment of such dividend (a
“Dividend Equivalent”). Each Eligible Director may elect, prior to any calendar year, whether the Dividend
Equivalent is (i) payable in cash, on or as soon as practicable after each date on which dividends are paid to
shareholders with respect to Shares; (ii) treated as reinvested in an additional number of Units determined by
dividing (A) the cash amount of any such dividend by (B) the Fair Market Value on the related dividend payment
date; or (iii) deferred and credited to the Eligible Director’s Interest Account pursuant to Section 9.4.

SECTION 6. UNIT VESTING.

         6.1 Service Requirements. Except as otherwise provided in this Section 6 or Section 8, an Eligible
Director shall vest in his or her Units as provided in this Section 6.1. If an Eligible Director terminates
service prior to the completion of three Years of Service as a Director, the number of Shares to be delivered to
such Eligible Director in respect of Units granted upon his or her election to the Board shall equal the amount
obtained by multiplying 1,500 by a fraction, the numerator of which is the number of full months of service
completed by such Director from the applicable date of Unit grant and the denominator of which is 36. If an
Eligible Director terminates service prior to the completion of one Year of Service as a Director from the date of
Unit grant with respect to any annual grant of Units made hereunder, the number of Shares to be delivered to such
Eligible Director in respect of such Unit grant shall equal the amount obtained by multiplying 350 by a fraction,
the numerator of which is the number of full months of service completed by such Director from the applicable date
of Unit grant and the denominator of which is 12. Notwithstanding the foregoing, and except as provided in
Section 6.2, if the Eligible Director terminates service by reason of his/her death, Disability, Retirement, or
acceptance of a position in Government Service prior to the completion of the period of service required to be
performed to fully vest in any Unit grant, all Shares that are the subject of such Unit grant (or, if elected by
the Eligible Director, the value thereof in cash) shall be delivered to such Eligible Director (or the Eligible
Director’s beneficiary or estate).

4

 

         6.2 Six Months’ Minimum Service. If an Eligible Director has completed less than six consecutive
months of service as a Director, all Units held by such Eligible Director shall be immediately forfeited. If an
Eligible Director has completed less than six consecutive months of service from any date on which any annual
grant of Units is made, all Units held by such Eligible Director that relate to such annual grant of units shall
be immediately forfeited.

         6.3 Distribution on Death. Except as provided in Section 6.2, in the event of the death of an
Eligible Director, the Shares corresponding to such Units or, at the election of the Eligible Director’s
beneficiary or estate, the Fair Market Value thereof in cash shall be delivered to the beneficiary designated by
the Eligible Director on a form provided by the Company, or, in the absence of such designation, to the Eligible
Director’s estate.

SECTION 7. STOCK OPTIONS.

         (a) 
Grant. Subject to the provisions of the Plan, the Board of Directors shall have the authority to
award Options to an Eligible Director and to determine (i) the number of Shares to be covered by each Option, (ii)
subject to Section 7(b), the exercise price of the Option and (iii) the conditions and limitations applicable to
the exercise of the Option.

         (b)  Exercise Price. The exercise price of an Option shall not be less than 100% of the Fair Market
Value on the date of grant.

         (c)  Exercise. Each Option shall be exercised at such times and subject to such terms and conditions as
the Board of Directors may specify at the time of the award of such Option or thereafter. No shares shall be
delivered pursuant to any exercise of an Option unless arrangements satisfactory to the Board of Directors have
been made to assure full payment of the exercise price therefor. Without limiting the generality of the foregoing,
payment of the exercise price may be made in cash or its equivalent or, if and to the extent permitted by the
Board of Directors by exchanging Shares owned by the Eligible Director (which are not the subject of any pledge or
other security interest) either actually or by attestation, or by a combination of the foregoing, provided that
the combined value of all cash and cash equivalents and the Fair Market Value of any such Shares so tendered to
the Company, valued as of the date of such tender, is at least equal to such exercise price.

         (d)  No Eligible Director shall have any rights as a shareholder with respect to any Shares to be issued
pursuant to any Option under the Plan prior to the issuance thereof.

SECTION 8. CHANGE IN CONTROL.

         8.1 Immediate Vesting. Upon the occurrence of a Change in Control, each Eligible Director’s right
and interest in Units and Options which have not previously vested shall become vested and nonforfeitable.

         8.2 Cash Settlement. (a) (i) Upon the occurrence of a Change in Control, in lieu of delivering
Shares with respect to the Units then held by an Eligible Director, the Company shall pay such Eligible Director,
not later than 60 days after the Change in Control occurs, cash in an aggregate amount equal to the product of (x)
the number of Shares that are subject to all Units credited to such Eligible Director at the time of the Change in
Control multiplied by (y) the Fair Market Value on the date of the Change in Control.

         (ii) Upon the occurrence of a Change in Control, the Company shall pay to each Eligible Director cash
in an amount equal to the accrued value of such Eligible Director’s Interest Account.

5

 

         (b)  Upon the occurrence of a Change in Control, in lieu of delivering Shares with respect to each
Option then held by an Eligible Director, the Company shall pay such Eligible Director, not later than 60 days
after the Change in Control occurs, cash in an aggregate amount equal to the product of (i) the number of Shares
that are subject to each Option held by such Eligible Director at the time of the Change in Control multiplied by
(ii) the amount by which the Fair Market Value on the date of the Change of Control exceeds the exercise price of
such Option.

         8.3 Definition. “Change in Control” shall mean the occurrence of any of the following events:

         (i)  When any “person” as defined in Section 3(a)(9) of the Exchange Act and as used in Sections
13(d) and 14(d) thereof, including a “group” as defined in Section 13(d) of the Exchange Act but excluding the
Company and any Subsidiary thereof and any employee benefit plan sponsored or maintained by the Company or any
Subsidiary (including any trustee of such plan acting as trustee), directly or indirectly, becomes the “beneficial
owner” (as defined in Rule 13d-3 under the Exchange Act, as amended from time to time), of securities of the
Company representing 20 percent or more of the combined voting power of the Company’s then outstanding securities;

         (ii)  When, during any period of 24 consecutive months the individuals who, at the beginning of such
period, constitute the Board (the “Incumbent Directors”) cease for any reason other than death to constitute at
least a majority thereof, provided that a Director who was not a Director at the beginning of such 24-month period
shall be deemed to have satisfied such 24-month requirement (and be an Incumbent Director) if such Director was
elected by, or on the recommendation of or with the approval of, at least two-thirds of the Directors who then
qualified as Incumbent Directors either actually (because they were directors at the beginning of such 24-month
period) or by prior operation of this Paragraph (ii); or

         (iii)  The occurrence of a transaction requiring stockholder approval for the acquisition of the
Company by an entity other than the Company or a Subsidiary through purchase of assets, or by merger, or otherwise.

         Notwithstanding the foregoing, in no event shall a Change in Control be deemed to have occurred
(i) as a result of the formation of a Holding Company, or (ii) with respect to a Director if the Director
is part of a “group”, within the meaning of Section 13(a)(3) of the Exchange Act as in effect on the
effective date of the Change in Control transaction. In addition, for purposes of the definition of
“Change in Control” a person engaged in the business as an underwriter of securities shall not be deemed
to be a “beneficial owner” of, or to “beneficially own”, any securities acquired through such person’s
participation in good faith in a firm commitment underwriting until the expiration of forty days after
the date of such acquisition.

         For purposes of this Section 8.3, the term Holding Company means an entity that becomes a
holding company for the Company or its business as part of any reorganization, merger, consolidation or
other transaction, provided that the outstanding shares of common stock of such entity and the combined
voting power of the then outstanding voting securities of such entity entitled to vote generally in the
election of directors is, immediately after such reorganization, merger, consolidation or other
transaction, beneficially owned, directly or indirectly, by all or substantially all of the individuals
and entities who were the beneficial owners of the outstanding shares of Common Stock and the combined
voting power of the outstanding voting securities, respectively, of the Company immediately prior to
such reorganization, merger, consolidation or other transaction in substantially the same proportions as
their ownership, immediately prior to such reorganization, merger, consolidation or other transaction,
of such outstanding voting stock.

SECTION 9. DEFERRED COMPENSATION PROGRAM.

         9.1 Election to Defer. On or before December 31 of any calendar year, an Eligible Director may
elect to defer receipt of all or any part of any Compensation payable in respect of the calendar year following
the year in which such election is made, and to have such amounts credited, in whole or in part, to a Stock Unit
Account or an Interest Account. Any person who shall become an Eligible Director during any calendar year may
elect, not later than the 30th day after his or her term as a Director begins, to defer payment of all or any part
of his or her Compensation payable for the portion of such calendar year following such election.

         9.2 Method of Election. A deferral election shall be made by written notice filed with the
Corporate Secretary of the Company. Such election shall continue in effect (including with respect to
Compensation payable for subsequent calendar years) unless and until the Eligible Director revokes or modifies
such election by written notice filed with the Corporate Secretary of the Company. Any such revocation or
modification of a deferral election shall become effective as of the end of the calendar year in which such notice
is given and only with respect to Compensation payable for services rendered thereafter. Amounts credited to the
Eligible Director’s Stock Unit Account prior to the effective date of any such revocation or modification of a
deferral election shall not be affected by such revocation or modification and shall be distributed only in
accordance with the otherwise applicable terms of the Plan. An Eligible Director who has revoked an election to
participate in the Plan may file a new election to defer Compensation payable for services to be rendered in the
calendar year following the year in which such election is filed.

         9.3 Investment Election. At the time an Eligible Director elects to defer receipt of Compensation
pursuant to Section 9.1, the Eligible Director shall designate in writing the portion of such Compensation, stated
as a whole percentage, to be credited to the Interest Account (or such other account as may be established from
time to time by the Committee) and the portion to be credited to the Stock Unit Account. If an Eligible Director
fails to notify the Corporate Secretary as to how to allocate any Compensation between the Accounts, 100% of such
Compensation shall be credited to the Interest Account. By written notice to the Corporate Secretary of the
Company, an Eligible Director may change the manner in which the Compensation payable with respect to services
rendered after the end of such calendar year are allocated among the Accounts.

         9.4 Dividend Equivalents. In addition to the deferral of Compensation permitted under Section 9.1,
an Eligible Director may elect, in the manner and at the time described in Section 5.3, to have Dividend
Equivalents payable in respect of his or her Units credited to his or her Interest Account in the manner and at
the time described in such Section 5.3.

         9.5 Interest Account. Any Compensation allocated to the Interest Account shall be credited to the
Interest Account as of the date such Fees would have been paid to the Eligible Director. Any amounts credited to
the Interest Account shall be credited with interest at the same rate and in the manner in which interest is
credited under the Fixed Investment Fund (or, if such fund no longer exists, the fund with the investment criteria
most clearly comparable to that of such Fund) under the Aetna Inc. Incentive Savings Plan (or any successor
thereto).

         9.6 Stock Unit Account. Any Compensation allocated to the Stock Unit Account shall be deemed to be
invested in a number of Units equal to the quotient of (i) such Compensation divided by (ii) the Fair Market Value
on the date the Fees then being allocated to the Stock Unit Account would otherwise have been paid. Fractional
Units shall be credited, but shall be rounded to the nearest hundredth percentile, with amounts equal to or
greater than .005 rounded up and amounts less than .005 rounded down. Whenever a dividend other than a dividend
payable in the form of Shares is declared with respect to the Shares, the number of Units in the Eligible
Director’s Stock Unit Account shall be increased by the number of Units

7

 

determined by dividing (i) the product of (A) the number of Units in the Eligible Director’s Stock Unit Account on
the related dividend record date, and (B) the amount of any cash dividend declared by the Company on a Share (or,
in the case of any dividend distributable in property other than Shares, the per share value of such dividend, as
determined by the Company for purposes of income tax reporting), by (ii) the Fair Market Value on the related
dividend payment date. In the case of any dividend declared on Shares which is payable in Shares, the Eligible
Director’s Stock Unit Account shall be increased by the number of Units equal to the product of (i) the number of
Units credited to the Eligible Director’s Stock Unit Account on the related dividend record date, and (ii) the
number of Shares (including any fraction thereof) distributable as a dividend on a Share.

         9.7 Distribution Election. At the time an Eligible Director makes a deferral election pursuant to
Section 9.1, the Eligible Director shall also file with the Corporate Secretary of the Company a written election
( a “Distribution Election”) with respect to whether:

         (i)  the aggregate amount, if any, credited to the Interest Account at any time and the value of any Units
credited to the Stock Unit Account shall be distributed in cash, in Shares or in a combination thereof at the
election of the Director;

         (ii)  such distribution shall commence as soon as practicable following the first business day of the
calendar month following the date the Eligible Director ceases to be a Director or on the first business day of
any calendar year following the calendar year in which the Eligible Director ceases to be a Director; and

         (iii)  such distribution shall be in one lump sum payment or in such number of annual installments (not to
exceed ten) as the Eligible Director may designate.

         The amount of any installment payment shall be determined by multiplying the amount credited to the
Accounts of an Eligible Director immediately prior to the distribution by a fraction, the numerator of which is
one and the denominator of which is the number of installments (including the current installment) remaining to be
paid. An Eligible Director may at any time, and from time to time, change any Distribution Election applicable to
his or her Accounts, provided that no election to change the timing of any final distribution shall be effective
unless it is made in writing and received by the Corporate Secretary of the Company at least one full calendar
year prior to the time at which the Eligible Director ceases to be a director.

         9.8 Financial Hardship Withdrawal. Any Eligible Director may, after submission of a written request
to the Corporate Secretary of the Company and such written evidence of the Eligible Director’s financial condition
as the Committee may reasonably request, withdraw from his Interest Account up to such amount as the Committee
shall determine to be necessary to alleviate the Eligible Director’s financial hardship.

         9.9 Timing and Form of Distributions. Any distribution to be made hereunder, whether in the form of
a lump sum payment or installments, following the termination of an Eligible Director’s service as a Director
shall commence in accordance with the Distribution Election made by the Eligible Director pursuant to Section
9.7. If an Eligible Director fails to specify a form of payment for a distribution in accordance with Section
9.7, the distribution from the Interest Account shall be made in cash and the distribution from the Stock Unit
Account shall be made in Shares. If an Eligible Director fails to specify in accordance with Section 9.7 a
commencement date for a distribution or whether such distribution shall be made in a lump sum payment or a number
of installments, such distribution shall be made in a lump sum payment and commence on the first business day of
the month immediately following the date on which the Eligible Director ceases to be a Director. In the case of
any distribution being made in annual installments, each installment after the first installment shall be paid on
the first business day of each subsequent calendar year, or as soon as practical thereafter, until the entire
amount subject to such Distribution Election shall have been paid.

8

 

         9.10 Effect on Prior Plan. Subject to approval of the Company’s sole shareholder and the
consummation of the transactions contemplated by the Merger Agreement, the amounts standing to the credit of each
Eligible Director’s stock unit account under the Prior Plan shall be transferred to the Plan and credited to the
Eligible Director’s Stock Unit Account. Any elections in effect under such Prior Plan shall be deemed to be an
election made pursuant to and in accordance with the terms of this Section 9 unless and until the Eligible
Director elects to change such elections in accordance with the provisions of this Section 9.

SECTION 10. UNFUNDED STATUS.

         The Company shall be under no obligation to establish a fund or reserve in order to pay the benefits
under the Plan. A Unit represents a contractual obligation of the Company to deliver Shares or pay cash to a
Director as provided herein. The Company has not segregated or earmarked any Shares or any of the Company’s
assets for the benefit of a Director or his/her beneficiary or estate, and the Plan does not, and shall not be
construed to, require the Company to do so. The Director and his/her beneficiary or estate shall have only an
unsecured, contractual right against the Company with respect to any Units granted or amounts credited to a
Director’s Accounts hereunder, and such right shall not be deemed superior to the right of any other creditor.
Units shall not be deemed to constitute options or rights to purchase Stock.

SECTION 11. AMENDMENT AND TERMINATION.

         The Plan may be amended at any time by the Board of Directors, provided that, except as provided in
Section 4.2, the Board of Directors may not, without approval of the shareholders of the Company increase the
number of Shares which may be awarded under the Plan. The Plan shall terminate on April 30, 2010.
Notwithstanding the foregoing, no amendment or termination of the Plan shall materially and adversely affect any
rights of any Director under any Grant made pursuant to the Plan. Unless the Board otherwise specifies at the
time of such termination, a termination of the Plan will not result in the distribution of the amounts credited to
an Eligible Director’s Accounts.

SECTION 12. OTHER STOCK-BASED AWARDS.

         The Board of Directors shall have authority to grant to Eligible Directors an “Other Stock-Based Award”,
which shall consist of any right which is (i) not a Grant described in Sections 5 or 7 above and (ii) a Grant of
Shares or a Grant denominated or payable in, valued in whole or in part by reference to, or otherwise based on or
related to, Shares (including, without limitation, securities convertible into Shares), as deemed by the Board of
Directors to be consistent with the purposes of the Plan; provided that any such rights must comply, to the extent
deemed desirable by the Board of Directors, with Rule 16b-3 and applicable law. Subject to the terms of the Plan
and any applicable award agreement, the Board of Directors shall determine the terms and conditions of any such
Other Stock-Based Award.

SECTION 13. GENERAL PROVISIONS.

         13.1 No Right to Serve as a Director. This Plan shall not impose any obligations on the Company to
retain any Eligible Director as a Director nor shall it impose any obligation on the part of any Eligible Director
to remain as a Director of the Company.

         13.2 Construction of the Plan. The validity, construction, interpretation, administration and effect
of the Plan, and the rights relating to the Plan, shall be determined solely in accordance with the laws of the
State of Connecticut.

9

 

         13.3 No Right to Particular Assets. Nothing contained in this Plan and no action taken pursuant to
this Plan shall create or be construed to create a trust of any kind or any fiduciary relationship between the
Company and any Eligible Director, the executor, administrator or other personal representative or designated
beneficiary of such Eligible Director, or any other persons. Any reserves that may be established by the Company
in connection with Units granted under this Plan shall continue to be treated as the assets of the Company for
federal income tax purposes and remain subject to the claims of the Company’s creditors. To the extent that any
Eligible Director or the executor, administrator, or other personal representative of such Eligible Director,
acquires a right to receive any payment from the Company pursuant to this Plan, such right shall be no greater
than the right of an unsecured general creditor of the Company.

         13.4 Listing of Shares and Related Matters. If at any time the Board of Directors shall determine in
its discretion that listing, registration or qualification of the Shares covered by this Plan upon any national
securities exchange or under any state or federal law, or the consent or approval of any governmental regulatory
body, is necessary or desirable as a condition of, or in connection with, the delivery of Shares under this Plan,
no Shares will be delivered unless and until such listing, registration, qualification, consent or approval shall
have been effected or obtained, or otherwise provided for, free of any conditions not acceptable to the Board of
Directors.

         13.5 Severability of Provisions. If any provision of this Plan shall be held invalid or
unenforceable, such invalidity or unenforceability shall not effect any other provisions hereof, and this Plan
shall be construed and enforced as if such provision had not been included.

         13.6 Incapacity. Any benefit payable to or for the benefit of a minor, an incompetent person or
other person incapable of receipting therefor shall be deemed paid when paid to such person’s guardian or to the
party providing or reasonably appearing to provide for the care of such person, and such payment shall fully
discharge any liability or obligation of the Board of Directors, the Company and all other parties with respect
thereto.

         13.7 Nontransferability. No Grant may be assigned or transferred, in whole or in part, either
directly or by operation of law (except in the event of an Eligible Director’s death by will or applicable laws of
descent and distribution), including, but not by way of limitation, by execution, levy, garnishment, attachment,
pledge, bankruptcy or in any other manner, and no such right or interest of any Eligible Director in the Plan
shall be subject to any obligation or liability of such Eligible Director.

         13.8 Headings and Captions. The headings and captions herein are provided for reference and
convenience only, shall not be considered part of this Plan, and shall not be employed in the construction of this
Plan.

         2. Piggyback Registrations.

                  (a) Right to Piggyback. Whenever the Company proposes to
register any of its securities under the Securities Act, other than in an
initial public offering or pursuant to a registration on Forms S-4 or S-8 (or
any successor form or forms), the Company will give not less than 20 days prior
written notice to each Holder of Registrable Securities of its intention to
effect such a registration and, subject to the provisions of subsection (b)
hereof and the Holder's obligations pursuant to Section 6(i) below, will include
in such registration all Registrable Securities with respect to which the Holder
has given notice of request for inclusion therein to the Company within 15 days
after the Company gives such notice (a "PIGGYBACK REGISTRATION"); provided, that
the Company shall have the right to postpone or withdraw any registration
effected pursuant to this Section 2(a) without obligation to any Holder.

                  (b) Priority on Piggyback Registration. In the event that any
Piggyback Registration is an underwritten public offering, the number of
Registrable Securities to be included in such an underwriting may be reduced pro
rata (based upon the number of securities requested to be registered) among (i)
the Holders of Registrable Securities who have requested registration of
Registrable Securities and (ii) any other persons with registration rights that
have been granted in compliance with Section 9 below ("SECTION 9 SECURITY
HOLDERS"), if and to the extent that the managing underwriter shall advise the
Company that such inclusion would adversely affect the marketing of the
securities to be sold by the Company therein, provided, however, that if any
shares are to be included in such underwriting for the account of any person
other than the Company, the Holders of Registrable Securities or Section 9
Security Holders, such shares of such other persons shall be reduced to zero
before any reduction shall be made in the number of Registrable Securities to be
included in such registration by all Holders of Registrable Securities.

         3. Demand Registrations. If at any time following the date that is one
hundred eighty (180) days after the closing of an initial public offering by the
Company, one or more of the Holders of an aggregate of not less than 25% of the
Registrable Securities ("INITIATING HOLDERS") then outstanding shall notify the
Company in writing that it or they intend to offer or cause to be offered for
public sale all or any portion of their Registrable Securities and requesting
that the Company cause such Registrable Securities to be registered under the
Securities Act ("DEMAND REQUEST"), the Company will notify all other Holders of
Registrable Securities (the "COMPANY NOTICE"). The Company shall file as soon as
practicable, and in any event within 60 days of the receipt of the Demand
Request, a registration statement, and use its best efforts to cause such
registration statement to

                                     - 5 -
<PAGE>

become effective, with respect to the registration of such Registrable
Securities as may be requested by the Initiating Holders and such other
Registrable Securities owned by any other Holders with respect to which the
Company has received written requests for inclusion within 20 days of the
Company Notice. Anything herein to the contrary notwithstanding, the Company
shall be obligated to comply with this Section 3 on one occasion only.
Notwithstanding the foregoing, if the Company shall furnish to the Initiating
Holder(s) a certificate signed by the Chief Executive Officer of the Company
stating that in the good faith judgment of the Board of Directors of the Company
it would be materially detrimental to the Company and its stockholders for such
registration statement to be filed and it is therefore desirable to defer the
filing of such registration statement, the Company shall have the right to defer
taking action with respect to such filing for a period of 90 days after receipt
of the Demand Request.

         4. Registration on Form S-3. At such time as the Company is qualified
to register its securities on Form S-3, and in addition to the rights contained
in Section 2, if at any time a Holder or Holders of Registrable Securities (the
"INITIATING FORM S-3 HOLDERS") requests that the Company file a registration
statement on Form S-3 for a sale or public offering of all or any portion of the
Registrable Securities held by such Initiating Form S-3 Holder or Holders (the
"FORM S-3 DEMAND"), the reasonably anticipated aggregate price to the public of
which would exceed $5,000,000, then the Company (a) will promptly give at least
20 days written notice of the proposed registration to all other Holders and (b)
use its best efforts to register under the Securities Act on Form S-3, for
public sale in accordance with the method of disposition specified in the Form
S-3 Notice, the number of Registrable Securities specified in such Form S- 3
Notice together with any Registrable Securities requested to be included by any
other Holders joining in such request as are specified in a written request
given within 15 days after receipt of such written notice from the Company.
Notwithstanding the foregoing, if the Company shall furnish to the Initiating
Form S-3 Holder(s) a certificate signed by the Chief Executive Officer of the
Company stating that in the good faith judgment of the Board of Directors of the
Company it would be materially detrimental to the Company and its stockholders
for such registration statement to be filed and it is therefore desirable to
defer the filing of such registration statement, the Company shall have the
right to defer taking action with respect to such filing for a period of 90 days
after receipt of the Form S-3 Demand.

         5. Holdback Agreements. Upon the request of the managing underwriter,
each Holder of Registrable Securities shall enter into an agreement whereby such
Holder agrees not to effect any public sale or distribution of equity securities
of the Company, or any securities convertible into or exercisable for such
securities, for a period not to exceed 180 days beginning on the effective date
of any underwritten registration in which such Holder's Registrable Securities
are included (except as part of such underwritten registration); provided, that
(a) in no event shall a holder of Registrable Securities be subject to a
limitation on sale or distribution that covers a period longer than that to
which any other security holder whose securities are included in the
registration is subject, and (b) the limitation set forth herein shall not apply
to any securities of the Company which are purchased in a public offering
registered under the Securities Act or in the open market following an initial
public offering by the Company.

                                     - 6 -

         6. Registration Procedures. Whenever the Holders of Registrable
Securities have requested that any Registrable Securities be registered pursuant
to this Restated Agreement, the Company will as expeditiously as reasonably
possible:

                  (a) prepare and file with the SEC a Registration Statement
with respect to such Registrable Securities and use its best efforts to cause
such Registration Statement to become effective and to remain continuously
effective for a period which will terminate when all Registrable Securities
covered by such Registration Statement, as amended from time to time, have been
sold or a period of 90 days, whichever is shorter;

                  (b) prepare and file with the SEC such amendments and
post-effective amendments to the Registration Statement and the Prospectus as
may be necessary to keep the Registration Statement effective for the period
specified in Section 6(a) and to comply with the provisions of the Securities
Act and the Exchange Act with respect to the distribution of all Registrable
Securities; provided that, at a time reasonably prior to the filing of a
Registration Statement or Prospectus, or any amendments or supplements thereto,
the Company will furnish to counsel for the Holders of Registrable Securities
included in such registration, copies of all documents proposed to be filed,
which documents will be subject to the comments of such counsel;

                  (c) make available for inspection by a representative of the
Holders of Registrable Securities, any underwriter participating in any
distribution pursuant to such registration, and any attorney, accountant or

cause the Company's officers, directors and employees to supply all information
reasonably requested by any such representative, underwriter, attorney,
accountant or agent in connection with such registration statement;

                  (d) notify the counsel for the Holders of Registrable
Securities included in such registration promptly, and, if requested, confirm
such advice in writing, (i) when the Prospectus or any supplement or
post-effective amendment has been filed, and with respect to the Registration

(ii) of any request by the SEC for amendments or supplements to the Registration
Statement or the Prospectus or for additional information, (iii) of the issuance
by the SEC of any stop order suspending the effectiveness of the Registration
Statement or the initiation of any proceedings for that purpose, and (iv) of the
receipt by the Company of any notification with respect to the suspension of the
qualification of the Registrable Securities for sale in any jurisdiction or the
initiation or threatening of any proceeding for such purpose;

                  (e) make reasonable commercial efforts to obtain the
withdrawal of any order suspending the effectiveness of the Registration
Statement;

                  (f) deliver to each Holder of Registrable Securities included
in such registration, as the case may be, as many copies of the Registration

                  (g) prior to any public offering of Registrable Securities,

jurisdictions as such Holder or any underwriter reasonably requests in writing,
and do any and all other acts or things necessary or advisable to enable the
distribution in such jurisdictions of the Registrable Securities covered by the
Registration Statement; provided that the Company will not be required to
qualify generally to do business in any jurisdiction where it is not then so
qualified or to take any action which would subject it to general service of
process in any such jurisdiction where it is not then so subject;

                  (h) cause all Registrable Securities covered by the
Registration Statement to be listed on each securities exchange, interdealer
quotation system or other market on which similar securities issued by the
Company are then listed; and provide a transfer agent and registrar for all
Registrable Securities included in such Registration Statement and a CUSIP
number for all such Registrable Securities, in each case not later than the
effective date of such registration;

                  (i) in the event of any underwritten public offering, enter
into and perform its obligations under an underwriting agreement, usual and
customary in form, with the managing underwriter of such offering (the Holders
of Registrable Securities included in such registration, shall also enter into
and perform their obligations under such agreement, usual and customary in
form); and the Company shall take such other actions as the underwriters
reasonably request in order to expedite or facilitate a disposition of the
Registrable Securities;

                  (j) upon request, furnish to each Holder of Registrable
Securities included in such registration, a signed counterpart, addressed to

date of such Registration Statement (or, if such registration includes an

Statement;

                  (k) immediately notify each Holder of Registrable Securities
included in such registration, at any time when a Prospectus relating thereto is
required to be delivered under the Securities Act, upon discovery that, or upon
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 the light of the
circumstances then existing, and at the request of any such Holder, promptly
prepare and furnish to such Holder 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, such Prospectus
shall not include an untrue statement of a material fact or omit to state a
material fact required to be stated therein or

                                     - 8 -

necessary to make the statements therein not misleading in the light of the
circumstances then existing;

Holders of Registrable Securities to be included in the registration will
furnish to the Company in writing such information with respect to themselves
and the proposed distribution by them as reasonably shall be necessary in order
to assure compliance with federal and applicable state securities laws. In
addition, the Holders of Registrable Securities agree that they will not deliver
any form of Prospectus in connection with the sale of any Registrable Securities
as to which the Company has advised such Holders that it is preparing an
amendment or supplement.

         7. Expenses. The Company will pay all expenses in connection with any
registration pursuant to Sections 2, 3 and 4, including, without limitation, all
registration and filing fees, printing expenses, fees and disbursements of
counsel and independent public accountants for the Company, fees and expenses
(including counsel fees) incurred in connection with complying with state
securities or "blue sky" laws, fees of the National Association of Securities
Dealers, Inc., transfer taxes, fees of transfer agents and registrars, costs of
insurance and fees and disbursements of one counsel for the Holders of
Registrable Securities (which counsel shall be selected by the Holders of a
majority of the Registrable Securities being included in the registration and
shall be reasonably acceptable to the Company); provided, that all underwriting
discounts and selling commissions applicable to the sale of a holder's
Registrable Securities will be paid by such holder.

         8. Indemnification.

                  (a) Indemnification by Company. In connection with any
registration pursuant to this Restated Agreement, the Company agrees to
indemnify and hold harmless, to the fullest extent permitted by law, each Holder
of Registrable Securities included in a registration pursuant to this Restated
Agreement, such Holder's officers, directors, partners and employees and each
person who controls such holder (within the meaning of the Securities Act) and
each underwriter, if any (including any broker or dealer which may be deemed an
underwriter) and each person who controls any underwriter of the Registrable
Securities against all losses, claims, damages, liabilities, and expenses caused
by (i) any untrue or alleged untrue statement of a material fact contained in
any Registration Statement, Prospectus or any preliminary prospectus or any
amendment or supplement thereto or any omission or alleged omission to state
therein a material fact required to be stated therein or necessary to make the
statements therein not misleading, or (ii) any violation by the Company of any
federal, state or common law, rule or regulation applicable to the Company in
connection with any Registration Statement, Prospectus or any preliminary
prospectus, or any amendment or supplement thereto, and shall reimburse, as
incurred, each of the foregoing persons for any legal and any other expenses

                                     - 9 -
<PAGE>

reasonably incurred in connection with investigating or defending any such
claims; provided, that the indemnity agreement contained in this subsection (a)
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
Company (which consent shall not unreasonably be withheld), nor shall the
Company be liable to the extent any loss, claim, damage, liability or action
arises out of or is based upon any information furnished in writing to the
Company by any Holder, underwriter or controlling person expressly for use in
connection with such registration.

                  (b) Indemnification by Holder of Registrable Securities. In
connection with any registration pursuant to the terms of this Restated
Agreement, each Holder of Registrable Securities included in such registration
agrees to indemnify and hold harmless, to the fullest extent permitted by law,
the Company, its directors and officers and each person who controls the Company
(within the meaning of the Securities Act) against any losses, claims, damages,
liabilities and expense resulting from any untrue statement of a material fact
or any omission of a material fact required to be stated in the Registration
Statement or Prospectus or preliminary prospectus or any amendment or supplement
thereto, or necessary to make the statements therein not misleading, to the
extent, but only to the extent, that such untrue statement or omission is
contained in any information furnished in writing by the Holder of Registrable
Securities to the Company specifically for inclusion in such Registration
Statement or Prospectus and that such information was substantially relied upon
by the Company in preparation of the Registration Statement or Prospectus or any
amendment or supplement thereto. In no event shall the liability of the Holder
of Registrable Securities hereunder be greater in amount than the lesser of (i)
an amount equal to the proportion that the public offering price of the
Registrable Securities sold by the holder in such registration bears to the
total public offering price of all securities sold thereunder or (ii) the dollar
amount of the proceeds (net of all expense paid by such Holder and the amount of
any damages such Holder has otherwise been required to pay by reason of such
untrue statement or omission) received by such Holder upon the sale of the
Registrable Securities pursuant to such registration; provided, however that the
indemnity agreement contained in this subsection (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 Holder (which consent shall
not unreasonably be withheld).

                  (c) Contribution. If for any reason the indemnification
provided for in the preceding clauses (a) and (b) is judicially determined (by
the entry of a final judgment or decree by a court of competent jurisdiction and
the expiration of time to appeal or the denial of the last right of appeal) to
be unavailable to an indemnified party or insufficient to hold it harmless,
notwithstanding the fact that this Section 8 provides for indemnification in
such case, then the indemnifying party shall contribute to the amount paid or
payable by the indemnified party as a result of such loss, claim, damage or
liability in such proportion as is appropriate to reflect the relative fault of
the indemnified party and the indemnifying party, as well as any other relevant
equitable considerations. The relative fault of the indemnifying party and of
the indemnified party shall be determined by reference to, among other things,
whether the untrue or alleged untrue statement of a material fact or the
omission to state a material fact relates to information supplied by the

                                     - 10 -
<PAGE>

indemnifying party or by the indemnified party and the parties' relative intent,
knowledge, access to information, and opportunity to correct or prevent such
statement or omission.

                  (d) Survival of Obligations. The obligations of the parties
under this Section 8 shall survive the completion of the offering of Registrable
Securities and shall remain in full force and effect regardless of any
investigation made by or on behalf of any indemnified party.

         9. Limitations on Subsequent Registration Rights. From and after the
date of this Restated Agreement, the Company shall not, without the prior
written consent of Holder(s) of at least fifty percent (50%) of all Registrable
Securities then held by all Holders, enter into any agreement with any holder or
prospective holder of any securities of the Company giving such holder or
prospective holder any registration rights the terms of which are more favorable
than the registration rights granted to the Holders hereunder.

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

         11. Rule 144 Reporting. With a view to making available the benefits of
certain rules and regulations of the Commission that may permit the sale of the
Registrable Securities to the public without registration, the Company agrees
to:

                  (a) make and keep public information available, as those terms
are understood and defined under the Securities Act, at all times from and after
90 days following the earlier of the effective date of the Company's first
registration under the Securities Act or the registration of any class of the
Company's securities under Section 12 of the Exchange Act;

                  (b) use its best efforts to file with the Commission in a
timely manner all reports and other documents required of the Company under the
Securities Act and the Exchange Act; and

                  (c) furnish to each Holder of Registrable Securities forthwith
upon request (i) a written statement by the Company as to its compliance with
the reporting requirements of Rule 144, the Securities Act and the Exchange Act,
(ii) a copy of the most recent annual or quarterly report of the Company, and
(iii) such other reports and documents so filed by the Company as such Holder
may reasonable request in availing itself of any rule or regulation of the
Commission allowing such holder to sell any Registrable Securities without
registration.

         12. Amendment and Restatement of Predecessor Agreements.

                  (a) Intent of Security Holders. Each Security Holder who
executes a counterpart signature page to this Restated Agreement consents and
agrees (i) to the amendment and restatement of each Predecessor Agreement to
which such Security Holder is a party as set forth in this Restated Agreement,
and (ii) that the rights and obligations of

                                     - 11 -
<PAGE>

the parties with respect to the registration of the Registrable Securities
shall, subject to Section 12(c) and Section 12(f) hereof, be governed solely by
this Restated Agreement.

                  (b) Holder Authority. Each Security Holder who executes a
counterpart signature page to this Restated Agreement certifies that he or she
has the requisite power and authority to enter into this Restated Agreement.

                  (c) Requisite Approvals; Timing of Effectiveness. This
Restated Agreement shall become effective as to each of the Predecessor
Agreements immediately upon the execution of this Restated Agreement by the
holders of the minimum number of Registrable Securities under such Predecessor
Agreement necessary to amend such Predecessor Agreement as set forth below:

                           (i) With respect to the 1995 Registration Rights
Agreements, the holders of at least fifty percent (50%) of the Common Stock
purchased by the investors participating in the 1995 Common Stock Offering.

                           (ii) With respect to the 1996 Registration Rights

                           (iv) With respect to the 1997 Sunrise Warrant

<PAGE>

                  (d) Validity of Restatement as to Each Predecessor Agreement.
Without limiting the foregoing, the failure to obtain the requisite signatures
with respect to any one or more of Predecessor Agreements shall not affect the
validity of this Restated Agreement with respect to any other Predecessor
Agreement for which such requisite signatures have been obtained.

                  (e) No Other Agreements. Each of the Security Holders
acknowledges and represents that such Security Holder is not a party to, or the
beneficiary of, any registration rights with respect to the Company's Common

such Predecessor Agreements in accordance herewith, this Restated Agreement.

                  (f) IPO Lock-Up Obligations to Remain Intact. Notwithstanding

Restated Agreement.

         13. Miscellaneous.

                  (a) Amendments and Waivers. This Restated Agreement may be
amended and the Company may take any action herein prohibited, or omit to
perform any act herein required to be performed by it, only if the Company shall
have obtained the written consent to such amendment, action or omission to act,
of the Holder or Holders of at least 50% of the Registrable Securities then held
by all Holders. Each Holder of any Registrable Securities at the time and any
subsequent Holder of Registrable Securities shall be bound by any consent
authorized by this subsection (a), whether or not such Registrable Securities
shall have been marked to indicate such consent.

                  (b) Assignments and Transfers. Each Holder of Registrable
Securities may make an assignment or transfer to any transferee or assignee of
any Registrable Securities, provided that (i) such transfer is made expressly
subject to this Restated Agreement and the transferee agrees in writing to be
bound by the terms and conditions hereof, and (ii) the Company is provided with
reasonably prompt written notice of such assignment.

                  (c) Entire Agreement. This Restated Agreement is intended by
the parties as a final expression of their agreement and is intended to be a
complete and exclusive statement of the agreement and understanding of the
parties hereto in respect of the subject matter contained herein. This Restated
Agreement supersedes all prior agreements and understandings between the parties
with respect to such subject matter.

                  (d) Governing Law. This Restated Agreement shall be governed
by, and construed in accordance with, the laws of the State of Delaware without
regard to principles of conflicts of law.

<PAGE>

                  (e) Notices. All notices and other communications provided for
or permitted hereunder shall be in writing and shall be deemed to have been duly
given and delivered (i) when delivered by hand, if personally delivered, (ii) if
sent by mail to a party whose address is in the same country as the sender, two
Business Days after being deposited in the mail, postage prepaid, (iii) when
delivered by courier as evidenced by receipt from the courier, if delivered by
courier, or (iv) if sent by facsimile transmission on a Business Day, upon
confirmation of receipt.

                  (f) Severability. Any provision of this Restated Agreement
which is prohibited or unenforceable in any jurisdiction will, as to such
jurisdiction, be ineffective to the extent of such prohibition or
unenforceability without invalidating the remaining portions hereof or affecting
the validity or enforceability of such provision in any other jurisdiction.

                  (g) Successors and Assigns. This Restated Agreement is binding
upon, and will inure to the benefit of, each of the parties and their respective
successors and permitted assigns.
