                       TELEDYNE TECHNOLOGIES INCORPORATED
                 PENSION EQUALIZATION/BENEFIT RESTORATION PLAN

         PURPOSE

         The purpose of the Teledyne Technologies Incorporated Pension
Equalization/Benefit Restoration Plan is to provide certain corporate employees
of Teledyne Technologies Incorporated who participate in qualified pension and
profit sharing plans with benefits and retirement income equal to that which
they would have received (i) but for the limitations imposed on plans which are
qualified within the meaning of Section 401(a) of the Code by Sections
401(a)(17), 401(k), 401(m), 402(g) or 415 of the Internal Revenue Code of 1986,
as amended, and (ii) but for participation in the Teledyne Technologies
Incorporated Executive Deferred Compensation Plan (the "Executive Deferred
Compensation Plan"), by supplementing, on an unfunded basis, amounts payable
under such qualified plans with amounts paid under this Plan.

         Allegheny Ludlum Corporation and, thereafter, Allegheny Teledyne
Incorporated ("ATI") sponsored a Benefit Restoration Plan for several years

adopted this Plan, permitted each participant in the Prior Plan hired by the

initial balance equal to his or her balance under the Prior Plan.

Corporation agrees to pay to the Participant, without requirement for
Participant contribution upon his retirement, a retirement benefit equal to the
difference between (a) and (b):

         (a)  the maximum life annuity to which the participant would be

              determined (i) without regard to the Limitations and (ii) by
              including as compensation for purposes of the Pension Plan formula

<PAGE>   4

         (b)  the life annuity which is actually paid to the participant under
              the Pension Plan after giving effect to the Limitations.

Notwithstanding any provision to the contrary, each participant who was a
participant in the Prior Plan shall be a Participant in this Plan with a Defined
Benefit Portion balance no less at any given time than his or her balance under
the Prior Plan.

         4.02 Elections and Calculations. Any election made by a Participant
pursuant to the Pension Plan relating to his benefit thereunder shall be deemed
an election hereunder and the Participant shall be deemed to have made the same
election hereunder without requirement of additional elections. All calculations
pursuant to the Defined Benefit Portion shall be consistent with those used in
determining benefits under the Pension Plan, including, but not limited to,
calculation of actuarial equivalents for optional forms of benefits and
reductions for early payment.

         4.03 Reports. The Corporation may, but shall not be required to, send
reports from time to time to each Participant regarding the amounts to which he
is entitled under this Plan.

         4.04 Payment of Restored Defined Benefit Portion Benefits. When a
Participant retires within the meaning of the Pension Plan or dies, the
Corporation shall pay to the Participant or his or her beneficiary, as the case
may be, the amounts determined under this Article IV in the same manner, at the
same times and frequencies and subject to the same terms and conditions (except
as set forth herein) which the Participant's benefits are paid under the Pension
Plan.

         ARTICLE V. DEFINED CONTRIBUTION PORTION

         5.01 Restoration of Savings Portion. The applicable, if any, of the
following amounts shall be credited to a Participant's Defined Contribution
Portion:

         (a)  Restoration of Deferrals for Effect of Limitations. In the event a
              Participant is deferring or contributing the maximum amount then
              permitted under the Limitations and such contributed amount is
              less than the amount which could be deferred or contributed by the
              Participant to the Corporation's defined contribution plan as then
              in effect without regard to the Limitations, the Participant's
              Defined Contribution Portion shall be credited with an amount
              equal to the difference between (i) the amount which would have
              been contributed as a Corporation matching contribution without
              regard to the Limitations and (ii) the amount actually contributed
              on the Participant's behalf as matching contributions.

         (b)  Restoration of Matching Contributions for Participation in the
              DCP. A Participant's Defined Contribution Portion shall be
              credited with an amount equal to the amount of Matching
              Contributions the Participant would have received on his or her
              deferrals, if any, to the DCP if such deferrals under the DCP were
              compensation for purposes of the Corporation's defined
              contribution plan as then in effect, the Participant

                                       4
<PAGE>   5

              contributed at the same rate with respect to the DCP deferrals as
              the rate then elected by the Participant for the defined
              contribution plan and the Limitations did not apply.

         5.02 Earnings. Balances in Participant's Defined Contribution Portion
shall be credited with earnings as of the last day of each calendar year at the
rate then in effect under one of the investment funds offered under the defined
contribution plan as determined from time to time by the Committee.

         5.03 Accounting. The Administrator shall establish on its records, for
bookkeeping purposes, an account for each Participant receiving credits under
this Deferred Contribution Portion to record the amount credited as
contributions under Section 5.01 and earnings, if any, pursuant to Section 5.02.
The Administrator shall post any contributions to such bookkeeping account
within thirty (30) days of the date a contribution would have been made to the
appropriate of the Plans under this Article V. The Administrator shall respond
to any inquiry of any Participant concerning the status of his account within
thirty (30) days of receipt thereof.

         5.04 No Withdrawals or Loans. No withdrawals of or loans against any
balance under the Plan may be made at any time by a Participant.

         5.05  Payment of Restored Defined Contribution Portion Benefit.

         (a) Death. In the event of a Participant's death, his then balance in
         his or her Defined Contribution Portion (including any Corporation
         contributions for such calendar year pursuant to Section 5.01 whether
         or not then actually made, net of withholding of applicable federal,
         state and local taxes) shall be distributed in a single cash payment to
         his beneficiary designated pursuant to the Corporation's defined
         contribution plan as then in effect as soon as administratively
         feasible after the Administrator receives notice of such death.

         (b) Disability, Retirement or Other Severance from Service. In the
         event of the Participant's Disability, Retirement or other severance
         from service, his then balance in his or her Defined Contribution
         Portion (including Corporation contributions for such calendar year
         pursuant to Section 5.01 whether or not then actually made, net of
         withholding or applicable federal, state and local income tax) shall be
         distributed in a single cash payment to him as soon as administratively
         feasible after the Administrator receives notice of such event;
         provided, however, with the consent of the Administrator, the
         Participant may elect in the tax year of the Participant prior to the
         tax year in which the distribution is then due to be made or to
         commence to receive such amount at a later time and/or in a different
         form of payment.

of benefits hereunder shall be made by the Corporation from general assets and
the Corporation will not be obligated to establish any special or separate fund
or make other segregation of assets to assure the payment of any benefits
hereunder. In the event the Corporation establishes any fund or segregation, no
party who is or becomes entitled to receive amounts hereunder shall have any
right to assert any claim, levy or lien thereon or assert any right thereto
unless such right is specifically set forth in writing. The rights of any party
to receive payments of any benefits hereunder shall be no greater than the
rights of an unsecured creditor of the Corporation.

receive benefits hereunder shall be physically or mentally incapable of
receiving or acknowledging receipt of any payment of benefits, the Corporation,
upon the receipt of satisfactory evidence that such incapacitated person is so
incapacitated and that another person or institution is maintaining him or her
and that no guardian or committee has been appointed for him or her, may provide
for such payment of benefits hereunder to such person or institution maintaining
him or her, and such payments so made shall be deemed for every purpose to have
been made to such incapacitated person.

present or future officer or director of the Corporation shall be personally
liable to any Participant, beneficiary or other person under any provision of
this Plan.

         10.04 Assets Owned by the Corporation. Nothing contained herein shall
be deemed to give any Participant or his beneficiary any interest in any
specific property of the Corporation or any right except to receive such
distributions as are expressly provided for in this Plan.

         10.05 Withholding. The payment of any benefits under this Plan shall be
net of any federal, state and local taxes that the Corporation is required to
withhold.

<PAGE>   5

         (b) Number of Registrations. The holders of Phillips Registrable
Securities will be entitled to request an aggregate of two Phillips Demand
Registrations. For purposes of this Section 3(b), a registration initiated as a
Phillips Demand Registration will not constitute a Phillips Demand Registration
(i) unless such registration is declared effective by the SEC and remains
effective for the period set forth in Section 7(a)(iii); provided, however, that
a registration which does not become effective after the Corporation has filed a
registration statement in accordance with the provisions hereof by reason of the
refusal to proceed of the initiating holders or such of the initiating holders
as would result in the inclusion of less than 3% of the then outstanding Common
Stock (other than any refusal to proceed (x) based upon the advice of their
counsel that the registration statement, or the prospectus contained therein,
contains an untrue statement of a material fact or omits to state a material
fact required to be stated therein or necessary to make the statements therein
not misleading in light of the circumstances then existing, or that such
registration statement or such prospectus, or the distribution contemplated
thereby, otherwise violates or would, if such distribution using such prospectus
took place, violate any applicable state or federal securities law or (y)
following a material breach by the Corporation of its obligations hereunder, but
only if such breach has materially and adversely affected the initiating
holder's ability to consummate the proposed offering or the pricing of such
offering) shall be deemed to have been effected; (ii) if after such registration
has been declared effective by the SEC it is subject to any stop order,
injunction or other adverse order or action of the SEC or other governmental
authority which is not removed within 15 days; or (iii) if such registration is
withdrawn as a result of the withdrawal of the demand pursuant to Section 3(g)
hereof prior to the filing by the Corporation of a registration statement with
the SEC.

         (c) Limitation on Rights of Corporation or Other Securityholders to
Piggyback on Phillips Demand Registrations. Neither the Corporation nor any of
its securityholders (other than the holders of Phillips Registrable Securities
in such capacity) has any right to include any of the Corporation's securities
in a registration statement initiated as a Phillips Demand Registration under
this Section 3 if such Demand Registration is an underwritten offering unless
(i) such securities are of the same class as the Phillips Registrable Securities
being registered, (ii) the managing underwriters agree that some or all of such
securities can be included without adversely affecting such offering or offering
price, and (iii) the Corporation, or the selling securityholders, as applicable,
agree to sell their securities on the same terms and conditions as apply to the
Phillips Registrable Securities and the holders of such Phillips Registrable
Securities. If any securityholders of the Corporation (other than the holders of
Phillips Registrable Securities in such capacity) register securities of the
Corporation in a Phillips Demand Registration (in accordance with the provisions
of this Section 3(c)), such securityholders will pay the fees and expenses of
counsel to such securityholders and their pro rata share of the Registration
Expenses if such pro rata share of the Registration Expenses for such
registration are not paid by the Corporation for any reason. The Corporation and
any such securityholders may withdraw their securities from a Phillips Demand
Registration; provided, however, if the Phillips Demand Registration is an
underwritten offering, they may do so only on the reasonable and customary terms
agreed upon by the managing underwriters for such offering.

         (d) Priority on Phillips Demand Registrations. If a Phillips Demand
Registration is an underwritten offering and the managing underwriters advise
the Corporation and the selling holders of the Phillips Registrable Securities
in writing that in their opinion the number of

                                      -4-
<PAGE>   6

Phillips Registrable Securities requested to be included exceeds the number of
securities which can be sold in such offering without adversely affecting the
proposed offering or the offering price, the Corporation will include in such
registration the number of Phillips Registrable Securities which in the opinion
of such underwriters can be sold without adversely affecting the proposed
offering or the offering price, and such securities will be allocated pro rata
among the holders of Phillips Registrable Securities requesting to be included
in the registration on the basis of the number of the Phillips Registrable
Securities requested to be included in such registration by their respective
holders. If securities (other than Phillips Registrable Securities) are proposed
to be included by the Corporation or its other securityholders in a Phillips
Demand Registration which is an underwritten offering (subject to and in
accordance with the provisions of Section 3(c)) and the managing underwriters
advise the Corporation and the selling holders of Phillips Registrable
Securities in writing that some but not all of said other securities can be sold
without adversely affecting the proposed offering or the offering price in such
underwritten offering, in addition to all of the Phillips Registrable Securities
being registered, those securities which are permitted to be included will be
allocated (i) first, to the Corporation, (ii) second, to the holders of Duke
Registrable Securities, allocated pro rata among the holders of Duke Registrable
Securities requesting to be included in the registration on the basis of the
number of Duke Registrable Securities requested to be included in such
registration by their respective holders and (iii) third, to the other
securityholders, allocated among them in such proportions as such
securityholders and the Corporation may agree.

         (e) Selection of Underwriters. If any Phillips Demand Registration is
an underwritten offering, or a best efforts underwritten offering, the
investment banker or investment bankers and manager or managers that will
administer the offering will be selected by the holders of two-thirds (by number
of shares) of the Phillips Registrable Securities requested to be included in
such offering; provided, however, such investment bankers and managers must be
reasonably satisfactory to the Corporation.

         (f) Other Registration Rights Agreements. Without the prior written
consent of the holders of a Majority of the Phillips Registrable Securities, the
Corporation will not enter into any agreement with any holder or prospective
holder of any securities of the Corporation which grants to such holder or
prospective holder any registration rights unless such agreement and the rights
granted thereunder are subject and subordinate to the rights of holders
hereunder.

         (g) Withdrawal by Holders of Phillips Registrable Securities. The
holders of Phillips Registrable Securities may withdraw a Phillips Demand
Request at any time and under any circumstances.

4. DEMAND REGISTRATION WITH RESPECT TO DUKE REGISTRABLE SECURITIES.

         (a) Requests for Registration. Subject to the provisions of Section
4(b), at any time after 180 days following the closing of the IPO any holder or
holders of a Majority of the then outstanding Duke Registrable Securities may
request a registration by the Corporation under the Securities Act of all or
part of its or their Duke Registrable Securities (a "Duke Demand Registration");
provided that the number of Duke Registrable Securities requested to be
registered represents at least 3% of the Corporation's then outstanding Common
Stock. Within 15 days after receipt of such request, the Corporation will
provide written notice of such

                                      -5-
<PAGE>   7

registration request to all holders of Registrable Securities and will, subject
to the provisions of Section 4(b) and Section 4(d), include in such registration
all Duke Registrable Securities with respect to which the Corporation has
received written requests for inclusion therein within 15 days after
distribution to the applicable holder of the Corporation's notice. All requests
made pursuant to this Section 4(a) will specify the amount of Registrable
Securities to be registered and will also specify the intended method of
disposition thereof; provided, however, that such method of disposition will be
limited to an underwritten offering if so requested by the holders of the Duke
Registrable Securities who initiated the request.

         (b) Number of Registrations. The holders of Duke Registrable Securities
will be entitled to request an aggregate of two Duke Demand Registrations. For
purposes of this Section 4(b), a registration initiated as a Duke Demand
Registration will not constitute a Duke Demand Registration (i) unless such
registration is declared effective by the SEC and remains effective for the
period set forth in Section 7(a)(iii); provided, however, that a registration
which does not become effective after the Corporation has filed a registration
statement in accordance with the provisions hereof by reason of the refusal to
proceed of the initiating holders or such of the initiating holders as would
result in the inclusion of less than 3% of the then outstanding Common Stock
(other than any refusal to proceed (x) based upon the advice of their counsel
that the registration statement, or the prospectus contained therein, contains
an untrue statement of a material fact or omits to state a material fact
required to be stated therein or necessary to make the statements therein not
misleading in light of the circumstances then existing, or that such
registration statement or such prospectus, or the distribution contemplated
thereby, otherwise violates or would, if such distribution using such prospectus
took place, violate any applicable state or federal securities law or (y)
following a material breach by the Corporation of its obligations hereunder, but
only if such breach has materially and adversely affected the initiating
holder's ability to consummate the proposed offering) shall be deemed to have
been effected; (ii) if after such registration has been declared effective by
the SEC it is subject to any stop order, injunction or other adverse order or
action of the SEC or other governmental authority which is not removed within 15
days; or (iii) if such registration is withdrawn as a result of the withdrawal
of the demand pursuant to Section 4(g) hereof prior to the filing by the
Corporation of a registration statement with the SEC.

         (c) Limitation on Rights of Corporation or Other Securityholders to
Piggyback on Duke Demand Registrations. Neither the Corporation nor any of its
securityholders (other than the holders of Duke Registrable Securities in such
capacity) has any right to include any of the Corporation's securities in a
registration statement initiated as a Demand Registration under this Section 4
if such Demand Registration is an underwritten offering unless (i) such
securities are of the same class as the Duke Registrable Securities being
registered, (ii) the managing underwriters agree that some or all of such
securities can be included without adversely affecting such offering or offering
price, and (iii) the Corporation, or the selling securityholders, as applicable,
agree to sell their securities on the same terms and conditions as apply to the
Duke Registrable Securities and the holders of such Duke Registrable Securities.
If any securityholders of the Corporation (other than the holders of Duke
Registrable Securities in such capacity) register securities of the Corporation
in a Duke Demand Registration (in accordance with the provisions of this Section
4(c)), such securityholders will pay the fees and expenses of counsel to such
securityholders and their pro rata share of the Registration Expenses if such
pro rata share of the Registration Expenses for such registration are not paid
by the Corporation for

                                      -6-
<PAGE>   8

any reason. The Corporation and any such securityholders may withdraw their
securities from a Duke Demand Registration; provided, however, if the Duke
Demand Registration is an underwritten offering, they may do so only on the
reasonable and customary terms agreed upon by the managing underwriters for such
offering.

         (d) Priority on Duke Demand Registrations. If a Duke Demand
Registration is an underwritten offering and the managing underwriters advise
the Corporation and the selling holders of the Duke Registrable Securities in
writing that in their opinion the number of Duke Registrable Securities
requested to be included exceeds the number of securities which can be sold in
such offering without adversely affecting the proposed offering or the offering
price, the Corporation will include in such registration the number of Duke
Registrable Securities which in the opinion of such underwriters can be sold
without adversely affecting the proposed offering or the offering price, and
such securities will be allocated pro rata among the holders of Duke Registrable
Securities requesting to be included in the registration on the basis of the
number of the Duke Registrable Securities requested to be included in such
registration by their respective holders. If securities (other than Duke
Registrable Securities) are proposed to be included by the Corporation or its
other securityholders in a Duke Demand Registration which is an underwritten
offering (subject to and in accordance with the provisions of Section 4(c)) and
the managing underwriters advise the Corporation and the selling holders of Duke
Registrable Securities in writing that some but not all of said other securities
can be sold without adversely affecting the proposed offering or the offering
price in such underwritten offering, in addition to all of the Duke Registrable
Securities being registered, those securities which are permitted to be included
will be allocated (i) first, to the Corporation, (ii) second, to the holders of
Phillips Registrable Securities, allocated pro rata among the holders of
Phillips Registrable Securities requesting to be included in the registration on
the basis of the number of Phillips Registrable Securities requested to be
included in such registration by their respective holders and (iii) third, to
the other securityholders, allocated among them in such proportions as such
securityholders and the Corporation may agree.

         (e) Selection of Underwriters. If any Duke Demand Registration is an
underwritten offering, or a best efforts underwritten offering, the investment
banker or investment bankers and manager or managers that will administer the
offering will be selected by the holders of two-thirds (by number of shares) of
the Duke Registrable Securities requested to be included in such offering;
provided, however, such investment bankers and managers must be reasonably
satisfactory to the Corporation.

         (f) Other Registration Rights Agreements. Without the prior written
consent of the holders of a Majority of the Duke Registrable Securities, the
Corporation will not enter into any agreement with any holder or prospective
holder of any securities of the Corporation which grants to such holder or
prospective holder any registration rights unless such agreement and the rights
granted thereunder are subject and subordinate to the rights of holders
hereunder.

         (g) Withdrawal by Holders of Duke Registrable Securities. The holders
of Duke Registrable Securities may withdraw a Duke Demand Request at any time
and under any circumstances.

5. PIGGYBACK REGISTRATIONS.

         (a) Right to Piggyback. If at any time after consummation of the IPO
the Corporation proposes to register any securities under the Securities Act in
connection with the public offering of such securities (other than a
registration relating to employee benefit plans or a corporate reorganization or
acquisition, or a registration on any form that does not permit inclusion of
sales of Registrable Securities) (a "Piggyback Registration"), the Corporation
will give written notice to all holders of Registrable Securities of its
intention to effect such a registration not later than the earlier to occur of
(i) 10 days following receipt by the Corporation of notice of exercise of demand
registration rights or (ii) 30 days prior to the anticipated filing date;
provided, that such notice indicate the number of shares proposed to be
registered, the proposed means of distribution of such securities and the
proposed managing underwriters of such offering; provided, however, that the
Corporation shall not be required to give such notice or to include any
Registrable Securities in a Piggyback Registration unless the Registrable
Securities to be so included are of the same class as the other securities to be
included in such registration. Subject to the provisions of Sections 5(b) and
(c), the Corporation will include in such Piggyback Registration all Registrable
Securities with respect to which the Corporation has received written requests
for inclusion therein within 15 days after delivery of the Corporation's notice.
The holders of Registrable Securities will be permitted to withdraw all or any
part of such holder's Registrable Securities from a Piggyback Registration at
any time prior to the date such Piggyback Registration becomes effective with
the SEC; provided, however, if the Piggyback Registration is an underwritten
offering, the holders of Registrable Securities may do so only on the reasonable
and customary terms agreed upon by the managing underwriters for such offering.
If a Piggyback Registration is an underwritten offering effected under (i)
Section 5(b), all Persons whose securities are included in the Piggyback
Registration will be obligated to sell their securities on the same terms and
conditions as apply to the securities being issued and sold by the Corporation
or (ii) Section 5(c), all Persons whose securities are included in the Piggyback
Registration will be obligated to sell their securities on the same terms and
conditions as apply to the securities being sold by the Person or Persons who
initiated the Piggyback Registration under Section 5(c). The foregoing
notwithstanding, if, at any time after giving written notice of a Piggyback
Registration but prior to the effective date of the registration statement filed
in connection therewith, the Corporation shall determine for any reason not to
register the securities described in its notice of its intention to file a
registration statement, the Corporation may, at its election, give written
notice of such determination to the holders of Registrable Securities and
thereupon shall be relieved of its obligation to register any Registrable
Securities in such registration.

         (b) Priority on Primary Registrations. If a Piggyback Registration is
an underwritten primary registration on behalf of the Corporation, and the
managing underwriters advise the Corporation in writing that in their opinion
the total number of securities requested to be included in such registration
exceeds the number of securities which can be sold in such offering without
adversely affecting the offering or the offering price, the Corporation will
include in such registration: first, all securities the Corporation proposes to
sell, then, to the extent that additional securities can, in the opinion of such
underwriters, be included in such registration without adversely affecting the
offering or the offering price, (i) first, up to the full number of securities
requested to be included in such registration by holders of Registrable
Securities allocated pro rata among such holders on the basis of the number of
securities requested to be

                                      -8-
<PAGE>   10

included therein by each such holder, (ii) second, up to the full number of
securities requested to be included in such registration by other holders of
securities entitled to include securities in such Piggyback Registration, and
(iii) third, such additional securities as may be agreed upon by the Corporation
and any other securityholders.

         (c) Priority on Secondary Registrations. If a Piggyback Registration is
an underwritten secondary registration on behalf of holders of the Corporation's
securities pursuant to the exercise of such holders' demand registration rights
or otherwise, and the managing underwriters advise the Corporation in writing
that in their opinion the number of securities requested to be included in such
registration exceeds the number of securities which can be sold in such offering
without adversely affecting the offering or the offering price, the Corporation
will include in such registration (i) first, the number of securities proposed
to be included therein on behalf of the holders of the Corporation's securities
exercising demand registration rights, allocated among the holders of such
securities in such proportions as the Corporation and such holders may agree,
(ii) second, up to the full number of securities the Corporation proposes to
sell, (iii) third, to the extent that additional securities can, in the opinion
of such underwriters, be included in such registration without adversely
affecting the offering or the offering price, up to the full number of
securities requested to be included in such registration by the holders of
Registrable Securities and other holders of securities entitled to include
securities in such Piggyback Registration, allocated pro rata among such holders
on the basis of the number of securities requested to be included therein by
each such holder and (iv) fourth, any additional securities that may be included
in such registration, in the opinion of such underwriters, without adversely
affecting the offering or the offering price, as may be agreed upon by the
Corporation and any other securityholders.

         (d) Selection of Underwriters. If any Piggyback Registration is an
underwritten offering, as between the Corporation and the holders of the
Registrable Securities, the Corporation will have the sole right to select the
investment banker or investment bankers and manager or managers to administer
the offering.

         (e) Limitation. No Piggyback Registration effected under this Section 5
(i) shall be deemed to constitute a Demand Registration or to have been effected
pursuant to Section 3 or Section 4 hereof or (ii) shall release the Corporation
of its obligations to effect any Demand Registration upon request as provided
under Section 3 or Section 4 hereof.

6. DEFERRAL OF FILING; PREEMPTION.

         (a) Deferral of Filing. Anything herein to the contrary
notwithstanding, the Corporation may defer the filing of any registration
statement otherwise required to be filed by it pursuant to Section 3 or 4 for up
to 180 days if the Corporation notifies each requesting holder promptly after
such request that the Corporation's Board of Directors has determined in its
good faith judgement that the requested registration and offering would require
disclosure of pending or contemplated matters or information, the disclosure of
which would likely be detrimental to the Corporation or materially interfere
with its business or a pending or contemplated material transaction involving
the Corporation. In addition to the foregoing deferral rights, the Corporation
shall not be required to file any registration statement pursuant to Section 3
or 4 (i) within 120 days after the effectiveness of a registration statement
relating to a Demand

                                      -9-
<PAGE>   11

Registration or (ii) within 180 days (or such shorter period as may be agreed to
by the underwriters but in no event less than 120 days) after the effectiveness
of a registration statement referred to in Section 5.

         (b) Preemption by the Corporation. Anything herein to the contrary
notwithstanding, in the event the Corporation reasonably expects to file, within
60 days of a demand for registration, a registration statement pertaining to
securities for the account of the Corporation (except a registration statement
on Form S-4 or Form S-8 or with respect to a transaction subject to Rule 145
under the Securities Act) then such request shall constitute a request made
pursuant to Section 5 hereof to include in such registration statement all
Registrable Securities subject to such request and the Corporation shall not be
obligated to file a separate registration statement for the Registrable
Securities subject to such request; provided, that the Corporation is actively
employing in good faith all reasonable efforts to cause such registration
statement to become effective.

         (c) Termination of Deferral Period. In the case of a deferral pursuant
to Section 6(a), the deferral period shall terminate upon the earlier of the
completion or abandonment of the relevant securities offering or sale,
Corporation business or other pending or contemplated material transaction.
After the termination or expiration of any deferral period and without further
request from the holders of Registrable Securities, the relevant Demand
Registration shall be reinstated, and the Corporation shall effect the filing of
the relevant Demand Registration unless the initiating holders shall have, prior
to the filing of such registration, withdrawn the initial request.

7. REGISTRATION PROCEDURES.

         (a) Subject to the terms hereof, whenever the holders of Registrable
Securities have requested that any Registrable Securities be registered in
accordance with the terms and conditions of this Agreement, the Corporation will
use its reasonable best efforts to effect the registration and to permit the
sale of such Registrable Securities in accordance with the intended method of
disposition thereof, and pursuant thereto the Corporation will promptly:

                  (i) prepare and file with the SEC, subject to the availability
         of all required consents of independent accountants (which the
         Corporation agrees to use all reasonable efforts to obtain), not later
         than 60 days after receipt of a request to file a registration
         statement with respect to such Registrable Securities, a registration
         statement with respect to such Registrable Securities, and use its
         reasonable best efforts to cause such registration statement to become
         effective; provided, that each such registration statement will be on a
         form for which the Corporation then qualifies, which is available for
         the sale of the Registrable Securities in accordance with the intended
         method of disposition thereof, and will provide for the registration of
         at least such number of shares as shall have been demanded be
         registered; provided, however, that before filing a registration
         statement or prospectus or any amendments or supplements thereto, the
         Corporation will furnish to each of the holders including shares
         therein, and the managing underwriters, if any, draft copies of all
         such documents proposed to be filed a reasonable period prior to such
         filing, which documents will be subject to the reasonable review of
         each of such holders, and the managing underwriters, if any, and their
         respective agents and

                                      -10-
<PAGE>   12

         representatives and (x) the Corporation will not include in any
         registration statement information concerning or relating to the
         holders including shares therein to which any such holder shall
         reasonably object in writing (unless the inclusion of such information
         is required by applicable law or the regulations of any securities
         exchange to which the Corporation may be subject or is required to
         prevent a material omission or misstatement in the filing), and (y)
         with respect to any Duke Demand Registration or Phillips Demand
         Registration, respectively, the Corporation will not file any Demand
         Registration or amendment thereto or any prospectus or any supplement
         thereto to which Duke or Phillips, respectively, shall reasonably
         object in writing;

                  (ii) notify each seller of Registrable Securities of any stop
         order issued by the SEC and take all reasonable actions required to
         prevent the entry of such stop order or to remove it at the earliest
         possible time if entered;

                  (iii) prepare and file with the SEC 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 a period of not less than 90 days, or such
         shorter period as may be required if all Registrable Securities covered
         by such registration statement are sold prior to the expiration of such
         90-day period (except in connection with an underwritten offering, in
         which case such registration statement shall be kept effective as long
         as the underwriters reasonably request in the underwriting agreement),
         and comply with the provisions of the Securities Act with respect to
         the disposition of all securities covered by such registration
         statement during such period in accordance with the intended methods of
         disposition by the sellers thereof set forth in such registration
         statement;

                  (iv) furnish without charge to each seller and managing
         underwriters of Registrable Securities such number of copies of such
         registration statement, each amendment and supplement thereto (in each
         case including all exhibits thereto), the prospectus included in such
         registration statement (including each preliminary, final, summary,
         amended or supplemented prospectus) and such other documents as such
         seller and managing underwriters may reasonably request in order to
         facilitate the disposition of the Registrable Securities owned by such
         seller;

                  (v) use its reasonable best efforts to register or qualify
         such Registrable Securities under such other securities or blue sky
         laws of such jurisdictions within the United States as any seller
         reasonably requests, keep such registrations or qualifications in
         effect for so long as the registration statement remains in effect, and
         do any and all other acts and things which may be reasonably necessary
         or advisable to enable such seller to consummate the disposition in
         such jurisdictions of the Registrable Securities owned by such seller;
         provided, however, that the Corporation 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 Section 7(a)(v), (ii)
         subject itself to taxation in any such jurisdiction or (iii) consent to
         general service of process in any such jurisdiction;

                  (vi) use its reasonable best efforts to cause the Registrable
         Securities covered by such registration statement to be registered with
         or approved by such other

                                      -11-
<PAGE>   13

         governmental agencies or authorities within the United States as may be
         necessary to enable the seller or sellers thereof to consummate the
         disposition of such Registrable Securities;

                  (vii) notify each seller of such Registrable Securities, at
         any time when a prospectus relating thereto is required to be delivered
         under the Securities Act, of the happening of any event of which the
         Corporation is aware as a result of which the prospectus included in
         such registration statement or any document incorporated therein by
         reference contains an untrue statement of a material fact or omits to
         state any material fact necessary to make the statements therein not
         misleading in light of the circumstance then existing, and prepare and
         file promptly with the SEC a supplement or amendment to such prospectus
         or any such document incorporated therein by reference so that, as
         thereafter delivered to the purchasers of such Registrable Securities,
         such prospectus will not contain an untrue statement of a material fact
         or omit to state any material fact necessary to make the statements
         therein not misleading in light of the circumstance then existing;

                  (viii) use its reasonable best efforts to cause all such
         Registrable Securities to be listed on each securities exchange on
         which similar securities issued by the Corporation are then listed or
         traded;

                  (ix) provide a transfer agent and registrar for all
         Registrable Securities and a CUSIP number for all such Registrable
         Securities, in each case not later than the effective date of such
         registration statement;

                  (x) enter into such customary agreements (including an
         underwriting agreement in customary form with customary lock-up
         provisions not to exceed 90 days from the date of the prospectus) and
         take such other actions in connection therewith as the holders of a
         Majority of the Registrable Securities being registered or the managing
         underwriters, if any, reasonably request in order to expedite or
         facilitate the disposition of such Registrable Securities; and make
         such representations and warranties with respect to the registration
         statement, post-effective amendment or supplement thereto, prospectus
         or any amendment or supplement thereto, and documents incorporated by
         reference, if any, to the managing underwriters of the Registrable
         Securities, in form, substance and scope as are customarily made by the
         Corporation in connection with offerings of Registrable Securities in
         transactions of such kind;

                  (xi) make available for inspection by any underwriter
         participating in any disposition pursuant to such registration
         statement, and any attorney, accountant or other agent retained by any
         such underwriter, all financial and other records, pertinent corporate
         documents and properties of the Corporation, and cause the
         Corporation's officers, directors and employees and accountants to
         supply all information reasonably requested by any such underwriter,
         attorney, accountant or agent in connection with such registration
         statement, in each case upon receipt of an appropriate confidentiality
         agreement;

                                      -12-
<PAGE>   14

                  (xii) in the case of an underwritten offering, obtain a cold
         comfort letter from the Corporation's independent public accountants in
         customary form and covering such matters of the type customarily
         covered by cold comfort letters, as the managing underwriters
         reasonably request; and

                  (xiii) otherwise use its reasonable best efforts to comply
         with all applicable rules and regulations of the SEC, and generally
         make available to its security holders, as soon as reasonably
         practicable, an earnings statement covering the period of at least
         twelve months, but not more than eighteen months, beginning with the
         first month after the effective date of the Registration Statement,
         which earnings statement will satisfy the provisions of Section 11(a)
         of the Securities Act and may be prepared in accordance with Rule 158
         under the Securities Act.

         (b) The Corporation may require each seller of Registrable Securities
as to which any registration is being effected to furnish to the Corporation in
writing such information regarding the seller and the distribution of such
securities as the Corporation may from time to time reasonably request and to
timely complete and execute all questionnaires, powers of attorney, indemnities,
hold-back agreements, underwriting agreements and other documents reasonably
requested by the Corporation.

9. INDEMNIFICATION; CONTRIBUTION.

         (a) Indemnification by Corporation. In the event any Registrable
Securities are included in a registration statement pursuant to this Agreement,
the Corporation shall indemnify and hold harmless each holder of such
Registrable Securities, its employees, officers, directors and constituent
partners and each Person who controls such holder (within the meaning of the
Securities Act and the Exchange Act) against all losses, claims, damages,
liabilities and expenses (or actions in respect thereof) arising out of or based
upon any untrue or alleged untrue statement of a material fact contained in any
registration statement or preliminary or final prospectus relating to the
registration of such Registrable Securities or any amendment or supplement
thereto or any document incorporated by reference therein or any omission or
alleged omission to state therein a material fact required to be stated therein
or necessary to make the statements therein, in light of the circumstances in
which they were made, not misleading, except insofar as the same are contained
in any information furnished in writing to the Corporation by or on behalf of
such holder or other indemnified Person expressly for use therein or caused by
such holder's failure to deliver a copy of the registration statement or
prospectus or any amendments or supplements thereto after the Corporation has
furnished such holder with a sufficient number of copies of the same. Subject to
the provisions of Section 9(c), the Corporation will reimburse each holder of
Registrable Securities, its officers, directors, constituent partners and
controlling Persons for any reasonable legal and other expenses as incurred in
connection with investigating or defending any such losses, claims, damages,
liabilities, expenses or actions for which such Person is entitled to
indemnification hereunder. In connection with a firm commitment or best efforts
underwritten offering, the Corporation will indemnify the underwriters or
agents, their officers, directors, constituent partners and each Person who
controls such underwriters (within the meaning of the Securities Act and the
Exchange Act) or agents to the same extent as provided above (or such greater
extent as may be customarily required by the managing underwriters) with respect
to the indemnification of the holders of Registrable Securities.

         (b) Indemnification by Holder of Registrable Securities. In connection
with any registration statement in which a holder of Registrable Securities is
participating, such holder will furnish to the Corporation in writing such
information and affidavits as the Corporation reasonably requests for use in
connection with any such registration statement or preliminary or final
prospectus or any amendment or supplement thereto or any document incorporated
by reference therein and shall indemnify and hold harmless the Corporation, its
employees, directors and officers, each Person who controls the Corporation
(within the meaning of the Securities Act and the Exchange Act) and all other
prospective sellers and their respective directors, officers and controlling
Persons (within the meaning of the Securities Act and the Exchange Act) against
any losses, claims, damages, liabilities and expenses (or actions in respect
thereof) arising out of or based upon any untrue or alleged untrue statement of
a material fact or any omission or alleged omission of a material fact required
to be stated in any registration statement or preliminary or final prospectus
relating to the registration of such Registrable Securities or any amendment
thereof or supplement thereto or necessary to make the statements therein, in
light of the circumstances in which they were made, not misleading, to the
extent, but only to the extent, that such untrue or alleged untrue statement or
omission or alleged omission is contained in any written information or
affidavit furnished by or on behalf of such holder specifically for use in such
registration statement or prospectus and then only to the extent of the total
proceeds received by such holder of Registrable Securities. Subject to the
provisions of Section 9(c), the

                                      -14-
<PAGE>   16

holders of Registrable Securities participating in any registration will
reimburse, to the extent of the total proceeds received by the holders of
Registrable Securities, the Corporation, its officers, directors and controlling
Persons and all other prospective sellers and their respective directors,
officers and controlling Persons for any reasonable legal and other expenses as
incurred in connection with investigation or defending any such losses, claims,
damages, liabilities, expenses or actions.

         (c) Conduct of Indemnification Proceedings. Any Person entitled to
indemnification hereunder will (i) give prompt notice to the indemnifying party
of any claim with respect to which it seeks indemnification (but omission of
such notice shall not relieve the indemnifying party from liability hereunder
except to the extent such indemnifying party is actually prejudiced by such
failure to give notice) and (ii) unless in such indemnified party's reasonable
judgment a conflict of interest may exist between such indemnified and
indemnifying parties with respect to such claim, permit such indemnifying party
to assume the defense of such claim with counsel reasonably satisfactory to the
indemnified party. The indemnifying party will not be subject to any liability
for any settlement made without its consent (but such consent will not be
unreasonably withheld or delayed). No indemnifying party will consent to entry
of any judgment or enter into any settlement which does not include as an
unconditional term thereof the giving by the claimant or plaintiff to such
indemnified party of an unconditional release from all liability in respect to
such claim or litigation and does not subject the indemnified party to any
material injunctive relief or other material equitable remedy. An indemnifying
party who is not entitled to, or elects not to, assume the defense of a claim
will not be obligated to pay the fees and expenses of more than one counsel for
all parties indemnified by such indemnifying party with respect to such claim.

         (d) Contribution. If the indemnification provided for in Section 9(a)
or Section 9(b) is unavailable or insufficient to hold harmless each of the
indemnified parties against any losses, claims, damages, liabilities and
expenses (or actions in respect thereof) to which such persons may become
subject under the Securities Act, then the indemnifying party shall, in lieu of
indemnifying each party entitled to indemnification hereunder, contribute to the
amount paid or payable by such party as a result of such losses, claims,
damages, liabilities or expenses in such proportion as is appropriate to reflect
the relative fault of the indemnifying party on the one hand and such
indemnified persons on the other in connection with the statements or omissions
or alleged statements or omissions that resulted in such losses, claims,
damages, liabilities or expenses. The relative fault of such persons shall be
determined by reference to, among other things, whether the untrue or alleged
untrue statement of a material fact, or omission or alleged omission to state a
material fact, relates to information supplied by or concerning the indemnifying
party on the one hand, or by such indemnified person on the other, and such
person's relative intent, knowledge, access to information and opportunity to
correct or prevent such statement or omission. The parties hereto agree that it
would not be just and equitable if contribution pursuant to this Section 9(d)
were determined by pro rata allocation or by any other allocation that does not
take into account the equitable considerations referred to in this Section 9(d).
The amount paid or payable by an indemnified party as a result of the losses,
claims, damages, liabilities or expenses referred to above shall be deemed to
include (subject to the limitations set forth in Section 9(b) or 9(c) hereof)
any legal or other fees or expenses reasonably incurred by such indemnified
party in connection with investigating or defending any such action, proceeding
or claim. No person guilty of fraudulent misrepresentation within the

                                      -15-
<PAGE>   17

meaning of the Act shall be entitled to contribution from any person that is not
guilty of such fraudulent misrepresentation.

         (e) Priority of Indemnification. Notwithstanding the foregoing, to the
extent that provisions on indemnification and contribution contained in the
underwriting agreement entered into in connection with an underwritten offering
are in conflict with the foregoing, the provisions of the underwriting agreement
shall prevail.

         (f) Payment. The indemnification and contribution required by this
Section 9 shall be made by periodic payments of the amount thereof during the
course of the investigation or defense, as and when bills are received or
expense, loss, damage or liability is incurred.

         (g) Beneficiaries of Indemnification. The obligations of the
Corporation and the holders of Registrable Securities under this Section 9 shall
be in addition to any liability that they may otherwise have.

10. RULE 144.

         The Corporation covenants that after the consummation of the IPO it
will use its reasonable best efforts to timely file the reports required to be
filed by it under the Securities Act and the Exchange Act and the rules and
regulations adopted by the SEC thereunder (or, if the Corporation is not
required to file such reports, it will, upon the request of any holder of
Registrable Securities, make publicly available such information), all to the
extent required from time to time to enable such holder to sell Registrable
Securities without registration under the Securities Act within the limitation
of the exemptions provided by (a) Rule 144 under the Securities Act, as such
Rule may be amended from time to time, or (b) any similar rule or regulation
hereafter adopted by the SEC. Upon the request of any holder of Registrable
Securities, the Corporation will deliver to such holder a written statement as
to whether it has complied with such requirements.

11. PARTICIPATION IN UNDERWRITTEN REGISTRATIONS; MARKET STAND-OFF AGREEMENT.

         (a) Participation in Underwritten Registration. No Person may
participate in any underwritten registration hereunder unless such Person (i)
agrees to sell such Person's securities on the basis provided in any
underwriting arrangements approved by the Persons entitled hereunder to approve
such arrangements and (ii) completes and executes all customary questionnaires,
powers of attorney, underwriting agreements, lock-ups and other documents
required under the terms of such underwriting arrangements.

         (b) Market Stand-Off Agreement. Each holder of Registrable Securities
agrees, whether or not it is participating in such registration statement, that
it shall not, to the extent requested by an underwriter of Common Stock (or
other securities of the Corporation), sell or otherwise transfer or dispose of
any securities of the Corporation (other than those included in the
registration) during the 90 day period following the effective date of a
registration statement of the Corporation filed under the Securities Act if such
holder owns or has the right to acquire 5% or more of the outstanding Common
Stock. In order to enforce the foregoing covenant, the Corporation may impose
stop-transfer instructions with respect to the securities of the Corporation
owned by holders of Registrable Securities until the end of such 90 day period.

<PAGE>   18

12. MISCELLANEOUS.

         (a) Right to Suspend. The Corporation may, by notice in writing to each
holder of Registrable Securities, require the holder of Registrable Securities
to suspend use of any prospectus included in a registration statement filed
hereunder if the Corporation reasonably determines that it contains an untrue
statement of a material fact or omits to state any material fact necessary to
make the statements therein not misleading or that any transaction in which the
Corporation is engaged or proposes to engage, or any event that has occurred or
is expected to occur, would require an amendment to such registration statement
or a supplement to such prospectus (including any such amendment or supplement
made through incorporation by reference to a report filed under Section 13 of
the Exchange Act). Each holder of Registrable Securities agrees that, upon
receipt of any notice from the Corporation of the happening of any event of the
kind described in this Section 12(a), such holder will forthwith discontinue
disposition of Registrable Securities pursuant to the registration statement
covering such Registrable Securities until such holder's receipt of the copies
of a properly supplemented or amended prospectus, and, if so directed by the
Corporation, such holder will deliver to the Corporation all copies, other than
permanent file copies, then in such holder's possession, of the most recent
prospectus covering such Registrable Securities at the time of receipt of such
notice. In the event the Corporation gives any such notice, the time period
mentioned in Section 7(a)(iii), if applicable, will be extended by the number of
days during the period from and including the date of the giving of such notice
to and including the date when each seller of Registrable Securities covered by
such registration statement has received the copies of such supplemented or
amended prospectus. The Corporation agrees to use its reasonable best efforts to
cause any suspension of use of any prospectus pursuant to this paragraph to be
as short a period of time as possible.

         (b) Remedies. No holder of Registrable Securities shall have any right
to take any action to restrain, enjoin or otherwise delay any registration as a
result of any controversy that might arise with respect to the interpretation or
implementation of this Agreement.

         (c) Amendments and Waivers. The provisions of this Agreement may not be
amended, modified or supplemented, and waivers or consents to departures from
the provisions hereof may not be given unless the Corporation has obtained the
written consent of (i) the holders of at least a Majority of the outstanding
Phillips Registrable Securities and (ii) the holders of at least a Majority of
the outstanding Duke Registrable Securities. Each holder of any Registrable
Securities at the time or thereafter shall be bound by any consent authorized by
this Section 12(c), whether or not such holder consented or whether or not such
Registrable Securities have been marked to indicate such consent.

         (d) Registrable Securities Held by the Corporation or its Subsidiaries.
Whenever the consent or approval of holders of all or any specified percentage
of Registrable Securities is required hereunder, Registrable Securities held by
the Corporation or any of its subsidiaries will not be counted in determining
whether such consent or approval was given by such holders.

         (e) Notices. All notices or other communications provided for hereunder
shall be in writing and shall be effective (i) on the day on which delivered if
delivered personally or transmitted by telex or telegram or telecopier with
evidence of receipt, (ii) one business day after

                                      -17-
<PAGE>   19

the date on which the same is delivered to a nationally recognized overnight
courier service with evidence of receipt, or (iii) three days after the date on
which the same is deposited, postage prepaid, in the U.S. mail, sent by
certified or registered mail, return receipt requested, and addressed to the
party to be notified at the address indicated below for the Corporation, or at
the address for the holder of the Registrable Securities set forth in a registry
maintained by the Corporation, or at such other address and/or telecopy or telex
number and/or to the attention of such other person as the Corporation or the
holder of the Registrable Securities may designate by ten-day advance written
notice.

         (f) Successors and Assigns; Transfer of Registration Rights. This
Agreement will inure to the benefit of and be binding upon the successors and
permitted assigns of each of the parties. The registration rights granted by
this Agreement may be transferred or assigned by operation of law or in
connection with any transfer or assignment of Registrable Securities (other than
in a transaction described in clause (i), (ii) or (iv) of Section 2) provided
that (x) upon such transfer or assignment the transferee or assignee holds
Registrable Securities equal to at least 10% of the then outstanding Common
Stock, (y) such transferee or assignee agrees in writing to be bound by the
terms of this Agreement and (z) the Corporation is given written notice of such
transfer or assignment within 10 days after such transfer or assignment, setting
forth the name and address of the transferee or assignee and identifying the
Registrable Securities with respect to which such registration rights have been
assigned. For purposes of exercise of requests pursuant to Section 3 or Section
4, transferees shall be included with Duke or Phillips, as the case may be,
based on who was the original transferor of such Registrable Securities.

         (g) Counterparts. This Agreement may be executed in one or more
counterparts and by the parties hereto in separate counterparts, all of which
will constitute one and the same agreement and shall become effective when one
or more counterparts have been signed by each of the parties hereto and
delivered (including by facsimile) to the other parties.

         (h) Headings. The headings in this Agreement are for convenience of
reference only and will not limit or otherwise affect the meaning hereof.

         (i) Governing Law; Jurisdiction. This Agreement will be governed by and
construed in accordance with the laws of the State of Delaware, without giving
effect to conflict of law principles. Any holder of Registrable Securities may
bring any action or proceeding to enforce or arising out of this Agreement or in
the instruments and agreements annexed hereto in any court of competent
jurisdiction.

         (j) Severability. In the event that any one or more of the provisions
contained herein, or the application thereof in any circumstance, is held
invalid, illegal or unenforceable, the validity, legality and enforceability of
any such provision in every other respect and of the remaining provisions
contained herein will not be affected or impaired thereby.

         (k) Termination of Registration Rights. The rights of any holder
hereunder to request registration or inclusion in any registration pursuant to
Section 4 or 5, respectively, with respect to any Duke Registrable Securities
shall terminate at such time as Duke and its Affiliates shall own less than 10%
of the outstanding common stock of the Corporation. The rights of any holder
hereunder to request registration or inclusion in any registration pursuant to
Section 3

                                      -18-
<PAGE>   20

or 5, respectively, with respect to any Phillips Registrable Securities shall
terminate at such time as Phillips and its Affiliates shall own less than 10% of
the outstanding common stock of the Corporation.

         (l) Entire Agreement. This Agreement is intended by the parties as a
final expression of their agreement and 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. There are no restrictions, promises,
warranties or undertakings, other than those set forth or referred to herein

to the Registrable Securities. This Agreement supersedes all prior agreements
and understandings between the parties with respect to such subject matter.
