       PART III(a).  COMPENSATION OF OFFICERS AND DIRECTORS

       1999 EXECUTIVE COMPENSATION PLAN

       COMPENSATION COMMITTEE OF THE BOARD OF DIRECTORS

       EXECUTIVE COMPENSATION REPORT TO THE STOCKHOLDERS

       GENERAL - Through the Compensation Committee (the "Committee") of the
       Corporation's Board of Directors, the Board of Directors has developed an
       aggressive "PAY FOR PERFORMANCE" executive compensation philosophy and
       programs to implement that philosophy. Effective since 1996, these
       programs combine to form the basis of the total compensation plan for
       senior management of the Corporation and its subsidiaries (the "Group"),
       which is designed to focus management's attention on the Corporation's
       strategic business initiatives and financial performance objectives. The
       Committee believes that the design and execution of the executive
       compensation program implemented in 1996 continue to be critical to the
       Corporation's future success by FOCUSING MANAGEMENT'S ATTENTION on the
       competitive business environment through compensation awards largely
       based on COLUMBIA VALUE ADDED ("CVA") FINANCIAL PERFORMANCE MEASURES and
       SHAREHOLDER RETURN. CVA performance measures determine the real value of
       a particular investment by the extent the return on that investment
       exceeds the cost of the investment, including the cost of capital.

       COMPENSATION PHILOSOPHY - The Board of Directors believes that total
       compensation is not only payment for services rendered to the Group, but
       also a means to provide a strong motivational vehicle for the achievement
       of key financial and strategic goals. The Group provides executives with
       the opportunity to increase their total compensation above base salary
       through annual and longer-term incentive compensation programs. Goals and
       objectives within the executive compensation program are established such
       that their achievement will result in added value to the Group over
       appropriate periods of time. This is how compensation is linked to
       corporate performance. To implement the pay for performance philosophy
       that the Group instituted in 1996, its executive compensation program is
       designed to:

              -PLACE AT RISK significant amounts of the executives' total
              compensation.

              -Base greater amounts of the executives' total compensation upon
              CREATING LONG-TERM VALUE FOR THE STOCKHOLDERS.

              -TIE COMPENSATION MORE CLOSELY TO THE FORTUNES OF THE STOCKHOLDERS
              through the use of a combination of cash and STOCK-BASED INCENTIVE
              COMPENSATION PLANS.

              -Emphasize the achievement of both short- and longer-term internal
              VALUE ADDED PERFORMANCE MEASURES as well as STOCKHOLDER RETURN
              EXPECTATIONS in relationship to peer companies.

              -Provide total compensation rewards to executives in relation to
              the overall financial performance of the Corporation.


                                                                              66
<PAGE>   68
       As a general matter, the executive compensation program is designed to
       provide base salary compensation levels that target the median of the
       marketplace in similar-sized energy and industrial companies; maintain
       equitable relationships among the compensation levels established for
       jobs within the Group; provide for the recognition of performance
       delivered year-to-year and over the long term; and ensure that
       appropriate controls are in place for compensation to be fully earned.
       Because of the Group's size and integrated nature, a number of well-known
       energy and general industry executive compensation surveys are utilized
       to determine competitive remuneration for executives. Most of the
       companies in the S&P Natural Gas Utility Index, which comprises the peer
       group are included in one or more of these surveys. However, no single
       authoritative executive compensation survey currently covers all of the
       companies in the S&P Natural Gas Utility Index. The Committee uses
       independent compensation consulting firms to assist it in determining the
       competitiveness of the Group's compensation plans and programs. In 1999
       two such firms, Hewitt Associates, LLC and Towers Perrin, were
       principally used.

      IMPLEMENTATION OF PHILOSOPHY - The Group's executive compensation program
      is administered by the Committee. The Committee is composed of six
      independent, nonemployee Directors. As of December 31, 1999, the Group's
      executive total compensation program consisted of the following:

              1. Base Salary Program

              2. Annual Incentive Compensation Plan

              3. Long-Term Incentive Plan

              4. Other Arrangements

      1. BASE SALARY PROGRAM - A base salary is established for each executive
      position based on a comparison of compensation levels of similar positions
      in the external market. Competitive base salary levels are needed to
      attract and retain competent executives. Based on the energy and general
      industry compensation surveys referred to above, the base salary levels
      for the approximately 190 individuals comprising the executive/key
      employee group presently approximate the median for similar groups with
      corporations of similar size and complexity. At the minimum opportunity
      levels for earning Annual Incentive Compensation Plan and Long-Term
      Incentive Plan awards, the executive compensation program is designed to
      deliver 40 to 54 percent of total compensation in the form of base pay,
      dependent upon the executive's level in the executive compensation
      program. At the maximum opportunity levels, base pay represents 28 to 43
      percent of an executive's compensation. In keeping with the philosophy of
      placing more compensation at risk and of targeting base salary at market
      levels, increases to base salary generally are made only in cases of
      promotions or marketplace equity adjustments, if individual performance
      warrants.

      2. ANNUAL INCENTIVE COMPENSATION PLAN - This plan, which was amended and
      re-implemented effective January 1, 1996, provides the opportunity for
      payment of cash awards to key employees generally for attainment of
      specific goals which contribute directly to the present and future
      financial health of the Group. Awards for 1999 performance, granted in
      2000 after financial results for 1999 were final, are reflected in the
      Summary Compensation Table and in the Executive Compensation Report
      subsection entitled "1999 Chief Executive Officer's Pay." The award
      opportunities for 1999 ranged from zero to 75 percent of an individual's
      annual base salary at target level performance, which generally depends
      upon the achievement of CVA financial goals and the individual's level of
      responsibility within the organization, along with an assessment of the
      individual's ability to contribute directly to the financial performance
      of the Group. Additional amounts can be awarded should financial
      performance exceed the target level and, in certain circumstances, should
      the individual exceed his or her personal performance goals. In limited
      circumstances, awards may be granted based on non-CVA goals, such as
      attainment of project milestones or personal performance goals.

      On February 22, 2000, in accordance with the Corporation's "pay for
      performance" philosophy, the Committee awarded cash awards to executives
      whose operating units met or exceeded the CVA goals, financial performance
      compared to peer companies, and/or specific 1999 individual employee
      performance objectives. Awards were granted at various levels. The average
      award represented 31 percent of the average base salary of all executives
      receiving Annual Incentive Compensation Plan awards, excluding Mr.
      Richard, the Chairman, President and CEO of the Corporation.


                                                                              67
<PAGE>   69
      3. LONG-TERM INCENTIVE PLAN - The executive compensation program also
      includes a component to bring special attention to the important area of
      stockholder return. The Long-Term Incentive Plan provides long-term
      incentives to officers and other key employees of Group companies through
      the granting of incentive stock options, non-qualified stock options,
      stock appreciation rights, contingent stock awards, restricted stock
      awards, and/or any award in other forms that the Committee may deem
      appropriate, consistent with the plan's purpose. For most option awards,
      the Corporation's Total Shareholder Return performance (stock price
      appreciation plus dividend accruals) has been compared to the peer group
      of companies included in the S&P Natural Gas Utility Index as included
      elsewhere in this report. For most option awards for 1999, the Committee
      provided awards as a result of the Corporation's Total Shareholder Return
      exceeding the third quartile Total Shareholder Return of the companies
      which comprise this peer group (excluding the Corporation). Dependent upon
      each employee's position, individual performance, and the Corporation's
      Total Shareholder Return, options for 3,000 to 40,000 shares may be
      awarded for performance at the third quartile (target, or above median),
      while options for 6,000 to 60,000 shares may be awarded for performance at
      the fourth quartile (stretch, or top quartile). Additional amounts can be
      awarded should an individual exceed his or her personal performance goals
      or if circumstances otherwise warrant. Option awards to key employees may
      be made for reasons other than Total Shareholder Return, subject to the
      discretion of the Committee. The purchase price per share of stock
      deliverable upon the exercise of a non-qualified stock option is 100
      percent of the fair market value of the stock on the date of grant. The
      price of options issued under the plan is credited with dividend
      equivalents. Such credits may be made directly through a reduction in the
      purchase price of stock subject to options. Alternatively, at the
      discretion of the Committee, dividend equivalent credits may be provided
      indirectly, for example through the establishment of an unsecured,
      unfunded bookkeeping "account" that would track dividends declared on the
      stock subject to options and that would be paid in cash to an optionee
      upon the exercise of an option or, in certain circumstances, upon
      expiration of the option. The amount of dividend equivalent credits may
      not exceed the option purchase price less par value. The Long-Term
      Incentive Plan was approved by the stockholders of the Corporation on
      April 26, 1996, and the plan became effective as of February 21, 1996. The
      plan was amended and restated on November 18, 1998, further amended on
      February 17, 1999, and approved by the Corporation's stockholders on May
      19, 1999. Awards made in 2000 for 1999 performance are reflected in the
      Options Table elsewhere in this report as well as the subsection of this
      report entitled "1999 Chief Executive Officer's Pay."

      On February 22, 2000, the Committee awarded options for 765,300 shares
      (excluding Mr. Richard) of the Corporation's stock in the form of
      non-qualified stock options for 1999 Total Shareholder Return performance
      at the target level, with individual performance bearing on the number
      delivered to employees. Key employees who were granted non-qualified stock
      options received an average of 4,373 shares.

      4. OTHER ARRANGEMENTS - Mr. Richard, Mr. Schwolsky, Senior Vice President
      and Chief Legal Officer of the Corporation, and Ms. Abbott, Chief
      Executive Officer and President of Columbia Gas Transmission Corporation
      and Chief Executive Officer of Columbia Gulf Transmission Company, were
      granted employment agreements upon hire. In addition, the Corporation has
      entered into change-in-control agreements with key executives, including
      Mr. O'Donnell, Senior Vice President and Chief Financial Officer of the
      Corporation, and Ms. Hammick, Senior Vice President of Columbia Energy
      Group Service Corporation. For a more detailed description of the
      agreements, please see "Employment Agreements" elsewhere in this report.

      DEDUCTIBILITY OF COMPENSATION - The Committee has reviewed the potential
      impact on the Group of Section 162(m) of the Internal Revenue Code, which
      imposes a limit on tax deductions that the Group may claim for annual
      compensation in excess of one million dollars paid to any of the CEO and
      the four other most highly compensated executive officers. The Committee
      has determined that under current compensation arrangements, the impact of
      Section 162(m) on the Group would be limited and, therefore, has decided
      not to take any action at this time to meet the requirements for a
      deduction.

      EVALUATION PROCESS - Each year, the Board of Directors of the Corporation
      reviews and approves strategic business and financial plans for the
      Corporation and each of its subsidiaries. In addition to various business
      strategies, these plans include specific financial goals such as CVA or
      other measures to evaluate whether stockholder value has increased. The
      goals set forth in these strategic plans are the bases for evaluating the
      performance of the CEO of the Corporation and other senior executives
      whose compensation falls under the direct purview of the Committee.
      Attainment of meaningful strategic goals over reasonable time periods
      increases value to stockholders, and the increased compensation
      opportunities for executives are directly linked to the attainment of
      these goals.


                                                                              68
<PAGE>   70
       1999 CHIEF EXECUTIVE OFFICER'S PAY

       BASE SALARY - When Mr. Richard was hired as CEO in 1995, the Corporation
       entered into an employment agreement with Mr. Richard that provides a
       base salary of $750,000 per year. The Board approved a marketplace
       adjustment for Mr. Richard in 1996 that increased his base salary to
       $787,500. As noted above, in keeping with the philosophy of placing more
       compensation at risk and of targeting base salary at market levels,
       increases to base salary for the executive group generally are made only
       in cases of promotions or marketplace equity adjustments. For those
       reasons, the Board approved no increases to Mr. Richard's base salary for
       1997, 1998 or 1999.

       ANNUAL INCENTIVE COMPENSATION - No Annual Incentive Compensation award
       was granted to Mr. Richard for 1999.

       LONG-TERM INCENTIVE PLAN - On May 20, 1996, Mr. Richard received a grant
       of 29,785 shares (44,677 post-stock split shares) of restricted stock
       under his amended employment agreement. To provide an additional
       incentive to Mr. Richard to continue his employment with the Corporation,
       the amended employment agreement provides that only 20 percent of such
       restricted stock vests each year; 60 percent is vested as of January 4,
       1999. On February 22, 2000, based on 1999 Total Shareholder Return
       performance at the target level and individual performance, the Committee
       awarded Mr. Richard, under the Long-Term Incentive Plan, a grant of
       non-qualified stock options to purchase 40,000 shares of common stock,
       with one-third vesting on the first anniversary of grant, one-third on
       the second anniversary of grant, and one-third on the third anniversary
       of grant. The effective date of the grant and pricing of the options is
       discussed in the "Long-Term Incentive Plan" subsection of the
       "Implementation of Philosophy" section of this report. The awards are
       included in the Options Table.

       EMPLOYMENT AGREEMENTS

       In order to secure the services of Mr. Richard, Mr. Schwolsky and Ms.
       Abbott, the Corporation has entered into employment agreements with each
       of these individuals. Set forth below is a brief description of the
       material terms of these agreements, as amended.

       Mr. Richard's agreement was entered into in 1995 and was amended in 1996
       and again in 1999. As amended, Mr. Richard's agreement provides for a
       three year term, with automatic annual extensions (unless either party to
       the agreement gives notice that the agreement shall not be extended), and
       provides that he will serve as the Chairman, President and Chief
       Executive Officer of the Corporation. In addition to salary, short- and
       long-term incentive compensation (as previously discussed in this report
       in the Executive Compensation Report of the Compensation Committee), and
       other fringe benefits, Mr. Richard's agreement provides for severance
       benefits if his employment is terminated under various scenarios. For
       example, if Mr. Richard's employment is terminated by the Corporation for
       a reason other than cause, death or disability, if Mr. Richard terminates
       his employment because the Corporation has removed him from his current
       position or has reduced his duties or if the Corporation prevents the
       term of the agreement from automatically extending, Mr. Richard will
       receive severance benefits. Such severance benefits would include a
       payment of salary and annual incentive for 24 months, a supplemental
       retirement benefit, and fringe benefits. If Mr. Richard terminates his
       employment for various reasons following a change in control (as defined
       in the agreement), he would be entitled to enhanced severance benefits.
       Such severance benefits would include a payment equal to three times his
       annual salary and annual incentive, a prorated bonus for the year of
       termination, supplemental retirement plan benefits including an amount
       equal to the contributions that would have been contributed under certain
       retirement plans to which the Corporation contributes, vesting of stock
       options and restricted stock, continuation of health, welfare and fringe
       benefits for three years and other perquisites. In addition, if a
       "parachute payment" excise tax is triggered under the Internal Revenue
       Code, the Corporation will provide a gross-up payment to Mr. Richard.

       Mr. Schwolsky's employment agreement was entered into in 1995 and was
       amended in 1999. As amended, Mr. Schwolsky's agreement provides for a
       three-year term, with automatic annual extensions (unless either party to
       the agreement gives notice that the agreement shall not be extended), and
       provides that he will serve as the Senior Vice President and Chief Legal
       Officer of the Corporation. In addition to stock-based grants made in
       1995, the agreement provides an annual base salary of $285,000, subject
       to such increases as may be approved by the Board. Besides being eligible
       to participate in all incentive compensation plans and employee benefit
       programs provided to other senior executives of the Group, the agreement
       provides severance benefits substantially the same as those provided to
       Mr. Richard, as described in the preceding paragraph, but based on Mr.
       Schwolsky's levels of compensation and benefits.


                                                                              69
<PAGE>   71
       Ms. Abbott's employment agreement was entered into in 1996 and was
       amended in 1999. As amended, Ms. Abbott's agreement provides for a
       three-year term, with automatic annual extensions (unless either party to
       the agreement gives notice that the agreement shall not be extended), and
       provides that she will serve as the Chief Executive Officer of the
       Corporation's transmission subsidiaries. In addition to a grant of stock
       made in 1996, the agreement provides for an annual base salary of
       $325,000, subject to such increases as may be approved by the Board. The
       agreement also provides that Ms. Abbott is eligible to participate in all
       employee benefit programs provided to other transmission company
       executives and in all incentive compensation programs of the transmission
       companies appropriate for her status. The agreement further provides
       severance benefits substantially the same as those provided to Mr.
       Richard and Mr. Schwolsky, as described above, but based on Ms. Abbott's
       levels of compensation and benefits.

       In addition, in order to retain the services of Mr. O'Donnell and Ms.
       Hammick, the Corporation has entered into change-in-control agreements
       with these individuals. Generally, the agreements provide these
       individuals with benefits similar to those provided to Messrs. Richard
       and Schwolsky and Ms. Abbott in the event of an employment termination
       following a change in control, except that benefits under Mr. O'Donnell's
       and Ms. Hammick's agreements do not become payable by the Corporation
       upon a voluntary termination (or termination without "good reason") of
       employment after the occurrence of a change in control.


                                                                              70

RETIREMENT INCOME PLAN

A non-contributory defined benefit plan is maintained for all eligible employees
of the Corporation's participating subsidiaries. The Plan consists of two
options: a final average pay option and (as of January 1, 2000) as account
balance option. Eligible participants in the plan will be offered a one-time
election to remain in the final average pay option or switch to the account
balance option. Employees will make their election between March 15, 2000 and
April 30, 2000. Eligible employees hired on or after January 1, 2000 will
automatically be enrolled in the account balance option.



The annual benefit under the final average pay option is based upon final
average annual compensation and years of credited service. Final average annual
compensation is calculated using base compensation (shown in the "Summary
Compensation Table" as "Salary") paid to the employee for the highest 36 months
of the last 60 months prior to retirement.



Estimated annual benefits payable under the final average pay option upon
retirement are as follows with respect to the specified remuneration and years
of credited service.

  *  Estimates are based upon a straight-life annuity and the assumptions that
     (a) the final average pay option of the Corporation's present retirement
     plan will be maintained and (b) retirement will not occur before age 65.
     These benefits are not subject to deduction for social security or other
     charges. Should an annual benefit exceed limitations imposed by federal
     law, the excess will be paid by the participating subsidiary as a
     supplemental pension under the Pension Restoration Plan. Such supplemental
     pensions are not available to these executives until retirement or
     termination of employment.

  ** As of January 1, 2000, the credited years of service for retirement
     benefits for the individuals named in the Summary Compensation Table were
     as follows: Mr. Richard, 8 years; Mr. O'Donnell, 29 years; Mr. Schwolsky, 8
     years; Ms. Abbott, 4 years; and Ms. Hammick, 2 years.

  *  The nonemployee Directors are also eligible to receive non-qualified stock
     options pursuant to the Corporation's Long-Term Incentive Plan. If the
     Corporation's Total Shareholder Return performance, compared with its
     peers, is at the third quartile (above median), then nonemployee Directors
     receive options for 3,000 shares of common stock; at the fourth (top)
     quartile, options for 6,000 shares. If Total Shareholder Return performance
     is at or below the median, then the nonemployee Directors receive no
     options. The options vest one-third upon grant, one-third one year after
     grant, and one-third two years after grant, and they have a ten-year term.
     For 1999 performance, the Directors will receive options for 3,000 shares,
     granted and priced as of February 22, 2000, at a purchase price of $58.9375
     per share of common stock. See the section entitled "1999 Executive
     Compensation Plan" for a discussion of the terms of the option grants.

  ** Lead Director's retainer.

No officer received any compensation for services as a Director while also
serving as an officer of the Corporation.

The Corporation offers medical coverage to current nonemployee Directors and
pays the premium associated with their participation. The Corporation also
reimburses them for the cost of Medicare Part B, if applicable. In addition,
nonemployee Directors may elect to defer compensation for distribution at a
later date. Deferred amounts will accrue interest at the prime rate under the
Deferred Compensation Plan for Outside Directors or may be deferred into the
Phanton Stock Plan for Outside Directors. Deferrals may be paid in a lump sum or
in installments but will be automatically paid in a lump sum under the Deferred
Compensation Plan for Outside Directors following certain specified changes in
control of the Corporation.

Following its approval by the stockholders at the 1996 Annual Meeting, the
Phantom Stock Plan for Outside Directors was established. All of the Directors
except two (one of whom has since retired) elected to participate in the plan in
lieu of participating in the Retirement Plan for Outside Directors.
Participating directors received phantom shares of equivalent actuarial value
under the Phantom Stock Plan for Outside Directors. The Retirement Plan for
Outside Directors is not available for nonemployee Directors assuming office
after April 1996; rather, they participate in the Phantom Stock Plan for Outside
Directors, under which they receive 3,000 phantom shares upon being elected to
the Board. Payment of cash benefits will commence upon termination of Board
service.

For the Director(s) remaining in the Retirement Plan, each nonemployee Director
with a minimum of five years' service on the Board who retires after attaining
age 65 or becoming disabled could receive annual retirement payments equal to
the amount of the annual retainer for Board service at the time of retirement.
Payments under the Retirement Plan will cease at the death of the Director
unless the Director elected an actuarial equivalent option or, if death occurs
before retirement but after eligibility is established, at the death of the
surviving spouse. In the event of certain specified changes in control of the
Corporation, a Director (regardless of years of service on the Board) could
elect a lump sum payment equal to the present value of the retainer at the time
of the election times the number of years of Board service, with a minimum of
ten years.

The director's compensation amounted to $1,092,000.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS


To the Shareholders of Columbia Energy Group:

We have audited the consolidated balance sheets of Columbia Energy Group (a
Delaware corporation, the "Corporation") and subsidiaries as of December 31,
1999 and 1998, and the related statements of consolidated income, cash flows and
common stock equity for each of the three years in the period ended December 31,
1999. These financial statements are the responsibility of the Corporation's
management. Our responsibility is to express an opinion on these financial
statements based on our audits.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in
all material respects, the financial position of the Corporation and
subsidiaries as of December 31, 1999 and 1998, and the results of their
operations and their cash flows for each of the three years in the period ended
December 31, 1999, in conformity with generally accepted accounting principles.

of Directors.
<PAGE>   43
                                                                   Exhibit 17-A

         (b) Subject to the applicable provisions of the by-laws then in effect,
to determine, from time to time, whether and to what extent and at what times
and places and under what conditions and regulations the accounts and books and
documents of the Corporation, or any of them, shall be opened to the inspection
of the stockholders, and no stockholder shall have any right to inspect any
account or book or document of the Corporation, except as conferred by statute,
unless and until authorized so to do by resolution of the Board of Directors or
of the stockholders of the Corporation.

         (c) To authorize and cause to be executed mortgages and liens upon the
real and personal property of the Corporation.

         (d) To determine whether any, and, if any, what part, of the net
profits of the Corporation or of its surplus shall be declared in dividends and
paid to the stockholders, and to direct and determine the use and disposition of
any such net profits or such net assets in excess of capital.

         (e) To set apart out of any funds of the Corporation available for
dividends a reserve or reserves for any proper purpose and to abolish any such
reserve or reserves, to make such other provisions, if any, as the Board of
Directors may deem necessary or advisable for working capital, for additions,

business of the Corporation (including the acquisition of real and personal
property for that purpose) and for any other purposes of the Corporation.

         (f) By resolution or resolutions passed by a majority of the whole
Board, to designate one or more committees, each committee to consist of two or
more of the directors of the Corporation. The Board may designate one or more
directors as alternate members of any committee, who may replace any absent or

at the meeting in the place of any such absent or disqualified member.

         (g) When and as authorized by the affirmative vote of the holders of a
majority of the stock issued and outstanding having voting power given at a
stockholders' meeting duly called upon such notice as is required by statute, or
when authorized by the written consent of the holders of a majority of the
voting stock issued and outstanding, to sell, lease, or exchange all or
substantially all of the property and assets of the Corporation, including its

such consideration, which may consist in whole or in part of money or property
including shares of stock in, and/or other securities of, any other corporation
or corporations, as its Board of Directors shall deem expedient and for the best
interests of the Corporation.

         (h) The Corporation may in its by-laws confer powers upon its Board of
Directors in addition to the foregoing and in addition to the powers and
authorities expressly conferred upon it by statute.

                                                                   Exhibit 17-A
                                                                    Page 3 of 7


         NINTH. To the fullest extent that the General Corporation Law of the
State of Delaware as it exists on the date hereof or as it may hereafter be
amended permits the limitation or elimination of the liability of directors, no
director of the Corporation shall be liable to the Corporation or its
stockholders for monetary damages for breach of fiduciary duty as a director. No
amendment to or repeal of this Paragraph 9 shall apply to or have any effect on
the liability of any director of the Corporation for or with respect to any acts
or omissions of such director occurring prior to such amendment or repeal.

         TENTH. (a) Right to Indemnification. The Corporation shall to the
fullest extent permitted by applicable law as then in effect indemnify any
person (the "Indemnitee") who was or is involved in any manner (including,
without limitation, as a party or a witness) or is threatened to be made so
involved in any threatened, pending or completed investigation, claim, action,
suit or proceeding, whether civil, criminal, administrative or investigative
(including without limitation, any action, suit or proceeding by or in the right
of the Corporation to procure a judgment in its favor) (a "Proceeding") by
reason of the fact that such person is or was a director, officer, employee or
agent of the Corporation, or is or was serving at the request of the Corporation
as a director, officer, employee or agent of another corporation, partnership,
joint venture, trust or other enterprise (including, without limitation, any
employee benefit plan) against all expenses (including attorneys' fees),
judgments, fines and amounts paid in settlement actually and reasonably incurred
by such person in connection with such Proceeding. Such indemnification shall be
a contract right and shall include the right to receive payment of any expenses
incurred by the Indemnitee in connection with such Proceeding in advance of its
final disposition, consistent with the provisions of applicable law as then in
effect.

         (b) Insurance, Contracts and Funding. The Corporation may purchase and
maintain insurance to protect itself and any Indemnitee against any expenses,
judgments, fines and amounts paid in settlement as specified in Section (a) of
this Paragraph 10 or incurred by an Indemnitee in connection with any proceeding
referred to in Section (a) of this Paragraph 10, to the fullest extent permitted
by applicable law as then in effect. The Corporation may enter into contracts
with any director, officer, employee or agent of the Corporation in furtherance
of the provisions of this Paragraph 10 and may create a trust fund, grant a
security interest or use other means (including, without limitation, a letter of
credit) to ensure the payment of such amounts as may be necessary to effect
indemnification as provided in this Paragraph 10.

         (c) Indemnification; Not Exclusive Right. The right of indemnification
provided in this Paragraph 10 shall not be exclusive of any other rights to
which those seeking indemnification may otherwise be entitled, and the
provisions of this Paragraph 10 shall inure to the benefit of the heirs and
legal representatives of any person entitled to indemnity under this Paragraph
10 and shall be applicable to Proceedings commenced or continuing after the
adoption of this Paragraph 10, whether arising from acts or omissions occurring
before or after such adoption.

         (d) Advancement of Expenses; Procedures; Presumptions and Effect of
Certain Proceedings; Remedies. In furtherance, but not in limitation of the
foregoing provisions, the following procedures, presumptions and remedies shall
apply with respect to advancement of expenses and the right to indemnification
under this Paragraph 10:

         (1) Advance of Expenses. All reasonable expenses incurred by or on
behalf of the Indemnitee in connection with any Proceeding shall be advanced to
the Indemnitee by the Corporation within 20 days after the receipt by the
Corporation of a statement or statements from the Indemnitee requesting such
advance or advances from time to time, whether prior to or after
<PAGE>   45
                                                                   Exhibit 17-A
                                                                    Page 4 of 7


final disposition of such Proceeding. Such statement or statements shall
reasonably evidence the expenses incurred by the Indemnitee and, if required by
law at the time of such advance, shall include or be accompanied by an
undertaking by, or on behalf of, the Indemnitee to repay the amounts advanced if
it should ultimately be determined that the Indemnitee is not entitled to be
indemnified against such expenses pursuant to this Paragraph 10.

         (2) Procedure for Determination of Entitlement to Indemnification. (i)
To obtain indemnification under this Paragraph 10, an Indemnitee shall submit to
the Secretary of the Corporation a written request including such documentation
and information as is reasonably available to the Indemnitee and reasonably
necessary to determine whether and to what extent the Indemnitee is entitled to
indemnification (the "Supporting Documentation"). The determination of the
Indemnitee's entitlement to indemnification shall be made not later than 60 days
after receipt by the Corporation of the written request for indemnification
together with Supporting Documentation. The Secretary of the Corporation shall,
promptly upon receipt of such a request for indemnification, advise the Board of
Directors in writing the Indemnitee has requested indemnification.

         (ii) The Indemnitee's entitlement to indemnification under this
Paragraph 10 shall be determined in one of the following ways: (A) by a majority
vote of the Disinterested Directors (as hereinafter defined), if they constitute
a quorum of the Board of Directors; (B) by a written opinion of Independent
Counsel (as hereinafter defined) if (x) a Change of Control (as hereinafter
defined) shall have occurred and the Indemnitee so requests or (y) a quorum of
the Board of Directors consisting of Disinterested Directors is not obtainable
or, even if obtainable, a majority of such Disinterested Directors so directs;
(C) by the stockholders of the Corporation (but only if a majority of the
Disinterested Directors, if they constitute a quorum of the Board of Directors,
present the issue of entitlement to indemnification to the stockholders for
their determination); or (D) as provided in Section (d)(3).

         (iii) In the event the determination of entitlement to indemnification
is to be made by Independent Counsel pursuant to Section (d)(2)(ii), a majority
of the Disinterested Directors shall select the Independent Counsel, but only an
Independent Counsel to which the Indemnitee does not reasonably object;
provided, however, that if a Change of Control shall have occurred, the
Indemnitee shall select such Independent Counsel, but only an Independent
Counsel to which the Board of Directors does not reasonably object.

         (iv) The only basis upon which a finding of no entitlement to
indemnification may be made is that indemnification is prohibited by law.

         (3) Presumptions and Effect of Certain Proceedings. Except as otherwise
expressly provided in this Paragraph 10, if a Change of Control shall have
occurred, the Indemnitee shall be presumed to be entitled to indemnification
under this Paragraph 10 upon submission of a request for indemnification
together with the Supporting Documentation in accordance with Section (d)(2)(i),
and thereafter the Corporation shall have the burden of proof to overcome that
presumption in reaching a contrary determination. In any event, if the person or
persons empowered under Section (d)(2) to determine entitlement to
indemnification shall not have been appointed or shall not have made a
determination within 60 days after receipt by the Corporation of the request
therefor together with the Supporting Documentation, the Indemnitee shall be
deemed to be entitled to indemnification and the Indemnitee shall be entitled to
such indemnification unless (A) the Indemnitee misrepresented or failed to
disclose a material fact in
<PAGE>   46
                                                                   Exhibit 17-A
                                                                    Page 5 of 7


making the request for indemnification or in the Supporting Documentation or (B)
such indemnification is prohibited by law. The termination of any Proceeding
described in Section (a), or of any claim, issue or matter therein, by judgment,
order settlement or conviction, or upon a pleas of nolo contendere or its
equivalent, shall not, of itself, adversely affect the right of the Indemnitee
to indemnification or create a presumption that the Indemnitee did not act in
good faith and in a manner which the Indemnitee reasonably believed to be in or
not opposed to the best interests of the Corporation or, with respect to any
criminal Proceeding, that the Indemnitee had reasonable cause to believe that
the Indemnitee's conduct was unlawful.

         (4) Remedies of Indemnitee.

         (i) In the event that a determination is made pursuant to Section
(d)(2) or (3), that the Indemnitee is not entitled to indemnification under this
Paragraph 10, (A) the Indemnitee shall be entitled to seek an adjudication of
his entitlement to such indemnification either, at the Indemnitee's sole option,
in (x) an appropriate court of the State of Delaware or any other court of
competent jurisdiction or (y) an arbitration to be conducted by a single
arbitrator pursuant to the rules of the American Arbitration Association; (B)
any such judicial proceeding or arbitration shall be de novo and the Indemnitee
shall not be prejudiced by reason of such adverse determination; and (C) in any
such judicial proceeding or arbitration the Corporation shall have the burden of
proving that the Indemnitee is not entitled to indemnification under this
Paragraph 10.

         (ii) If a determination shall have been made or deemed to have been
made, pursuant to Section (d)(2) or (3), that the Indemnitee is entitled to
Indemnitee, the Corporation shall be obligated to pay the amounts constituting
such indemnification within five days after such determination has been made or
deemed to have been made and shall be conclusively bound by such determination
unless (A) the Indemnitee misrepresented or failed to disclose a material fact
in making the request for indemnification or in the Supporting Documentation or
(B) such indemnification or in the Supporting Documentation or (C) such
indemnification is prohibited by law. In the event that (x) advancement of
expenses if not timely made pursuant to Section (d)(l) or (y) payment of
indemnification is not made within five days after a determination of
entitlement to indemnification has been made or deemed to have been made
pursuant to Section (d)(2) or (3), the Indemnitee shall be entitled to seek
judicial enforcement of the Corporation's obligation to pay to the Indemnitee
such advancement of expenses or indemnification. Notwithstanding the foregoing,
the Corporation may bring an action, in an appropriate court in the State of
Delaware or any other court of competent jurisdiction, contesting the right of
the Indemnitee to receive indemnification hereunder due to the occurrence of an
event described in subclause (A) or (B) of this clause (ii) (a "Disqualifying
Event"); provided, however, that in any such action the Corporation shall have
the burden of proving the occurrence of such Disqualifying Event.

         (iii) The Corporation shall be precluded from asserting in any judicial
proceeding or arbitration commenced pursuant to this Section (d)(4) that the
procedures and presumptions of this Paragraph 10 are not valid, binding and
enforceable and shall stipulate in any such court or before any such arbitrator
that the Corporation is bound by all the provisions of this Paragraph 10.

         (iv) In the event that the Indemnitee, pursuant to this Section (d)(4),
seeks a judicial adjudication of or an award in arbitration to enforce his
rights under, or to recover damages for breach of, this Paragraph 10, the
Indemnitee shall be entitled to recover from the Corporation,
<PAGE>   47
                                                                   Exhibit 17-A
                                                                    Page 6 of 7


and shall be indemnified by the Corporation against, any expenses actually and
reasonably incurred by the Indemnitee if the Indemnitee prevails in such
judicial adjudication or arbitration. If it shall be determined in such judicial
adjudication or arbitration that the Indemnitee is entitled to receive part but
not all of the indemnification or advancement of expenses sought, the expenses
incurred by the Indemnitee in connection with such judicial adjudication or
arbitration shall be prorated accordingly.

          (5) Definitions. For purposes of this Section (d):

         (i) "Change in Control" means (A) so long as the Public Utility Holding
Company Act of 1935 is in effect, any "company" becoming a "holding company" in
respect to the Corporation or any determination, by the Securities and Exchange
Commission that any "person" should be subject to the obligations, duties, and

<PAGE>   58
                                                                    Exhibit 20-A
                                                                     Page 2 of 7

     (b) Subject to the applicable provisions of the by-laws then in effect, to
determine, from time to time, whether and to what extent and at what times and
places and under what conditions and regulations the accounts and books and
documents of the Corporation, or any of them, shall be opened to the inspection
of the stockholders, and no stockholder shall have any right to inspect any
account or book or document of the Corporation, except as conferred by statute,
unless and until authorized so to do by resolution of the Board of Directors or
of the stockholders of the Corporation.

     (c) To authorize and cause to be executed mortgages and liens upon the real
and personal property of the Corporation.

     (d) To determine whether any, and, if any, what part, of the net profits of

     (e) To set apart out of any funds of the Corporation available for

property for that purpose) and for any other purposes of the Corporation.

     (f) By resolution or resolutions passed by a majority of the whole Board,

have and may exercise the powers of the Board of Directors in the management of
the business and affairs of the Corporation, and may authorize the seal of the
Corporation to be affixed to all papers which may require it; provided, however,
the by-laws may provide that in the absence of disqualification of any member of
such committee or committees, the member or members thereof present at any

quorum, may unanimously appoint another member of the Board of Directors to act
at the meeting in the place of any such absent or disqualified member.

     (g) When and as authorized by the affirmative vote of the holders of a
majority of the stock issued and outstanding having voting power given at a
stockholders' meeting duly called upon such notice as is required by statute, or
when authorized by the written consent of the holders of a majority of the
voting stock issued and outstanding, to sell, lease, or exchange all or
substantially all of the property and assets of the Corporation, including its
good will and its corporate franchises, upon such terms and conditions and for
such consideration, which may consist in whole or in part of money or property
including shares of stock in, and/or other securities of, any other corporation
or corporations, as its Board of Directors shall deem expedient and for the best
interests of the Corporation.

     (h) The Corporation may in its by-laws confer powers upon its Board of
Directors in addition to the foregoing and in addition to the powers and
authorities expressly conferred upon
<PAGE>   59
                                                                    Exhibit 20-A
                                                                     Page 3 of 7
it by statute.

     NINTH. To the fullest extent that the General Corporation Law of the State
of Delaware as it exists on the date hereof or as it may hereafter be amended
permits the limitation or elimination of the liability of directors, no director
of the Corporation shall be liable to the Corporation or its stockholders for
monetary damages for breach of fiduciary duty as a director. No amendment to or
repeal of this Paragraph 9 shall apply to or have any effect on the liability of
any director of the Corporation for or with respect to any acts or omissions of
such director occurring prior to such amendment or repeal.

     TENTH. (a) Right to Indemnification. The Corporation shall to the fullest
extent permitted by applicable law as then in effect indemnify any person (the
"Indemnitee") who was or is involved in any manner (including, without
limitation, as a party or a witness) or is threatened to be made so involved in
any threatened, pending or completed investigation, claim, action, suit or
proceeding, whether civil, criminal, administrative or investigative (including
without limitation, any action, suit or proceeding by or in the right of the
Corporation to procure a judgment in its favor) (a "Proceeding") by reason of
the fact that such person is or was a director, officer, employee or agent of
the Corporation, or is or was serving at the request of the Corporation as a
director, officer, employee or agent of another corporation, partnership, joint
venture, trust or other enterprise (including, without limitation, any employee
benefit plan) against all expenses (including attorneys' fees), judgments, fines
and amounts paid in settlement actually and reasonably incurred by such person
in connection with such Proceeding. Such indemnification shall be a contract
right and shall include the right to receive payment of any expenses incurred by
the Indemnitee in connection with such Proceeding in advance of its final
disposition, consistent with the provisions of applicable law as then in effect.

     (b) Insurance, Contracts and Funding. The Corporation may purchase and
maintain insurance to protect itself and any Indemnitee against any expenses,
judgments, fines and amounts paid in settlement as specified in Section (a) of
this Paragraph 10 or incurred by an Indemnitee in connection with any proceeding
referred to in Section (a) of this Paragraph 10, to the fullest extent permitted
by applicable law as then in effect. The Corporation may enter into contracts
with any director, officer, employee or agent of the Corporation in furtherance
of the provisions of this Paragraph 10 and may create a trust fund, grant a
security interest or use other means (including, without limitation, a letter of
credit) to ensure the payment of such amounts as may be necessary to effect
indemnification as provided in this Paragraph 10.

     (c) Indemnification; Not Exclusive Right. The right of indemnification
provided in this Paragraph 10 shall not be exclusive of any other rights to
which those seeking indemnification may otherwise be entitled, and the
provisions of this Paragraph 10 shall inure to the benefit of the heirs and
legal representatives of any person entitled to indemnity under this Paragraph
10 and shall be applicable to Proceedings commenced or continuing after the
adoption of this Paragraph 10, whether arising from acts or omissions occurring
before or after such adoption.

     (d) Advancement of Expenses; Procedures; Presumptions and Effect of Certain
Proceedings; Remedies. In furtherance, but not in limitation of the foregoing
provisions, the following procedures, presumptions and remedies shall apply with
respect to advancement of expenses and the right to indemnification under this
Paragraph 10:
<PAGE>   60
                                                                    Exhibit 20-A
                                                                     Page 4 of 7


     (1) Advance of Expenses. All reasonable expenses incurred by or on behalf
of the Indemnitee in connection with any Proceeding shall be advanced to the
Indemnitee by the Corporation within 20 days after the receipt by the
Corporation of a statement or statements from the Indemnitee requesting such
advance or advances from time to time, whether prior to or after final
disposition of such Proceeding. Such statement or statements shall reasonably
evidence the expenses incurred by the Indemnitee and, if required by law at the
time of such advance, shall include or be accompanied by an undertaking by, or
on behalf of, the Indemnitee to repay the amounts advanced if it should
ultimately be determined that the Indemnitee is not entitled to be indemnified
against such expenses pursuant to this Paragraph 10.

     (2) Procedure for Determination of Entitlement to Indemnification. (i) To
obtain indemnification under this Paragraph 10, an Indemnitee shall submit to
the Secretary of the Corporation a written request including such documentation
and information as is reasonably available to the Indemnitee and reasonably
necessary to determine whether and to what extent the Indemnitee is entitled to
indemnification (the "Supporting Documentation"). The determination of the
Indemnitee's entitlement to indemnification shall be made not later than 60 days
after receipt by the Corporation of the written request for indemnification
together with Supporting Documentation. The Secretary of the Corporation shall,
promptly upon receipt of such a request for indemnification, advise the Board of
Directors in writing the Indemnitee has requested indemnification.

     (ii) The Indemnitee's entitlement to indemnification under this Paragraph
10 shall be determined in one of the following ways: (A) by a majority vote of
the Disinterested Directors (as hereinafter defined), if they constitute a
quorum of the Board of Directors; (B) by a written opinion of Independent
Counsel (as hereinafter defined) if (x) a Change of Control (as hereinafter
defined) shall have occurred and the Indemnitee so requests or (y) a quorum of
the Board of Directors consisting of Disinterested Directors is not obtainable
or, even if obtainable, a majority of such Disinterested Directors so directs;
(C) by the stockholders of the Corporation (but only if a majority of the
Disinterested Directors, if they constitute a quorum of the Board of Directors,
present the issue of entitlement to indemnification to the stockholders for
their determination); or (D) as provided in Section (d)(3).

     (iii) In the event the determination of entitlement to indemnification is
to be made by Independent Counsel pursuant to Section (d)(2)(ii), a majority of
the Disinterested Directors shall select the Independent Counsel, but only an
Independent Counsel to which the Indemnitee does not reasonably object;
provided, however, that if a Change of Control shall have occurred, the
Indemnitee shall select such Independent Counsel, but only an Independent
Counsel to which the Board of Directors does not reasonably object.

     (iv) The only basis upon which a finding of no entitlement to
indemnification may be made is that indemnification is prohibited by law.

     (3) Presumptions and Effect of Certain Proceedings. Except as otherwise
expressly provided in this Paragraph 10, if a Change of Control shall have
occurred, the Indemnitee shall be presumed to be entitled to indemnification
under this Paragraph 10 upon submission of a request for indemnification
together with the Supporting Documentation in accordance with Section (d)(2)(i),
and thereafter the Corporation shall have the burden of proof to overcome that
presumption in reaching a contrary determination. In any event, if the person or
persons
<PAGE>   61
                                                                    Exhibit 20-A
                                                                     Page 5 of 7


empowered under Section (d)(2) to determine entitlement to indemnification shall
not have been appointed or shall not have made a determination within 60 days
after receipt by the Corporation of the request therefor together with the
Supporting Documentation, the Indemnitee shall be deemed to be entitled to
indemnification and the Indemnitee shall be entitled to such indemnification
unless (A) the Indemnitee misrepresented or failed to disclose a material fact
in making the request for indemnification or in the Supporting Documentation or
(B) such indemnification is prohibited by law. The termination of any Proceeding
described in Section (a), or of any claim, issue or matter therein, by judgment,
order settlement or conviction, or upon a pleas of nolo contendere or its
equivalent, shall not, of itself, adversely affect the right of the Indemnitee
to indemnification or create a presumption that the Indemnitee did not act in
good faith and in a manner which the Indemnitee reasonably believed to be in or
not opposed to the best interests of the Corporation or, with respect to any
criminal Proceeding, that the Indemnitee had reasonable cause to believe that
the Indemnitee's conduct was unlawful.

     (4) Remedies of Indemnitee.

     (i) In the event that a determination is made pursuant to Section (d)(2) or
(3), that the Indemnitee is not entitled to indemnification under this Paragraph
10, (A) the Indemnitee shall be entitled to seek an adjudication of his
entitlement to such indemnification either, at the Indemnitee's sole option, in
(x) an appropriate court of the State of Delaware or any other court of
competent jurisdiction or (y) an arbitration to be conducted by a single
arbitrator pursuant to the rules of the American Arbitration Association; (B)
any such judicial proceeding or arbitration shall be de novo and the Indemnitee
shall not be prejudiced by reason of such adverse determination; and (C) in any
such judicial proceeding or arbitration the Corporation shall have the burden of
proving that the Indemnitee is not entitled to indemnification under this
Paragraph 10.

     (ii) If a determination shall have been made or deemed to have been made,
pursuant to Section (d)(2) or (3), that the Indemnitee is entitled to
Indemnitee, the Corporation shall be obligated to pay the amounts constituting
such indemnification within five days after such determination has been made or
deemed to have been made and shall be conclusively bound by such determination
unless (A) the Indemnitee misrepresented or failed to disclose a material fact
in making the request for indemnification or in the Supporting Documentation or
(B) such indemnification or in the Supporting Documentation or (C) such
indemnification is prohibited by law. In the event that (x) advancement of
expenses if not timely made pursuant to Section (d)(l) or (y) payment of
indemnification is not made within five days after a determination of
entitlement to indemnification has been made or deemed to have been made
pursuant to Section (d)(2) or (3), the Indemnitee shall be entitled to seek
judicial enforcement of the Corporation's obligation to pay to the Indemnitee
such advancement of expenses or indemnification. Notwithstanding the foregoing,
the Corporation may bring an action, in an appropriate court in the State of
Delaware or any other court of competent jurisdiction, contesting the right of
the Indemnitee to receive indemnification hereunder due to the occurrence of an
event described in subclause (A) or (B) of this clause (ii) (a "Disqualifying
Event"); provided, however, that in any such action the Corporation shall have
the burden of proving the occurrence of such Disqualifying Event.

     (iii) The Corporation shall be precluded from asserting in any judicial
proceeding or arbitration commenced pursuant to this Section (d)(4) that the
procedures and presumptions of
<PAGE>   62
                                                                    Exhibit 20-A
                                                                     Page 6 of 7

this Paragraph 10 are not valid, binding and enforceable and shall stipulate in
any such court or before any such arbitrator that the Corporation is bound by
all the provisions of this Paragraph 10.

     (iv) In the event that the Indemnitee, pursuant to this Section (d)(4),
seeks a judicial adjudication of or an award in arbitration to enforce his
rights under, or to recover damages for breach of, this Paragraph 10, the
Indemnitee shall be entitled to recover from the Corporation, and shall be
indemnified by the Corporation against, any expenses actually and reasonably
incurred by the Indemnitee if the Indemnitee prevails in such judicial
adjudication or arbitration. If it shall be determined in such judicial
adjudication or arbitration that the Indemnitee is entitled to receive part but
not all of the indemnification or advancement of expenses sought, the expenses
incurred by the Indemnitee in connection with such judicial adjudication or
arbitration shall be prorated accordingly.

     (5) Definitions. For purposes of this Section (d):

     (i) "Change in Control" means (A) so long as the Public Utility Holding
Company Act of 1935 is in effect, any "company" becoming a "holding company" in
respect to the Corporation or any determination, by the Securities and Exchange
Commission that any "person" should be subject to the obligations, duties, and
liabilities if imposed by said Act by virtue or his, hers or its influence over
the management or policies of the Corporation, or (B) whether or not said Act is
in effect a change in control of the Corporation or a nature that would be
required to be reported in response to Item 6(e) of Schedule 14A of Regulation
14A promulgated under the Securities Exchange Act of 1934 (the "Act"), whether
or not the Corporation is then subject to such reporting requirement; provided
that, without limitation, such a change in control shall be deemed to have
occurred if (i) any "person" (as such term is used in Section 13(d) and 14(d) of
the Act) is or becomes the "beneficial owner" (as defined in Rule 13d-3 under
the Act), directly or indirectly, of securities of the Corporation representing
10% or more of the combined voting power of the Corporation's then outstanding
securities without the prior approval of at least two-thirds of the members of
the Board of Director in office immediately prior to such acquisition; (ii) the
Corporation is a party to a merger, consolidation, sale of assets or other
reorganization, or a proxy consent, as a consequence of which members of the
Board of Directors in office immediately prior to such transaction or event
constitute less than a majority of the Board of Directors thereafter; or (iii)
during any period of two consecutive years, individuals who at the beginning of
such period constituted the Board of Directors (including for this purpose any
new director whose election or nomination for election by the Corporation's
stockholders was approved by a vote of at least two-thirds of the directors then
still in office who were directors at the beginning of such period) cease for
any reason to constitute at least a majority of the Board of Directors.

     (ii) "Disinterested Director" means a director of the Corporation who is
not or was not a party to the Proceeding in respect of which indemnification is
sought by the Indemnitee.

     (iii) "Independent Counsel" means a law firm or a member of a law firm that
neither presently is, nor in the past five years has been, retained to the
representation: (A) the Corporation or the Indemnitee in any matter material to
either such party or (B) any other party to the proceeding giving rise to a
claim for indemnification under this Paragraph 10. Notwithstanding the
foregoing, the term "Independent Counsel" shall not include any person
<PAGE>   63
                                                                    Exhibit 20-A
                                                                     Page 7 of 7

who, under the applicable standards of professional conduct then prevailing
under the law of the State of Delaware, would have a conflict of interest in
representing either the Corporation or the Indemnitee is an action to determine
the Indemnitee's rights under this Paragraph 10.

     (e) Serverability. If any provision or provisions of the Paragraph 10 shall
be held to be invalid, illegal or unenforceable for any reason whatsoever: (i)
the validity, legality and enforceability of the remaining provision of this
Paragraph 10 (including, without limitation, all portions of any paragraph of
this Paragraph 10 containing any such provision held to be invalid, illegal or
unenforceable, that are not themselves invalid, illegal or unenforceable) shall
not in any way be affected or impaired thereby; and (ii) to the fullest extent
possible, the provisions of this Paragraph 10 (including, without limitation,
all portions of any paragraph of this Paragraph 10 containing any such provision
held to be invalid, illegal or unenforceable, that are not themselves invalid,
illegal or unenforceable) shall be construed so as to give effect to the intent
manifested by the provision held invalid, illegal or unenforceable.

     (f) Successor Laws, Regulations and Agencies. Reference herein to laws,
regulations or agencies shall be deemed to include all amendments thereof,
substitutions therefor and successors thereto.

     ELEVENTH. Meeting of the stockholders may be held within or without the
State of Delaware, as the by-laws may provide. The books of the Corporation may
be kept (subject to any provision contained in the statutes) outside the State
of Delaware at such place or places as may be designated from time to time by
the Board of Directors or in the by-laws of the Corporation. Elections of
directors need not be by written ballot unless the by-laws of the Corporation
shall so provide.

     TWELFTH. The Corporation reserves the right to amend, alter, change or
repeal any provision contained in this Certificate of Incorporation, in the
manner now or hereafter prescribed by statute, and all rights conferred upon
stockholders herein are granted subject to this reservation.

     I, THE UNDERSIGNED, being the incorporator hereinbefore named, for the
purpose of forming a corporation pursuant to the General Corporation Law of the
State of Delaware, do make this certificate, hereby declaring and certifying

of Directors.
<PAGE>   65
                                                                    Exhibit 21-A

       (b) Subject to the applicable provisions of the by-laws then in effect,
to determine, from time to time, whether and to what extent and at what times
and places and under what conditions and regulations the accounts and books and
documents of the Corporation, or any of them, shall be opened to the inspection
of the stockholders, and no stockholder shall have any right to inspect any
account or book or document of the Corporation, except as conferred by statute,
unless and until authorized so to do by resolution of the Board of Directors or
of the stockholders of the Corporation.

       (c) To authorize and cause to be executed mortgages and liens upon the
real and personal property of the Corporation.

       (d) To determine whether any, and, if any, what part, of the net profits

the stockholders, and to direct and determine the use and disposition of any
such net profits or such net assets in excess of capital.

       (e) To set apart out of any funds of the Corporation available for
dividends a reserve or reserves for any proper purpose and to abolish any such

extent provided in the resolution or in the by-laws of the Corporation, shall
have and may exercise the powers of the Board of Directors in the management of
the business and affairs of the Corporation, and may authorize the seal of the
Corporation to be affixed to all papers which may require it; provided, however,
the by-laws may provide that in the absence of disqualification of any member of
such committee or committees, the member or members thereof present at any
meeting and not disqualified from voting, whether or not he or they constitute a
quorum, may unanimously appoint another member of the Board of Directors to act
at the meeting in the place of any such absent or disqualified member.

       (g) When and as authorized by the affirmative vote of the holders of a
majority of the stock issued and outstanding having voting power given at a
stockholders' meeting duly called upon such notice as is required by statute, or
when authorized by the written consent of the holders of a majority of the
voting stock issued and outstanding, to sell, lease, or exchange all or
substantially all of the property and assets of the Corporation, including its
good will and its corporate franchises, upon such terms and conditions and for
such consideration, which may consist in whole or in part of money or property
including shares of stock in, and/or other securities of, any other corporation
or corporations, as its Board of Directors shall deem expedient and for the best
interests of the Corporation.

       (h) The Corporation may in its by-laws confer powers upon its Board of
Directors in addition to the foregoing and in addition to the powers and
authorities expressly conferred upon it by statute.

                                                                    Exhibit 21-A
                                                                     Page 3 of 7

       NINTH. To the fullest extent that the General Corporation Law of the
State of Delaware as it exists on the date hereof or as it may hereafter be
amended permits the limitation or elimination of the liability of directors, no
director of the Corporation shall be liable to the Corporation or its
stockholders for monetary damages for breach of fiduciary duty as a director. No
amendment to or repeal of this Paragraph 9 shall apply to or have any effect on
the liability of any director of the Corporation for or with respect to any acts
or omissions of such director occurring prior to such amendment or repeal.

       TENTH. (a) Right to Indemnification. The Corporation shall to the fullest
extent permitted by applicable law as then in effect indemnify any person (the
"Indemnitee") who was or is involved in any manner (including, without
limitation, as a party or a witness) or is threatened to be made so involved in
any threatened, pending or completed investigation, claim, action, suit or
proceeding, whether civil, criminal, administrative or investigative (including
without limitation, any action, suit or proceeding by or in the right of the
Corporation to procure a judgment in its favor) (a "Proceeding") by reason of
the fact that such person is or was a director, officer, employee or agent of
the Corporation, or is or was serving at the request of the Corporation as a
director, officer, employee or agent of another corporation, partnership, joint
venture, trust or other enterprise (including, without limitation, any employee
benefit plan) against all expenses (including attorneys' fees), judgments, fines
and amounts paid in settlement actually and reasonably incurred by such person
in connection with such Proceeding. Such indemnification shall be a contract
right and shall include the right to receive payment of any expenses incurred by
the Indemnitee in connection with such Proceeding in advance of its final
disposition, consistent with the provisions of applicable law as then in effect.

       (b) Insurance, Contracts and Funding. The Corporation may purchase and
maintain insurance to protect itself and any Indemnitee against any expenses,
judgments, fines and amounts paid in settlement as specified in Section (a) of
this Paragraph 10 or incurred by an Indemnitee in connection with any proceeding
referred to in Section (a) of this Paragraph 10, to the fullest extent permitted
by applicable law as then in effect. The Corporation may enter into contracts
with any director, officer, employee or agent of the Corporation in furtherance
of the provisions of this Paragraph 10 and may create a trust fund, grant a
security interest or use other means (including, without limitation, a letter of
credit) to ensure the payment of such amounts as may be necessary to effect
indemnification as provided in this Paragraph 10.

       (c) Indemnification; Not Exclusive Right. The right of indemnification
provided in this Paragraph 10 shall not be exclusive of any other rights to
which those seeking indemnification may otherwise be entitled, and the
provisions of this Paragraph 10 shall inure to the benefit of the heirs and
legal representatives of any person entitled to indemnity under this Paragraph
10 and shall be applicable to Proceedings commenced or continuing after the
adoption of this Paragraph 10, whether arising from acts or omissions occurring
before or after such adoption.

       (d) Advancement of Expenses; Procedures; Presumptions and Effect of
Certain Proceedings; Remedies. In furtherance, but not in limitation of the
foregoing provisions, the following procedures, presumptions and remedies shall
apply with respect to advancement of expenses and the right to indemnification
under this Paragraph 10:
<PAGE>   67
                                                                    Exhibit 21-A
                                                                     Page 4 of 7


       (1) Advance of Expenses. All reasonable expenses incurred by or on behalf
of the Indemnitee in connection with any Proceeding shall be advanced to the
Indemnitee by the Corporation within 20 days after the receipt by the
Corporation of a statement or statements from the Indemnitee requesting such
advance or advances from time to time, whether prior to or after final
disposition of such Proceeding. Such statement or statements shall reasonably
evidence the expenses incurred by the Indemnitee and, if required by law at the
time of such advance, shall include or be accompanied by an undertaking by, or
on behalf of, the Indemnitee to repay the amounts advanced if it should
ultimately be determined that the Indemnitee is not entitled to be indemnified
against such expenses pursuant to this Paragraph 10.

       (2) Procedure for Determination of Entitlement to Indemnification. (i) To
obtain indemnification under this Paragraph 10, an Indemnitee shall submit to
the Secretary of the Corporation a written request including such documentation
and information as is reasonably available to the Indemnitee and reasonably
necessary to determine whether and to what extent the Indemnitee is entitled to
indemnification (the "Supporting Documentation"). The determination of the
Indemnitee's entitlement to indemnification shall be made not later than 60 days
after receipt by the Corporation of the written request for indemnification
together with Supporting Documentation. The Secretary of the Corporation shall,
promptly upon receipt of such a request for indemnification, advise the Board of
Directors in writing the Indemnitee has requested indemnification.

       (ii) The Indemnitee's entitlement to indemnification under this Paragraph
10 shall be determined in one of the following ways: (A) by a majority vote of
the Disinterested Directors (as hereinafter defined), if they constitute a
quorum of the Board of Directors; (B) by a written opinion of Independent
Counsel (as hereinafter defined) if (x) a Change of Control (as hereinafter
defined) shall have occurred and the Indemnitee so requests or (y) a quorum of
the Board of Directors consisting of Disinterested Directors is not obtainable
or, even if obtainable, a majority of such Disinterested Directors so directs;
(C) by the stockholders of the Corporation (but only if a majority of the
Disinterested Directors, if they constitute a quorum of the Board of Directors,
present the issue of entitlement to indemnification to the stockholders for
their determination); or (D) as provided in Section (d)(3).

       (iii) In the event the determination of entitlement to indemnification is
to be made by Independent Counsel pursuant to Section (d)(2)(ii), a majority of
the Disinterested Directors shall select the Independent Counsel, but only an
Independent Counsel to which the Indemnitee does not reasonably object;
provided, however, that if a Change of Control shall have occurred, the
Indemnitee shall select such Independent Counsel, but only an Independent
Counsel to which the Board of Directors does not reasonably object.

       (iv) The only basis upon which a finding of no entitlement to
indemnification may be made is that indemnification is prohibited by law.

       (3) Presumptions and Effect of Certain Proceedings. Except as otherwise
expressly provided in this Paragraph 10, if a Change of Control shall have
occurred, the Indemnitee shall be presumed to be entitled to indemnification
under this Paragraph 10 upon submission of a request for indemnification
together with the Supporting Documentation in accordance with Section (d)(2)(i),
and thereafter the Corporation shall have the burden of proof to overcome that
presumption in reaching a contrary determination. In any event, if the person or
persons
<PAGE>   68
                                                                    Exhibit 21-A
                                                                     Page 5 of 7


empowered under Section (d)(2) to determine entitlement to indemnification shall
not have been appointed or shall not have made a determination within 60 days
after receipt by the Corporation of the request therefor together with the
Supporting Documentation, the Indemnitee shall be deemed to be entitled to
indemnification and the Indemnitee shall be entitled to such indemnification
unless (A) the Indemnitee misrepresented or failed to disclose a material fact
in making the request for indemnification or in the Supporting Documentation or
(B) such indemnification is prohibited by law. The termination of any Proceeding
described in Section (a), or of any claim, issue or matter therein, by judgment,
order settlement or conviction, or upon a pleas of nolo contendere or its
equivalent, shall not, of itself, adversely affect the right of the Indemnitee
to indemnification or create a presumption that the Indemnitee did not act in
good faith and in a manner which the Indemnitee reasonably believed to be in or
not opposed to the best interests of the Corporation or, with respect to any
criminal Proceeding, that the Indemnitee had reasonable cause to believe that
the Indemnitee's conduct was unlawful.

       (4) Remedies of Indemnitee.

       (i) In the event that a determination is made pursuant to Section (d)(2)
or (3), that the Indemnitee is not entitled to indemnification under this
Paragraph 10, (A) the Indemnitee shall be entitled to seek an adjudication of
his entitlement to such indemnification either, at the Indemnitee's sole option,
in (x) an appropriate court of the State of Delaware or any other court of
competent jurisdiction or (y) an arbitration to be conducted by a single
arbitrator pursuant to the rules of the American Arbitration Association; (B)
any such judicial proceeding or arbitration shall be de novo and the Indemnitee
shall not be prejudiced by reason of such adverse determination; and (C) in any
such judicial proceeding or arbitration the Corporation shall have the burden of
proving that the Indemnitee is not entitled to indemnification under this
Paragraph 10.

       (ii) If a determination shall have been made or deemed to have been made,
pursuant to Section (d)(2) or (3), that the Indemnitee is entitled to
Indemnitee, the Corporation shall be obligated to pay the amounts constituting
such indemnification within five days after such determination has been made or
deemed to have been made and shall be conclusively bound by such determination
unless (A) the Indemnitee misrepresented or failed to disclose a material fact
in making the request for indemnification or in the Supporting Documentation or
(B) such indemnification or in the Supporting Documentation or (C) such
indemnification is prohibited by law. In the event that (x) advancement of
expenses if not timely made pursuant to Section (d)(l) or (y) payment of
indemnification is not made within five days after a determination of
entitlement to indemnification has been made or deemed to have been made
pursuant to Section (d)(2) or (3), the Indemnitee shall be entitled to seek
judicial enforcement of the Corporation's obligation to pay to the Indemnitee
such advancement of expenses or indemnification. Notwithstanding the foregoing,
the Corporation may bring an action, in an appropriate court in the State of
Delaware or any other court of competent jurisdiction, contesting the right of
the Indemnitee to receive indemnification hereunder due to the occurrence of an
event described in subclause (A) or (B) of this clause (ii) (a "Disqualifying
Event"); provided, however, that in any such action the Corporation shall have
the burden of proving the occurrence of such Disqualifying Event.

       (iii) The Corporation shall be precluded from asserting in any judicial
proceeding or arbitration commenced pursuant to this Section (d)(4) that the
procedures and presumptions of
<PAGE>   69
                                                                    Exhibit 21-A
                                                                     Page 6 of 7


this Paragraph 10 are not valid, binding and enforceable and shall stipulate in
any such court or before any such arbitrator that the Corporation is bound by
all the provisions of this Paragraph 10.

       (iv) In the event that the Indemnitee, pursuant to this Section (d)(4),
seeks a judicial adjudication of or an award in arbitration to enforce his
rights under, or to recover damages for breach of, this Paragraph 10, the
Indemnitee shall be entitled to recover from the Corporation, and shall be
indemnified by the Corporation against, any expenses actually and reasonably
incurred by the Indemnitee if the Indemnitee prevails in such judicial
adjudication or arbitration. If it shall be determined in such judicial
adjudication or arbitration that the Indemnitee is entitled to receive part but
not all of the indemnification or advancement of expenses sought, the expenses
incurred by the Indemnitee in connection with such judicial adjudication or
arbitration shall be prorated accordingly.

       (5) Definitions. For purposes of this Section (d):

       (i) "Change in Control" means (A) so long as the Public Utility Holding
Company Act of 1935 is in effect, any "company" becoming a "holding company" in
respect to the Corporation or any determination, by the Securities and Exchange
Commission that any "person" should be subject to the obligations, duties, and
liabilities if imposed by said Act by virtue or his, hers or its influence over
the management or policies of the Corporation, or (B) whether or not said Act is
in effect a change in control of the Corporation or a nature that would be
required to be reported in response to Item 6(e) of Schedule 14A of Regulation
14A promulgated under the Securities Exchange Act of 1934 (the "Act"), whether
or not the Corporation is then subject to such reporting requirement; provided
that, without limitation, such a change in control shall be deemed to have
occurred if (i) any "person" (as such term is used in Section 13(d) and 14(d) of
the Act) is or becomes the "beneficial owner" (as defined in Rule 13d-3 under
the Act), directly or indirectly, of securities of the Corporation representing
10% or more of the combined voting power of the Corporation's then outstanding
securities without the prior approval of at least two-thirds of the members of
the Board of Director in office immediately prior to such acquisition; (ii) the
Corporation is a party to a merger, consolidation, sale of assets or other
reorganization, or a proxy consent, as a consequence of which members of the
Board of Directors in office immediately prior to such transaction or event
constitute less than a majority of the Board of Directors thereafter; or (iii)
during any period of two consecutive years, individuals who at the beginning of
such period constituted the Board of Directors (including for this purpose any
new director whose election or nomination for election by the Corporation's
stockholders was approved by a vote of at least two-thirds of the directors then
still in office who were directors at the beginning of such period) cease for
any reason to constitute at least a majority of the Board of Directors.

       (ii) "Disinterested Director" means a director of the Corporation who is
not or was not a party to the Proceeding in respect of which indemnification is
sought by the Indemnitee.

       (iii) "Independent Counsel" means a law firm or a member of a law firm
that neither presently is, nor in the past five years has been, retained to the
representation: (A) the Corporation or the Indemnitee in any matter material to
either such party or (B) any other party to the proceeding giving rise to a
claim for indemnification under this Paragraph 10. Notwithstanding the
foregoing, the term "Independent Counsel" shall not include any person
<PAGE>   70
                                                                    Exhibit 21-A
                                                                     Page 7 of 7


who, under the applicable standards of professional conduct then prevailing
under the law of the State of Delaware, would have a conflict of interest in
representing either the Corporation or the Indemnitee is an action to determine
the Indemnitee's rights under this Paragraph 10.

       (e) Serverability. If any provision or provisions of the Paragraph 10
shall be held to be invalid, illegal or unenforceable for any reason whatsoever:
(i) the validity, legality and enforceability of the remaining provision of this
Paragraph 10 (including, without limitation, all portions of any paragraph of
this Paragraph 10 containing any such provision held to be invalid, illegal or
unenforceable, that are not themselves invalid, illegal or unenforceable) shall
not in any way be affected or impaired thereby; and (ii) to the fullest extent
possible, the provisions of this Paragraph 10 (including, without limitation,
all portions of any paragraph of this Paragraph 10 containing any such provision
held to be invalid, illegal or unenforceable, that are not themselves invalid,
illegal or unenforceable) shall be construed so as to give effect to the intent
manifested by the provision held invalid, illegal or unenforceable.

       (f) Successor Laws, Regulations and Agencies. Reference herein to laws,
regulations or agencies shall be deemed to include all amendments thereof,
substitutions therefor and successors thereto.

       ELEVENTH. Meeting of the stockholders may be held within or without the
State of Delaware, as the by-laws may provide. The books of the Corporation may
be kept (subject to any provision contained in the statutes) outside the State
of Delaware at such place or places as may be designated from time to time by
the Board of Directors or in the by-laws of the Corporation. Elections of
directors need not be by written ballot unless the by-laws of the Corporation
shall so provide.

       TWELFTH. The Corporation reserves the right to amend, alter, change or
repeal any provision contained in this Certificate of Incorporation, in the
manner now or hereafter prescribed by statute, and all rights conferred upon
stockholders herein are granted subject to this reservation.

       I, THE UNDERSIGNED, being the incorporator hereinbefore named, for the
purpose of forming a corporation pursuant to the General Corporation Law of the
State of Delaware, do make this certificate, hereby declaring and certifying
that this is my act and deed and the facts herein stated are true, and

                                                                    Exhibit 22-A
                                                                     Page 2 of 7


       (b) Subject to the applicable provisions of the by-laws then in effect,
to determine, from time to time, whether and to what extent and at what times
and places and under what conditions and regulations the accounts and books and
documents of the Corporation, or any of them, shall be opened to the inspection
of the stockholders, and no stockholder shall have any right to inspect any
account or book or document of the Corporation, except as conferred by statute,
unless and until authorized so to do by resolution of the Board of Directors or
of the stockholders of the Corporation.

       (c) To authorize and cause to be executed mortgages and liens upon the
real and personal property of the Corporation.

       (d) To determine whether any, and, if any, what part, of the net profits
of the Corporation or of its surplus shall be declared in dividends and paid to
the stockholders, and to direct and determine the use and disposition of any
such net profits or such net assets in excess of capital.

       (e) To set apart out of any funds of the Corporation available for
dividends a reserve or reserves for any proper purpose and to abolish any such
reserve or reserves, to make such other provisions, if any, as the Board of
Directors may deem necessary or advisable for working capital, for additions,
improvements and betterments to plant and equipment, for expansion of the
business of the Corporation (including the acquisition of real and personal
property for that purpose) and for any other purposes of the Corporation.

       (f) By resolution or resolutions passed by a majority of the whole Board,
to designate one or more committees, each committee to consist of two or more of
the directors of the Corporation. The Board may designate one or more directors
as alternate members of any committee, who may replace any absent or
disqualified member at any meeting of the committee. Any such committee, to the
extent provided in the resolution or in the by-laws of the Corporation, shall
have and may exercise the powers of the Board of Directors in the management of
the business and affairs of the Corporation, and may authorize the seal of the
Corporation to be affixed to all papers which may require it; provided, however,
the by-laws may provide that in the absence of disqualification of any member of
such committee or committees, the member or members thereof present at any
meeting and not disqualified from voting, whether or not he or they constitute a
quorum, may unanimously appoint another member of the Board of Directors to act
at the meeting in the place of any such absent or disqualified member.

       (g) When and as authorized by the affirmative vote of the holders of a
majority of the stock issued and outstanding having voting power given at a
stockholders' meeting duly called upon such notice as is required by statute, or
when authorized by the written consent of the holders of a majority of the
voting stock issued and outstanding, to sell, lease, or exchange all or
substantially all of the property and assets of the Corporation, including its
good will and its corporate franchises, upon such terms and conditions and for
such consideration, which may consist in whole or in part of money or property
including shares of stock in, and/or other securities of, any other corporation
or corporations, as its Board of Directors shall deem expedient and for the best
interests of the Corporation.

       (h) The Corporation may in its by-laws confer powers upon its Board of
Directors in addition to the foregoing and in addition to the powers and
authorities expressly conferred upon
<PAGE>   73
                                                                    Exhibit 22-A
                                                                     Page 3 of 7


it by statute.

       NINTH. To the fullest extent that the General Corporation Law of the
State of Delaware as it exists on the date hereof or as it may hereafter be
amended permits the limitation or elimination of the liability of directors, no
director of the Corporation shall be liable to the Corporation or its
stockholders for monetary damages for breach of fiduciary duty as a director. No
amendment to or repeal of this Paragraph 9 shall apply to or have any effect on
the liability of any director of the Corporation for or with respect to any acts
or omissions of such director occurring prior to such amendment or repeal.

       TENTH. (a) Right to Indemnification. The Corporation shall to the fullest
extent permitted by applicable law as then in effect indemnify any person (the
"Indemnitee") who was or is involved in any manner (including, without
limitation, as a party or a witness) or is threatened to be made so involved in
any threatened, pending or completed investigation, claim, action, suit or
proceeding, whether civil, criminal, administrative or investigative (including
without limitation, any action, suit or proceeding by or in the right of the
Corporation to procure a judgment in its favor) (a "Proceeding") by reason of
the fact that such person is or was a director, officer, employee or agent of
the Corporation, or is or was serving at the request of the Corporation as a
director, officer, employee or agent of another corporation, partnership, joint
venture, trust or other enterprise (including, without limitation, any employee
benefit plan) against all expenses (including attorneys' fees), judgments, fines
and amounts paid in settlement actually and reasonably incurred by such person
in connection with such Proceeding. Such indemnification shall be a contract
right and shall include the right to receive payment of any expenses incurred by
the Indemnitee in connection with such Proceeding in advance of its final
disposition, consistent with the provisions of applicable law as then in effect.

       (b) Insurance, Contracts and Funding. The Corporation may purchase and
maintain insurance to protect itself and any Indemnitee against any expenses,
judgments, fines and amounts paid in settlement as specified in Section (a) of
this Paragraph 10 or incurred by an Indemnitee in connection with any proceeding
referred to in Section (a) of this Paragraph 10, to the fullest extent permitted
by applicable law as then in effect. The Corporation may enter into contracts
with any director, officer, employee or agent of the Corporation in furtherance
of the provisions of this Paragraph 10 and may create a trust fund, grant a
security interest or use other means (including, without limitation, a letter of
credit) to ensure the payment of such amounts as may be necessary to effect
indemnification as provided in this Paragraph 10.

       (c) Indemnification; Not Exclusive Right. The right of indemnification
provided in this Paragraph 10 shall not be exclusive of any other rights to
which those seeking indemnification may otherwise be entitled, and the
provisions of this Paragraph 10 shall inure to the benefit of the heirs and
legal representatives of any person entitled to indemnity under this Paragraph
10 and shall be applicable to Proceedings commenced or continuing after the
adoption of this Paragraph 10, whether arising from acts or omissions occurring
before or after such adoption.

       (d) Advancement of Expenses; Procedures; Presumptions and Effect of
Certain Proceedings; Remedies. In furtherance, but not in limitation of the
foregoing provisions, the following procedures, presumptions and remedies shall
apply with respect to advancement of expenses and the right to indemnification
under this Paragraph 10:
<PAGE>   74
                                                                    Exhibit 22-A
                                                                     Page 4 of 7


       (1) Advance of Expenses. All reasonable expenses incurred by or on behalf
of the Indemnitee in connection with any Proceeding shall be advanced to the
Indemnitee by the Corporation within 20 days after the receipt by the
Corporation of a statement or statements from the Indemnitee requesting such
advance or advances from time to time, whether prior to or after final
disposition of such Proceeding. Such statement or statements shall reasonably
evidence the expenses incurred by the Indemnitee and, if required by law at the
time of such advance, shall include or be accompanied by an undertaking by, or
on behalf of, the Indemnitee to repay the amounts advanced if it should
ultimately be determined that the Indemnitee is not entitled to be indemnified
against such expenses pursuant to this Paragraph 10.

       (2) Procedure for Determination of Entitlement to Indemnification. (i) To
obtain indemnification under this Paragraph 10, an Indemnitee shall submit to
the Secretary of the Corporation a written request including such documentation
and information as is reasonably available to the Indemnitee and reasonably
necessary to determine whether and to what extent the Indemnitee is entitled to
indemnification (the "Supporting Documentation"). The determination of the
Indemnitee's entitlement to indemnification shall be made not later than 60 days
after receipt by the Corporation of the written request for indemnification
together with Supporting Documentation. The Secretary of the Corporation shall,
promptly upon receipt of such a request for indemnification, advise the Board of
Directors in writing the Indemnitee has requested indemnification.

       (ii) The Indemnitee's entitlement to indemnification under this Paragraph
10 shall be determined in one of the following ways: (A) by a majority vote of
the Disinterested Directors (as hereinafter defined), if they constitute a
quorum of the Board of Directors; (B) by a written opinion of Independent
Counsel (as hereinafter defined) if (x) a Change of Control (as hereinafter
defined) shall have occurred and the Indemnitee so requests or (y) a quorum of
the Board of Directors consisting of Disinterested Directors is not obtainable
or, even if obtainable, a majority of such Disinterested Directors so directs;
(C) by the stockholders of the Corporation (but only if a majority of the
Disinterested Directors, if they constitute a quorum of the Board of Directors,
present the issue of entitlement to indemnification to the stockholders for
their determination); or (D) as provided in Section (d)(3).

       (iii) In the event the determination of entitlement to indemnification is
to be made by Independent Counsel pursuant to Section (d)(2)(ii), a majority of
the Disinterested Directors shall select the Independent Counsel, but only an
Independent Counsel to which the Indemnitee does not reasonably object;
provided, however, that if a Change of Control shall have occurred, the
Indemnitee shall select such Independent Counsel, but only an Independent
Counsel to which the Board of Directors does not reasonably object.

       (iv) The only basis upon which a finding of no entitlement to
indemnification may be made is that indemnification is prohibited by law.

       (3) Presumptions and Effect of Certain Proceedings. Except as otherwise
expressly provided in this Paragraph 10, if a Change of Control shall have
occurred, the Indemnitee shall be presumed to be entitled to indemnification
under this Paragraph 10 upon submission of a request for indemnification
together with the Supporting Documentation in accordance with Section (d)(2)(i),
and thereafter the Corporation shall have the burden of proof to overcome that
presumption in reaching a contrary determination. In any event, if the person or
persons
<PAGE>   75
                                                                    Exhibit 22-A
                                                                     Page 5 of 7


empowered under Section (d)(2) to determine entitlement to indemnification shall
not have been appointed or shall not have made a determination within 60 days
after receipt by the Corporation of the request therefor together with the
Supporting Documentation, the Indemnitee shall be deemed to be entitled to
indemnification and the Indemnitee shall be entitled to such indemnification
unless (A) the Indemnitee misrepresented or failed to disclose a material fact
in making the request for indemnification or in the Supporting Documentation or
(B) such indemnification is prohibited by law. The termination of any Proceeding
described in Section (a), or of any claim, issue or matter therein, by judgment,
order settlement or conviction, or upon a pleas of nolo contendere or its
equivalent, shall not, of itself, adversely affect the right of the Indemnitee
to indemnification or create a presumption that the Indemnitee did not act in
good faith and in a manner which the Indemnitee reasonably believed to be in or
not opposed to the best interests of the Corporation or, with respect to any
criminal Proceeding, that the Indemnitee had reasonable cause to believe that
the Indemnitee's conduct was unlawful.

       (4) Remedies of Indemnitee.

       (i) In the event that a determination is made pursuant to Section (d)(2)
or (3), that the Indemnitee is not entitled to indemnification under this
Paragraph 10, (A) the Indemnitee shall be entitled to seek an adjudication of
his entitlement to such indemnification either, at the Indemnitee's sole option,
in (x) an appropriate court of the State of Delaware or any other court of
competent jurisdiction or (y) an arbitration to be conducted by a single
arbitrator pursuant to the rules of the American Arbitration Association; (B)
any such judicial proceeding or arbitration shall be de novo and the Indemnitee
shall not be prejudiced by reason of such adverse determination; and (C) in any
such judicial proceeding or arbitration the Corporation shall have the burden of
proving that the Indemnitee is not entitled to indemnification under this
Paragraph 10.

       (ii) If a determination shall have been made or deemed to have been made,
pursuant to Section (d)(2) or (3), that the Indemnitee is entitled to
Indemnitee, the Corporation shall be obligated to pay the amounts constituting
such indemnification within five days after such determination has been made or
deemed to have been made and shall be conclusively bound by such determination
unless (A) the Indemnitee misrepresented or failed to disclose a material fact
in making the request for indemnification or in the Supporting Documentation or
(B) such indemnification or in the Supporting Documentation or (C) such
indemnification is prohibited by law. In the event that (x) advancement of
expenses if not timely made pursuant to Section (d)(l) or (y) payment of
indemnification is not made within five days after a determination of
entitlement to indemnification has been made or deemed to have been made
pursuant to Section (d)(2) or (3), the Indemnitee shall be entitled to seek
judicial enforcement of the Corporation's obligation to pay to the Indemnitee
such advancement of expenses or indemnification. Notwithstanding the foregoing,
the Corporation may bring an action, in an appropriate court in the State of
Delaware or any other court of competent jurisdiction, contesting the right of
the Indemnitee to receive indemnification hereunder due to the occurrence of an
event described in subclause (A) or (B) of this clause (ii) (a "Disqualifying
Event"); provided, however, that in any such action the Corporation shall have
the burden of proving the occurrence of such Disqualifying Event.

       (iii) The Corporation shall be precluded from asserting in any judicial
proceeding or arbitration commenced pursuant to this Section (d)(4) that the
procedures and presumptions of
<PAGE>   76
                                                                    Exhibit 22-A
                                                                     Page 6 of 7


this Paragraph 10 are not valid, binding and enforceable and shall stipulate in
any such court or before any such arbitrator that the Corporation is bound by
all the provisions of this Paragraph 10.

       (iv) In the event that the Indemnitee, pursuant to this Section (d)(4),
seeks a judicial adjudication of or an award in arbitration to enforce his
rights under, or to recover damages for breach of, this Paragraph 10, the
Indemnitee shall be entitled to recover from the Corporation, and shall be
indemnified by the Corporation against, any expenses actually and reasonably
incurred by the Indemnitee if the Indemnitee prevails in such judicial
adjudication or arbitration. If it shall be determined in such judicial
adjudication or arbitration that the Indemnitee is entitled to receive part but
not all of the indemnification or advancement of expenses sought, the expenses
incurred by the Indemnitee in connection with such judicial adjudication or
arbitration shall be prorated accordingly.

       (5) Definitions. For purposes of this Section (d):

       (i) "Change in Control" means (A) so long as the Public Utility Holding
Company Act of 1935 is in effect, any "company" becoming a "holding company" in
respect to the Corporation or any determination, by the Securities and Exchange
Commission that any "person" should be subject to the obligations, duties, and
liabilities if imposed by said Act by virtue or his, hers or its influence over
the management or policies of the Corporation, or (B) whether or not said Act is
in effect a change in control of the Corporation or a nature that would be
required to be reported in response to Item 6(e) of Schedule 14A of Regulation
14A promulgated under the Securities Exchange Act of 1934 (the "Act"), whether
or not the Corporation is then subject to such reporting requirement; provided
that, without limitation, such a change in control shall be deemed to have
occurred if (i) any "person" (as such term is used in Section 13(d) and 14(d) of
the Act) is or becomes the "beneficial owner" (as defined in Rule 13d-3 under
the Act), directly or indirectly, of securities of the Corporation representing
10% or more of the combined voting power of the Corporation's then outstanding
securities without the prior approval of at least two-thirds of the members of
the Board of Director in office immediately prior to such acquisition; (ii) the
Corporation is a party to a merger, consolidation, sale of assets or other
reorganization, or a proxy consent, as a consequence of which members of the
Board of Directors in office immediately prior to such transaction or event
constitute less than a majority of the Board of Directors thereafter; or (iii)
during any period of two consecutive years, individuals who at the beginning of
such period constituted the Board of Directors (including for this purpose any
new director whose election or nomination for election by the Corporation's
stockholders was approved by a vote of at least two-thirds of the directors then
still in office who were directors at the beginning of such period) cease for
any reason to constitute at least a majority of the Board of Directors.

       (ii) "Disinterested Director" means a director of the Corporation who is
not or was not a party to the Proceeding in respect of which indemnification is
sought by the Indemnitee.

       (iii) "Independent Counsel" means a law firm or a member of a law firm
that neither presently is, nor in the past five years has been, retained to the
representation: (A) the Corporation or the Indemnitee in any matter material to
either such party or (B) any other party to the proceeding giving rise to a
claim for indemnification under this Paragraph 10. Notwithstanding the
foregoing, the term "Independent Counsel" shall not include any person

                                                                    Exhibit 22-A
                                                                     Page 7 of 7


who, under the applicable standards of professional conduct then prevailing
under the law of the State of Delaware, would have a conflict of interest in
representing either the Corporation or the Indemnitee is an action to determine
the Indemnitee's rights under this Paragraph 10.

       (e) Serverability. If any provision or provisions of the Paragraph 10
shall be held to be invalid, illegal or unenforceable for any reason whatsoever:
(i) the validity, legality and enforceability of the remaining provision of this
Paragraph 10 (including, without limitation, all portions of any paragraph of
this Paragraph 10 containing any such provision held to be invalid, illegal or
unenforceable, that are not themselves invalid, illegal or unenforceable) shall
not in any way be affected or impaired thereby; and (ii) to the fullest extent
possible, the provisions of this Paragraph 10 (including, without limitation,
all portions of any paragraph of this Paragraph 10 containing any such provision
held to be invalid, illegal or unenforceable, that are not themselves invalid,
illegal or unenforceable) shall be construed so as to give effect to the intent
manifested by the provision held invalid, illegal or unenforceable.

       (f) Successor Laws, Regulations and Agencies. Reference herein to laws,
regulations or agencies shall be deemed to include all amendments thereof,
substitutions therefor and successors thereto.

       ELEVENTH. Meeting of the stockholders may be held within or without the
State of Delaware, as the by-laws may provide. The books of the Corporation may
be kept (subject to any provision contained in the statutes) outside the State
of Delaware at such place or places as may be designated from time to time by
the Board of Directors or in the by-laws of the Corporation. Elections of
directors need not be by written ballot unless the by-laws of the Corporation
shall so provide.

       TWELFTH. The Corporation reserves the right to amend, alter, change or
repeal any provision contained in this Certificate of Incorporation, in the
manner now or hereafter prescribed by statute, and all rights conferred upon
stockholders herein are granted subject to this reservation.

       I, THE UNDERSIGNED, being the incorporator hereinbefore named, for the
purpose of forming a corporation pursuant to the General Corporation Law of the
State of Delaware, do make this certificate, hereby declaring and certifying
that this is my act and deed and the facts herein stated are true, and

Directors may deem necessary or advisable for working capital, for additions,
improvements and betterments to plant and equipment, for expansion of the
business of the Corporation (including the acquisition of real and personal
property for that purpose) and for any other purposes of the Corporation.

         (f) By resolution or resolutions passed by a majority of the whole
Board, to designate one or more committees, each committee to consist of two or
more of the directors of the Corporation. The Board may designate one or more
directors as alternate members of any committee, who may replace any absent or
disqualified member at any meeting of the committee. Any such committee, to the
extent provided in the resolution or in the by-laws of the Corporation, shall
have and may exercise the powers of the Board of Directors in the management of
the business and affairs of the Corporation, and may authorize the seal of the
Corporation to be affixed to all papers which may require it; provided, however,
the by-laws may provide that in the absence of disqualification of any member of
such committee or committees, the member or members thereof present at any
meeting and not disqualified from voting, whether or not he or they constitute a
quorum, may unanimously appoint another member of the Board of Directors to act
at the meeting in the place of any such absent or disqualified member.

         (g) When and as authorized by the affirmative vote of the holders of a
majority of the stock issued and outstanding having voting power given at a
stockholders' meeting duly called upon such notice as is required by statute, or
when authorized by the written consent of the holders of a majority of the
voting stock issued and outstanding, to sell, lease, or exchange all or
substantially all of the property and assets of the Corporation, including its
good will and its corporate franchises, upon such terms and conditions and for
such consideration, which may consist in whole or in part of money or property
including shares of stock in, and/or other securities of, any other corporation
or corporations, as its Board of Directors shall deem expedient and for the best
interests of the Corporation.

         (h) The Corporation may in its by-laws confer powers upon its Board of
Directors in addition to the foregoing and in addition to the powers and
authorities expressly conferred upon it by statute.

                                                                     Page 3 of 7



         NINTH. To the fullest extent that the General Corporation Law of the
State of Delaware as it exists on the date hereof or as it may hereafter be
amended permits the limitation or elimination of the liability of directors, no
director of the Corporation shall be liable to the Corporation or its
stockholders for monetary damages for breach of fiduciary duty as a director. No
amendment to or repeal of this Paragraph 9 shall apply to or have any effect on
the liability of any director of the Corporation for or with respect to any acts
or omissions of such director occurring prior to such amendment or repeal.

         TENTH. (a) Right to Indemnification. The Corporation shall to the
fullest extent permitted by applicable law as then in effect indemnify any
person (the "Indemnitee") who was or is involved in any manner (including,
without limitation, as a party or a witness) or is threatened to be made so
involved in any threatened, pending or completed investigation, claim, action,
suit or proceeding, whether civil, criminal, administrative or investigative
(including without limitation, any action, suit or proceeding by or in the right
of the Corporation to procure a judgment in its favor) (a "Proceeding") by
reason of the fact that such person is or was a director, officer, employee or
agent of the Corporation, or is or was serving at the request of the Corporation
as a director, officer, employee or agent of another corporation, partnership,
joint venture, trust or other enterprise (including, without limitation, any
employee benefit plan) against all expenses (including attorneys' fees),
judgments, fines and amounts paid in settlement actually and reasonably incurred
by such person in connection with such Proceeding. Such indemnification shall be
a contract right and shall include the right to receive payment of any expenses
incurred by the Indemnitee in connection with such Proceeding in advance of its
final disposition, consistent with the provisions of applicable law as then in
effect.

         (b) Insurance, Contracts and Funding. The Corporation may purchase and
maintain insurance to protect itself and any Indemnitee against any expenses,
judgments, fines and amounts paid in settlement as specified in Section (a) of
this Paragraph 10 or incurred by an Indemnitee in connection with any proceeding
referred to in Section (a) of this Paragraph 10, to the fullest extent permitted
by applicable law as then in effect. The Corporation may enter into contracts
with any director, officer, employee or agent of the Corporation in furtherance
of the provisions of this Paragraph 10 and may create a trust fund, grant a
security interest or use other means (including, without limitation, a letter of
credit) to ensure the payment of such amounts as may be necessary to effect
indemnification as provided in this Paragraph 10.

         (c) Indemnification; Not Exclusive Right. The right of indemnification
provided in this Paragraph 10 shall not be exclusive of any other rights to
which those seeking indemnification may otherwise be entitled, and the
provisions of this Paragraph 10 shall inure to the benefit of the heirs and
legal representatives of any person entitled to indemnity under this Paragraph
10 and shall be applicable to Proceedings commenced or continuing after the
adoption of this Paragraph 10, whether arising from acts or omissions occurring
before or after such adoption.

         (d) Advancement of Expenses; Procedures; Presumptions and Effect of
Certain Proceedings; Remedies. In furtherance, but not in limitation of the
foregoing provisions, the following procedures, presumptions and remedies shall
apply with respect to advancement of expenses and the right to indemnification
under this Paragraph 10:

         (1) Advance of Expenses. All reasonable expenses incurred by or on
behalf of the
<PAGE>   81
                                                                    Exhibit 23-A
                                                                     Page 4 of 7



Indemnitee in connection with any Proceeding shall be advanced to the Indemnitee
by the Corporation within 20 days after the receipt by the Corporation of a
statement or statements from the Indemnitee requesting such advance or advances
from time to time, whether prior to or after final disposition of such
Proceeding. Such statement or statements shall reasonably evidence the expenses
incurred by the Indemnitee and, if required by law at the time of such advance,
shall include or be accompanied by an undertaking by, or on behalf of, the
Indemnitee to repay the amounts advanced if it should ultimately be determined
that the Indemnitee is not entitled to be indemnified against such expenses
pursuant to this Paragraph 10.

         (2) Procedure for Determination of Entitlement to Indemnification. (i)
To obtain indemnification under this Paragraph 10, an Indemnitee shall submit to
the Secretary of the Corporation a written request including such documentation
and information as is reasonably available to the Indemnitee and reasonably
necessary to determine whether and to what extent the Indemnitee is entitled to
indemnification (the "Supporting Documentation"). The determination of the
Indemnitee's entitlement to indemnification shall be made not later than 60 days
after receipt by the Corporation of the written request for indemnification
together with Supporting Documentation. The Secretary of the Corporation shall,
promptly upon receipt of such a request for indemnification, advise the Board of
Directors in writing the Indemnitee has requested indemnification.

         (ii) The Indemnitee's entitlement to indemnification under this
Paragraph 10 shall be determined in one of the following ways: (A) by a majority
vote of the Disinterested Directors (as hereinafter defined), if they constitute
a quorum of the Board of Directors; (B) by a written opinion of Independent
Counsel (as hereinafter defined) if (x) a Change of Control (as hereinafter
defined) shall have occurred and the Indemnitee so requests or (y) a quorum of
the Board of Directors consisting of Disinterested Directors is not obtainable
or, even if obtainable, a majority of such Disinterested Directors so directs;
(C) by the stockholders of the Corporation (but only if a majority of the
Disinterested Directors, if they constitute a quorum of the Board of Directors,
present the issue of entitlement to indemnification to the stockholders for
their determination); or (D) as provided in Section (d)(3).

         (iii) In the event the determination of entitlement to indemnification
is to be made by Independent Counsel pursuant to Section (d)(2)(ii), a majority
of the Disinterested Directors shall select the Independent Counsel, but only an
Independent Counsel to which the Indemnitee does not reasonably object;
provided, however, that if a Change of Control shall have occurred, the
Indemnitee shall select such Independent Counsel, but only an Independent
Counsel to which the Board of Directors does not reasonably object.

         (iv) The only basis upon which a finding of no entitlement to
indemnification may be made is that indemnification is prohibited by law.

         (3) Presumptions and Effect of Certain Proceedings. Except as otherwise
expressly provided in this Paragraph 10, if a Change of Control shall have
occurred, the Indemnitee shall be presumed to be entitled to indemnification
under this Paragraph 10 upon submission of a request for indemnification
together with the Supporting Documentation in accordance with Section (d)(2)(i),
and thereafter the Corporation shall have the burden of proof to overcome that
presumption in reaching a contrary determination. In any event, if the person or
persons empowered under Section (d)(2) to determine entitlement to
indemnification shall not have been
<PAGE>   82
                                                                    Exhibit 23-A
                                                                     Page 5 of 7



appointed or shall not have made a determination within 60 days after receipt by
the Corporation of the request therefor together with the Supporting
Documentation, the Indemnitee shall be deemed to be entitled to indemnification
and the Indemnitee shall be entitled to such indemnification unless (A) the
Indemnitee misrepresented or failed to disclose a material fact in making the
request for indemnification or in the Supporting Documentation or (B) such
indemnification is prohibited by law. The termination of any Proceeding
described in Section (a), or of any claim, issue or matter therein, by judgment,
order settlement or conviction, or upon a pleas of nolo contendere or its
equivalent, shall not, of itself, adversely affect the right of the Indemnitee
to indemnification or create a presumption that the Indemnitee did not act in
good faith and in a manner which the Indemnitee reasonably believed to be in or
not opposed to the best interests of the Corporation or, with respect to any
criminal Proceeding, that the Indemnitee had reasonable cause to believe that
the Indemnitee's conduct was unlawful.

         (4) Remedies of Indemnitee.

         (i) In the event that a determination is made pursuant to Section
(d)(2) or (3), that the Indemnitee is not entitled to indemnification under this
Paragraph 10, (A) the Indemnitee shall be entitled to seek an adjudication of
his entitlement to such indemnification either, at the Indemnitee's sole option,
in (x) an appropriate court of the State of Delaware or any other court of
competent jurisdiction or (y) an arbitration to be conducted by a single
arbitrator pursuant to the rules of the American Arbitration Association; (B)
any such judicial proceeding or arbitration shall be de novo and the Indemnitee
shall not be prejudiced by reason of such adverse determination; and (C) in any
such judicial proceeding or arbitration the Corporation shall have the burden of
proving that the Indemnitee is not entitled to indemnification under this
Paragraph 10.

         (ii) If a determination shall have been made or deemed to have been
made, pursuant to Section (d)(2) or (3), that the Indemnitee is entitled to
Indemnitee, the Corporation shall be obligated to pay the amounts constituting
such indemnification within five days after such determination has been made or
deemed to have been made and shall be conclusively bound by such determination
unless (A) the Indemnitee misrepresented or failed to disclose a material fact
in making the request for indemnification or in the Supporting Documentation or
(B) such indemnification or in the Supporting Documentation or (C) such
indemnification is prohibited by law. In the event that (x) advancement of
expenses if not timely made pursuant to Section (d)(l) or (y) payment of
indemnification is not made within five days after a determination of
entitlement to indemnification has been made or deemed to have been made
pursuant to Section (d)(2) or (3), the Indemnitee shall be entitled to seek
judicial enforcement of the Corporation's obligation to pay to the Indemnitee
such advancement of expenses or indemnification. Notwithstanding the foregoing,
the Corporation may bring an action, in an appropriate court in the State of
Delaware or any other court of competent jurisdiction, contesting the right of
the Indemnitee to receive indemnification hereunder due to the occurrence of an
event described in subclause (A) or (B) of this clause (ii) (a "Disqualifying
Event"); provided, however, that in any such action the Corporation shall have
the burden of proving the occurrence of such Disqualifying Event.

         (iii) The Corporation shall be precluded from asserting in any judicial
proceeding or arbitration commenced pursuant to this Section (d)(4) that the
procedures and presumptions of this Paragraph 10 are not valid, binding and
enforceable and shall stipulate in any such court or
<PAGE>   83
                                                                    Exhibit 23-A
                                                                     Page 6 of 7



before any such arbitrator that the Corporation is bound by all the provisions
of this Paragraph 10.

         (iv) In the event that the Indemnitee, pursuant to this Section (d)(4),
seeks a judicial adjudication of or an award in arbitration to enforce his
rights under, or to recover damages for breach of, this Paragraph 10, the
Indemnitee shall be entitled to recover from the Corporation, and shall be
indemnified by the Corporation against, any expenses actually and reasonably
incurred by the Indemnitee if the Indemnitee prevails in such judicial
adjudication or arbitration. If it shall be determined in such judicial
adjudication or arbitration that the Indemnitee is entitled to receive part but
not all of the indemnification or advancement of expenses sought, the expenses
incurred by the Indemnitee in connection with such judicial adjudication or
arbitration shall be prorated accordingly.

          (5) Definitions. For purposes of this Section (d):

         (i) "Change in Control" means (A) so long as the Public Utility Holding
Company Act of 1935 is in effect, any "company" becoming a "holding company" in
respect to the Corporation or any determination, by the Securities and Exchange
Commission that any "person" should be subject to the obligations, duties, and
liabilities if imposed by said Act by virtue or his, hers or its influence over
the management or policies of the Corporation, or (B) whether or not said Act is
in effect a change in control of the Corporation or a nature that would be
required to be reported in response to Item 6(e) of Schedule 14A of Regulation
14A promulgated under the Securities Exchange Act of 1934 (the "Act"), whether
or not the Corporation is then subject to such reporting requirement; provided
that, without limitation, such a change in control shall be deemed to have
occurred if (i) any "person" (as such term is used in Section 13(d) and 14(d) of
the Act) is or becomes the "beneficial owner" (as defined in Rule 13d-3 under
the Act), directly or indirectly, of securities of the Corporation representing
10% or more of the combined voting power of the Corporation's then outstanding
securities without the prior approval of at least two-thirds of the members of
the Board of Director in office immediately prior to such acquisition; (ii) the
Corporation is a party to a merger, consolidation, sale of assets or other
reorganization, or a proxy consent, as a consequence of which members of the
Board of Directors in office immediately prior to such transaction or event
constitute less than a majority of the Board of Directors thereafter; or (iii)
during any period of two consecutive years, individuals who at the beginning of
such period constituted the Board of Directors (including for this purpose any
new director whose election or nomination for election by the Corporation's
stockholders was approved by a vote of at least two-thirds of the directors then
still in office who were directors at the beginning of such period) cease for
any reason to constitute at least a majority of the Board of Directors.

         (ii) "Disinterested Director" means a director of the Corporation who
is not or was not a party to the Proceeding in respect of which indemnification
is sought by the Indemnitee.

         (iii) "Independent Counsel" means a law firm or a member of a law firm
that neither presently is, nor in the past five years has been, retained to the
representation: (A) the Corporation or the Indemnitee in any matter material to
either such party or (B) any other party to the proceeding giving rise to a
claim for indemnification under this Paragraph 10. Notwithstanding the
foregoing, the term "Independent Counsel" shall not include any person who,
under the applicable standards of professional conduct then prevailing under the
law of the
<PAGE>   84
                                                                    Exhibit 23-A
                                                                     Page 7 of 7



State of Delaware, would have a conflict of interest in representing either the
Corporation or the Indemnitee is an action to determine the Indemnitee's rights
under this Paragraph 10.

         (e) Serverability. If any provision or provisions of the Paragraph 10
shall be held to be invalid, illegal or unenforceable for any reason whatsoever:
(i) the validity, legality and enforceability of the remaining provision of this
Paragraph 10 (including, without limitation, all portions of any paragraph of
this Paragraph 10 containing any such provision held to be invalid, illegal or
unenforceable, that are not themselves invalid, illegal or unenforceable) shall
not in any way be affected or impaired thereby; and (ii) to the fullest extent
possible, the provisions of this Paragraph 10 (including, without limitation,
all portions of any paragraph of this Paragraph 10 containing any such provision
held to be invalid, illegal or unenforceable, that are not themselves invalid,
illegal or unenforceable) shall be construed so as to give effect to the intent
manifested by the provision held invalid, illegal or unenforceable.

         (f) Successor Laws, Regulations and Agencies. Reference herein to laws,
regulations or agencies shall be deemed to include all amendments thereof,
substitutions therefor and successors thereto.

         ELEVENTH. Meeting of the stockholders may be held within or without the
State of Delaware, as the by-laws may provide. The books of the Corporation may
be kept (subject to any provision contained in the statutes) outside the State
of Delaware at such place or places as may be designated from time to time by
the Board of Directors or in the by-laws of the Corporation. Elections of
directors need not be by written ballot unless the by-laws of the Corporation
shall so provide.

         TWELFTH. The Corporation reserves the right to amend, alter, change or
repeal any provision contained in this Certificate of Incorporation, in the
manner now or hereafter prescribed by statute, and all rights conferred upon
stockholders herein are granted subject to this reservation.

         I, THE UNDERSIGNED, being the incorporator hereinbefore named, for the
purpose of forming a corporation pursuant to the General Corporation Law of the
State of Delaware, do make this certificate, hereby declaring and certifying
that this is my act and deed and the facts herein stated are true, and

                                                                   Page 11 of 14


may otherwise be entitled, and the provisions of this Article VIII shall inure
to the benefit of the heirs and legal representatives of any person entitled to
indemnity under this Article VIII and shall be applicable to Proceedings
commenced or continuing after the adoption of this Article VIII, whether arising
from acts or omissions occurring before or after such adoption.

         (d) Advancement of Expenses; Procedures; Presumptions and Effect of
Certain Proceedings; Remedies. In furtherance but not in limitation of the
foregoing provisions, the following procedures, presumptions, and remedies shall
apply with respect to advancement of expenses and the right to indemnification
under this Article VIII:

         (1) Advance of Expenses. All reasonable expenses incurred by or on
behalf of the Indemnitee in connection with any Proceeding shall be advanced to
the Indemnitee by the Corporation within 20 days after the receipt by the
Corporation of a statement or statements from the Indemnitee requesting such
advance or advances from time to time, whether prior to or after final
disposition of such Proceeding. Such statement or statements shall reasonably
evidence the expenses incurred by the Indemnitee and, if required by law at the
time of such advance, shall include or be accompanied by an undertaking by or on
behalf of the Indemnitee to repay the amounts advanced if it should ultimately
be determined that the Indemnitee is not entitled to be indemnified against such
expenses pursuant to this Article VIII.

         (2) Procedure for Determination of Entitlement to Indemnification.

         (i) To obtain indemnification under this Article VIII, an Indemnitee
shall submit to the Secretary of the Corporation a written request, including
such documentation and information as is reasonably available to the Indemnitee
and reasonably necessary to determine whether and to what extent the Indemnitee
is entitled to indemnification (the "Supporting Documentation"). The
determination of the Indemnitee's entitlement to indemnification shall be made
not later than 60 days after receipt by the Corporation of the written request
for indemnification together with Supporting Documentation. The Secretary of the
Corporation shall advise the Board of Directors in writing, promptly upon
receipt of such a request for indemnification, that the Indemnitee has requested
indemnification.

         (ii) The Indemnitee's entitlement to indemnification under this Article
VIII shall be determined in one of the following ways: (A) by a majority vote of
the Disinterested Directors (as hereinafter defined), even if they constitute
less than a quorum of the Board of Directors; (B) by a written opinion of
Independent Counsel (as hereinafter defined) if (x) a Change of Control (as
hereinafter defined) shall have occurred and the Indemnitee so requests or (y) a
quorum of the Board of Directors consisting of Disinterested Directors is not
obtainable or, even if obtainable, a majority of such Disinterested Directors so
directs; (C) by the stockholders of the Corporation (but only if a majority of
the Disinterested Directors present the issue of entitlement to indemnification
to the stockholders for their determination); or (D) as provided in Section
(d)(3).

         (iii) In the event the determination of entitlement to indemnification
is to be made by Independent Counsel pursuant to Section (d)(2)(ii), a majority
of the Board of Directors shall select the Independent Counsel, but only an
Independent Counsel to which the Indemnitee does
<PAGE>   97
                                                                     Exhibit 1-B
                                                                   Page 12 of 14


not reasonably object; provided, however, that if a Change of Control shall have
occurred, the Indemnitee shall select such Independent Counsel, but only an
Independent Counsel to which the Board of Directors does not reasonably object.

         (iv) The only basis upon which a finding of no entitlement to
indemnification may be made is that indemnification is prohibited by law.

         (3) Presumptions and Effect of Certain Proceedings. Except as otherwise
expressly provided in this Article VIII, if a Change of Control shall have
occurred, the Indemnitee shall be presumed to be entitled to indemnification
under this Article VIII upon submission of a request for indemnification
together with the Supporting Documentation in accordance with Section (d)(2)(i),
and thereafter the Corporation shall have the burden of proof to overcome that
presumption in reaching a contrary determination. In any event, if the person or
persons empowered under Section (d)(2) to determine entitlement to
indemnification shall not have been appointed or shall not have made a
determination within 60 days after receipt by the Corporation of the request
therefor together with the Supporting Documentation, the Indemnitee shall be
deemed to be entitled to indemnification, and the Indemnitee shall be entitled
to such indemnification unless (A) the Indemnitee misrepresented or failed to
disclose a material fact in making the request for indemnification or in the
Supporting Documentation or (B) such indemnification is prohibited by law. The
termination of any Proceeding described in Section (a), or of any claim, issue,
or matter therein, by judgment, order, settlement, or conviction, or upon a plea
of nolo contendere or its equivalent, shall not of itself adversely affect the
right of the Indemnitee to indemnification or create a presumption that the
Indemnitee did not act in good faith and in a manner which the Indemnitee
reasonably believed to be in or not opposed to the best interests of the
Corporation or, with respect to any criminal Proceeding, that the Indemnitee had
reasonable cause to believe that the Indemnitee's conduct was unlawful.

         (4)      Remedies of Indemnitee.
         (i) In the event that a determination is made pursuant to Section
(d)(2) or (3) that the Indemnitee is not entitled to indemnification under this
Article VIII, (A) the Indemnitee shall be entitled to seek an adjudication of
his entitlement to such indemnification either, at the Indemnitee's sole option,
in (x) an appropriate court of the State of Delaware or any other court of
competent jurisdiction, or (y) an arbitration to be conducted by a single
arbitrator pursuant to the rules of the American Arbitration Association; (B)
any such judicial proceeding or arbitration shall be de novo and the Indemnitee
shall not be prejudiced by reason of such adverse determination; and (C) in any
such judicial proceeding or arbitration, the Corporation shall have the burden
of proving that the Indemnitee is not entitled to indemnification under this
Article VIII.

         (ii) If pursuant to Section (d)(2) or (3) a determination shall have
been made or deemed to have been made that the Indemnitee is entitled to
indemnification, the Corporation shall be obligated to pay the amounts
constituting such indemnification within five days after such determination has
been made or is deemed to have been made and shall be conclusively bound by such
determination unless (A) the Indemnitee misrepresented or failed to disclose a
material fact in making the request for indemnification or in the Supporting
Documentation, or
<PAGE>   98
                                                                     Exhibit 1-B
                                                                   Page 13 of 14


(B) such indemnification is prohibited by law. In the event that (X) advancement
of expenses is not timely made pursuant to Section (d)(l), or (Y) payment of
indemnification is not made within five days after a determination of
entitlement to indemnification has been made or deemed to have been made
pursuant to Section (d)(2) or (3), the Indemnitee shall be entitled to seek
judicial enforcement of the Corporation's obligation to pay to the Indemnitee
such advancement of expenses or indemnification. Notwithstanding the foregoing,
the Corporation may bring an action in an appropriate court in the State of
Delaware or any other court of competent jurisdiction, contesting the right of
the Indemnitee to receive indemnification hereunder due to the occurrence of an
event described in subclause (A) or (B) of this clause (ii) (a "Disqualifying
Event"); provided, however, that in any such action the Corporation shall have
the burden of proving the occurrence of such Disqualifying Event.

         (iii) The Corporation shall be precluded from asserting in any judicial
proceeding or arbitration commenced pursuant to this Section (d)(4) that the
procedures and presumptions of this Article VIII are not valid, binding, and
enforceable and shall stipulate in any such court or before any such arbitrator
that the Corporation is bound by all the provisions of this Article VIII.

         (iv) In the event that pursuant to this Section (d)(4) the Indemnitee
seeks a judicial adjudication of or an award in arbitration to enforce his
rights under, or to recover damages for breach of this Article VIII, the
Indemnitee shall be entitled to recover from the Corporation, and shall be
indemnified by the Corporation against, any expenses actually and reasonably
incurred by the Indemnitee if the Indemnitee prevails in such judicial
adjudication or arbitration. If it shall be determined in such judicial
adjudication or arbitration that the Indemnitee is entitled to receive part but
not all of the indemnification or advancement of expenses sought, the expenses
incurred by the Indemnitee in connection with such judicial adjudication or
arbitration shall be prorated accordingly.

         (5) Definitions. For purposes of this Section (d):
         (i) "Change in Control" means (A) so long as the Public Utility Holding
Company Act of 1935 is in effect, any "company" becoming a "holding company" in
respect to the Corporation or any determination by the Securities and Exchange
Commission that any "person" should be subject to the obligations, duties, and
liabilities if imposed by said Act by virtue or his, hers or its influence over
the management or policies of the Corporation, or (B) whether or not said Act is
in effect, a change in control of the Corporation of a nature that would be
required to be reported in response to Item 6(e) of Schedule 14A of Regulation
14A promulgated under the Securities Exchange Act of 1934 (the "Act"), whether
or not the Corporation is then subject to such reporting requirement; provided
that, without limitation, such a change in control shall be deemed to have
occurred if (i) any "person" (as such term is used in Section 13(d) and 14(d) of
the Act) is or becomes the "beneficial owner" (as defined in Rule 13d-3 under
the Act), directly or indirectly, of securities of the Corporation representing
10 percent or more of the combined voting power of the Corporation's then
outstanding securities without the prior approval of at least two-thirds of the
members of the Board of Directors
<PAGE>   99
                                                                     Exhibit 1-B
                                                                   Page 14 of 14


in office immediately prior to such acquisition; (ii) the Corporation is a party
to a merger, consolidation, sale of assets or other reorganization, or a proxy
contest, as a consequence of which members of the Board of Directors in office
immediately prior to such transaction or event constitute less than a majority
of the Board of Directors thereafter; or (iii) during any period of two
consecutive years, individuals who at the beginning of such period constituted
the Board of Directors (including for this purpose any new director whose
election or nomination for election by the Corporation's stockholders was
approved by a vote of at least two-thirds of the directors then still in office
who were directors at the beginning of such period) cease for any reason to
constitute at least a majority of the Board of Directors.

         (ii) "Disinterested Director" means a director of the Corporation who
is not or was not a party to the Proceeding in respect of which indemnification
is sought by the Indemnitee.

         (iii) "Independent Counsel" means a law firm or a member of a law firm
that neither presently is, nor in the past five years has been, retained to
represent: (A) the Corporation or the Indemnitee in any matter material to
either such party, or (B) any other party to the Proceeding giving rise to a
claim for indemnification under this Article VIII. Notwithstanding the
foregoing, the term "Independent Counsel" shall not include any person who,
under the applicable standards of professional conduct then prevailing under the
law of the State of Delaware, would have a conflict of interest in representing
either the Corporation or the Indemnitee in an action to determine the
Indemnitee's rights under this Article VIII.

         (e) Severability. If any provision or provisions of this Article VIII
shall be held to be invalid, illegal or unenforceable for any reason whatsoever:
(i) the validity, legality, and enforceability of the remaining provisions of
this Article VIII (including, without limitation, all portions of any paragraph
of this Article VIII containing any such provision held to be invalid, illegal,
or unenforceable, that are not themselves invalid, illegal, or unenforceable)
shall not in any way be affected or impaired thereby; and (ii) to the fullest
extent possible, the provisions of this Article VIII (including, without
limitation, all portions of any paragraph of this Article VIII containing any
such provision held to be invalid, illegal, or unenforceable that are not
themselves invalid, illegal, or unenforceable) shall be construed so as to give
effect to the intent manifested by the provision held invalid, illegal, or
unenforceable.

         (f) Successor Laws, Regulations, and Agencies. Reference herein to
laws, regulations, or agencies shall be deemed to include all amendments
thereof, substitutions therefor, and successors thereto.

                                   ARTICLE IX

                                   AMENDMENTS

Directors or at any special meeting of the stockholders or of the Board of
Directors if notice of such alteration, amendment, repeal, or adoption of new
Bylaws be contained in the notice of such special meeting.

consent thereto in writing, and the writing or writings are filed with the
minutes of proceedings of the Board or committee.

         Section 10. Unless otherwise restricted by the Certificate of
Incorporation or these Bylaws, members of the Board of Directors, or any
committee designated by the Board of Directors, may participate in a meeting of
the Board of Directors, or any committee, by means of conference telephone or

the meeting can hear each other, and such participation in a meeting shall
constitute presence in person at the meeting.

                             COMMITTEES OF DIRECTORS
         Section 11. The Board of Directors may, by resolution passed by a
majority of the whole Board, designate one or more committees, each committee to

designate one or more directors as alternate members of any committee, who may
replace any absent or disqualified member at any meeting of the committee. In
the absence or disqualification of a member of a committee, the member or
members thereof present at any meeting and not disqualified from voting, whether
or not he or they constitute a quorum, may unanimously appoint another member of
the Board of Directors to act at the meeting in the place of any such absent or
disqualified member. Any such committee, to the extent provided in the
resolution of the Board of Directors, shall have and may exercise all the powers
and authority of the Board of Directors in the management of the business and
affairs
<PAGE>   104
                                                                     Exhibit 2-B

to all papers which may require it; but no such committee shall have the power
or authority in reference to amending the Certificate of Incorporation, adopting
an agreement of merger or consolidation, recommending to the stockholders the
sale, lease, or exchange of all or substantially all of the Corporation's
property and assets, recommending to the stockholders a dissolution of the

salary as director. No such payment shall preclude any director from serving the
Corporation in any other capacity and receiving compensation therefor. Members
of special or standing committees may be allowed like compensation for attending

                                   ARTICLE VII

                               GENERAL PROVISIONS

                                  ARTICLE VIII

                                 INDEMNIFICATION
         (a) Right to Indemnification. The Corporation shall to the fullest
extent permitted by applicable law as then in effect indemnify any person (the
"Indemnitee") who was or is involved in any manner (including, without
limitation, as a party or a witness) or is threatened to be made so involved in
any threatened, pending or completed investigation, claim, action, suit or
proceeding, whether civil, criminal, administrative, or investigative (including
without limitation, any action, suit, or proceeding by or in the right of the
Corporation to procure a judgment in its favor) (a "Proceeding") by reason of
the fact that such person is or was a director, officer, employee, or agent of
the Corporation, or is or was serving at the request of the Corporation as a
director, officer, employee, or agent of another Corporation, partnership, joint
venture, trust, or other enterprise (including, without limitation, any employee
benefit plan) against all expenses (including attorneys' fees), judgments,
fines, and amounts paid in settlement actually and reasonably incurred by such
person in connection with such Proceeding. Such indemnification shall be a
contract right and shall include the right to receive payment of any expenses
incurred by the Indemnitee in connection with such Proceeding in advance of its
final disposition, consistent with the provisions of applicable law as then in
effect.

         (b) Insurance, Contracts, and Funding. The Corporation may purchase and
maintain insurance to protect itself and any indemnitee against any expenses,
judgments, fines, and amounts paid in settlement as specified in Section (a) of
this Article VIII or incurred by an
<PAGE>   110
                                                                     Exhibit 2-B
                                                                   Page 11 of 15


Indemnitee in connection with any proceeding referred to in Section (a) of this
Article VIII, to the fullest extent permitted by applicable law as then in
effect. The Corporation may enter into contracts with any director, officer,
employee, or agent of the Corporation or use other means in furtherance of the
provisions of this Article VIII to ensure the payment of such amounts as may be
necessary to effect indemnification as provided in this Article VIII.

         (c) Indemnification; Not Exclusive Right. The right of indemnification
provided in this Article VIII shall not be exclusive of any other rights to
which those seeking indemnification may otherwise be entitled, and the
provisions of this Article VIII shall inure to the benefit of the heirs and
legal representatives of any person entitled to indemnity under this Article
VIII and shall be applicable to Proceedings commenced or continuing after the
adoption of this Article VIII, whether arising from acts or omissions occurring
before or after such adoption.

         (d) Advancement of Expenses; Procedures; Presumptions and Effect of
Certain Proceedings; Remedies. In furtherance but not in limitation of the
foregoing provisions, the following procedures, presumptions, and remedies shall
apply with respect to advancement of expenses and the right to indemnification
under this Article VIII:

         (1) Advance of Expenses. All reasonable expenses incurred by or on
behalf of the Indemnitee in connection with any Proceeding shall be advanced to
the Indemnitee by the Corporation within 20 days after the receipt by the
Corporation of a statement or statements from the Indemnitee requesting such
advance or advances from time to time, whether prior to or after final
disposition of such Proceeding. Such statement or statements shall reasonably
evidence the expenses incurred by the Indemnitee and, if required by law at the
time of such advance, shall include or be accompanied by an undertaking by or on
behalf of the Indemnitee to repay the amounts advanced if it should ultimately
be determined that the Indemnitee is not entitled to be indemnified against such
expenses pursuant to this Article VIII.

         (2) Procedure for Determination of Entitlement to Indemnification.
         (i) To obtain indemnification under this Article VIII, an Indemnitee
shall submit to the Secretary of the Corporation a written request, including
such documentation and information as is reasonably available to the Indemnitee
and reasonably necessary to determine whether and to what extent the Indemnitee
is entitled to indemnification (the "Supporting Documentation"). The
determination of the Indemnitee's entitlement to indemnification shall be made
not later than 60 days after receipt by the Corporation of the written request
for indemnification together with Supporting Documentation. The Secretary of the
Corporation shall advise the Board of Directors in writing, promptly upon
receipt of such a request for indemnification, that the Indemnitee has requested
indemnification.

         (ii) The Indemnitee's entitlement to indemnification under this Article
VIII shall be determined in one of the following ways: (A) by a majority vote of
the Disinterested Directors (as hereinafter defined), even if they constitute
less than a quorum of the Board of Directors; (B) by a written opinion of
Independent Counsel (as hereinafter defined) if (x) a Change of Control (as
hereinafter defined) shall have occurred and the Indemnitee so requests or (y) a
quorum of the Board of Directors consisting of Disinterested Directors is not
obtainable or, even if obtainable, a
<PAGE>   111
                                                                     Exhibit 2-B
                                                                   Page 12 of 15


majority of such Disinterested Directors so directs; (C) by the stockholders of
the Corporation (but only if a majority of the Disinterested Directors present
the issue of entitlement to indemnification to the stockholders for their
determination); or (D) as provided in Section (d)(3).

         (iii) In the event the determination of entitlement to indemnification
is to be made by Independent Counsel pursuant to Section (d)(2)(ii), a majority
of the Board of Directors shall select the Independent Counsel, but only an
Independent Counsel to which the Indemnitee does not reasonably object;
provided, however, that if a Change of Control shall have occurred, the
Indemnitee shall select such Independent Counsel, but only an Independent
Counsel to which the Board of Directors does not reasonably object.

         (iv) The only basis upon which a finding of no entitlement to
indemnification may be made is that indemnification is prohibited by law.

         (3) Presumptions and Effect of Certain Proceedings. Except as otherwise
expressly provided in this Article VIII, if a Change of Control shall have
occurred, the Indemnitee shall be presumed to be entitled to indemnification
under this Article VIII upon submission of a request for indemnification
together with the Supporting Documentation in accordance with Section (d)(2)(i),
and thereafter the Corporation shall have the burden of proof to overcome that
presumption in reaching a contrary determination. In any event, if the person or
persons empowered under Section (d)(2) to determine entitlement to
indemnification shall not have been appointed or shall not have made a
determination within 60 days after receipt by the Corporation of the request
therefor together with the Supporting Documentation, the Indemnitee shall be
deemed to be entitled to indemnification, and the Indemnitee shall be entitled
to such indemnification unless (A) the Indemnitee misrepresented or failed to
disclose a material fact in making the request for indemnification or in the
Supporting Documentation or (B) such indemnification is prohibited by law. The
termination of any Proceeding described in Section (a), or of any claim, issue,
or matter therein, by judgment, order, settlement, or conviction, or upon a plea
of nolo contendere or its equivalent, shall not of itself adversely affect the
right of the Indemnitee to indemnification or create a presumption that the
Indemnitee did not act in good faith and in a manner which the Indemnitee
reasonably believed to be in or not opposed to the best interests of the
Corporation or, with respect to any criminal Proceeding, that the Indemnitee had
reasonable cause to believe that the Indemnitee's conduct was unlawful.

         (4)      Remedies of Indemnitee.
         (i) In the event that a determination is made pursuant to Section
(d)(2) or (3) that the Indemnitee is not entitled to indemnification under this
Article VIII, (A) the Indemnitee shall be entitled to seek an adjudication of
his entitlement to such indemnification either, at the Indemnitee's sole option,
in (x) an appropriate court of the State of Delaware or any other court of
competent jurisdiction, or (y) an arbitration to be conducted by a single
arbitrator pursuant to the rules of the American Arbitration Association; (B)
any such judicial proceeding or arbitration shall be de novo and the Indemnitee
shall not be prejudiced by reason of such adverse determination; and (C) in any
such judicial proceeding or arbitration, the Corporation shall have
<PAGE>   112
                                                                     Exhibit 2-B
                                                                   Page 13 of 15


the burden of proving that the Indemnitee is not entitled to indemnification
under this Article VIII.

         (ii) If pursuant to Section (d)(2) or (3) a determination shall have
been made or deemed to have been made that the Indemnitee is entitled to
indemnification, the Corporation shall be obligated to pay the amounts
constituting such indemnification within five days after such determination has
been made or is deemed to have been made and shall be conclusively bound by such
determination unless (A) the Indemnitee misrepresented or failed to disclose a
material fact in making the request for indemnification or in the Supporting
Documentation, or (B) such indemnification is prohibited by law. In the event
that (X) advancement of expenses is not timely made pursuant to Section (d)(l),
or (Y) payment of indemnification is not made within five days after a
determination of entitlement to indemnification has been made or deemed to have
been made pursuant to Section (d)(2) or (3), the Indemnitee shall be entitled to
seek judicial enforcement of the Corporation's obligation to pay to the
Indemnitee such advancement of expenses or indemnification. Notwithstanding the
foregoing, the Corporation may bring an action in an appropriate court in the
State of Delaware or any other court of competent jurisdiction, contesting the
right of the Indemnitee to receive indemnification hereunder due to the
occurrence of an event described in subclause (A) or (B) of this clause (ii) (a
"Disqualifying Event"); provided, however, that in any such action the
Corporation shall have the burden of proving the occurrence of such
Disqualifying Event.

         (iii) The Corporation shall be precluded from asserting in any judicial
proceeding or arbitration commenced pursuant to this Section (d)(4) that the
procedures and presumptions of this Article VIII are not valid, binding, and
enforceable and shall stipulate in any such court or before any such arbitrator
that the Corporation is bound by all the provisions of this Article VIII.

         (iv) In the event that pursuant to this Section (d)(4) the Indemnitee
seeks a judicial adjudication of or an award in arbitration to enforce his
rights under, or to recover damages for breach of this Article VIII, the
Indemnitee shall be entitled to recover from the Corporation, and shall be
indemnified by the Corporation against, any expenses actually and reasonably
incurred by the Indemnitee if the Indemnitee prevails in such judicial
adjudication or arbitration. If it shall be determined in such judicial
adjudication or arbitration that the Indemnitee is entitled to receive part but
not all of the indemnification or advancement of expenses sought, the expenses
incurred by the Indemnitee in connection with such judicial adjudication or
arbitration shall be prorated accordingly.

         (5) Definitions. For purposes of this Section (d):
         (i) "Change in Control" means (A) so long as the Public Utility Holding
Company Act of 1935 is in effect, any "company" becoming a "holding company" in
respect to the Corporation or any determination by the Securities and Exchange
Commission that any "person" should be subject to the obligations, duties, and
liabilities if imposed by said Act by virtue or his, hers or its influence over
the management or policies of the Corporation, or (B) whether or not said Act is
in effect, a change in control of the Corporation of a nature that would be
required to be reported in response to Item 6(e) of Schedule 14A of Regulation
14A promulgated under the
<PAGE>   113
                                                                     Exhibit 2-B
                                                                   Page 14 of 15


Securities Exchange Act of 1934 (the "Act"), whether or not the Corporation is
then subject to such reporting requirement; provided that, without limitation,
such a change in control shall be deemed to have occurred if (i) any "person"
(as such term is used in Section 13(d) and 14(d) of the Act) is or becomes the
"beneficial owner" (as defined in Rule 13d-3 under the Act), directly or
indirectly, of securities of the Corporation representing 10 percent or more of
the combined voting power of the Corporation's then outstanding securities
without the prior approval of at least two-thirds of the members of the Board of
Directors in office immediately prior to such acquisition; (ii) the Corporation
is a party to a merger, consolidation, sale of assets or other reorganization,
or a proxy contest, as a consequence of which members of the Board of Directors
in office immediately prior to such transaction or event constitute less than a
majority of the Board of Directors thereafter; or (iii) during any period of two
consecutive years, individuals who at the beginning of such period constituted
the Board of Directors (including for this purpose any new director whose
election or nomination for election by the Corporation's stockholders was
approved by a vote of at least two-thirds of the directors then still in office
who were directors at the beginning of such period) cease for any reason to
constitute at least a majority of the Board of Directors.

         (ii) "Disinterested Director" means a director of the Corporation who
is not or was not a party to the Proceeding in respect of which indemnification
is sought by the Indemnitee.

         (iii) "Independent Counsel" means a law firm or a member of a law firm
that neither presently is, nor in the past five years has been, retained to
represent: (A) the Corporation or the Indemnitee in any matter material to
either such party, or (B) any other party to the Proceeding giving rise to a
claim for indemnification under this Article VIII. Notwithstanding the
foregoing, the term "Independent Counsel" shall not include any person who,
under the applicable standards of professional conduct then prevailing under the
law of the State of Delaware, would have a conflict of interest in representing
either the Corporation or the Indemnitee in an action to determine the
Indemnitee's rights under this Article VIII.

         (e) Severability. If any provision or provisions of this Article VIII
shall be held to be invalid, illegal or unenforceable for any reason whatsoever:
(i) the validity, legality, and enforceability of the remaining provisions of
this Article VIII (including, without limitation, all portions of any paragraph
of this Article VIII containing any such provision held to be invalid, illegal,
or unenforceable, that are not themselves invalid, illegal, or unenforceable)
shall not in any way be affected or impaired thereby; and (ii) to the fullest
extent possible, the provisions of this Article VIII (including, without
limitation, all portions of any paragraph of this Article VIII containing any
such provision held to be invalid, illegal, or unenforceable that are not
themselves invalid, illegal, or unenforceable) shall be construed so as to give
effect to the intent manifested by the provision held invalid, illegal, or
unenforceable.

         (f) Successor Laws, Regulations, and Agencies. Reference herein to
laws, regulations, or agencies shall be deemed to include all amendments
thereof, substitutions therefor, and successors thereto.

disbursements, and shall render to the president and the Board of Directors, at
its regular meetings, or when the Board of Directors so requires, an account of
all his/their transactions as treasurer/assistant treasurer.

         Section 13. If required by the Board of Directors, the treasurer or an
assistant treasurer shall give the Corporation a bond (which shall be renewed
every six years) in such sum and with such surety or sureties as shall be
satisfactory to the Board of Directors for the faithful performance of the
duties of their offices and for the restoration to the Corporation, in case of
their death, resignation, retirement or removal from office, of all books,
papers, vouchers, money and other property of whatever kind in their possession
or under their control belonging to the Corporation.

         Section 14. The assistant treasurer, or if there shall be more than
one, the assistant treasurers in the order determined by the Board of Directors
(or if there be no such determination,

then in the order of their election), shall, in the absence of the treasurer or
in the event of his inability or refusal to act, perform the duties and exercise
the powers of the treasurer and shall perform such other duties and have such
other powers as the Board of Directors may from time to time prescribe.

                     THE CONTROLLER AND ASSISTANT CONTROLLER
         Section 15. The controller, or as directed by the Board of Directors,
one or more assistant controllers, shall maintain adequate records of all

financial results of operations are properly recorded and that adequate audits
thereof are currently and regularly made; and, in conjunction with other
officers, initiate and enforce measures and procedures whereby the business of
the Corporation shall be conducted with the maximum safety, efficiency, and
economy. The controller or an assistant controller shall report to the president
and/or the Board of Directors at its regular meetings on the financial results
of the Corporation's operations. The controller shall have such other duties as
the Board of Directors may designate from time to time.

president or the vice president, or the secretary or an assistant secretary of
the Corporation, certifying the number of shares owned by him in the
Corporation.

         Section 2. Any of or all the signatures on the certificate may be
facsimile. In case any officer, transfer agent or registrar who has signed or
whose facsimile signature has been placed upon a certificate shall have ceased
to be such officer, transfer agent or registrar before such certificate is
issued, it may be issued by the Corporation with the same effect as if he were
such officer, transfer agent or registrar at the date of issue.

         Section 3. The Board of Directors may direct a new certificate or
certificates to be issued in place of any certificate or certificates
theretofore issued by the Corporation alleged to have been lost, stolen or
destroyed, upon the making of an affidavit of that fact by the person claiming
the certificate of stock to be lost, stolen or destroyed. When authorizing such
issue of a new certificate or certificates, the Board of Directors may, in its
discretion and as a condition precedent to the issuance thereof, require the
owner of such lost, stolen or destroyed certificate or certificates, or his
legal representative, to advertise the same in such manner as it shall require
and/or to give the Corporation a bond in such sum as it may direct as indemnity
against any claim that may be made against the Corporation with respect to the
certificate alleged to have been lost, stolen or destroyed.

respect of any change, conversion or exchange of stock or for the purpose of any
other lawful action, the Board of Directors may fix, in advance, a record date,

meeting.

                             REGISTERED STOCKHOLDERS
         Section 6. The Corporation shall be entitled to recognize the exclusive
right of a person registered on its books as the owner of shares to receive
dividends, and to vote as such owner, and to hold liable for calls and
assessments a person registered on its books as the owner of shares, and shall
not be bound to recognize any equitable or other claim to or interest in such

express or other notice thereof, except as otherwise provided by the laws of
Delaware.

directors from time to time, in their absolute discretion, think proper as a
reserve or reserves to meet contingencies, or for equalizing dividends, or for
repairing or maintaining any property of the Corporation, or for such other
purpose as the directors shall think conducive to the interest of the
Corporation, and the directors may modify or abolish any such reserve in the

Directors, or unless required by law, be signed by any two of the following
officers: the President, any Vice President, the Secretary, any Assistant
Secretary, the Treasurer, or any Assistant Treasurer; provided that in every

not be officers or employees of the Corporation to give in the name of the
Corporation telephonic, telegraphic, or electronic transfer instructions for the
payment of money, which may, with respect to routine items, include instructions
as to the amount to be transferred, to any bank, pursuant to previously issued
written orders, signed by officers of the Corporation or by any employee of the
Corporation so designated by the Board of Directors of the Corporation in any
manner provided above, which designate the recipients of such amounts and which
identify what shall be treated as routine items.

                                  ARTICLE VIII

                                 INDEMNIFICATION
         (a) Right to Indemnification. The Corporation shall to the fullest
extent permitted by applicable law as then in effect indemnify any person (the
"Indemnitee") who was or is involved in any manner (including, without
limitation, as a party or a witness) or is threatened to be made so involved in
any threatened, pending or completed investigation, claim, action, suit or
proceeding, whether civil, criminal, administrative, or investigative (including
without limitation,
<PAGE>   125
                                                                     Exhibit 3-B
                                                                   Page 11 of 15


any action, suit, or proceeding by or in the right of the Corporation to procure
a judgment in its favor) (a "Proceeding") by reason of the fact that such person
is or was a director, officer, employee, or agent of the Corporation, or is or
was serving at the request of the Corporation as a director, officer, employee,
or agent of another Corporation, partnership, joint venture, trust, or other
enterprise (including, without limitation, any employee benefit plan) against
all expenses (including attorneys' fees), judgments, fines, and amounts paid in
settlement actually and reasonably incurred by such person in connection with
such Proceeding. Such indemnification shall be a contract right and shall
include the right to receive payment of any expenses incurred by the Indemnitee
in connection with such Proceeding in advance of its final disposition,
consistent with the provisions of applicable law as then in effect.

         (b) Insurance, Contracts, and Funding. The Corporation may purchase and
maintain insurance to protect itself and any indemnitee against any expenses,
judgments, fines, and amounts paid in settlement as specified in Section (a) of
this Article VIII or incurred by an Indemnitee in connection with any proceeding
referred to in Section (a) of this Article VIII, to the fullest extent permitted
by applicable law as then in effect. The Corporation may enter into contracts
with any director, officer, employee, or agent of the Corporation or use other
means in furtherance of the provisions of this Article VIII to ensure the
payment of such amounts as may be necessary to effect indemnification as
provided in this Article VIII.

         (c) Indemnification; Not Exclusive Right. The right of indemnification
provided in this Article VIII shall not be exclusive of any other rights to
which those seeking indemnification may otherwise be entitled, and the
provisions of this Article VIII shall inure to the benefit of the heirs and
legal representatives of any person entitled to indemnity under this Article
VIII and shall be applicable to Proceedings commenced or continuing after the
adoption of this Article VIII, whether arising from acts or omissions occurring
before or after such adoption.

         (d) Advancement of Expenses; Procedures; Presumptions and Effect of
Certain Proceedings; Remedies. In furtherance but not in limitation of the
foregoing provisions, the following procedures, presumptions, and remedies shall
apply with respect to advancement of expenses and the right to indemnification
under this Article VIII:

         (1) Advance of Expenses. All reasonable expenses incurred by or on
behalf of the Indemnitee in connection with any Proceeding shall be advanced to
the Indemnitee by the Corporation within 20 days after the receipt by the
Corporation of a statement or statements from the Indemnitee requesting such
advance or advances from time to time, whether prior to or after final
disposition of such Proceeding. Such statement or statements shall reasonably
evidence the expenses incurred by the Indemnitee and, if required by law at the
time of such advance, shall include or be accompanied by an undertaking by or on
behalf of the Indemnitee to repay the amounts advanced if it should ultimately
be determined that the Indemnitee is not entitled to be indemnified against such
expenses pursuant to this Article VIII.

                                                                   Page 12 of 15


         (2) Procedure for Determination of Entitlement to Indemnification.
         (i) To obtain indemnification under this Article VIII, an Indemnitee
shall submit to the Secretary of the Corporation a written request, including
such documentation and information as is reasonably available to the Indemnitee
and reasonably necessary to determine whether and to what extent the Indemnitee
is entitled to indemnification (the "Supporting Documentation"). The
determination of the Indemnitee's entitlement to indemnification shall be made
not later than 60 days after receipt by the Corporation of the written request
for indemnification together with Supporting Documentation. The Secretary of the
Corporation shall advise the Board of Directors in writing, promptly upon
receipt of such a request for indemnification, that the Indemnitee has requested
indemnification.

         (ii) The Indemnitee's entitlement to indemnification under this Article
VIII shall be determined in one of the following ways: (A) by a majority vote of
the Disinterested Directors (as hereinafter defined), even if they constitute
less than a quorum of the Board of Directors; (B) by a written opinion of
Independent Counsel (as hereinafter defined) if (x) a Change of Control (as
hereinafter defined) shall have occurred and the Indemnitee so requests or (y) a
quorum of the Board of Directors consisting of Disinterested Directors is not
obtainable or, even if obtainable, a majority of such Disinterested Directors so
directs; (C) by the stockholders of the Corporation (but only if a majority of
the Disinterested Directors present the issue of entitlement to indemnification
to the stockholders for their determination); or (D) as provided in Section
(d)(3).

         (iii) In the event the determination of entitlement to indemnification
is to be made by Independent Counsel pursuant to Section (d)(2)(ii), a majority
of the Board of Directors shall select the Independent Counsel, but only an
Independent Counsel to which the Indemnitee does not reasonably object;
provided, however, that if a Change of Control shall have occurred, the
Indemnitee shall select such Independent Counsel, but only an Independent
Counsel to which the Board of Directors does not reasonably object.

         (iv) The only basis upon which a finding of no entitlement to
indemnification may be made is that indemnification is prohibited by law.

         (3) Presumptions and Effect of Certain Proceedings. Except as otherwise
expressly provided in this Article VIII, if a Change of Control shall have
occurred, the Indemnitee shall be presumed to be entitled to indemnification
under this Article VIII upon submission of a request for indemnification
together with the Supporting Documentation in accordance with Section (d)(2)(i),
and thereafter the Corporation shall have the burden of proof to overcome that
presumption in reaching a contrary determination. In any event, if the person or
persons empowered under Section (d)(2) to determine entitlement to
indemnification shall not have been appointed or shall not have made a
determination within 60 days after receipt by the Corporation of the request
therefor together with the Supporting Documentation, the Indemnitee shall be
deemed to be entitled to indemnification, and the Indemnitee shall be entitled
to such indemnification unless (A) the Indemnitee misrepresented or failed to
disclose a material fact in making the request for indemnification or in the
Supporting Documentation or (B) such
<PAGE>   127
                                                                     Exhibit 3-B
                                                                   Page 13 of 15


indemnification is prohibited by law. The termination of any Proceeding
described in Section (a), or of any claim, issue, or matter therein, by
judgment, order, settlement, or conviction, or upon a plea of nolo contendere or
its equivalent, shall not of itself adversely affect the right of the Indemnitee
to indemnification or create a presumption that the Indemnitee did not act in
good faith and in a manner which the Indemnitee reasonably believed to be in or
not opposed to the best interests of the Corporation or, with respect to any
criminal Proceeding, that the Indemnitee had reasonable cause to believe that
the Indemnitee's conduct was unlawful.

         (4)      Remedies of Indemnitee.
         (i) In the event that a determination is made pursuant to Section
(d)(2) or (3) that the Indemnitee is not entitled to indemnification under this
Article VIII, (A) the Indemnitee shall be entitled to seek an adjudication of
his entitlement to such indemnification either, at the Indemnitee's sole option,
in (x) an appropriate court of the State of Delaware or any other court of
competent jurisdiction, or (y) an arbitration to be conducted by a single
arbitrator pursuant to the rules of the American Arbitration Association; (B)
any such judicial proceeding or arbitration shall be de novo and the Indemnitee
shall not be prejudiced by reason of such adverse determination; and (C) in any
such judicial proceeding or arbitration, the Corporation shall have the burden
of proving that the Indemnitee is not entitled to indemnification under this
Article VIII.

         (ii) If pursuant to Section (d)(2) or (3) a determination shall have
been made or deemed to have been made that the Indemnitee is entitled to
indemnification, the Corporation shall be obligated to pay the amounts
constituting such indemnification within five days after such determination has
been made or is deemed to have been made and shall be conclusively bound by such
determination unless (A) the Indemnitee misrepresented or failed to disclose a
material fact in making the request for indemnification or in the Supporting
Documentation, or (B) such indemnification is prohibited by law. In the event
that (X) advancement of expenses is not timely made pursuant to Section (d)(l),
or (Y) payment of indemnification is not made within five days after a
determination of entitlement to indemnification has been made or deemed to have
been made pursuant to Section (d)(2) or (3), the Indemnitee shall be entitled to
seek judicial enforcement of the Corporation's obligation to pay to the
Indemnitee such advancement of expenses or indemnification. Notwithstanding the
foregoing, the Corporation may bring an action in an appropriate court in the
State of Delaware or any other court of competent jurisdiction, contesting the
right of the Indemnitee to receive indemnification hereunder due to the
occurrence of an event described in subclause (A) or (B) of this clause (ii) (a
"Disqualifying Event"); provided, however, that in any such action the
Corporation shall have the burden of proving the occurrence of such
Disqualifying Event.

         (iii) The Corporation shall be precluded from asserting in any judicial
proceeding or arbitration commenced pursuant to this Section (d)(4) that the
procedures and presumptions of this Article VIII are not valid, binding, and
enforceable and shall stipulate in any such court or before any such arbitrator
that the Corporation is bound by all the provisions of this Article VIII.
<PAGE>   128
                                                                     Exhibit 3-B
                                                                   Page 14 of 15


         (iv) In the event that pursuant to this Section (d)(4) the Indemnitee
seeks a judicial adjudication of or an award in arbitration to enforce his
rights under, or to recover damages for breach of this Article VIII, the
Indemnitee shall be entitled to recover from the Corporation, and shall be
indemnified by the Corporation against, any expenses actually and reasonably
incurred by the Indemnitee if the Indemnitee prevails in such judicial
adjudication or arbitration. If it shall be determined in such judicial
adjudication or arbitration that the Indemnitee is entitled to receive part but
not all of the indemnification or advancement of expenses sought, the expenses
incurred by the Indemnitee in connection with such judicial adjudication or
arbitration shall be prorated accordingly.

         (5) Definitions. For purposes of this Section (d):
         (i) "Change in Control" means (A) so long as the Public Utility Holding
Company Act of 1935 is in effect, any "company" becoming a "holding company" in
respect to the Corporation or any determination by the Securities and Exchange
Commission that any "person" should be subject to the obligations, duties, and
liabilities if imposed by said Act by virtue or his, hers or its influence over
the management or policies of the Corporation, or (B) whether or not said Act is
in effect, a change in control of the Corporation of a nature that would be
required to be reported in response to Item 6(e) of Schedule 14A of Regulation
14A promulgated under the Securities Exchange Act of 1934 (the "Act"), whether
or not the Corporation is then subject to such reporting requirement; provided
that, without limitation, such a change in control shall be deemed to have
occurred if (i) any "person" (as such term is used in Section 13(d) and 14(d) of
the Act) is or becomes the "beneficial owner" (as defined in Rule 13d-3 under
the Act), directly or indirectly, of securities of the Corporation representing
10 percent or more of the combined voting power of the Corporation's then
outstanding securities without the prior approval of at least two-thirds of the
members of the Board of Directors in office immediately prior to such
acquisition; (ii) the Corporation is a party to a merger, consolidation, sale of
assets or other reorganization, or a proxy contest, as a consequence of which
members of the Board of Directors in office immediately prior to such
transaction or event constitute less than a majority of the Board of Directors
thereafter; or (iii) during any period of two consecutive years, individuals who
at the beginning of such period constituted the Board of Directors (including
for this purpose any new director whose election or nomination for election by
the Corporation's stockholders was approved by a vote of at least two-thirds of
the directors then still in office who were directors at the beginning of such
period) cease for any reason to constitute at least a majority of the Board of
Directors.

         (ii) "Disinterested Director" means a director of the Corporation who
is not or was not a party to the Proceeding in respect of which indemnification
is sought by the Indemnitee.

         (iii) "Independent Counsel" means a law firm or a member of a law firm
that neither presently is, nor in the past five years has been, retained to
represent: (A) the Corporation or the Indemnitee in any matter material to
either such party, or (B) any other party to the Proceeding giving rise to a
claim for indemnification under this Article VIII. Notwithstanding the
foregoing, the term "Independent Counsel" shall not include any person who,
under the applicable standards

                                                                     Exhibit 3-B
                                                                   Page 15 of 15


of professional conduct then prevailing under the law of the State of Delaware,
would have a conflict of interest in representing either the Corporation or the
Indemnitee in an action to determine the Indemnitee's rights under this Article
VIII.

         (e) Severability. If any provision or provisions of this Article VIII
shall be held to be invalid, illegal or unenforceable for any reason whatsoever:
(i) the validity, legality, and enforceability of the remaining provisions of
this Article VIII (including, without limitation, all portions of any paragraph
of this Article VIII containing any such provision held to be invalid, illegal,
or unenforceable, that are not themselves invalid, illegal, or unenforceable)
shall not in any way be affected or impaired thereby; and (ii) to the fullest
extent possible, the provisions of this Article VIII (including, without
limitation, all portions of any paragraph of this Article VIII containing any
such provision held to be invalid, illegal, or unenforceable that are not
themselves invalid, illegal, or unenforceable) shall be construed so as to give
effect to the intent manifested by the provision held invalid, illegal, or
unenforceable.

         (f) Successor Laws, Regulations, and Agencies. Reference herein to
laws, regulations, or agencies shall be deemed to include all amendments
thereof, substitutions therefor, and successors thereto.

                                   ARTICLE IX

                                   AMENDMENTS
         Section 1. These Bylaws may be altered, amended, or repealed or new
Bylaws may be adopted by the stockholders or by the Board of Directors, when
such power is conferred upon the Board of Directors by the Certificate of
Incorporation, at any regular meeting of the stockholders or of the Board of
Directors or at any special meeting of the stockholders or of the Board of
Directors if notice of such alteration, amendment, repeal, or adoption of new
Bylaws be contained in the notice of such special meeting.

         Section 2. Before payment of any dividend, there may be set aside out
of any funds of the Corporation available for dividends such sum or sums as the
directors from time to time, in their absolute discretion, think proper as a
reserve or reserves to meet contingencies, or for equalizing dividends, or for
repairing or maintaining any property of the Corporation, or for such other
purpose as the directors shall think conducive to the interest of the
Corporation, and the directors may modify or abolish any such reserve in the
manner in which it was created.

Department, who need not be officers or employees of the Corporation to give in
the name of the Corporation telephonic, telegraphic, or electronic transfer
instructions for the payment of money, which may, with respect to routine items,
include instructions as to the amount to be transferred, to any bank, pursuant
to previously issued written orders, signed by officers of the Corporation or by
any employee of the Corporation so designated by the Board of Directors of the
Corporation in any manner provided above, which designate the recipients of such
amounts and which identify what shall be treated as routine items.

         Section 5. The corporate seal shall have inscribed thereon the name of

                                  ARTICLE VIII

                                 INDEMNIFICATION
         (a) Right to Indemnification. The Corporation shall to the fullest
extent permitted by applicable law as then in effect indemnify any person (the
"Indemnitee") who was or is involved in any manner (including, without
limitation, as a party or a witness) or is threatened to be made so involved in
any threatened, pending or completed investigation, claim, action, suit or
<PAGE>   140
                                                                     Exhibit 4-B
                                                                   Page 11 of 15


proceeding, whether civil, criminal, administrative, or investigative (including
without limitation, any action, suit, or proceeding by or in the right of the
Corporation to procure a judgment in its favor) (a "Proceeding") by reason of
the fact that such person is or was a director, officer, employee, or agent of
the Corporation, or is or was serving at the request of the Corporation as a
director, officer, employee, or agent of another Corporation, partnership, joint
venture, trust, or other enterprise (including, without limitation, any employee
benefit plan) against all expenses (including attorneys' fees), judgments,
fines, and amounts paid in settlement actually and reasonably incurred by such
person in connection with such Proceeding. Such indemnification shall be a
contract right and shall include the right to receive payment of any expenses
incurred by the Indemnitee in connection with such Proceeding in advance of its
final disposition, consistent with the provisions of applicable law as then in
effect.

         (b) Insurance, Contracts, and Funding. The Corporation may purchase and
maintain insurance to protect itself and any indemnitee against any expenses,
judgments, fines, and amounts paid in settlement as specified in Section (a) of
this Article VIII or incurred by an Indemnitee in connection with any proceeding
referred to in Section (a) of this Article VIII, to the fullest extent permitted
by applicable law as then in effect. The Corporation may enter into contracts
with any director, officer, employee, or agent of the Corporation or use other
means in furtherance of the provisions of this Article VIII to ensure the
payment of such amounts as may be necessary to effect indemnification as
provided in this Article VIII.

         (c) Indemnification; Not Exclusive Right. The right of indemnification
provided in this Article VIII shall not be exclusive of any other rights to
which those seeking indemnification may otherwise be entitled, and the
provisions of this Article VIII shall inure to the benefit of the heirs and
legal representatives of any person entitled to indemnity under this Article
VIII and shall be applicable to Proceedings commenced or continuing after the
adoption of this Article VIII, whether arising from acts or omissions occurring
before or after such adoption.

         (d) Advancement of Expenses; Procedures; Presumptions and Effect of
Certain Proceedings; Remedies. In furtherance but not in limitation of the
foregoing provisions, the following procedures, presumptions, and remedies shall
apply with respect to advancement of expenses and the right to indemnification
under this Article VIII:

         (1) Advance of Expenses. All reasonable expenses incurred by or on
behalf of the Indemnitee in connection with any Proceeding shall be advanced to
the Indemnitee by the Corporation within 20 days after the receipt by the
Corporation of a statement or statements from the Indemnitee requesting such
advance or advances from time to time, whether prior to or after final
disposition of such Proceeding. Such statement or statements shall reasonably
evidence the expenses incurred by the Indemnitee and, if required by law at the
time of such advance, shall include or be accompanied by an undertaking by or on
behalf of the Indemnitee to repay the amounts advanced if it should ultimately
be determined that the Indemnitee is not entitled to be indemnified against such
expenses pursuant to this Article VIII.

                                                                   Page 12 of 15


         (2) Procedure for Determination of Entitlement to Indemnification.
         (i) To obtain indemnification under this Article VIII, an Indemnitee
shall submit to the Secretary of the Corporation a written request, including
such documentation and information as is reasonably available to the Indemnitee
and reasonably necessary to determine whether and to what extent the Indemnitee
is entitled to indemnification (the "Supporting Documentation"). The
determination of the Indemnitee's entitlement to indemnification shall be made
not later than 60 days after receipt by the Corporation of the written request
for indemnification together with Supporting Documentation. The Secretary of the
Corporation shall advise the Board of Directors in writing, promptly upon
receipt of such a request for indemnification, that the Indemnitee has requested
indemnification.

         (ii) The Indemnitee's entitlement to indemnification under this Article
VIII shall be determined in one of the following ways: (A) by a majority vote of
the Disinterested Directors (as hereinafter defined), even if they constitute
less than a quorum of the Board of Directors; (B) by a written opinion of
Independent Counsel (as hereinafter defined) if (x) a Change of Control (as
hereinafter defined) shall have occurred and the Indemnitee so requests or (y) a
quorum of the Board of Directors consisting of Disinterested Directors is not
obtainable or, even if obtainable, a majority of such Disinterested Directors so
directs; (C) by the stockholders of the Corporation (but only if a majority of
the Disinterested Directors present the issue of entitlement to indemnification
to the stockholders for their determination); or (D) as provided in Section
(d)(3).

         (iii) In the event the determination of entitlement to indemnification
is to be made by Independent Counsel pursuant to Section (d)(2)(ii), a majority
of the Board of Directors shall select the Independent Counsel, but only an
Independent Counsel to which the Indemnitee does not reasonably object;
provided, however, that if a Change of Control shall have occurred, the
Indemnitee shall select such Independent Counsel, but only an Independent
Counsel to which the Board of Directors does not reasonably object.

         (iv) The only basis upon which a finding of no entitlement to
indemnification may be made is that indemnification is prohibited by law.

         (3) Presumptions and Effect of Certain Proceedings. Except as otherwise
expressly provided in this Article VIII, if a Change of Control shall have
occurred, the Indemnitee shall be presumed to be entitled to indemnification
under this Article VIII upon submission of a request for indemnification
together with the Supporting Documentation in accordance with Section (d)(2)(i),
and thereafter the Corporation shall have the burden of proof to overcome that
presumption in reaching a contrary determination. In any event, if the person or
persons empowered under Section (d)(2) to determine entitlement to
indemnification shall not have been appointed or shall not have made a
determination within 60 days after receipt by the Corporation of the request
therefor together with the Supporting Documentation, the Indemnitee shall be
deemed to be entitled to indemnification, and the Indemnitee shall be entitled
to such indemnification unless (A) the Indemnitee misrepresented or failed to
disclose a material fact in making the request for indemnification or in the
Supporting Documentation or (B) such
<PAGE>   142
                                                                     Exhibit 4-B
                                                                   Page 13 of 15


indemnification is prohibited by law. The termination of any Proceeding
described in Section (a), or of any claim, issue, or matter therein, by
judgment, order, settlement, or conviction, or upon a plea of nolo contendere or
its equivalent, shall not of itself adversely affect the right of the Indemnitee
to indemnification or create a presumption that the Indemnitee did not act in
good faith and in a manner which the Indemnitee reasonably believed to be in or
not opposed to the best interests of the Corporation or, with respect to any
criminal Proceeding, that the Indemnitee had reasonable cause to believe that
the Indemnitee's conduct was unlawful.

         (4)      Remedies of Indemnitee.
         (i) In the event that a determination is made pursuant to Section
(d)(2) or (3) that the Indemnitee is not entitled to indemnification under this
Article VIII, (A) the Indemnitee shall be entitled to seek an adjudication of
his entitlement to such indemnification either, at the Indemnitee's sole option,
in (x) an appropriate court of the State of Delaware or any other court of
competent jurisdiction, or (y) an arbitration to be conducted by a single
arbitrator pursuant to the rules of the American Arbitration Association; (B)
any such judicial proceeding or arbitration shall be de novo and the Indemnitee
shall not be prejudiced by reason of such adverse determination; and (C) in any
such judicial proceeding or arbitration, the Corporation shall have the burden
of proving that the Indemnitee is not entitled to indemnification under this
Article VIII.

         (ii) If pursuant to Section (d)(2) or (3) a determination shall have
been made or deemed to have been made that the Indemnitee is entitled to
indemnification, the Corporation shall be obligated to pay the amounts
constituting such indemnification within five days after such determination has
been made or is deemed to have been made and shall be conclusively bound by such
determination unless (A) the Indemnitee misrepresented or failed to disclose a
material fact in making the request for indemnification or in the Supporting
Documentation, or (B) such indemnification is prohibited by law. In the event
that (X) advancement of expenses is not timely made pursuant to Section (d)(l),
or (Y) payment of indemnification is not made within five days after a
determination of entitlement to indemnification has been made or deemed to have
been made pursuant to Section (d)(2) or (3), the Indemnitee shall be entitled to
seek judicial enforcement of the Corporation's obligation to pay to the
Indemnitee such advancement of expenses or indemnification. Notwithstanding the
foregoing, the Corporation may bring an action in an appropriate court in the
State of Delaware or any other court of competent jurisdiction, contesting the
right of the Indemnitee to receive indemnification hereunder due to the
occurrence of an event described in subclause (A) or (B) of this clause (ii) (a
"Disqualifying Event"); provided, however, that in any such action the
Corporation shall have the burden of proving the occurrence of such
Disqualifying Event.

         (iii) The Corporation shall be precluded from asserting in any judicial
proceeding or arbitration commenced pursuant to this Section (d)(4) that the
procedures and presumptions of this Article VIII are not valid, binding, and
enforceable and shall stipulate in any such court or before any such arbitrator
that the Corporation is bound by all the provisions of this Article VIII.

                                                                     Exhibit 4-B
                                                                   Page 14 of 15


         (iv) In the event that pursuant to this Section (d)(4) the Indemnitee
seeks a judicial adjudication of or an award in arbitration to enforce his
rights under, or to recover damages for breach of this Article VIII, the
Indemnitee shall be entitled to recover from the Corporation, and shall be
indemnified by the Corporation against, any expenses actually and reasonably
incurred by the Indemnitee if the Indemnitee prevails in such judicial
adjudication or arbitration. If it shall be determined in such judicial
adjudication or arbitration that the Indemnitee is entitled to receive part but
not all of the indemnification or advancement of expenses sought, the expenses
incurred by the Indemnitee in connection with such judicial adjudication or
arbitration shall be prorated accordingly.

         (5) Definitions. For purposes of this Section (d):
         (i) "Change in Control" means (A) so long as the Public Utility Holding
Company Act of 1935 is in effect, any "company" becoming a "holding company" in
respect to the Corporation or any determination by the Securities and Exchange
Commission that any "person" should be subject to the obligations, duties, and
liabilities if imposed by said Act by virtue or his, hers or its influence over
the management or policies of the Corporation, or (B) whether or not said Act is
in effect, a change in control of the Corporation of a nature that would be
required to be reported in response to Item 6(e) of Schedule 14A of Regulation
14A promulgated under the Securities Exchange Act of 1934 (the "Act"), whether
or not the Corporation is then subject to such reporting requirement; provided
that, without limitation, such a change in control shall be deemed to have
occurred if (i) any "person" (as such term is used in Section 13(d) and 14(d) of
the Act) is or becomes the "beneficial owner" (as defined in Rule 13d-3 under
the Act), directly or indirectly, of securities of the Corporation representing
10 percent or more of the combined voting power of the Corporation's then
outstanding securities without the prior approval of at least two-thirds of the
members of the Board of Directors in office immediately prior to such
acquisition; (ii) the Corporation is a party to a merger, consolidation, sale of
assets or other reorganization, or a proxy contest, as a consequence of which
members of the Board of Directors in office immediately prior to such
transaction or event constitute less than a majority of the Board of Directors
thereafter; or (iii) during any period of two consecutive years, individuals who
at the beginning of such period constituted the Board of Directors (including
for this purpose any new director whose election or nomination for election by
the Corporation's stockholders was approved by a vote of at least two-thirds of
the directors then still in office who were directors at the beginning of such
period) cease for any reason to constitute at least a majority of the Board of
Directors.

         (ii) "Disinterested Director" means a director of the Corporation who
is not or was not a party to the Proceeding in respect of which indemnification
is sought by the Indemnitee.

         (iii) "Independent Counsel" means a law firm or a member of a law firm
that neither presently is, nor in the past five years has been, retained to
represent: (A) the Corporation or the Indemnitee in any matter material to
either such party, or (B) any other party to the Proceeding giving rise to a
claim for indemnification under this Article VIII. Notwithstanding the
foregoing,
<PAGE>   144
                                                                     Exhibit 4-B

the term "Independent Counsel" shall not include any person who, under the
applicable standards of professional conduct then prevailing under the law of
the State of Delaware, would have a conflict of interest in representing either
the Corporation or the Indemnitee in an action to determine the Indemnitee's
rights under this Article VIII.

         (e) Severability. If any provision or provisions of this Article VIII
shall be held to be invalid, illegal or unenforceable for any reason whatsoever:
(i) the validity, legality, and enforceability of the remaining provisions of
this Article VIII (including, without limitation, all portions of any paragraph
of this Article VIII containing any such provision held to be invalid, illegal,
or unenforceable, that are not themselves invalid, illegal, or unenforceable)
shall not in any way be affected or impaired thereby; and (ii) to the fullest
extent possible, the provisions of this Article VIII (including, without
limitation, all portions of any paragraph of this Article VIII containing any
such provision held to be invalid, illegal, or unenforceable that are not
themselves invalid, illegal, or unenforceable) shall be construed so as to give
effect to the intent manifested by the provision held invalid, illegal, or
unenforceable.

         (f) Successor Laws, Regulations, and Agencies. Reference herein to
laws, regulations, or agencies shall be deemed to include all amendments
thereof, substitutions therefor, and successors thereto.

Bylaws may be adopted by the stockholders or by the Board of Directors, when

Directors or at any special meeting of the stockholders or of the Board of
Directors if notice of such alteration, amendment, repeal, or adoption of new

extent permitted by applicable law as then in effect indemnify any person (the

proceeding, whether civil, criminal, administrative, or investigative (including
without limitation, any action, suit, or proceeding by or in the right of the
Corporation to procure a judgment in its favor) (a "Proceeding") by reason of
the fact that such person is or was a director, officer, employee, or agent of
the Corporation, or is or was serving at the request of the Corporation as a
director, officer, employee, or agent of another Corporation, partnership, joint
venture, trust, or other enterprise (including, without limitation, any employee
benefit plan) against all expenses (including attorneys' fees), judgments,
fines, and amounts paid in settlement actually and reasonably incurred by such
person in connection with such Proceeding. Such indemnification shall be a
contract right and shall include the right to receive payment of any expenses
incurred by the Indemnitee in connection with such Proceeding in advance of its
final disposition, consistent with the provisions of applicable law as then in
effect.

         (b) Insurance, Contracts, and Funding. The Corporation may purchase and
maintain insurance to protect itself and any indemnitee against any expenses,
judgments, fines, and amounts paid in settlement as specified in Section (a) of
this Article VIII or incurred by an Indemnitee in connection with any proceeding
referred to in Section (a) of this Article VIII, to the fullest extent permitted
by applicable law as then in effect. The Corporation may enter into contracts
with any director, officer, employee, or agent of the Corporation or use other
means in furtherance of the provisions of this Article VIII to ensure the
payment of such amounts as may be necessary to effect indemnification as
provided in this Article VIII.

foregoing provisions, the following procedures, presumptions, and remedies shall
apply with respect to advancement of expenses and the right to indemnification
under this Article VIII:

the Indemnitee by the Corporation within 20 days after the receipt by the
Corporation of a statement or statements from the Indemnitee requesting such
advance or advances from time to time, whether prior to or after final
disposition of such Proceeding. Such statement or statements shall reasonably
evidence the expenses incurred by the Indemnitee and, if required by law at the
time of such advance, shall include or be accompanied by an undertaking by or on
behalf of the Indemnitee to repay the amounts advanced if it should ultimately
be determined that the Indemnitee is not entitled to be indemnified against such

                                                                   Page 12 of 15


         (2) Procedure for Determination of Entitlement to Indemnification.
         (i) To obtain indemnification under this Article VIII, an Indemnitee
shall submit to the Secretary of the Corporation a written request, including
such documentation and information as is reasonably available to the Indemnitee
and reasonably necessary to determine whether and to what extent the Indemnitee
is entitled to indemnification (the "Supporting Documentation"). The
determination of the Indemnitee's entitlement to indemnification shall be made
not later than 60 days after receipt by the Corporation of the written request
for indemnification together with Supporting Documentation. The Secretary of the
Corporation shall advise the Board of Directors in writing, promptly upon
receipt of such a request for indemnification, that the Indemnitee has requested
indemnification.

         (ii) The Indemnitee's entitlement to indemnification under this Article
VIII shall be determined in one of the following ways: (A) by a majority vote of
the Disinterested Directors (as hereinafter defined), even if they constitute
less than a quorum of the Board of Directors; (B) by a written opinion of
Independent Counsel (as hereinafter defined) if (x) a Change of Control (as
hereinafter defined) shall have occurred and the Indemnitee so requests or (y) a
quorum of the Board of Directors consisting of Disinterested Directors is not
obtainable or, even if obtainable, a majority of such Disinterested Directors so
directs; (C) by the stockholders of the Corporation (but only if a majority of
the Disinterested Directors present the issue of entitlement to indemnification
to the stockholders for their determination); or (D) as provided in Section
(d)(3).

         (iii) In the event the determination of entitlement to indemnification
is to be made by Independent Counsel pursuant to Section (d)(2)(ii), a majority
of the Board of Directors shall select the Independent Counsel, but only an
Independent Counsel to which the Indemnitee does not reasonably object;
provided, however, that if a Change of Control shall have occurred, the
Indemnitee shall select such Independent Counsel, but only an Independent
Counsel to which the Board of Directors does not reasonably object.

         (iv) The only basis upon which a finding of no entitlement to
indemnification may be made is that indemnification is prohibited by law.

         (3) Presumptions and Effect of Certain Proceedings. Except as otherwise
expressly provided in this Article VIII, if a Change of Control shall have
occurred, the Indemnitee shall be presumed to be entitled to indemnification
under this Article VIII upon submission of a request for indemnification
together with the Supporting Documentation in accordance with Section (d)(2)(i),
and thereafter the Corporation shall have the burden of proof to overcome that
presumption in reaching a contrary determination. In any event, if the person or
persons empowered under Section (d)(2) to determine entitlement to
indemnification shall not have been appointed or shall not have made a
determination within 60 days after receipt by the Corporation of the request
therefor together with the Supporting Documentation, the Indemnitee shall be
deemed to be entitled to indemnification, and the Indemnitee shall be entitled
to such indemnification unless (A) the Indemnitee misrepresented or failed to
disclose a material fact in making the request for indemnification or in the
Supporting Documentation or (B) such
<PAGE>   157
                                                                     Exhibit 5-B
                                                                   Page 13 of 15


indemnification is prohibited by law. The termination of any Proceeding
described in Section (a), or of any claim, issue, or matter therein, by
judgment, order, settlement, or conviction, or upon a plea of nolo contendere or
its equivalent, shall not of itself adversely affect the right of the Indemnitee
to indemnification or create a presumption that the Indemnitee did not act in
good faith and in a manner which the Indemnitee reasonably believed to be in or
not opposed to the best interests of the Corporation or, with respect to any
criminal Proceeding, that the Indemnitee had reasonable cause to believe that
the Indemnitee's conduct was unlawful.

         (4)      Remedies of Indemnitee.
         (i) In the event that a determination is made pursuant to Section
(d)(2) or (3) that the Indemnitee is not entitled to indemnification under this
Article VIII, (A) the Indemnitee shall be entitled to seek an adjudication of
his entitlement to such indemnification either, at the Indemnitee's sole option,
in (x) an appropriate court of the State of Delaware or any other court of
competent jurisdiction, or (y) an arbitration to be conducted by a single
arbitrator pursuant to the rules of the American Arbitration Association; (B)
any such judicial proceeding or arbitration shall be de novo and the Indemnitee
shall not be prejudiced by reason of such adverse determination; and (C) in any
such judicial proceeding or arbitration, the Corporation shall have the burden
of proving that the Indemnitee is not entitled to indemnification under this
Article VIII.

         (ii) If pursuant to Section (d)(2) or (3) a determination shall have
been made or deemed to have been made that the Indemnitee is entitled to
indemnification, the Corporation shall be obligated to pay the amounts
constituting such indemnification within five days after such determination has
been made or is deemed to have been made and shall be conclusively bound by such
determination unless (A) the Indemnitee misrepresented or failed to disclose a
material fact in making the request for indemnification or in the Supporting
Documentation, or (B) such indemnification is prohibited by law. In the event
that (X) advancement of expenses is not timely made pursuant to Section (d)(l),
or (Y) payment of indemnification is not made within five days after a
determination of entitlement to indemnification has been made or deemed to have
been made pursuant to Section (d)(2) or (3), the Indemnitee shall be entitled to
seek judicial enforcement of the Corporation's obligation to pay to the
Indemnitee such advancement of expenses or indemnification. Notwithstanding the
foregoing, the Corporation may bring an action in an appropriate court in the
State of Delaware or any other court of competent jurisdiction, contesting the
right of the Indemnitee to receive indemnification hereunder due to the
occurrence of an event described in subclause (A) or (B) of this clause (ii) (a
"Disqualifying Event"); provided, however, that in any such action the
Corporation shall have the burden of proving the occurrence of such
Disqualifying Event.

         (iii) The Corporation shall be precluded from asserting in any judicial
proceeding or arbitration commenced pursuant to this Section (d)(4) that the
procedures and presumptions of this Article VIII are not valid, binding, and
enforceable and shall stipulate in any such court or before any such arbitrator
that the Corporation is bound by all the provisions of this Article VIII.

                                                                   Page 14 of 15


         (iv) In the event that pursuant to this Section (d)(4) the Indemnitee
seeks a judicial adjudication of or an award in arbitration to enforce his
rights under, or to recover damages for breach of this Article VIII, the
Indemnitee shall be entitled to recover from the Corporation, and shall be
indemnified by the Corporation against, any expenses actually and reasonably
incurred by the Indemnitee if the Indemnitee prevails in such judicial
adjudication or arbitration. If it shall be determined in such judicial
adjudication or arbitration that the Indemnitee is entitled to receive part but
not all of the indemnification or advancement of expenses sought, the expenses
incurred by the Indemnitee in connection with such judicial adjudication or
arbitration shall be prorated accordingly.

         (5) Definitions. For purposes of this Section (d):
         (i) "Change in Control" means (A) so long as the Public Utility Holding
Company Act of 1935 is in effect, any "company" becoming a "holding company" in
respect to the Corporation or any determination by the Securities and Exchange
Commission that any "person" should be subject to the obligations, duties, and
liabilities if imposed by said Act by virtue or his, hers or its influence over
the management or policies of the Corporation, or (B) whether or not said Act is
in effect, a change in control of the Corporation of a nature that would be
required to be reported in response to Item 6(e) of Schedule 14A of Regulation
14A promulgated under the Securities Exchange Act of 1934 (the "Act"), whether
or not the Corporation is then subject to such reporting requirement; provided
that, without limitation, such a change in control shall be deemed to have
occurred if (i) any "person" (as such term is used in Section 13(d) and 14(d) of
the Act) is or becomes the "beneficial owner" (as defined in Rule 13d-3 under
the Act), directly or indirectly, of securities of the Corporation representing
10 percent or more of the combined voting power of the Corporation's then
outstanding securities without the prior approval of at least two-thirds of the
members of the Board of Directors in office immediately prior to such
acquisition; (ii) the Corporation is a party to a merger, consolidation, sale of
assets or other reorganization, or a proxy contest, as a consequence of which
members of the Board of Directors in office immediately prior to such
transaction or event constitute less than a majority of the Board of Directors
thereafter; or (iii) during any period of two consecutive years, individuals who
at the beginning of such period constituted the Board of Directors (including
for this purpose any new director whose election or nomination for election by
the Corporation's stockholders was approved by a vote of at least two-thirds of
the directors then still in office who were directors at the beginning of such
period) cease for any reason to constitute at least a majority of the Board of
Directors.

         (ii) "Disinterested Director" means a director of the Corporation who
is not or was not a party to the Proceeding in respect of which indemnification
is sought by the Indemnitee.

         (iii) "Independent Counsel" means a law firm or a member of a law firm
that neither presently is, nor in the past five years has been, retained to
represent: (A) the Corporation or the Indemnitee in any matter material to
either such party, or (B) any other party to the Proceeding giving rise to a
claim for indemnification under this Article VIII. Notwithstanding the
foregoing, the term "Independent Counsel" shall not include any person who,
under the applicable standards

                                                                     Exhibit 5-B
                                                                   Page 15 of 15


of professional conduct then prevailing under the law of the State of Delaware,
would have a conflict of interest in representing either the Corporation or the
Indemnitee in an action to determine the Indemnitee's rights under this Article
VIII.

         (e) Severability. If any provision or provisions of this Article VIII
shall be held to be invalid, illegal or unenforceable for any reason whatsoever:
(i) the validity, legality, and enforceability of the remaining provisions of
this Article VIII (including, without limitation, all portions of any paragraph
of this Article VIII containing any such provision held to be invalid, illegal,
or unenforceable, that are not themselves invalid, illegal, or unenforceable)
shall not in any way be affected or impaired thereby; and (ii) to the fullest
extent possible, the provisions of this Article VIII (including, without
limitation, all portions of any paragraph of this Article VIII containing any
such provision held to be invalid, illegal, or unenforceable that are not
themselves invalid, illegal, or unenforceable) shall be construed so as to give
effect to the intent manifested by the provision held invalid, illegal, or
unenforceable.

         (f) Successor Laws, Regulations, and Agencies. Reference herein to
laws, regulations, or agencies shall be deemed to include all amendments
thereof, substitutions therefor, and successors thereto.

                                   ARTICLE IX

                                   AMENDMENTS

         Section 1. These Bylaws may be altered, amended, or repealed or new
Bylaws may be adopted by the stockholders or by the Board of Directors, when
such power is conferred upon the Board of Directors by the Certificate of
Incorporation, at any regular meeting of the stockholders or of the Board of
Directors or at any special meeting of the stockholders or of the Board of
Directors if notice of such alteration, amendment, repeal, or adoption of new
Bylaws be contained in the notice of such special meeting.

         I.1 DEFINITIONS.

clearly indicated to the contrary, applied to the terms used in this Agreement.

         "Additional Limited Partner" means a Person admitted to the Partnership
as a Limited Partner pursuant to Section 10.4 and who is shown as such on the
books and records of the Partnership.

         "Adjusted Capital Account" means the Capital Account maintained for
each Partner as of the end of each fiscal year of the Partnership, (a) increased
by any amounts that such Partner is obligated to restore under the standards set
by Treasury Regulation Section 1.704-1(b)(2)(ii)(c) (or is deemed obligated to
restore under Treasury Regulation Sections 1.704-2(g) and 1.704-2(i)(5)) and (b)
decreased by (i) the amount of all losses and deductions that, as of the end of
such fiscal year, are reasonably expected to be allocated to such Partner in
subsequent years under Sections 704(e)(2) and 706(d) of the Code and Treasury
Regulation Section 1.751-1(b)(2)(ii), and (ii) the amount of all distributions
that, as of the end of such fiscal year, are reasonably expected to be made to
such Partner in subsequent years in accordance with the terms of this Agreement
or otherwise to the extent they exceed offsetting increases to such Partner's

year in which such distributions are reasonably expected to be made (other than
increases as a result of a minimum gain chargeback pursuant to Section 6.1(d)(i)
or 6.1(d)(ii)). The foregoing definition of Adjusted Capital Account is intended
to comply with the provisions of Treasury Regulation Section

"Adjusted Capital Account" of a Partner in respect of a general partner interest
or any other specified interest in the Partnership shall be the amount which

                                                                    Page 6 of 58

         "Agreed Value" of any Contributed Property means the fair market value
of such property or other consideration at the time of contribution as
determined by the Managing General Partner using such reasonable method of
valuation as it may adopt, but subject to the Purchase Agreement. The Managing

Agreement, use such method as it deems reasonable and appropriate to allocate
the aggregate Agreed Value of Contributed Properties contributed to the
Partnership in a single or integrated transaction among each separate property
on a basis proportional to the fair market value of each Contributed Property.

Partnership of National Propane, L.P., as it may be amended, supplemented or
restated from time to time.

determination of Available Cash with respect to such Quarter resulting from
borrowings for working capital purposes, in each case subsequent to the end of

agreement, security agreement, mortgage, debt instrument or other agreement or
obligation to which any member of the Partnership Group is a party or by which
it is bound or its assets are subject; provided, however, that disbursements
made by a Group Member or cash reserves established, increased or reduced after
the end of such Quarter but on or before the date of determination of Available
Cash with respect to such Quarter shall be deemed to have been made,
established, increased or reduced, for purposes of determining Available Cash,

Property or Adjusted Property, as of the date of any determination, the
difference between the Carrying Value of such Contributed Property or Adjusted
Property and the adjusted basis thereof for federal income tax purposes as of
such date. A Partner's share of the Partnership's Book-Tax Disparities in all of
its Contributed Property and Adjusted Property will be reflected by the
difference between such Partner's Capital Account balance as maintained pursuant
to Section 5.5 and the hypothetical balance of such Partner's Capital Account
computed as if it had been maintained strictly in accordance with federal income
tax accounting principles.

with respect to any other Partnership property, the adjusted basis of such
property for federal income tax purposes, in each case, as of the time of
determination and adjusted in accordance with Sections 5.5(d)(i) and 5.5(d)(ii)
and to reflect changes, additions or other adjustments to the Carrying Value, as
deemed appropriate by the Managing General Partner.

         "Certificate of Limited Partnership" means the Certificate of Limited
Partnership of the Partnership filed with the Secretary of State of the State of

Capital Contributions reduced by any distributions to such Partner of any
portion of such Partner's Capital Contributions. For purposes of this

such form as may be permitted by the Delaware Act, but excluding cash,

                  (a) The term "transfer," when used in this Agreement with
respect to a Partner Interest, shall be deemed to refer to a transaction by
which a Partner assigns its Partner Interest to another Person, and includes a
sale, assignment, gift, pledge, encumbrance, hypothecation, mortgage, exchange
or any other disposition by law or otherwise.

                  (b) No Partner Interest shall be transferred, in whole or
in part, except in accordance with the terms and conditions set forth in this
Article IV. Any transfer or purported transfer of a Partner Interest not made in
accordance with this Article IV shall be null and void.

                  (c) Nothing contained in this Agreement shall be
construed to prevent a disposition by any shareholder of a General Partner of
any or all of the issued and outstanding capital stock of a General Partner.

         IV.2 TRANSFER OF GENERAL PARTNER PARTNER INTEREST.

         A General Partner may transfer all or any part of its Partner Interest
as the General Partner of the Partnership to any Person and the Limited Partners
hereby expressly consent to any such transfer.

         IV.3 TRANSFER OF LIMITED PARTNER PARTNER INTERESTS.

         Any Class A Limited Partner may transfer any or all of its Partner
Interest as a limited partner of the Partnership to any Person and following any
such transfer such Person may become a Substituted Limited Partner pursuant to
Article X. Without the prior written consent of the Managing General Partner,
the Special Limited Partner may not transfer any part of its Partner Interest,
other that as set forth in Section 4.5; provided that notwithstanding the
foregoing, the Special Limited Partner may transfer all, but not less than all,
of its Partner Interest to any affiliate of the Special Limited Partner, and for
this purpose only "affiliate" shall have the meaning assigned to such term in
Rule 12b-2 under the Securities Exchange Act of 1934, as amended.

                                                                   Page 20 of 58


         IV.4 RESTRICTIONS ON TRANSFERS.

                  (a) Notwithstanding any other provision of this Article
IV, no transfer of any Partner Interest shall be made if such transfer would (i)
violate the then applicable federal or state securities laws or rules and
regulations of the Commission, any state securities commission or any other
governmental authorities with jurisdiction over such transfer, (ii) terminate
the existence or qualification of the Partnership under the laws of the
jurisdiction of its formation or (iii) cause the Partnership to be treated as an
association taxable as a corporation or otherwise to be taxed as an entity for
federal income tax purposes (to the extent not already so treated or taxed).

                  (b) The Managing General Partner may impose restrictions
on the transfer of Partner Interests if a subsequent Opinion of Counsel
determines that such restrictions are necessary to avoid a significant risk of
the Partnership's or the MLP's becoming taxable as a corporation or otherwise to
be taxed as an entity for federal income tax purposes. The restrictions may be
imposed by making such amendments to this Agreement as the Managing General
Partner may determine to be necessary or appropriate to impose such
restrictions.

         IV.5 PUT AND CALL TRANSACTIONS INVOLVING SPECIAL LIMITED PARTNER
PARTNER INTERESTS.

                  (a) At any time, the Special Limited Partner may require,
upon 30 days prior written notice to the Managing General Partner and the
Partnership, that the Partnership purchase all (but not less than all) of the
Special Limited Partner's Partner Interest; provided that as a condition to the
obligation of the Partnership to purchase such Special Limited Partner's Partner
Interest, (i) the Special Limited Partner must deliver good and valid title to
the Special Limited Partner's Partner Interest, free and clear of all liens,
claims and other encumbrances and (ii) any waiting periods under the
Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended (the "HSR
Act"), or otherwise, shall have expired or been terminated. The Partnership may
elect to have an Affiliate make such purchase. The purchase price shall consist
of cash in an amount equal to the fair market value of the Special Limited
Partner's Partner Interest as of the date of the notice, determined by a
nationally recognized independent appraiser or investment banking firm selected
by the Managing General Partner. Any payment pursuant to this paragraph shall be
made by wire transfer of immediately available funds no later than 30 days after
the date of such notice. The Partnership shall not be obligated to purchase the
Special Limited Partner's Partner Interest unless the Special Limited Partner
delivers good and valid title to the Special Limited Partner's Partner Interest,
free and clear of all liens, claims and other encumbrances.

                  (b) At any time, the Managing General Partner may
require, upon 30 days prior written notice to the Special Limited Partner, that
the Special Limited Partner sell to the Partnership all (but not less than all)
of the Special Limited Partner's Partner Interest in consideration of (i) the
payment of the cash price as provided in Section 4.5(a), and (ii) an additional
amount in cash, if such sale is consummated prior to July 19, 2009, equal to (A)
any incremental gain realized by the Special Limited Partner resulting from a
decrease in its share of Indemnified Debt, multiplied by (B) a fraction, the
numerator of which is the Effective Tax Rate and the denominator of which is one
minus the Effective Tax Rate. Such purchase shall be effected no later than 30
days after the date

                                                                     Exhibit 7-B
                                                                   Page 21 of 58


of the notice. Any payment pursuant to this paragraph shall be made by wire
transfer of immediately available funds no later than 30 days after the date of
such notice, subject to the prior expiration or termination of any applicable
waiting periods under the HSR Act or otherwise. The Special Limited Partner
shall deliver good and valid title to the Special Limited Partner Partner
Interest free and clear of all liens, claims and other encumbrances in the event
this call right is exercised.

                       CONTRIBUTIONS AND INITIAL TRANSFERS

         V.1 INITIAL CONTRIBUTIONS.

Capital Contribution to the Partnership in the aggregate amount of $20.96 in
exchange for a 2.0956% interest in the Partnership and each was admitted as a
general partner of the Partnership, (ii) National Propane Partners, L.P. made a
net Capital Contribution to the Partnership in the amount of $.01 in exchange
for a .0001% interest in the Partnership and was admitted as a limited partner

non-managing general partner interest.

         (b)  On July 2, 1996:

                  (i) The Special Limited Partner and National Propane SGP, Inc.
conveyed substantially all of their assets to the Partnership. In exchange, the
Partnership (A) increased the general partner interests of the Partnership so
that each of the Special Limited Partner and National Propane SGP, Inc. had a
2.2648% general partner interest in the Partnership, (B) decreased the limited
partner interests of the Partnership so that the Special Limited Partner and
National Propane SGP, Inc. had a combined 95.4703% limited partner interest in
the Partnership and (C) assumed certain liabilities.

                  (ii) The Special Limited Partner and National Propane SGP,
L.P., thereafter conveyed all their limited partner interest in the Partnership
to National Propane Partners, L.P., in exchange for the interests received
pursuant to Section 5.2 of the Amended and Restated Agreement of Limited
Partnership of National Propane Partners, L.P. dated as of July 2, 1996.

                  (iii) After the Partnership utilized approximately $62.2
million received pursuant to Section 5.1(b)(i) above to repay a portion of the
indebtedness assumed in Section 5.1(b)(ii) above, National Propane Partners,
L.P. contributed approximately $118.2 million to the Partnership. As a result of
these conveyances, National Propane Partners, L.P. received an additional
limited partner

                                                                   Page 22 of 58


interest in the Partnership so that its aggregate limited partner interest in
the Partnership was 97.9798% and the Special Limited Partner and National
Propane SGP, Inc. each had a 1.0101% general partner interest in the
Partnership.

         V.2 CONTRIBUTIONS PURSUANT TO THE PURCHASE AGREEMENT.

                  (a) On July 19, 1999, pursuant to the Purchase Agreement, the
Special Limited Partner caused (i) National Propane Partners, L.P. to redeem (A)
all 1.0% of the unsubordinated general partner interests in National Propane
Partners, L.P. owned by National Propane SGP, Inc. in exchange for the
simultaneous distribution to National Propane SGP, Inc. of a 0.9798% limited
partner interest in the Partnership, (B) all 4,533,638 outstanding units
representing subordinated general partner interests in National Propane
Partners, L.P. and all incentive distribution rights representing general
partner interests in National Propane Partners, L.P. owned by the Special
Limited Partner in exchange for the simultaneous distribution to the Special
Limited Partner of a 22.6351% limited partner interest in the Partnership and
(C) all 1.0% of the unsubordinated general partner interests in National Propane
Partners, L.P. owned by the Special Limited Partner (other than a general
partner interest valued at $1,000, which was subsequently purchased by the
Managing General Partner for $1,000) in exchange for the simultaneous
distribution to the Special Limited Partner of a 0.9798% limited partner
interest in the Partnership, and immediately thereafter, (ii) the Partnership to
redeem all of the units representing limited partner interests in the
Partnership owned by the Special Limited Partner other than a 1.0% limited
partner interest (inclusive of the interest in (C) above) in exchange for the
simultaneous assignment and distribution to the Special Limited Partner of the
promissory note in the original amount of $40,700,000, the principal amount of
which (at the time of the assignment and distribution referred to in this clause
(ii)) will be $15,816,280, issued by Triarc Companies, Inc. to the order of the
Partnership.

                  (b) Immediately thereafter, (i) the MLP purchased all of the
limited partner interests in the Partnership owned by National Propane SGP, Inc.
for an aggregate consideration of $686,000, and (ii) the Managing General
Partner purchased (A) all of the general partner interests in the Partnership
owned by National Propane SGP, Inc. for an aggregate consideration of $707,000,
and (B) all of the general partner interests in the Partnership owned by the
Special Limited Partner (other than a general partner interest valued at $1,000,
which was subsequently purchased by the Managing General Partner for $1,000) for
an aggregate consideration of $706,000. As contemplated by the Purchase
Agreement, pursuant to this Agreement, the 1.0% limited partner interest
referred to above has been converted into the Special Limited Partner Partner
Interest.

         V.3 ADDITIONAL CAPITAL CONTRIBUTIONS.

                  The Special Limited Partner may, but shall not be obligated
to, make additional Capital Contributions from time to time to the Partnership
in order to maintain its Percentage Interest at 1.0%. Except as provided in the
immediately preceding sentence, no Limited Partner shall be entitled to make
additional Capital Contributions to the Partnership without prior written
consent of the Managing General Partner. The Managing General Partner may make
additional Capital Contributions to the Partnership at any time.

                                                                   Page 23 of 58


         V.4 INTEREST AND WITHDRAWAL.

         No interest shall be paid by the Partnership on Capital Contributions,
and no Partner shall be entitled to withdrawal or return of any part of its
Capital Contributions or to receive any distribution from the Partnership,
except as provided in Articles VI, XI and XII.

         V.5 CAPITAL ACCOUNTS.

                  (a) The Partnership shall maintain for each Partner
owning a Partner Interest a separate Capital Account with respect to such
Partner Interest in accordance with the rules of Treasury Regulation Section
1.704-1(b)(2)(iv). Such Capital Account shall be increased by (i) the amount of
all Capital Contributions made to the Partnership with respect to such Partner
Interest pursuant to this Agreement and (ii) all items of Partnership income and
gain (including, without limitation, income and gain exempt from tax) computed
in accordance with Section 5.5(b) and allocated with respect to such Partner
Interest pursuant to Section 6.1, and decreased by (x) the amount of cash or the
Net Agreed Value of all actual and deemed distributions of cash or property made
with respect to such Partner Interest pursuant to this Agreement and (y) all
items of Partnership deduction and loss computed in accordance with Section
5.5(b) and allocated with respect to such Partner Interest pursuant to Section
6.1.

                  (b) For purposes of computing the amount of any item of
income, gain, loss or deduction which is to be allocated pursuant to Article VI
and is to be reflected in the Partners' Capital Accounts, the determination,
recognition and classification of any such item shall be the same as its
determination, recognition and classification for federal income tax purposes
(including, without limitation, any method of depreciation, cost recovery or
amortization used for that purpose), provided, that:

                           (i) Solely for purposes of this Section 5.5, the
         Partnership shall be treated as owning directly its proportionate share
         (as determined by the Managing General Partner) of all property owned
         by any OLP Subsidiary that is classified as a partnership for federal
         income tax purposes.

                           (ii) All fees and other expenses incurred by the
         Partnership to promote the sale of (or to sell) a Partner Interest that
         can neither be deducted nor amortized under Section 709 of the Code, if
         any, shall, for purposes of Capital Account maintenance, be treated as
         an item of deduction at the time such fees and other expenses are
         incurred and shall be allocated among the Partners pursuant to Section
         6.1.

                           (iii) Except as otherwise provided in Treasury
         Regulation Section 1.704- 1(b)(2)(iv)(m), the computation of all items
         of income, gain, loss and deduction shall be made without regard to any
         election under Section 754 of the Code which may be made by the
         Partnership and, as to those items described in Section 705(a)(1)(B) or
         705(a)(2)(B) of the Code, without regard to the fact that such items
         are not includable in gross income or are neither currently deductible
         nor capitalized for federal income tax purposes. To the extent
<PAGE>   186
                                                                     Exhibit 7-B
                                                                   Page 24 of 58


         an adjustment to the adjusted tax basis of any Partnership asset
         pursuant to Section 734(b) or 743(b) of the Code is required, pursuant
         to Treasury Regulation Section 1.704- 2(b)(2)(iv)(m) to be taken into
         account in determining Capital Accounts, the amount of such adjustment
         in the Capital Accounts shall be treated as an item of gain or loss.

                           (iv) Any income, gain or loss attributable to the
         taxable disposition of any Partnership property shall be determined as
         if the adjusted basis of such property as of such date of disposition
         were equal in amount to the Partnership's Carrying Value with respect
         to such property as of such date.

                           (v) In accordance with the requirements of Section
         704(b) of the Code, any deductions for depreciation, cost recovery or
         amortization attributable to any Contributed Property shall be
         determined as if the adjusted basis of such property on the date it was
         acquired by the Partnership were equal to the Agreed Value of such
         property. Upon an adjustment pursuant to Section 5.5(d) to the Carrying
         Value of any Partnership property subject to depreciation, cost
         recovery or amortization, any further deductions for such depreciation,
         cost recovery or amortization attributable to such property shall be
         determined (A) as if the adjusted basis of such property were equal to
         the Carrying Value of such property immediately following such
         adjustment and (B) using a rate of depreciation, cost recovery or
         amortization derived from the same method and useful life (or, if
         applicable, the remaining useful life) as is applied for federal income
         tax purposes; provided, however, that, if the asset has a zero adjusted
         basis for federal income tax purposes, depreciation, cost recovery or
         amortization deductions shall be determined using any reasonable method
         that the Managing General Partner may adopt.

                           (vi) If the Partnership's adjusted basis in a
         depreciable or cost recovery property is reduced for federal income tax
         purposes pursuant to Section 48(q)(1) or 48(q)(3) of the Code, the
         amount of such reduction shall, solely for purposes hereof, be deemed
         to be an additional depreciation or cost recovery deduction in the year
         such property is placed in service and shall be allocated among the
         Partners pursuant to Section 6.1. Any restoration of such basis
         pursuant to Section 48(q)(2) of the Code shall, to the extent possible,
         be allocated in the same manner to the Partners to whom such deemed
         deduction was allocated.

                  (c) A transferee of a Partner Interest shall succeed to a
pro rata portion of the Capital Account of the transferor relating to the
Partner Interest so transferred; provided, however, that, if the transfer causes
a termination of the Partnership under Section 708(b)(1)(B) of the Code, the
Partnership's properties, liabilities and the Capital Accounts shall be treated
as mandated by Treasury Regulations issued pursuant to Sections 708 and 704 of
the Code, as amended. The Capital Accounts of such new Partnership shall be
maintained in accordance with the principles of this Section 5.5.

                  (d) (i) In accordance with Treasury Regulation Section
1.704-1(b)(2)(iv)(f), on an issuance of additional Partner Interests for cash or
Contributed Property, the Capital Account of all Partners and the Carrying Value
of each Partnership property immediately prior to such issuance
<PAGE>   187
                                                                     Exhibit 7-B
                                                                   Page 25 of 58


shall be adjusted upward or downward to reflect any Unrealized Gain or
Unrealized Loss attributable to such Partnership property, as if such Unrealized
Gain or Unrealized Loss had been recognized on an actual sale of each such
property immediately prior to such issuance and had been allocated to the
Partners at such time pursuant to Section 6.1(c). In determining such Unrealized
Gain or Unrealized Loss, the aggregate cash amount and fair market value of all
Partnership assets (including, without limitation, cash or cash equivalents)
immediately prior to the issuance of additional Partner Interests shall be
determined by the Managing General Partner using such reasonable method of
valuation as it may adopt; provided, however, that the Managing General Partner,
in arriving at such valuation, must take fully into account the fair market
value of the Partner Interests of all Partners at such time. The Managing
General Partner shall allocate such aggregate value among the assets of the
Partnership (in such manner as it determines in its discretion to be reasonable)
to arrive at a fair market value for individual properties.

                           (ii) In accordance with Treasury Regulation Section
1.704-1(b)(2)(iv)(f), immediately prior to any actual or deemed distribution to
a Partner of any Partnership property (other than a distribution of cash that is
not in redemption or retirement of a Partner Interest), the Capital Accounts of
all Partners and the Carrying Value of all Partnership property shall be
adjusted upward or downward to reflect any Unrealized Gain or Unrealized Loss
attributable to such Partnership property, as if such Unrealized Gain or
Unrealized Loss had been recognized in a sale of such property immediately prior
to such distribution for an amount equal to its fair market value, and had been
allocated to the Partners, at such time, pursuant to Section 6.1(c). In
determining such Unrealized Gain or Unrealized Loss the aggregate cash amount
and fair market value of all Partnership assets (including, without limitation,
cash or cash equivalents) immediately prior to a distribution shall (A) in the
case of an actual distribution which is not made pursuant to Section 12.4, be
determined and allocated in the same manner as that provided in Section
5.5(d)(i) or (B) in the case of a liquidating distribution pursuant to Section
12.4, be determined and allocated by the Liquidator using such reasonable method
of valuation as it may adopt.

         V.6 LOANS FROM PARTNERS.

         Loans by a Partner to the Partnership shall not constitute Capital
Contributions. If any Partner shall advance funds to the Partnership in excess
of the amounts required hereunder to be contributed by it to the capital of the
Partnership, the making of such excess advances shall not result in any increase
in the amount of the Capital Account of such Partner. The amount of any such
excess advances shall be a debt obligation of the Partnership to such Partner
and shall be payable or collectible only out of the Partnership assets in
accordance with the terms and conditions upon which such advances are made.

         V.7 LIMITED PREEMPTIVE RIGHTS.

         Except as provided in Section 5.3, no Person shall have preemptive,
preferential or other similar rights with respect to (a) additional Capital
Contributions; (b) issuance or sale of any class or series of Partner Interests,
whether unissued, held in the treasury or hereafter created; (c) issuance of any
obligations, evidences of indebtedness or other securities of the Partnership
convertible into

                                                                     Exhibit 7-B

or exchangeable for, or carrying or accompanied by any rights to receive,
purchase or subscribe to, any such Partner Interests; (d) issuance of any right
of subscription to or right to receive, or any warrant or option for the
purchase of, any such Partner Interests; or (e) issuance or sale of any other
securities that may be issued or sold by the Partnership.

         V.8 FULLY PAID AND NON-ASSESSABLE NATURE OF LIMITED PARTNER PARTNER
INTERESTS.

         All Limited Partner Partner Interests issued pursuant to, and in
accordance with the requirements of, this Article V shall be fully paid and
non-assessable Partner Interests in the Partnership, except as such
non-assessability may be affected by Section 17-607 of the Delaware Act.

                                   ARTICLE VI

                          ALLOCATIONS AND DISTRIBUTIONS

         VI.1 ALLOCATIONS FOR CAPITAL ACCOUNT PURPOSES.

         For purposes of maintaining the Capital Accounts and in determining the
rights of the Partners among themselves, the Partnership's items of income,
gain, loss and deduction (computed in accordance with Section 5.5(b)) shall be
allocated among the Partners in each taxable year (or portion thereof) as
provided hereinbelow.

                  (a) Net Income. After giving effect to the special
allocations set forth in Section 6.1(d), Net Income for each taxable year (or
portion thereof) and all items of income, gain, loss and deduction taken into
account in computing Net Income for such taxable year (or portion thereof) shall
be allocated as follows:

                           (i) First, 100% to the General Partners, in
         accordance with their respective Percentage Interests, until the
         aggregate Net Income allocated to the General Partners pursuant to this
         Section 6.1(a)(i) for the current taxable year (or portion thereof) and
         all previous taxable years is equal to the aggregate Net Losses
         allocated to the General Partners pursuant to Section 6.1(b)(ii) for
         all previous taxable years;

                           (ii) Second, 100% to the General Partners and the
         Limited Partners, in accordance with their respective Percentage
         Interests.

                  (b) Net Losses. After giving effect to the special
allocations set forth in Section 6.1(d), Net Losses for each taxable year (or
portion thereof) and all items of income, gain, loss and deduction taken into
account in computing Net Losses for such taxable year (or portion thereof) shall
be allocated as follows:

                                                                     Exhibit 7-B
                                                                   Page 27 of 58


                           (i) First, 100% to the General Partners and the
         Limited Partners, in accordance with their respective Percentage
         Interests; provided, that Net Losses shall not be allocated pursuant to
         this Section 6.1(b)(i) to the extent that such allocation would cause a
         Limited Partner to have a deficit balance in its Adjusted Capital
         Account at the end of such taxable year (or increase any existing
         deficit balance in its Adjusted Capital Account) greater than the
         amount it is obligated to restore;

                           (ii) Second, the balance, if any, 100% to the General
         Partners, in accordance with their respective Percentage Interests.

                  (c) Net Termination Gains and Losses. After giving effect
to the special allocations set forth in Section 6.1(d), all items of income,
gain, loss and deduction taken into account in computing Net Termination Gain or
Net Termination Loss for such taxable period shall be allocated in the same
manner as such Net Termination Gain or Net Termination Loss is allocated
hereunder. All allocations under this Section 6.1(c) shall be made after Capital
Account balances have been adjusted by all other allocations provided under this
Section 6.1 and after all distributions provided under Section 6.3(a) have been
made with respect to the taxable period ending on or before the Liquidation
Date; provided, however, that solely for purposes of this Section 6.1(c),
Capital Accounts shall not be adjusted for distributions made pursuant to
Section 12.4.

                           (i) If a Net Termination Gain is recognized (or
         deemed recognized pursuant to Section 5.5(d)), such Net Termination
         Gain shall be allocated between the General Partners and the Limited
         Partners in the following manner (and the Capital Accounts of the
         Partners shall be increased by the amount so allocated in each of the
         following subclauses, in the order listed, before an allocation is made
         pursuant to the next succeeding subclause):

                                    (A) First, to each Partner having a deficit
         balance in its Capital Account, in the proportion that such deficit
         balance bears to the total deficit balances in the Capital Accounts of
         all Partners, until each such Partner has been allocated Net
         Termination Gain equal to any such deficit balance in its Capital
         Account; and

                                    (B) Second, 100% to the General Partners and
         the Limited Partners in accordance with their respective Percentage
         Interests.

                           (ii) If a Net Termination Loss is recognized (or
         deemed recognized pursuant to Section 5.5(d)), such Net Termination
         Loss shall be allocated to the Partners in the following manner (and
         the Capital Accounts of the Partners shall be decreased by the amount
         so allocated in each of the following subclauses, in the order listed,
         before an allocation is made pursuant to the next succeeding
         subclause):

                                    (A) First, 100% to the General Partners and
         the Limited Partners in proportion to, and to the extent of, the
         positive balances in their respective Capital Accounts; and
<PAGE>   190
                                                                     Exhibit 7-B
                                                                   Page 28 of 58


                                    (B) Second, the balance, if any, 100% to the
         General Partners, in accordance with their respective Percentage
         Interests.

                  (d) Special Allocations. Notwithstanding any other
provision of this Section 6.1, the following special allocations shall be made
for such taxable year (or portion thereof):

                           (i) Partnership Minimum Gain Chargeback.
         Notwithstanding any other provision of this Section 6.1, if there is a
         net decrease in Partnership Minimum Gain during any Partnership taxable
         period, each Partner shall be allocated items of Partnership income and
         gain for such period (and, if necessary, subsequent periods) in the
         manner and amounts provided in Treasury Regulation Sections
         1.704-2(f)(6), 1.704-2(g)(2) and 1.704-2(j)(2)(i), or any successor
         provision. For purposes of this Section 6.1(d), each Partner's Adjusted
         Capital Account balance shall be determined, and the allocation of
         income or gain required hereunder shall be effected, prior to the
         application of any other allocations pursuant to this Section 6.1(d)
         with respect to such taxable period (other than an allocation pursuant
         to Sections 6.1(d)(v) and 6.1(d)(vi)). This Section 6.1(d)(i) is
         intended to comply with the Partnership Minimum Gain chargeback
         requirement in Treasury Regulation Section 1.704- 2(f) and shall be
         interpreted consistently therewith.

                           (ii) Chargeback of Partner Nonrecourse Debt Minimum
         Gain. Notwithstanding the other provisions of this Section 6.1 (other
         than Section 6.1(d)(i)), except as provided in Treasury Regulation
         Section 1.704-2(i)(4), if there is a net decrease in Partner
         Nonrecourse Debt Minimum Gain during any Partnership taxable period,
         any Partner with a share of Partner Nonrecourse Debt Minimum Gain at
         the beginning of such taxable period shall be allocated items of
         Partnership income and gain for such period (and, if necessary,
         subsequent periods) in the manner and amounts provided in Treasury
         Regulation Sections 1.704-2(i)(4) and 1.704-2(j)(2)(ii), or any
         successor provisions. For purposes of this Section 6.1(d), each
         Partner's Adjusted Capital Account balance shall be determined, and the
         allocation of income or gain required hereunder shall be effected,
         prior to the application of any other allocations pursuant to this
         Section 6.1(d), other than Section 6.1(d)(i) and other than an
         allocation pursuant to Sections 6.1(d)(v) and 6.1(d)(vi), with respect
         to such taxable period. This Section 6.1(d)(ii) is intended to comply
         with the chargeback of items of income and gain requirement in Treasury
         Regulation Section 1.704-2(i)(4) and shall be interpreted consistently
         therewith.

                           (iii) Qualified Income Offset. In the event any
         Partner unexpectedly receives any adjustments, allocations or
         distributions described in Treasury Regulation Sections
         1.704-1(b)(2)(ii)(d)(4), 1.704-1(b)(2)(ii)(d)(5), or
         1.704-1(b)(2)(ii)(d)(6), items of Partnership income and gain shall be
         specially allocated to such Partner in an amount and manner sufficient
         to eliminate, to the extent required by the Treasury Regulations
         promulgated under Section 704(b) of the Code, the deficit balance, if
         any, in its Adjusted Capital Account created by such adjustments,
         allocations or distributions as quickly as possible unless such deficit
         balance is otherwise eliminated pursuant to Section 6.1(d)(i) or (ii).

                                                                     Exhibit 7-B
                                                                   Page 29 of 58


                           (iv) Gross Income Allocations. In the event any
         Partner has a deficit balance in its Capital Account at the end of any
         Partnership taxable period in excess of the sum of (A) the amount such
         Partner is required to restore pursuant to the provisions of this
         Agreement and (B) the amount such Partner is deemed obligated to
         restore pursuant to Treasury Regulation Sections 1.704-2(g) and
         1.704-2(i)(5), such Partner shall be specially allocated items of
         Partnership gross income and gain in the amount of such excess as
         quickly as possible; provided, that an allocation pursuant to this
         Section 6.1(d)(iv) shall be made only if and to the extent that such
         Partner would have a deficit balance in its Capital Account as adjusted
         after all other allocations provided in this Section 6.1 have been
         tentatively made as if this Section 6.1(d)(iv) were not in this
         Agreement.

                           (v) Nonrecourse Deductions. Nonrecourse Deductions
         for any taxable period shall be allocated to the Partners in accordance
         with their respective Percentage Interests. If the Managing General
         Partner determines in its good faith discretion that the Partnership's
         Nonrecourse Deductions must be allocated in a different ratio to
         satisfy the safe harbor requirements of the Treasury Regulations
         promulgated under Section 704(b) of the Code, the Managing General
         Partner is authorized, upon notice to the Limited Partners, to revise
         the prescribed ratio to the numerically closest ratio that does satisfy
         such requirements.

                           (vi) Partner Nonrecourse Deductions. Partner
         Nonrecourse Deductions for any taxable period shall be allocated 100%
         to the Partner that bears the Economic Risk of Loss with respect to the
         Partner Nonrecourse Debt to which such Partner Nonrecourse Deductions
         are attributable in accordance with Treasury Regulation Section
         1.704-2(i). If more than one Partner bears the Economic Risk of Loss
         with respect to a Partner Nonrecourse Debt, such Partner Nonrecourse
         Deductions attributable thereto shall be allocated between or among
         such Partners in accordance with the ratios in which they share such
         Economic Risk of Loss.

                           (vii) Nonrecourse Liabilities. For purposes of
         Treasury Regulation Section 1.752-3(a)(3), the Partners agree that
         Nonrecourse Liabilities of the Partnership in excess of the sum of (A)
         the amount of Partnership Minimum Gain and (B) the total amount of
         Nonrecourse Built-in Gain shall be allocated among the Partners in
         accordance with their respective Percentage Interests.

                           (viii) Code Section 754 Adjustments. To the extent an
         adjustment to the adjusted tax basis of any Partnership asset pursuant
         to Section 734(b) or 743(c) of the Code is required, pursuant to
         Treasury Regulation Section 1.704-1(b)(2)(iv)(m), to be taken into
         account in determining Capital Accounts, the amount of such adjustment
         to the Capital Accounts shall be treated as an item of gain (if the
         adjustment increases the basis of the asset) or loss (if the adjustment
         decreases such basis), and such item of gain or loss shall be specially
         allocated to the Partners in a manner consistent with the manner in
         which their Capital Accounts are required to be adjusted pursuant to
         such Section of the Treasury Regulations.

                                                                   Page 30 of 58


                           (ix)  Curative Allocation.

                                    (A) Notwithstanding any other provision of
         this Section 6.1, other than the Required Allocations, the Required
         Allocations shall be taken into account in making the Agreed
         Allocations so that, to the extent possible, the net amount of items of
         income, gain, loss and deduction allocated to each Partner pursuant to
         the Required Allocations and the Agreed Allocations, together, shall be
         equal to the net amount of such items that would have been allocated to
         each such Partner under the Agreed Allocations had the Required
         Allocations and the related Curative Allocation not otherwise been
         provided in this Section 6.1. Notwithstanding the preceding sentence,
         Required Allocations relating to (1) Nonrecourse Deductions shall not
         be taken into account pursuant to this Section 6.1(d)(ix) except to the
         extent that there has been a decrease in Partnership Minimum Gain and
         (2) Partner Nonrecourse Deductions shall not be taken into account
         pursuant to this Section 6.1(d)(ix) except to the extent that there has
         been a decrease in Partner Nonrecourse Debt Minimum Gain. Allocations
         pursuant to this Section 6.1(d)(ix)(A) shall only be made with respect
         to Required Allocations to the extent the Managing General Partner
         reasonably determines that such allocations will otherwise be
         inconsistent with the economic Agreement among the Partners. Further,
         allocations pursuant to this Section 6.1(d)(ix)(A) shall be deferred
         with respect to allocations pursuant to clauses (1) and (2) hereof to
         the extent the Managing General Partner reasonably determines that such
         allocations are likely to be offset by subsequent Required Allocations.

                                    (B) The Managing General Partner shall have
         reasonable discretion, with respect to each taxable period, to (1)
         apply the provisions of Section 6.1(d)(ix)(A) in whatever order is most
         likely to minimize the economic distortions that might otherwise result
         from the Required Allocations, and (2) divide all allocations pursuant
         to Section 6.1(d)(ix)(A) among the Partners in a manner that is likely
         to minimize such economic distortions.

         VI.2 ALLOCATIONS FOR TAX PURPOSES.

                  (a) Except as otherwise provided herein, for federal
income tax purposes, each item of income, gain, loss and deduction shall be
allocated among the Partners in the same manner as its correlative item of
"book" income, gain, loss or deduction is allocated pursuant to Section 6.1.

                  (b) In an attempt to eliminate Book-Tax Disparities
attributable to a Contributed Property or Adjusted Property, items of income,
gain, loss, depreciation, amortization and cost recovery deductions shall be
allocated for federal income tax purposes among the Partners as follows:

                           (i) (A) In the case of a Contributed Property, such
         items attributable thereto shall be allocated among the Partners in the
         manner provided under Section 704(c) of the Code that takes into
         account the variation between the Agreed Value of such property and
<PAGE>   193
                                                                     Exhibit 7-B
                                                                   Page 31 of 58

         its adjusted basis at the time of contribution; and (B) any item of
         Residual Gain or Residual Loss attributable to a Contributed Property
         shall be allocated among the Partners in the same manner as its
         correlative item of "book" gain or loss is allocated pursuant to
         Section 6.1.

                           (ii) (A) In the case of an Adjusted Property, such
         items shall (1) first, be allocated among the Partners in a manner
         consistent with the principles of Section 704(c) of the Code to take
         into account the Unrealized Gain or Unrealized Loss attributable to
         such property and the allocations thereof pursuant to Section 5.5(d)(i)
         or (ii), and (2) second, in the event such property was originally a
         Contributed Property, be allocated among the Partners in a manner
         consistent with Section 6.2(b)(i)(A); and (B) any item of Residual Gain
         or Residual Loss attributable to an Adjusted Property shall be
         allocated among the Partners in the same manner as its correlative item
         of "book" gain or loss is allocated pursuant to Section 6.1.

                           (iii) The Managing General Partner shall apply the
         principles of Treasury Regulation Section 1.704-3(d) to eliminate
         Book-Tax Disparities.

                           (c) The Managing General Partner shall have sole
         discretion to (i) adopt such conventions as it deems appropriate in
         determining the amount of depreciation, amortization and cost recovery
         deductions; (ii) make special allocations for federal income tax
         purposes of income (including, without limitation, gross income) or
         deductions; and (iii) amend the provisions of this Agreement as
         appropriate to reflect the proposal or promulgation of Treasury
         Regulations under Section 704(b) or Section 704(c) of the Code. The
         Managing General Partner may adopt such conventions, make such
         allocations and make such amendments to this Agreement as provided in
         this Section 6.2(c) only if such conventions, allocations or amendments
         would not have a material adverse effect on the Partners, and if such
         allocations are consistent with the principles of Section 704 of the
         Code.

                           (d) The Managing General Partner in its discretion
         may determine to depreciate or amortize the portion of an adjustment
         under Section 743(b) of the Code attributable to unrealized
         appreciation in any Adjusted Property (to the extent of the unamortized
         Book-Tax Disparity) using a predetermined rate derived from the
         depreciation or amortization method and useful life applied to the
         Partnership's common basis of such property, despite any inconsistency
         of such approach with Treasury Regulation Section 1.167(c)-l(a)(6) or
         the legislative history of Section 197 of the Code or Proposed Treasury
         Regulation Section 1.197-2(g)(3).

                           (e) Any gain allocated to the Partners upon the sale
         or other taxable disposition of any Partnership asset shall, to the
         extent possible, after taking into account other required allocations
         of gain pursuant to this Section 6.2, be characterized as Recapture
         Income in the same proportions and to the same extent as such Partners
         (or their predecessors in interest) have been allocated any deductions
         directly or indirectly giving rise to the treatment of such gains as
         Recapture Income.

                                                                   Page 32 of 58


                           (f) All items of income, gain, loss, deduction and
         credit recognized by the Partnership for federal income tax purposes
         and allocated to the Partners in accordance with the provisions hereof
         shall be determined without regard to any election under Section 754 of
         the Code which may be made by the Partnership; provided, however, that
         such allocations, once made, shall be adjusted as necessary or
         appropriate to take into account those adjustments permitted or
         required by Sections 734 and 743 of the Code.

                           (g) The Managing General Partner may adopt such
         methods of allocation of income, gain, loss or deduction between a
         transferor and a transferee of a Partner Interest as it determines
         necessary, to the extent permitted or required by Section 706 of the
         Code and the regulations or rulings promulgated thereunder.

         VI.3 DISTRIBUTIONS.

                  (a) Distribution of Available Cash in any Quarter shall
be made to the Partners at the times and in the aggregate amounts determined by
the Managing General Partner in its sole discretion. Except as provided in
Section 6.3(c), all distributions of Available Cash shall be made to the
Partners in accordance with their respective Percentage Interests. No
distribution of cash shall be made if and to the extent such distribution would
be prohibited by applicable law or by any loan agreement, security agreement,
mortgage, debt instrument or other agreement or obligation to which the
Partnership is a party or by which it is bound or its assets are subject. All
distributions required to be made under this Agreement shall be made subject to
Section 17-607 of the Delaware Act.

                  (b) The Managing General Partner may elect in any Quarter
to distribute to any Partner any property other than cash held by the
Partnership in the aggregate amount determined by the Managing General Partner
in its sole discretion; provided, however, the Managing General Partner may not
without the consent of the Special Limited Partner distribute any cash or other
property held by the Partnership to the Special Limited Partner pursuant to this
Section 6.3(b) if such distribution would reduce the Special Limited Partner's
Percentage Interest below 1.0%; provided further, no distribution pursuant to
this Section 6.3(b) may be made in any Quarter in which the Liquidation Date
occurs or any following Quarter.

                  (c) In the event of the dissolution and liquidation of
the Partnership, all distributions of cash or any other property shall be made
solely in accordance with, and subject to the terms and conditions of, Section
12.4.

                  (d) The Managing General Partner shall have the
discretion to treat taxes paid by the Partnership on behalf of, or amounts

                      MANAGEMENT AND OPERATION OF BUSINESS

         VII.1 MANAGEMENT.

                  (a) The Managing General Partner shall conduct, direct
and manage all activities of the Partnership. Except as otherwise expressly
provided in this Agreement, all management powers over the business and affairs
of the Partnership shall be exclusively vested in the Managing General Partner,
and no Limited Partner shall have any management power over the business and
affairs of the Partnership. In addition to the powers now or hereafter granted a
general partner of a limited partnership under applicable law or which are
granted to the Managing General Partner under any other provision of this
Agreement, the Managing General Partner, subject to Section 7.3, shall have full
power and authority to do all things and on such terms as it, in its sole
discretion, may deem necessary or appropriate to conduct the business of the
Partnership, to exercise all powers set forth in Section 2.5 and to effectuate
the purposes set forth in Section 2.4, including the following:

                           (i) the making of any expenditures, the lending or
         borrowing of money, the assumption or guarantee of, or other
         contracting for, indebtedness and other liabilities, the issuance of
         evidences of indebtedness and the incurring of any other obligations;

                           (ii) the making of tax, regulatory and other filings,
         or rendering of periodic or other reports to governmental or other
         agencies having jurisdiction over the business or assets of the
         Partnership;

                           (iii) the acquisition, disposition, mortgage, pledge,
         encumbrance, hypothecation or exchange of any or all of the assets of
         the Partnership or the merger or other combination of the Partnership
         with or into another Person;

                           (iv) the use of the assets of the Partnership
         (including cash on hand) for any purpose consistent with the terms of
         this Agreement, including the financing of the conduct of the
         operations of the Partnership Group, the lending of funds to other
         Persons (including the MLP, the General Partners and their Affiliates),
         the repayment of obligations of the MLP or any member of the
         Partnership Group and the making of capital contributions to any member
         of the Partnership Group;

                           (v) the negotiation, execution and performance of any
         contracts, conveyances or other instruments (including instruments that
         limit the liability of the Partnership under contractual arrangements
         to all or particular assets of the Partnership, with the other party to
         the contract to have no recourse against the General Partners or their
         assets other than its interest in the Partnership, even if same results
         in the terms of the transaction being less favorable to the Partnership
         than would otherwise be the case);

                           (vi) the distribution of Partnership cash;
<PAGE>   196
                                                                     Exhibit 7-B
                                                                   Page 34 of 58


                           (vii) the selection and dismissal of employees
         (including employees having titles such as "president," "vice
         president," "secretary" and "treasurer") and agents, outside attorneys,
         accountants, consultants and contractors and the determination of their
         compensation and other terms of employment or hiring;

                           (viii) the maintenance of such insurance for the
         benefit of the Partnership Group and the Partners (including the assets
         of the Partnership) as it deems necessary or appropriate;

                           (ix) the formation of, or acquisition of an interest
         in, and the contribution of property and the making of loans to, any
         further limited or general partnerships, joint ventures, corporations
         or other relationships;

                           (x) the control of any matters affecting the rights
         and obligations of the Partnership, including the bringing and
         defending of actions at law or in equity and otherwise engaging in the
         conduct of litigation and the incurring of legal expense and the
         settlement of claims and litigation; and

                           (xi) the indemnification of any Person against
         liabilities and contingencies to the extent permitted by law.

                  (b) Notwithstanding any other provision of this Agreement, the
MLP Agreement, the Delaware Act or any applicable law, rule or regulation, each
of the Partners agrees that the execution, delivery or performance by the
Managing General Partner, any Group Member or any Affiliate of any of them, of
this Agreement or any agreement authorized or permitted under this Agreement
[(including any agreement necessary or desirable in the event that the
Partnership, the Class A Limited Partner or any direct or indirect parent seeks
to make a public or private offering of interests therein)], shall not
constitute a breach by the Managing General Partner of any duty that the
Managing General Partner may owe the Partnership or the Limited Partners or the
Assignees or any other Persons under this Agreement (or any other agreements) or
of any duty stated or implied by law or equity.

         VII.2 CERTIFICATE OF LIMITED PARTNERSHIP.

         On March 16 , 1996, the Special Limited Partner caused the Certificate
of Limited Partnership to be filed with the Secretary of State of the State of
Delaware as required by the Delaware Act. The Managing General Partner shall use
all reasonable efforts to cause to be filed such other certificates or documents
as may be determined by the Managing General Partner in its sole discretion to
be reasonable and necessary or appropriate for the formation, continuation,
qualification and operation of a limited partnership (or a partnership in which
the limited partners have limited liability) in the State of Delaware or any
other state in which the Partnership may elect to do business or own property.
To the extent that such action is determined by the Managing General Partner in
its sole discretion to be reasonable and necessary or appropriate, the Managing
General Partner shall file amendments to and restatements of the Certificate of
Limited Partnership and do all things to maintain the Partnership as a limited
partnership (or a partnership or other entity
<PAGE>   197
                                                                     Exhibit 7-B
                                                                   Page 35 of 58


in which the limited partners have limited liability) under the laws of the
State of Delaware or of any other state in which the Partnership may elect to do
business or own property.

         VII.3 RESTRICTIONS ON MANAGING GENERAL PARTNER'S AUTHORITY.

                  (a) The Managing General Partner may not, without written
approval of the specific act by the Limited Partners or by other written
instrument executed and delivered by the Limited Partners subsequent to the date
of this Agreement, take any action in contravention of this Agreement,
including, except as otherwise provided in this Agreement, (i) committing any
act that would make it impossible to carry on the ordinary business of the
Partnership or (ii) possessing Partnership property, or assigning any rights in
specific Partnership property, for other than a Partnership purpose.

                  (b) The Managing General Partner may sell, exchange or
otherwise dispose of all or substantially all of the Partnership's assets in a
single transaction or a series of related transactions without the approval of
the Limited Partners.

         VII.4 REIMBURSEMENT OF THE GENERAL PARTNERS.

                  (a) Except as provided in this Section 7.4 and elsewhere in
this Agreement or in the MLP Agreement, the General Partners shall not be
compensated for their services as general partners of the MLP or any Group
Member.

                  (b) The General Partners shall be reimbursed on a monthly
basis, or such other reasonable basis as the Managing General Partner may
determine in its sole discretion, for (i) all direct and indirect expenses that
they incur or payments they make on behalf of the Partnership (including salary,
bonus, incentive compensation and other amounts paid to any Person, including
Affiliates of the General Partner, to perform services for the Partnership or
for the General Partners in the discharge of their duties to the Partnership),
and (ii) all other necessary or appropriate expenses allocable to the
Partnership or otherwise reasonably incurred by the Managing General Partner in
connection with operating the Partnership's business (including expenses
allocated to the General Partners by their Affiliates). The Managing General
Partner shall determine the expenses that are allocable to the Partnership in
any reasonable manner determined by the Managing General Partner in its sole
discretion. Reimbursements pursuant to this Section 7.4 shall be in addition to
any reimbursement to the General Partners as a result of indemnification
pursuant to Section 7.7.

                  (c) The Managing General Partner, in its sole discretion and
without the approval of the Limited Partners (who shall have no right to vote in
respect thereof), may propose and adopt on behalf of the Partnership employee
benefit plans, employee programs and employee practices for the benefit of
employees of the Managing General Partner, any Group Member or any Affiliate, or
any of them, in respect of services performed, directly or indirectly, for the
benefit of the Partnership Group. Expenses incurred by the Managing General
Partner in connection with any such plans, programs and practices shall be
reimbursed in accordance with Section 7.4(b). Any and all obligations of the
Managing General Partner under any employee benefit plans, employee programs

                                                                     Exhibit 7-B
                                                                   Page 36 of 58


or employee practices adopted by the Managing General Partner as permitted by
this Section 7.4(c) shall constitute obligations of the Managing General Partner
hereunder and shall be assumed by any successor Managing General Partner
approved pursuant to Section 11.1 or 11.2 or the transferee of or successor to
all of the Managing General Partner's Partner Interest as a general partner in
the Partnership pursuant to Section 4.2.

         VII.5 OUTSIDE ACTIVITIES.

                  (a) The General Partners and their Affiliates shall have the
right to engage in businesses of every type and description and other activities
for profit and to engage in and possess an interest in other business ventures
of any and every type or description, whether in businesses engaged in or
anticipated to be engaged in by any Group Member, independently or with others,
including business interests and activities in direct competition with the
business and activities of any Group Member, and none of the same shall
constitute a breach of this Agreement or any duty express or implied by law to
any Group Member or any Partner or Assignee. Neither any Group Member, any
Limited Partner nor any other Person shall have any rights by virtue of this
Agreement or the partnership relationship established hereby in any business
ventures of any Indemnitee.

                  (b) Notwithstanding anything to the contrary in this
Agreement, (i) the engaging in competitive activities by any Indemnitee in
accordance with the provisions of this Section 7.5 is hereby approved by the
Partnership and all Partners and (ii) it shall be deemed not to be a breach of
the General Partners' fiduciary duty (or any other obligation of any type
whatsoever of the General Partners) for any General Partner or for any Affiliate
of a General Partner to engage in such business interests and activities in
preference to or to the exclusion of the Partnership (including, without
limitation, the General Partners and their Affiliates shall have no obligation
to present business opportunities to the Partnership).

         VII.6 LOANS FROM THE GENERAL PARTNERS; LOANS OR CONTRIBUTIONS FROM THE
               PARTNERSHIP; CONTRACTS WITH AFFILIATES; CERTAIN RESTRICTIONS ON
               THE GENERAL PARTNERS.

                  (a) The General Partners or any of their Affiliates may lend
to the MLP or any Group Member, and the MLP or any Group Member may borrow from
the General Partners or any of their Affiliates, funds needed or desired by the
MLP or the Group Member for such periods of time and in such amounts as the
Managing General Partner may determine; provided, however, that in any such case
the lending party may not charge the borrowing party interest at a rate greater
than the rate that would be charged the borrowing party or impose terms less
favorable to the borrowing party than would be charged or imposed on the
borrowing party by unrelated lenders on comparable loans made on an arms'-length
basis (without reference to the lending party's financial abilities or
guarantees). The borrowing party shall reimburse the lending party for any costs
(other than any additional interest costs) incurred by the lending party in
connection with the borrowing of such funds. For purposes of this Section 7.6(a)
and Section 7.6(b), the term "Group Member" shall include any Affiliate of a
Group Member that is controlled by the Group Member.

                                                                     Exhibit 7-B
                                                                   Page 37 of 58


                  (b) The Partnership may lend or contribute to any Group
Member, the General Partners or any of their Affiliates and any Group Member,
the General Partners or any of their Affiliates may borrow from the Partnership,
funds on terms and conditions established in the sole discretion of the Managing
General Partner; provided, however, that the Partnership may not charge the
Group Member, General Partners or their Affiliates interest at a rate less than
the rate that would be charged to the Group Member, the General Partners or any
of their Affiliates by unrelated lenders on comparable loans. The foregoing
authority shall be exercised by the Managing General Partner in its sole
discretion and shall not create any right or benefit in favor of any Group
Member or any other Person.

                  (c) The Managing General Partner may itself, or may enter
into an Agreement with any of its Affiliates to, render services to a Group
Member or to the Managing General Partner in the discharge of its duties as a
general partner of the Partnership. Any services rendered to a Group Member by
the Managing General Partner (other than services it renders in its capacity as
Managing General Partner) or any of its Affiliates shall be on terms that are
fair and reasonable to the Partnership; provided, however, that the requirements
of this Section 7.6(c) shall be deemed satisfied as to (i) any transaction
approved by Special Approval, (ii) any transaction, the terms of which are no
less favorable to the Partnership Group than those generally being provided to
or available from unrelated third parties or (iii) any transaction that, taking
into account the totality of the relationships between the parties involved
(including other transactions that may be particularly favorable or advantageous
to the Partnership Group), is equitable to the Partnership Group. The provisions
of Section 7.4 shall apply to the rendering of services described in this
Section 7.6(c).

                  (d) Any Group Member may transfer assets to joint ventures,
other partnerships, corporations, limited liability companies or other business
entities in which it is or thereby becomes a participant upon such terms and
subject to such conditions as are consistent with this Agreement and applicable
law.

                  (e) Neither the General Partners nor any of their Affiliates
shall sell, transfer or convey any property to, or purchase any property from
the Partnership, directly or indirectly, except pursuant to transactions that
are fair and reasonable to the Partnership; provided, however, that the
requirements of this Section 7.6(e) shall be deemed to be satisfied as to (i)
the transactions effected pursuant to Sections 5.1(a) and 5.1(b), (ii) any
transaction approved by Special Approval, (iii) any transaction, the terms of
which are no less favorable to the Partnership than those generally being
provided to or available from unrelated third parties, or (iv) any transaction
that, taking into account the totality of the relationships between the parties
involved (including other transactions that may be particularly favorable or
advantageous to the Partnership), is equitable to the Partnership.

                  (f) The General Partners and their Affiliates will have no
obligation to permit any Group Member to use any facilities or assets of the
General Partners and their Affiliates, except as may be provided in contracts
entered into from time to time specifically dealing with such use, nor shall
there be any obligation on the part of the General Partners or their Affiliates
to enter into such contracts.

         VII.7 INDEMNIFICATION.

                  (a) To the fullest extent permitted by law but subject to the
limitations expressly provided in this Agreement, all Indemnitees shall be
indemnified and held harmless by the Partnership from and against any and all
losses, claims, damages, liabilities, joint or several, expenses (including
legal fees and expenses), judgments, fines, penalties, interest, settlements or
other amounts arising from any and all claims, demands, actions, suits or
proceedings, whether civil, criminal, administrative or investigative, in which
any Indemnitee may be involved, or is threatened to be involved, as a party or
otherwise, by reason of its status as an Indemnitee, provided, that in each case
the Indemnitee acted in good faith and in a manner that such Indemnitee
reasonably believed to be in, or not opposed to, the best interests of the
Partnership and, with respect to any criminal proceeding, had no reasonable
cause to believe its conduct was unlawful. The termination of any action, suit
or proceeding by judgment, order, settlement, conviction or upon a plea of nolo
contendere, or its equivalent, shall not create a presumption that the
Indemnitee acted in a manner contrary to that specified above. Any
indemnification pursuant to this Section 7.7 shall be made only out of the
assets of the Partnership, it being agreed that the General Partners shall not
be personally liable for such indemnification and shall have no obligation to
contribute or loan any monies or property to the Partnership to enable it to
effectuate such indemnification.

                  (b) To the fullest extent permitted by law, expenses
(including legal fees and expenses) incurred by an Indemnitee who is indemnified
pursuant to Section 7.7(a) in defending any claim, demand, action, suit or
proceeding shall, from time to time, be advanced by the Partnership prior to the
final disposition of such claim, demand, action, suit or proceeding upon receipt
by the Partnership of any undertaking by or on behalf of the Indemnitee to repay
such amount if it shall be determined that the Indemnitee is not entitled to be
indemnified as authorized in this Section 7.7.

                  (c) The indemnification provided by this Section 7.7 shall be
in addition to any other rights to which an Indemnitee may be entitled under any
agreement, pursuant to any vote of the Partners, as a matter of law or
otherwise, both as to actions in the Indemnitee's capacity as an Indemnitee and
as to actions in any other capacity, and shall continue as to an Indemnitee who
has ceased to serve in such capacity and shall inure to the benefit of the
heirs, successors, assigns and administrators of the Indemnitee.

                  (d) The Partnership may purchase and maintain (or reimburse
the Managing General Partner or its Affiliates for the cost of) insurance, on
behalf of the General Partners, their Affiliates and such other Persons as the
Managing General Partner shall determine, against any liability that may be
asserted against or expense that may be incurred by such Person in connection
with the Partnership's activities or such Person's activities on behalf of the
Partnership, regardless of whether the Partnership would have the power to
indemnify such Person against such liability under the provisions of this
Agreement.

                  (e) For purposes of this Section 7.7, the Partnership shall be
deemed to have requested an Indemnitee to serve as fiduciary of an employee
benefit plan whenever the performance by it of its duties to the Partnership
also imposes duties on, or otherwise involves services by, it to
<PAGE>   201
                                                                     Exhibit 7-B
                                                                   Page 39 of 58


the plan or participants or beneficiaries of the plan; excise taxes assessed on
an Indemnitee with respect to an employee benefit plan pursuant to applicable
law shall constitute "fines" within the meaning of Section 7.7(a); and action
taken or omitted by it with respect to any employee benefit plan in the
performance of its duties for a purpose reasonably believed by it to be in the
interest of the participants and beneficiaries of the plan shall be deemed to be
for a purpose which is in, or not opposed to, the best interests of the
Partnership.

                  (f) In no event may an Indemnitee subject the Limited Partners
to personal liability by reason of the indemnification provisions set forth in
this Agreement.

                  (g) An Indemnitee shall not be denied indemnification in
whole or in part under this Section 7.7 because the Indemnitee had an interest
in the transaction with respect to which the indemnification applies if the
transaction was otherwise permitted by the terms of this Agreement.

                  (h) The provisions of this Section 7.7 are for the benefit of
the Indemnitees, their heirs, successors, assigns and administrators and shall
not be deemed to create any rights for the benefit of any other Persons.

                  (i) No amendment, modification or repeal of this Section 7.7
or any provision hereof shall in any manner terminate, reduce or impair (i) the
right of any Indemnitee to be indemnified by the Partnership, or (ii) the
obligations of the Partnership to indemnify any such Indemnitee under and in
accordance with the provisions of this Section 7.7 as in effect immediately
prior to such amendment, modification or repeal with respect to claims arising
from or relating to matters occurring, in whole or in part, prior to such
amendment, modification or repeal, regardless of when such claims may arise or
be asserted.

         VII.8 LIABILITY OF INDEMNITEES.

                  (a) Notwithstanding anything to the contrary set forth in
this Agreement, no Indemnitee shall be liable for monetary damages to the
Partnership, the Limited Partners, the Assignees or any other Persons who have
acquired Partner Interests, for losses sustained or liabilities incurred as a
result of any act or omission if such Indemnitee acted in good faith.

                  (b) Subject to its obligations and duties as Managing
General Partner set forth in Section 7.1(a), the Managing General Partner may
exercise any of the powers granted to it by this Agreement and perform any of
the duties imposed upon it hereunder either directly or by or through its
agents, and the General Partners shall not be responsible for any misconduct or
negligence on the part of any such agent appointed by the Managing General
Partner in good faith.

                  (c) Any amendment, modification or repeal of this Section 7.8
or any provision hereof shall be prospective only and shall not in any way
affect the limitations on liability under this Section 7.8 as in effect
immediately prior to such amendment, modification or repeal with respect to
claims arising from or relating to matters occurring, in whole or in part, prior
to such amendment, modification or repeal, regardless of when such claims may
arise or be asserted.

                                                                   Page 40 of 58


         VII.9 RESOLUTION OF CONFLICTS OF INTEREST.

                  (a) Unless otherwise expressly provided in this Agreement
whenever a potential conflict of interest exists or arises between one of the
General Partners or any of its Affiliates, on the one hand, and the Partnership,
the MLP, any Partner or any Assignee, on the other, any resolution or course of
action by the General Partners or their Affiliates in respect of such conflict
of interest shall be permitted and deemed approved by all Partners, and shall
not constitute a breach of this Agreement of any agreement contemplated herein,
or of any duty stated or implied by law or equity, if the resolution or course
of action is, or by operation of this Agreement is deemed to be, fair and
reasonable to the Partnership. The Managing General Partner shall be authorized
but not required in connection with its resolution of such conflict of interest
to seek Special Approval of such resolution. Any conflict of interest and any
resolution of such conflict of interest shall be conclusively deemed fair and
reasonable to the Partnership if such conflict of interest or resolution is (i)
approved by Special Approval, (ii) on terms no less favorable to the Partnership
than those generally being provided to or available from unrelated third parties
or (iii) fair to the Partnership, taking into account the totality of the
relationships between the parties involved (including other transactions that
may be particularly favorable or advantageous to the Partnership). The Managing
General Partner may also adopt a resolution or course of action that has not
received Special Approval. The Managing General Partner (including the Audit
Committee in connection with Special Approval) shall be authorized in connection
with its determination of what is "fair and reasonable" to the Partnership and
in connection with its resolution of any conflict of interest to consider (A)
the relative interests of any party to such conflict, agreement, transaction or
situation and the benefits and burdens relating to such interest; (B) any
customary or accepted industry practices and any customary or historical
dealings with a particular Person; (C) any applicable generally accepted
accounting practices or principles; and (D) such additional factors as the
Managing General Partner (including the Audit Committee) determines in its sole
discretion to be relevant, reasonable or appropriate under the circumstances.
Nothing contained in this Agreement, however, is intended to nor shall it be
construed to require the Managing General Partner (including the Audit
Committee) to consider the interests of any Person other than the Partnership.
In the absence of bad faith by the Managing General Partner, the resolution,
action or terms so made, taken or provided by the Managing General Partner with

Partner delivers to the Partnership an Opinion of Counsel ("Withdrawal Opinion
of Counsel") that such withdrawal (following the selection of the successor

partner of the other Group Members. If a Person is elected as a successor
General Partner in accordance with the terms of this Section 11.2, such Person
shall, upon admission pursuant to Section 10.3, automatically become the
successor general partner of the other Group Members. Any successor General
Partner elected in accordance with the terms of this Section 11.2 shall be
subject to the provisions of Section 10.3.

purchased by the successor to the Departing Partner for cash in an amount equal
to the fair market value of such Departing Partner"s Partner Interest, such
amount to be determined and payable as of the effective date of its departure.
Such purchase shall be a condition to the admission to the Partnership of the
successor as a General Partner. Any successor General Partner shall indemnify
the Departing Partner as to all debts and liabilities of the Partnership arising
on or after the effective date of the withdrawal or removal of the Departing
Partner.

                  For purposes of this Section 11.3(a), the fair market value of
the Departing Partners' Partner Interest shall be determined by agreement
between the Departing Partner and its successor or, failing agreement within 30
days after the effective date of such Departing Partner"s departure, by an
independent investment banking firm or other independent expert selected by the
Departing Partner and its successor, which, in turn, may rely on other experts,
and the determination of which shall be conclusive as to such matter. If such
parties cannot agree upon one independent investment banking firm or other
independent expert within 45 days after the effective date of such departure,
then the Departing Partner shall designate an independent investment banking
firm or other independent expert, the Departing Partner"s successor shall
designate an independent investment banking firm or other independent expert,
and such firms or experts shall mutually select a third independent investment
banking firm or independent expert, which third independent investment banking
firm or other independent expert shall determine the fair market value of the
Departing Partner"s Partner Interest.

                  (b) The Departing Partner shall be entitled to receive
all reimbursements due such Departing Partner pursuant to Section 7.4, including
any employee-related liabilities (including severance liabilities), incurred in
connection with the termination of any employees employed by such Departing
Partner for the benefit of the Partnership.

                  (c) Any successor General Partner shall indemnify the
Departing Partner as to all debts and liabilities of the Partnership arising on
or after the effective date of the withdrawal or removal of the Departing
Partner.

         XI.4 WITHDRAWAL OF THE LIMITED PARTNER.

         Except as provided in Section 4.5, no Limited Partner shall have the
right to withdraw from the Partnership without the prior written consent of the
Managing General Partner, which may be granted or withheld in its sole
discretion.

                  (b) an Event of Withdrawal of the Managing General
Partner as provided in Section 11.1(a) (other than Section 11.1(a)(ii)), unless
a successor is elected and an Opinion of Counsel is received as provided in

                  (c) an election to dissolve the Partnership by the Managing

         XII.2 CONTINUATION OF THE BUSINESS OF THE PARTNERSHIP AFTER
DISSOLUTION.

         Upon dissolution of the Partnership following an Event of Withdrawal
caused by the withdrawal or removal of the Managing General Partner as provided
in Section 11.1(a)(i) or (iii) and following a failure of the Class A Limited
Partners to appoint a successor Managing General Partner as provided in Section
11.1 or 11.2, then within 90 days thereafter, all of the Class A Limited
Partners may elect to reconstitute the Partnership and continue its business on
the terms and conditions set forth in this Agreement by forming a new limited
partnership on terms identical to those set forth in this Agreement and having
as a Managing General Partner a Person approved by the majority of the Class A
Limited Partners. Upon any such election by the Class A Limited Partners, all
Partners shall be bound thereby and shall be deemed to have approved same.
Unless such an election is made within the applicable time period as set forth
above, the Partnership shall conduct only activities necessary to wind up its
affairs. If such an election is so made, then:

                           (i) the reconstituted Partnership shall continue
         until the end of the term set forth in Section 2.7 unless earlier
         dissolved in accordance with this Article XII;

                           (ii) if the successor General Partner is not the
         former Managing General Partner, then the interest of the former
         Managing General Partner shall be purchased by the successor General
         Partner; and

                           (iii) all necessary steps shall be taken to cancel
         this Agreement and the Certificate of Limited Partnership and to enter
         into and, as necessary, to file a new partnership agreement and
         certificate of limited partnership, and the successor General Partner
         may for this purpose exercise the powers of attorney granted the
         Managing General Partner pursuant to Section 2.6; provided, that the
         right to approve a successor General Partner and to reconstitute and to
         continue the business of the Partnership shall not exist and may not be
         exercised unless the Partnership has received an Opinion of Counsel
         that (x) the

         exercise of the right would not result in the loss of limited liability
         of the Limited Partners and (y) neither the Partnership, the
         reconstituted limited partnership nor any Group Member would be treated
         as an association taxable as a corporation or otherwise be taxable as
         an entity for federal income tax purposes upon the exercise of such
         right to continue.

         XII.3 LIQUIDATOR.

         Upon dissolution of the Partnership, unless the Partnership is
continued under an election to reconstitute and continue the Partnership
pursuant to Section 12.2, the Managing General Partner shall select one or more
Persons to act as Liquidator. The Liquidator (if other than the Managing General
Partner) shall be entitled to receive such compensation for its services as may
be approved by the Class A Limited Partners. The Liquidator (if other than the
Managing General Partner) shall agree not to resign at any time without 15 days'
prior notice and may be removed at any time, with or without cause, by notice of
removal approved by a majority in interest of the Class A Limited Partners. Upon
dissolution, removal or resignation of the Liquidator, a successor and
substitute Liquidator (who shall have and succeed to all rights, powers and
duties of the original Liquidator) shall within 30 days thereafter be approved
by a majority in interest of the Class A Limited Partners. The right to approve
a successor or substitute Liquidator in the manner provided herein shall be
deemed to refer also to any such successor or substitute Liquidator approved in
the manner herein provided. Except as expressly provided in this Article XII,
the Liquidator approved in the manner provided herein shall have and may
exercise, without further authorization or consent of any of the parties hereto,
all of the powers conferred upon the Managing General Partner under the terms of
this Agreement (but subject to all of the applicable limitations, contractual or
otherwise, upon the exercise of such powers) to the extent necessary or
desirable in the good faith judgment of the Liquidator to carry out the duties
and functions of the Liquidator hereunder for and during such period of time as
shall be reasonably required in the good faith judgment of the Liquidator to
complete the winding up and liquidation of the Partnership as provided for
herein.

         XII.4 LIQUIDATION.

         The Liquidator shall proceed to dispose of the assets of the
Partnership, discharge its liabilities, and otherwise wind up its affairs in
such manner and over such period as the Liquidator determines to be in the best
interest of the Partners, subject to Section 17-804 of the Delaware Act and the
following:

                  (a) Disposition of Assets. The assets may be disposed of
by public or private sale or by distribution in kind to one or more Partners on
such terms as the Liquidator and such Partner or Partners may agree. If any
property is distributed in kind, the Partner receiving the property shall be
deemed for purposes of Section 12.4(c) to have received cash equal to its fair
market value; and contemporaneously therewith, appropriate cash distributions
must be made to the other Partners. The Liquidator may, in its absolute
discretion, defer liquidation of the Partnership's assets for a reasonable time
if it determines that an immediate sale of all or part of the Partnership's
assets would be impractical or would cause undue loss to the Partners. The
Liquidator may, in its absolute

                                                                     Exhibit 7-B
                                                                   Page 51 of 58


discretion, distribute the Partnership's assets, in whole or in part, in kind if
it determines that a sale would be impractical or would cause undue loss to the
partners.

                  (b) Discharge of Liabilities. Liabilities of the
Partnership include amounts owed to Partners otherwise than in respect of their
distribution rights under Article VI. With respect to any liability that is
contingent or is otherwise not yet due and payable, the Liquidator shall either
settle such claim for such amount as it thinks appropriate or establish a
reserve of cash or other assets to provide for its payment. When paid, any
unused portion of the reserve shall be distributed as additional liquidation
proceeds.

                  (c) Liquidation Distributions. All property and all cash
in excess of that required to discharge liabilities as provided in Section
12.4(b) shall be distributed to the Partners in accordance with, and to the
extent of, the positive balances in their respective Capital Accounts, as
determined after taking into account all Capital Account adjustments (other than
those made by reason of distributions pursuant to this Section 12.4(c)) for the
taxable year of the Partnership during which the liquidation of the Partnership
occurs (with such date of occurrence being determined pursuant to Treasury
Regulation, Section 1.704-1(b)(2)(ii)(g)), and such distribution shall be made
by the end of such taxable year (or, if later, within 90 days after said date of
such occurrence).

         XII.5 CANCELLATION OF CERTIFICATE OF LIMITED PARTNERSHIP.

         Upon the completion of the distribution of Partnership cash and
property as provided in Section 12.4 in connection with the liquidation of the
Partnership, the Partnership shall be terminated and the Certificate of Limited
Partnership and all qualifications of the Partnership as a foreign limited
partnership in jurisdictions other than the State of Delaware shall be canceled
and such other actions as may be necessary to terminate the Partnership shall be
taken.

         XII.6 RETURN OF CAPITAL CONTRIBUTIONS.

         Except as provided in Section 12.8, the General Partners shall not be
personally liable for, and shall have no obligation to contribute or loan any
monies or property to the Partnership to enable it to effectuate, the return of
the Capital Contributions of any Limited Partner, or any portion thereof, it
being expressly understood that any such return shall be made solely from
Partnership assets.

         XII.7 WAIVER OF PARTITION.

         To the maximum extent permitted by law, each Partner hereby waives any
right to partition of the Partnership property.

         XII.8 CAPITAL ACCOUNT RESTORATION.

         No Limited Partner shall have any obligation to restore any negative
balance in its Capital Account upon liquidation of the Partnership. The Managing
General Partner shall be obligated to restore any negative balance in its
Capital Account upon liquidation of its interest in the Partnership
<PAGE>   214
                                                                     Exhibit 7-B

by the end of the taxable year of the Partnership during which such liquidation
occurs, or, if later, within 90 days after the date of such liquidation.

                                    ARTICLE I

                                  Stockholders

               Section 1.1. Annual Meetings. An annual meeting of stockholders
shall be held for the election of directors at such date, time and place, either
within or without the State of Delaware, as may be designated by resolution of
the Board of Directors from time to time. Any other proper business may be
transacted at the annual meeting.

               Section 1.2. Special Meetings. Special meetings of stockholders
for any purpose or purposes may be called at any time by the Board of Directors,
or by a committee of the Board of Directors that has been duly designated by the
Board of Directors and whose powers and authority, as expressly provided in a
resolution of the Board of Directors, include the power to call such meetings,
but such special meetings may not be called by any other person or persons.

               Section 1.3. Notice of Meetings. Whenever stockholders are
required or permitted to take any action at a meeting, a written notice of the
meeting shall be given that shall state the place, date and hour of the meeting
and, in the case of a special meeting, the purpose or purposes for which the
meeting is called. Unless otherwise provided by law, the certificate of
incorporation or these bylaws, the written notice of any meeting shall be given
not less than ten (10) nor more than sixty (60) days before the date of the
meeting to each stockholder entitled to vote at such meeting. If mailed, such
notice shall be deemed to be given when deposited in the United States mail,
postage prepaid, directed to the stockholder at his address as it appears on the
records of the corporation.

               Section 1.4. Adjournments. Any meeting of stockholders, annual or
special, may adjourn from time to time to reconvene at the same or some other
place, and notice need not be given of any such adjourned meeting if the time
and place thereof are announced at the meeting at which the adjournment is
taken. At the adjourned meeting the corporation may transact any business which
might have been transacted at the original meeting. If the adjournment is for
more than thirty (30) days, or if after the adjournment a new record date is
fixed for the adjourned meeting, notice of the adjourned meeting shall be given
to each stockholder of record entitled to vote at the meeting.

               Section 1.5. Quorum. Except as otherwise provided by law, the
certificate of incorporation or these bylaws, at each meeting of stockholders
the presence in person or by proxy of the holders of a majority in voting power
of the outstanding shares of stock entitled to vote at the meeting shall be
necessary and sufficient to constitute a quorum. In the absence of a quorum, the
<PAGE>   222
                                                                     Exhibit 8-B
                                                                    Page 2 of 15


stockholders so present may, by majority vote, adjourn the meeting from time to
time in the manner provided in Section 1.4 of these bylaws until a quorum shall
attend. Shares of its own stock belonging to the corporation or to another
corporation, if a majority of the shares entitled to vote in the election of
directors of such other corporation is held, directly or indirectly, by the
corporation, shall neither be entitled to vote nor be counted for quorum
purposes; provided, however, that the foregoing shall not limit the right of the
corporation or any subsidiary of the corporation to vote stock, including but
not limited to its own stock, held by it in a fiduciary capacity.

               Section 1.6. Organization. Meetings of stockholders shall be
presided over by the Chairman of the Board, if any, or in his absence by the
Vice Chairman of the Board, if any, or in his absence by the President, or in
his absence by a Vice President, or in the absence of the foregoing persons by a
chairman designated by the Board of Directors, or in the absence of such
designation by a chairman chosen at the meeting. The Secretary shall act as
secretary of the meeting, but in his absence the person presiding over the
meeting may appoint any person to act as secretary of the meeting. The person
presiding over the meeting shall announce at the meeting of stockholders the
date and time of the opening and the closing of the polls for each matter upon
which the stockholders will vote.

               Section 1.7. Voting; Proxies. Except as otherwise provided by the
certificate of incorporation, each stockholder entitled to vote at any meeting
of stockholders shall be entitled to one (1) vote for each share of stock held
by him which has voting power upon the matter in question. Each stockholder
entitled to vote at a meeting of stockholders or to express consent or dissent
to corporate action in writing without a meeting may authorize another person or
persons to act for him by proxy, but no such proxy shall be voted or acted upon
after three (3) years from its date, unless the proxy provides for a longer
period. A proxy shall be irrevocable if it states that it is irrevocable and if,
and only as long as, it is coupled with an interest sufficient in law to support
an irrevocable power. A stockholder may revoke any proxy which is not
irrevocable by attending the meeting and voting in person or by filing with the
Secretary of the corporation an instrument in writing revoking the proxy or by
delivering a proxy in accordance with applicable law bearing a later date to the
Secretary of the corporation. Voting at meetings of stockholders need not be by
written ballot. At all meetings of stockholders for the election of directors a
plurality of the votes cast shall be sufficient to elect. All other elections
and questions shall, unless otherwise provided by law, the certificate of
incorporation or these bylaws, be decided by the affirmative vote of the holders
of a majority in voting power of the shares of stock which are present in person
or by proxy and entitled to vote thereon.

               Section 1.8. Fixing Date for Determination of Stockholders of
Record. In order that the corporation may determine the stockholders entitled to
notice of or to vote at any meeting of stockholders or any adjournment thereof,
or to express consent to corporate action in writing without a meeting, or
entitled to receive payment of any dividend or other distribution or allotment
of any rights, or entitled to exercise any rights in respect of any change,
conversion or exchange of stock or for the purpose of any other lawful action,
the Board of Directors may fix a record date, which record date shall not
precede the date upon which the resolution fixing the record date is

adopted by the Board of Directors, and which record date: (i) in the case of
determination of stockholders entitled to vote at any meeting of stockholders or
adjournment thereof, shall, unless otherwise required by law, not be more than
sixty (60) nor less than ten (10) days before the date of such meeting; (ii) in
the case of determination of stockholders entitled to express consent to
corporate action in writing without a meeting, shall not be more than ten (10)
days from the date upon which the resolution fixing the record date is adopted
by the Board of Directors; and (iii) in the case of determination of
stockholders for the purpose of any other lawful action, shall not be more than
sixty (60) days prior to such other action. If no record date is fixed: (iv) the
record date for determining stockholders entitled to notice of or to vote at a
meeting of stockholders shall be at the close of business on the day next
preceding the day on which notice is given, or, if notice is waived, at the
close of business on the day next preceding the day on which the meeting is
held; (v) the record date for determining stockholders entitled to express
consent to corporate action in writing without a meeting, when no prior action
of the Board of Directors is required by law, shall be the first date on which a
signed written consent setting forth the action taken or proposed to be taken is
delivered to the corporation in accordance with applicable law, or, if prior
action by the Board of Directors is required by law, shall be at the close of
business on the day on which the Board of Directors adopts the resolution taking
such prior action; and (vi) the record date for determining stockholders for the
purpose of any other lawful action, shall be at the close of business on the day
on which the Board of Directors adopts the resolution relating thereto. A
determination of stockholders of record entitled to notice of or to vote at a
meeting of stockholders shall apply to any adjournment of the meeting; provided,
however, that the Board of Directors may fix a new record date for the adjourned
meeting.

               Section 1.9. List of Stockholders Entitled to Vote. The Secretary
shall prepare and make, at least ten (10) days before every meeting of
stockholders, a complete list of the stockholders entitled to vote at the
meeting, arranged in alphabetical order, and showing the address of each
stockholder and the number of shares registered in the name of each stockholder.
Such list shall be open to the examination of any stockholder, for any purpose
germane to the meeting, during ordinary business hours, for a period of at least
ten (10) days prior to the meeting, either at a place within the city where the
meeting is to be held, which place shall be specified in the notice of the
meeting, or, if not so specified, at the place where the meeting is to be held.
The list shall also be produced and kept at the time and place of the meeting
during the whole time thereof and may be inspected by any stockholder who is
present. Upon the willful neglect or refusal of the directors to produce such a
list at any meeting for the election of directors, they shall be ineligible for
election to any office at such meeting. Except as otherwise provided by law, the
stock ledger shall be the only evidence as to who are the stockholders entitled
(i) to examine the stock ledger, the list of stockholders entitled to vote at
the meeting or the books of the corporation, (ii) to vote in person or by proxy
at any meeting of stockholders, or (iii) to express consent or dissent to
corporate action in writing without a meeting.

               Section 1.10. Action By Consent of Stockholders. Unless otherwise
restricted by the certificate of incorporation, any action required or permitted
to be taken at any annual or special meeting of the stockholders may be taken
without a meeting, without prior notice and without a
<PAGE>   224
                                                                     Exhibit 8-B
                                                                    Page 4 of 15


vote, if a consent or consents in writing, setting forth the action so taken,
shall be signed by the holders of outstanding stock having not less than the
minimum number of votes that would be necessary to authorize or take such action
at a meeting at which all shares entitled to vote thereon were present and voted
and shall be delivered (by hand or by certified or registered mail, return
receipt requested) to the corporation by delivery to its registered office in
the State of Delaware, its principal place of business, or an officer or agent
of the corporation having custody of the book in which minutes of proceedings of
meetings of stockholders are recorded. Prompt notice of the taking of the
corporate action without a meeting by less than unanimous written consent shall
be given to those stockholders who have not consented in writing.

               Section 1.11. Inspectors of Election. The corporation may, and
shall if required by law, in advance of any meeting of stockholders, appoint one
(1) or more inspectors of election, who may be employees of the corporation, to
act at the meeting or any adjournment thereof and to make a written report
thereof. The corporation may designate one (1) or more persons as alternate
inspectors to replace any inspector who fails to act. In the event that no
inspector so appointed or designated is able to act at a meeting of the
stockholders, the person presiding at the meeting shall appoint one (1) or more
inspectors to act at the meeting. Each inspector, before entering upon the
discharge of his or her duties, shall take and sign an oath to execute
faithfully the duties of inspector with strict impartiality and according to the
best of his or her ability. The inspector or inspectors so appointed or
designated shall (i) ascertain the number of shares of capital stock of the
corporation outstanding and the voting power of each such share, (ii) determine
the shares of capital stock of the corporation represented at the meeting and
the validity of proxies and ballots, (iii) count all votes and ballots, (iv)
determine and retain for a reasonable period a record of the disposition of any
challenges made to any determination by the inspectors, and (v) certify their
determination of the number of shares of capital stock of the corporation
represented at the meeting and such inspector's or inspectors' count of all
votes and ballots. Such certification and report shall specify such other
information as may be required by law. In determining validity and counting of
proxies and ballots cast at any meeting of stockholders of the corporation, the
inspectors may consider such information as is permitted by applicable law. No
person who is a candidate for an office at an election may serve as an inspector
at such election.

               Section 1.12. Conduct of Meetings. The Board of Directors of the
corporation may adopt by resolution such rules and regulations for the conduct
of the meeting of stockholders as it shall deem appropriate. Except to the
extent inconsistent with such rules and regulations as adopted by the Board of
Directors, the person presiding over any meeting of stockholders shall have the
right and authority to prescribe such rules, regulations and procedures and to
do all such acts as, in the judgment of such person, are appropriate for the
proper conduct of the meeting. Such rules, regulations or procedures, whether
adopted by the Board of Directors or prescribed by the person presiding over the
meeting, may include, without limitation, the following: (i) the establishment
of an agenda or order of business for the meeting; (ii) rules and procedures for
maintaining order at the meeting and the safety of those present; (iii)
limitations on attendance at or participation in the meeting to stockholders of
record of the corporation, their duly authorized and constituted proxies or such
other persons as the person presiding over the meeting shall determine; (iv)
restrictions on

entry to the meeting after the time fixed for the commencement thereof; and (v)
limitations on the time allotted to questions or comments by participants.
Unless and to the extent determined by the Board of Directors or the person
presiding over the meeting, meetings of stockholders shall not be required to be
held in accordance with the rules of parliamentary procedure.

                                   ARTICLE II

                               Board of Directors

               Section 2.1. Number; Qualifications. The Board of Directors shall
consist of one (1) or more members. The number of members comprising the Board
of Directors initially shall be the number of persons named as directors in the
certificate of incorporation (or if no person is so named, the number of persons
elected by the Incorporator). The number of members comprising the Board of
Directors thereafter shall be determined from time to time by resolution of the
Board of Directors. Directors need not be stockholders.

               Section 2.2. Election; Resignation; Removal; Vacancies. The Board
of Directors initially shall consist of the person or persons named as Directors
in the certificate of incorporation (or, if no person is so named, the person or
persons elected by the Incorporator), and each director so elected shall hold
office until his successor is elected and qualified or until his earlier death,
resignation, or removal. At the first annual meeting of stockholders and at each
annual meeting thereafter, the stockholders shall elect directors each of whom
shall hold office until his successor is elected and qualified or until his
earlier death, resignation, or removal. Any director may resign at any time upon
written notice to the corporation. Any newly created directorship or any vacancy
occurring in the Board of Directors for any cause may be filled by a majority of
the remaining members of the Board of Directors, although such majority is less
than a quorum, or by a plurality of the votes cast at a meeting of stockholders,
and each director so elected shall hold office until the expiration of the term
of office of the director whom he has replaced, or until his successor is
elected and qualified, or until his earlier death, resignation, or removal.

               Section 2.3. Regular Meetings. Regular meetings of the Board of
Directors may be held at such places within or without the State of Delaware and
at such times as the Board of Directors may from time to time determine, and if
so determined notices thereof need not be given.

               Section 2.4. Special Meetings. Special meetings of the Board of
Directors may be held at any time or place within or without the State of

by any member of the Board of Directors. Notice of a special meeting of the
Board of Directors shall be given by the person or persons calling the meeting
at least twenty-four (24) hours before the special meeting.

               Section 2.5. Telephonic Meetings Permitted. Members of the Board
of Directors, or any committee designated by the Board of Directors, may
participate in a meeting thereof by means of conference telephone or similar
communications equipment by means of which all persons

participating in the meeting can hear each other, and participation in a meeting
pursuant to this bylaw shall constitute presence in person at such meeting.

               Section 2.6. Quorum; Vote Required for Action. At all meetings of
the Board of Directors a majority of the whole Board of Directors shall
constitute a quorum for the transaction of business. Except in cases in which
the certificate of incorporation, these bylaws or applicable law otherwise
provides, the vote of a majority of the directors present at a meeting at which
a quorum is present shall be the act of the Board of Directors.

               Section 2.7. Organization. Meetings of the Board of Directors
shall be presided over by the Chairman of the Board, if any, or in his absence
by the Vice Chairman of the Board, if any, or in his absence by the President,
or in the absence of the foregoing persons by a chairman chosen at the meeting.
The Secretary shall act as secretary of the meeting, but in his absence the
person presiding over the meeting may appoint any person to act as secretary of
the meeting.

               Section 2.8. Informal Action by Directors. Unless otherwise
restricted by the certificate of incorporation or these bylaws, any action
required or permitted to be taken at any meeting of the Board of Directors, or
of any committee thereof, may be taken without a meeting if all members of the
Board of Directors or such committee, as the case may be, consent thereto in
writing, and the writing or writings are filed with the minutes of proceedings
of the Board of Directors or committee.

                                   ARTICLE III

                                   Committees

               Section 3.1. Committees. The Board of Directors may, by
resolution passed by a majority of the whole Board of Directors, designate one
(1) or more committees, each committee to consist of one (1) or more of the
directors of the corporation. The Board of Directors may designate one (1) or
more directors as alternate members of any committee, who may replace any absent
or disqualified member at any meeting of the committee. In the absence or
disqualification of a member of the committee, the member or members thereof
present at any meeting and not disqualified from voting, whether or not he or
they constitute a quorum, may unanimously appoint another member of the Board of
Directors to act at the meeting in place of any such absent or disqualified
member. Any such committee, to the extent permitted by law and to the extent
provided in the resolution of the Board of Directors, shall have and may
exercise all the powers and authority of the Board of Directors in the
management of the business and affairs of the corporation, and may authorize the
seal of the corporation to be affixed to all papers which may require it.

               Section 3.2. Committee Rules. Unless the Board of Directors
otherwise provides, each committee designated by the Board of Directors may
make, alter and repeal rules for the conduct of its business. In the absence of
such rules each committee shall conduct its business in the same manner as the
Board of Directors conducts its business pursuant to Article II of these bylaws.

the Board and a Vice Chairman of the Board from among its members. The Board of
Directors may also choose one (1) or more Vice Presidents, one (1) or more

Each such officer shall hold office until the first meeting of the Board of
Directors after the annual meeting of stockholders next succeeding his election,
and until his successor is elected and qualified or until his earlier death,
resignation, or removal. Any officer may resign at any time upon written notice
to the corporation. The Board of Directors may remove any officer with or
without cause at any time, but such removal shall be without prejudice to the
contractual rights of such officer, if any, with the corporation. Any number of
offices may be held by the same person. Any vacancy occurring in any office of
the corporation by death, resignation, removal, or otherwise may be filled for
the unexpired portion of the term by the Board of Directors at any regular or
special meeting.

               Section 4.2.  Powers and Duties of Executive Officers.

               (i) President. The President shall be the chief executive officer
of the corporation. Subject to the provisions of the certificate of
incorporation, these bylaws, and the direction of the Board of Directors, the

                                    ARTICLE V

                                      Stock

               Section 5.1. Certificates. Every holder of stock shall be
entitled to have a certificate signed by or in the name of the corporation by
the Chairman or Vice Chairman of the Board of Directors, if any, or the
President or a Vice President, and by the Treasurer or an Assistant Treasurer,
or the Secretary or an Assistant Secretary, of the corporation certifying the
number of shares owned by him in the corporation. Any of or all the signatures
on the certificate may be a facsimile. In case any officer, transfer agent, or
registrar who has signed or whose facsimile signature has been placed upon a
certificate shall have ceased to be such officer, transfer agent, or registrar
before such certificate is issued, it may be issued by the corporation with the
same effect as if he were such officer, transfer agent, or registrar at the date

Issuance of New Certificates. The corporation may issue a new certificate of
stock in the place of any certificate theretofore issued by it, alleged to have
been lost, stolen or destroyed, and the corporation may require the owner of the
lost, stolen or destroyed certificate, or his legal representative, to give the
corporation a bond sufficient to indemnify it against any claim that may be made
against it on account of the alleged loss, theft or destruction of any such
certificate or the issuance of such new certificate.

                                                                    Page 9 of 15


involved in any threatened, pending, or completed action, suit or proceeding,
whether civil, criminal, administrative or investigative (a "proceeding") by
reason of the fact that he, or a person for whom he is the legal representative,
is or was a director or officer of the corporation or is or was serving at the
request of the corporation as a director, officer, employee or agent of another
corporation or of a partnership, joint venture, trust, other enterprise or
non-profit entity, including service with respect to employee benefit plans (an
"indemnitee"), against all liability and loss suffered and expenses (including
attorneys' fees) reasonably incurred by such indemnitee. The corporation shall
be required to indemnify an indemnitee in connection with a proceeding (or part
thereof) initiated by such indemnitee only if the initiation of such proceeding
(or part thereof) by the indemnitee was authorized by the Board of Directors of
the corporation.

               Section 6.2. Advancement of Expenses. The corporation shall pay
the expenses (including attorneys' fees) incurred by an indemnitee in defending
any proceeding referred to in Section 6.1 in advance of its final disposition;
provided, however, that the payment of expenses incurred by an indemnitee in
advance of the final disposition of such proceeding shall be made only upon
receipt of an undertaking by the indemnitee to repay all amounts advanced if it
should ultimately be determined that the indemnitee is not entitled to be
indemnified under this Article or otherwise.

               Section 6.3. Claims. If a claim for indemnification or
advancement of expenses under this Article is not paid in full within sixty (60)
days after a written claim therefor by the indemnitee has been received by the
corporation, the indemnitee may file suit to recover the unpaid amount of such
claim and, if successful in whole or in part, shall be entitled to be paid the
expense of prosecuting such claim. In any such action the corporation shall have
the burden of proving that the indemnitee was not entitled to the requested
indemnification or advancement of expenses.

               Section 6.4. Non-Exclusivity of Rights. The rights conferred on
any person by this Article shall not be exclusive of any other rights which such
person may have or hereafter acquire under any statute, provision of the
certificate of incorporation, these bylaws, agreement, vote of stockholders or
disinterested directors or otherwise.

               Section 6.5. Other Indemnification. The corporation's obligation,
if any, to indemnify any person who was or is serving at its request as a
director, officer, employee or agent of another corporation, partnership, joint
venture, trust, enterprise or non-profit entity shall be reduced by any amount
such person may collect as indemnification from such other corporation,
partnership, joint venture, trust, enterprise or non-profit entity.

               Section 6.6. Amendment or Repeal. Any repeal or modification of
the foregoing provisions of this Article shall not adversely affect any right or
protection hereunder of any person in respect of any act or omission occurring
prior to the time of such repeal or modification.

                                  Miscellaneous

               Section 7.1. Fiscal Year. The fiscal year of the corporation
shall be determined by resolution of the Board of Directors.

               Section 7.2. Seal. The corporate seal shall be in such form as
may be approved from time to time by the Board of Directors.

               Section 7.3. Waiver of Notice of Meetings of Stockholders,
Directors and Committees. Any written waiver of notice, signed by the person
entitled to notice, whether before or after the time stated therein, shall be
deemed equivalent to notice. Attendance of a person at a meeting shall
constitute a waiver of notice of such meeting, except when the person attends a
meeting for the express purpose of objecting, at the beginning of the meeting,
to the transaction of any business because the meeting is not lawfully called or
convened. Neither the business to be transacted at, nor the purpose of any
regular or special meeting of the stockholders, directors, or members of a
committee of directors need be specified in any written waiver of notice.

               Section 7.4. Interested Directors; Quorum. No contract or
transaction between the corporation and one (1) or more of its directors or
officers, or between the corporation and any other corporation, partnership,
association, or other organization in which one (1) or more of its directors or
officers are directors or officers, or have a financial interest, shall be void
or voidable solely for this reason, or solely because the director or officer is
present at or participates in the meeting of the Board of Directors or committee
thereof which authorizes the contract or transaction, or solely because his or
their votes are counted for such purpose, if: (i) the material facts as to his
relationship or interest and as to the contract or transaction are disclosed or
are known to the Board of Directors or the committee, and the Board of Directors
or committee in good faith authorizes the contract or transaction by the
affirmative votes of a majority of the disinterested directors, even though the
disinterested directors be less than a quorum; or (ii) the material facts as to
his relationship or interest and as to the contract or transaction are disclosed
or are known to the stockholders entitled to vote thereon, and the contract or
transaction is specifically approved in good faith by vote of the stockholders;
or (iii) the contract or transaction is fair as to the corporation as of the
time it is authorized, approved or ratified, by the Board of Directors, a
committee thereof, or the stockholders. Common or interested directors may be
counted in determining the presence of a quorum at a meeting of the Board of
Directors or of a committee which authorizes the contract or transaction.

               Section 7.5. Form of Records. Any records maintained by the
corporation in the regular course of its business, including its stock ledger,
books of account, and minute books, may be kept on, or be in the form of, punch
cards, magnetic tape, photographs, microphotographs, or any other information
storage device, provided that the records so kept can be converted into clearly
legible form within a reasonable time.

bylaws and may alter and repeal any bylaws whether adopted by them or otherwise.

                COLUMBIA ELECTRIC PEDRICK GENERAL II CORPORATION


                                    ARTICLE I

                                  Stockholders

               Section 1.1. Annual Meetings. An annual meeting of stockholders
shall be held for the election of directors at such date, time and place, either
within or without the State of Delaware, as may be designated by resolution of
the Board of Directors from time to time. Any other proper business may be
transacted at the annual meeting.

               Section 1.2. Special Meetings. Special meetings of stockholders
for any purpose or purposes may be called at any time by the Board of Directors,
or by a committee of the Board of Directors that has been duly designated by the
Board of Directors and whose powers and authority, as expressly provided in a
resolution of the Board of Directors, include the power to call such meetings,
but such special meetings may not be called by any other person or persons.

               Section 1.3. Notice of Meetings. Whenever stockholders are
required or permitted to take any action at a meeting, a written notice of the
meeting shall be given that shall state the place, date and hour of the meeting
and, in the case of a special meeting, the purpose or purposes for which the
meeting is called. Unless otherwise provided by law, the certificate of
incorporation or these bylaws, the written notice of any meeting shall be given
not less than ten (10) nor more than sixty (60) days before the date of the
meeting to each stockholder entitled to vote at such meeting. If mailed, such
notice shall be deemed to be given when deposited in the United States mail,
postage prepaid, directed to the stockholder at his address as it appears on the
records of the corporation.

               Section 1.4. Adjournments. Any meeting of stockholders, annual or
special, may adjourn from time to time to reconvene at the same or some other
place, and notice need not be given of any such adjourned meeting if the time
and place thereof are announced at the meeting at which the adjournment is
taken. At the adjourned meeting the corporation may transact any business which
might have been transacted at the original meeting. If the adjournment is for
more than thirty (30) days, or if after the adjournment a new record date is
fixed for the adjourned meeting, notice of the adjourned meeting shall be given
to each stockholder of record entitled to vote at the meeting.

               Section 1.5. Quorum. Except as otherwise provided by law, the
certificate of incorporation or these bylaws, at each meeting of stockholders
the presence in person or by proxy of the holders of a majority in voting power
of the outstanding shares of stock entitled to vote at the meeting shall be
necessary and sufficient to constitute a quorum. In the absence of a quorum, the
stockholders so present may, by majority vote, adjourn the meeting from time to
time in the manner provided in Section 1.4 of these bylaws until a quorum shall
attend. Shares of its own stock belonging to the corporation or to another
corporation, if a majority of the shares entitled to vote in

                                                                     Exhibit 9-B
                                                                    Page 2 of 15


the election of directors of such other corporation is held, directly or
indirectly, by the corporation, shall neither be entitled to vote nor be counted
for quorum purposes; provided, however, that the foregoing shall not limit the
right of the corporation or any subsidiary of the corporation to vote stock,
including but not limited to its own stock, held by it in a fiduciary capacity.

               Section 1.6. Organization. Meetings of stockholders shall be
presided over by the Chairman of the Board, if any, or in his absence by the
Vice Chairman of the Board, if any, or in his absence by the President, or in
his absence by a Vice President, or in the absence of the foregoing persons by a
chairman designated by the Board of Directors, or in the absence of such
designation by a chairman chosen at the meeting. The Secretary shall act as
secretary of the meeting, but in his absence the person presiding over the
meeting may appoint any person to act as secretary of the meeting. The person
presiding over the meeting shall announce at the meeting of stockholders the
date and time of the opening and the closing of the polls for each matter upon
which the stockholders will vote.

               Section 1.7. Voting; Proxies. Except as otherwise provided by the
certificate of incorporation, each stockholder entitled to vote at any meeting
of stockholders shall be entitled to one (1) vote for each share of stock held
by him which has voting power upon the matter in question. Each stockholder
entitled to vote at a meeting of stockholders or to express consent or dissent
to corporate action in writing without a meeting may authorize another person or
persons to act for him by proxy, but no such proxy shall be voted or acted upon
after three (3) years from its date, unless the proxy provides for a longer
period. A proxy shall be irrevocable if it states that it is irrevocable and if,
and only as long as, it is coupled with an interest sufficient in law to support
an irrevocable power. A stockholder may revoke any proxy which is not
irrevocable by attending the meeting and voting in person or by filing with the
Secretary of the corporation an instrument in writing revoking the proxy or by
delivering a proxy in accordance with applicable law bearing a later date to the
Secretary of the corporation. Voting at meetings of stockholders need not be by
written ballot. At all meetings of stockholders for the election of directors a
plurality of the votes cast shall be sufficient to elect. All other elections
and questions shall, unless otherwise provided by law, the certificate of
incorporation or these bylaws, be decided by the affirmative vote of the holders
of a majority in voting power of the shares of stock which are present in person
or by proxy and entitled to vote thereon.

               Section 1.8. Fixing Date for Determination of Stockholders of
Record. In order that the corporation may determine the stockholders entitled to
notice of or to vote at any meeting of stockholders or any adjournment thereof,
or to express consent to corporate action in writing without a meeting, or
entitled to receive payment of any dividend or other distribution or allotment
of any rights, or entitled to exercise any rights in respect of any change,
conversion or exchange of stock or for the purpose of any other lawful action,
the Board of Directors may fix a record date, which record date shall not
precede the date upon which the resolution fixing the record date is adopted by
the Board of Directors, and which record date: (i) in the case of determination
of stockholders entitled to vote at any meeting of stockholders or adjournment
thereof, shall, unless otherwise required by law, not be more than sixty (60)
nor less than ten (10) days before the date of such meeting; (ii) in the case of
determination of stockholders entitled to express consent to corporate action in
writing without a meeting, shall not be more than ten (10) days from the date
<PAGE>   238
                                                                     Exhibit 9-B
                                                                    Page 3 of 15


upon which the resolution fixing the record date is adopted by the Board of
Directors; and (iii) in the case of determination of stockholders for the
purpose of any other lawful action, shall not be more than sixty (60) days prior
to such other action. If no record date is fixed: (iv) the record date for
determining stockholders entitled to notice of or to vote at a meeting of
stockholders shall be at the close of business on the day next preceding the day
on which notice is given, or, if notice is waived, at the close of business on
the day next preceding the day on which the meeting is held; (v) the record date
for determining stockholders entitled to express consent to corporate action in
writing without a meeting, when no prior action of the Board of Directors is
required by law, shall be the first date on which a signed written consent
setting forth the action taken or proposed to be taken is delivered to the
corporation in accordance with applicable law, or, if prior action by the Board
of Directors is required by law, shall be at the close of business on the day on
which the Board of Directors adopts the resolution taking such prior action; and
(vi) the record date for determining stockholders for the purpose of any other
lawful action, shall be at the close of business on the day on which the Board
of Directors adopts the resolution relating thereto. A determination of
stockholders of record entitled to notice of or to vote at a meeting of
stockholders shall apply to any adjournment of the meeting; provided, however,
that the Board of Directors may fix a new record date for the adjourned meeting.

               Section 1.9. List of Stockholders Entitled to Vote. The Secretary
shall prepare and make, at least ten (10) days before every meeting of
stockholders, a complete list of the stockholders entitled to vote at the
meeting, arranged in alphabetical order, and showing the address of each
stockholder and the number of shares registered in the name of each stockholder.
Such list shall be open to the examination of any stockholder, for any purpose
germane to the meeting, during ordinary business hours, for a period of at least
ten (10) days prior to the meeting, either at a place within the city where the
meeting is to be held, which place shall be specified in the notice of the
meeting, or, if not so specified, at the place where the meeting is to be held.
The list shall also be produced and kept at the time and place of the meeting
during the whole time thereof and may be inspected by any stockholder who is
present. Upon the willful neglect or refusal of the directors to produce such a
list at any meeting for the election of directors, they shall be ineligible for
election to any office at such meeting. Except as otherwise provided by law, the
stock ledger shall be the only evidence as to who are the stockholders entitled
(i) to examine the stock ledger, the list of stockholders entitled to vote at
the meeting or the books of the corporation, (ii) to vote in person or by proxy
at any meeting of stockholders, or (iii) to express consent or dissent to
corporate action in writing without a meeting.

               Section 1.10. Action By Consent of Stockholders. Unless otherwise
restricted by the certificate of incorporation, any action required or permitted
to be taken at any annual or special meeting of the stockholders may be taken
without a meeting, without prior notice and without a vote, if a consent or
consents in writing, setting forth the action so taken, shall be signed by the
holders of outstanding stock having not less than the minimum number of votes
that would be necessary to authorize or take such action at a meeting at which
all shares entitled to vote thereon were present and voted and shall be
delivered (by hand or by certified or registered mail, return receipt requested)
to the corporation by delivery to its registered office in the State of
Delaware, its principal place of business, or an officer or agent of the
corporation having custody of the book in which minutes of proceedings of
meetings of stockholders are recorded. Prompt notice of the

                                                                    Page 4 of 15


taking of the corporate action without a meeting by less than unanimous written
consent shall be given to those stockholders who have not consented in writing.

               Section 1.11. Inspectors of Election. The corporation may, and
shall if required by law, in advance of any meeting of stockholders, appoint one
(1) or more inspectors of election, who may be employees of the corporation, to
act at the meeting or any adjournment thereof and to make a written report
thereof. The corporation may designate one (1) or more persons as alternate
inspectors to replace any inspector who fails to act. In the event that no
inspector so appointed or designated is able to act at a meeting of the
stockholders, the person presiding at the meeting shall appoint one (1) or more
inspectors to act at the meeting. Each inspector, before entering upon the
discharge of his or her duties, shall take and sign an oath to execute
faithfully the duties of inspector with strict impartiality and according to the
best of his or her ability. The inspector or inspectors so appointed or
designated shall (i) ascertain the number of shares of capital stock of the
corporation outstanding and the voting power of each such share, (ii) determine
the shares of capital stock of the corporation represented at the meeting and
the validity of proxies and ballots, (iii) count all votes and ballots, (iv)
determine and retain for a reasonable period a record of the disposition of any
challenges made to any determination by the inspectors, and (v) certify their
determination of the number of shares of capital stock of the corporation
represented at the meeting and such inspector's or inspectors' count of all
votes and ballots. Such certification and report shall specify such other
information as may be required by law. In determining validity and counting of
proxies and ballots cast at any meeting of stockholders of the corporation, the
inspectors may consider such information as is permitted by applicable law. No
person who is a candidate for an office at an election may serve as an inspector
at such election.

               Section 1.12. Conduct of Meetings. The Board of Directors of the
corporation may adopt by resolution such rules and regulations for the conduct
of the meeting of stockholders as it shall deem appropriate. Except to the
extent inconsistent with such rules and regulations as adopted by the Board of
Directors, the person presiding over any meeting of stockholders shall have the
right and authority to prescribe such rules, regulations and procedures and to
do all such acts as, in the judgment of such person, are appropriate for the
proper conduct of the meeting. Such rules, regulations or procedures, whether
adopted by the Board of Directors or prescribed by the person presiding over the
meeting, may include, without limitation, the following: (i) the establishment
of an agenda or order of business for the meeting; (ii) rules and procedures for
maintaining order at the meeting and the safety of those present; (iii)
limitations on attendance at or participation in the meeting to stockholders of
record of the corporation, their duly authorized and constituted proxies or such
other persons as the person presiding over the meeting shall determine; (iv)
restrictions on entry to the meeting after the time fixed for the commencement
thereof; and (v) limitations on the time allotted to questions or comments by
participants. Unless and to the extent determined by the Board of Directors or
the person presiding over the meeting, meetings of stockholders shall not be
required to be held in accordance with the rules of parliamentary procedure.

                               Board of Directors

               Section 2.1. Number; Qualifications. The Board of Directors shall
consist of one (1) or more members. The number of members comprising the Board
of Directors initially shall be the number of persons named as directors in the
certificate of incorporation (or if no person is so named, the number of persons
elected by the Incorporator). The number of members comprising the Board of
Directors thereafter shall be determined from time to time by resolution of the
Board of Directors. Directors need not be stockholders.

               Section 2.2. Election; Resignation; Removal; Vacancies. The Board
of Directors initially shall consist of the person or persons named as Directors
in the certificate of incorporation (or, if no person is so named, the person or
persons elected by the Incorporator), and each director so elected shall hold
office until his successor is elected and qualified or until his earlier death,
resignation, or removal. At the first annual meeting of stockholders and at each
annual meeting thereafter, the stockholders shall elect directors each of whom
shall hold office until his successor is elected and qualified or until his
earlier death, resignation, or removal. Any director may resign at any time upon
written notice to the corporation. Any newly created directorship or any vacancy
occurring in the Board of Directors for any cause may be filled by a majority of
the remaining members of the Board of Directors, although such majority is less
than a quorum, or by a plurality of the votes cast at a meeting of stockholders,
and each director so elected shall hold office until the expiration of the term
of office of the director whom he has replaced, or until his successor is
elected and qualified, or until his earlier death, resignation, or removal.

               Section 2.3. Regular Meetings. Regular meetings of the Board of
Directors may be held at such places within or without the State of Delaware and
at such times as the Board of Directors may from time to time determine, and if
so determined notices thereof need not be given.

Board of Directors shall be given by the person or persons calling the meeting
at least twenty-four (24) hours before the special meeting.

               Section 2.5. Telephonic Meetings Permitted. Members of the Board
of Directors, or any committee designated by the Board of Directors, may
participate in a meeting thereof by means of conference telephone or similar
communications equipment by means of which all persons participating in the
meeting can hear each other, and participation in a meeting pursuant to this
bylaw shall constitute presence in person at such meeting.

               Section 2.6. Quorum; Vote Required for Action. At all meetings of
the Board of Directors a majority of the whole Board of Directors shall
constitute a quorum for the transaction of business. Except in cases in which
the certificate of incorporation, these bylaws or applicable law

otherwise provides, the vote of a majority of the directors present at a meeting
at which a quorum is present shall be the act of the Board of Directors.

               Section 2.7. Organization. Meetings of the Board of Directors
shall be presided over by the Chairman of the Board, if any, or in his absence
by the Vice Chairman of the Board, if any, or in his absence by the President,

The Secretary shall act as secretary of the meeting, but in his absence the
person presiding over the meeting may appoint any person to act as secretary of
the meeting.

               Section 2.8. Informal Action by Directors. Unless otherwise
restricted by the certificate of incorporation or these bylaws, any action
required or permitted to be taken at any meeting of the Board of Directors, or
of any committee thereof, may be taken without a meeting if all members of the
Board of Directors or such committee, as the case may be, consent thereto in
writing, and the writing or writings are filed with the minutes of proceedings
of the Board of Directors or committee.

                                   ARTICLE III

                                   Committees

               Section 3.1. Committees. The Board of Directors may, by
resolution passed by a majority of the whole Board of Directors, designate one
(1) or more committees, each committee to consist of one (1) or more of the
directors of the corporation. The Board of Directors may designate one (1) or
more directors as alternate members of any committee, who may replace any absent
or disqualified member at any meeting of the committee. In the absence or
disqualification of a member of the committee, the member or members thereof
present at any meeting and not disqualified from voting, whether or not he or
they constitute a quorum, may unanimously appoint another member of the Board of
Directors to act at the meeting in place of any such absent or disqualified
member. Any such committee, to the extent permitted by law and to the extent
provided in the resolution of the Board of Directors, shall have and may
exercise all the powers and authority of the Board of Directors in the
management of the business and affairs of the corporation, and may authorize the
seal of the corporation to be affixed to all papers which may require it.

               Section 3.2. Committee Rules. Unless the Board of Directors
otherwise provides, each committee designated by the Board of Directors may
make, alter and repeal rules for the conduct of its business. In the absence of
such rules each committee shall conduct its business in the same manner as the
Board of Directors conducts its business pursuant to Article II of these bylaws.

                                   ARTICLE IV

                                    Officers

               Section 4.1. Executive Officers; Election; Qualifications; Term

members. The Board of Directors may also choose one (1) or more Vice Presidents,
one (1) or more Assistant Secretaries, a Treasurer and one (1) or more Assistant
Treasurers. Each such officer shall hold office until the first meeting of the
Board of Directors after the annual meeting of stockholders next succeeding his
election, and until his successor is elected and qualified or until his earlier
death, resignation, or removal. Any officer may resign at any time upon written
notice to the corporation. The Board of Directors may remove any officer with or
without cause at any time, but such removal shall be without prejudice to the
contractual rights of such officer, if any, with the corporation. Any number of
offices may be held by the same person. Any vacancy occurring in any office of
the corporation by death, resignation, removal, or otherwise may be filled for
the unexpired portion of the term by the Board of Directors at any regular or
special meeting.

               Section 4.2.  Powers and Duties of Executive Officers.

               (i) President. The President shall be the chief executive officer
of the corporation. Subject to the provisions of the certificate of
incorporation, these bylaws, and the direction of the Board of Directors, the
President shall have the responsibility for the general management and control

Secretary, if any, and each Assistant Treasurer, if any, shall have such powers
and perform such duties as the Board of Directors may from time to time
prescribe.

               (vi) Delegation of Authority. The Board of Directors may from

                                    ARTICLE V

                                      Stock

entitled to have a certificate signed by or in the name of the corporation by
the Chairman or Vice Chairman of the Board of Directors, if any, or the
President or a Vice President, and by the Treasurer or an Assistant Treasurer,
or the Secretary or an Assistant Secretary, of the corporation certifying the
number of shares owned by him in the corporation. Any of or all the signatures
on the certificate may be a facsimile. In case any officer, transfer agent, or
registrar who has signed or whose facsimile signature has been placed upon a
certificate shall have ceased to be such officer, transfer agent, or registrar
before such certificate is issued, it may be issued by the corporation with the
same effect as if he were such officer, transfer agent, or registrar at the date
of issue.

               Section 5.2. Lost, Stolen or Destroyed Stock Certificates;
Issuance of New Certificates. The corporation may issue a new certificate of
stock in the place of any certificate theretofore issued by it, alleged to have
been lost, stolen or destroyed, and the corporation may require the owner of the
lost, stolen or destroyed certificate, or his legal representative, to give the
corporation a bond sufficient to indemnify it against any claim that may be made
against it on account of the alleged loss, theft or destruction of any such
certificate or the issuance of such new certificate.

                                   ARTICLE VI

                                 Indemnification

               Section 6.1. Right to Indemnification. The corporation shall
indemnify and hold harmless, to the fullest extent permitted by applicable law
as it presently exists or may hereafter be amended, any person who was or is
made or is threatened to be made a party or is otherwise involved in any
threatened, pending, or completed action, suit or proceeding, whether civil,
criminal, administrative or investigative (a "proceeding") by reason of the fact
that he, or a person for whom he is the legal representative, is or was a
director or officer of the corporation or is or was serving at the request of
the corporation as a director, officer, employee or agent of another corporation
or of a partnership, joint venture, trust, other enterprise or non-profit
entity, including service with respect to employee benefit plans (an
"indemnitee"), against all liability and loss suffered and expenses (including
attorneys' fees) reasonably incurred by such indemnitee. The corporation shall
be required to indemnify an indemnitee in connection with a proceeding (or part

                                                                     Exhibit 9-B

thereof) initiated by such indemnitee only if the initiation of such proceeding
(or part thereof) by the indemnitee was authorized by the Board of Directors of
the corporation.

               Section 6.2. Advancement of Expenses. The corporation shall pay
the expenses (including attorneys' fees) incurred by an indemnitee in defending
any proceeding referred to in Section 6.1 in advance of its final disposition;
provided, however, that the payment of expenses incurred by an indemnitee in
advance of the final disposition of such proceeding shall be made only upon
receipt of an undertaking by the indemnitee to repay all amounts advanced if it
should ultimately be determined that the indemnitee is not entitled to be
indemnified under this Article or otherwise.

               Section 6.3. Claims. If a claim for indemnification or
advancement of expenses under this Article is not paid in full within sixty (60)
days after a written claim therefor by the indemnitee has been received by the
corporation, the indemnitee may file suit to recover the unpaid amount of such
claim and, if successful in whole or in part, shall be entitled to be paid the
expense of prosecuting such claim. In any such action the corporation shall have
the burden of proving that the indemnitee was not entitled to the requested
indemnification or advancement of expenses.

               Section 6.4. Non-Exclusivity of Rights. The rights conferred on
any person by this Article shall not be exclusive of any other rights which such
person may have or hereafter acquire under any statute, provision of the
certificate of incorporation, these bylaws, agreement, vote of stockholders or
disinterested directors or otherwise.

               Section 6.5. Other Indemnification. The corporation's obligation,
if any, to indemnify any person who was or is serving at its request as a
director, officer, employee or agent of another corporation, partnership, joint
venture, trust, enterprise or non-profit entity shall be reduced by any amount
such person may collect as indemnification from such other corporation,
partnership, joint venture, trust, enterprise or non-profit entity.

               Section 6.6. Amendment or Repeal. Any repeal or modification of
the foregoing provisions of this Article shall not adversely affect any right or
protection hereunder of any person in respect of any act or omission occurring
prior to the time of such repeal or modification.

                                   ARTICLE VII

                                  Miscellaneous

shall be determined by resolution of the Board of Directors.

               Section 7.2. Seal. The corporate seal shall be in such form as
may be approved from time to time by the Board of Directors.

               Section 7.3. Waiver of Notice of Meetings of Stockholders,
Directors and Committees. Any written waiver of notice, signed by the person
entitled to notice, whether before or after the

                                                                     Exhibit 9-B

time stated therein, shall be deemed equivalent to notice. Attendance of a
person at a meeting shall constitute a waiver of notice of such meeting, except
when the person attends a meeting for the express purpose of objecting, at the
beginning of the meeting, to the transaction of any business because the meeting
is not lawfully called or convened. Neither the business to be transacted at,
nor the purpose of any regular or special meeting of the stockholders,
directors, or members of a committee of directors need be specified in any
written waiver of notice.

               Section 7.4. Interested Directors; Quorum. No contract or
transaction between the corporation and one (1) or more of its directors or
officers, or between the corporation and any other corporation, partnership,
association, or other organization in which one (1) or more of its directors or
officers are directors or officers, or have a financial interest, shall be void
or voidable solely for this reason, or solely because the director or officer is
present at or participates in the meeting of the Board of Directors or committee
thereof which authorizes the contract or transaction, or solely because his or
their votes are counted for such purpose, if: (i) the material facts as to his
relationship or interest and as to the contract or transaction are disclosed or
are known to the Board of Directors or the committee, and the Board of Directors
or committee in good faith authorizes the contract or transaction by the
affirmative votes of a majority of the disinterested directors, even though the
disinterested directors be less than a quorum; or (ii) the material facts as to
his relationship or interest and as to the contract or transaction are disclosed
or are known to the stockholders entitled to vote thereon, and the contract or
transaction is specifically approved in good faith by vote of the stockholders;
or (iii) the contract or transaction is fair as to the corporation as of the
time it is authorized, approved or ratified, by the Board of Directors, a
committee thereof, or the stockholders. Common or interested directors may be
counted in determining the presence of a quorum at a meeting of the Board of
Directors or of a committee which authorizes the contract or transaction.

               Section 7.5. Form of Records. Any records maintained by the
corporation in the regular course of its business, including its stock ledger,
books of account, and minute books, may be kept on, or be in the form of, punch
cards, magnetic tape, photographs, microphotographs, or any other information
storage device, provided that the records so kept can be converted into clearly
legible form within a reasonable time.

               Section 7.6. Amendment of Bylaws. These bylaws may be altered or
repealed, and new bylaws made, by the Board of Directors to the extent permitted
by the certificate of incorporation, but the stockholders may make additional
bylaws and may alter and repeal any bylaws whether adopted by them or otherwise.

owner of such lost, stolen or destroyed certificate or certificates, or his
legal representative, to advertise the same in such manner as it shall require
and/or to give the Corporation a bond in such sum as it may direct as indemnity
against any claim that may be made against the Corporation with respect to the
certificate alleged to have been lost, stolen or destroyed.

                                  ARTICLE VIII
                                 INDEMNIFICATION

         (a) Right to Indemnification. The Corporation shall to the fullest
extent permitted by applicable law as then in effect indemnify any person (the
"Indemnitee") who was or is involved in any manner (including, without
limitation, as a party or a witness) or is threatened to be made so involved in
any threatened, pending or completed investigation, claim, action, suit or
proceeding, whether civil, criminal, administrative, or investigative (including
without limitation, any action, suit, or proceeding by or in the right of the
Corporation to procure a judgment in its favor) (a "Proceeding") by reason of
the fact that such person is or was a director, officer, employee, or agent of
the Corporation, or is or was serving at the request of the Corporation as a
director, officer, employee, or agent of another Corporation, partnership, joint
venture, trust, or other enterprise (including, without limitation, any employee
benefit plan) against all expenses (including attorneys' fees), judgments,
fines, and amounts paid in settlement actually and reasonably incurred by such
person in connection with such Proceeding. Such indemnification shall be a
contract right and shall include the right to receive payment of any expenses
incurred by the Indemnitee in connection with such Proceeding in advance of its
final disposition, consistent with the provisions of applicable law as then in
effect.

         (b) Insurance, Contracts, and Funding. The Corporation may purchase and
maintain insurance to protect itself and any indemnitee against any expenses,
judgments, fines, and amounts paid in settlement as specified in Section (a) of
this Article VIII or incurred by an Indemnitee in connection with any proceeding
referred to in Section (a) of this Article VIII, to
<PAGE>   261
                                                                    Exhibit 10-B
                                                                   Page 11 of 14


the fullest extent permitted by applicable law as then in effect. The
Corporation may enter into contracts with any director, officer, employee, or
agent of the Corporation or use other means in furtherance of the provisions of
this Article VIII to ensure the payment of such amounts as may be necessary to
effect indemnification as provided in this Article VIII.

         (c) Indemnification; Not Exclusive Right. The right of indemnification
provided in this Article VIII shall not be exclusive of any other rights to
which those seeking indemnification may otherwise be entitled, and the
provisions of this Article VIII shall inure to the benefit of the heirs and
legal representatives of any person entitled to indemnity under this Article
VIII and shall be applicable to Proceedings commenced or continuing after the
adoption of this Article VIII, whether arising from acts or omissions occurring
before or after such adoption.

         (d) Advancement of Expenses; Procedures; Presumptions and Effect of
Certain Proceedings; Remedies. In furtherance but not in limitation of the
foregoing provisions, the following procedures, presumptions, and remedies shall
apply with respect to advancement of expenses and the right to indemnification
under this Article VIII:

         (1) Advance of Expenses. All reasonable expenses incurred by or on
behalf of the Indemnitee in connection with any Proceeding shall be advanced to
the Indemnitee by the Corporation within 20 days after the receipt by the
Corporation of a statement or statements from the Indemnitee requesting such
advance or advances from time to time, whether prior to or after final
disposition of such Proceeding. Such statement or statements shall reasonably
evidence the expenses incurred by the Indemnitee and, if required by law at the
time of such advance, shall include or be accompanied by an undertaking by or on
behalf of the Indemnitee to repay the amounts advanced if it should ultimately
be determined that the Indemnitee is not entitled to be indemnified against such
expenses pursuant to this Article VIII.

         (2) Procedure for Determination of Entitlement to Indemnification.
         (i) To obtain indemnification under this Article VIII, an Indemnitee
shall submit to the Secretary of the Corporation a written request, including
such documentation and information as is reasonably available to the Indemnitee
and reasonably necessary to determine whether and to what extent the Indemnitee
is entitled to indemnification (the "Supporting Documentation"). The
determination of the Indemnitee's entitlement to indemnification shall be made
not later than 60 days after receipt by the Corporation of the written request
for indemnification together with Supporting Documentation. The Secretary of the
Corporation shall advise the Board of Directors in writing, promptly upon
receipt of such a request for indemnification, that the Indemnitee has requested
indemnification.

         (ii) The Indemnitee's entitlement to indemnification under this Article
VIII shall be determined in one of the following ways: (A) by a majority vote of
the Disinterested Directors (as hereinafter defined), even if they constitute
less than a quorum of the Board of Directors; (B) by a written opinion of
Independent Counsel (as hereinafter defined) if (x) a Change of Control (as
hereinafter defined) shall have occurred and the Indemnitee so requests or (y) a
quorum of the Board of Directors consisting of Disinterested Directors is not
obtainable or, even if obtainable, a majority of such Disinterested Directors so
directs; (C) by the stockholders of the Corporation (but only if a majority of
the Disinterested Directors present the issue of entitlement to indemnification
to the stockholders for their determination); or (D) as provided in Section
(d)(3).
<PAGE>   262
                                                                    Exhibit 10-B
                                                                   Page 12 of 14

         (iii) In the event the determination of entitlement to indemnification
is to be made by Independent Counsel pursuant to Section (d)(2)(ii), a majority
of the Board of Directors shall select the Independent Counsel, but only an
Independent Counsel to which the Indemnitee does not reasonably object;
provided, however, that if a Change of Control shall have occurred, the
Indemnitee shall select such Independent Counsel, but only an Independent
Counsel to which the Board of Directors does not reasonably object.

         (iv) The only basis upon which a finding of no entitlement to
indemnification may be made is that indemnification is prohibited by law.

         (3) Presumptions and Effect of Certain Proceedings. Except as otherwise
expressly provided in this Article VIII, if a Change of Control shall have
occurred, the Indemnitee shall be presumed to be entitled to indemnification
under this Article VIII upon submission of a request for indemnification
together with the Supporting Documentation in accordance with Section (d)(2)(i),
and thereafter the Corporation shall have the burden of proof to overcome that
presumption in reaching a contrary determination. In any event, if the person or
persons empowered under Section (d)(2) to determine entitlement to
indemnification shall not have been appointed or shall not have made a
determination within 60 days after receipt by the Corporation of the request
therefor together with the Supporting Documentation, the Indemnitee shall be
deemed to be entitled to indemnification, and the Indemnitee shall be entitled
to such indemnification unless (A) the Indemnitee misrepresented or failed to
disclose a material fact in making the request for indemnification or in the
Supporting Documentation or (B) such indemnification is prohibited by law. The
termination of any Proceeding described in Section (a), or of any claim, issue,
or matter therein, by judgment, order, settlement, or conviction, or upon a plea
of nolo contendere or its equivalent, shall not of itself adversely affect the
right of the Indemnitee to indemnification or create a presumption that the
Indemnitee did not act in good faith and in a manner which the Indemnitee
reasonably believed to be in or not opposed to the best interests of the
Corporation or, with respect to any criminal Proceeding, that the Indemnitee had
reasonable cause to believe that the Indemnitee's conduct was unlawful.

         (4) Remedies of Indemnitee.
         (i) In the event that a determination is made pursuant to Section
(d)(2) or (3) that the Indemnitee is not entitled to indemnification under this
Article VIII, (A) the Indemnitee shall be entitled to seek an adjudication of
his entitlement to such indemnification either, at the Indemnitee's sole option,
in (x) an appropriate court of the State of Delaware or any other court of
competent jurisdiction, or (y) an arbitration to be conducted by a single
arbitrator pursuant to the rules of the American Arbitration Association; (B)
any such judicial proceeding or arbitration shall be de novo and the Indemnitee
shall not be prejudiced by reason of such adverse determination; and (C) in any
such judicial proceeding or arbitration, the Corporation shall have the burden
of proving that the Indemnitee is not entitled to indemnification under this
Article VIII.

         (ii) If pursuant to Section (d)(2) or (3) a determination shall have
been made or deemed to have been made that the Indemnitee is entitled to
indemnification, the Corporation shall be obligated to pay the amounts
constituting such indemnification within five days after such determination has
been made or is deemed to have been made and shall be conclusively
<PAGE>   263
                                                                    Exhibit 10-B
                                                                   Page 13 of 14


bound by such determination unless (A) the Indemnitee misrepresented or failed
to disclose a material fact in making the request for indemnification or in the
Supporting Documentation, or (B) such indemnification is prohibited by law. In
the event that (X) advancement of expenses is not timely made pursuant to
Section (d)(l), or (Y) payment of indemnification is not made within five days
after a determination of entitlement to indemnification has been made or deemed
to have been made pursuant to Section (d)(2) or (3), the Indemnitee shall be
entitled to seek judicial enforcement of the Corporation's obligation to pay to
the Indemnitee such advancement of expenses or indemnification. Notwithstanding
the foregoing, the Corporation may bring an action in an appropriate court in
the State of Delaware or any other court of competent jurisdiction, contesting
the right of the Indemnitee to receive indemnification hereunder due to the
occurrence of an event described in subclause (A) or (B) of this clause (ii) (a
"Disqualifying Event"); provided, however, that in any such action the
Corporation shall have the burden of proving the occurrence of such
Disqualifying Event.

         (iii) The Corporation shall be precluded from asserting in any judicial
proceeding or arbitration commenced pursuant to this Section (d)(4) that the
procedures and presumptions of this Article VIII are not valid, binding, and
enforceable and shall stipulate in any such court or before any such arbitrator
that the Corporation is bound by all the provisions of this Article VIII.

         (iv) In the event that pursuant to this Section (d)(4) the Indemnitee
seeks a judicial adjudication of or an award in arbitration to enforce his
rights under, or to recover damages for breach of this Article VIII, the
Indemnitee shall be entitled to recover from the Corporation, and shall be
indemnified by the Corporation against, any expenses actually and reasonably
incurred by the Indemnitee if the Indemnitee prevails in such judicial
adjudication or arbitration. If it shall be determined in such judicial
adjudication or arbitration that the Indemnitee is entitled to receive part but
not all of the indemnification or advancement of expenses sought, the expenses
incurred by the Indemnitee in connection with such judicial adjudication or
arbitration shall be prorated accordingly.

         (5) Definitions. For purposes of this Section (d):
         (i) "Change in Control" means (A) so long as the Public Utility Holding
Company Act of 1935 is in effect, any "company" becoming a "holding company" in
respect to the Corporation or any determination by the Securities and Exchange
Commission that any "person" should be subject to the obligations, duties, and
liabilities if imposed by said Act by virtue or his, hers or its influence over
the management or policies of the Corporation, or (B) whether or not said Act is
in effect, a change in control of the Corporation of a nature that would be
required to be reported in response to Item 6(e) of Schedule 14A of Regulation
14A promulgated under the Securities Exchange Act of 1934 (the "Act"), whether
or not the Corporation is then subject to such reporting requirement; provided
that, without limitation, such a change in control shall be deemed to have
occurred if (i) any "person" (as such term is used in Section 13(d) and 14(d) of
the Act) is or becomes the "beneficial owner" (as defined in Rule 13d-3 under
the Act), directly or indirectly, of securities of the Corporation representing
10 percent or more of the combined voting power of the Corporation's then
outstanding securities without the prior approval of at least two-thirds of the
members of the Board of Directors in office immediately prior to such
acquisition; (ii) the Corporation is a party to a merger, consolidation, sale of
assets or other reorganization, or a proxy contest, as a consequence of which
members of the Board of Directors in office immediately prior to such
transaction or event constitute less than a majority of the
<PAGE>   264
                                                                    Exhibit 10-B
                                                                   Page 14 of 14


Board of Directors thereafter; or (iii) during any period of two consecutive
years, individuals who at the beginning of such period constituted the Board of
Directors (including for this purpose any new director whose election or
nomination for election by the Corporation's stockholders was approved by a vote
of at least two-thirds of the directors then still in office who were directors
at the beginning of such period) cease for any reason to constitute at least a
majority of the Board of Directors.

         (ii) "Disinterested Director" means a director of the Corporation who
is not or was not a party to the Proceeding in respect of which indemnification
is sought by the Indemnitee.

         (iii) "Independent Counsel" means a law firm or a member of a law firm
that neither presently is, nor in the past five years has been, retained to
represent: (A) the Corporation or the Indemnitee in any matter material to
either such party, or (B) any other party to the Proceeding giving rise to a
claim for indemnification under this Article VIII. Notwithstanding the
foregoing, the term "Independent Counsel" shall not include any person who,
under the applicable standards of professional conduct then prevailing under the
law of the State of Delaware, would have a conflict of interest in representing
either the Corporation or the Indemnitee in an action to determine the
Indemnitee's rights under this Article VIII.

         (e) Severability. If any provision or provisions of this Article VIII
shall be held to be invalid, illegal or unenforceable for any reason whatsoever:
(i) the validity, legality, and enforceability of the remaining provisions of
this Article VIII (including, without limitation, all portions of any paragraph
of this Article VIII containing any such provision held to be invalid, illegal,
or unenforceable, that are not themselves invalid, illegal, or unenforceable)
shall not in any way be affected or impaired thereby; and (ii) to the fullest
extent possible, the provisions of this Article VIII (including, without
limitation, all portions of any paragraph of this Article VIII containing any
such provision held to be invalid, illegal, or unenforceable that are not
themselves invalid, illegal, or unenforceable) shall be construed so as to give
effect to the intent manifested by the provision held invalid, illegal, or
unenforceable.

         (f) Successor Laws, Regulations, and Agencies. Reference herein to
laws, regulations, or agencies shall be deemed to include all amendments
thereof, substitutions therefor, and successors thereto.

                                   ARTICLE IX
                                   AMENDMENTS

         Section 1. These Bylaws may be altered, amended, or repealed or new
Bylaws may be adopted by the stockholders or by the Board of Directors, when
such power is conferred upon the Board of Directors by the Certificate of
Incorporation, at any regular meeting of the stockholders or of the Board of
Directors or at any special meeting of the stockholders or of the Board of
Directors if notice of such alteration, amendment, repeal, or adoption of new
Bylaws be contained in the notice of such special meeting.

subject to the provisions of the Certificate of Incorporation.

         Section 2. Before payment of any dividend, there may be set aside out
of any funds of the Corporation available for dividends such sum or sums as the
directors from time to time, in their absolute discretion, think proper as a
reserve or reserves to meet contingencies, or for equalizing dividends, or for
repairing or maintaining any property of the Corporation, or for such other
purpose as the directors shall think conducive to the interest of the

instructions for the payment of money, which may, with respect to routine items,
include instructions as to the amount to be transferred, to any bank, pursuant

                                 INDEMNIFICATION
         (a) Right to Indemnification. The Corporation shall to the fullest
extent permitted by applicable law as then in effect indemnify any person (the
"Indemnitee") who was or is involved in any manner (including, without
limitation, as a party or a witness) or is threatened to be made so involved in
any threatened, pending or completed investigation, claim, action, suit or
proceeding, whether civil, criminal, administrative, or investigative (including
without limitation, any action, suit, or proceeding by or in the right of the
Corporation to procure a judgment in its favor) (a "Proceeding") by reason of
the fact that such person is or was a director, officer, employee, or agent of
the Corporation, or is or was serving at the request of the Corporation as a
director, officer, employee, or agent of another Corporation, partnership, joint
venture, trust, or other enterprise (including, without limitation, any employee
benefit plan) against all expenses (including attorneys' fees), judgments,
fines, and amounts paid in settlement actually and reasonably incurred by such
person in connection with such Proceeding. Such indemnification shall be a
contract right and shall include the right to receive payment of any expenses
incurred by the Indemnitee in connection with such Proceeding in advance of its
final disposition, consistent with the provisions of applicable law as then in
effect.

         (b) Insurance, Contracts, and Funding. The Corporation may purchase and
maintain insurance to protect itself and any indemnitee against any expenses,
judgments, fines, and amounts paid in settlement as specified in Section (a) of
this Article VIII or incurred by an Indemnitee in connection with any proceeding
referred to in Section (a) of this Article VIII, to the fullest extent permitted
by applicable law as then in effect. The Corporation may enter into contracts
with any director, officer, employee, or agent of the Corporation or use other
means in furtherance of the provisions of this Article VIII to ensure the
payment of such amounts as may be necessary to effect indemnification as
provided in this Article VIII.

         (c) Indemnification; Not Exclusive Right. The right of indemnification
provided in this Article VIII shall not be exclusive of any other rights to
which those seeking indemnification may otherwise be entitled, and the
provisions of this Article VIII shall inure to the benefit of the heirs and
legal representatives of any person entitled to indemnity under this Article
VIII and shall be applicable to Proceedings commenced or continuing after the
adoption of this Article VIII, whether arising from acts or omissions occurring
before or after such adoption.

         (d) Advancement of Expenses; Procedures; Presumptions and Effect of
Certain Proceedings; Remedies. In furtherance but not in limitation of the
foregoing provisions, the

                                                                    Exhibit 13-B
                                                                   Page 11 of 14


following procedures, presumptions, and remedies shall apply with respect to
advancement of expenses and the right to indemnification under this Article
VIII:

         (1) Advance of Expenses. All reasonable expenses incurred by or on
behalf of the Indemnitee in connection with any Proceeding shall be advanced to
the Indemnitee by the Corporation within 20 days after the receipt by the
Corporation of a statement or statements from the Indemnitee requesting such
advance or advances from time to time, whether prior to or after final
disposition of such Proceeding. Such statement or statements shall reasonably
evidence the expenses incurred by the Indemnitee and, if required by law at the
time of such advance, shall include or be accompanied by an undertaking by or on
behalf of the Indemnitee to repay the amounts advanced if it should ultimately
be determined that the Indemnitee is not entitled to be indemnified against such
expenses pursuant to this Article VIII.

         (2) Procedure for Determination of Entitlement to Indemnification.
         (i) To obtain indemnification under this Article VIII, an Indemnitee
shall submit to the Secretary of the Corporation a written request, including
such documentation and information as is reasonably available to the Indemnitee
and reasonably necessary to determine whether and to what extent the Indemnitee
is entitled to indemnification (the "Supporting Documentation"). The
determination of the Indemnitee's entitlement to indemnification shall be made
not later than 60 days after receipt by the Corporation of the written request
for indemnification together with Supporting Documentation. The Secretary of the
Corporation shall advise the Board of Directors in writing, promptly upon
receipt of such a request for indemnification, that the Indemnitee has requested
indemnification.

         (ii) The Indemnitee's entitlement to indemnification under this Article
VIII shall be determined in one of the following ways: (A) by a majority vote of
the Disinterested Directors (as hereinafter defined), even if they constitute
less than a quorum of the Board of Directors; (B) by a written opinion of
Independent Counsel (as hereinafter defined) if (x) a Change of Control (as
hereinafter defined) shall have occurred and the Indemnitee so requests or (y) a
quorum of the Board of Directors consisting of Disinterested Directors is not
obtainable or, even if obtainable, a majority of such Disinterested Directors so
directs; (C) by the stockholders of the Corporation (but only if a majority of
the Disinterested Directors present the issue of entitlement to indemnification
to the stockholders for their determination); or (D) as provided in Section
(d)(3).

         (iii) In the event the determination of entitlement to indemnification
is to be made by Independent Counsel pursuant to Section (d)(2)(ii), a majority
of the Board of Directors shall select the Independent Counsel, but only an
Independent Counsel to which the Indemnitee does not reasonably object;
provided, however, that if a Change of Control shall have occurred, the
Indemnitee shall select such Independent Counsel, but only an Independent
Counsel to which the Board of Directors does not reasonably object.

         (iv) The only basis upon which a finding of no entitlement to
indemnification may be made is that indemnification is prohibited by law.

         (3) Presumptions and Effect of Certain Proceedings. Except as otherwise
expressly provided in this Article VIII, if a Change of Control shall have
occurred, the Indemnitee shall be presumed to be entitled to indemnification
under this Article VIII upon submission of a request
<PAGE>   294
                                                                    Exhibit 13-B
                                                                   Page 12 of 14


for indemnification together with the Supporting Documentation in accordance
with Section (d)(2)(i), and thereafter the Corporation shall have the burden of
proof to overcome that presumption in reaching a contrary determination. In any
event, if the person or persons empowered under Section (d)(2) to determine
entitlement to indemnification shall not have been appointed or shall not have
made a determination within 60 days after receipt by the Corporation of the
request therefor together with the Supporting Documentation, the Indemnitee
shall be deemed to be entitled to indemnification, and the Indemnitee shall be
entitled to such indemnification unless (A) the Indemnitee misrepresented or
failed to disclose a material fact in making the request for indemnification or
in the Supporting Documentation or (B) such indemnification is prohibited by
law. The termination of any Proceeding described in Section (a), or of any
claim, issue, or matter therein, by judgment, order, settlement, or conviction,
or upon a plea of nolo contendere or its equivalent, shall not of itself
adversely affect the right of the Indemnitee to indemnification or create a
presumption that the Indemnitee did not act in good faith and in a manner which
the Indemnitee reasonably believed to be in or not opposed to the best interests
of the Corporation or, with respect to any criminal Proceeding, that the
Indemnitee had reasonable cause to believe that the Indemnitee's conduct was
unlawful.

         (4) Remedies of Indemnitee.
         (i) In the event that a determination is made pursuant to Section
(d)(2) or (3) that the Indemnitee is not entitled to indemnification under this
Article VIII, (A) the Indemnitee shall be entitled to seek an adjudication of
his entitlement to such indemnification either, at the Indemnitee's sole option,
in (x) an appropriate court of the State of Delaware or any other court of
competent jurisdiction, or (y) an arbitration to be conducted by a single
arbitrator pursuant to the rules of the American Arbitration Association; (B)
any such judicial proceeding or arbitration shall be de novo and the Indemnitee
shall not be prejudiced by reason of such adverse determination; and (C) in any
such judicial proceeding or arbitration, the Corporation shall have the burden
of proving that the Indemnitee is not entitled to indemnification under this
Article VIII.

         (ii) If pursuant to Section (d)(2) or (3) a determination shall have
been made or deemed to have been made that the Indemnitee is entitled to
indemnification, the Corporation shall be obligated to pay the amounts
constituting such indemnification within five days after such determination has
been made or is deemed to have been made and shall be conclusively bound by such
determination unless (A) the Indemnitee misrepresented or failed to disclose a
material fact in making the request for indemnification or in the Supporting
Documentation, or (B) such indemnification is prohibited by law. In the event
that (X) advancement of expenses is not timely made pursuant to Section (d)(l),
or (Y) payment of indemnification is not made within five days after a
determination of entitlement to indemnification has been made or deemed to have
been made pursuant to Section (d)(2) or (3), the Indemnitee shall be entitled to
seek judicial enforcement of the Corporation's obligation to pay to the
Indemnitee such advancement of expenses or indemnification. Notwithstanding the
foregoing, the Corporation may bring an action in an appropriate court in the
State of Delaware or any other court of competent jurisdiction, contesting the
right of the Indemnitee to receive indemnification hereunder due to the
occurrence of an event described in subclause (A) or (B) of this clause (ii) (a
"Disqualifying Event"); provided, however, that in any such action the
Corporation shall have the burden of proving the occurrence of such
Disqualifying Event.

                                                                   Page 13 of 14


         (iii) The Corporation shall be precluded from asserting in any judicial
proceeding or arbitration commenced pursuant to this Section (d)(4) that the
procedures and presumptions of this Article VIII are not valid, binding, and
enforceable and shall stipulate in any such court or before any such arbitrator
that the Corporation is bound by all the provisions of this Article VIII.

         (iv) In the event that pursuant to this Section (d)(4) the Indemnitee
seeks a judicial adjudication of or an award in arbitration to enforce his
rights under, or to recover damages for breach of this Article VIII, the
Indemnitee shall be entitled to recover from the Corporation, and shall be
indemnified by the Corporation against, any expenses actually and reasonably
incurred by the Indemnitee if the Indemnitee prevails in such judicial
adjudication or arbitration. If it shall be determined in such judicial
adjudication or arbitration that the Indemnitee is entitled to receive part but
not all of the indemnification or advancement of expenses sought, the expenses
incurred by the Indemnitee in connection with such judicial adjudication or
arbitration shall be prorated accordingly.

         (5) Definitions. For purposes of this Section (d):
         (i) "Change in Control" means (A) so long as the Public Utility Holding
Company Act of 1935 is in effect, any "company" becoming a "holding company" in
respect to the Corporation or any determination by the Securities and Exchange
Commission that any "person" should be subject to the obligations, duties, and
liabilities if imposed by said Act by virtue or his, hers or its influence over
the management or policies of the Corporation, or (B) whether or not said Act is
in effect, a change in control of the Corporation of a nature that would be
required to be reported in response to Item 6(e) of Schedule 14A of Regulation
14A promulgated under the Securities Exchange Act of 1934 (the "Act"), whether
or not the Corporation is then subject to such reporting requirement; provided
that, without limitation, such a change in control shall be deemed to have
occurred if (i) any "person" (as such term is used in Section 13(d) and 14(d) of
the Act) is or becomes the "beneficial owner" (as defined in Rule 13d-3 under
the Act), directly or indirectly, of securities of the Corporation representing
10 percent or more of the combined voting power of the Corporation's then
outstanding securities without the prior approval of at least two-thirds of the
members of the Board of Directors in office immediately prior to such
acquisition; (ii) the Corporation is a party to a merger, consolidation, sale of
assets or other reorganization, or a proxy contest, as a consequence of which
members of the Board of Directors in office immediately prior to such
transaction or event constitute less than a majority of the Board of Directors
thereafter; or (iii) during any period of two consecutive years, individuals who
at the beginning of such period constituted the Board of Directors (including
for this purpose any new director whose election or nomination for election by
the Corporation's stockholders was approved by a vote of at least two-thirds of
the directors then still in office who were directors at the beginning of such
period) cease for any reason to constitute at least a majority of the Board of
Directors.

         (ii) "Disinterested Director" means a director of the Corporation who
is not or was not a party to the Proceeding in respect of which indemnification
is sought by the Indemnitee.

         (iii) "Independent Counsel" means a law firm or a member of a law firm
that neither presently is, nor in the past five years has been, retained to
represent: (A) the Corporation or the Indemnitee in any matter material to
either such party, or (B) any other party to the Proceeding giving rise to a
claim for indemnification under this Article VIII. Notwithstanding the
foregoing,
<PAGE>   296
                                                                    Exhibit 13-B

the term "Independent Counsel" shall not include any person who, under the
applicable standards of professional conduct then prevailing under the law of
the State of Delaware, would have a conflict of interest in representing either
the Corporation or the Indemnitee in an action to determine the Indemnitee's
rights under this Article VIII.

         (e) Severability. If any provision or provisions of this Article VIII
shall be held to be invalid, illegal or unenforceable for any reason whatsoever:
(i) the validity, legality, and enforceability of the remaining provisions of
this Article VIII (including, without limitation, all portions of any paragraph
of this Article VIII containing any such provision held to be invalid, illegal,
or unenforceable, that are not themselves invalid, illegal, or unenforceable)
shall not in any way be affected or impaired thereby; and (ii) to the fullest
extent possible, the provisions of this Article VIII (including, without
limitation, all portions of any paragraph of this Article VIII containing any
such provision held to be invalid, illegal, or unenforceable that are not
themselves invalid, illegal, or unenforceable) shall be construed so as to give
effect to the intent manifested by the provision held invalid, illegal, or
unenforceable.

         (f) Successor Laws, Regulations, and Agencies. Reference herein to
laws, regulations, or agencies shall be deemed to include all amendments
thereof, substitutions therefor, and successors thereto.

                                   ARTICLE IX

                                   AMENDMENTS

Bylaws may be adopted by the stockholders or by the Board of Directors, when
such power is conferred upon the Board of Directors by the Certificate of
Incorporation, at any regular meeting of the stockholders or of the Board of
Directors or at any special meeting of the stockholders or of the Board of
Directors if notice of such alteration, amendment, repeal, or adoption of new
Bylaws be contained in the notice of such special meeting.

final disposition, consistent with the provisions of applicable law as then in
effect.

         (b) Insurance, Contracts, and Funding. The Corporation may purchase and
maintain insurance to protect itself and any indemnitee against any expenses,
judgments, fines, and amounts paid in settlement as specified in Section (a) of
this Article VIII or incurred by an Indemnitee in connection with any proceeding
referred to in Section (a) of this Article VIII, to the fullest extent permitted
by applicable law as then in effect. The Corporation may enter into contracts
with any director, officer, employee, or agent of the Corporation or use other
means in furtherance of the provisions of this Article VIII to ensure the
payment of such amounts as may be necessary to effect indemnification as
provided in this Article VIII.

         (c) Indemnification; Not Exclusive Right. The right of indemnification
provided in this Article VIII shall not be exclusive of any other rights to
which those seeking indemnification may otherwise be entitled, and the
provisions of this Article VIII shall inure to the benefit of the heirs and
legal representatives of any person entitled to indemnity under this Article
VIII and shall be applicable to Proceedings commenced or continuing after the
adoption of this Article VIII, whether arising from acts or omissions occurring
before or after such adoption.

                                                                   Page 11 of 14


following procedures, presumptions, and remedies shall apply with respect to
advancement of expenses and the right to indemnification under this Article
VIII:

         (1) Advance of Expenses. All reasonable expenses incurred by or on
behalf of the Indemnitee in connection with any Proceeding shall be advanced to
the Indemnitee by the Corporation within 20 days after the receipt by the
Corporation of a statement or statements from the Indemnitee requesting such
advance or advances from time to time, whether prior to or after final
disposition of such Proceeding. Such statement or statements shall reasonably
evidence the expenses incurred by the Indemnitee and, if required by law at the
time of such advance, shall include or be accompanied by an undertaking by or on
behalf of the Indemnitee to repay the amounts advanced if it should ultimately
be determined that the Indemnitee is not entitled to be indemnified against such
expenses pursuant to this Article VIII.

         (2) Procedure for Determination of Entitlement to Indemnification.
         (i) To obtain indemnification under this Article VIII, an Indemnitee
shall submit to the Secretary of the Corporation a written request, including
such documentation and information as is reasonably available to the Indemnitee
and reasonably necessary to determine whether and to what extent the Indemnitee
is entitled to indemnification (the "Supporting Documentation"). The
determination of the Indemnitee's entitlement to indemnification shall be made
not later than 60 days after receipt by the Corporation of the written request
for indemnification together with Supporting Documentation. The Secretary of the
Corporation shall advise the Board of Directors in writing, promptly upon
receipt of such a request for indemnification, that the Indemnitee has requested
indemnification.

         (ii) The Indemnitee's entitlement to indemnification under this Article
VIII shall be determined in one of the following ways: (A) by a majority vote of
the Disinterested Directors (as hereinafter defined), even if they constitute
less than a quorum of the Board of Directors; (B) by a written opinion of
Independent Counsel (as hereinafter defined) if (x) a Change of Control (as
hereinafter defined) shall have occurred and the Indemnitee so requests or (y) a
quorum of the Board of Directors consisting of Disinterested Directors is not
obtainable or, even if obtainable, a majority of such Disinterested Directors so
directs; (C) by the stockholders of the Corporation (but only if a majority of
the Disinterested Directors present the issue of entitlement to indemnification
to the stockholders for their determination); or (D) as provided in Section
(d)(3).

         (iii) In the event the determination of entitlement to indemnification
is to be made by Independent Counsel pursuant to Section (d)(2)(ii), a majority
of the Board of Directors shall select the Independent Counsel, but only an
Independent Counsel to which the Indemnitee does not reasonably object;
provided, however, that if a Change of Control shall have occurred, the
Indemnitee shall select such Independent Counsel, but only an Independent
Counsel to which the Board of Directors does not reasonably object.

         (iv) The only basis upon which a finding of no entitlement to
indemnification may be made is that indemnification is prohibited by law.

         (3) Presumptions and Effect of Certain Proceedings. Except as otherwise
expressly provided in this Article VIII, if a Change of Control shall have
occurred, the Indemnitee shall be presumed to be entitled to indemnification
under this Article VIII upon submission of a request
<PAGE>   308
                                                                    Exhibit 14-B
                                                                   Page 12 of 14


for indemnification together with the Supporting Documentation in accordance
with Section (d)(2)(i), and thereafter the Corporation shall have the burden of
proof to overcome that presumption in reaching a contrary determination. In any
event, if the person or persons empowered under Section (d)(2) to determine
entitlement to indemnification shall not have been appointed or shall not have
made a determination within 60 days after receipt by the Corporation of the
request therefor together with the Supporting Documentation, the Indemnitee
shall be deemed to be entitled to indemnification, and the Indemnitee shall be
entitled to such indemnification unless (A) the Indemnitee misrepresented or
failed to disclose a material fact in making the request for indemnification or
in the Supporting Documentation or (B) such indemnification is prohibited by
law. The termination of any Proceeding described in Section (a), or of any
claim, issue, or matter therein, by judgment, order, settlement, or conviction,
or upon a plea of nolo contendere or its equivalent, shall not of itself
adversely affect the right of the Indemnitee to indemnification or create a
presumption that the Indemnitee did not act in good faith and in a manner which
the Indemnitee reasonably believed to be in or not opposed to the best interests
of the Corporation or, with respect to any criminal Proceeding, that the
Indemnitee had reasonable cause to believe that the Indemnitee's conduct was
unlawful.

         (4) Remedies of Indemnitee.
         (i) In the event that a determination is made pursuant to Section
(d)(2) or (3) that the Indemnitee is not entitled to indemnification under this
Article VIII, (A) the Indemnitee shall be entitled to seek an adjudication of
his entitlement to such indemnification either, at the Indemnitee's sole option,
in (x) an appropriate court of the State of Delaware or any other court of
competent jurisdiction, or (y) an arbitration to be conducted by a single
arbitrator pursuant to the rules of the American Arbitration Association; (B)
any such judicial proceeding or arbitration shall be de novo and the Indemnitee
shall not be prejudiced by reason of such adverse determination; and (C) in any
such judicial proceeding or arbitration, the Corporation shall have the burden
of proving that the Indemnitee is not entitled to indemnification under this
Article VIII.

         (ii) If pursuant to Section (d)(2) or (3) a determination shall have
been made or deemed to have been made that the Indemnitee is entitled to
indemnification, the Corporation shall be obligated to pay the amounts
constituting such indemnification within five days after such determination has
been made or is deemed to have been made and shall be conclusively bound by such
determination unless (A) the Indemnitee misrepresented or failed to disclose a
material fact in making the request for indemnification or in the Supporting
Documentation, or (B) such indemnification is prohibited by law. In the event
that (X) advancement of expenses is not timely made pursuant to Section (d)(l),
or (Y) payment of indemnification is not made within five days after a
determination of entitlement to indemnification has been made or deemed to have
been made pursuant to Section (d)(2) or (3), the Indemnitee shall be entitled to
seek judicial enforcement of the Corporation's obligation to pay to the
Indemnitee such advancement of expenses or indemnification. Notwithstanding the
foregoing, the Corporation may bring an action in an appropriate court in the
State of Delaware or any other court of competent jurisdiction, contesting the
right of the Indemnitee to receive indemnification hereunder due to the
occurrence of an event described in subclause (A) or (B) of this clause (ii) (a
"Disqualifying Event"); provided, however, that in any such action the
Corporation shall have the burden of proving the occurrence of such
Disqualifying Event.

                                                                   Page 13 of 14


         (iii) The Corporation shall be precluded from asserting in any judicial
proceeding or arbitration commenced pursuant to this Section (d)(4) that the
procedures and presumptions of this Article VIII are not valid, binding, and
enforceable and shall stipulate in any such court or before any such arbitrator
that the Corporation is bound by all the provisions of this Article VIII.

         (iv) In the event that pursuant to this Section (d)(4) the Indemnitee
seeks a judicial adjudication of or an award in arbitration to enforce his
rights under, or to recover damages for breach of this Article VIII, the
Indemnitee shall be entitled to recover from the Corporation, and shall be
indemnified by the Corporation against, any expenses actually and reasonably
incurred by the Indemnitee if the Indemnitee prevails in such judicial
adjudication or arbitration. If it shall be determined in such judicial
adjudication or arbitration that the Indemnitee is entitled to receive part but
not all of the indemnification or advancement of expenses sought, the expenses
incurred by the Indemnitee in connection with such judicial adjudication or
arbitration shall be prorated accordingly.

         (5) Definitions. For purposes of this Section (d):
         (i) "Change in Control" means (A) so long as the Public Utility Holding
Company Act of 1935 is in effect, any "company" becoming a "holding company" in
respect to the Corporation or any determination by the Securities and Exchange
Commission that any "person" should be subject to the obligations, duties, and
liabilities if imposed by said Act by virtue or his, hers or its influence over
the management or policies of the Corporation, or (B) whether or not said Act is
in effect, a change in control of the Corporation of a nature that would be
required to be reported in response to Item 6(e) of Schedule 14A of Regulation
14A promulgated under the Securities Exchange Act of 1934 (the "Act"), whether
or not the Corporation is then subject to such reporting requirement; provided
that, without limitation, such a change in control shall be deemed to have
occurred if (i) any "person" (as such term is used in Section 13(d) and 14(d) of
the Act) is or becomes the "beneficial owner" (as defined in Rule 13d-3 under
the Act), directly or indirectly, of securities of the Corporation representing
10 percent or more of the combined voting power of the Corporation's then
outstanding securities without the prior approval of at least two-thirds of the
members of the Board of Directors in office immediately prior to such
acquisition; (ii) the Corporation is a party to a merger, consolidation, sale of
assets or other reorganization, or a proxy contest, as a consequence of which
members of the Board of Directors in office immediately prior to such
transaction or event constitute less than a majority of the Board of Directors
thereafter; or (iii) during any period of two consecutive years, individuals who
at the beginning of such period constituted the Board of Directors (including
for this purpose any new director whose election or nomination for election by
the Corporation's stockholders was approved by a vote of at least two-thirds of
the directors then still in office who were directors at the beginning of such
period) cease for any reason to constitute at least a majority of the Board of
Directors.

         (ii) "Disinterested Director" means a director of the Corporation who
is not or was not a party to the Proceeding in respect of which indemnification
is sought by the Indemnitee.

         (iii) "Independent Counsel" means a law firm or a member of a law firm
that neither presently is, nor in the past five years has been, retained to
represent: (A) the Corporation or the Indemnitee in any matter material to
either such party, or (B) any other party to the Proceeding giving rise to a
claim for indemnification under this Article VIII. Notwithstanding the
foregoing,
<PAGE>   310
                                                                    Exhibit 14-B
                                                                   Page 14 of 14


the term "Independent Counsel" shall not include any person who, under the
applicable standards of professional conduct then prevailing under the law of
the State of Delaware, would have a conflict of interest in representing either
the Corporation or the Indemnitee in an action to determine the Indemnitee's
rights under this Article VIII.

         (e) Severability. If any provision or provisions of this Article VIII
shall be held to be invalid, illegal or unenforceable for any reason whatsoever:
(i) the validity, legality, and enforceability of the remaining provisions of
this Article VIII (including, without limitation, all portions of any paragraph
of this Article VIII containing any such provision held to be invalid, illegal,
or unenforceable, that are not themselves invalid, illegal, or unenforceable)
shall not in any way be affected or impaired thereby; and (ii) to the fullest
extent possible, the provisions of this Article VIII (including, without
limitation, all portions of any paragraph of this Article VIII containing any
such provision held to be invalid, illegal, or unenforceable that are not
themselves invalid, illegal, or unenforceable) shall be construed so as to give
effect to the intent manifested by the provision held invalid, illegal, or
unenforceable.

         (f) Successor Laws, Regulations, and Agencies. Reference herein to
laws, regulations, or agencies shall be deemed to include all amendments
thereof, substitutions therefor, and successors thereto.

                                   ARTICLE IX

                                   AMENDMENTS

Bylaws may be adopted by the stockholders or by the Board of Directors, when
such power is conferred upon the Board of Directors by the Certificate of
Incorporation, at any regular meeting of the stockholders or of the Board of
Directors or at any special meeting of the stockholders or of the Board of
Directors if notice of such alteration, amendment, repeal, or adoption of new
Bylaws be contained in the notice of such special meeting.

and each director elected shall hold office until his successor is elected and

the directors then in office, though less than a quorum, or by a sole remaining

election or until their successors are duly elected and shall quality, unless
sooner displaced. If there are no directors in office, then an election of

stockholders to fix the time or place of such first meeting of the newly elected
Board of Directors, or in the event such meeting is not held at the time and
place so fixed by the stockholders, the meeting may be held at such time and
place as shall be specified in a notice given as hereinafter provided for
special meetings of the Board of Directors, or as shall be specified in a

majority of the directors present at any meeting at which there is a quorum

specifically provided by statute or by the Certificate of Incorporation. If a
quorum shall not be present at any meeting of the Board of Directors, the
directors present thereat may adjourn the meeting from time to time, without
notice other than announcement at the meeting, until a quorum shall be present.

         Section 9. Unless otherwise restricted by the Certificate of
Incorporation or these Bylaws, any action required or permitted to be taken at
any meeting of the Board of Directors or of any committee thereof may be taken
without a meeting, if all members of the Board or committee, as the case may be,
consent thereto in writing, and the writing or writings are filed with the
minutes of proceedings of the Board or committee.

         Section 10. Unless otherwise restricted by the Certificate of
Incorporation or these Bylaws, members of the Board of Directors, or any
committee designated by the Board of Directors, may participate in a meeting of
the Board of Directors, or any committee, by means of conference telephone or
similar communications equipment by means of which all persons participating in
the meeting can hear each other, and such participation in a meeting shall
constitute presence in person at the meeting.

                             COMMITTEES OF DIRECTORS

         Section 11. The Board of Directors may, by resolution passed by a
majority of the whole Board, designate one or more committees, each committee to
consist of one or more of the directors of the Corporation. The Board may
designate one or more directors as alternate members of any committee, who may
replace any absent or disqualified member at any meeting of the committee. In
the absence or disqualification of a member of a committee, the member or
members thereof present at any meeting and not disqualified from voting, whether
or not he or they constitute a quorum, may unanimously appoint another member of
the Board of Directors to act at the meeting in the place of any such absent or
disqualified member. Any such committee, to the extent provided in the
resolution of the Board of Directors, shall have and may exercise all the powers

and/or to give the Corporation a bond in such sum as it may direct as indemnity

                                 INDEMNIFICATION

         (a) Right to Indemnification. The Corporation shall to the fullest
extent permitted by applicable law as then in effect indemnify any person (the
"Indemnitee") who was or is involved in any manner (including, without
limitation, as a party or a witness) or is threatened to be made so involved in
any threatened, pending or completed investigation, claim, action, suit or
proceeding, whether civil, criminal, administrative, or investigative (including
without limitation, any action, suit, or proceeding by or in the right of the
Corporation to procure a judgment in its favor) (a "Proceeding") by reason of
the fact that such person is or was a director, officer, employee, or agent of
the Corporation, or is or was serving at the request of the Corporation as a
director, officer, employee, or agent of another Corporation, partnership, joint
venture, trust, or other enterprise (including, without limitation, any employee
benefit plan) against all expenses (including attorneys' fees), judgments,
fines, and amounts paid in settlement actually and reasonably incurred by such
person in connection with such Proceeding. Such indemnification shall be a
contract right and shall include the right to receive payment of any expenses
incurred by the Indemnitee in connection with such Proceeding in advance of its
final disposition, consistent with the provisions of applicable law as then in
effect.

         (b) Insurance, Contracts, and Funding. The Corporation may purchase and
maintain insurance to protect itself and any indemnitee against any expenses,
judgments, fines, and amounts paid in settlement as specified in Section (a) of
this Article VIII or incurred by an Indemnitee in connection with any proceeding
referred to in Section (a) of this Article VIII, to the fullest extent permitted
by applicable law as then in effect. The Corporation may enter into contracts
with any director, officer, employee, or agent of the Corporation or use other
means in furtherance of the provisions of this Article VIII to ensure the
payment of such amounts as may be necessary to effect indemnification as
provided in this Article VIII.

         (c) Indemnification; Not Exclusive Right. The right of indemnification
provided in this Article VIII shall not be exclusive of any other rights to
which those seeking indemnification may otherwise be entitled, and the
provisions of this Article VIII shall inure to the benefit of the heirs and
legal representatives of any person entitled to indemnity under this Article
VIII and shall be applicable to Proceedings commenced or continuing after the
adoption of this Article VIII, whether arising from acts or omissions occurring
before or after such adoption.

         (d) Advancement of Expenses; Procedures; Presumptions and Effect of
Certain Proceedings; Remedies. In furtherance but not in limitation of the
foregoing provisions, the
<PAGE>   321
                                                                   Exhibit 15-B
                                                                   Page 11 of 14

following procedures, presumptions, and remedies shall apply with respect to
advancement of expenses and the right to indemnification under this Article
VIII:

         (1) Advance of Expenses. All reasonable expenses incurred by or on
behalf of the Indemnitee in connection with any Proceeding shall be advanced to
the Indemnitee by the Corporation within 20 days after the receipt by the
Corporation of a statement or statements from the Indemnitee requesting such
advance or advances from time to time, whether prior to or after final
disposition of such Proceeding. Such statement or statements shall reasonably
evidence the expenses incurred by the Indemnitee and, if required by law at the
time of such advance, shall include or be accompanied by an undertaking by or on
behalf of the Indemnitee to repay the amounts advanced if it should ultimately
be determined that the Indemnitee is not entitled to be indemnified against such
expenses pursuant to this Article VIII.

         (2) Procedure for Determination of Entitlement to Indemnification.

         (i) To obtain indemnification under this Article VIII, an Indemnitee
shall submit to the Secretary of the Corporation a written request, including
such documentation and information as is reasonably available to the Indemnitee
and reasonably necessary to determine whether and to what extent the Indemnitee
is entitled to indemnification (the "Supporting Documentation"). The
determination of the Indemnitee's entitlement to indemnification shall be made
not later than 60 days after receipt by the Corporation of the written request
for indemnification together with Supporting Documentation. The Secretary of the
Corporation shall advise the Board of Directors in writing, promptly upon
receipt of such a request for indemnification, that the Indemnitee has requested
indemnification.

         (ii) The Indemnitee's entitlement to indemnification under this Article
VIII shall be determined in one of the following ways: (A) by a majority vote of
the Disinterested Directors (as hereinafter defined), even if they constitute
less than a quorum of the Board of Directors; (B) by a written opinion of
Independent Counsel (as hereinafter defined) if (x) a Change of Control (as
hereinafter defined) shall have occurred and the Indemnitee so requests or (y) a
quorum of the Board of Directors consisting of Disinterested Directors is not
obtainable or, even if obtainable, a majority of such Disinterested Directors so
directs; (C) by the stockholders of the Corporation (but only if a majority of
the Disinterested Directors present the issue of entitlement to indemnification
to the stockholders for their determination); or (D) as provided in Section
(d)(3).

         (iii) In the event the determination of entitlement to indemnification
is to be made by Independent Counsel pursuant to Section (d)(2)(ii), a majority
of the Board of Directors shall select the Independent Counsel, but only an
Independent Counsel to which the Indemnitee does not reasonably object;
provided, however, that if a Change of Control shall have occurred, the
Indemnitee shall select such Independent Counsel, but only an Independent
Counsel to which the Board of Directors does not reasonably object.

         (iv) The only basis upon which a finding of no entitlement to
indemnification may be made is that indemnification is prohibited by law.

         (3) Presumptions and Effect of Certain Proceedings. Except as otherwise
expressly provided in this Article VIII, if a Change of Control shall have
occurred, the Indemnitee shall be presumed to be entitled to indemnification
under this Article VIII upon submission of a request
<PAGE>   322
                                                                   Exhibit 15-B
                                                                   Page 12 of 14

for indemnification together with the Supporting Documentation in accordance
with Section (d)(2)(i), and thereafter the Corporation shall have the burden of
proof to overcome that presumption in reaching a contrary determination. In any
event, if the person or persons empowered under Section (d)(2) to determine
entitlement to indemnification shall not have been appointed or shall not have
made a determination within 60 days after receipt by the Corporation of the
request therefor together with the Supporting Documentation, the Indemnitee
shall be deemed to be entitled to indemnification, and the Indemnitee shall be
entitled to such indemnification unless (A) the Indemnitee misrepresented or
failed to disclose a material fact in making the request for indemnification or
in the Supporting Documentation or (B) such indemnification is prohibited by
law. The termination of any Proceeding described in Section (a), or of any
claim, issue, or matter therein, by judgment, order, settlement, or conviction,
or upon a plea of nolo contendere or its equivalent, shall not of itself
adversely affect the right of the Indemnitee to indemnification or create a
presumption that the Indemnitee did not act in good faith and in a manner which
the Indemnitee reasonably believed to be in or not opposed to the best interests
of the Corporation or, with respect to any criminal Proceeding, that the
Indemnitee had reasonable cause to believe that the Indemnitee's conduct was
unlawful.

         (4) Remedies of Indemnitee.

         (i) In the event that a determination is made pursuant to Section
(d)(2) or (3) that the Indemnitee is not entitled to indemnification under this
Article VIII, (A) the Indemnitee shall be entitled to seek an adjudication of
his entitlement to such indemnification either, at the Indemnitee's sole option,
in (x) an appropriate court of the State of Delaware or any other court of
competent jurisdiction, or (y) an arbitration to be conducted by a single
arbitrator pursuant to the rules of the American Arbitration Association; (B)
any such judicial proceeding or arbitration shall be de novo and the Indemnitee
shall not be prejudiced by reason of such adverse determination; and (C) in any
such judicial proceeding or arbitration, the Corporation shall have the burden
of proving that the Indemnitee is not entitled to indemnification under this
Article VIII.

         (ii) If pursuant to Section (d)(2) or (3) a determination shall have
been made or deemed to have been made that the Indemnitee is entitled to
indemnification, the Corporation shall be obligated to pay the amounts
constituting such indemnification within five days after such determination has
been made or is deemed to have been made and shall be conclusively bound by such
determination unless (A) the Indemnitee misrepresented or failed to disclose a
material fact in making the request for indemnification or in the Supporting
Documentation, or (B) such indemnification is prohibited by law. In the event
that (X) advancement of expenses is not timely made pursuant to Section (d)(l),
or (Y) payment of indemnification is not made within five days after a
determination of entitlement to indemnification has been made or deemed to have
been made pursuant to Section (d)(2) or (3), the Indemnitee shall be entitled to
seek judicial enforcement of the Corporation's obligation to pay to the
Indemnitee such advancement of expenses or indemnification. Notwithstanding the
foregoing, the Corporation may bring an action in an appropriate court in the
State of Delaware or any other court of competent jurisdiction, contesting the
right of the Indemnitee to receive indemnification hereunder due to the
occurrence of an event described in subclause (A) or (B) of this clause (ii) (a
"Disqualifying Event"); provided, however, that in any such action the
Corporation shall have the burden of proving the occurrence of such
Disqualifying Event.

         (iii) The Corporation shall be precluded from asserting in any judicial
proceeding or arbitration commenced pursuant to this Section (d)(4) that the
procedures and presumptions of this Article VIII are not valid, binding, and
enforceable and shall stipulate in any such court or before any such arbitrator
that the Corporation is bound by all the provisions of this Article VIII.

         (iv) In the event that pursuant to this Section (d)(4) the Indemnitee
seeks a judicial adjudication of or an award in arbitration to enforce his
rights under, or to recover damages for breach of this Article VIII, the
Indemnitee shall be entitled to recover from the Corporation, and shall be
indemnified by the Corporation against, any expenses actually and reasonably
incurred by the Indemnitee if the Indemnitee prevails in such judicial
adjudication or arbitration. If it shall be determined in such judicial
adjudication or arbitration that the Indemnitee is entitled to receive part but
not all of the indemnification or advancement of expenses sought, the expenses
incurred by the Indemnitee in connection with such judicial adjudication or
arbitration shall be prorated accordingly.

         (5) Definitions. For purposes of this Section (d):

         (i) "Change in Control" means (A) so long as the Public Utility Holding
Company Act of 1935 is in effect, any "company" becoming a "holding company" in
respect to the Corporation or any determination by the Securities and Exchange
Commission that any "person" should be subject to the obligations, duties, and
liabilities if imposed by said Act by virtue or his, hers or its influence over
the management or policies of the Corporation, or (B) whether or not said Act is
in effect, a change in control of the Corporation of a nature that would be
required to be reported in response to Item 6(e) of Schedule 14A of Regulation
14A promulgated under the Securities Exchange Act of 1934 (the "Act"), whether
or not the Corporation is then subject to such reporting requirement; provided
that, without limitation, such a change in control shall be deemed to have
occurred if (i) any "person" (as such term is used in Section 13(d) and 14(d) of
the Act) is or becomes the "beneficial owner" (as defined in Rule 13d-3 under
the Act), directly or indirectly, of securities of the Corporation representing
10 percent or more of the combined voting power of the Corporation's then
outstanding securities without the prior approval of at least two-thirds of the
members of the Board of Directors in office immediately prior to such
acquisition; (ii) the Corporation is a party to a merger, consolidation, sale of
assets or other reorganization, or a proxy contest, as a consequence of which
members of the Board of Directors in office immediately prior to such
transaction or event constitute less than a majority of the Board of Directors
thereafter; or (iii) during any period of two consecutive years, individuals who
at the beginning of such period constituted the Board of Directors (including
for this purpose any new director whose election or nomination for election by
the Corporation's stockholders was approved by a vote of at least two-thirds of
the directors then still in office who were directors at the beginning of such
period) cease for any reason to constitute at least a majority of the Board of
Directors.

         (ii) "Disinterested Director" means a director of the Corporation who
is not or was not a party to the Proceeding in respect of which indemnification
is sought by the Indemnitee.

         (iii) "Independent Counsel" means a law firm or a member of a law firm
that neither presently is, nor in the past five years has been, retained to
represent: (A) the Corporation or the Indemnitee in any matter material to
either such party, or (B) any other party to the Proceeding giving rise to a
claim for indemnification under this Article VIII. Notwithstanding the
foregoing,
<PAGE>   324
                                                                   Exhibit 15-B

the term "Independent Counsel" shall not include any person who, under the
applicable standards of professional conduct then prevailing under the law of
the State of Delaware, would have a conflict of interest in representing either
the Corporation or the Indemnitee in an action to determine the Indemnitee's
rights under this Article VIII.

         (e) Severability. If any provision or provisions of this Article VIII
shall be held to be invalid, illegal or unenforceable for any reason whatsoever:
(i) the validity, legality, and enforceability of the remaining provisions of
this Article VIII (including, without limitation, all portions of any paragraph
of this Article VIII containing any such provision held to be invalid, illegal,
or unenforceable, that are not themselves invalid, illegal, or unenforceable)
shall not in any way be affected or impaired thereby; and (ii) to the fullest
extent possible, the provisions of this Article VIII (including, without
limitation, all portions of any paragraph of this Article VIII containing any
such provision held to be invalid, illegal, or unenforceable that are not
themselves invalid, illegal, or unenforceable) shall be construed so as to give
effect to the intent manifested by the provision held invalid, illegal, or
unenforceable.

         (f) Successor Laws, Regulations, and Agencies. Reference herein to
laws, regulations, or agencies shall be deemed to include all amendments
thereof, substitutions therefor, and successors thereto.

                                   ARTICLE IX

Directors or at any special meeting of the stockholders or of the Board of
Directors if notice of such alteration, amendment, repeal, or adoption of new

assistant treasurer shall give the Corporation a bond (which shall be renewed
every six years) in such sum and with such surety or sureties as shall be
satisfactory to the Board of Directors for the faithful performance of the

their death, resignation, retirement or removal from office, of all books,
papers, vouchers, money and other property of whatever kind in their possession
or under their control belonging to the Corporation.

         Section 14. The assistant treasurer, or if there shall be more than

refusal to act, perform the duties and exercise the powers of the treasurer and

         Section 2. Any of or all the signatures on the certificate may be
facsimile. In case any officer, transfer agent or registrar who has signed or

certificates to be issued in place of any certificate or certificates
theretofore issued by the Corporation alleged to have been lost, stolen or
destroyed, upon the making of an affidavit of that fact by the person claiming
the certificate of stock to be lost, stolen or destroyed. When authorizing such
issue of a new certificate or certificates, the Board of Directors may, in its
discretion and as a condition precedent to the issuance thereof, require the
owner of such lost, stolen or destroyed certificate or certificates, or his
legal representative, to advertise the same in such manner as it shall require
and/or to give the Corporation a bond in such sum as it may direct as indemnity
against any claim that may be made against the Corporation with respect to the
certificate alleged to have been lost, stolen or destroyed.

                               TRANSFERS OF STOCK

         Section 4. Upon surrender to the Corporation or the transfer agent of
the Corporation of a certificate for shares duly endorsed or accompanied by
proper evidence of succession, assignment or authority to transfer, it shall be
the duty of the Corporation to issue a new certificate to the person entitled
thereto, cancel the old certificate and record the transaction upon its books.

without a meeting, or entitled to receive payment of any dividend or other
distribution or allotment of any rights, or entitled to exercise any rights in
respect of any change, conversion or exchange of stock or for the purpose of any
other lawful action, the Board of Directors may fix, in advance, a record date,
which shall not be more than sixty nor less than ten days before the date of
such meeting, nor more than sixty days prior to any other action. A
determination of stockholders of record entitled to notice of or to vote at a
meeting of stockholders shall apply to any adjournment of the meeting; provided,
however, that the Board of Directors may fix a new record date for the adjourned
meeting.

         Section 6. The Corporation shall be entitled to recognize the exclusive
right of a person registered on its books as the owner of shares to receive

express or other notice thereof, except as otherwise provided by the laws of
Delaware.

                                    DIVIDENDS

subject to the provisions of the Certificate of Incorporation.

         Section 2. Before payment of any dividend, there may be set aside out
of any funds of the Corporation available for dividends such sum or sums as the
directors from time to time, in their absolute discretion, think proper as a
reserve or reserves to meet contingencies, or for equalizing dividends, or for
repairing or maintaining any property of the Corporation, or for such other
purpose as the directors shall think conducive to the interest of the

unless required by law, be signed by any two of the following officers: the
President, any Vice President, the Secretary, or any Assistant Secretary;
provided that in every case at least one such officer shall be the President, a
Vice President or the Secretary. The Board of Directors may, however,
notwithstanding the foregoing provision, by resolution adopted at any meeting,
authorize any of said officers or any employee of the Corporation so designated
by the Board of Directors of the Corporation to sign, checks, drafts, and such
orders for the payment of money singly and without necessity of
countersignature, and may designate officers of the Corporation other than those
named above or any employee of the Corporation so designated by the Board of
Directors of the Corporation, or different combinations of such officers or any
employee of the Corporation so designated by the Board of Directors of the

and such orders for the payment of money on its behalf. Further, the President
is authorized to designate to the Corporation's banks, in writing, individuals
employed in the Columbia Energy Group Service Corporation Cash Management
Department, who need not be officers or employees of the Corporation to give in
the name of the Corporation telephonic, telegraphic, or electronic transfer
instructions for the payment of money, which may, with respect to routine items,
include instructions as to the amount to be transferred, to any bank, pursuant
to previously issued written orders, signed by officers of the Corporation or by

                                  ARTICLE VIII
                                 INDEMNIFICATION
         (a) Right to Indemnification. The Corporation shall to the fullest
extent permitted by applicable law as then in effect indemnify any person (the
"Indemnitee") who was or is involved in any manner (including, without
limitation, as a party or a witness) or is threatened to be made so involved in
any threatened, pending or completed investigation, claim, action, suit or
proceeding, whether civil, criminal, administrative, or investigative (including
without limitation, any action, suit, or proceeding by or in the right of the
Corporation to procure a judgment in its favor) (a "Proceeding") by reason of
the fact that such person is or was a director, officer, employee, or agent of
the Corporation, or is or was serving at the request of the Corporation as a
director, officer, employee, or agent of another Corporation, partnership, joint
venture, trust, or other enterprise (including, without limitation, any employee
benefit plan) against all expenses (including attorneys' fees), judgments,
fines, and amounts paid in settlement actually and reasonably incurred by such
person in connection with such Proceeding. Such indemnification shall be a
contract right and shall include the right to receive payment of any expenses
incurred by the Indemnitee in connection with such Proceeding in advance of its
final disposition, consistent with the provisions of applicable law as then in
effect.

         (b) Insurance, Contracts, and Funding. The Corporation may purchase and
maintain insurance to protect itself and any indemnitee against any expenses,
judgments, fines, and amounts paid in settlement as specified in Section (a) of
this Article VIII or incurred by an Indemnitee in connection with any proceeding
referred to in Section (a) of this Article VIII, to the fullest extent permitted
by applicable law as then in effect. The Corporation may enter into contracts
with any director, officer, employee, or agent of the Corporation or use other
means in furtherance of the provisions of this Article VIII to ensure the
payment of such amounts as may be necessary to effect indemnification as
provided in this Article VIII.

         (c) Indemnification; Not Exclusive Right. The right of indemnification
provided in this Article VIII shall not be exclusive of any other rights to
which those seeking indemnification may otherwise be entitled, and the
provisions of this Article VIII shall inure to the benefit of the heirs and
legal representatives of any person entitled to indemnity under this Article
VIII and shall be applicable to Proceedings commenced or continuing after the
adoption of this Article VIII, whether arising from acts or omissions occurring
before or after such adoption.

         (d) Advancement of Expenses; Procedures; Presumptions and Effect of
Certain Proceedings; Remedies. In furtherance but not in limitation of the
foregoing provisions, the

<PAGE>   335
                                                                   Exhibit 16-B
                                                                   Page 11 of 14

following procedures, presumptions, and remedies shall apply with respect to
advancement of expenses and the right to indemnification under this Article
VIII:

         (1) Advance of Expenses. All reasonable expenses incurred by or on
behalf of the Indemnitee in connection with any Proceeding shall be advanced to
the Indemnitee by the Corporation within 20 days after the receipt by the
Corporation of a statement or statements from the Indemnitee requesting such
advance or advances from time to time, whether prior to or after final
disposition of such Proceeding. Such statement or statements shall reasonably
evidence the expenses incurred by the Indemnitee and, if required by law at the
time of such advance, shall include or be accompanied by an undertaking by or on
behalf of the Indemnitee to repay the amounts advanced if it should ultimately
be determined that the Indemnitee is not entitled to be indemnified against such
expenses pursuant to this Article VIII.

         (2) Procedure for Determination of Entitlement to Indemnification.
         (i) To obtain indemnification under this Article VIII, an Indemnitee
shall submit to the Secretary of the Corporation a written request, including
such documentation and information as is reasonably available to the Indemnitee
and reasonably necessary to determine whether and to what extent the Indemnitee
is entitled to indemnification (the "Supporting Documentation"). The
determination of the Indemnitee's entitlement to indemnification shall be made
not later than 60 days after receipt by the Corporation of the written request
for indemnification together with Supporting Documentation. The Secretary of the
Corporation shall advise the Board of Directors in writing, promptly upon
receipt of such a request for indemnification, that the Indemnitee has requested
indemnification.

         (ii) The Indemnitee's entitlement to indemnification under this Article
VIII shall be determined in one of the following ways: (A) by a majority vote of
the Disinterested Directors (as hereinafter defined), even if they constitute
less than a quorum of the Board of Directors; (B) by a written opinion of
Independent Counsel (as hereinafter defined) if (x) a Change of Control (as
hereinafter defined) shall have occurred and the Indemnitee so requests or (y) a
quorum of the Board of Directors consisting of Disinterested Directors is not
obtainable or, even if obtainable, a majority of such Disinterested Directors so
directs; (C) by the stockholders of the Corporation (but only if a majority of
the Disinterested Directors present the issue of entitlement to indemnification
to the stockholders for their determination); or (D) as provided in Section
(d)(3).

         (iii) In the event the determination of entitlement to indemnification
is to be made by Independent Counsel pursuant to Section (d)(2)(ii), a majority
of the Board of Directors shall select the Independent Counsel, but only an
Independent Counsel to which the Indemnitee does not reasonably object;
provided, however, that if a Change of Control shall have occurred, the
Indemnitee shall select such Independent Counsel, but only an Independent
Counsel to which the Board of Directors does not reasonably object.

         (iv) The only basis upon which a finding of no entitlement to
indemnification may be made is that indemnification is prohibited by law.

         (3) Presumptions and Effect of Certain Proceedings. Except as otherwise
expressly provided in this Article VIII, if a Change of Control shall have
occurred, the Indemnitee shall be presumed to be entitled to indemnification
under this Article VIII upon submission of a request
<PAGE>   336
                                                                   Exhibit 16-B
                                                                   Page 12 of 14

for indemnification together with the Supporting Documentation in accordance
with Section (d)(2)(i), and thereafter the Corporation shall have the burden of
proof to overcome that presumption in reaching a contrary determination. In any
event, if the person or persons empowered under Section (d)(2) to determine
entitlement to indemnification shall not have been appointed or shall not have
made a determination within 60 days after receipt by the Corporation of the
request therefor together with the Supporting Documentation, the Indemnitee
shall be deemed to be entitled to indemnification, and the Indemnitee shall be
entitled to such indemnification unless (A) the Indemnitee misrepresented or
failed to disclose a material fact in making the request for indemnification or
in the Supporting Documentation or (B) such indemnification is prohibited by
law. The termination of any Proceeding described in Section (a), or of any
claim, issue, or matter therein, by judgment, order, settlement, or conviction,
or upon a plea of nolo contendere or its equivalent, shall not of itself
adversely affect the right of the Indemnitee to indemnification or create a
presumption that the Indemnitee did not act in good faith and in a manner which
the Indemnitee reasonably believed to be in or not opposed to the best interests
of the Corporation or, with respect to any criminal Proceeding, that the
Indemnitee had reasonable cause to believe that the Indemnitee's conduct was
unlawful.

         (4)      Remedies of Indemnitee.
         (i) In the event that a determination is made pursuant to Section
(d)(2) or (3) that the Indemnitee is not entitled to indemnification under this
Article VIII, (A) the Indemnitee shall be entitled to seek an adjudication of
his entitlement to such indemnification either, at the Indemnitee's sole option,
in (x) an appropriate court of the State of Delaware or any other court of
competent jurisdiction, or (y) an arbitration to be conducted by a single
arbitrator pursuant to the rules of the American Arbitration Association; (B)
any such judicial proceeding or arbitration shall be de novo and the Indemnitee
shall not be prejudiced by reason of such adverse determination; and (C) in any
such judicial proceeding or arbitration, the Corporation shall have the burden
of proving that the Indemnitee is not entitled to indemnification under this
Article VIII.

         (ii) If pursuant to Section (d)(2) or (3) a determination shall have
been made or deemed to have been made that the Indemnitee is entitled to
indemnification, the Corporation shall be obligated to pay the amounts
constituting such indemnification within five days after such determination has
been made or is deemed to have been made and shall be conclusively bound by such
determination unless (A) the Indemnitee misrepresented or failed to disclose a
material fact in making the request for indemnification or in the Supporting
Documentation, or (B) such indemnification is prohibited by law. In the event
that (X) advancement of expenses is not timely made pursuant to Section (d)(l),
or (Y) payment of indemnification is not made within five days after a
determination of entitlement to indemnification has been made or deemed to have
been made pursuant to Section (d)(2) or (3), the Indemnitee shall be entitled to
seek judicial enforcement of the Corporation's obligation to pay to the
Indemnitee such advancement of expenses or indemnification. Notwithstanding the
foregoing, the Corporation may bring an action in an appropriate court in the
State of Delaware or any other court of competent jurisdiction, contesting the
right of the Indemnitee to receive indemnification hereunder due to the
occurrence of an event described in subclause (A) or (B) of this clause (ii) (a
"Disqualifying Event"); provided, however, that in any such action the
Corporation shall have the burden of proving the occurrence of such
Disqualifying Event.

                                                                   Exhibit 16-B
                                                                   Page 13 of 14


         (iii) The Corporation shall be precluded from asserting in any judicial
proceeding or arbitration commenced pursuant to this Section (d)(4) that the
procedures and presumptions of this Article VIII are not valid, binding, and
enforceable and shall stipulate in any such court or before any such arbitrator
that the Corporation is bound by all the provisions of this Article VIII.

         (iv) In the event that pursuant to this Section (d)(4) the Indemnitee
seeks a judicial adjudication of or an award in arbitration to enforce his
rights under, or to recover damages for breach of this Article VIII, the
Indemnitee shall be entitled to recover from the Corporation, and shall be
indemnified by the Corporation against, any expenses actually and reasonably
incurred by the Indemnitee if the Indemnitee prevails in such judicial
adjudication or arbitration. If it shall be determined in such judicial
adjudication or arbitration that the Indemnitee is entitled to receive part but
not all of the indemnification or advancement of expenses sought, the expenses
incurred by the Indemnitee in connection with such judicial adjudication or
arbitration shall be prorated accordingly.

         (5) Definitions. For purposes of this Section (d):
         (i) "Change in Control" means (A) so long as the Public Utility Holding
Company Act of 1935 is in effect, any "company" becoming a "holding company" in
respect to the Corporation or any determination by the Securities and Exchange
Commission that any "person" should be subject to the obligations, duties, and
liabilities if imposed by said Act by virtue or his, hers or its influence over
the management or policies of the Corporation, or (B) whether or not said Act is
in effect, a change in control of the Corporation of a nature that would be
required to be reported in response to Item 6(e) of Schedule 14A of Regulation
14A promulgated under the Securities Exchange Act of 1934 (the "Act"), whether
or not the Corporation is then subject to such reporting requirement; provided
that, without limitation, such a change in control shall be deemed to have
occurred if (i) any "person" (as such term is used in Section 13(d) and 14(d) of
the Act) is or becomes the "beneficial owner" (as defined in Rule 13d-3 under
the Act), directly or indirectly, of securities of the Corporation representing
10 percent or more of the combined voting power of the Corporation's then
outstanding securities without the prior approval of at least two-thirds of the
members of the Board of Directors in office immediately prior to such
acquisition; (ii) the Corporation is a party to a merger, consolidation, sale of
assets or other reorganization, or a proxy contest, as a consequence of which
members of the Board of Directors in office immediately prior to such
transaction or event constitute less than a majority of the Board of Directors
thereafter; or (iii) during any period of two consecutive years, individuals who
at the beginning of such period constituted the Board of Directors (including
for this purpose any new director whose election or nomination for election by
the Corporation's stockholders was approved by a vote of at least two-thirds of
the directors then still in office who were directors at the beginning of such
period) cease for any reason to constitute at least a majority of the Board of
Directors.

         (ii) "Disinterested Director" means a director of the Corporation who
is not or was not a party to the Proceeding in respect of which indemnification
is sought by the Indemnitee.

         (iii) "Independent Counsel" means a law firm or a member of a law firm
that neither presently is, nor in the past five years has been, retained to
represent: (A) the Corporation or the Indemnitee in any matter material to
either such party, or (B) any other party to the Proceeding giving rise to a
claim for indemnification under this Article VIII. Notwithstanding the
foregoing,
<PAGE>   338
                                                                   Exhibit 16-B
                                                                   Page 14 of 14


the term "Independent Counsel" shall not include any person who, under the
applicable standards of professional conduct then prevailing under the law of
the State of Delaware, would have a conflict of interest in representing either
the Corporation or the Indemnitee in an action to determine the Indemnitee's
rights under this Article VIII.

         (e) Severability. If any provision or provisions of this Article VIII
shall be held to be invalid, illegal or unenforceable for any reason whatsoever:
(i) the validity, legality, and enforceability of the remaining provisions of
this Article VIII (including, without limitation, all portions of any paragraph
of this Article VIII containing any such provision held to be invalid, illegal,
or unenforceable, that are not themselves invalid, illegal, or unenforceable)
shall not in any way be affected or impaired thereby; and (ii) to the fullest
extent possible, the provisions of this Article VIII (including, without
limitation, all portions of any paragraph of this Article VIII containing any
such provision held to be invalid, illegal, or unenforceable that are not
themselves invalid, illegal, or unenforceable) shall be construed so as to give
effect to the intent manifested by the provision held invalid, illegal, or
unenforceable.

         (f) Successor Laws, Regulations, and Agencies. Reference herein to
laws, regulations, or agencies shall be deemed to include all amendments
thereof, substitutions therefor, and successors thereto.

                                   ARTICLE IX

                                   AMENDMENTS
         Section 1. These Bylaws may be altered, amended, or repealed or new
Bylaws may be adopted by the stockholders or by the Board of Directors, when
such power is conferred upon the Board of Directors by the Certificate of
Incorporation, at any regular meeting of the stockholders or of the Board of

The parties hereby agree to allocate liabilities and benefits arising from such
consolidated return in the manner prescribed below which is consistent with Rule
45(c) of the Public Utility Holding Company Act of 1935:

(1)      Definitions:

         "Consolidated tax" is the aggregate current U.S. federal income tax
         liability for a tax year, being the tax shown on the consolidated
         federal income tax return and any adjustments thereto which are
         thereafter determined. If, because of a consolidated net operating
         loss, investment tax credit, carrybacks, etc., a refund is due, the
         consolidated tax for the current year will be that refund.

         "Separate return tax" is the tax on the corporate taxable income or
         capital of a company including the effect of any particular feature of
         the tax law, differences in tax rates, investment tax credits, etc.,
         applicable to it. Separate return tax may be either positive or
         negative.

(2)      The consolidated tax shall be apportioned among the members of the
         group utilizing the "separate return tax" method in the manner
         prescribed below:

         (a)      Intercompany eliminations recorded by consolidation entries
                  which affect the consolidated tax will be assigned to the
                  appropriate member necessitating the intercompany elimination
                  for the purpose of computing separate return tax.

         (b)      With the exception of the parent corporation, each member of
                  the group having negative separate return tax will receive
                  current payment in an amount equal to such negative separate
                  return tax if that member has sufficient taxable income in the
                  carryback period to utilize its negative separate return tax.
                  A member of the group that cannot utilize its negative
                  separate return tax on a stand alone basis either in the
                  current period or the permitted carryback period will not
                  receive payment for their negative separate return tax until
                  that member generates sufficient taxable income to utilize its
                  losses. The benefits of the negative separate

                                                                       Exhibit D
                                                                     Page 4 of 6


                     return tax not utilized currently by the member will serve
                     to reduce the tax payment obligation of the positive
                     separate return tax members. The positive separate return
                     tax member will record a liability to the Parent
                     Corporation for this reduction. The Parent Corporation
                     will record a liability for the negative separate return
                     tax to the loss member. Members with a negative separate
                     return tax will not participate in the allocation of the
                     parent corporation loss, if applicable, for that year.

                     If, because of carryback or other restrictions, the
                     aggregate of all negative separate return taxes is not
                     entirely usable in the current year"s return, the portion
                     which is usable will be apportioned among the members
                     having negative separate return tax in proportion thereto.

             (c)     Any parent corporation gain or loss realized from its sale
                     of its interest in subsidiaries" securities will be
                     assigned to parent corporation and will not be allocated to
                     other members. All other parent corporation negative
                     separate return tax will be allocated currently to positive
                     separate return tax members on the ratio of their positive
                     separate return tax to the total positive separate return
                     tax.

             (d)     Each member of the group, after intercompany eliminations,
                     having positive separate return tax will pay an amount
                     equal to its proportionate share of the consolidated tax
                     liability to members having negative separate return tax,
                     for which the separate return loss was utilized to offset
                     consolidated taxable income, based on the ratio of its
                     separate return tax to the total of the separate return
                     taxes of members having positive separate return tax,
                     assuming such loss companies meet the carryback requirement
                     of sub-section (b) above.

(3)      Carryover and other rights, if any, accrued under past regulations and
         orders for which a member company has not been paid shall be accounted
         for as follows: Each such member generating such benefits shall receive
         payment to the earliest year in which statutory carryover periods have
         not expired. Payment will be received, following execution of this
         agreement, from the companies which benefited from the prior deductions
         in the same ratios initially used to distribute such benefits.

(4)      In the event the consolidated return reflects a net operating loss or
         excess investment tax credit and cannot be totally carried back, the
         tax benefit of such net operating loss or excess shall be allowed as a
         carryover to future years. In the event they cannot be fully utilized
         on a consolidated basis, a proportionate allocation under Section (2)
         will be made. If and when the tax benefits are realizable on a
         consolidated basis in a subsequent year, such tax benefits shall be
         allocated to the members originally denied such benefits in the year
         the items were generated.

                                                                     Page 5 of 6


(5)      In the event the consolidated tax is subsequently materially revised by
         amended returns, interim payments or refunds, or, in any event, by a
         final determination, such changes shall be allocated in the same manner
         as though the adjustments on which they are based had formed part of
         the original consolidated return. The tax effect of negotiated
         adjustments which do not include an item-by-item modification of the
         return shall be allocated in accordance with Section (2)(d) of this
         agreement or, considering all the facts and circumstances, under such
         other method as may be determined to be more fair and equitable.

(6)      No subsidiary company, as a result of the method of allocation
         described herein, shall be required to pay more tax than its separate
         return tax as defined in Section (1).

(7)      Any current state income tax liability or benefit associated with a
         state income tax return or franchise tax return involving more than one
         member shall be allocated to such subsidiaries doing business in such
         state based on their separate return liabilities and other principles
         set forth herein.

         No member is to be allocated a state tax which is greater than its
         state tax liability had it filed a separate return, including the
         carryback/carryforward period . All available credits are to be
         allocated to the member generating the credit prior to the allocation
         of the System tax liability if available on a separate return basis.

         Similar to section 2(b) for federal income taxes, a member of the group
         that cannot utilize its negative separate return tax on a stand alone
         basis either in the current period or permitted carryback period will
         not receive payment for their negative separate return tax until that
         member generates sufficient taxable income to utilize its losses.

         In the event the consolidated state income tax liability for any year
         is redetermined subsequent to the allocation of the consolidated tax
         liability reported for that tax year, the redetermined tax liability
         shall be allocated pursuant to this Agreement as if the adjustments and
         modifications related to this determination had been a part of the
         original return. Any interest or penalties associated with underpayment
         or overpayment of tax shall be allocated based on the allocation of the
         underlying underpayment or overpayment of tax.

(8)      This agreement shall apply to the consolidated federal and state income
         tax returns to be filed for the calendar year 1996 and all subsequent
         years unless subsequently amended. In the case of unexpected events,
         including changes in the tax laws which may require modifications to
         the agreement, amendment to this agreement shall be conditioned on
         approval by the Securities and Exchange Commission.

                                                                     Page 6 of 6
