SECTION 16. LIABILITY OF THE PARTIES TO EACH OTHER.

    16.1 Liability Generally. Subject to the specific provisions of this Section
16, it is the intent of the Parties that each Party shall be liable to the other
Party for damages incurred as a result of the breach of this Agreement by the
other Party and failure to cure such breach as set forth in Section 17.1.2.

    16.2 Liability Restrictions.

         (a) SUBJECT TO SUBSECTION (b) BELOW, IN NO EVENT, WHETHER IN CONTRACT
    OR IN TORT (INCLUDING BREACH OF WARRANTY, NEGLIGENCE AND STRICT LIABILITY IN
    TORT), SHALL A PARTY BE LIABLE TO THE OTHER PARTY FOR INDIRECT OR
    CONSEQUENTIAL, EXEMPLARY, PUNITIVE OR SPECIAL DAMAGES EVEN IF SUCH PARTY HAS
    BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES IN ADVANCE.

         (b) The limitations set forth in subsection shall not apply to the
    indemnification obligations set forth in Section 15.3 and Section 15.4.

         (c) Each Party shall have a duty to mitigate damages for which the
    other Party is responsible.

         (d) Each Party shall be liable to the other Party for any actual

    Subcontractors or vendors

SECTION 17. INFORMAL DISPUTE RESOLUTION; ARBITRATION.

    17.1 Informal Dispute Resolution.



                                       37




         17.1.1 Role of Program Manager. In the event Incumbent has a dispute,
    controversy or other complaint relating to Pathnet's performance of
    Pathnet's rights and obligations under this Agreement, Incumbent shall have
    the right to first contact the Program Manager to resolve such dispute,
    controversy or other complaint. If Incumbent is not satisfied with the
    resolution provided by the Program Manager, Incumbent may resort to the
    arbitration procedures set forth in this Section 17.

         17.1.2 Notice of Breach, Cure and Remedies. In the event of a material
    breach by either Pathnet or Incumbent (the "Breaching Party"), the other
    Party (the "Non-Breaching Party") shall send by certified mail a written
    notice of such material breach to the Breaching Party setting forth the
    specific allegations of such breach. Upon receipt of the notice of breach,
    the Breaching Party shall have thirty (30) days to cure such breach. In the
    event the Breaching Party fails to cure such breach, as determined by the
    Non-Breaching Party in its sole discretion, and the Breaching Party
    determines, in its sole discretion, that it has cured such breach, either
    the Breaching Party or the Non-Breaching Party may invoke the arbitration

    as set forth in this Section 17.

         17.2.2 Referral to Binding Arbitration. Each Party shall have the

    award in any arbitration shall be final, conclusive and binding on the
    Parties and (ii) any such arbitration award be a final resolution of the
    Dispute between the Parties to the same extent as a final judgment of a
    court of competent jurisdiction.

         17.2.4 Use of Courts and Other Legal Remedies. Each Party covenants and
    agrees that it shall not resort to any court for legal remedies concerning
    any Dispute other than to enforce a final decision by the arbitrators or for
    preliminary, interim or provisional equitable relief in aid of arbitration.

         17.2.5 Arbitration Process.

         (a) Site and Arbitration Tribunal. Absent agreement to the contrary by
    the Parties, the arbitration will be conducted in New York, New York, by a

    years after notice of breach, such Party shall forever be barred from

      GROUNDING AND LIGHTNING PROTECTION GUIDELINES AND SPECIFICATIONS FOR
                             COMMUNICATIONS SHELTERS

Preface

An effective ground system for a communications equipment shelter is necessary
to ensure protection of personnel and equipment when a fault occurs. The ground
system limits excessive voltages from various electrical conditions such as
lightning and utility switching, and contributes to superior performance of the
electronic equipment by reducing noise induction.

1.    Grounding Introduction

Communications equipment shelters are subject to electrical noise and
high-voltage surges. These transients occur predominantly in the common mode
(line to ground), and are typically caused by lightning or power switching.

      1.1 Lightning

      When lightning induced surges appear at the point of connection to a
      building (the service entrance), a high common mode potential is generated
      between the current carrying conductors and ground. This potential
      produces a flow of current that seeks a path to earth to complete the
      circuit.

      Lightning can easily induce a 3000-ampere transient into a power line.
      When this transient reaches a building, the building ground at the service
      entrance can rise to 60,000 volts (assuming a building earth resistance of
      20 ohms). The reference potential for ground in the rest of the building
      would rise proportionately.

      In order to protect the building against these high voltage surges, it is
      important to establish a low resistance earth ground at the service
      entrance. The National Electrical Code (Article 250, Part 4) specifies
      that the grounding at a building's service entrance should have a
      resistance to ground of 25 ohms or less. The IEEE Green Book (Recommended
      Practice for Grounding, ANSI/IEEE Standard 142-1982) recommends that the
      ground resistance be less than 5 ohms. If the building contains highly
      sensitive electronic communications equipment, a ground resistance of 5
      ohms or less is recommended if this value can be practically achieved with
      the given site conditions.

      1.2 Types of Grounding

      There are two major types of grounding that should be considered when
      designing an electrical system: power distribution system grounding and
      telecommunications equipment grounding.

            1.2.1. Power Distribution System Grounding


                                      A-29


            The power distribution system pertains to the incoming AC service,
            service entrance equipment, power panels, and electrical conductors
            providing the power to various electrical/mechanical equipment.
            Grounding of the power distribution system is essential to:

            o     protect occupants from exposure to dangerous shock voltage
            o     provide a path for ground fault current
            o     limit excessive voltages due to lightning or utility switching

                  Typical grounding components for the power distribution system
                  include:

            o     grounding electrode at the service entrance
            o     ground bus in the power panel
            o     ground lugs in the other service entrance equipment such as
                  the safety disconnect or transfer switch
            o     third wire grounding conductor for all the electrical
                  equipment
            o     lightning and surge arresters.

            1.2.2. Telecommunications Equipment 

            Grounding Electronic equipment such as radio systems, telephone
            switches, battery chargers and rectifiers, uninterrupted power
            supply (UPS) equipment, and any other equipment that encloses or is
            adjacent to energized conductors require additional grounding. This
            sensitive electronic equipment must be protected from the following:

            o     excessive transients caused by lightning or utility switching
            o     degraded performance due to electromagnetic noise

            Equipment grounding frequently utilizes a ground ring encircling the
            interior of the shelter (halo ground ring). Ground lugs attached to
            the various equipment housings and racks are connected to the ground
            ring. Ground bars at the waveguide entry and at each section of the
            cable ladder are also tied to the ground ring. Multiple external
            drops connect the internal ground ring to the exterior site ground
            ring.

2.    Grounding Practices

      2.1. The Grounding Conductor

      In order to reduce inductance and surge voltages in a power distribution
      system, a ground path for protected devices should be provided. One method
      is to rely upon the conduit system to carry these transient currents. This
      is allowed by the National Electrical Code in Article 250-91 (b). The best
      method, however, is to include an extra conductor in the same conduit or
      raceway as the current carrying conductor. The grounding conductor should
      extend to the ground connection in the service entrance equipment.


                                      A-30


      2.2. Equipment Ground Wires

      When lightning strikes, it takes the path of least impedance (resistance
      and inductance). Cable bends increase inductance. Therefore, equipment
      ground wires should be large, and run straight for minimum inductance and
      voltage drop. The recommended bending radius is 6" when bends are
      unavoidable. Equipment ground wires should be separated from all other
      conductors, and should not be run through metal conduit unless the conduit
      and ground wires are bonded at both ends.

      2.3. Bonding

      Even when the ground to earth connection's impedance of the service
      entrance is minimized and grounding conductors are used in the feeder and
      branch circuits, high transient voltages can still occur in the power
      distribution system as a result of utility power switching. An effective
      method of limiting this noise (especially common mode voltage
      differentials) is to bond all the equipment ground wires to a halo ground
      system that is connected to the site ground system and power distribution
      system ground.

      Bonding is the connection of all potential ground conductors (including
      racks, frames, cable ladder, conduits, metal enclosures, and exposed
      metallic members of the building structure) to each other. Bonding does
      not eliminate voltage drops since transient currents will continue to take
      the path of least inductance. However, the current is sufficiently
      distributed throughout the bonded system to reduce the voltage gradients
      in any area to levels that prevent personal injury or equipment damage.

      Proper bonding procedures produce cross connections of all equipment and
      structures. It provides many paths to ground from any one point. Since the
      bonded ground network does not form a part of the normal electrical power
      path, multiple inductive loops are not a concern. Only transient or fault
      currents can flow in the ground network.

      In addition to preventing the development of voltage gradients, cross
      connection reduces the system's susceptibility to high frequency noise.
      Since all conductors have some impedance, resonance will occur at some
      frequencies. At those frequencies, the impedance of the grounding
      conductor may be very high, and allow noise currents to develop increased
      voltage drops. By bonding the ground network, however, there may be other
      conductors nearby that are not resonating, and a low impedance path for
      the noise signal can be maintained.

      2.4. Faraday Cage

      A Faraday cage provides an EMI shield to further reduce noise. The cage
      usually consists of multiple conductors in a box like configuration. A
      halo ground system with multiple down conductors can act as a quasi
      Faraday cage, and give some low frequency shielding.

      When lightning hits the tower, the tower will pass the current to ground
      and radiate RF energy. A Faraday cage can reduce this energy by adding
      distance (as seen by the 


                                      A-31


      magnetic field) between the tower and the equipment shelter. The steel
      reinforcing in the concrete shelter walls can form a highly effective
      Faraday cage if bonded to the grounding system. The amount of shielding
      depends on the size and spacing of the welded wire fabric. Additionally,
      all rebar must be bonded together.

      2.5. Site Ground System

      When a tower is struck by lightning, equipotential voltage rings form
      around the tower until the energy is diffused into the surrounding ground
      soil via the grounding system.

      The tower ground ring will disperse the energy away from the tower base or
      guy wires. The ground rods will transfer the energy deeper into more
      conductive soil layers. This is important to keep lightning surges out of
      the equipment shelter. Unless the energy is properly dispersed into the
      soil, the voltage will build up in the tower, and attempt to go to
      another, less desirable path.

      The equipment shelter is protected by a perimeter ground system that forms
      an equipotential plane. Also, ground rods should be driven into the soil
      at the following points:

      o     each corner of the shelter
      o     the service entrance
      o     the waveguide entry port
      o     each external halo ground drop
      o     every 10' (or less) along the exterior ground ring

      The shelter ground ring system should have a connection to the tower
      ground system just below the coaxial cable runs. A second connection
      between the two ground systems should be installed for redundancy. All
      metal work (waveguide bridge and supporting posts) should be bonded to the
      ring/radial ground system.

      2.6. Grounding System Performance Check

      Test the original installation periodically to determine whether
      resistance is remaining constant or is increasing. An increase in
      resistance can be caused by several factors.

      In lower conductive soils, high electric fields can develop at the ends of
      the ground rods, which can cause arcing in the soil. This arcing can cause
      glassification around the rods, beginning at the tip, and working its way
      upward. This glassification of the silica in the soil acts as an
      insulator, severely impairing the grounding characteristics of the rod. If
      resistance increases over time to an undesirable level, reduce the
      resistance by adding electrodes or chemically treating the soil to
      increase moisture content.

3.    Computing Resistance to Ground


                                      A-32


      3.1. Resistance to Earth

      The resistance of a grounding electrode is dependent on the:

      o     resistance of the electrode,
      o     contact resistance between the electrode and the soil, and
      o     resistance of the soil from the electrode surface outward as
            described by the geometry set up by the flow of current from the
            electrode to infinite earth.

      The first two resistances are negligible, and can be disregarded. The
      third resistance is larger and must be considered.

      Around a ground rod this resistance is the sum of the series resistances
      of virtual shells of earth, located progressively outward from the rod.
      The shell nearest the rod has the smallest circumferential area or cross
      section, so it has the highest resistance. Each successive shell has
      progressively larger areas, and thus, progressively lower resistances. For
      an 8-foot ground rod, the incremental increase in resistance decreases to
      nearly zero when the rods are spaced 16 feet apart. Therefore, when using
      multiple ground rods, the optimal spacing between rods should be double
      the length of the rod.

      3.2. Resistance Calculations

      When computing resistance to ground, treat the tower grounding and the
      shelter grounding as two separate systems. Within each of these two
      systems are two subsystems. The shelter has a grounding ring and the
      grounding rods. The tower has a grounding ring, grounding rods, and
      occasionally, grounding radials.

      The IEEE Green Book provides several formulas for calculating the
      resistance to ground for several different systems.

4.    Typical Grounding Configurations

Several options are available when deciding on a ground system for a
communication shelter, depending upon the soil conditions and thunderstorm
activity of a particular site. The U.S. Weather Bureau publishes an isoplethic
map of the United States showing the average number of days each year on which
thunderstorms occur. Any area with an isoplethic level above 90 should be
considered a high-risk area, and serious consideration should be given to
providing a more stringent grounding system.

      4.1. Ground Bar System

      In shelters where very little lightning protection is needed, a simple
      ground bar system can be used. A system of this type would consist of a
      single copper ground bar located under the waveguide port, telephone
      entry, or both, with an external drop to be connected to the external
      ground system. Transmission lines should be grounded to this ground bar.


                                      A-33


      4.2. Halo Ground System

      Pathnet shelters will use a halo ground system. This system includes a #2
      AWG copper wire completely encircling the equipment room. The halo is
      located 3 to 6 inches below the ceiling. External drops are located at
      each corner of the shelter. Wall penetrations should be angled at 45
      degrees to minimize bending.

      4.3. External Ground System

      The external ground system for all shelters consists of ground rods placed
      at each corner of the shelter and 10' intervals along the ground ring,
      below the waveguide entry, and at the AC service entrance. The rods should
      be exothermically welded to a perimeter ground ring of #2 AWG solid tinned
      copper wire. (Tinned copper is recommended to reduce corrosion of the
      wire). The wire should be buried below the frost line (minimum 30", deep
      per NEC Sec 250-8(d)), and at least 24", away (measured horizontally) from
      the foundation. The ground ring should be bonded to the tower ground
      system at two locations, to the externally mounted ground bars under the
      waveguide ports and to the AC service ground as close as possible to the
      service entrance.

5.    General Specifications

This section covers grounding and lightning protection of pre-cast,
pre-equipped, and transportable equipment shelters. It establishes minimum
standards for grounding of all Pathnet Equipment Shelters, and provides
standards for additional customer grounding options.

      5.1. General Guidelines

            5.1.1 Workmanship

            Equipment grounding wire conductor runs will be as short and
            straight as possible. All equipment and bonding grounding conductors
            will have radii bends 6" or greater.

            5.1.2. Design

            Where possible, the AC service entrance, waveguide entry port, and
            telephone line entry will all be located in close proximity to each
            other, and their associated grounding systems will be bonded
            together.

            5.1.3. Connections

            Unless specified otherwise, minimum connection requirements will be
            of the mechanical type made with a crimp type connector. A one hole
            copper ground lug will be used for equipment connections. An
            oxidizing preventative compound will be applied to all mechanical
            connections, and paint will be removed as necessary to insure
            positive bonding of all grounded equipment.


                                      A-34


            All external, buried connections will be of the exothermically
            welded type. These include, but are not limited to, halo drops to
            ground rod, buried ground ring to ground rod, halo drops to ground
            ring, service entrance ground to ground rod.

            5.1.4. Wire

            All equipment grounds will be #6 AWG. Circuit grounding conductors
            will be no more than two wire sizes smaller than the current
            carrying conductors of the same circuit (minimum #12 AWG). All
            external ground wire, including but not limited to the external
            ground ring and external halo drops, will be #2 AWG solid tinned
            copper.

      5.2   Interior Grounding

            5.2.1. Halo Ground

            The halo ground will consist of a minimum #2 AWG wire located 3" to
            12", below the finished ceiling, and will completely encircle the
            equipment room. The wire will be green insulated stranded copper,
            bare stranded copper, or bare tinned solid copper. Each corner of
            the equipment room will have an omni-directional drop to the floor
            of the same wire size and type as the halo ring. Connection of these
            drops to the halo will be at least the defined minimum (see section
            5.1.3). If solid tinned wire is used, the drop will be one
            continuous wire that is long enough to extend 8 feet beyond the
            exterior of the shelter. If insulated wire is used, the drop will
            extend to the floor, and then be connected in the same manner as the
            halo, to an 8-foot length of solid tinned wire of the same size. The
            exterior penetrations will be at 45 degree angles (to minimize
            ground drop bend radii) and approximately one (1) inch in diameter.

            5.2.2. Waveguide Entry Ground Bar

            There will be a 1/4" x 4" x 20" (minimum) copper ground bar located
            outside the shelter approximately 6" below the waveguide entry plate
            (NEC Sec 800-33). This bar will be connected to the exterior ground
            ring exothermic weld. The grounding conductor will be of the same
            size and type as the halo ring.

            5.2.3. AC Service

            The AC service ground conductor will be bonded to the ground rod
            located at the service entrance. Ground lugs provided in all service
            entrance equipment will be bonded to the service ground conductor.
            The system ground and neutral will be bonded at one location, as
            close as practicable to the service entrance. All service grounding
            shall conform to Article 250 of the National Electrical Code.

            5.2.4. Primary Surge Arrester


                                      A-35


            There will be a surge protective device applied at the first piece
            of service equipment inside the equipment shelter. This device will
            be considered the primary surge protector. Conductors connecting the
            surge protective device will be as short as possible, and will
            contain no sharp bends or loops.

            The operating characteristics of the primary surge arrester will
            coordinate with the equipment surge withstand voltage capabilities.
            The surge arrester should be capable of suppressing up to 65kVA, be
            self restoring after operation, and may be equipped with a failure
            alarm over current protective device and visual status indicators.

            5.2.5. Cable Ladder

            Cable ladder assemblies will be bonded to the halo ring with a #6
            AWG or larger ground conductor. All cable ladder splices and
            junctions will be bonded on at least one side with a #6 AWG or
            larger conductor, and use grounding clips suitable for the purpose.
            Paint will be removed as necessary for an electrically sound
            connection.

            5.2.6. Conduit Grounding

            Each conduit discontinuity, including but not limited to conduit
            couplings, junction boxes, light fixtures, and service equipment,
            will be provided with ground clamps to electrically bond the
            conduit. The bonding wire will be green insulated #6 AWG or larger.

            5.2.7. Tower Light Controller Penetration

            There will be a 1-1/2" penetration cast in place near the waveguide
            entry port to allow for connection of the tower light controller.
            The penetration will be lined with a 1" PVC running thread to
            provide isolation between the interior and exterior conduit. The
            running thread will be connected to interior and waterproof exterior
            6" x 6" junction boxes.

      5.3.  Exterior Grounding

            5.3.1. Ground Rods

            There will be driven ground rods located at each corner of the
            building, and at the AC service entrance and waveguide entry port.
            These rods will be made of copper clad high strength steel with
            minimum dimensions of 5/8" x 8'. The rods will be located at least
            24" from the edge of the foundations, and driven such that the top
            of the rod is below the frost line of the installation site. The
            rods will be exothermically welded to the external halo drops.

            5.3.2. Ground Ring


                                      A-36


            There will be a buried horizontal wire completely encircling the
            equipment shelter. This wire will be solid tinned copper wire of #2
            AWG or larger. The ground ring will not be closer than 24" from the
            shelter foundations, and will be exothermically welded to each
            ground rod. The ring will be buried 30" below grade or below the
            frost line of the installation, whichever is greater.

            The ground ring will be connected to the tower ground system from
            the ground rod located at the waveguide port to the nearest ground
            rod of the tower system. A second connection will be made from a rod
            at a corner of the shelter to an alternate rod of the tower. These
            connections will be made with a #2 AWG wire, or a wire of the same
            size as the tower ground ring, whichever is larger.

            5.3.3. Testing

            The external ground system will be tested after installation, and
            its resistance to earth ground will be less than 10 ohms. It is
            recommended that tests be performed twice a year to insure ground
            system integrity.

            Biddle Instruments Model DET2/2 Digital Ground Tester, or
            equivalent, will be used for testing and all manufacturers'
            instructions will be followed.

WHEREAS, K N Energy, Inc., and its employees acknowledge that substance abuse is
a serious and complex, but treatable condition that negatively affects the
productive, personal and family lives of employees and the stability of
companies; and

WHEREAS, K N Energy, Inc., and its employees are committed to addressing the
problems of substance time to ensure the safety of the working environment
personal and public safety, by providing employees access to necessary treatment
and rehabilitation assistance; and

WHEREAS, K N Energy, Inc., has provided a program of employee assistance and has
generally provided the availability of medical coverage allowing employees
requiring treatment and rehabilitation for substance abuse to receive the
services without undue financial hardship; and

WHEREAS, appropriate efforts will be made by K N Energy, Inc., to establish
employee understanding that the experience of a drug or alcohol problem is not,
of itself, grounds for adverse action. Employees will be strongly encouraged to
seek and receive the services of the Employee Assistance Program prior to such a
problem affecting job performance or resulting in an on-the-job incident;

NOW, THEREFORE, it is the policy of K N Energy, Inc., and its affiliates,
hereinafter collectively called the "Company," that no employee shall
manufacture, distribute, possess, use or have in their system, illegal drugs,
drug paraphernalia, alcohol or other unauthorized controlled substances while on
the job.

PURPOSE

The purpose and intent of this policy is:

      o     to provide a safe, healthy and productive working environment for
            all employees

      o     to ensure the reputation and integrity of the Company and its
            employees

      o     to reduce the incidence of accidental injury to persons or property

      o     to reduce absenteeism, tardiness and indifferent job performance

      o     to provide assistance toward rehabilitation for any employee seeking
            help in overcoming dependence and addiction with alcohol or drugs

COOPERATION

The Company earnestly asks for the understanding and cooperation of all
employees in implementing the Alcohol and Drug Abuse Policy, and the Company
regrets any inconvenience that may be caused the many non-abusers of drugs and
alcohol. We believe, however, that benefits to be derived from the reduction in
number and severity of accidents, greater safety of all employees and of the
public and rehabilitation or termination of those who, became of alcohol or
drugs, are a burden upon all other employees, will more than make up for any
discomfort the rest may experience.

      pipeline or LNG facility, and the function is regulated by the DOT
      regulation CFR49 Parts 192, 193, and 195.

Specimen

      A sample of urine, saliva or breath to be used in analysis for the
      presence of drugs or alcohol.

Substance Abuse Professional (SAP)

      A licensed physician, or a licensed certified psychologist, social worker,
      employee assistance professional, or addiction counselor (Certified by the
      National Association of Alcoholism and Drug Abuse Counselors Certification
      Commission), with knowledge of and clinical experience in diagnosis and
      treatment of alcohol-related disorders.

DRUG-FREE AWARENESS PROGRAM

The Company is a Drug-Free Awareness program to assist employees and their
families in understanding and avoiding problems associated with drug and alcohol
abuse. The Company will use this program as an educational tool to and in the
prevention and elimination of drug and alcohol abuse that could affect the
workplace. The Drug-Free Awareness program will inform employees and their
families on the following:

      o     the dangers of alcohol and drug abuse

      o     the Company's Alcohol and Drug Abuse Policy

      o     the availability of treatment and counseling for those voluntarily
            seeking assistance

      o     sanctions the Company will impose for violations of the Alcohol and
            Drug Abuse Policy.

A copy of the Company's Alcohol and Drug Abuse Policy booklet will be issued to
all employees covered by the policy. This information will be periodically
updated to keep employees informed on any changes to the Alcohol and Drug Abuse
Policy and information associated with the EAP. The information will be
communicated to employees on bulletin boards, employee mailings and various
other forms available at the time.

TREATMENT FOR SUBSTANCE ABUSE

Successful treatment of substance abuse is, to a great degree, dependent upon
the desire of the abuser to overcome the disease and his/her willingness to seek
proper treatment. The Company encourages voluntary drug or alcohol abuse
treatment and will be supportive of employees and/or their dependents who seek
treatment of their own accord. Conversely, the Company will take strong action
against those employees who suffer from drug or alcohol abuse, but who refuse to
seek treatment for the problem.

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

If an employee tests positive for drugs or alcohol after being referred for
mandatory testing because of declining job performance or erratic on-the-job
behavior, that employee is in violation of the Company's Alcohol and Drug Abuse
Policy.

Any employee who has reason to suspect another employee or supervisor may be
abusing drugs or alcohol is encouraged to contact the Company's program
administrator, who will evaluate the situation and determine what steps should
be taken. Employees can be assured they may take such action on a confidential
basis and without fear of reprisal.

AUTHORIZED USE OF PRESCRIBED MEDICINE

An employee who is receiving medical treatment with any prescribed medication
which may alter his/her on-the-job behavior, physical or mental ability shall
report this medication is being taken to their immediate supervisor, who shall
seek guidance in determining whether the Company should temporarily change the
employee's job assignment during the period of treatment.

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

All records and information regarding alcohol and drug testing, test results,
and treatment of employees for chemical dependency will be confidentially
maintained by the Company. Access to information will be on a need-to-know
basis. When requested in writing, individual employees will have the right to
request information from his/her file pertaining to specific test results and
other information regarding the testing laboratory's findings. Specific
information on the testing laboratory or collection sites will be obtained
through the Program Administrator in Lakewood.

Information regarding an individual's alcohol and/or drug testing results or
rehabilitation may be released only upon the written consent of that individual.
An exception to this rule would be if information is requested in writing from
the DOT Administrator or another regulatory having regulatory authority over the
Company. In this instance, the Company is obligated by law to release the
information requested, whether the employee grants permission or not.

The laboratory maintaining confidential employee test records must, upon request
disclose information related to a positive alcohol and/or drug test of an
employee to the employee or the decision-maker in a lawsuit complaint procedure
or other proceeding initiated on behalf of the employee arising from the
positive test.

TESTING METHODOLOGY

Alcohol and drug testing shall be conducted through methods with proven
reliability and in strict compliance with appropriate methodology allowed by DOT
regulations. All drug tests will be conducted using only U.S. Department of
Health and Human Services NIDA-certified labs. If an employee fails to pass the
initial drug screening test, the original test specimen will be further analyzed
using the gas chromatography/mass spectrometry method, and verified by a
Company-designated MRO before any Company action is taken. A positive alcohol
screening test will be followed by a confirming test in accordance with
conditions specified by DOT regulations.

INSPECTIONS

The Company has the right at any time, to conduct unannounced inspections for
unauthorized alcohol or illegal drugs in or on Company property and vehicles.

EMPLOYEES IN SAFETY-SENSITIVE POSITIONS

The Company's program administrator will maintain a list of sensitive safety-
related jobs and employees who hold such positions shall be notified. The list
of safety-sensitive functions will be posted throughout the Company regions as
general information for the employees. Employees holding safety-sensitive
positions will, in addition to this policy, be subject to the provisions of the
Anti-Drug Plan covered Section G1.50 and the Alcohol Abuse Prevention Plan
covered in Section G1.55 of the Company's Standard Practices manual. Both plans
conform to the specific requirements of DOT regulations.

CONSEQUENCES FOR VIOLATION OF DRUG AND ALCOHOL POLICY

Violation of the Company's Alcohol and Drug Abuse Policy may, at the Company's
sole discretion, result in severe disciplinary action up to and including
termination for a first offense. The employee who tests positive for alcohol or
drugs will be removed from the job until he/she has:

      o     communicated with the Company's EAP for assessment and counseling

      o     successfully completed the rehabilitation program recommended by the
            MRO or SAP

      o     been approved by the MRO or SAP for return to duty after
            rehabilitation

      o     passed a return-to-duty drug or alcohol test


                                        7


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

1.    The requirement for this testing shall be implemented in accordance with
      the following procedures:

      (a)   When a supervisor has established reasonable cause that at employee
            may be under the influence of drugs or alcohol, based upon specific
            individualized observations, the supervisor shall contact another
            supervisor or management employee for the purpose of confirming the
            reasonable cause. The second observation will be obtained whenever
            possible, and does not a require the confirming supervisor to
            personally observe the employee in question. Concurrence can be
            given over the telephone.

            Once reasonable cause has been established, the employee shall be
            taken from the job to a collection site to provide a specimen to be
            tested by the supervisor. Under no circumstance shall the employee
            being tested be allowed to drive to the collection site. If the
            testing results are positive, the employee will have the opportunity
            to immediately self-refer to the Employee Assistance Program (EAP).
            If the test is positive for alcohol, the employee will be referred
            to the SAP for evaluation and/or treatment.

      (b)   Any employee who refuses to go to a collection facility to provide a
            urine, saliva, or breath specimen for testing, or who does not
            immediately self-refer to the EAP/SAP following a confirmed positive
            test, shall be terminated.

            If required, the employee must sign a consent form authorizing the
            collection facility to collect a urine, saliva or breath specimen.
            By signing the consent form, the employee does not waive any claim
            or cause of action under the law. An employee's refusal to sign the
            required consent form shall constitute a refusal to be tested under
            the provisions of Section 1(c) below.

      (c)   Any employee who refuses to be tested will be encouraged to go to
            the collection facility to provide a specimen with the understanding
            that the urine specimen obtained will not be tested unless that
            employee, within the following twenty-four (24) hours, authorizes
            that the specimen be tested. If, at the end of the 24-hour period,
            the employee still refuses to have the specimen tested, the employee
            shall be terminated.

      (d)   The employee to be tested shall be taken to the collection facility
            by a Company representative. The covered employee, if represented by
            a bargaining unit, may request another bargaining unit employee be
            present at the collection site during the specimen collection
            process. The specimen collection shall not be unduly delayed while
            awaiting the fellow employee's arrival. Any expense associated with
            the presence of the fellow employee shall be the responsibility of
            the union or the employee being tested.

      (e)   In an effort to protect individual privacy, employees will not be
            subject to direct observation while rendering a urine specimen. If
            the employee provides a specimen that contains confirmed evidence of
            any form of alteration, tampering, or substitution, this act
            constitutes a refusal to be tested and the employee shall be
            terminated.

      (f)   All urine specimens will be collected using the "split-sample"
            method. This applies to both RSPA and FHWA functions within the
            company. Specimens that yield positive results will be retained by
            the laboratory in properly secured long-term storage for a period
            of up to as year. If the MRO determines there is no legitimate
            medical explanation for the confirmed positive result other than the
            unauthorized use of a prohibited drug, the original sample must be
            re-tested if the employee makes a written request for re-testing
            within 60 days of receipt of the final test result from the MRO. The
            employee may specify re-testing by the original lab or by another
            NIDA-certified laboratory. An employee requesting an independent
            test is responsible for the costs of the second test, unless the
            employee's second test results are negative.

            In the case of re-testing an employee holding a CDL, the time
            allowed for the notice requesting a second test is the following 72
            hours under FHWA rules, instead of the 60 days allowed under RSPA
            rules. Except for the abbreviated time allowed for notice, all other
            aspects of the re-testing procedures shall be the same.

            Since some analytes may deteriorate during storage, detected levels
            of a drug below the detection limits established in the DOT
            procedures, but equal to or greater than the established sensitivity
            of the assay,


                                        9

            collection room to receive containers, assure that the quantity of
            the urine is sufficient for testing, check urine color and measure
            and record urine temperature. Collection personnel shall fill in
            specimen labels while in the presence of the employee and shall cap
            and seal containers with evidence tape and secure the employee's
            initials on the evidence tape.

      o     Proper chain-of-custody procedures governing specimen handing
            throughout the testing process. Chain-of-custody procedures shall
            assure that a urine specimen shall not leave the sight of the
            employee until each specimen container has been sealed and initialed
            by the employee giving the specimen.

      o     Authorized collection facility personnel shall seal specimen tubes
            with evidence tape in the presence of the employee and the employee
            shall then initial the evidence tape. The collector will complete a
            chain-of-custody form and shall place the sealed and initialed
            specimen tubes in the drug collection kit or box provided by the
            laboratory, along with the chain-of-custody form. The collection kit
            or box shall be sealed and initialed by the collector.

            The collection facility shall assure that all specimens are
            couriered or shipped to the testing laboratory as immediately as
            possible. The collection facility shall assure that any specimens
            held at the facility overnight will be placed in a secured
            refrigerator until courier pickup.

      o     The testing laboratory shall assure that personnel authorized to
            receive specimens immediately open the package, inspect the sealing
            tape for initials and open the kit or box. Lab personnel shall
            examine and inspect the chain-of-custody form, the specimen tubes
            and kit or box to assure that it conforms to the requirements of DOT
            Part 40 regulations. If these requirements are not met, the
            laboratory personnel shall immediately notify the laboratory's
            scientific director and shall document any and all inadequacies in
            the chain-of-custody requirements. The laboratory's scientific
            director shall immediately notify the collection facility and/or the
            Company's program administrator of the inadequacies and shall retain
            the specimens in a locked freezer pending disposition directions.

      o     If these requirements are met, authorized laboratory personnel shall
            sign on the appropriate line of the chain-of-custody form and
            deliver the specimen kit or box to authorized laboratory
            technologists for testing.

      o     All positive samples shall be secured with evidence tape, signed and
            dated by an authorized technologist. Upon completion of testing
            procedures, testing reports shall be prepared and signed by the
            technologist for the review, approval and signature of the
            scientific director.

      o     Levels below which specimens are deemed negative shall correspond to
            those established by DOT guidelines, as amended from time to time.

      o     Laboratory use of appropriate screening and confirmation procedures
            and technology.

      o     The laboratory shall assure that each specimen will be screened by
            an immunoassay method (i.e., EMIT, RIA or FPI) for each drug/drug
            group.

      o     All specimens identified as positive shall be confirmed using gas
            chromatography/mass spectrometry (GC/MS) techniques. The laboratory
            shall report as negative all specimens which are negative on the
            initial test or negative on the confirmatory test. Only specimens
            confirmed positive on the initial test and also the confirmatory
            test shall be reported as a positive test.

      o     Screening methods measure a group of drugs and/or their metabolites
            simultaneously. Confirmatory methods, on the other hand, measure
            single and specific drugs and/or their metabolites. Established
            levels for confirmatory methods, therefore, may be lower than those
            for initial screening.

      o     A specimen testing positive must be preserved in properly secured,
            long-term frozen storage for a period of one year, or longer, if
            requested by the employee or his representative, the Company, the
            DOT Administrator or a representative of a state agency responsible
            for ensuring Company compliance with DOT regulations.


                                       11


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

      (a)   If an employee is subject to discipline or termination under
            existing practices other than as outlined herein, such employee
            shall not utilize the Alcohol and Drug Abuse Policy to circumvent
            any labor agreements, existing practices, or to avoid discipline or
            termination.

      (b)   in the cases not covered in Section 4 (a) above, the employee will
            have the opportunity for appropriate assistance, assessment,
            referral, treatment and after-care as provided through the EAP and
            as detailed in the employee's individual treatment plan. Failure to
            seek and receive these services, or failure to abide by the terms of
            the treatment plan, shall be grounds for termination.

      (c)   Any employee who seeks and receives assistance and who completes the
            detailed treatment plan shall, upon return to work, be subject to
            periodic testing for a period of up to 60 months. The schedule for
            follow-up testing will be determined by the MRO.

      (d)   Any employee who tests positive on a follow-up test after
            rehabilitation shall be terminated in accordance with this policy.

      (e)   Any employee who successfully completes an individual treatment plan
            and who returns to work will be encouraged to contact and use the
            EAP's services on a self-referral basis whenever there is need for
            ongoing assistance and support.

      (f)   Any employee who relapses and for whom a test for reasonable cause
            of drugs or alcohol is confirmed as positive a second time, shall be
            terminated.

5.    The Employee Assistance Program shall include the following components:

      (a)   Clinical evaluation and appropriate assessment followed by a
            specific individual treatment plan and regimen for the receipt of
            counseling, treatment, aftercare and related services, subject to
            ongoing monitoring by the Company.

      (b)   Active encouragement and procedures for the voluntary self referral
            of troubled employees to the EAP in cases in which reasonable cause
            has not been established and in which testing procedures are not
            invoked.

      (c)   Assurances and procedures to protect the confidentiality of
            employees who voluntarily seek EAP services and procedures governing
            the management of such employee records as medical information.

6.    Any dispute arising with respect to drug testing shall be subject to the
      Company's complaint resolution procedure for the non-represented
      employees, or to the grievance procedure established in the current labor
      agreement for the represented employees.

POST-ACCIDENT TESTING

Post-accident testing provisions require that the same collection procedures
generally detailed above for reasonable cause testing be used when an employee's
work performance may be linked to an accident or when work performance cannot be
completely discounted as a contributing factor to an accident.

1.    The definition of an accident will be in accordance with the DOT CFR 49
      Part 191 definition of a reportable incident. Specifically: an incident
      that involves a release of gas from a pipeline or LNG facility, and

      (a)   a death, or personal injury necessitating in-patient 
            hospitalization; or
      (b)   estimated property damage, including cost of lost gas, of $50,000 or
            more, unless superseded by lower state threshold limits.

2.    An event that results in the emergency shutdown of an LNG facility.

================================================================================
                              ***Company Policy***

The use of approved personal protective equipment is mandatory when the
performance of your job duties exposes you to a workplace hazard. This policy
covers all field and retail employees and any office employee who is exposed to
potential hazards.

The protective equipment furnished by the Company will be maintained in a safe
and sanitary condition and used according to the manufacturer's recommendations.
Employees shall conduct frequent inspections of personal protective equipment to
ensure that it is in good working condition. Any equipment found to be defective
or otherwise permanently altered will be taken out of service and repaired or
replaced.

OSHA Reference: 29 CFR 1910.132, 1910.133, 1910.134, 1910.135, 1910.136,
1910.l37 and 1910.138

I.    EYE PROTECTION - Employees shall wear proper eye protection whenever
      chipping, drilling, grinding, handling acids or caustics, welding, scaling
      pipe and whenever flying objects or particulate matter may be present.
      Proper eye protection must also be used in the presence of other types of
      hazards, including fire, steam, compressed air, smoke, etc. and when
      working on piping containing gas or liquid under, or potentially under
      pressure. Eyeglasses with side shields are adequate for flying particles;
      face shields or goggles are required for chemical or splash protection.

      A.    Prescription Safety Eyewear

            i.    The Company shall provide non-prescription and prescription
                  safety eyewear to all employees whose jobs involve potential
                  eye hazards. Employees are responsible for wearing safety
                  glasses whenever their jobs involve potential eye hazards.

            ii.   New prescription safety lenses, and if necessary, frames, will
                  be provided for eligible employees when an employee's
                  corrective vision prescription warrants the change.

            iii.  The Company will purchase safety eyewear through an approved
                  safety equipment supplier selected by the Company. Procedures
                  for the purchase of prescription safety glasses will be issued
                  by the Procurement Department

                  1.    Each employee will be responsible for providing a
                        current prescription (no more than one year old) from
                        his or her optometrist or ophthalmologist at the time
                        the eyewear is ordered. The cost of eye examinations
                        will be paid by the employee.

                  2.    Only prescription safety eyewear meeting ANSI
                        requirements for industrial safety glasses will be used.


Safety & Environmental Affairs Policy Manual       Personal Protective Equipment
                                                                    Page: 1 of 5


                        Safety eye protection will be available for all
                        visitors, vendors and contractors entering eye
                        protection areas.

II.   HEARING PROTECTION - The Company shall provide hearing protection for all
      employees who may be exposed to excessive work-related noise levels.
      Employees working in excessive noise environments are required to wear the
      provided hearing protection (also see the HEARING CONSERVATION PROGRAM).

      A.    Determination of High Noise Areas

            If the supervisor or employee has questions on whether particular
            areas are subject to excessive noise levels and hearing protection
            is needed, the Safety Process Owner will survey, or will arrange to
            have surveyed, the suspect areas and advise if high noise levels
            exist.

      B.    Warning Signs

            The Company shall post warning signs in all high noise areas (areas
            where noise levels are above 85 dB time-weighted average) and shall
            supply either insert-type or muff-type hearing protectors for the
            employee's protection.

      C.    Noise Reduction Requirements

            The Noise Reduction Rating of the hearing protection provided by the
            Company must be sufficient to reduce employee exposure to an 85 dB
            time-weighted average. Guidance in the selection of hearing
            protection equipment is located in the Occupational Safety and
            Health Standards for General Industry CFR 29 1910.95, Appendix B.

III.  HAND PROTECTION - The Company shall provide hand protection for all
      employees who perform tasks that may expose their hands to harmful
      substances, severe cuts or lacerations, severe abrasions, punctures,
      chemical burns, thermal burns and harmful temperature extremes. Specialty
      gloves, such as those used for chemical, electrical or thermal protection,
      shall be approved for that particular type of hazard.

IV.   FOOT PROTECTION - Steel-toed shoes or boots are recommended in all areas
      and are required in areas where the Workplace Hazard Assessment has
      identified a danger to the feet caused by falling or rolling objects,
      piercing objects, chemical hazards, electrical exposure, etc. The Company
      will pay 50% of the cost, up to $75.00 per exposed employee per year, for
      one pair of steel-toed shoes or boots. If hazards that effect the top of
      the foot exist, additional foot guards should be used. Canvas or synthetic
      fiber cloth shoes are not appropriate footwear for employees working in
      non-office environments and are not allowed.

V.    HEAD PROTECTION - Company provided head protection shall be worn by all
      employees and contractor employees when performing work at KN field
      locations outside of the office, car or truck.

      A.    Bump caps are not acceptable head protection;

      B.    Safety helmets approved by the Department of Transportation or by
            SNELL shall be worn by all operators of All Terrain Vehicles (ATV's)
            and snow mobiles. The safety helmet shall be provided by the
            Company.

VI.   RESPIRATORY PROTECTION - (SEE RESPIRATORY PROTECTION SECTION)

VII.  FIRE RESISTANT CLOTHING - The choice of clothing for employees in the
      field is predicated on the


Safety & Environmental Affairs Policy Manual       Personal Protective Equipment
                                                                    Page: 3 of 5


      understanding of training and must be retrained as applicable.

      A.    The training provided must teach each affected employee the

Subject: CONSTRUCTION NEAR COMPANY FACILITIES
================================================================================
DAMAGE TO COMPANY             COMPANY PIPELINES AND FACILITIES BEING STRUCK,
FACILITIES                    SEVERED OR DAMAGED HAVE RESULTED IN THE NEED FOR
                              WRITTEN GUIDELINES ON THIS SUBJECT. A COMMON TIME
                              FOR SUCH INCIDENTS TO OCCUR IS DURING THE
                              INSTALLATION OF OTHER UNDERGROUND UTILITIES,
                              DURING STREET WIDENING, PAVING ROAD CONSTRUCTION,
                              OR LAND LEVELING OPERATIONS, OR THE CONSTRUCTION
                              OF HABITABLE OR AUXILIARY BUILDINGS IN CLOSE
                              PROXIMITY TO COMPANY PIPELINES.

BASIC RIGHTS                  1. The Company's basic rights in relation to its
                                 pipelines are as follows:

     o Private Property            a. The gathering system, transmission system,
                                   and distribution system are private property.
                                   If the activities of a third party threaten
                                   the safe operation of Company facilities, the
                                   Company may enjoin such persons from further
                                   action near Company property. If a pipeline
                                   or other facility is struck, Company has the
                                   right to be reimbursed for its damages.

     o Specific Privileges         b. Company has the right to fully enjoy the
                                   privileges derived from any of its easements,
                                   permits, or right-of-way grants. This
                                   includes preventing any obstructions over or
                                   near the pipeline which may interfere with
                                   maintaining, operating, repairing, replacing,
                                   or inspecting the pipe.

BASIC RESPONSIBILITIES        2. The Company's basic responsibilities in
                                 relation to its pipelines are as follows:

     o Noninterference             a. The installation of any pipelines or
                                   related facilities shall not interfere with
                                   another utility's easement. The rules
                                   regarding underground installation of other
                                   utilities must be respected by the Company
                                   just the same as the Company expects other
                                   companies to follow its own rules.
                                   Cooperation with other utility companies is
                                   essential.

     o Accurate Line Locating      b. When Company pipelines are identified by
                                   pipeline markers, stakes, or by telling a
                                   third party where the line is located, such
                                   indications must be accurate.

CONTINUING SURVEILLANCE       3. Every Company employee, whether on or off the
                              job, should be alert for forthcoming projects
                              which may endanger Company pipelines or other
                              facilities. Such projects, including the
                              construction of underground phone, electrical,
                              sewer, and water facilities, or street
                              construction projects, are often known to the
                              public long before work begins. Rural road
                              construction and land leveling are less
                              publicized; therefore, area contractors and road
                              crews should be informed of the location of
                              Company's lines and the rules regarding
                              construction activity. The public welfare and the
                              safe, uninterrupted operation of Company's
                              facilities depend upon the alertness of every
                              company employee

                                   gathering pipelines in rural areas.


CONTACT CITY OFFICIALS        18. When the construction work is within any city
                              or corporate limits, or if work is part of a city
                              project, city officials should be contacted and
                              reminded of company's rules and policies. The
                              necessary provisions regarding Company
                              requirements can then be written into an ordinance
                              or into the contract under which the work is to be
                              done.

     o Determine Damage            a. Determine extent of damage by exposing
                                   most pipe if necessary.

     o Coating Damage Only         b. Repair the pipe coating in an approved
                                   manner to insure cathodic protection if that
                                   is the only damage incurred.

     o Damaged Pipe                c. Repair or replace any damaged suction of
                                   pipe in accordance with rules outlined in
                                   Pipeline Operation and Maintenance, Section
                                   G4.0 of this manual. Damaged pipe includes
                                   dents, scratched, gouges, grooves, bends,
                                   etc. If there is any doubt about the
                                   condition of existing pipe, replace it with
                                   pretested pipe of equal or better grade and
                                   specification.

     o Loosened Connections        d. A careful examination must be made of
                                   piping in the immediate vicinity to make sure
                                   that other pipes haven't been pulled loose.
                                   For example, if a distribution main is struck
                                   and bent, it's possible that one or more
                                   nearby service stubs have been pulled loose
                                   from the meter loop connections, or a service
                                   line pulled loose from building connections.

                                        responsible for the blasting. No
                                        blasting will be permitted within 250
                                        feet of a Company pipeline unless a
                                        special written agreement is secured
                                        from the blasting contractor (see Figure
                                        1 at the end of this section). All
                                        Aboveground appurtenances will be
                                        protected from flying debris by being
                                        shielded with a protective coating:
                                        i.e., dirt, barrier, wood or metal
                                        enclosure, etc. The Operations
                                        Supervisor will confer with the blasting
                                        personnel on their proposed work and
                                        will establish with the engineering
                                        department safety requirements to
                                        protect Company facilities.

                                   d. Pipelines located within 500 feet of the
                                   blasting area will be leak-surveyed with a
                                   backpack leak detector before and after the
                                   blasting work is completed.

                                   e. Additional blasting guidelines are shown
                                   in Engineering and Construction Standards

                              permission from the engineering department.

INSPECTOR - DIGGING           12. A responsible Company employee or contract
OPERATIONS                    representative will be assigned as an inspector
                              during any digging operations which may endanger
                              or involve company pipelines or related
                              facilities. The inspector should be present as
                              necessary to prevent damage, and to detect any
                              possibility of the facilities being struck or
                              disturbed. Company will bear the cost of

INSPECTING, REPAIRING AND     15. Any Company pipelines or related facilities
BACKFILLING EXPOSED LINES     which have been exposed due to surrounding
                              construction must be thoroughly inspected. No pipe
                              can be properly inspected from the top of a ditch;
                              the employee assigned to inspect the line must
                              check all exposed areas of the pipe closely, and
                              be alert for signs of damage even beyond the
                              exposed portion, such as excess movement of the
                              pipe from its installed position. If a pipe has
                              been struck:


     o Review by Engineering       d. The Engineering Department will review the
       Department                  information forwarded by the inspector and

                                   and what portion is to be paid by Company.
                                   The Engineering Department will then provide
                                   details of the modification required and the
                                   costs involved, and will advise what
                                   agreements, if any, will be necessary between
                                   Company and the landowner before commencement
                                   of the project.

     o Attempt to Modify           e. Company will attempt to begin the required

       Alternatives                land or making the improvements so as to
                                   avoid relocation of the Company pipeline, or
                                   to avoid removal of soil over a buried line.
                                   If the landowner can achieve substantially
                                   the desired results without jeopardizing or
                                   disturbing the Company pipeline, this is what
                                   he should do.

     o Pipeline Relocation         c. If the leveling or improvement cannot be
       or Modification             accomplished without relocation or         
       Required                    modification of the Company pipeline, the  
                                   Company representative shall gather pertinent

                                   ARTICLE III
                               AUTHORIZED CAPITAL

        A. Common Stock

        The Corporation shall have authority to issue Five Million (5,000,000)
shares of voting common stock, all of the same class and having a par value of
one cent ($0.01) per share. The term "Common Stock" as used herein means the
voting common stock as the same exists at the effective date of this Restated
Certificate of Incorporation or any other class of stock resulting from
successive changes or reclassifications of such voting common stock consisting
solely of chances in par value, or from par value to no par value, or from no
par value to par value.

      B. Preferred Stock

      Section 1 (a) The Corporation shall have authority to issue Two Million
Six Hundred Fifty One Thousand Forty Six (2,651,046) shares of preferred stock
having a par value of one cent ($0.01) per share, of which One Million
(1,000,000) shares shall be designated Series A Convertible Preferred Stock (the
"Series A Preferred Stock") and One Million Six Hundred Fifty One Thousand Forty
Six (1,651,046) shares shall be designated Series B Convertible Preferred Stock
(the "Series B Preferred Stock"). The Series A Preferred Stock and the Series B
Preferred Stock shall be referred to collectively herein as the "Series
Preferred Stock".

                (b) Dividends, The holders of the Series Preferred Stock shall
be entitled to receive, out of funds legally available therefor, dividends
(other than dividends paid in additional shares of Common Stock) in preference
to and at the same rate as dividends are paid with respect to the Common Stock
(treating each share of Series Preferred Stock as being equal to the number of
shares of Common Stock into which each such share of Series Preferred Stock
could be converted pursuant to the provisions of Section 4 hereof, with such
number determined as of the record date for the determination of holders of
Common Stock entitled to receive such dividend).

      Section 2     Liquidation Dissolution or Winding Up

                (a) Distributions to Holders of Preferred Stock. In the event of
any liquidation, dissolution or winding up of the Corporation, whether voluntary
or involuntary, the Series A Preferred Stock and the Series B Preferred Stock
shall rank on a parity with each other and shall rank prior to the Common Stock
or any class of stock ranking junior to the Series


                                       2


Preferred Stock. Upon such liquidation, holders of each share of Series
Preferred Stock outstanding shall be entitled to be paid, out of the assets of
the Corporation available for distribution to stockholders and before any
payment shall be made to the holders of any class of Common Stock or of any
stock ranking on liquidation junior to the Series Preferred Stock, an amount in
cash equal to the original purchase price paid by such holder for each such
share of Series Preferred Stock held (appropriately adjusted for stock splits,
stock dividends and the like) plus any declared but unpaid dividends thereon. If
upon any liquidation, dissolution, or winding up of the Corporation, the assets
to be distributed to the holders of the Series Preferred Stock under the
foregoing sentence shall be insufficient to permit payment to such stockholders
of the full preferential amounts aforesaid, then all of the assets of the
Corporation available for distribution to such holders under such sentence shall
be distributed among the holders of Series Preferred Stock, pro rata in
accordance with the total amount of preference which would have been payable to
such holders if funds had been available to pay the full preference under the
previous sentence. After such payment shall have been made in full to such
holders of Series Preferred Stock, or funds necessary for such payment shall
have been set aside by the Corporation in trust for the account of such holders
so as to be available for such payment, the holders of the outstanding shares of
Common Stock shall share ratably in the distribution of the remaining assets and
funds of the Corporation available for distribution to shareholders.

                (b) Deemed Liquidations. In the case of (i) a consolidation or
merger of the Corporation (other than a consolidation or merger upon
consummation of which the holders of voting securities of the Corporation
immediately prior to such transaction, continue to own directly or indirectly
not less than a majority of the voting power of the surviving corporation) or a
sale of all or substantially all of the assets of the Corporation or other
similar transaction and (ii) either receipt by the Corporation of consideration
less than the equivalent of $1.00 per share (appropriately adjusted for stock
splits, stock dividends and the like) of Series A Preferred Stock plus any
declared but unpaid dividends or receipt by the Corporation of consideration
less than the equivalent of $3.28 per share (appropriately adjusted for stock
splits, stock dividends and the like) of Series B Preferred Stock plus any
declared but unpaid dividends, such event shall be regarded, at the option of
the holders of a majority of the then outstanding shares of Series Preferred
Stock as a liquidation, dissolution or winding up of the affairs of the
Corporation within the meaning of this Section 2.

      Notwithstanding the foregoing, each holder of Series Preferred Stock shall
have the right to elect the benefits of the provisions of Section 4(h) hereof in
lieu of receiving payment in liquidation, dissolution or winding up of the
Corporation pursuant to this Section 2(b). For purposes of this Section 2 and
Section 6 hereof, a sale of substantially all of the assets of the Corporation
shall mean (x) the sale or other disposition other than in the ordinary course
of business of more than 50% of such assets, as determined by reference to
either (A) the book value, or (B) the fair market value, of such assets, or (y)
any issuance of Common Stock by the Corporation or transfer of Common Stock by
the holder thereof to any person or persons acting in concert or a group of
affiliated persons, which issuance or transfer results in such person or persons
or group holding in the aggregate more than 50% of the issued and outstanding
Common Stock after giving effect to such issuance or transfer


                                       3


                (c) Non-Cash Distributions. In the event of a liquidation,
dissolution or winding up of the Corporation resulting in the availability of
assets other than cash for distribution to the holders of the Series Preferred
Stock, the holders of the Series Preferred Stock shall be entitled to a
distribution of cash and/or assets equal in value to the liquidation preference
and other distribution rights stated in Sections 2(a) and 2(b) hereof. In the
event that such distribution to the holders of the Series Preferred Stock shall
include any assets other than cash, the following provisions shall govern. The
Board of Directors shall first determine the value of such assets for such
purpose, and shall notify all holders of shares of Series Preferred Stock of
such determination. The value of such assets for purposes of the distribution
under this Section 2(c) shall be the value as determined by the Board of
Directors in good faith and with due care, unless the holders of a majority of
the outstanding shares of Series Preferred Stock shall object thereto in writing
within 15 days after the date of such notice. In the event of such objection,
the valuation of such assets for purposes of such distribution shall be
determined by an arbitrator selected by the objecting stockholders and the Board
of Directors, or in the event a single arbitrator cannot be agreed upon within
10 days after the written objection sent by the objecting stockholders in
accordance with the previous sentence, the valuation of such assets shall be
determined by arbitration in which (i) the objecting stockholders shall name in
their notice of objection one arbitrator, (ii) the Board of Directors shall name
a second arbitrator within 15 days from the receipt of such notice, (iii) the
two arbitrators thus selected shall select a third arbitrator within 15 days
thereafter, and (iv) the three arbitrators thus selected shall determine the
valuation of such assets within 15 days thereafter for purposes of such
distribution by majority vote. The costs of such arbitration shall be borne by
the Corporation or by the holders of the Series Preferred Stock (on a pro rata
basis out of the assets otherwise distributable to them) as follows: (i) if the
valuation as determined by the arbitrators is greater than 95 % of the valuation
as determined by the Board of Directors, the holders of the Series Preferred
Stock shall pay the costs of the arbitration, and (ii) otherwise, the
Corporation shall bear the costs of the arbitration.

      Section 3     Voting Rights

                (a) General. Except as otherwise expressly provided herein or as
required by law, the holder of each share of the Series Preferred Stock shall be
entitled to vote on all matters. Each share of Series Preferred Stock shall
entitle the holder thereof to such number of votes per share as shall equal the
number of shares of Common Stock into which such share of Series Preferred Stock
is convertible in accordance with the terms of Section 4 hereof at the record
date for the determination of stockholders entitled to vote on such matter or,
if no record date is established, at the date such vote is taken or any written
consent of stockholders is solicited. Except as otherwise expressly provided
herein (including, without limitation, the provisions of Section 5 hereof) or as
required by law, the holders of shares of Series Preferred Stock and the Common
Stock shall vote together as a single class on all matters.

                (b) Board of Directors. The holders of the Series A Preferred
Stock shall be entitled to vote as a class separately from all other classes of
stock of the Corporation in any vote for the election of directors of the

                                       4


shares of Series A Preferred Stock and thereafter by the holders of a majority
of the issued and outstanding shares of Series A Preferred Stock, and the other

affiliates (collectively, "NEA VI") for so long as it owns shares of Series A
Preferred Stock and thereafter by the holders of a majority of the issued and
outstanding shares of Series A Preferred Stock. The holders of the Series B

majority of the Series A Investor Directors and Series B Investor Director,

Directors. shall be elected to the Corporation's Board of Directors by the
holders of the Series Preferred Stock and the Common Stock voting together as a
single class. In addition, a Chief Executive Officer of the Corporation (and any
successor thereto) shall be selected and hired by the Corporation, at all times
prior to December 23, 2000, by the affirmative vote of at least four of the five
Common Stock Directors, Series A investor Directors and the Series B Investor
Director, voting together, provided however, that (i) on or after December 23,

majority of the Common Stock Directors, the Series A Investor Directors and the
Series B Investor Director, voting together, shall select and hire a Chief
Executive Officer (or any successor thereto) as such. The Chief Executive
Officer as so selected and hired (and any replacement or successor Chief
Executive Officer) shall be elected to the Corporation's Board of Directors by
the holders of the Series Preferred Stock and the Common Stock voting together
as single class (the "Officer Director"). David Schaeffer may serve as Chief
Executive Officer of the Corporation in the discretion of the Board of
Directors, but in no event shall David Schaeffer be elected as the Officer
Director.

                (c) Special Voting Rights. The holders of the Series Preferred
Stock shall be entitled to the special voting rights set forth in Section 6
hereof.

      Section 4     Conversion. The holders of the Series Preferred Stock shall
have the following conversion rights:


                                       5


                (a) Right to Convert. Subject to and in compliance with the
provisions of this Section 4, any shares of the Series Preferred Stock may, at
any time or from time to time at the option of the holder, be convened into
fully-paid and non-assessable shares of Common Stock. The number of shares of
Common Stock to which a holder of the Series Preferred Stock shall be entitled
upon conversion shall be the product obtained by multiplying the Applicable
Conversion Rate (determined as provided in Section 4(c)) by the number of shares
of Series Preferred Stock being converted.

                (b) Automatic Conversion.

                    (i) Each share of the Series Preferred Stock outstanding
shall automatically be converted into the number of shares of Common Stock into
which such shares are convertible upon application of the then effective
Applicable Conversion Rate (determined as provided in Section 4(c)) immediately
upon the closing of an underwritten public offering pursuant to an effective
registration statement under the Securities Act of 1933, as amended, or under
such other applicable securities regulations covering the offer and sale of
capital stock of the Corporation (other than a registration relating solely to
Rule 145 under such Act (or any successor thereto) or to an employee benefit
plan of the Corporation) in which (i) the Corporation is valued on a pre-money
basis at greater than $50,000,000, (ii) the gross proceeds received by the
Corporation exceed $20,000,000 and (iii) the Corporation uses a nationally
recognized underwriter approved by holders of a majority in interest of the
Series Preferred Stock (a "Qualified Public Offering").

                    (ii) Upon the occurrence of an event specified in Section
(4)(b)(i), the outstanding shares of Series Preferred Stock shall be convened
automatically without any further action by the holders of such shares and
whether or not the certificates representing such shares are surrendered to the
Corporation or its transfer agent; provided, however, that the Corporation shall
not be obligated to issue certificates evidencing such shares of the Series
Preferred Stock unless certificates evidencing such shares of the Series
Preferred Stock being convened are either delivered to the Corporation or any
transfer agent, as hereinafter provided, or the holder notifies the Corporation
or any transfer agent, as hereinafter provided, that such certificates have been
lost, stolen or destroyed and executes an agreement satisfactory to the
Corporation to indemnify the Corporation from any loss incurred by it in
connection therewith.

      Upon the occurrence of the automatic conversion of all of the outstanding
Series Preferred Stock, the holders of the Series Preferred Stock shall
surrender the certificates representing such shares at the office of the
Corporation or of any transfer agent for the Common Stock. Thereupon there shall
be issued and delivered to each such holder, promptly at such office and in his
name as shown on such surrendered certificate or certificates, a certificate or
certificates for the number of shares of Common Stock into which the shares of
the Series Preferred Stock surrendered were convertible on the date on which
such automatic conversion occurred and cash as provided in Section 4(k) below
in respect of any fraction of a share of Common Stock issuable upon such
automatic conversion.


                                       6


                (c) Applicable Conversion Rate. The conversion rate in effect at
any time for the applicable series of Series Preferred Stock (the "Applicable
Conversion Rate") shall equal the quotient obtained by dividing $1.00 in the
case of Series A Preferred Stock, or $3.28 in the case of Series B Preferred
Stock by the Applicable Conversion Value, calculated as hereinafter provided.

                (d) Applicable Conversion Value. The Applicable Conversion Value
in effect initially, and until first adjusted in accordance with Section 4(e) or
4(f) hereof, shall be $1.00 in the case of Series A Preferred Stock, or $3.28 in
the case of Series B Preferred Stock.

                (e) Adjustment for Common Stock Dividends, Subdividends and
Combinations of Common Stock, Etc. Upon the happening of any of the following:
(i) the issuance of additional shares of Common Stock of any class as a dividend
or other distribution of outstanding Common Stock, (ii) the subdivision of 
outstanding shares of Common Stock of any class into a greater number of shares
of Common Stock, or (iii) the combination of outstanding shares of Common Stock
of any class into a smaller number of shares of Common Stock (each an
"Extraordinary Common Stock Event"), the Applicable Conversion Value shall,
simultaneously with the happening of such Extraordinary Common Stock Event, be
adjusted by dividing the then effective Applicable Conversion Value by a
fraction, the numerator of which shall be the number of shares of Common Stock
outstanding (excluding treasury stock) immediately after such Extraordinary
Common Stock Event and the denominator of which shall be the number of shares of
Common Stock outstanding (excluding treasury stock) immediately prior to such
Extraordinary Common Stock Event, and the quotient so obtained shall thereafter
be the Applicable Conversion Value. The Applicable Conversion Value, as so
adjusted, shall be readjusted in the same manner upon the happening of any
successive Extraordinary Common Stock Event or Events.

                (f) Adjustments for Diluting Issues

                    (i) Except as provided in Section 4(e) above or for Excluded
Shares (as defined below), if the Corporation shall issue any additional shares
of Common Stock of any class for no consideration or at a price per share less
than the Applicable Conversion Value in effect for each applicable series of
Series Preferred Stock immediately prior to such issuance or sale, then in each
such case such Applicable Conversion Value shall be reduced to such lower price.

      For purposes of this Section 4(f), "Excluded Shares" shall mean shares
issued or delivered from treasury or stock options granted by the Corporation,
with the approval of the Board of Directors to directors, officers, employees,
agents or consultants of the Corporation (other than David Schaeffer) for up to
an aggregate of 439,024 shares of the Common Stock (as adjusted for stock
splits, stock dividends and the like).

      For purposes of this Section 4(f), if a part or all of the consideration
received by the Corporation in connection with the issuance of shares of the
Common Stock or the issuance of any of the securities described below in
paragraph (ii) of this Section 4(f) consists of property other than cash, such
consideration shall be deemed to have the same value as is determined by the


                                       7


Corporation's Board of Directors with respect to receipt of such property so
long as such determination was made reasonably and in good faith, and shall
otherwise be deemed to have a value equal to its fair market value.

                    (ii) For the purpose of this Section 4(f), the issuance of
any warrants, options or other subscription or purchase rights with respect to
shares of Common Stock of any class and the issuance of any securities
convertible into shares of Common Stock of any class (or the issuance of any
warrants, options or any rights with respect to such convertible securities)
shall be deemed an issuance at such time of such Common Stock if the Net
Consideration Per Share which may be received by the Corporation for such Common
Stock (as hereinafter determined) shall be less than the Applicable Conversion
Value at the time of such issuance and, except as hereinafter provided, an
adjustment in the Applicable Conversion Value shall be made upon each such
issuance in the manner provided in paragraph (i) of this Section 4(f) as if such
Common Stock were issued at such Net Consideration Per Share. No adjustment of
the Applicable Conversion Value shall be made under this Section 4(f) upon the
issuance of any additional shares of Common Stock which are issued pursuant to
the exercise of any warrants, options or other subscription or purchase rights
or pursuant to the exercise of any conversion or exchange rights in any
convertible securities if any adjustment shall previously have been made upon
the issuance of such warrants, options or other rights. Any adjustment of the
Applicable Conversion Value with respect to this paragraph (ii) of this Section
4(f) shall be disregarded if, as and when the rights to acquire shares of Common
Stock upon exercise or conversion of the warrants, options, rights or
convertible securities which gave rise to such adjustment expire or are canceled
without having been exercised, so that the Applicable Conversion Value effective
immediately upon such cancellation or expiration shall be equal to the
Applicable Conversion Value in effect immediately prior to the time of the
issuance of the expired or canceled warrants, options, rights or convertible
securities, with such additional adjustments as would have been made to that
Applicable Conversion Value had the expired or canceled warrants, options,
rights or convertible securities not been issued, provided, however, that no
such readjustment of the Applicable Conversion Value shall have the effect of
increasing the Applicable Conversion Value to an amount which exceeds the lower
of (I) the Applicable Conversion Value on the original adjustment date, or (II)
the Applicable Conversion Value that would have resulted from any issuance of
any additional shares of Common Stock pursuant to such warrants, options, rights
or convertible securities between the original adjustment date and such
readjustment date. In the event that the terms of any warrants, options, other
subscription or purchase rights or convertible securities previously issued by
the Corporation are changed (whether by their terms or for any other reason) so
as to change the Net Consideration Per Share payable with respect thereto
(whether or not the issuance of such warrants, options, rights or convertible
securities originally gave rise to an adjustment of the Applicable Conversion
Value), the Applicable Conversion Value shall be recomputed as of the date of
such change, so that the Applicable Conversion Value effective immediately upon
such change shall be equal to the Applicable Conversion Value in effect at the
time of the issuance of the warrants, options, rights or convertible securities
subject to such change, adjusted for the issuance thereof in accordance with the
terms thereof after giving effect to such change, and with such additional
adjustments as would have been made to that Applicable Conversion Value had the
warrants, options, rights or convertible securities been issued on such changed
terms. For purposes


                                       8


of this paragraph (ii), the Net Consideration Per Share which may be received by
the Corporation shall be determined as follows:

                         (A) The Net Consideration Per Share shall mean the
amount equal to the total amount of consideration, if any, received by the
Corporation for the issuance of such warrants, options, rights or convertible
securities, plus the minimum amount of consideration, if any, payable to the
Corporation upon exercise or conversion thereof, divided by the aggregate number
of shares of Common Stock that would be issued if all such warrants, options,
subscriptions, or other purchase rights or convertible securities were exercised
or converted at such net consideration per share.

                         (B) The Net Consideration Per Share which may be
received by the Corporation shall be determined in each instance as of the date
of issuance of warrants, options, rights or convertible securities without
giving effect to any possible future price adjustments or rate adjustments which
may be applicable with respect to such warrants, options, rights or convertible
securities and which are contingent upon future events, provided that in the
case of an adjustment to be made as a result of a change in terms of such
warrants, options, rights or convertible securities, the Net Consideration Per
Share shall be determined as of the date of such change.

                    (g) Adjustments for Reclassification. If the Common Stock
issuable upon the conversion of the Series Preferred Stock shall be changed into
the same or different number of shares of any class or classes of stock, whether
by reclassification or otherwise (other than an Extraordinary Common Stock
Event, or a reorganization, merger, consolidation or sale of assets provided for
elsewhere in this Section 4), then and in each such event the holder of each
share of Series Preferred Stock shall have the right thereafter to convert such
share into the kind and amount of shares of stock and other securities and
property receivable upon such reorganization, reclassification or other change
by holders of the number of shares of Common Stock into which such shares of
Series Preferred Stock might have been convened immediately prior to such
reorganization, reclassification or change, all subject to further adjustment as
provided herein. Without limiting the generality of the foregoing, the 
Applicable Conversion Rate, as defined in this Section 4, in respect of such 
other shares or securities so receivable upon conversion of shares of Series 
Preferred Stock shall thereafter be adjusted, and shall be subject to further 
adjustment from time to time, in a manner and on terms as nearly equivalent as 
practicable to the provisions with respect to Common Stock contained in this 
Section 4, and the remaining provisions herein with respect to the Common Stock 
shall apply on like or similar terms to any such other shares or securities.

                  (h) Adjustments for Reorganizations. If at any time or from
time to time there shall be a capital reorganization of the Common Stock (other
than a subdivision, combination, reclassification or exchange of shares provided
for elsewhere in this Section 4) or a merger or consolidation of the Corporation
with or into another corporation or the sale of all or substantially all of the
Corporation's properties and assets to any other person, then, as a part of and
as a condition to the effectiveness of such reorganization, merger,
consolidation or sale, lawful and adequate provision shall be made so that if
the Corporation is not the surviving


                                       9


corporation, the Series Preferred Stock shall be convened into preferred stock
of the surviving corporation having equivalent preferences, rights and
privileges except that in lieu of being able to convert into shares of Common
Stock of the Corporation or the successor corporation the holders of the Series
Preferred Stock (including any such preferred stock issued upon conversion of
the Series Preferred Stock) shall thereafter be entitled to receive upon
conversion of the Series Preferred Stock (including any such preferred stock
issued upon conversion of the Series Preferred Stock) the number of shares of
stock or other securities or property of the Corporation or of the successor
corporation resulting from such merger or consolidation or sale, to which a
holder of the number of shares of Common Stock deliverable upon conversion of
the Series Preferred Stock immediately prior to the capital reorganization,
merger, consolidation or sale would have been entitled on such capital
reorganization, merger, consolidation, or sale. In any such case, appropriate
provisions shall be made with respect to the rights of the holders of the Series
Preferred Stock (including any such preferred stock issued upon conversion of
the Series Preferred Stock) after the reorganization, merger, consolidation or
sale to the end that the provisions of this Section 4 (including, without
limitation, provisions for adjustment of the Applicable Conversion Value and the
number of shares purchasable upon conversion of the Series Preferred Stock or
such preferred stock) shall thereafter be applicable, as nearly as may be, with
respect to any shares of stock, securities or assets to be deliverable
thereafter upon the consideration of the Series Preferred Stock or such
preferred stock.

      Each holder of Series Preferred Stock upon the occurrence of a capital
reorganization, merger or consolidation of the Corporation or the sale of all or
substantially all of its assets and properties as such events are more fully set
forth in the first paragraph of this Section 4(h), shall have the option of
electing treatment of his shares of Series Preferred Stock under either this
Section 4(h) or Section 2(b) hereof, and except as otherwise provided in said
Section 2(b), notice of which election shall be submitted in writing to the
Corporation at its principal offices no later than 10 days before the effective
date of such event, provided that any such notice shall be effective if given
not later than 15 days after the date of the Corporation's notice, pursuant to
Section 8, with respect to such event.

                    (i) Certificate as to Adjustments. In each case of an
adjustment or readjustment of the Applicable Conversion Rate, the Corporation
will promptly furnish each holder of Series Preferred Stock with a certificate,
prepared by the chief financial officer of the Corporation, showing such
adjustment or readjustment, and stating in detail the facts upon which such
adjustment or readjustment is based.

                    (j) Mechanics of Conversion. To exercise its conversion
privilege, a holder of Series Preferred Stock shall surrender the certificate or
certificates representing the shares being converted to the Corporation at its
principal office, and shall give written notice to the Corporation at that
office that such holder elects to convert such shares. Such notice shall also
state the name or names (with address or addresses) in which the certificate or
certificates for shares of Common Stock issuable upon such conversion shall be
issued. The certificate or certificates for shares of Series Preferred Stock
surrendered for conversion shall be accompanied by proper assignment thereof to
the Corporation or in blank. The date when such written notice is received by
the Corporation together with the certificate or certificates representing the
shares of


                                       10


Series Preferred Stock being converted, shall be the "Conversion Date". As
promptly as practicable after the Conversion Date, the Corporation shall issue
and shall deliver to the holder of the shares of Series Preferred Stock being
convened, a certificate or certificates in such denominations as it may request
in writing for the number of full shares of Common Stock issuable upon the
conversion of such shares of Series Preferred Stock in accordance with the
provisions of this Section 4 and cash as provided in Section 4(k) below in
respect of any fraction of a share of Common Stock issuable upon such
conversion. Such conversion shall be deemed to have been effected immediately
prior to the close of business on the Conversion Date, and at such time the
rights of the holder as holder of the converted shares of Series Preferred Stock
shall cease and the person or persons in whose name or names any certificate or
certificates for shares of Common Stock shall be issuable upon such conversion
shall be deemed to have become the holder or holders of record of shares of
Common Stock represented thereby.

                (k) Fractional Shares. No fractional shares of Common Stock or
scrip representing fractional shares shall be issued upon conversion of Series
Preferred Stock. Instead of any fractional shares of Common Stock that would
otherwise be issuable upon conversion of Series Preferred Stock, the Corporation
shall pay to the holder of the shares of Series Preferred Stock that were
converted a cash adjustment in respect of such fraction in an amount equal to
the same fraction of the market price per share of the Common Stock (as
determined in a manner prescribed in good faith by the Board of Directors) at
the close of business on the Conversion Date.

                (l) Partial Conversion. In the event some but not all of the
shares of Series Preferred Stock represented by a certificate or certificates
surrendered by a holder are converted, the Corporation shall execute and deliver
to or on the order of the holder, at the expense of the Corporation, a new
certificate representing the number of shares of Series Preferred Stock which
were not converted.

                (m) Reservation of Common Stock. The Corporation shall at all
times reserve and keep available out of its authorized but unissued shares of
Common Stock, solely for the purpose of effecting the conversion of the shares
of the Series Preferred Stock, such number of its shares of Common Stock as
shall from time to time be sufficient to effect the conversion of all
outstanding shares of the Series Preferred Stack, and if at any time the number
of authorized but unissued shares of Common Stock shall not be sufficient to
effect the conversion of all then outstanding shares of the Series Preferred
Stock, the Corporation shall take such corporate action as may, in the opinion
of its counsel, be necessary to increase its authorized but unissued shares of
Common Stock to such number of shares as shall be sufficient for such purpose.


      Section 5     Redemption

                (a) Optional Redemption. In the event that there shall not have
occurred a dosing of a Qualified Public Offering (as defined in Section 4(b)
hereof) prior to December 23, 2000, at the election of each holder of the Series
Preferred Stock outstanding as of December 24, 2000, the Corporation shall
redeem all shares of the Series Preferred Stock then outstanding. Payment of the
applicable Redemption Price (as defined below) shall be made by the Corporation
on January 23, 2001, for a cash price equal to the original purchase price paid
by


                                       11


such holders for each share of Series Preferred Stock outstanding, adjusted for
any stock split, combined consolidation or stock distribution or stock dividends
with respect to such shares (the "Redemption Price"). On or prior to December
24, 2000, the Corporation shall give written notice by mail, postage prepaid, to
the holders of the then outstanding shares of the Series Preferred Stock at the
address of each such holder appearing on the books of the Corporation or given
by such holder to the Corporation for the purpose of notice. Such notice shall
set forth the Redemption Price as defined above) and shall further state that
any holder of the Series Preferred Stock who intends to request redemption of
its Series Preferred Stock pursuant to this Section 5(a) must give written
notice to the Corporation of its request for redemption on or before January 11,
2001. If the Corporation receives requests for redemption on or prior to January
11, 2001 from the holders of a majority of the Series Preferred Stock, it shall
give written notice by mail, postage prepaid, to the holders of Series Preferred
Stock that all shares of the Series Preferred Stock then outstanding will be
redeemed on January 23, 2001 (the "Redemption Date") for a per share cash price
equal to the Redemption Price. The notice shall further call upon such holders
to surrender to the Corporation on or before the Redemption Date at the place
designated in the notice such holder's certificate or certificates representing
the shares to be redeemed. On or after the Redemption Date, each holder of 
shares of the Series Preferred Stock called for redemption shall surrender the
certificate evidencing such shares to the Corporation. In the case of any
certificate or certificates which have been lost, stolen or destroyed, the
holder of such certificate or certificate shall make and deliver an affidavit of
that fact to the Corporation without the necessity of giving the Corporation a
bond.

                (b) Termination of Rights. From and after the Redemption Date,
unless there shall have been a default in payment or tender by the Corporation
of the Redemption Price, all rights of the holders with respect to such redeemed
shares of the Series Preferred Stock (except the right to receive the Redemption
Price upon surrender or their certificate) shall cease and such shares shall not
thereafter be transferred on the books of this Corporation or be deemed to be
outstanding for any purpose whatsoever.

                (c) Insufficient Funds. If the funds of the Corporation legally
available for redemption of shares of the Series Preferred Stock on the
Redemption Date are insufficient to redeem the total number of shares of the
Series Preferred Stock on such Redemption Date, the Corporation will use its
best efforts to engage in a recapitalization or the sale of its business or
businesses to generate sufficient funds to redeem all of the shares of Series
Preferred Stock. The Corporation shall use those funds which are legally
available to redeem the maximum possible number of such shares ratably among the
holders of such shares to be redeemed. At any time thereafter when additional
funds of the Corporation are legally available for the redemption of shares of
the Series Preferred Stock, such funds will immediately be used to redeem the
balance of the shares which the Corporation has become obligated to redeem on
the Redemption Date but which it has not redeemed at the Redemption Price. If
any shares of the Series Preferred Stock are not redeemed for the foregoing
reason or because the Corporation otherwise failed to pay or tender to pay the
aggregate Redemption Price on all outstanding shares of Series Preferred Stock,
all shares which have not been redeemed shall remain outstanding and entitled to
all the rights and preferences provided herein, and the Corporation shall pay
interest on the Redemption Price for the unredeemed portion at an aggregate per
annum rate equal to the greater of (i) twelve percent


                                       12


(12%) or (ii) the Base Rate or any similar lending rate announced from time to
time by The First National Bank of Boston or any successor entity plus five
percent (5%), increased, in each case, by one percent (1%) at the end of each
calendar quarter thereafter. All provisions hereof are hereby expressly limited
so that in no contingency or event whatsoever shall the amount paid or agreed to
be paid to the holders of the Series Preferred Stock exceed the maximum amount
which the holder is permitted to receive under applicable law. If fulfillment of
any provision hereof shall involve exceeding such amount, then the obligation to
be fulfilled shall automatically be reduced to the limit of such maximum amount.
As used herein, the term "applicable law" shall mean the law in effect as of the
date hereof, provided, however, that in the event that there is a change in the
law, which results in a higher permissible rate of interest, then these
provisions shall be governed by such new law as of its effective date.

      Section 6     Restrictions and Limitations. The Corporation shall not
without the affirmative vote or written consent of the holders of a majority of
the then outstanding shares of the Series Preferred Stock:

                (i) Redeem, purchase or otherwise acquire for value (or pay into
or set aside for a sinking fund for such purpose), any share or shares of Series
Preferred Stock other than pursuant to Section 5 hereof;

                (ii) Redeem, purchase or otherwise acquire for value (or pay
into or set aside for a sinking fund for such purpose) any of the Common Stock
of any class or any other capital stock of the Corporation other than the Series
Preferred Stock or any of the Corporation's options, warrants or convertible or
exchangeable securities, except that these provisions will not prohibit the
Corporation from repurchasing or redeeming any shares of capital stock from
individuals and entities who have entered into stockholder agreements under
which the Corporation has the option to repurchase such shares upon the
occurrence of certain events, including the termination of employment and
involuntary transfers by operation of law (and their permitted transferees)
provided that the aggregate amount of repurchases thereunder shall not exceed
$50,000;

                (iii) Authorize or issue, or obligate itself to Issue, any other
debt or equity security, other than as provided in that certain Investment and
Stockholder's Agreement, by and among the Corporation and the Investors named
therein, dated as of December 23, 1996 (the "Investment Agreement");

                (iv) Increase or decrease (other than by conversion as permitted
hereby) the total number of authorized shares of Series Preferred Stock;

                (v) Pay or declare any dividend or distribution on any of its
capital stock;

                (vi) Authorize any merger, consolidation of the Corporation with
or into any other company or entity, or authorize the reorganization or sale of
the Corporation or the sale of substantially all of the assets of the
Corporation;


                                       13


                (vii) Amend the charter documents of the Corporation or amend
the bylaws of the Corporation in any manner that adversely affects the
preferences, powers, rights or privileges of the holders of Series Preferred
Stock;

                (viii) Authorize any reclassification or recapitalization of the
outstanding capital stock of the Corporation;

                (ix) Approve the annual operating budget of the Corporation;

                (x) Change the composition or compensation of management, or

                (xi) Incur, create, assume, become or be liable in any manner
with respect to, or permit to exist, any new or additional indebtedness or
liability in excess of $50,000, except as provided in the Investment Agreement.

      Section 7     No Reissuance of Series Preferred Stock. No share or shares
of the Series Preferred Stock acquired by the Corporation by reason of
redemption, purchase, conversion or otherwise shall be reissued, and all such
shares shall be canceled, retired, and eliminated from the shares which the
Corporation shall be authorized to issue. The Corporation may from time to time
take such appropriate corporate action as may be necessary to reduce the
authorized number of shares of the Series Preferred Stock accordingly.

      Section 8     Notices of Record Date. In the event (i) the Corporation
establishes a record date to determine the holders of any class of securities
who are entitled to receive any dividend or other distribution, or (ii) there
occurs any capital reorganization of the Corporation, any reclassification or
recapitalization of the capital stock of the Corporation, any merger or
consolidation of the Corporation, or any transfer of all or substantially all of
the assets of the Corporation to any other company, or any other entity or
person, or any voluntary or involuntary dissolution, liquidation or winding up
of the Corporation, the Corporation shall mail to each holder at Series
Preferred Stock at least 20 days prior to the record date specified therein, a
notice specifying (a) the date of such record date for the purpose of such
dividend or distribution and a description of such dividend or distribution, (b)
the date on which any such reorganization, reclassification, transfer,
consolidation, merger, dissolution, liquidation or winding up is expected to
become effective, and (c) the time, if any, that is to be fixed, as to when the
holders of record or Common Stock (or other securities) shall be entitled to
exchange their shares of Common Stock (or other securities) for securities or
other property deliverable upon such reorganization, reclassification, transfer,
consolidation, merger. dissolution, liquidation or winding up.

      Section 9     Other Rights. Except as otherwise provided in this Restated
Certificate of Incorporation shares of each series of the Series Preferred Stock
and shares of Common Stock shall be identical in all respects (each share of
Series Preferred Stock having equivalent rights to the number of shares of
Common Stock into which it is then convertible), shall have the same powers,
preferences and rights, without preference of any such class or share over any
other such class or share, and shall be treated as a single class of stock for
all purposes.


                                       14


      Section 10    Ranking. The Series B Preferred Stock shall rank on a parity
with the Series A Preferred Stock as to the distribution of assets on
liquidation, dissolution and winding up of the Corporation. The Series Preferred
Stock shall rank senior to the Common Stock as to the distribution of assets on

                  laws affecting creditors' rights generally, (ii) equitable

notice of any extensions granted, collateral received or delivered or any action
taken in reliance hereon; all demands and notices in connection with the

litigated under the laws of the State of New York and agrees to be subject to
the jurisdiction of the Courts of the State of New York or (in a case involving

thereof, and (c) within forty-five (45) days after summons and complaint, and
should the Pledgor so served fail to appear or answer within said forty-five
(45) day period, the Pledgor shall be deemed in default and judgment entered
against the Pledgor for the amount demarked in any summons and complaint so
served.

      8. Succession. This Agreement shall be binding upon and inure to the

shall neither limit nor enlarge the provisions hereof.

      15. FCC Consent. Notwithstanding anything to the contrary contained herein
or the FPM Agreement, the Pledgee will not take any action pursuant to this
Agreement or the FPM Agreement that would constitute or result in any assignment
of or a transfer of control of any FCC authorization(s) held by Pledgor if such
assignment or transfer of control would require under then existing law
(including the written rules and regulations promulgated by the FCC), the prior
approval of the FCC, without first obtaining such approval of the FCC. The
Pledgee specifically agrees that (a) the voting rights of the pledged assets
will remain with the Pledgor upon and following the occurrence of an Event of
Default unless any required prior approvals of the FCC to the transfer of such
voting rights to the Pledgee shall have been obtained; and (b) prior to the
exercise of voting rights by the purchaser at any such sale, the prior consent
of the FCC pursuant to 47 U.S.C. 310(d) will be obtained. The Pledgor agrees to
take any action which the Pledgee may reasonably request in order to obtain and
enjoy the full rights and benefits granted to the Pledgee by this Agreement
including specifically the use of the best efforts of the Pledgor to assist in
obtaining approval of the FCC for any action or transaction contemplated by this
Agreement which is then required by law, and specifically, without limitation,
upon request following the occurrence of an Event of Default, to prepare, sign
and file (or cause to be prepared, signed or filed) with the FCC any portion of
any application or applications for consent to the assignment of an
authorization or transfer of control required to be signed by the Pledgor and
necessary or appropriate under the FCC's rules and regulations for approval of
any sale or transfer of any of the capital stock or assets of the Pledgor or any
transfer of control of any FCC authorization.
