         (a) Units Available. Subject to adjustment as provided in Section 4(c),
the number of Units with respect to which  Awards may be granted  under the Plan
is 1,000,000.  If any Award is forfeited or otherwise  terminates or is canceled
without the  delivery  of Units,  then the Units  covered by such Award,  to the
extent of such  forfeiture,  termination or  cancellation,  shall again be Units
with respect to which Awards may be granted.
 
         (b) Sources of Units  Deliverable  Under  Awards.  Any Units  delivered
pursuant to an Award shall  consist,  in whole or in part, of Units  acquired in
the open market, from any Affiliate or other Person,  including the Partnership,

discretion.
 
         (c)  Adjustments.  In the  event  the  Committee  determines  that  any
distribution  (whether in the form of cash, Units,  other  securities,  or other
property),  recapitalization,  split,  reverse  split,  reorganization,  merger,
consolidation, split-up, spin-off, combination, repurchase, or exchange of Units
or other securities of the Partnership,  issuance of warrants or other rights to
purchase  Units  or  other  securities  of the  Partnership,  or  other  similar
transaction  or event affects the Units such that an adjustment is determined by
the Committee to be appropriate  in order to prevent  dilution or enlargement of
the benefits or potential benefits intended to be made available under the Plan,
then the Committee shall, in such manner as it may deem equitable, adjust any or
all of (i) the number and type of Units (or other  securities or property)  with
respect to which  Awards may be  granted,  (ii) the number and type of Units (or
other securities or property) subject to outstanding Awards, and (iii) the grant

         Any  Employee  and  Director  shall  be  eligible  to be  designated  a
Participant.
 
         SECTION 6.   Awards.
                      ------
 
         (a) Options.  The  Committee  shall have the authority to determine the
Employees and Directors to whom Options shall be granted, the number of Units to
be  covered  by each  Option,  whether  DERs are  granted  with  respect to such
Options,  the  exercise  price  therefor  and  the  conditions  and  limitations
applicable  to the exercise of the Option,  including  the  following  terms and
conditions and such  additional  terms and  conditions,  as the Committee  shall
determine, that are not inconsistent with the provisions or intent of the Plan.
 
                  (i) Exercise  Price.  The purchase price per Unit  purchasable
         under an Option shall be  determined  by the  Committee at the time the
         Option is  granted  and may be equal to,  greater or less than its Fair
         Market Value as of the date of grant,  as determined by the  Committee,
         in its discretion.
 
                  (ii)  Time  and  Method  of  Exercise.   The  Committee  shall
         determine  the time or times at which an  Option  may be  exercised  in
         whole or in part, and the method or methods by which any payment of the
         exercise price with respect  thereto may be made or deemed to have been
         made, which may include, without limitation,  cash, check acceptable to
         the Company, a "cashless-broker"  exercise (through procedures approved
         by the Company), other property, a note from the Participant (in a form
         and on terms acceptable to the Company, which may include such security
         arrangements  as the Company  deems  appropriate),  or any  combination
         thereof,  having a value on the  exercise  date  equal to the  relevant
         exercise price.
 
                  (iii) DERs.  To the extent  provided by the  Committee  in its
         discretion, an Option grant may include a tandem DER grant, which shall
         provide that such DERs shall be paid currently to the  Participant,  be
         credited to a Company  bookkeeping  account (with or without  interest)
         and be subject to the same  restrictions  as the tandem  Option,  or be
         subject to such other  provisions or  restrictions as determined by the
         Committee in its discretion.
 
                  (iv) Term.  Each Option  shall expire as provided in the grant
         agreement for such Option.
 
                  In the event the Committee determines, in its discretion, that
Units are not readily  available to the Company to pay a Participant on exercise
of an Option,  in lieu of delivering Units, the Committee may direct the Company
to pay the  Participant an amount in cash equal to the excess of the Fair Market
Value of a Unit and the exercise price of the Option.
<PAGE>
 
         (b)  Restricted  Units.  The  Committee  shall  have the  authority  to
determine the Employees and Directors to whom Restricted Units shall be granted,
the  number of  Restricted  Units to be granted  to each such  Participant,  the
period  during which the Award remains  subject to  forfeiture,  the  conditions
under which the Restricted Units may become vested or forfeited,  and such other
terms and  conditions as the Committee may establish with respect to such Award,
including whether DERs are granted with respect to such Restricted Units.
 
                  (i) DERs.  To the  extent  provided  by the  Committee  in its
         discretion, a grant of Restricted Units may include a tandem DER grant,
         which  shall  provide  that such DERs  shall be paid  currently  to the
         Participant,  be credited  to a Company  bookkeeping  account  (with or
         without interest) and be subject to the same restrictions as the tandem
         Award,  or be subject  to such  other  provisions  or  restrictions  as
         determined by the Committee in its discretion.
 
                 (ii) Lapse of Restrictions. Upon the vesting of each Restricted
Unit, the Participant shall be entitled to receive from the Company one Unit.
 
                  In the event the Committee determines, in its discretion, that
Units are not readily  available  to the  Company to pay such Award,  in lieu of
delivering  Units the Committee may direct the Company to pay the Participant an
amount in cash equal to the Fair Market Value of an equal number of Units.
 
         (c)      General.
                  -------
 
                  (i) Awards May Be Granted Separately or Together.  Awards may,
         in the  discretion  of the  Committee,  be granted  either  alone or in
         addition to, in tandem  with,  or in  substitution  for any other Award
         granted under the Plan or any award granted under any other plan of the
         Company or any  Affiliate.  Awards  granted in addition to or in tandem
         with other Awards or awards granted under any other plan of the Company
         or any  Affiliate  may be  granted  either  at the same time as or at a
         different time from the grant of such other Awards or awards.
 
                  (ii)     Limits on Transfer of Awards.
                           ----------------------------
 
                           (A)  Except as  provided  in (C) below,  each  Option
                  shall  be  exercisable  only  by the  Participant  during  the
                  Participant's   lifetime,   or  by  the  person  to  whom  the
                  Participant's rights shall pass by will or the laws of descent
                  and distribution.
 
                           (B) Except as provided in (C) below,  no Award and no
                  right  under  any  such  Award  may  be  assigned,  alienated,
                  pledged, attached, sold or otherwise transferred or encumbered
                  by a  Participant  otherwise  than by  will or by the  laws of
                  descent and  distribution  and any such purported  assignment,
                  alienation,  pledge, attachment, sale, transfer or encumbrance
                  shall be void and  unenforceable  against  the  Company or any
                  Affiliate.
 
<PAGE>
 
                           (C)  To  the  extent  specifically  provided  by  the
                  Committee  with respect to an Option  grant,  an Option may be
                  transferred  by a  Participant  without  consideration  to  an
                  immediate  family member of the  Participant on such terms and
                  conditions as the Committee may from time to time establish.
 
                  (iii) Unit  Certificates.  All certificates for Units or other
         securities of the Partnership  delivered under the Plan pursuant to any
         Award or the exercise  thereof  shall be subject to such stop  transfer
         orders and other restrictions as the Committee may deem advisable under
         the Plan or the rules, regulations,  and other requirements of the SEC,
         any stock  exchange upon which such Units or other  securities are then
         listed, and any applicable federal or state laws, and the Committee may
         cause a legend or  legends to be put on any such  certificates  to make
         appropriate reference to such restrictions.
 
                  (iv)  Consideration  for Grants.  Awards may be granted for no
         cash   consideration  or  for  such   consideration  as  the  Committee
         determines   including,   without   limitation,   such   minimal   cash
         consideration as may be required by applicable law.
 
                  (v)  Delivery  of Units or other  Securities  and  Payment  by
         Participant of  Consideration.  No Units or other  securities  shall be
         delivered  pursuant  to any Award  until  payment in full of any amount
         required to be paid pursuant to the Plan or the applicable  Award grant
         agreement  (including,  without  limitation,  any exercise price or tax
         withholding)  is received by the  Company.  Such payment may be made by
         such method or methods and in such form or forms as the Committee shall
         determine,  including,  without limitation, cash, withholding of Units,
         cashless broker  exercises with  simultaneous  sale, or any combination
         thereof;  provided  that  the  combined  value,  as  determined  by the
         Committee,  of all cash and cash  equivalents and the fair market value
         of any such property so tendered to the Company, as of the date of such
         tender, is at least equal to the full amount required to be paid to the
         Company pursuant to the Plan or the applicable Award agreement.
 
         SECTION 7.   Amendment and Termination.
                      -------------------------
 
         Except to the extent  prohibited by applicable law and unless otherwise
expressly provided in an Award agreement or in the Plan:
 
                  (a)  Amendments to the Plan.  Except as required by applicable
         law or the  rules of the  principal  securities  exchange  on which the
         units are traded and subject to Section  7(b)  below,  the Board or the
         Committee may amend, alter, suspend, discontinue, or terminate the Plan
         without  the  consent  of any  partner,  Participant,  other  holder or
         beneficiary of an Award, or other Person.
 
                  (b)  Amendments  to  Awards.   The  Committee  may  waive  any
         conditions  or  rights  under,  amend  any terms of, or alter any Award
 
<PAGE>
 
         theretofore granted, provided no change, other than pursuant to Section
         7(c), in any Award shall  materially  reduce the benefit to Participant
         without the consent of such Participant.
 
                  (c) Adjustment or Termination of Awards Upon the Occurrence of
         Certain Events.  The Committee is hereby authorized to make adjustments
         in the terms and  conditions of, and the criteria (if any) included in,
         Awards in  recognition  of unusual or  significant  events  (including,
         without  limitation,  the events described in Section 4(c) of the Plan)
         affecting  the   Partnership   or  the  financial   statements  of  the
         Partnership,  of changes in applicable laws, regulations, or accounting
         principles, or a change in control of the Company (as determined by its
         Board)  whenever the Committee  determines  that such  adjustments  are
         appropriate in order to prevent dilution or enlargement of the benefits
         or potential  benefits  intended to be made  available  under the Plan.
         Such  adjustments may include,  without  limitation,  accelerating  the
         exercisability  of an Award,  accelerating  the date on which the Award
         will terminate  and/or  canceling  Awards by the payment of cash and/or
         other  property  equal  to the  Option's  positive  "spread"  or,  if a
         Restricted Unit, the value of a Unit.
 
         SECTION 8.   General Provisions.
                      ------------------
 
         (a) No Rights to Awards.  No Person  shall have any claim to be granted
any  Award,   and  there  is  no  obligation  for  uniformity  of  treatment  of
Participants.  The terms  and  conditions  of  Awards  need not be the same with
respect to each recipient.
 
         (b)  Termination  of Employment.  For purposes of the Plan,  unless the
Award agreement  provides to the contrary,  a Participant shall not be deemed to
have  terminated  employment  with the Company and its  Affiliates or membership
from the  Board  until  such  date as the  Participant  is no  longer  either an
Employee or a Director,  i.e.,  a change in status from  Employee to Director or
Director to Employee shall not be a termination.
 
         (c) No  Right  to  Employment.  The  grant  of an  Award  shall  not be
construed as giving a Participant  the right to be retained in the employ of the
Company or any Affiliate or to remain on the Board, as applicable.  Further, the
Company or an Affiliate may at any time dismiss a Participant  from  employment,
free from any liability or any claim under the Plan, unless otherwise  expressly
provided in the Plan or in any Award agreement. Nothing in the Plan or any Award
agreement shall operate or be construed as constituting an employment  agreement
with any Participant and each Participant shall be an "at will" employee, unless
such Participant has entered into a separate written  employment  agreement with
the Company or an Affiliate.
 
         (d) Governing Law. The validity,  construction,  and effect of the Plan
and any  rules and  regulations  relating  to the Plan  shall be  determined  in
accordance  with the laws of the State of Delaware and  applicable  federal law,
without giving effect to principles of conflicts of law.
 
         (e)  Severability.  If any  provision  of the  Plan or any  Award is or
becomes  or  is  deemed  to  be  invalid,   illegal,  or  unenforceable  in  any
jurisdiction or as to any Person or Award,  or would  disqualify the Plan or any
 
<PAGE>
 
Award under any law deemed applicable by the Committee,  such provision shall be
construed or deemed amended to conform to the  applicable  laws, or if it cannot
be construed or deemed amended without,  in the  determination of the Committee,
materially altering the intent of the Plan or the Award, such provision shall be
stricken as to such jurisdiction,  Person or Award and the remainder of the Plan
and any such Award shall remain in full force and effect.
 
         (f) Other Laws. The Committee may refuse to issue or transfer any Units
or other consideration under an Award if, in its sole discretion,  it determines
that the  issuance or transfer or such Units or such other  consideration  might
violate any applicable law or regulation,  the rules of any securities exchange,
or entitle the  Partnership  or an Affiliate  to recover the same under  Section
16(b)  of the  Exchange  Act,  and any  payment  tendered  to the  Company  by a
Participant, other holder or beneficiary in connection with the exercise of such
Award  shall  be  promptly  refunded  to the  relevant  Participant,  holder  or
beneficiary.
 
         (g) Unsecured Creditors. Neither the Plan nor any Award shall create or
be  construed  to create a  fiduciary  relationship  between  the Company or any
Affiliate and a Participant  or any other Person.  To the extent that any Person
acquires a right to receive payments from the Company or any Affiliate  pursuant
to an Award,  such  right  shall be no  greater  than the  right of any  general
unsecured creditor of the Company or the Affiliate.
 
         (h) No  Fractional  Units.  No  fractional  Units  shall be  issued  or
delivered  pursuant to the Plan or any Award,  and the Committee shall determine
whether cash, other  securities,  or other property shall be paid or transferred
in lieu of any fractional  Units or whether such fractional  Units or any rights
thereto shall be canceled, terminated, or otherwise eliminated.
 
         (i) Headings. Headings are given to the Sections and subsections of the
Plan solely as a convenience to facilitate reference. Such headings shall not be
deemed in any way material or relevant to the construction or  interpretation of
the Plan or any provision thereof.
 
         SECTION 9.   Term of the Plan.
                      ----------------
 
         The Plan shall be  effective  on the date of its  approval by the Board
and shall  continue  until all available  Units under the Plan have been paid to
Participants or the earlier termination of the Plan by action of the Board.
