ITEM 17. UNDERTAKINGS
 
  (1) The undersigned Registrant hereby undertakes to provide to the
Underwriters at the closing specified in the Underwriting Agreement
certificates in such denominations and registered in such names as required by
the Underwriters to permit prompt delivery to each purchaser.
 
  (2) Insofar as indemnification for liabilities arising under the Securities
Act of 1933, as amended (the "Act"), may be permitted to directors, officers
or controlling persons of the Registrant pursuant to the foregoing provisions,
or otherwise, the Registrant has been advised that in the opinion of the
Securities and Exchange Commission such indemnification is against public
policy as expressed in the Act and is, therefore, unenforceable. In the event
that a claim for indemnification against such liabilities (other than the
payment by the Registrant of expenses incurred or paid by a director, officer
or controlling person of the Registrant in the successful defense of any
action, suit or proceeding) is asserted by such director, officer or
controlling person in connection with the securities being registered, the
Registrant will, unless in the opinion of its counsel the matter has been
settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Act and will be governed by the final adjudication
of such issue.
 
                                     II-2

  (3) The undersigned Registrant hereby undertakes that:
 
    (a) For purposes of determining any liability under the Act, the
  information omitted from the form of Prospectus filed as part of this
  Registration Statement in reliance upon Rule 430A and contained in a form
  of Prospectus filed by the Registrant pursuant to Rule 424(b)(1) or (4) or
  497(h) under the Act shall be deemed to be a part of this Registration
  Statement as of the time it was declared effective.
 
    (b) For the purposes of determining any liability under the Act, each
  post-effective amendment that contains a form of Prospectus shall be deemed
  to be a new Registration Statement relating to the securities offered
  therein, and the offering of such securities at that time shall be deemed
  to be the initial bona fide offering thereof.
 
  (4) The undersigned Registrant hereby undertakes:
 
    (a) To file, during any period in which offers or sales are being made, a
  post-effective amendment to this Registration Statement:
 
      (i) to include any prospectus required by Section 10(a)(3) of the
    Securities Act;
 
      (ii) to reflect in the prospectus any facts or events arising after
    the effective date of the Registration Statement (or the most recent
    post-effective amendment thereof) which, individually or in the
    aggregate, represent a fundamental change in the information set forth
    in this Registration Statement. Notwithstanding the foregoing, any
    increase or decrease in volume of securities offered (if the total
    dollar volume of securities offered would not exceed that which was
    registered) and any deviation from the low or high end of the estimated
    maximum offering range may be reflected in the form of prospectus filed
    with the Commission pursuant to Rule 424(b) if, in the aggregate, the
    changes in volume and price represent no more than a 20% change in the
    maximum aggregate offering price set forth in the "Calculation of
    Registration Fee" table in the effective registration statement;
 
      (iii) to include any material information with respect to the plan of
    distribution not previously disclosed in the Registration Statement or
    any material change to such information in the Registration Statement.
 
    (b) That, for the purpose of determining any liability under the
  Securities Act, each such post-effective amendment shall be deemed to be a
  new registration statement relating to the securities offered therein, and
  this Offering of such securities at that time shall be deemed to be the
  initial bona fide Offering thereof:
 
    (c) To remove from registration by means of a post-effective amendment
  any of the securities being registered which remain unsold at the
  termination of this Offering.

you as the underwriters (the "Underwriters"). The Firm Units consist of 809,000
Common Units to be issued and sold by the Partnership, and 23,727 Common Units
to be sold by the Selling Unitholder. The Selling Unitholder has also agreed to
grant to you an option (the "Option") to purchase up to an aggregate of 124,000

of an exchange of any standard form of written telecommunication among the
Partnership and the Underwriters and shall specify such applicable information

and after the date of the execution and delivery of the Price Determination
Agreement, this Agreement shall be deemed to incorporate, and, unless the

     The Partnership and the Selling Unitholder confirm as follows their
agreements with the Underwriters.

Section  1.  Agreement to Sell and Purchase

   (a)  On the basis of the representations, warranties and agreements of the
Partnership and the Selling Unitholder herein contained and subject to all the
terms and conditions of this Agreement, (i) the Partnership agrees to issue and
sell to each Underwriter, (ii) the Selling Unitholder agrees to sell to each
Underwriter and (iii) each Underwriter, severally and not jointly, agrees to
purchase from the Partnership and the Selling Unitholder, at the purchase price
per Firm Unit to be agreed upon by the Underwriters and the Partnership in
accordance with Section 1(c) or 1(d) hereof and set forth in the Price
Determination Agreement, the number of Firm Units (subject to such adjustments
to eliminate fractional units as the Underwriters may determine) which bears the
same proportion to the total number of Firm Units to be sold by the Partnership
and the Selling Unitholder as the number of Firm Units set forth opposite the
name of such Underwriter in Schedule 1 bears to the total number of Firm Units,
plus such additional number of Firm Units which such Underwriter may become
obligated to purchase pursuant to Section 8 hereof.  Schedule 1 may be attached
to the Price Determination Agreement.

          (b) Subject to all the terms and conditions of this Agreement, the
Selling Unitholder grants the Option to the Underwriters to purchase, severally
and not jointly, up to 124,000 Option Units from the Selling Unitholder at the
same price per Option Unit as the Underwriters shall pay for each of the Firm
Units.  The Option may be exercised only to cover over-allotments in the sale of
the Firm Units by the Underwriters and may be exercised in whole or in part at
any time (but not more than once) on or before the 30th day after the date of
this Agreement (or, if the Selling Unitholder has elected to rely on Rule 430A,
on or before the 30th day after the date of the Price Determination Agreement),
upon written or telegraphic notice (the "Option Units Notice") by the
Underwriters to the Selling Unitholder no later than 12:00 noon, New York City
time, at least two and no more than five business days before the date specified
for closing in the Option Units Notice (the "Option Closing Date") setting forth
the aggregate number of Option Units to be purchased and the time and date for
such purchase.  On the Option Closing Date, the Selling Unitholder will sell to
the Underwriters the number of Option Units set forth in the Option Units
Notice, and each Underwriter will purchase such percentage of the Option Units
as is equal to the percentage of Firm Units that such Underwriter is purchasing
as adjusted by the Underwriters in such manner as they deem advisable to avoid
fractional units.

          (c) The initial public offering price per Firm Unit and the purchase
price per Firm Unit to be paid by the Underwriters shall be agreed upon and set
forth in the Price Determination Agreement, if the Partnership has elected to
rely on Rule 430A.  In the event such price has not been agreed upon and the
Price Determination Agreement has not been executed by the close of business on
the fourteenth business day following the date on which the Registration
Statement (as hereinafter defined) becomes effective, this Agreement shall
terminate forthwith, without liability of any party to any other party except
that Section 6 shall remain in effect.

                                      -2-

          (d) If the Partnership has elected not to rely on Rule 430A, the
initial public offering price per Firm Unit and the purchase price per Firm Unit
to be paid by the Underwriters shall be agreed upon and set forth in the Price
Determination Agreement, which shall be dated the date hereof, and an amendment
to the Registration Statement containing such per unit price information shall
be filed before the Registration Statement becomes effective.

Section  2.  Delivery and Payment

   Delivery of the Firm Units shall be made to the Underwriters for their

defined). Such payment shall be made at 10:00 a.m., New York City time, on the

offering of the Units to the public is made by the Underwriters or at such time
on such other date, not later than ten business days after such date, as may be

     Certificates evidencing the Units shall be in definitive form and shall be
registered in such names and in such denominations as the Underwriters shall
request at least two business days prior to the Closing Date or the Option
Closing Date, as the case may be, by written notice to (i) the Partnership and
the Selling Unitholder, in the case of the Closing Date, and (ii) to the Selling
Unitholder, in the case of the Option Closing Date.  For the purpose of
expediting the checking and packaging of certificates for the Units, the

Selling Unitholder agrees to make such certificates to be sold by the Selling
Unitholder available for inspection at least 24 hours prior to the Closing Date,

Underwriters shall be borne by the Partnership.  The Partnership will pay and
save each Underwriter and any subsequent holder of the Units harmless from any
and all liabilities with respect to or resulting from any failure or delay in
paying Federal and state stamp and other transfer taxes, if any, which may be
payable or determined to be payable in connection with the original issuance or
sale to such Underwriter of the Firm Units and Option Units.

Section  3.  Representations and Warranties

   The Partnership represents, warrants and covenants to each Underwriter that:

          (a) A registration statement (Registration No. 333-40855) on Form S-1
relating to the Units, including a preliminary prospectus and such amendments to
such registration statement as may have been required to the date of this
Agreement, has been prepared by the Partnership under the provisions of the
Securities Act of 1933, as amended (the "Act"), and the rules and regulations
(collectively referred to as the "Rules and Regulations") of the Securities and

Commission.  The term "preliminary prospectus" as used herein means a
preliminary prospectus as contemplated by Rule 430 or Rule 430A ("Rule 430A") of
the Rules and Regulations included at any time as part of the registration
statement.  Copies of such registration statement and amendments and of each
related preliminary prospectus have been delivered to the Underwriters.  The
term "Registration Statement" means the registration statement as amended at the
time it becomes or became effective (the "Effective Date"), including financial
statements and all exhibits and any information deemed to be included by Rule
430A or Rule 434 of the Rules and Regulations.  If the Partnership files a
registration statement to register a portion of the Units and relies on Rule
462(b) of the Rules and Regulations for such registration statement to become
effective upon filing with the Commission (the "Rule 462 Registration
Statement"), then any reference to the "Registration Statement" shall be deemed
to include the Rule 462 Registration Statement, as amended from time to time.
The term "Prospectus" means the prospectus as first filed with the Commission
pursuant to Rule 424(b) of the Rules and Regulations or, if no such filing is
required, the form of final prospectus included in the Registration Statement at
the Effective Date.

          (b) On the Effective Date, the date the Prospectus is first filed with

any post-effective amendment to the Registration Statement becomes effective or
any amendment or supplement to the Prospectus is filed with the Commission, the
Registration Statement and the Prospectus (as amended or as supplemented if the
Partnership shall have filed with the Commission any amendment or supplement
thereto), including the financial statements included in the Prospectus, did or
will comply with all applicable provisions of the Act and the Rules and
Regulations and will contain all statements required to be stated therein in
accordance with the Act and the Rules and Regulations.  On the Effective Date
and when any post-effective amendment to the Registration Statement becomes
effective, no part of the Registration Statement or any such amendment did or
will contain any untrue statement of a material fact or omit to state a material
fact required to be stated therein or necessary in order to make the statements
therein not misleading.  At the Effective Date, the date the Prospectus or any
amendment or supplement to the Prospectus is filed with the Commission and at
the Closing Date and, if later, the Option Closing Date, the Prospectus did not

material fact necessary to make the statements therein, in the light of the
circumstances under which they were made, not misleading.  The foregoing
representations and warranties in this Section 3(b) do not apply to any
statements or

with a 1% general partner interest in the Partnership; such general partner
interest is duly authorized by the Agreement of Limited Partnership of the
Partnership (the "Partnership Agreement") among the General Partner and limited
partners of the Partnership, and was validly issued to the General Partner; and
the General Partner owns such general partner interest free and clear of all
liens, encumbrances, security interests, equities, charges or claims (except for

not, individually or in the aggregate, material) other than those created by or
arising under the Delaware Act, the Bank Credit Facilities or the First Mortgage
Note Agreement.

          (j) All of the issued and outstanding capital stock of the General
Partner has been duly authorized and was validly issued, and is fully paid and

Partner free and clear of all liens, encumbrances, security interests, equities,

          (k) The outstanding Common Units have been, and the Units to be issued
and sold by the Partnership upon such issuance will be, duly authorized, validly
issued, fully paid and nonassessable and will not be subject to any preemptive
or similar right.  The description of the Common Units in the Registration

accurate in all respects.  Except as set forth in the Prospectus, the
Partnership does not have outstanding, and at the Closing Date will not have

the consolidated results of operations and cash flows of the Partnership for the
respective periods covered thereby, all in conformity with generally accepted

all material respects the information shown therein, (ii) have been prepared in
accordance with the Commission's rules and guidelines with respect to pro forma
financial statements and (iii) have been properly computed on the bases
described therein.  The assumptions used in the preparation of the pro forma

referred to therein.  No other financial statements or schedules of the

Date, except as set forth in or contemplated by the Registration Statement and
the Prospectus, (i) there has not been and will not have been any change in the

business prospects, condition (financial or otherwise) or results of operations
of any of the Star Entities, arising for any reason whatsoever, (ii) none of the
Star Entities has incurred nor will it incur any material liabilities or

Entities or Petro or any of their respective directors or officers in their
capacity as such, before or by any Federal or state court, commission,
regulatory body, administrative agency or other governmental body, domestic or
foreign, wherein an unfavorable ruling, decision or finding might materially and

is bound or affected.  To the best knowledge of the Partnership and each of its
Subsidiaries, no other party under any contract or other agreement to which it

taking by the Partnership of any action contemplated hereby, except such as have
been obtained under the Act or the Rules and Regulations and such as may be
required under state securities or Blue Sky laws or the by-laws and rules of the
National Association of Securities Dealers, Inc. (the "NASD") in connection with
the purchase and distribution by the Underwriters of the Units.

          (s) The Partnership has full power and authority to enter into this

the Partnership. The performance of this Agreement and the consummation of the
transactions contemplated hereby and the application of the net proceeds from
the offering and sale of the Units in the manner set forth in the Prospectus
under "Use of Proceeds" will not result in the creation or imposition of any
lien, charge or encumbrance upon any of the assets of the Partnership or any of
its Subsidiaries pursuant to the terms or provisions of, or result in a breach
or violation of any of the terms or provisions of, or constitute a default
under, or give any other party a right to terminate any of its obligations
under, or result in the acceleration of any obligation under, the Partnership
Agreement of the Partnership or certificate of incorporation or by-laws, as the
case may be, of any of its Subsidiaries, any contract or other agreement to
which the Partnership or any of its Subsidiaries is a party or by which the
Partnership or any of its Subsidiaries or any of its properties is bound or
affected, or violate or conflict with any judgment, ruling, decree, order,
statute, rule or regulation of any court or other governmental agency or body
applicable to the business or properties of the Partnership or any of its
Subsidiaries.

properties and assets described in the Prospectus as owned by it, free and clear
of all liens, charges, encumbrances or restrictions, except such as are

                                      -9-
<PAGE>
 
leases for the properties described in the Prospectus as leased by it, with such
exceptions as are not material and do not materially interfere with the use made
and proposed to be made of such properties by the Partnership and such
Subsidiaries.

          (v) There is no document or contract of a character required to be

other unpatented and/or unpatentable proprietary or confidential information,
systems or procedures), trademarks, services marks and trade names
(collectively, "patent and proprietary rights") presently employed by them or
which are necessary in connection with the conduct of the business now operated
by them as set forth in the Registration Statement and the Prospectus and,
except as set forth on Schedule 2 hereto, neither the Partnership nor any of its
Subsidiaries has received any written notice or otherwise has actual knowledge
of any infringement of or conflict with asserted rights of others or any other
claims with respect to any 

                                      -10-
<PAGE>
 
patent or proprietary rights, or of any basis for rendering any patent and
proprietary rights invalid or inadequate to protect the interest of the
Partnership or any of its Subsidiaries.

          (bb) Neither the Partnership nor any of its Subsidiaries nor, to the
Partnership's knowledge, any employee or agent of the Partnership or any
Subsidiary has made any payment of funds of the Partnership or any Subsidiary or
received or retained any funds in violation of any law, rule or regulation or of
a character required to be disclosed in the Prospectus.

          (cc) The Partnership has complied, and until the completion of the
distribution of the Units will comply, with all of the provisions of (including,
without limitation, filing all forms required by) Section 517.075 of the Florida
Securities and Investor Protection Act and Regulation 3E-900.001 issued
thereunder with respect to the offering and sale of the Units.

          (dd) The Star Entities (i) are in compliance with any and all
applicable foreign, federal, state and local laws and regulations relating to
the protection of human health and safety, the environment or imposing liability
or standards of conduct concerning any Hazardous Material (as hereinafter
defined) ("Environmental Laws"), (ii) have received all permits, licenses or
other approvals required of them under applicable Environmental Laws to conduct
their respective businesses and (iii) are in compliance with all terms and
conditions of any such permit, license or approval, except where such
noncompliance with Environmental Laws, failure to receive required permits,
licenses or other approvals or failure to comply with the terms and conditions
of such permits, licenses or approvals would not, individually or in the
aggregate result in a material adverse effect on the condition (financial or
otherwise) or on the earnings, business, properties, business prospects or
operations of the Partnership and its Subsidiaries, taken as a whole. The term
"Hazardous Material" means (A) any "hazardous substance" as defined by the
Comprehensive Environmental Response, Compensation and Liability Act of 1980, as
amended, (B) any "hazardous waste" as defined by the Resource Conservation and
Recovery Act, as amended, (C) any petroleum or petroleum product, (D) any
polychlorinated biphenyl and (E) any pollutant or contaminant or hazardous,
dangerous, or toxic chemical, material, waste or substance regulated under or
within the meaning of any other Environmental Law.

          (ee) Each of the Star Entities maintains insurance with respect to its
properties and business of the types and in amounts generally deemed adequate
for its business and consistent with insurance coverage maintained by similar
companies and businesses, all of which insurance is in full force and effect.

          (ff) Each of the Star Entities and Petro has filed all material
federal, state and foreign income and franchise tax returns and has paid all
taxes shown as due thereon, other than taxes which are being contested in good
faith and for which adequate reserves have been established in accordance with
GAAP; and none of the Star Entities nor Petro has knowledge of any tax
deficiency which has been or might be asserted or threatened against any such
entity.  There are no tax returns of any Star Entity or of Petro that are
currently being audited by state, local or federal taxing authorities or
agencies (and with respect to which any such entity has received notice), where

                                      -11-
<PAGE>

 
the findings of such audit, if adversely determined, would result in a material
adverse effect on the condition (financial or otherwise) or on the earnings,
business, properties, business prospects or operations of the Partnership and
its Subsidiaries, taken as a whole.

          (gg) With respect to each employee benefit plan, program and
arrangement (including, without limitation, any "employee benefit plan" as
defined in Section 3(3) of the Employee Retirement Income Security Act of 1974,
as amended ("ERISA")) maintained or contributed to by any Star Entity, or with
respect to which any Star Entity could incur any liability under ERISA
(collectively, the "Benefit Plans"), no event has occurred and, to the best
knowledge of any of the Star Entities, there exists no condition or set of
circumstances, in connection with which any such entity could be subject to any
liability under the terms of such Benefit Plan, applicable law (including,
without limitation, ERISA and the Internal Revenue Code of 1986, as amended) or
any applicable agreement that could materially adversely affect the business,
properties, business prospects, condition (financial or otherwise) or results of
operations of the Star Entities, taken as a whole.

     The Selling Unitholder warrants and represents to each Underwriter that:

encumbrances and claims whatsoever, and (ii) full legal right and power, and all
authorizations and approvals required by law, to sell, transfer and deliver such
Units to the Underwriters hereunder and to make the representations, warranties
and agreements made by the Selling Unitholder herein.  Upon the delivery of and
payment for such Units hereunder, the Selling Unitholder will deliver good and

sold by the Selling Unitholder to the Underwriters hereunder will have been
fully paid or provided for by the Selling Unitholder and all laws imposing such
taxes will have been fully complied with.

          (D) The performance of this Agreement and the consummation of the
transactions contemplated hereby will not result in the creation or imposition
of any lien, charge or encumbrance upon any of the assets of the Selling
Unitholder pursuant to the terms or provisions of, or result in a breach or
violation of any of the terms or provisions of, or constitute a default under,
or result in the acceleration of any obligation under, the organizational
documents of the Selling Unitholder, or, 


                                      -12-
<PAGE>

any contract or other agreement to which the Selling Unitholder is a party or by
which the Selling Unitholder or any of its property is bound or affected, or

          (E) No consent, approval, authorization or order of, or any filing or
declaration with, any court or governmental agency or body is required for the
consummation by the Selling Unitholder of the transactions on its part
contemplated herein except such as have been obtained under the Act or the Rules
and Regulations and such as may be required under state securities or Blue Sky
laws or the by-laws and rules of the NASD in connection with the purchase and
distribution by the Underwriters of the Units to be sold by the Selling
Unitholder.

          (F) All information with respect to the Selling Unitholder contained
in the Registration Statement and the Prospectus (as amended or supplemented, if
the Partnership shall have filed with the Commission any amendment or supplement
thereto) complied and will comply with all applicable provisions of the Act and
the Rules and Regulations, contains and will contain all statements required to
be stated therein in accordance with the Act and the Rules and Regulations, and
does not and will not contain an untrue statement of a material fact or omit to
state a material fact required to be stated therein or necessary in order to
make the statements therein not misleading.

          (G) To the best knowledge of the Selling Unitholder, the
representations and warranties of the Partnership contained in this Section 3
are true and correct.

          (H) Neither the Selling Unitholder nor any of its directors, officers
or controlling persons has taken, directly or indirectly, any action intended,
or which might reasonably be expected, to cause or result in, under the Act or

the Units.

          (I) The Selling Unitholder has been duly organized and is validly
existing in good standing as a corporation under the laws of the State of
Delaware.  The Selling Unitholder has all necessary corporate power and
authority to own or lease its properties and conduct its business and to act as
general partner of the Partnership and the Operating Partnership, in each case
in all material respects as described in the Registration Statement, and the
Selling Unitholder is duly qualified or registered as a foreign corporation for
the transaction of business and is in good standing under the laws of each
jurisdiction in which the character of the business conducted by it or the
location of the properties owned or leased by it make such qualification or
registration necessary (except where the failure to so qualify or register would
not have a material adverse effect on the condition (financial or other),
results of operations or business of the Selling Unitholder, or to subject the
Selling Unitholder, the Partnership or the limited partners of the Partnership
to any material liability or disability).

          (J) The Units to be sold by the Selling Unitholder pursuant to this
Agreement have been duly authorized and are validly issued, fully paid and non-
assessable.

Section  4.  Agreements of the Partnership

   The Partnership agrees with the Underwriters as follows:

          (a) The Partnership will not, either prior to the Effective Date or
thereafter during such period as the Prospectus is required by law to be
delivered in connection with sales of the Units by an Underwriter or dealer,
file any amendment or supplement to the Registration Statement or the
Prospectus, unless a copy thereof shall first have been submitted to the
Underwriters within a reasonable period of time prior to the filing thereof and
the Underwriters shall not have objected thereto in good faith.

          (b) The Partnership will use its best efforts to cause the
Registration Statement to become effective, and will notify the Underwriters
promptly, and will confirm such advice in writing, (1) when the Registration
Statement has become effective and when any post-effective amendment thereto
becomes effective, (2) of any request by the Commission for amendments or
supplements to the Registration Statement or the Prospectus or for additional
information, (3) of the issuance by the Commission of any stop order suspending
the effectiveness of the Registration Statement or the initiation of any
proceedings for that purpose or the threat thereof, (4) of the happening of any
event during the period mentioned in the second sentence of Section 4(e) that in
the judgment of the Partnership makes any statement made in the Registration
Statement or the Prospectus untrue or that requires the making of any changes in
the Registration Statement or the Prospectus in order to make the statements
therein, in light of the circumstances in which they are made, not misleading
and (5) of receipt by the Partnership or any representative or attorney of the
Partnership of any other communication from the Commission relating to the
Partnership, the Registration Statement, any preliminary prospectus or the
Prospectus.  If at any time the Commission shall issue any order suspending the
effectiveness of the Registration Statement, the Partnership will make every
reasonable effort to obtain the withdrawal of such order at the earliest
possible moment.  The Partnership will use its best efforts to comply with the
provisions of and make all requisite filings with the Commission pursuant to
Rule 430A and to notify the Underwriters promptly of all such filings.

          (c) The Partnership will furnish to the Underwriters, without charge,
two signed copies of the Registration Statement and of any post-effective
amendment thereto, including financial statements and schedules, and all
exhibits thereto.

          (d) The Partnership will comply with all the provisions of any
undertakings contained in the Registration Statement.

          (e) On the Effective Date, and thereafter from time to time, the
Partnership will deliver to each of the Underwriters, without charge, as many
copies of the Prospectus or any amendment or supplement thereto as the
Underwriters may reasonably request.  The Partnership consents to the use of the
Prospectus or any amendment or supplement thereto by the Underwriters and by all
dealers to whom the Units may be sold, both in connection with the offering or
sale of the 

                                      -14-
<PAGE>
 
Units and for any period of time thereafter during which the Prospectus is
required by law to be delivered in connection therewith. If during such period
of time any event shall occur which in the judgment of the Partnership or
counsel to the Underwriters should be set forth in the Prospectus in order to
make any statement therein, in the light of the circumstances under which it was
made, not misleading, or if it is necessary to supplement or amend the
Prospectus to comply with law, the Partnership will forthwith prepare and duly
file with the Commission an appropriate supplement or amendment thereto, and
will deliver to each of the Underwriters, without charge, such number of copies
thereof as the Underwriters may reasonably request.

          (f) Prior to any public offering of the Units by the Underwriters, the
Partnership will cooperate with the Underwriters and counsel to the Underwriters
in connection with the registration or qualification of the Units for offer and
sale under the securities or Blue Sky laws of such jurisdictions as the
Underwriters may request; provided, that in no event shall the Partnership be
obligated to qualify to do business in any jurisdiction where it is not now so
qualified or to take any action which would subject it to general service of
process in any jurisdiction where it is not now so subject.

          (g) During the period of five years commencing on the Effective Date,
the Partnership will furnish to the Underwriters copies of such financial
statements and other periodic and special reports as the Partnership may from
time to time distribute generally to the holders of any class of its capital
units, and will furnish to the Underwriters copies of each annual or other
report it shall be required to file with the Commission.

          (h) The Partnership will make generally available to holders of its
securities as soon as may be practicable but in no event later than the last day
of the fifteenth full calendar month following the calendar quarter in which the
Effective Date falls, an earnings statement (which need not be audited but shall
be in reasonable detail) for a period of 12 months ended commencing after the
Effective Date, and satisfying the provisions of Section 11(a) of the Act
(including Rule 158 of the Rules and Regulations).

          (i) Whether or not the transactions contemplated by this Agreement are
consummated or this Agreement is terminated, the Partnership will pay, or
reimburse if paid by the Underwriters, all costs and expenses incident to the
performance of the obligations of the Partnership and Selling Unitholder under
this Agreement, including but not limited to costs and expenses of or relating
to (1) the preparation, printing and filing of the Registration Statement and
exhibits to it, each preliminary prospectus, the Prospectus and any amendment or
supplement to the Registration Statement or the Prospectus, (2) the preparation
and delivery of certificates representing the Units, (3) the word processing,
printing and reproduction of this Agreement, the Agreement Among Underwriters,
any Dealer Agreements and any Underwriters' Questionnaire, (4) furnishing

Registration Statement, the Prospectus and any preliminary prospectus, and all
amendments and supplements thereto, as may be requested for use in connection
with the offering and sale of the Units by the Underwriters or by dealers to
whom Units may be sold, (5) the listing of the Units on Nasdaq, (6) any filings
required 

                                      -15-
<PAGE>
 
to be made by the Underwriters with the NASD, and the fees, disbursements and
other charges of counsel for the Underwriters in connection therewith, (7) the
registration or qualification of the Units for offer and sale under the
securities or Blue Sky laws of such jurisdictions designated pursuant to Section
4(f), including the fees, disbursements and other charges of counsel to the
Underwriters in connection therewith, and the preparation and printing of
preliminary, supplemental and final Blue Sky memoranda, (8) counsel to the
Partnership, (9) the transfer agent for the Units and (10) the Accountants.

          (j) If this Agreement shall be terminated by the Partnership pursuant
to any of the provisions hereof (otherwise than pursuant to Section 8) or if for
any reason the Partnership or the Selling Unitholder shall be unable to perform
its obligations hereunder, the Partnership and the Selling Unitholder will
reimburse the Underwriters for all out-of-pocket expenses (including the fees,
disbursements and other charges of counsel to the Underwriters) reasonably
incurred by them in connection herewith.

          (k) The Partnership and the Selling Unitholder will not at any time,
directly or indirectly, take any action intended, or which might reasonably be
expected, to cause or result in, or which will constitute, stabilization of the
price of the units of Common Units to facilitate the sale or resale of any of
the Units.

          (l) The Partnership will apply the net proceeds from the offering and
sale of the Units to be sold by the Partnership in the manner set forth in the
Prospectus under "Use of Proceeds" and shall file such reports with the
Commission with respect to the sale of the Units and the application of the
proceeds therefrom as may be required in accordance with Rule 463 under the Act.

          (m) The Partnership and the Selling Unitholder will not, and will
cause each of its executive officers, directors and controlling persons to enter
into agreements with the Underwriters in the form set forth in Exhibit B to the
effect that they will not, for a period of 120 days after the commencement of
the public offering of the Units (the "Lock-up Period"), without the prior
written consent of PaineWebber Incorporated and Lehman Brothers Inc., sell,
contract to sell or otherwise dispose of any Common Units or rights to acquire
such units (other than (i) pursuant to employee stock option plans or in
connection with other employee incentive compensation arrangements, provided,
that the Partnership and the Selling Unitholder will not grant options to
purchase Common Units pursuant to such employee benefit plans at a price less
than the initial public offering price, or (ii) pursuant to or in connection
with an acquisition by the Partnership provided that any person receiving such
Common Units in the acquisition will also enter into an agreement with the
Underwriters in substantially the same form set forth in Exhibit B, in which
such person will agree not to sell, contract to sell or otherwise dispose of any
Common Units or rights to acquire such units for the remainder of the Lock-up
Period).

as and when incurred, to which any Underwriter, or any such person, may become
subject under the Act, the Exchange Act or other Federal or state statutory law
or regulation, at common law or otherwise, insofar as such losses, claims,
liabilities, expenses or damages arise out of or are based on (i) any untrue
statement or alleged untrue statement of a material fact contained in any
preliminary prospectus, the Registration Statement or the Prospectus or any
amendment or supplement to the Registration Statement or the Prospectus or in
any application or other document executed by or on behalf of the Partnership
and the Selling Unitholder or based on written information furnished by or on
behalf of the Partnership and the Selling Unitholder filed in any jurisdiction
in order to qualify the Units under the securities laws thereof or filed with
the Commission, (ii) the omission or alleged omission to state in such document
a material fact required to be stated in it or necessary to make the statements
in it not misleading or (iii) any act or failure to act or any alleged act or
failure to act by any Underwriter in connection with, or relating in any manner
to, the Units or the offering contemplated hereby, and which is included as part
of or referred to in any loss, claim, liability, expense or damage arising out
of or based upon matters covered by clause (i) or (ii) above (provided that the
Partnership and the Selling Unitholder shall not be liable under this clause
(iii) to the extent it is finally judicially determined by a court of competent
jurisdiction that such loss, claim, liability, expense or damage resulted
directly from any such acts or failures to act undertaken or omitted to be taken
by such underwriter through its gross negligence or willful misconduct);
provided that the Partnership and the Selling Unitholder will not be liable to
the extent that such loss, claim, liability, expense or damage arises from the
sale of the Units in the public offering to any person by an 

                                      -20-
<PAGE>
 
Underwriter and is based on an untrue statement or omission or alleged untrue
statement or omission made in reliance on and in conformity with information
relating to any Underwriter furnished in writing to the Partnership or the
Selling Unitholder by the Underwriters on behalf of any Underwriter expressly
for inclusion in the Registration Statement, any preliminary prospectus or the
Prospectus. This indemnity agreement will be in addition to any liability that
the Partnership and the Selling Unitholder might otherwise have.

          (b) Each Underwriter will indemnify and hold harmless the Partnership,
the Selling Unitholder, each person, if any, who controls the Partnership within
the meaning of Section 15 of the Act or Section 20 of the Exchange Act, each
director of the General Partner and each officer of the General Partner who
signs the Registration Statement to the same extent as the foregoing indemnity
from the Partnership and the Selling Unitholder to each Underwriter, but only
insofar as Liabilities arise out of or are based on any untrue statement or
omission or alleged untrue statement or omission made in reliance on and in
conformity with information relating to any Underwriter furnished in writing to
the Partnership or the Selling Unitholder by the Underwriters on behalf of such
Underwriter expressly for use in the Registration Statement, the Preliminary
Prospectus or the Prospectus.  This indemnity will be in addition to any
liability that each Underwriter might otherwise have; provided, however, that in
no case shall any Underwriter be liable or responsible for any amount in excess
of the underwriting discounts and commissions received by such Underwriter.

          (c) Any party that proposes to assert the right to be indemnified
under this Section 6 will, promptly after receipt of notice of commencement of
any action against such party in respect of which a claim is to be made against
an indemnifying party or parties under this Section 6, notify each such
indemnifying party of the commencement of such action, enclosing a copy of all
papers served, but the omission so to notify such indemnifying party will not
relieve it from any liability that it may have to any indemnified party under
the foregoing provisions of this Section 6 unless, and only to the extent that,
such omission results in the forfeiture of substantive rights or defenses by the
indemnifying party.  If any such action is brought against any indemnified party
and it notifies the indemnifying party of its commencement, the indemnifying
party will be entitled to participate in and, to the extent that it elects by
delivering written notice to the indemnified party promptly after receiving
notice of the commencement of the action from the indemnified party, jointly
with any other indemnifying party similarly notified, to assume the defense of
the action, with counsel satisfactory to the indemnified party, and after notice
from the indemnifying party to the indemnified party of its election to assume
the defense, the indemnifying party will not be liable to the indemnified party
for any legal or other expenses except as provided below and except for the
reasonable costs of investigation subsequently incurred by the indemnified party
in connection with the defense.  The indemnified party will have the right to
employ its own counsel in any such action, but the fees, expenses and other
charges of such counsel will be at the expense of such indemnified party unless
(1) the employment of counsel by the indemnified party has been authorized in
writing by the indemnifying party, (2) the indemnified party has reasonably
concluded (based on advice of counsel) that there may be legal defenses
available to it or other indemnified parties that are different from or in
addition to those available to the indemnifying party, 

                                      -21-
<PAGE>
 
(3) a conflict or potential conflict exists (based on advice of counsel to the
indemnified party) between the indemnified party and the indemnifying party (in
which case the indemnifying party will not have the right to direct the defense
of such action on behalf of the indemnified party) or (4) the indemnifying party
has not in fact employed counsel to assume the defense of such action within a
reasonable time after receiving notice of the commencement of the action, in
each of which cases the reasonable fees, disbursements and other charges of
counsel will be at the expense of the indemnifying party or parties. It is
understood that the indemnifying party or parties shall not, in connection with
any proceeding or related proceedings in the same jurisdiction, be liable for
the reasonable fees, disbursements and other charges of more than one separate
firm admitted to practice in such jurisdiction at any one time for all such
indemnified party or parties. All such fees, disbursements and other charges
will be reimbursed by the indemnifying party promptly as they are incurred. An
indemnifying party will not be liable for any settlement of any action or claim
effected without its written consent (which consent will not be unreasonably
withheld). No indemnifying party shall, without the prior written consent of
each indemnified party, settle or compromise or consent to the entry of any
judgment in any pending or threatened claim, action or proceeding relating to
the matters contemplated by this Section 6 (whether or not any indemnified party
is a party thereto), unless such settlement, compromise or consent includes an
unconditional release of each indemnified party from all liability arising or
that may arise out of such claim, action or proceeding. Notwithstanding any
other provision of this Section 6(d), if at any time an indemnified party shall
have requested an indemnifying party to reimburse the indemnified party for fees
and expenses of counsel, such indemnifying party agrees that it shall be liable
for any settlement effected without its written consent if (i) such settlement
is entered into more than 45 days after receipt by such indemnifying party of
the aforesaid request, (ii) such indemnifying party shall have received notice
of the terms of such settlement at least 30 days prior to such settlement being
entered into and (iii) such indemnifying party shall not have reimbursed such
indemnified party in accordance with such request prior to the date of such
settlement.

          (d) In order to provide for just and equitable contribution in
circumstances in which the indemnification provided for in the foregoing
paragraphs of this Section 6 is applicable in accordance with its terms but for
any reason is held to be unavailable from the Partnership, the Selling
Unitholder or the Underwriters, the Partnership, the Selling Unitholder and the
Underwriters will contribute to the total Liabilities (including any
investigative, legal and other expenses reasonably incurred in connection with,
and any amount paid in settlement of, any action, suit or proceeding or any
claim asserted, but after deducting any contribution received by the Partnership
or the Selling Unitholder from persons other than the Underwriters, such as
persons who control the Partnership or the Selling Unitholder within the meaning
of the Act, officers of the General Partner who signed the Registration
Statement and directors of the General Partner, who also may be liable for
contribution) to which the Partnership, the Selling Unitholder and any one or
more of the Underwriters may be subject in such proportion as shall be
appropriate to reflect the relative benefits received by the Partnership and the
Selling Unitholder on the one hand and the Underwriters on the other. The
relative benefits received by the Partnership and the Selling Unitholder on the
one hand and the Underwriters on the other shall be deemed to be in the same
proportion as the total net proceeds from the offering (before deducting
expenses) received by the Partnership and the Selling


                                      -22-
<PAGE>
Unitholder bear to the total underwriting discounts and commissions received by
the Underwriters, in each case as set forth in the table on the cover page of
the Prospectus. If, but only if, the allocation provided by the foregoing
sentence is not permitted by applicable law, the allocation of contribution
shall be made in such proportion as is appropriate to reflect not only the
relative benefits referred to in the foregoing sentence but also the relative
fault of the Partnership and the Selling Unitholder, on the one hand, and the
Underwriters, on the other, with respect to the statements or omissions which
resulted in such loss, claim, liability, expense or damage, or action in respect
thereof, as well as any other relevant equitable considerations with respect to
such offering. Such relative fault shall be determined by reference to whether
the untrue or alleged untrue statement of a material fact or omission or alleged
omission to state a material fact relates to information supplied by the
Partnership, the Selling Unitholder, or the Underwriters, the intent of the
parties and their relative knowledge, access to information and opportunity to
correct or prevent such statement or omission. The Partnership, the Selling
Unitholder and the Underwriters agree that it would not be just and equitable if
contributions pursuant to this Section 6(d) were to be determined by pro rata
allocation (even if the Underwriters were treated as one entity for such
purpose) or by any other method of allocation which does not take into account
the equitable considerations referred to herein. The amount paid or payable by
an indemnified party as a result of the Liabilities, or action in respect
thereof, referred to above in this Section 6(d) shall be deemed to include, for
purpose of this Section 6(d), any legal or other expenses reasonably incurred by
such indemnified party in connection with investigating or defending any such
action or claim. Notwithstanding the provisions of this Section 6(d), no
Underwriter shall be required to contribute any amount in excess of the
underwriting discounts and commissions received by it and no person found guilty
of fraudulent misrepresentation (within the meaning of Section 11(f) of the Act)
will be entitled to contribution from any person who was not guilty of such
fraudulent misrepresentation. The Underwriters' obligations to contribute as
provided in this Section 6(d) are several in proportion to their respective
underwriting obligations and not joint. For purposes of this Section 6(d), any
person who controls a party to this Agreement within the meaning of the Act will
have the same rights to contribution as that party, and each officer of the
General Partner who signed the Registration Statement will have the same rights
to contribution as the Partnership, subject in each case to the provisions
hereof. Any party entitled to contribution, promptly after receipt of notice of
commencement of any action against such party in respect of which a claim for
contribution may be made under this Section 6(d), will notify any such party or
parties from whom contribution may be sought, but the omission so to notify will
not relieve the party or parties from whom contribution may be sought from any
other obligation it or they may have under this Section 6(d). Except for a
settlement entered into pursuant to the last sentence of Section 6(d) hereof, no
party will be liable for contribution with respect to any action or claim
settled without its written consent (which consent will not be unreasonably
withheld).

          (e) The indemnity and contribution agreements contained in this
Section 6 and the representations and warranties of the Partnership and the
Selling Unitholder contained in this Agreement shall remain operative and in
full force and effect regardless of (i) any investigation made by or on behalf
of the Underwriters, (ii) acceptance of the Units and payment therefore or (iii)
any termination of this Agreement.

                                      -23-
<PAGE>
 
          (g) The Partnership and the Selling Unitholder each hereby irrevocably
consents and agrees, for the benefit of each Underwriter and each person who
controls any Underwriter, that any action, suit or proceeding asserting a claim
for indemnification or contribution under or pursuant to this Section 6 may be
instituted by any Underwriter or any such controlling person in any state or
federal court in the Borough of Manhattan in the City of New York, and the
Partnership and the Selling Unitholder will accept the jurisdiction of such
court in such action, and waives, to the fullest extent permitted by applicable
law, any defense based upon lack of personal jurisdiction or venue.

Section  7.  Termination

   The obligations of the Underwriters under this Agreement may be terminated at
any time on or prior to the Closing Date (or, with respect to the Option Units,
on or prior to the Option Closing Date), by notice to the Partnership and the
Selling Unitholder from the Underwriters, without liability on the part of any
Underwriter to the Partnership or the Selling Unitholder, if, prior to delivery
and payment for the Units (or the Option Units, as the case may be), in the sole
judgment of the Underwriters, (i) there has been, since the respective dates as
of which information is given in the Registration Statement, any material
adverse change in the Partnership's business, properties, business prospects,
condition (financial or otherwise) or results of operations, (ii) trading in any
of the equity securities of the Partnership shall have been suspended by the
Commission, the NASD, by an exchange that lists the Units or by the Nasdaq Stock
Market, (iii) trading in securities generally on the New York Stock Exchange or
the Nasdaq Stock Market shall have been suspended or limited or minimum or
maximum prices shall have been generally established on such exchange or over
the counter market, or additional material governmental restrictions, not in
force on the date of this Agreement, shall have been imposed upon trading in
securities generally by such exchange or by order of the Commission or the NASD
or any court or other governmental authority, (iv) a general banking moratorium
shall have been declared by either Federal or New York State authorities or (v)
any material adverse change in the financial or securities markets in the United
States or in political, financial or economic conditions in the United States or
any outbreak or material escalation of hostilities or declaration by the United
States of a national emergency or war or other calamity or crisis shall have
occurred the effect of any of which is such as to make it, in the sole judgment
of the Underwriters, impracticable or inadvisable to market the Units on the
terms and in the manner contemplated by the Prospectus.

Section  8.  Substitution of Underwriters

   If any one of the Underwriters shall fail or refuse to purchase any of the
Firm Units which it agreed to purchase hereunder, and the aggregate number of
Firm Units which such defaulting Underwriter agreed but failed or refused to
purchase is not more than one-tenth of the aggregate number of Firm Units, the
other Underwriter shall be obligated to purchase the Firm Units which such
defaulting Underwriter agreed but failed or refused to purchase. If the non-
defaulting Underwriter shall fail or refuse to purchase any Firm Units and
arrangements satisfactory to the non-defaulting Underwriter or the Partnership
for the purchase of such Firm Units are not made within 48 hours after such
default, this Agreement will terminate without liability on the part of the non-


                                      -24-
<PAGE>

 
defaulting Underwriter, the Partnership or the Selling Unitholder for the
purchase or sale of any Units under this Agreement.  In any such case either the
non-defaulting Underwriter or the Partnership shall have the right to postpone
the Closing Date, but in no event for longer than seven days, in order that the
required changes, if any, in the Registration Statement and in the Prospectus or
in any other documents or arrangements may be effected.  Any action taken
pursuant to this Section 8 shall not relieve the defaulting Underwriter from
liability in respect of  any default of such Underwriter under this Agreement.

Section  9.  Miscellaneous

   Notice given pursuant to any of the provisions of this Agreement shall be in
writing and, unless otherwise specified, shall be mailed or delivered (a) if to
the Partnership, at the office of the Partnership, 2187 Atlantic Street, P.O.
Box 120011, Stamford, CT 06912-0011, Attention: [____________], or (b) if to the
Underwriters, at the offices of PaineWebber Incorporated, 1285 Avenue of the

Any such notice shall be effective only upon receipt.  Any notice under Section
7 or 8 may be made by telex or telephone, but if so made shall be subsequently
confirmed in writing.

     This Agreement has been and is made solely for the benefit of the
Underwriters, the Partnership and the Selling Unitholder and of the controlling
persons, directors and officers referred to in Section 6, and their respective
successors and assigns, and no other person shall acquire or have any right
under or by virtue of this Agreement.  The term "successors and assigns" as used
in this Agreement shall not include a purchaser, as such purchaser, of Units
from any of the Underwriters.

     All representations, warranties and agreements of the Partnership and the
Selling Unitholder contained herein or in certificates or other instruments
delivered pursuant hereto, shall remain operative and in full force and effect
regardless of any investigation made by or on behalf of any Underwriter or any
of its controlling persons and shall survive delivery of and payment for the
Units hereunder.

     THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE
LAWS OF THE STATE OF NEW YORK WITHOUT REGARD TO THE CONFLICT OF LAWS PRINCIPLES
OF SUCH STATE.

     This Agreement may be signed in two or more counterparts with the same
effect as if the signatures thereto and hereto were upon the same instrument.

     In case any provision in this Agreement shall be invalid, illegal or
unenforceable, the validity, legality and enforceability of the remaining
provisions shall not in any way be affected or impaired thereby.

                                      -25-

     The Partnership, the Selling Unitholder and the Underwriters each hereby
irrevocably waive any right they may have to a trial by jury in respect of any
claim based upon or arising out of this Agreement or the transactions
contemplated hereby.

     This Agreement may not be amended or otherwise modified or any provision
hereof waived except by an instrument in writing signed by the Underwriters, the
Partnership and the Selling Unitholder.

PAINEWEBBER INCORPORATED
LEHMAN BROTHERS INC.
c/o PaineWebber Incorporated
1285 Avenue of the Americas
New York, New York  10019

Dear Sirs:

     In consideration of the agreement of PaineWebber Incorporated and Lehman
Brothers Inc. to underwrite a proposed public offering (the "Offering") of
832,727 Common Units (the "Common Units") of Star Gas Partners, L.P., a Delaware
partnership (the "Partnership"), as contemplated by a registration statement
with respect to such units filed with the Securities and Exchange Commission on
Form S-1 (Registration No. 333-40855), the undersigned hereby agrees that the
undersigned will not, for a period of 120 days after the commencement of the
public offering of such units, without the prior written consent of PaineWebber
Incorporated and Lehman Brothers Inc., offer to sell, sell, contract to sell,
grant any option to sell, or otherwise dispose of, or require any person to file
with the Securities and Exchange Commission a registration statement under the
Securities Act of 1933 to register any units of Common Units or shares of Star
Gas Corporation, the general partner of the Partnership (the "General Partner
Shares"), or securities convertible into or exchangeable for Common Units or
General Partner Shares or warrants or other rights to acquire units of Common
Units of which the undersigned is now, or may in the future become, the
beneficial owner within the meaning of Rule 13d-3 under the Securities Exchange
Act of 1934).

                            Very truly yours,

     The Partnership and each of its Subsidiaries is a partnership duly formed
and validly existing as a limited partnership under the Delaware Revised Uniform
Limited Partnership Act, or a corporation duly organized, validly existing and
in good standing under the laws of the jurisdiction of its incorporation, and
has full power and authority to conduct all the activities conducted by it, to
own or lease all the assets owned or leased by it and to conduct its business as
described in the Registration Statement and the Prospectus.

     The General Partner has been duly organized and is validly existing in good
standing as a corporation under the laws of the State of Delaware, with all
necessary corporate power and authority to own or lease its properties and
conduct its business and to act as general partner of the Partnership and the
Operating Partnership.  All of the outstanding capital stock of the General
partner is duly authorized and validly issued and is fully paid and is
nonassessable.  To our knowledge, Petro owns all of the issued and outstanding
capital stock of the General Partner free and clear of all liens, encumbrances,
security interests, equities, charges or claims.

     Petro has been duly organized and is validly existing in good standing as a
corporation under the laws of the State of Minnesota.

duly qualified or registered as foreign limited partnerships or foreign
corporations for the transaction of business under the laws of the States of
Connecticut, Indiana, Illinois, Kentucky, Maine, Massachusetts, Michigan, New
Hampshire, New Jersey, New York, Ohio, Pennsylvania, Rhode Island and West
Virginia; and to our knowledge, such jurisdictions are the only jurisdictions in
which the character of the business conducted by the entity or the location of
the properties owned or leased by the entity make such qualification or
registration necessary (except where the failure to so qualify or register would
not have a material adverse effect on the condition (financial or other),
results of operations or business of the Star Entities, taken as a whole, or
subject the Partnership or the limited partners of the Partnership to any
material liability or disability).

       Stellar Propane Service Corp. is duly qualified or registered as a
foreign corporation for the transaction of business under the laws of the States
of Connecticut, Maine, Massachusetts, New Hampshire, New Jersey, Pennsylvania,
and Rhode Island; and to our knowledge, such jurisdictions are the only
jurisdictions in which the character of the business conducted by it or the
location of the properties owned or leased by it make such qualification or
registration necessary (except where the failure to so qualify or register would
not have a material adverse effect on the condition (financial or other),
results of operations or business of the Star Entities, taken as a whole, or
subject the Partnership or the limited partners of the Partnership to any
material liability or disability)

Entities has received any notice of proceedings relating to the revocation or

Registration Statement or any amendment thereto contained or contains any untrue
statement of a material fact or omitted or omits to state a material fact
required to be stated therein or necessary to make the statements therein not
