Ladies and Gentlemen:

Introductory.  Rentech, Inc., a Colorado corporation (the “Company”),
proposes, pursuant to the terms of this Placement Agent Agreement (this “Agreement”)
and the Subscription Agreements in the form of Exhibit A attached hereto
(the “Subscription Agreements”) entered into with the purchasers
identified therein (each a “Purchaser” and collectively, the “Purchasers”),
to sell to the Purchasers an aggregate of 20,092,160 units (the “Units”),
each comprised of one share (the “Shares”) of common stock, par value
$0.01 per share (the “Common Stock”) of the Company (including any associated right to purchase shares of
Series 1998-C Participating Cumulative Preference Stock, $10 par value , under
the Shareholder Rights Plan, dated as of January 18, 2005, as amended (each a “Right”
and collectively, the “Rights”), if any, and warrants (the “Warrants”),
initially to purchase 0.20 additional shares, subject to adjustment (the “Warrant
Shares,” and together with the Shares, the “Total Shares”), of
Common Stock of the Company.  The Shares
and Warrants are referred to collectively as the “Securities.”  The Company hereby confirms its agreement
with Credit Suisse Securities (USA) LLC (“Credit Suisse” or the “Placement
Agent”), as set forth below.

Section
1.  Agreement to Act as Placement Agent; Placement of Shares.  On the basis of the representations,
warranties and agreements of the Company herein contained, and subject to all
the terms and conditions of this Agreement:

(a)  The Company hereby authorizes the Placement
Agent to act as its exclusive agent to solicit offers for the purchase of all
or part of the Securities from the Company in connection with the proposed
offering of the Securities (the “Offering”).  Until the earlier of the Closing Date (as
defined below) and the termination of this Agreement, the Company shall not,
without the prior consent of the Placement Agent, solicit or accept offers to
purchase Securities otherwise than through the Placement Agent.

(b)  The Placement Agent agrees, as agent of the
Company, to use its best efforts to solicit offers to purchase the Securities
from the Company on the terms and subject to the conditions set forth in the
Prospectus (as defined below).  The
Placement Agent has no authority to bind the Company with respect to any
prospective offer to purchase Securities. 
The Placement Agent shall not have any liability to the Company in the
event any such purchase is not consummated for any reason.  Under no circumstances will the Placement
Agent be obligated to purchase any Securities for its own accounts and, in
soliciting purchases of Securities, the Placement Agent shall act solely as the
Company’s 

 1
 

agent and not as principal.  Notwithstanding the foregoing, the Placement
Agent (or its affiliates) may, solely at its discretion and without any
obligation to do so, purchase Securities as principal.

(c)  Offers for the purchase of Securities may be
solicited by the Placement Agent as agent for the Company at such times and in
such amounts as the Placement Agent deems advisable.  The Placement Agent shall communicate to the
Company, orally or in writing, each offer to purchase Securities received by it
as Placement Agent of the Company.  The
Company shall have the sole right to accept offers to purchase the Securities
and may reject any such offer, in whole or in part.  The Placement Agent shall have the right, in
its reasonable discretion, without notice to the Company, to reject any offer
to purchase Securities received by it, in whole or in part, and any such
rejection shall not be deemed a breach of its agreement contained herein.

(d)  The purchases of the Securities by the
Purchasers shall be evidenced by the execution of a Subscription Agreement by
each of the parties thereto.

(e)  As compensation for services rendered, on the
Closing Date, the Company shall pay or cause to be paid to the Placement Agent
by wire transfer of immediately available funds to an account or accounts
designated by the Placement Agent, an aggregate amount equal to five percent
(5%) of the gross proceeds received by the Company from the sale of the
Securities on such Closing Date.

(f)  No Securities which the Company has agreed to
sell pursuant to this Agreement shall be deemed to have been purchased and paid
for, or sold by the Company, until such Securities shall have been delivered to
the Purchaser thereof against payment by such Purchaser.  If the Company shall default in its
obligations to deliver Securities to a Purchaser whose offer it has accepted,
the Company shall indemnify and hold the Indemnified Parties (as defined below)
harmless against any loss, claim, damage or liability directly or indirectly arising
from or as a result of such default by the Company.

Agreement, such Registration Statement and the Prospectus will conform in all
material respects to the requirements of the Securities Act and the Rules and
Regulations, and neither of such documents will include any untrue statement of

individually or in the aggregate reasonably be expected to have a Material
Adverse Effect.

(u)  Except as

Statutory Prospectus (including the Prospectus) pursuant to and in accordance
with Rule 424(b)(2) (or, if applicable and consented to by the Placement Agent,
subparagraph (5)) not later than the second business day following the earlier
of the date it is first used or the date of the Subscription Agreements.  The Company has complied and will comply with
Rule 433.

(b)  The Company will advise the Placement Agent
promptly of any proposal to amend or supplement either Registration Statement
or any Statutory Prospectus prior to the Closing Date (including by incorporation
by reference of any report filed under the Exchange Act) and will afford the
Placement Agent a reasonable opportunity to comment on any such proposed
amendment or supplement; and the Company will also advise the Placement Agent
promptly of the filing of any such amendment or supplement and of the
institution by the Commission of any stop order proceedings in respect of
either Registration Statement or of any part thereof and will use its best
efforts to prevent the issuance of any such stop order and to obtain as soon as
possible its lifting, if issued.

 10
 

(c)  If, at any time when a prospectus relating to
the Securities is required to be delivered by the Placement Agent or dealer in
connection with the Offering, any event occurs as a result of which the
Prospectus as then amended or supplemented would include an untrue statement of
a material fact or omit to state any material fact necessary to make the
statements therein, in the light of the circumstances under which they were
made, not misleading, or if it is necessary at any time to amend the Prospectus
to comply with the Securities Act, the Company promptly will notify the
Placement Agent of such event and will promptly prepare and file with the
Commission, at its own expense, an amendment or supplement which will correct
such statement or omission or an amendment which will effect such
compliance.  Neither the Placement Agent’s
consent to, nor the Placement Agent’s delivery of, any such amendment or
supplement shall constitute a waiver of any of the conditions set forth in
Section 5 hereof.

(d)   As soon as practicable, but not later
than 16 months, after the date of each Subscription Agreement, the Company will
make generally available to its securityholders an earning statement covering a
period of at least 12 months beginning after the date of such Subscription
Agreement and satisfying the provisions of Section 11(a) of the Securities Act.

(e)   The Company will furnish to the
Placement Agent copies of each Registration Statement, including all exhibits,
any related preliminary prospectus, any related preliminary prospectus
supplement, the Prospectus and all amendments and supplements to such
documents, in each case as soon as available and in such quantities as the
Placement Agent reasonably requests.  The
Company will pay the expenses of printing and distributing to the Placement
Agent and Purchasers all such documents.

(f)            The Company shall cooperate with the Placement
Agent and counsel for the Placement Agent to qualify or register the Securities
for sale under (or obtain exemptions from the application of) the state
securities or blue sky laws of those jurisdictions within the United States
designated by the Placement Agent, shall comply with such laws and shall
continue such qualifications, registrations and exemptions in effect so long as
required for the distribution of the Securities.  The Company shall not be required to qualify
as a foreign corporation or to take any action that would subject it to general
service of process in any such jurisdiction where it is not presently qualified
or where it would be subject to taxation as a foreign corporation where it is
not now so subject.  The Company will
advise the Placement Agent promptly of the suspension of the qualification or
registration of (or any such exemption relating to) the Securities for
offering, sale or trading in any jurisdiction or any initiation or threat of
any proceeding for any such purpose, and in the event of the issuance of any
order suspending such qualification, registration or exemption, the Company
shall use its commercially reasonable efforts to obtain the withdrawal thereof
as promptly as reasonably practicable.

(g)  The Company
will not take, directly or indirectly, any action designed to cause or result
in, or that has constituted or might reasonably be expected to constitute,
under the Exchange Act or otherwise, the stabilization or manipulation of the
price of any securities of the Company to facilitate the sale or resale of the
Securities.

The Placement Agent may, in its sole
discretion, waive in writing the performance by the Company of any one or more
of the foregoing covenants or extend the time for their performance.

Section
4.  Free Writing Prospectuses.

(a)  The Company represents and agrees that,
unless it obtains the prior consent of the Placement Agent, and the Placement
Agent represents and agrees that, unless it obtains the prior consent of the
Company, it has not made and will not make any offer relating to the Securities
that would constitute an Issuer Free Writing Prospectus, or that would
otherwise constitute a “free writing prospectus,” as defined in Rule 405,
required to be filed with the Commission. 
Any such free writing prospectus consented to by the Company and the
Placement Agent is hereinafter referred to as a “Permitted Free Writing
Prospectus.”  The Company represents
that it has treated and agrees that it will treat each Permitted Free Writing
Prospectus as an “issuer free writing prospectus,” as defined in Rule 433, and
has complied and will comply with the requirements of Rules 164 and 433
applicable to any Permitted Free Writing Prospectus, including timely
Commission filing where required, legending and record keeping.

(b)  If so indicated in the Subscription
Agreements, the Company will prepare a final term sheet relating to the
Securities, containing only information that describes the final terms of the
Securities and otherwise in a form consented to by the Placement Agent, and
will file such final term sheet within the period required by Rule
433(d)(5)(ii) following the date such final terms have been established for the
offering of the Securities.  Any such
final term sheet is an Issuer Free Writing Prospectus and a Permitted Free
Writing Prospectus for purposes of this Agreement.  The Company also consents to the use by the
Placement Agent of a free writing prospectus that contains only (i)(x)  information describing the
preliminary terms of the Securities or their offering or (y) information that
describes the final terms of the Securities or their offering and that is
included in the final term sheet of the Company contemplated in the first
sentence of this subsection or (ii) other information that is not “issuer
information,” as defined in Rule 433, it being understood that any such free
writing prospectus referred to in clauses (i) or (ii) above shall not be an
Issuer Free Writing Prospectus for purposes of this Agreement.

Section 5.  Payment of Expenses.  The Company
agrees to pay all costs, fees and expenses incurred in connection with the
performance of its obligations hereunder and in connection with the
transactions contemplated hereby, including without limitation (i) all expenses
incident to the issuance and delivery of the Securities (including all printing
and engraving costs), (ii) all fees and expenses of the registrar and transfer
agent of the Common Stock and the Warrants, (iii) all necessary issue, transfer
and other stamp taxes in connection with the issuance and sale of the
Securities to the Purchasers, (iv) all fees and expenses of the Company’s
counsel, independent public or certified public accountants and other advisors,

printing, filing, shipping and distribution of each Registration Statement (including
financial statements, exhibits, schedules, consents and certificates of
experts), each Statutory Prospectus and the Prospectus, and all amendments and
supplements thereto, and this Agreement, (vi) all filing fees, attorneys’ fees
and expenses incurred by the Company in connection with qualifying or
registering (or obtaining 

 12
 

exemptions from the qualification or registration of) all or any part
of the Securities for offer and sale under the state securities or blue sky
laws, and, if requested by the Placement Agent, preparing and printing a “Blue
Sky Survey” or memorandum, and any supplements thereto, advising the Placement
Agent of such qualifications, registrations and exemptions, provided that the
Placement Agent shall consult with the Company prior to incurring any such
costs (vii) the fees and
expenses associated with listing of the Total Shares on the Stock Exchange, if
any, (viii) the escrow agent fees due pursuant to the Escrow Agreement,
and (ix) all other fees, costs and expenses referred to in
Item 14 of Part II of the Registration Statement

Section 6.  Conditions of the Obligations of
the Placement Agent.  The obligations of the Placement Agent
hereunder shall be subject to the accuracy of the representations and
warranties on the part of the Company set forth in Section 2 hereof as of the
date hereof and as of the Closing Date as though then made and the accuracy of
the statements of the Company made in any certificates pursuant to the
provisions hereof, to the timely performance by the Company of its covenants
and other obligations hereunder, and to each of the following additional
conditions:

(a)           On or prior to the date of the Subscription
Agreements, the Placement Agent shall have received a letter, dated the date of
delivery thereof, of Ehrhardt Keefe Steiner & Hottman P.C. substantially in
the form of Exhibit B-1 hereto.

(b)  On or prior to the date of the Subscription
Agreements, the Placement Agent shall have received a letter, dated the date of
delivery thereof, of KPMG LLP substantially in the form of Exhibit B-2
hereto.

(c)    The Prospectus shall have been
filed with the Commission in accordance with the Rules and Regulations and
Section 4(a) of this Agreement.  No
stop order suspending the effectiveness of the Registration Statement or of any
part thereof shall have been issued and no proceedings for that purpose shall
have been instituted or, to the knowledge of the Company or the Placement
Agent, shall be contemplated by the Commission.

(d)  Subsequent to the execution of the Subscription
Agreements, there shall not have occurred (i) any change, or any
development or event involving a prospective change, in the condition
(financial or other), business, properties or results of operations of the
Company and its subsidiaries taken as one enterprise which, in the judgment of
the Placement Agent, is material and adverse and makes it impractical or
inadvisable to proceed with completion of the sale of and payment for by the
Purchasers of the Securities; (ii) any downgrading in the rating of any
debt securities of the Company by any “nationally recognized statistical rating
organization” (as defined for purposes of Rule 436(g) under the Securities
Act), or any public announcement that any such organiza­tion has under
surveillance or review its rating of any debt securities of the Company (other
than an announcement with positive impli­cations of a possible upgrading, and
no implication of a possible down­grading, of such rating) or any announcement
that the Company has been placed on negative outlook; (iii) any change in
U.S. or international financial, political or economic conditions or currency
exchange rates or exchange controls as would, in the judgment of the Placement
Agent, be likely to prejudice materially the success of the proposed issue,
sale or disposition of the Securities 

 13
 

in the secondary market; (iv) any material
suspension or material limitation of trading in securities generally on either
the New York Stock Exchange or the Stock Exchange, or any setting of minimum
prices for trading on such exchange; (v) or any suspension of trading of any
securities of the Company on any exchange or in the over-the-counter market;
(vi) any banking moratorium declared by U.S. Federal or New York
authorities; (vii) any major disruption of settlements of securities or
clearance services in the United States or (viii) any attack on, outbreak
or escalation of hostilities or act of terrorism involving the United States,
any declaration of war by Congress or any other national or international
calamity or emergency if, in the judgment of the Placement Agent, the effect of
any such attack, outbreak, escalation, act, declaration, calamity or emergency
makes it impractical or inadvisable to proceed with the sale of and payment by
the Purchasers for the Securities.

(e)  The Placement Agent shall have received an
opinion, dated the Closing Date, of Latham & Watkins LLP, counsel for the
Company, to the effect that:

(i)            Based on certificates from public officials, the
Company is qualified to do business in California;

(ii)           Based solely on a certificate of an officer of the
Company as to factual matters and a review of a list of specified agreements
attached as an exhibit to such opinion (the “Specified Agreements”), the
Company is not a party to any agreement that would require the inclusion in
either Registration Statement of Common Stock or other securities owned by any
person or entity other than the Company, other than such Specified Agreements
for which the Company has a written waiver from the other party to such
agreement waiving its rights to require the inclusion of its Common Stock or
other securities in each Registration Statement;

(iii)          The Company is not, and immediately after giving
effect to the sale of the Securities in accordance with the Subscription
Agreements and the application of the proceeds as described in the General
Disclosure Package and in the Prospectus under the caption “Use of Proceeds,”
will not be required to be, registered as an “investment company” within the
meaning of the Investment Company Act of 1940, as amended;

(iv)           The execution and delivery of the this Agreement,
the Warrants, the Escrow Agreement and the Subscription Agreements and the
issuance and sale of the Securities by the Company to the Purchasers pursuant to
the Subscription Agreements on the date hereof do not:

(A)          result in the breach of or a default
under any of the Specified Agreements; or

(B)           violate any federal or New York
statute, rule or regulation applicable to the Company; or

(C)           require any consents, approvals, or
authorizations to be obtained by the Company from, or any registrations,
declarations or filings to be 

 14
 

made by the Company with, any governmental
authority under any federal or New York statute, rule or regulation applicable
to the Company that have not been obtained or made;

(v)           The Registration Statements have become effective
under the Securities Act.  Based solely
on a telephonic confirmation by a member of the Staff of the Commission on the
Closing Date, such counsel confirms that no stop order suspending the
effectiveness of the Registration Statement, or any part thereof, has been
issued under the Securities Act and no proceedings therefor have been initiated
or are pending by the Commission.  Any
required filing of the Prospectus pursuant to Rule 424 under the Securities Act
has been made in accordance with Rule 424 under the Securities Act;

(vi)          Each Registration Statement, as of the date of the
Prospectus, and the Prospectus, as of its date, appeared on their face to be
appropriately responsive in all material respects to the requirements for
registration statements on Form S-3 under the Securities Act and the rules and
regulations of the Commission thereunder; it being understood, however, that
such counsel expresses no opinion with respect to Regulation S-T or the
financial statements, schedules, or other financial data, included in,
incorporated by reference in, or omitted from, the Registration Statement or
the Prospectus.  For purposes of this
paragraph, such counsel may assume that the statements made in each
Registration Statement and the Prospectus are correct and complete;

(vii)         Based solely upon a certificate of an officer of the
Company as to factual matters, there are no contracts or documents of a
character required to be described in the Registration Statements or Prospectus
or to be filed as exhibits to the Registration Statements that are not
described or filed;

(viii)        The statements in the Prospectus
under the caption “Description of the Warrants” are accurate in all material
respects;

(ix)           Based on the participation, review and reliance as
described by such counsel in the letter it delivers to the Placement Agent,
such counsel shall advise the Placement Agent that no facts came to their
attention that caused them to believe that:

(A)  the Registration Statements, on the date of
the Prospectus, including the information deemed to be a part of the applicable
Registration Statement pursuant to Rule 430B under the Securities Act (together
with the incorporated documents at that time), contained an untrue statement of
a material fact or omitted to state a material fact required to be stated
therein or necessary to make the statements therein not misleading;

(B)  the Statutory Prospectus, as of the
Applicable Time (together with the incorporated documents at that date), when
taken together with the pricing information listed in Annex A to such letter,
contained an untrue statement of a material fact or omitted to state a material
fact necessary to make the statements therein, in the light of the
circumstances under which they were made, not misleading; or

 15
 

(C)  the Prospectus, as of its date or as of the
date hereof, (together with the incorporated documents at that those dates),
contained or contains an untrue statement of a material fact or omitted or
omits to state a material fact necessary to make the statements therein, in the
light of the circumstances under which they were made, not misleading;

it
being understood that such counsel need not express a belief with respect to
the financial statements, schedules, or other financial data included or
incorporated by reference in, or omitted from, the Registration Statements, any
Statutory Prospectus, the pricing information listed in Annex A to such counsel’s
letter, the Prospectus, or the Incorporated Documents.

(f)  The Placement Agent shall
have received an opinion, dated the Closing Date, of Holland & Hart LLP,
counsel for the Company, to the effect that:

incorporated and is an existing corporation in good standing under the laws of

(v)           The statements in the Prospectus under the captions

 16
 

to the extent
that they purport to describe or summarize certain provisions of the Articles
of Incorporation or Bylaws or Colorado law referred to therein, are accurate

(vi)          The execution, delivery and performance of this

 18
 

Section 8.  Indemnification and
Contribution.  (a) The Company will indemnify and
hold harmless the Placement Agent, its partners, members, directors, officers
and its affiliates and each person, if any, who controls the Placement Agent
within the meaning of Section 15 of the Securities Act, (collectively, the “Placement
Agent Indemnified Parties”) against any losses, claims, damages or liabilities,
joint or several, to which the Placement Agent may become subject, under the
Securities Act or otherwise, insofar as such losses, claims, damages or
liabilities (or actions in respect thereof) arise out of or are based upon any untrue
statement or alleged untrue statement of any material fact contained in the
Registration Statements at any time, any Statutory Prospectus at any time, the
Prospectus or any Issuer Free Writing Prospectus, or arise out of or are based
upon the omission or alleged omission to state therein a material fact required
to be stated therein or necessary to make the statements therein not
misleading, and will reimburse the Placement Agent for any legal or other
out-of-pocket expenses reasonably incurred by the Placement Agent in connection
with investigating or defending any such loss, claim, damage, liability or
action as such expenses are incurred; provided, however, that the Company will
not be liable in any such case to the extent that any such loss, claim, damage
or liability arises out of or is based upon an untrue statement or alleged
untrue statement in or omission or alleged omission from any of such documents
in reliance upon and in conformity with written information furnished to the
Company by the Placement Agent through the Placement Agent, if any,
specifically for use therein, it being understood and agreed that the only such
information furnished by the Placement Agent consists of the Furnished
Information.

(b)           The Placement Agent will indemnify and
hold harmless the Company, its directors and officers and each person, if any,
who controls the Company within the meaning of Section 15 of the Act
(collectively, the “Company Indemnified Parties” and together with the
Placement Agent Indemnified Parties, the “Indemnified Parties”) , against any
losses, claims, damages or liabilities to which the Company may become subject,
under the Act or otherwise, insofar as such losses, claims, damages or
liabilities (or actions in respect thereof) arise out of or are based upon any
untrue statement or alleged untrue statement of any material fact contained in
the Registration Statement at any time, any Statutory Prospectus at any time,
the Prospectus or any Issuer Free Writing Prospectus, or arise out of or are based
upon the omission or the alleged omission to state therein a material fact
required to be stated therein or necessary to make the statements therein not
misleading, in each case to the extent, but only to the extent, that such
untrue statement or alleged untrue statement or omission or alleged omission
was made in reliance upon and in conformity with written information, if any,
furnished to the Company by the Placement Agent specifically for use therein,
and will reimburse any legal or other out-of-pocket expenses reasonably
incurred by the Company in connection with investigating or defending any such
loss, claim, damage, liability or action as such expenses are incurred, it
being understood and agreed that the only such information furnished by the Placement
Agent consists of the Furnished Information.

(c)           Promptly after receipt by an Indemnified
Party under this Section of notice of the commencement of any action, such Indemnified
Party will, if a claim in respect thereof is to be made against the indemnifying
party under subsection (a) or (b) above, notify the indemnifying party of the
commencement thereof; but the failure to
notify the indemnifying party shall not relieve it from any liability that it
may have under subsection (a) or (b) above except to the extent that it has
been materially prejudiced by such failure; and provided further that the
failure to notify the indemnifying party shall not relieve it from any
liability that it may have to an 

 19
 

Indemnified Party otherwise than under subsection (a) or
(b) above.  In case any such action is
brought against any Indemnified Party and it notifies the indemnifying party of
the commencement thereof, the indemnifying party will be entitled to
participate therein and, to the extent that it may wish, jointly with any other
indemnifying party similarly notified, to assume the defense thereof, with
counsel satisfactory to such Indemnified Party (who shall not, except with the
consent of the Indemnified Party, be counsel to the indemnifying party), and
after notice from the indemnifying party to such Indemnified Party of its
election so to assume the defense thereof, the indemnifying party will not be
liable to such Indemnified Party under this Section for any legal or other
expenses subsequently incurred by such Indemnified Party in connection with the
defense thereof other than reasonable costs of investigation.  No indemnifying party shall, without the
prior written consent of the Indemnified Party, effect any settlement of any
pending or threatened action in respect of which any Indemnified Party is or
could have been a party and indemnity could have been sought hereunder by such Indemnified
Party unless such settlement (i) includes an unconditional release of such Indemnified
Party from all liability on any claims that are the subject matter of such
action and (ii) does not include a statement as to, or an admission of, fault,
culpability or a failure to act by or behalf of an Indemnified Party.

(d)           If the indemnification provided for
in this Section is unavailable or insufficient to hold harmless an Indemnified
Party under subsection (a) or (b) above, then each indemnifying party shall
contribute to the amount paid or payable by such Indemnified Party as a result
of the losses, claims, damages or liabilities referred to in subsection (a) or
(b) above (i) in such proportion as is appropriate to reflect the relative
benefits received by the Company on the one hand and the Placement Agent on the
other from the offering of the Securities or (ii) if the allocation provided by
clause (i) above is not permitted by applicable law, in such proportion as is
appropriate to reflect not only the relative benefits referred to in clause (i)
above but also the relative fault of the Company on the one hand and the
Placement Agent on the other in connection with the statements or omissions
which resulted in such losses, claims, damages or liabilities as well as any
other relevant equitable considerations. 
The relative benefits received by the Company on the one hand and the
Placement Agent 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 Company bear to the total underwriting discounts and commissions
received by the Placement Agent.  The
relative fault shall be determined by reference to, among other things, whether
the untrue or alleged untrue statement of a material fact or the omission or
alleged omission to state a material fact relates to information supplied by
the Company or the Placement Agent and the parties’ relative intent, knowledge,
access to informa­tion and opportunity to correct or prevent such untrue
statement or omission.  The amount paid
by an Indemnified Party as a result of the losses, claims, damages or liabilities
referred to in the first sentence of this subsection (d) shall be deemed to
include any legal or other expenses reasonably incurred by such Indemnified
Party in connection with investigating or defending any action or claim which
is the subject of this subsection (d). 
Notwithstanding the provisions of this subsection (d), the Placement
Agent shall not be required to contribute any amount in excess of the placement
agent fees received by the Placement Agent in connection with the
Offering.  No person guilty of fraudulent
misrepresentation (within the meaning of Section 11(f) of the Securities Act)
shall be entitled to contribution from any person who was not guilty of such
fraudulent misrepresentation.

 20
 

(e)           The obligations of the Company under
this Section shall be in addition to any liability which the Company may
otherwise have and shall extend, upon the same terms and conditions, to each
person, if any, who controls the Placement Agent within the meaning of the
Securities Act; and the obligations of the Placement Agent under this Section
shall be in addition to any liability which the Placement Agent may otherwise
have and shall extend, upon the same terms and conditions, to each director of
the Company, to each officer of the Company who has signed the Registration
Statements and to each person, if any, who controls the Company within the
meaning of the Securities Act.

Section
9.  Termination;
Survival of Certain Representations and Obligations.   If any condition specified in Section 6 is
not satisfied when and as required to be satisfied, when and as required to be
satisfied, this Agreement may be terminated by the Placement Agent by notice to
the Company at any time on or prior to the Closing Date.  The Company may terminate this Agreement at
any time prior to execution of a Subscription Agreement upon written notice to
the Placement Agent.  Any termination
pursuant to this Section 9 shall be without liability on the part of any party
to any other party, except that Section 5, Section 7, Section 8, Section 
9, Section 10 and Section 11 shall at all times be effective and
shall survive such termination. The respective indemnities, agreements,
representations, warranties and other statements of the Company or its officers
and of the Placement Agent set forth in or made pursuant to this Agreement will
remain in full force and effect, regardless of any investigation, or statement
as to the results thereof, made by or on behalf of the Placement Agent, the
Company or any of their respective representatives, officers or directors or
any controlling person, and will survive delivery of and payment for the
Securities.  If for any reason the
purchase of the Securities by the Placement Agent is not consummated, the
Company shall remain responsible for the expenses to be paid or reimbursed by
it pursuant to Section 5 or Section 7 and the respective rights and obligations
of the Company and the Placement Agent pursuant to Section 8 shall remain in
effect.

legally unenforceable.

4.4                   The Purchaser understands
