          Environmental Laws, failure to receive required permits, licenses or

               (xiii) such counsel (A) is of the opinion that the Registration
          Statement and Prospectus (except for financial statements and

          express any belief) the Registration Statement and the prospectus
          included therein at the time the Registration Statement became

          material fact or omits to state a material fact necessary in order to
          make the statements therein, in the light of the circumstances under
          which they were made, not misleading.

          (d)  The Underwriters shall have received on the Closing Date an
     opinion of Bozicevic, Field & Francis LLP, patent counsel to the Company,
     dated the Closing Date, with respect to certain patent matters, to the
     effect that:

               (i) The Company owns or has valid licenses to use all patents,
          licenses, inventions and rights described in the Prospectus as being
          owned or licensed by it, and such counsel is not aware of any claim to
          the contrary or any

                                       11


          challenge by any other person to the rights of the Company with
          respect to the foregoing other than those identified in the
          Prospectus;

               (ii)  Such counsel is not aware of any legal actions, claims or
          proceedings pending or threatened against the Company, its
          manufacturers, suppliers or customers other than those identified in
          the Prospectus alleging that the Company is infringing or otherwise
          violating any patents, licenses or inventions owned by others;

               (iii) Such counsel has reviewed the descriptions of intellectual
          property under the captions "Risk Factors - Our agreement with ALZA
          limits our fields of operation for our DUROS-based pharmaceutical
          systems, requires us to spend significant funds on product development
          and gives ALZA a first right to distribute selected products for us,"
          "Business - Development and Commercialization Agreement with ALZA
          Corporation" and "- Patents, Licenses and Proprietary Rights" in the
          Registration Statement and Prospectus, and, to the extent they
          constitute matters of law or legal conclusions, these descriptions are
          accurate and fairly and completely present the patent situation of the
          Company or that such descriptions contain any untrue statement of a
          material fact or omit to state a material fact necessary to make the
          statements made therein, in light of the circumstances under which
          they were made, not misleading, including without limitation, any
          undisclosed material issue with respect to the subsequent validity or
          enforceability of such patent or patent issuing from any such pending
          patent application.

               (iv)  With respect to the patent protection on the Company's
          technology for each patent or patent application described in the
          Prospectus as being owned by the Company, such counsel is aware of
          nothing that causes such counsel to believe that, as of the date the
          Registration Statement became effective and as of the date of such
          opinion, the description of patents and patent applications under the
          captions "Risk Factors--If we are unable to adequately protect or
          enforce our intellectual property rights or secure rights to third-
          party patents, we may lose valuable assets, experience reduced market
          share or incur costly litigation to protect our rights," and "Business
          - Intellectual Property" in the Registration Statement and Prospectus
          contain any untrue statement of a material fact or omit to state a
          material fact necessary to make the statements made therein, in light
          of the circumstances under which they were made, not misleading,
          including without limitation, any undisclosed material issue with
          respect to the subsequent validity or enforceability of such patent or
          patent issuing from any such pending patent application.

          (e)  The Underwriters shall have received on the Closing Date an
     opinion of ________________________, Food and Drug Administration ("FDA")
     counsel to the Company, dated the closing date, with respect to certain FDA
     matters, to the effect that:

               (i) The statements in the Prospectus under the captions "Risk
          Factors - We must conduct and satisfactorily complete clinical trials
          for our

                                       12


          pharmaceutical systems," "- Failure to obtain product approvals or
          comply with ongoing governmental regulations could delay or limit
          introduction of our new products and result in failure to achieve
          anticipated revenues," "Business - Durect Pharmaceutical Systems
          Technology," "- Product Development Programs," and "-Government
          Regulation," insofar as such statements constitute legal conclusions
          under the Federal Food, Drug, and Cosmetic Act ("FDC Act"), the Public
          Health Service Act ("PHS Act") or the FDA regulations (such matters
          (a) and (b) collectively, the "FDA Regulatory Matters"), regulations
          or summaries of FDA Regulatory Matters, have been reviewed by such
          counsel and fairly present and summarize, in all material respects,
          the matters referred to therein.

               (ii)  Such counsel knows of no material action, suit, claim or
          proceeding relating to FDA Regulatory Matters which is pending or
          threatened against the Company or any of its officers or directors,
          nor is such counsel aware of any material violation of the FDC Act,
          the PHS Act or FDA regulations by the Company.

               (iii) The Company has filed the Investigational New Drug ("IND")
          applications and New Drug Approval ("NDA") applications with the FDA
          listed on Schedule 1 (collectively, the "US Applications"). The FDA
                    ----------
          has not denied any of the Company's US Applications. Such counsel is
          not aware of any material defect in form in the preparation or filing
          of the US Applications. To the knowledge of such counsel, the US
          Applications are being diligently pursued by the Company. To the
          knowledge of such counsel, the Company is the sole owner of the US
          Applications.

               (iv)  The FDA has not placed a clinical hold on any Company
          clinical trial, and/or placed any conditions on the continuation of a
          Company clinical trial, and the Company has not voluntarily or
          involuntarily, on a temporary or permanent basis, suspended or
          terminated a clinical trial.

               (v)   To such counsel's knowledge, no Adverse Event has occurred
          during a clinical trial that would require the Company to report such
          event to the FDA.

          (f)  The Underwriters shall have received on the Closing Date an
     opinion of Gray Cary Ware & Freidenrich LLP, counsel for the Underwriters,
     dated the Closing Date, covering the matters referred to in Sections
     5(c)(vi), 5(c)(vii), 5(c)(ix) (but only as to the statements in the
     Prospectus under "Description of Capital Stock" and "Underwriters") and
     5(c)(xiii) above.

          With respect to Section 5(c)(xiii) above, Venture Law Group and Gray
     Cary Ware & Freidenrich LLP may state that their opinion and belief are
     based upon their participation in the preparation of the Registration
     Statement and Prospectus and any amendments or supplements thereto and
     review and discussion of the contents thereof, but are without independent
     check or verification, except as specified.

                                       13


          The opinions of Venture Law Group, Bozicevic, Field & Francis LLP and
     _____________ described in Sections 5(c), 5(d) and 5(e) above shall be
     rendered to the Underwriters at the request of the Company and shall so
     state therein.

          (g)  The Underwriters shall have received, on each of the date hereof
     and the Closing Date, a letter dated the date hereof or the Closing Date,
     as the case may be, in form and substance satisfactory to the Underwriters,
     from Ernst & Young LLP, independent public accountants, containing
     statements and information of the type ordinarily included in accountants'
     "comfort letters" to underwriters with respect to the financial statements
     and certain financial information contained in the Registration Statement
     and the Prospectus; provided that the letter delivered on the Closing Date
     shall use a "cut-off date" not earlier than the date hereof.

          (h)  The "lock-up" agreements, each substantially in the form of
     Exhibit A hereto, between you and certain shareholders, officers and
     directors of the Company relating to sales and certain other dispositions
     of shares of Common Stock or certain other securities, delivered to you on
     or before the date hereof, shall be in full force and effect on the Closing
     Date.

          The several obligations of the Underwriters to purchase Additional
Shares hereunder are subject to the delivery to the Representatives on the
Option Closing Date of such documents as they may reasonably request with
respect to the good standing of the Company, the due authorization and issuance
of the Additional Shares and other matters related to the issuance of the
Additional Shares.

     6.   Covenants of the Company. In further consideration of the agreements
of the Underwriters herein contained, the Company covenants with each
Underwriter as follows:

          (c)  If, during such period after the first date of the public
     offering of the Shares as in the opinion of counsel for the Underwriters
     the Prospectus is required by law to be delivered in connection with sales
     by an Underwriter or dealer, any event shall occur or condition exist as a
     result of which it is necessary to amend or supplement the Prospectus in
     order to make the statements therein, in the light of the circumstances
     when

                                       14


     the Prospectus is delivered to a purchaser, not misleading, or if, in the

     supplement the Prospectus to comply with applicable law, forthwith to
     prepare, file with the Commission and furnish, at its own expense, to the
     Underwriters and to the dealers (whose names and addresses you will furnish

     Underwriters and to any other dealers upon request, either amendments or
     supplements to the Prospectus so that the statements in the Prospectus as
     so amended or supplemented will not, in the light of the circumstances when
     the Prospectus is delivered to a purchaser, be misleading or so that the
     Prospectus, as amended or supplemented, will comply with law.

     for a period of three years after the date hereof or until such earlier
     date as the Shares shall be listed for regular trading privileges on
     another national securities exchange approved by you.

          (h)  The Company will comply with all registration, filing and
     reporting requirements of the Exchange Act which may from time to time be

     expressly for use therein.

          (b)  Each Underwriter agrees, severally and not jointly, to indemnify
     and hold harmless the Company, its directors, its officers who sign the
     Registration Statement and each person, if any, who controls the Company
     within the meaning of either Section 15 of the Securities Act or Section 20
     of the Exchange Act to the same extent as the foregoing indemnity from the
     Company to such Underwriter, but only with reference to information
     relating to such Underwriter furnished to the Company in writing by such
     Underwriter through you expressly for use in the Registration Statement,
     any preliminary prospectus, the Prospectus or any amendments or supplements
     thereto.

          (c)  In case any proceeding (including any governmental investigation)
     shall be instituted involving any person in respect of which indemnity may
     be sought pursuant to Section 7(a) or 7(b), such person (the "indemnified
     party") shall promptly notify the person against whom such indemnity may be
     sought (the "indemnifying party") in writing and the indemnifying party,
     upon request of the indemnified party, shall retain counsel reasonably
     satisfactory to the indemnified party to represent the indemnified party
     and any others the indemnifying party may designate in such proceeding and
     shall pay the fees and disbursements of such counsel related to such
     proceeding. In any such proceeding, any indemnified party shall have the
     right to retain its own counsel, but the fees and expenses of such counsel
     shall be at the expense of such indemnified party unless (i) the
     indemnifying party and the indemnified party shall have mutually agreed to
     the retention of such counsel or (ii) the named parties to any such
     proceeding (including any impleaded parties) include both the indemnifying
     party and the indemnified party and representation of both parties by the
     same counsel would be inappropriate due to actual or potential differing
     interests between them. It is understood that the indemnifying party shall
     not, in respect of the legal expenses of any indemnified party in
     connection with any proceeding or related proceedings in the same
     jurisdiction, be liable for the fees and expenses of more than one separate
     firm (in addition to any local counsel) for all such indemnified parties
     and that all such fees and expenses shall be reimbursed as they are
     incurred. Such firm shall be designated in writing by Morgan Stanley & Co.
     Incorporated, in the case of parties indemnified pursuant to Section 7(a),
     and by the Company, in the case of parties indemnified pursuant to Section
     7(b). The indemnifying party shall not be liable for any settlement of any
     proceeding effected without its written consent, but if settled with such
     consent or if there be a final judgment for the plaintiff, the indemnifying
     party agrees to indemnify the indemnified party from and against any loss
     or liability by reason of such settlement or judgment. Notwithstanding the
     foregoing sentence, if at any time an indemnified party shall have
     requested an indemnifying party to reimburse the indemnified party for fees
     and expenses of counsel as contemplated by the second and third sentences
     of this paragraph, the indemnifying party agrees that it shall be liable
     for any settlement of any proceeding effected without its written consent
     if (i) such settlement is entered into more than 30 days after receipt by
     such indemnifying party of the aforesaid request and (ii) such indemnifying
     party shall not have reimbursed the indemnified party in accordance with
     such request prior to the date of such settlement. No indemnifying party
     shall, without the prior written consent of the indemnified party, effect
     any settlement of any pending or threatened proceeding in

                                       17


     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 includes an unconditional release of such
     indemnified party from all liability on claims that are the subject matter
     of such proceeding.

          (d)  To the extent the indemnification provided for in Section 7(a) or
     7(b) is unavailable to an indemnified party or insufficient in respect of
     any losses, claims, damages or liabilities referred to therein, then each
     indemnifying party under such paragraph, in lieu of indemnifying such
     indemnified party thereunder, shall contribute to the amount paid or
     payable by such indemnified party as a result of such losses, claims,
     damages or liabilities (i) in such proportion as is appropriate to reflect
     the relative benefits received by the Company on the one hand and the
     Underwriters on the other hand from the offering of the Shares or (ii) if
     the allocation provided by clause 7(d)(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 7(d)(i) above but also the
     relative fault of the Company on the one hand and of the Underwriters on
     the other hand in connection with the statements or omissions that 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 Underwriters on the other hand in
     connection with the offering of the Shares shall be deemed to be in the
     same respective proportions as the net proceeds from the offering of the
     Shares (before deducting expenses) received by the Company and the total
     underwriting discounts and commissions received by the Underwriters, in
     each case as set forth in the table on the cover of the Prospectus, bear to
     the aggregate Public Offering Price of the Shares. The relative fault of
     the Company on the one hand and the Underwriters on the other hand 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 by the Underwriters and the parties' relative intent, knowledge,
     access to information and opportunity to correct or prevent such statement
     or omission. The Underwriters' respective obligations to contribute
     pursuant to this Section 7 are several in proportion to the respective
     number of Shares they have purchased hereunder, and not joint.

          (e)  The Company and the Underwriters agree that it would not be just
     or equitable if contribution pursuant to this Section 7 were determined by
     pro rata allocation (even if the Underwriters were treated as one entity
     for such purpose) or by any other method of allocation that does not take
     account of the equitable considerations referred to in Section 7(d). The
     amount paid or payable by an indemnified party as a result of the losses,
     claims, damages and liabilities referred to in the immediately preceding
     paragraph shall be deemed to include, subject to the limitations set forth
     above, 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 7, no Underwriter
     shall be required to contribute any amount in excess of the amount by which
     the total price at which the Shares underwritten by it and distributed to
     the public were offered to the public exceeds the amount of any damages
     that such Underwriter has otherwise been required to pay by reason of such
     untrue or alleged untrue statement or omission or alleged omission. No
     person guilty of fraudulent

                                       18


     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. The remedies provided for in this
     Section 7 are not exclusive and shall not limit any rights or remedies
     which may otherwise be available to any indemnified party at law or in
     equity.

          (f)  The indemnity and contribution provisions contained in this
     Section 7 and the representations, warranties and other statements of the
     Company contained in this Agreement shall remain operative and in full
     force and effect regardless of (i) any termination of this Agreement, (ii)
     any investigation made by or on behalf of any Underwriter or any person
     controlling any Underwriter or by or on behalf of the Company, its officers
     or directors or any person controlling the Company and (iii) acceptance of
     and payment for any of the Shares.

     8.   Directed Share Program Indemnification.

          (a)  The Company agrees to indemnify and hold harmless Morgan Stanley
     and its affiliates and each person, if any, who controls Morgan Stanley or
     its affiliates within the meaning of either Section 15 of the Securities
     Act or Section 20 of the Exchange Act ("Morgan Stanley Entities"), from and
     against any and all losses, claims, damages and liabilities (including,
     without limitation, any legal or other expenses reasonably incurred in
     connection with defending or investigating any such action or claim) (i)
     caused by any untrue statement or alleged untrue statement of a material
     fact contained in any material prepared by or with the consent of the
     Company for distribution to Participants in connection with the Directed
     Share Program, or caused by any omission or alleged omission to state
     therein a material fact required to be stated therein or necessary to make
     the statements therein not misleading; (ii) caused by the failure of any
     Participant to pay for and accept delivery of Directed Shares that the
     Participant has agreed to purchase; or (iii) related to, arising out of, or
     in connection with the Directed Share Program other than losses, claims,
     damages or liabilities (or expenses relating thereto) that are finally
     judicially determined to have resulted from the bad faith or gross
     negligence of Morgan Stanley Entities.

          (b)  In case any proceeding (including any governmental investigation)
     shall be instituted involving any Morgan Stanley Entity in respect of which
     indemnity may be sought pursuant to Section 7(a), the Morgan Stanley Entity
     seeking indemnity shall promptly notify the Company in writing and the
     Company, upon request of the Morgan Stanley Entity, shall retain counsel
     reasonably satisfactory to the Morgan Stanley Entity to represent the
     Morgan Stanley Entity and any other the Company may designate in such
     proceeding and shall pay the fees and disbursements of such counsel related
     to such proceeding. In any such proceeding, any Morgan Stanley Entity shall
     have the right to retain its own counsel, but the fees and expenses of such
     counsel shall be at the expense of such Morgan Stanley Entity unless (I)
     the Company shall have agreed to the retention of such counsel or (ii) the
     named parties to any such proceeding (including any impleaded parties)
     include both the Company and the Morgan Stanley Entity and representation
     of both parties by the same counsel would be inappropriate due to actual or
     potential differing interests between them. The Company shall not, in
     respect of the legal

                                       19


     expenses of the Morgan Stanley Entities in connection with any proceeding
     or related proceedings the same jurisdiction, be liable for the fees and
     expenses of more than one separate firm (in addition to any local counsel)
     for all Morgan Stanley Entities. Any such firm for the Morgan Stanley
     Entities shall be designated in writing by Morgan Stanley. The Company
     shall not be liable for any settlement of any proceeding effected without
     its written consent, but if settled with such consent or if there be a
     final judgment for the plaintiff, the Company agrees to indemnify the
     Morgan Stanley Entities from and against any loss or liability by reason of
     such settlement or judgment. Notwithstanding the foregoing sentence, if at
     any time a Morgan Stanley Entity shall have requested the Company to
     reimburse it for fees and expenses of counsel as contemplated by the second
     and third sentences of this paragraph, the Company agrees that it shall be
     liable for any settlement of any proceeding effected without its written
     consent if (i) such settlement is entered into more than 30 days after
     receipt by the Company of the aforesaid request and (ii) the Company shall
     not have reimbursed the Morgan Stanley Entity in accordance with such
     request prior to the date of such settlement. The Company shall not,
     without the prior written consent of Morgan Stanley, effect any settlement
     of any pending or threatened proceeding in respect of which any Morgan
     Stanley Entity is or could have been a party and indemnity could have been
     sought hereunder by such Morgan Stanley Entity, unless such settlement
     includes an unconditional release of the Morgan Stanley Entities from all
     liability on claims that are the subject matter of such proceeding.

          (c)  To the extent the indemnification provided for in Section 7(a) is
     unavailable to a Morgan Stanley Entity or insufficient in respect of any
     losses, claims, damages or liabilities referred to therein, then the
     Company, in lieu of indemnifying the Morgan Stanley Entity thereunder,
     shall contribute to the amount paid or payable by the Morgan Stanley Entity
     as a result of such losses, claims, damages or liabilities (i) in such
     proportion as is appropriate to reflect the relative benefits received by
     the Company on the one hand and the Morgan Stanley Entities on the other
     hand from the offering of the Directed Shares or (ii) if the allocation
     provided by clause 7(c)(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 7(c)(i) above but also the relative fault of the
     Company on the one hand and of the Morgan Stanley Entities on the other
     hand in connection with the statements or omissions that 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 of the Morgan Stanley Entities on the other hand in
     connection with the offering of the Directed Shares shall be deemed to be
     in the same respective proportions as the net proceeds from the offering of
     the Directed Shares (before deducting expenses) and the total underwriting
     discounts and commissions received by the Morgan Stanley Entities for the
     Directed Shares, bear to the aggregate Public Offering Price of the Shares.
     If the loss, claim, damage or liability is caused by an untrue or alleged
     untrue statement of a material fact, the relative fault of the Company on
     the one hand and the Morgan Stanley Entities on the other hand shall be
     determined by reference to, among other things, whether the untrue or
     alleged untrue statement or the omission or alleged omission relates to
     information supplied by the Company or by the Morgan Stanley Entities and
     the parties' relative intent, knowledge, access to information and
     opportunity to correct or prevent such statement or omission.

                                       20


          (d)  The Company and the Morgan Stanley Entities agree that it would
     not be just or equitable if contribution pursuant to this Section 8 were
     determined by pro rata allocation (even if the Morgan Stanley Entities were
     treated as one entity for such purpose) or by any other method of
     allocation that does not take account of the equitable considerations
     referred to in Section 8(c). The amount paid or payable by the Morgan
     Stanley Entities as a result of the losses, claims, damages and liabilities
     referred to in the immediately preceding paragraph shall be deemed to
     include, subject to the limitations set forth above, any legal or other
     expenses reasonably incurred by the Morgan Stanley Entities in connection
     with investigating or defending any such action or claim. Notwithstanding
     the provisions of this Section 8, no Morgan Stanley Entity shall be
     required to contribute any amount in excess of the amount by which the
     total price at which the Directed Shares distributed to the public were
     offered to the public exceeds the amount of any damages that such Morgan
     Stanley Entity has otherwise been required to pay by reason of such untrue
     or alleged untrue statement or omission or alleged omission. The remedies
     provided for in this Section 8 are not exclusive and shall not limit any
     rights or remedies which may otherwise be available to any Morgan Stanley
     Entity at law or in equity.

          (e)  The indemnity and contribution provisions contained in this
     Section 8 shall remain operative and in full force and effect regardless of
     (i) any termination of this Agreement, (ii) any investigation made by or on
     behalf of any Morgan Stanley Entity or the Company, its officers or
     directors or any person controlling the Company and (iii) acceptance of and
     payment for any of the Directed Shares.

     9.   Termination. This Agreement shall be subject to termination by notice
given by you to the Company, if (a) after the execution and delivery of this
Agreement and prior to the Closing Date (i) trading generally shall have been
suspended or materially limited on or by, as the case may be, any of the New
York Stock Exchange, the American Stock Exchange, the National Association of
Securities Dealers, Inc., the Chicago Board of Options Exchange, the Chicago
Mercantile Exchange or the Chicago Board of Trade, (ii) trading of any
securities of the Company shall have been suspended on any exchange or in any
over-the-counter market, (iii) a general moratorium on commercial banking
activities in New York shall have been declared by either Federal or New York
State authorities or (iv) there shall have occurred any outbreak or escalation
of hostilities or any change in financial markets or any calamity or crisis
that, in your judgment, is material and adverse and (b) in the case of any of
the events specified in clauses 9(a)(i) through 9(a)(iv), such event, singly or
together with any other such event, makes it, in your judgment, impracticable to
market the Shares on the terms and in the manner contemplated in the Prospectus.

     10.  Effectiveness; Defaulting Underwriters. This Agreement shall become
effective upon the execution and delivery hereof by the parties hereto.

     If, on the Closing Date or the Option Closing Date, as the case may be, any
one or more of the Underwriters shall fail or refuse to purchase Shares that it
has or they have agreed to purchase hereunder on such date, and the aggregate
number of Shares which such defaulting Underwriter or Underwriters agreed but
failed or refused to purchase is not more than one-tenth of the aggregate number
of the Shares to be purchased on such date, the other Underwriters shall

                                       21


be obligated severally in the proportions that the number of Firm Shares set
forth opposite their respective names in Schedule I or Schedule II bears to the
aggregate number of Firm Shares set forth opposite the names of all such non-
defaulting Underwriters, or in such other proportions as you may specify, to
purchase the Shares which such defaulting Underwriter or Underwriters agreed but
failed or refused to purchase on such date; provided that in no event shall the
number of Shares that any Underwriter has agreed to purchase pursuant to this
Agreement be increased pursuant to this Section 10 by an amount in excess of
one-ninth of such number of Shares without the written consent of such
Underwriter. If, on the Closing Date, any Underwriter or Underwriters shall fail
or refuse to purchase Firm Shares and the aggregate number of Firm Shares with
respect to which such default occurs is more than one-tenth of the aggregate
number of Firm Shares to be purchased, and arrangements satisfactory to you and
the Company for the purchase of such Firm Shares are not made within 36 hours
after such default, this Agreement shall terminate without liability on the part
of any non-defaulting Underwriter or the Company. In any such case either you or
the Company 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. If, on the Option Closing Date, any Underwriter or
Underwriters shall fail or refuse to purchase Additional Shares and the
aggregate number of Additional Shares with respect to which such default occurs
is more than one-tenth of the aggregate number of Additional Shares to be
purchased, the non-defaulting Underwriters shall have the option to (i)
terminate their obligation hereunder to purchase Additional Shares or (ii)
purchase not less than the number of Additional Shares that such non-defaulting
Underwriters would have been obligated to purchase in the absence of such
default. Any action taken under this paragraph shall not relieve any defaulting
Underwriter from liability in respect of any default of such Underwriter under
this Agreement.

     If this Agreement shall be terminated by the Underwriters, or any of them,
because of any failure or refusal on the part of the Company to comply with the
terms or to fulfill any of the conditions of this Agreement, or if for any
reason the Company shall be unable to perform its obligations under this
Agreement, the Company will reimburse the Underwriters or such Underwriters as
have so terminated this Agreement with respect to themselves, severally, for all
out-of-pocket expenses (including the fees and disbursements of their counsel)
reasonably incurred by such Underwriters in connection with this Agreement or
the offering contemplated hereunder.

     11.  Counterparts. This Agreement may be signed in two or more
counterparts, each of which shall be an original, with the same effect as if the
signatures thereto and hereto were upon the same instrument.

     12.  Applicable Law. This Agreement shall be governed by and construed in
accordance with the internal laws of the State of New York.

                                       22


     13.  Headings. The headings of the sections of this Agreement have been
inserted for convenience of reference only and shall not be deemed a part of
this Agreement.

                                        Very truly yours,
