200,000 Shares

Cypros Pharmaceutical Corporation
Common Stock

      This Prospectus relates to 200,000 shares (the "Shares") of
Common  Stock,  no par value per share (the "Common  Stock"),  of
Cypros Pharmaceutical Corporation (the "Company"). The Shares may
be  offered  by  a  shareholder  of  the  Company  (the  "Selling
Shareholder") from time to time, as market conditions  permit  on
the NASDAQ National Market System, or otherwise, through ordinary
brokerage  transactions,  in negotiated  transactions,  at  fixed
prices  which may be changed, at market prices prevailing at  the
time  of sale, at prices related to such prevailing market prices
or at negotiated prices.  The Selling Shareholder may effect such
transactions  by selling the Shares to or through broker-dealers,
and  all such broker-dealers may receive compensation in the form
of   discounts,  concessions  or  commissions  from  the  Selling
Shareholder  and/or the purchasers of the Shares  for  whom  such
broker-dealers  may  act  as  agent  or  to  whom  they  sell  as
principal, or both (which compensation as to a particular broker-
dealer  might  be  in  excess  of  customary  commissions).   See
"Selling Shareholders" and "Plan of Distribution."

      None  of  the proceeds from the sale of the Shares  by  the
Selling Shareholder will be received by the Company.  The Company
has  agreed  to  bear  certain  expenses  (other  than  fees  and
expenses,  if  any, of counsel or other advisors to  the  Selling
Shareholders) in connection with the registration and sale of the
Shares being offered by the Selling Shareholder.  The Company has
agreed  to  indemnify  the  Selling Shareholder  against  certain
liabilities,  including certain liabilities under the  Securities
Act of 1933, as amended.

                           THE COMPANY

       The  Company  was founded in California  in  1990  and  is
engaged in the development and marketing of drug products for the
hospital   market.  It  is  currently  marketing  two  injectable
products which determine glomerular filtration rates, Glofil  and
Inulin,  and is developing two small molecule therapeutic  drugs,
CPC-111  and  CPC-211  for the treatment of  disorders,  such  as
stroke,  traumatic head injury, congestive heart failure, cardiac
surgery,  sickle  cell  crisis, and the  acute  complications  of
angioplasty, all of which are characterized by ischemia (impaired
blood  flow), which interrupts the delivery of both  glucose  and
oxygen to tissue. The Company's executive offices are located  at
2714  Loker  Avenue  West, Carlsbad, California  92008,  and  its
telephone number is (619) 929-9500.
                                
                          RISK FACTORS

      Except for the historical information contained herein, the
discussion in this Prospectus contains forward-looking statements
that  involve  risks  and  uncertainties.  The  Company's  actual
results  could  differ  materially  from  those  discussed  here.
Factors  that  could  cause  or contribute  to  such  differences
include, but are not limited to, those discussed in the following
risk  factors  as  well  as  those discussed  elsewhere  in  this
Prospectus and any documents incorporated herein by reference.

      The  following  factors,  in addition  to  those  discussed
elsewhere   in  this  Prospectus,  or  incorporated   herein   by
reference,  should  be  carefully considered  in  evaluating  the
Company and its business.

Continuing Operating Losses

      On  August 9, 1995, the Company became an operating company
with  the  acquisition of two Glofil and Inulin,  two  injectable
products  approved by the U.S. Food and Drug Administration  (the
"FDA")  and  reported sales from those products  during  the  six
months  ended January 31, 1996 of $578,718. For that period,  the
Company  reported  a net loss of $1,380,940 or  $0.12  per  share
compared to a loss of $1,462,475 or $0.17 per share for the prior
year  period. The Company expects that it will continue to  incur
operating  losses  as  it  increases  expenditures  for  clinical
testing,  Investigational  New  Drug  Application  and  New  Drug
Application filings and other regulatory activities, U.S.  patent
prosecution,  and  sales  and marketing activities.   To  achieve
profitable  operations, the Company, alone or with  others,  must
successfully develop, obtain regulatory approval for,  introduce,
acquire,  market and sell additional products. There  can  be  no
assurance  that the Company's product acquisition and development
efforts   will  result  in  additional  products,  that  required
regulatory approvals will be obtained with respect to all or  any
of  its  products  now under development or  that  any  of  these
products will be commercially successful.

Significant Capital Requirements; Need for Additional Financing

      The development and commercialization of drugs requires the
commitment  of  significant  capital expenditures.   The  Company
believes  that existing capital resources and the cash flow  from
its  recently-acquired products will allow  it  to  maintain  its
current  and  planned operations for 21 months.  In  addition  to
funds  provided  from  exercises  of  its  currently  outstanding
Redeemable  Class  B Warrants (the "Warrants"),  the  Company  is
seeking  to  obtain  additional funds through public  or  private
equity  financings,  collaborative  or  other  arrangements  with
corporate  partners  or  from other sources.   There  can  be  no
assurance  that  such additional financing  can  be  obtained  on
desirable  terms  or  at  all.   If  additional  funds  are   not
available,  the Company may be required to curtail  significantly
or   eliminate  one  or  more  of  its  research,  discovery   or
development  programs or obtain funds through arrangements  which
may  require the Company to relinquish rights to certain  of  its
products.

Uncertainties Associated with Regulatory Approval

      A  marketed  drug,  its manufacturer and its  manufacturing
facilities   are  subject  to  continual  review   and   periodic
inspections,  and later discovery of previously unknown  problems
with   a   product,  manufacturer  or  facility  may  result   in
restrictions  on  such  product  or  manufacturers,  including  a
withdrawal of the product from the market. Failure to comply with
the  applicable regulatory requirements can, among other  things,
result  in  fines,  suspensions of regulatory approvals,  product
recalls,   operating   restrictions  and  criminal   prosecution.
Further,  additional  government regulation  may  be  established
which  could  suspend  or  revoke  regulatory  approval  of   the
Company's products.

Unproven Products

     In addition to its two approved drugs, the Company has other
products  in various stages of development, which are subject  to
the  risks  inherent  in drug development,  including  unforeseen
problems,   delays,   expenses   and   complications   frequently
encountered  with the early phases of research,  development  and
commercialization of products, the dependence on and attempts  to
apply  new  and  rapidly changing technology and the  competitive
environment  of  the  pharmaceutical  industry.   Many  of  these
factors   may   be   beyond  the  Company's  control,   such   as
unanticipated   development  requirements,  testing,   regulatory
compliance and manufacturing, production, and marketing  problems
and  expenses.  The  Company does not anticipate  being  able  to
complete the development of its proposed products for a number of
years,  if  at  all. All of the Company's drugs  are  subject  to
extensive  regulation  and  those  in  development  will  require
approval  from  the  FDA and other regulatory agencies  prior  to
commercial  sales.  The Company may not complete the testing  and
regulatory   approval  process  for  any  of  its   products   in
development in the foreseeable future and, accordingly, is unable
to   predict   whether  they  will  be  commercially  successful.
Further, there can be no assurance that the Company's drugs under
development  will  attain  acceptance  by  providers,  payors  or
patients.

Patents, Proprietary Technology and Licenses

     The Company's success is dependent in large measure upon its
ability  to  obtain  patent protection for  its  drugs,  maintain
confidentiality  of  its trade secrets and know-how  and  operate
without  infringing upon the proprietary rights of third parties.
The  Company  has licensed rights to five U.S. patents  from  the
holders of the patents on CPC-111 and CPC-211, but each of  these
licenses may be terminated in the event that the Company fails to
achieve   certain   milestones  or   accomplish   certain   other
contractual obligations. Upon any such termination,  all  of  the
Company's rights would revert to the licensor. The termination of
the  license  covering CPC-111 or CPC-211 would have  a  material
adverse  effect  on the Company and would cause  the  Company  to
focus  its  efforts  on  its remaining drug development  programs
which are not as far advanced. There can be no assurance that the
Company  will  maintain  the  licenses  in  effect  through   the
successful development and commercialization of these drugs.

       The  U.S.  patent  position  of  pharmaceutical  companies
involves many complex legal and technical issues and has recently
been  the  subject of much litigation.  There is no clear  policy
establishing  the breadth of claims or the degree  of  protection
afforded  under  such  patents.  As a result,  there  can  be  no
assurance  that  any  of  the U.S. patent  applications  will  be
approved,  except where claims under an application have  already
been  examined  and  allowed, nor that the Company  will  develop
additional proprietary products that are patentable.   There  can
be  no  assurance that any U.S. patents issued to the Company  or
its  licensors  will  provide the Company  with  any  competitive
advantages or will not be challenged by any third parties or that
patents issued to others will not have an adverse effect  on  the
ability of the Company to conduct its business.

      Furthermore,  because  patent applications  in  the  United
States  are  maintained  in  secrecy  until  issue,  and  because
publication   of  discoveries  in  the  scientific   and   patent
literature  often  lag  behind actual  discoveries,  the  Company
cannot  be certain that it was the first chronologically to  make
the inventions covered by each of its pending patent applications
or  that  it was the first to file patent applications  for  such
inventions.   In the event that a third party has  also  filed  a
patent  application for any of its inventions,  the  Company  may
have  to participate in interference proceedings declared by  the
United  States Patent and Trademark Office to determine  priority
of  the invention, which could result in substantial cost to  the
Company,  even  if  the  eventual outcome  is  favorable  to  the
Company.   In  addition,  there can  be  no  assurance  that  the
Company's patents, including those of the licensors above,  would
be  held  valid by a court of law of competent jurisdiction.   If
patents are issued to other companies that contain competitive or
conflicting  claims  which ultimately may  be  determined  to  be
valid,  there can be no assurance that the Company would be  able
to obtain a license to any of these U.S. patents.

      Under Title 35 of the United States Code, as amended by the
General  Agreement on Tariffs and Trade implementing the  Uruguay
Round  Agreement  Act of 1994 ("GATT"), patents that  issue  from
patent applications filed prior to June 8, 1995, will have a  17-
year period of enforceability as measured from the date of patent
issue  while those that issue from applications filed on or after
June  8,  1995  will  have a 20-year period of enforceability  as
measured  from the date the patent application was filed  or  the
first  claimed priority date, whichever is earlier. Patents  that
issue  from applications filed on or after June 8, 1995,  may  be
extended under the term extension provisions of GATT for a period
up  to  five years to compensate for any period of enforceability
lost  due to interference proceedings, government secrecy  orders
or appeals to the Board of Patent Appeals or the Federal Circuit.

     Under the Drug Price Competition and Patent Term Restoration
Act  of  1984, including amendments implemented under  GATT  (the
"Patent Term Restoration Act"), the period of enforceability of a
first  or basic product patent or use patent covering a drug  may
be  extended for up to five years to compensate the patent holder
for  the  time required for FDA regulatory review of the product.
This law also establishes a period of time following FDA approval
of  certain drug applications during which the FDA may not accept
or approve applications for similar or identical drugs from other
sponsors. Any extension under the Patent Term Restoration Act and
any  extension  under  GATT  are  cumulative.  There  can  be  no
assurance that the Company will be able to take advantage of such
patent  term  extensions or marketing exclusivity  provisions  of
these laws. While the Company cannot predict the effect that such
changes  will have on its business, the adoption of such  changes
could have a material adverse effect on the Company's ability  to
protect  its  proprietary information and sustain the  commercial
viability  of  its  products.  Furthermore,  the  possibility  of
shorter terms of patent protection, combined with the lengthy FDA
review  process  and  possibility of  extensive  delays  in  such
process, could effectively further reduce the term during which a
marketed product could be protected by patents.

      The  Company  also relies on trade secrets and  proprietary
know-how.  The Company has been and will continue to be  required
to  disclose its trade secrets and proprietary know-how not  only
to  employees  and  consultants, but also to potential  corporate
partners, collaborators and contract manufacturers.  Although the
Company seeks to protect its trade secrets and proprietary  know-
how,  in  part  by entering into confidentiality agreements  with
such  persons  or organizations, there can be no  assurance  that
these  agreements  will not be breached, that the  Company  would
have adequate remedies for any breach or that the Company's trade
secrets  will  not  otherwise become known  or  be  independently
discovered by competitors.

Dependence on Others for Manufacture

      The  Company  currently  does not have  any  capability  to
manufacture  products under current good manufacturing  practices
("cGMP")  as required by the FDA.  It relies on third parties  to
manufacture  and formulate Glofil and Inulin and  to  manufacture
and  formulate  CPC-111  and CPC-211,  its  two  drug  candidates
currently in clinical trials. Although the Company believes  that
it  will  be able to contract with alternative suppliers for  its
products  if  its  current suppliers are  unable  to  supply  the
Company  with its needs for bulk and formulated drugs, there  can
be  no  assurance that this will be the case or that the need  to
contract  with additional suppliers will not delay the  Company's
ability  to  have  its products manufactured.  There  can  be  no
assurance that these manufacturers will meet either the Company's
requirements  for quality, quantity and timeliness or  the  FDA's
cGMP  requirements or that the Company would be able  to  find  a
substitute  manufacturer for any of its products in  the  future.
In  the  event  that the Company is unable to  obtain  or  retain
contract  manufacturers that can manufacture its  products  under
cGMP  requirements,  or to obtain manufacturing  on  commercially
acceptable  terms,  it  may  not be  able  to  commercialize  its
products as planned.

Potential Claims

      Certain members of the Company's Scientific Advisory  Board
("SAB")  and  certain  Scientific  Advisors  who  have  developed
technology  used  for  the Company's products  are  employees  of
universities,  research  hospitals or  other  institutions.   The
Company believes that such institutions have no claim to  any  of
the Company's inventions, technology or products.  While no claim
has  been  asserted  by any such institution,  there  can  be  no
assurance that such institutions will not assert claims to any or
all  of  such inventions, technology or products or that, if  any
such  institution does assert such rights, the Company, if it  so
desires,  will  be able to acquire the rights thereto  from  such
institution at a commercially practical cost or at all.

Government Regulation

      The  Company's development, manufacture and  sale  of  drug
products  are  subject  to extensive and rigorous  regulation  by
federal,  state, local and foreign governmental authorities.   In
particular,  products for human health are subject to substantial
preclinical  and clinical testing and other approval requirements
by  the  FDA and comparable foreign regulatory authorities.   The
process for obtaining the required regulatory approvals from  the
FDA and other regulatory authorities takes many years and is very
expensive.  There can be no assurance that any drug developed  by
the Company will prove to meet all of the applicable standards to
receive  marketing approval.  There can be no assurance that  any
such  approvals  will be granted on a timely basis,  if  at  all.
Delays  in and costs of obtaining these approvals could adversely
affect  the Company's ability to commercialize its drugs  and  to
generate significant sales revenues.  If regulatory approval of a
drug  is  obtained,  such approval may involve  restrictions  and
limitations on the use of the drug.

      Other  conditions for an approval are based on  the  drug's
manufacture and the quality control procedures in place, such  as
cGMP.  Failure to insure compliance with cGMP requirements  could
result  in  delay or termination of clinical trials or withdrawal
of an approval. Following market approval, the drug will continue
to be subject to compliance with applicable federal, state, local
and  foreign laws and regulations. There can be no assurance that
the  FDA will grant approval of any of the Company's drugs  in  a
timely manner or at all.

Governmental  Reforms

      Health  care  reform is an area of increasing national  and
international attention and a priority of many elected  officials
in  the  United States. Several proposals to modify  the  current
health  care  system in the United States to improve  access  and
control costs are currently being considered by federal and state
governments.  It is uncertain what legislation, if any,  will  be
adopted or what actions governmental or private payors for health
care  goods  and  services may take in response  to  proposed  or
actual  legislation  in the United States.   The  Company  cannot
predict the outcome of health care reform proposals or the effect
such reforms may have on its business.

Clinical Trial and Product Liability Claims and Uninsured Risks

      The Company may be exposed to liability resulting from  the
conduct of its clinical trials or the commercial use, if any,  of
its  drugs. Such liability might result from claims made directly
by   patients,  hospitals,  clinics  or  other  consumers  or  by
pharmaceutical companies or others manufacturing  such  drugs  on
behalf  of  the  Company.  The Company does  not  currently  have
clinical trial or product liability insurance, and there  can  be
no  assurance that the Company will be able to obtain  or  afford
such  insurance,  if  applied  for,  or  that  any  coverage,  if
obtained,  will  be  adequate  to  protect  the  Company  against
liability.

Competition and Technological Change

      The  products that the Company is marketing and  the  drugs
that  the Company is developing may compete for market share with
alternate  therapies.   A number of companies  are  pursuing  the
development  of  novel  pharmaceuticals  which  target  the  same
diseases  as the Company is targeting.  Many of these competitors
have  substantially  greater  capital  resources,  research   and
development  staffs and facilities than the  Company.   They  may
develop  and  introduce products and processes  competitive  with
those  of  the  Company.   They represent  significant  long-term
competition for the Company. For certain of the Company's  drugs,
an  important factor in competition may be the timing  of  market
introduction of these competitive products.  This timing will  be
based  on  the  effectiveness  with  which  the  Company  or  the
competition  can complete clinical trials and approval  processes
and  supply  quantities of these products to market.  Competition
among  products approved for sale will be based on,  among  other
things,   efficacy,   safety,   reliability,   price,   marketing
capability and patent position.

       The  pharmaceutical  industry  has  undergone  rapid   and
significant technological changes. The Company expects  that  the
technologies  associated with its research and  development  will
continue to develop rapidly.  There can be no assurance that  the
Company  will be able to establish itself in such fields  or,  if
established,  that  it  will be able to  maintain  a  competitive
position.    Further,  there  can  be  no  assurance   that   the
development  by others of new or improved processes  or  products
will  not make the Company's products and processes, if any, less
competitive or obsolete.

Dependence on Key Personnel; Conflicts of Interest

      The  Company is dependent upon the active participation  of
Paul J. Marangos, Ph.D., who serves as the Company's Chairman  of
the  Board, President and Chief Executive Officer.  The  loss  to
the Company of the services of Dr. Marangos could have a material
adverse  effect  upon  the  Company's  future  operations.    Dr.
Marangos  has  entered  into  an employment  agreement  with  the
Company  which  provides for his continued  employment  with  the
Company through August 1997.

      The  Company's success also depends in large  part  on  its
ability  to  attract  and retain other qualified  scientific  and
management  personnel.  The Company faces  competition  for  such
persons  from other companies, academic institutions,  government
entities and other organizations.  There can be no assurance that
the  Company  will  be  successful  in  recruiting  or  retaining
personnel  of  the  requisite caliber or in adequate  numbers  to
enable it to conduct its business as proposed.  Furthermore,  the
Company's expected expansion into activities requiring additional
expertise  in  manufacturing,  sales  and  marketing  will  place
increased  demands  on  the  Company's resources  and  management
skills.

Limited Sales and Marketing Capability

      The  commercialization of products such  as  the  Company's
drugs is an expensive and time-consuming enterprise.  The Company
now  has  has no experience in sales, marketing or distributiotwo
sales  representative for Glofil and Inulin and intends  to  hire
additional  sales  representatives as  sales  of  those  products
increase  and/or other products are acquired by the Company.   To
market  any of its drugs directly, the Company expects to develop
a   marketing  and  sales  force  with  technical  expertise  and
supporting distribution capability.  The Company believes that it
will be able to serve the hospital market in North America do  so
with  a  50  to 100 person sales and marketing staff.  since  its
drugs  will  be sold primarily to and administered in acute  care
facilities  rather than sold directly to physicians'  offices  or
retail  drug  stores. There can be no assurance that the  Company
will  be  able  to establish successfully sales and  distribution
capabilities  or be successful in gaining market  acceptance  for
its drugs or to obtain the assistance of any other pharmaceutical
company in these efforts if it should seek assistance.

Reimbursement

     In both domestic and foreign markets, sales of the Company's
products  will  be  dependent  in part  on  the  availability  of
reimbursement  from third party payors, such  as  government  and
private  insurance  plans.  Third party payors  are  increasingly
challenging the prices charged for medical products and services.
There  can  be no assurance that the Company's products  will  be
considered  cost-effective, that reimbursement will be  available
or,  if  available, that the payor's reimbursement policies  will
not  adversely affect the Company's ability to sell its  products
profitably.

Outstanding Warrants and Options

      There are currently outstanding 4,673,512 Class B Warrants.
Additional  shares of Common Stock are issuable as  follows:  (i)
1,183,312  shares  of  Common Stock  are  reserved  for  issuance
pursuant  to outstanding options under the Company's  1992  Stock
Option  Plan  and (ii) 138,500 shares are reserved  for  issuance
pursuant  to  outstanding options under the Company's  1993  Non-
Employee Directors' Stock Option Plan.   Holders of warrants  and
options are likely to exercise them when, in all likelihood,  the
Company  could obtain additional capital on terms more  favorable
than  those provided by the warrants and options.  Further, while
the  warrants  and  options are outstanding, they  may  adversely
affect  the  terms  on which the Company could obtain  additional
capital.

Potential Volatility of Stock Price

     There has been significant volatility in the market price of
securities of biomedical companies in general.  Announcements  of
technological  innovations  or new  commercial  products  by  the
Company  or  its competitors, developments concerning proprietary
rights,  clinical trial results, government policy or regulation,
relations  with  licensors or other corporate  partners,  general
market  conditions  or  public  concern  as  to  the  safety   of
biomedical products and period to period fluctuations in revenues
and  financial  results  may  have a significant  impact  on  the
Company's  business  and  on the market price  of  the  Company's
securities.

Dividends Not Likely

      The  Company has not paid any cash dividends on its  Common
Stock.   For  the  foreseeable  future  it  is  anticipated  that
earnings,  if  any,  which may be generated  from  the  Company's
operations will be used to finance the growth of the Company  and
that cash dividends will not be paid to holders of Common Stock.

                      PLAN OF DISTRIBUTION

     The  Company  has been advised that the Selling  Shareholder
may sell Shares from time to time, as market conditions permit on
the NASDAQ National Market System, or otherwise, through ordinary
brokerage  transactions,  in negotiated  transactions,  at  fixed
prices  which may be changed, at market prices prevailing at  the
time  of sale, at prices related to such prevailing market prices
or at negotiated prices.  The Selling Shareholder may effect such
transactions  by selling the Shares to or through broker-dealers,
and  all such broker-dealers may receive compensation in the form
of   discounts,  concessions  or  commiswions  from  the  Selling
Shareholder  and/or the purchasers of the Shares  for  whom  such
broker-dealers  may  act  as  agent  or  to  whom  they  sell  as
principal, or both (which compensation as to a particular broker-
dealer  might  be  in  excess  of  customary  commissions).   The
aforementioned methods of sale may not be all-inclusive.

     Any  broker-dealer  acquiring the Shares  in  the  over-the-
counter  market  from  the  holder may  sell  the  Shares  either
directly, in its normal market-making activities, through  or  to
other brokers on a principal or agency basis or to its customers.
Any such sales may be at prices then prevailing in the over-ther-
counter  market,  at  prices related to  such  prevailing  market
prices  or at negotiated prices to its customers or a combination
of  such  methods. The Selling Shareholder and any broker-dealers
that  act in connection with the sale of Shares hereunder may  be
deemed  to be "underwriters" within the meaning of Section  2(11)
of  the  Securities  Act; any commissions received  by  them  and
profits on any resale of the Shares as principal might be  deemed
to be underwriting discounts and commissions under the Securities
Act.  Any  such  commissions, as well as other  expenses  of  the
Selling Shareholder and applicable transfer taxes, are payable by
such parties, as the case may be.

     The  Company has agreed to indemnify the Selling Shareholder
against certain liabilities, including certain liabilities  under
the Securities Act.

Item 15.  Indemnification of Officers and Directors.

      Under Section 317 of the California Corporations Code,  the
Registrant  is  authorized to indemnify its directors,  officers,
employees and other agents against liabilities they may incur  in
such  capacities,  including  liabilities  under  the  Act.   The
Registrant's  Bylaws provide that the Registrant  will  indemnify
its  directors and executive officers and may indemnify its other
officers, employees and other agents to the full extent permitted
by  law.  The Bylaws further provide that rights, conferred under
such  Bylaws  shall not be deemed to be exclusive  of  any  other
rights  such  persons may have or acquire under any statute,  any
provisions of the Registrant's Restated Articles of Incorporation
or  Bylaws,  or  any  agreement,  vote  of  the  shareholders  or
disinterested directors or otherwise.

       In   addition,  the  Registrant's  Restated  Articles   of
Incorporation  provide that to the fullest  extent  permitted  by
California  law, the Company's directors will not  be  personally
liable   for  monetary  damages  for  breach  of  the  directors'
fiduciary duty of care to the Company and its shareholders.  This
provision  in  the  Restated Articles of Incorporation  does  not
eliminate  the  duty  of  care, and in appropriate  circumstances
equitable remedies such as an injunction or other forms  of  non-
monetary  relief  would  remain available under  California  law.
Each director will continue to be subject to liability for breach
of  the director's duty of loyalty to the Registrant, for acts or
omissions  not in good faith or involving intentional  misconduct
for  knowing  violations of law, for actions leading to  improper
personal  benefit,  for  acts  or omissions  that  constitute  an
unexcused pattern of inattention that amounts to an abdication of
the director's duty to the Registrant or its shareholders and for
payment   of   dividends,  approvals  of  stock  repurchases   or
redemptions  or  loans  or  guarantees that  are  unlawful  under
California  law.   This provisions does not affect  a  director's
responsibilities  under  any other  laws,  such  as  the  federal
securities laws or the state or federal environmental laws.

      There  is  no  pending  material litigation  or  proceeding
involving  a  director, officer, employee or other agent  of  the
Registrant  as to which indemnification is being sought,  nor  is
the  Registrant  aware  of  any pending  or  threatened  material
litigation that may result in claims for indemnification  by  any
director, officer, employee or other agent.

Item 17.  Undertakings.

     Insofar as indemnification for liabilities arising under the
Securities  Act of 1933 may be permitted to directors,  officers,
and  controlling  persons  of  the  Registrant  pursuant  to  the
provisions described in Item 15 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.

      The  undersigned Registrant hereby undertakes: (1) 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 of 1933;

(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   the   registration    statement.
Notwithstanding the foregoing, any increase or decrease in volume
of  securities  offered (if the total dollar value of  securities
offered  would  not  exceed that which was  registered)  and  any
deviaiton  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  prreviously   disclosed   in   the
registration statement or any material change to such information
in  the registration statement; rovided however, that clauses (i)
and  (ii) do not apply if the information required to be included
in  a  post-effective amendment by these clauses is contained  in
periodic  reports filed by the Registrant pursuant to section  13
or  section 15(d) of the Securities Exchange Act of 1934 that are
incorporated  by  reference  in the registration  statement;  (2)
that,  for  the  purpose of determining any liability  under  the
Securities Act, each post-effective amendment 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; and
(3)  to  remove  from registration by means of  a  post-effective
amendment  any  of the securities being registered  which  remain
unsold at the termination of the offering.

      The  undersigned  Registrant  hereby  undertakes:  (1)  for
purpose of determining any liability under the Securities Act  of
1933,  the information omitted from the form of prospectus  filed
as  part of the registration statement in reliance upon Rule 430A
and  contained in the form of prospectus filed by the  Registrant
pursuant  to Rule 424(b)(1) or (4) or 497(h) under the Securities
Act  shall be deemed to be part of the registration statement  as
of  the  time it was declared effective; (2) for the  purpose  of
determining any liability under the Securities Act of 1933,  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; and (3) for purposes of determining any liability  under
the  Securities  Act  of 1933, each filing  of  the  Registrant's
annual  report pursuant to Section 13(a) or Section 15(d) of  the
Securities  Exchange  Act of 1934  (and, where  applicable,  each
filing  of  an employee benefit plan's annual report pursuant  to
Section  15(d)  of the Securities Exchange Act of 1934)  that  is
incorporated by reference in the registration statement 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.
                                
                           SIGNATURES

Pursuant  to the requirements of the Securities Act of 1933,  the
Registrant  has  duly caused this Registration  Statement  to  be
