PROSPECTUS
(Subject to completion, dated April 29, 1999)



                                2,554,825 Shares
                                ALYN CORPORATION
                                  Common Stock


         This  prospectus  relates  to the public  offering,  which is not being
underwritten,  of 2,554,825  shares of the common stock of Alyn  Corporation  by
certain  stockholders  of Alyn.  Certain  stockholders  of Alyn  Corporation are
offering for resale and selling under this prospectus up to 2,554,825  shares of
Alyn common  stock to be issued upon  conversion  of our 6% Senior  Exchangeable
Promissory Note due March 10, 2002 and our Series B Exchangeable Preferred Stock
and upon exercise of warrants to purchase our common stock.

         The prices at which such selling  stockholders may sell the shares will
be  determined  by the  prevailing  market price for the shares or in negotiated
transactions.  We will  not  receive  any of the  proceeds  from the sale of the
shares.

         Our common  stock is quoted on the  Nasdaq  National  Market  under the
symbol  "ALYN." On April 26, 1999,  the last  reported sale price for the common
stock was $3.125 per share.




                                   ----------


         You should carefully  consider the risk factors  beginning on page 1 of
this Prospectus  before  purchasing any of our common stock being offered by the
selling stockholders.

         Neither the Securities and Exchange Commission nor any state securities
commission has approved or disapproved of these securities or determined if this
prospectus  is truthful or  complete.  Any  representation  to the contrary is a
criminal offense.

                                  RISK FACTORS

         An investment in our common stock  involves a high degree of risk.  You
should  carefully  consider the risks  described below when making an investment
decision.  The risks  and  uncertainties  described  below are not the only ones
facing our company.  If any of the following risks actually occur, our business,
financial  condition or results of operations would likely suffer. In such case,
the trading  price of our common  stock could  decline,  and you may lose all or
part of your investment.

We have a limited operating history, limited revenues and prior losses

         We commenced our materials development  activities in 1990. However, we
only  completed our  manufacturing  facilities in 1998 and therefore have a very
limited  operating  history.  Our  limited  operating  history  has  resulted in
extremely  limited revenues through 1998, with total revenues of $1.3 million in
1998,  $364,000 in 1997 and $194,000 in 1996. Due to these limited  revenues and
our extensive materials and facilities development activities, we had net losses
of $12.1 million, $7.3 million and $2.3 million for the years ended December 31,
1998,  1997 and 1996,  respectively.  We are also  expecting  to incur losses in
fiscal  year 1999 and may  continue  to incur  losses  thereafter.  We may never
generate  sufficient  revenues to achieve  profitability.  Even if we do achieve
profitability,  we may not sustain or increase  profitability  on a quarterly or
annual basis in the future.


Our future operating results will fluctuate significantly

         We have experienced, and will likely continue to experience, long sales
cycle times,  lengthy customer design  processes for new product  introductions,
and market trends that may significantly limit management's  ability to forecast
accurately  time-to-market  schedules or short-term  results of  operations.  We
cannot predict our operating results due to the uncertainty of these factors and
our limited operating history. Our operating results may vary significantly from
quarter to quarter,  in part because of the costs associated with changes in our
products and personnel and the size and actual  delivery dates of orders for our
products.  As a result,  our operating results for any particular quarter should
not  be  considered  indicative  of  any  future  results  and  period-to-period
comparisons  of our  operating  results  will  not  necessarily  be  meaningful.
Fluctuations  caused by variations in quarterly operating results or our failure
to meet market  analysts'  projections  or public  expectations  could cause the
market price of our common stock to decline and perhaps decline significantly.


We must  achieve  significant  product  sales to  offset  substantial  lease and
capital commitments we made to establish production capability

         We have entered into long-term leases for our two facilities located in
Irvine,  California.  For our main  facility,  we have entered into a lease that
expires in 2008 with a five-year  option. We also have a ten-year lease expiring
in 2008 for our second Irvine facility. We have committed substantial capital to
provide both facilities with significant production capability. Unless and until
we achieve a significant level of sales of our Boralyn- based products,  we will
have substantial  production  over-capacity and under-absorbed  costs that would
cause us to incur substantial operating losses.


We have limited manufacturing history and significant manufacturing risks

          Our limited  operating  history has resulted in limited  experience in
manufacturing  our  products  in  commercial  quantities.  While  we  have  made
substantial   lease  and  capital   commitments  to  support  our  manufacturing
capabilities,  we cannot be sure that we will fully utilize our capacity or that
our facilities will be adequate for all of our future fabrication  requirements.
In addition, the manufacture of our products presents several potential hazards.
For example,  the  manufacturing  processes for Boralyn utilize high temperature
and  high  pressure  and may be  subject  to  volatile  chemical  reactions.  In
addition,   a  mechanical  or  human  failure  or  natural   disasters  such  as
earthquakes, characteristic of Southern California, could result in interruption
of our  manufacturing  activities  or  significantly  impact  our  manufacturing
capacity.  Moreover,  our  manufacturing  operations will use certain  equipment
that, if damaged,  inoperable or  unavailable,  could disrupt our  manufacturing
operations.  To address  these risks,  we have  obtained  business  interruption
insurance with coverage for lost profits and out-of-pocket  expenses of up to $8
million per  occurrence.  In addition,  we maintain  other property and casualty
coverage.  Despite our efforts to minimize and insure against our  manufacturing
risks, any extended  interruption of our  manufacturing  operations would have a
material  adverse  effect  on our  business,  operating  results  and  financial
condition.


Our products have not yet gained market acceptance in commercial quantities

          Market  acceptance  of our products in commercial  quantities  depends
upon pricing of products and our ability to manufacture and deliver  products on
a timely basis. In addition, our ability to achieve commercial acceptance of our
products is dependent upon our ability to demonstrate  the advantages of Boralyn
products  over  competing  material  methodologies  and  products.  We also have
experienced,  and will likely  continue  to  experience,  long sales  cycles and
lengthy  customer  product  design  times prior to  production  orders.  We must
address  each  of  these  factors  effectively  in  order  to  achieve  customer
acceptance  in  commercial  quantities of Boralyn or our other current or future
products.  The costs of our marketing  efforts will be  substantial  and will be
recorded as expenses as they are incurred, notwithstanding that the benefits, if
any,  from  those  marketing  efforts  (in  the  form  of  revenues)  may not be
reflected, if at all, until subsequent periods.


We may be unable to obtain the additional capital required to grow our business

          Our ability to grow our business is highly  dependent upon our ability
to  generate  capital  from our  operations  and to raise  needed debt or equity
financing.  If we are able to achieve our  operating  plan for 1999,  we believe
that our cash on hand  (including debt and equity  investment  capital raised in
the first quarter of 1999), capital generated from our internal operations,  and
planned  equipment  and  accounts   receivable   financing  should  satisfy  our
anticipated  capital needs for the next 12 months.  However, if we fail to reach
our planned revenue objectives, we may have inadequate working capital. Also, if
we fail to complete our planned equipment and accounts receivable financing,  we
may have  inadequate  capital to finance our  operations.  Our ability to obtain
future  working  capital debt financing will be dependent in part on the quality
and amount of our trade receivables,  inventory and unsecured capital equipment.
If we are  unable  to  receive  adequate  debt  financing,  we may  have to seek
additional equity financing which may not be available on favorable terms, if at
all. Our ability to achieve future  liquidity and capital  funding  requirements
through our operations will depend on numerous factors, including:

         o results of  marketing  our metal  matrix  composite  capabilities;  o
         market  acceptance of our products;  o the timing of production  orders
         and our ability to make delivery of products;  o our costs of sales and
         timing of growth in sales; and o our ability to effectively  manage our
         marketing and manufacturing activities.


We depend on our key personnel and management team

         Our future success and  profitability is  substantially  dependent upon
the  performance  of our  executives,  Arne Van Roon  (our  President  and Chief
Executive Officer), Robin A. Carden (our Founder),  Richard L. Little (our Chief
Financial  Officer  and  Secretary)  and Jon A.  Knartzer  (our Vice  President,
Operations).  We seek to retain our key personnel with competitive  compensation
and each of our senior executives has a substantial potential equity interest in
the form of stock options.  However,  a departure by any of these individuals or
any other key employees  could  significantly  diminish our level of management,
technical, marketing and sales expertise and we would have the difficult task of
finding and hiring  replacements who have these skills. We do maintain a key-man
life insurance policy of $2.5 million on the life of Mr. Carden;  however, we do
not maintain key-man life insurance  policies on either Messrs. Van Roon, Little
or Knartzer.

         Our future  growth  will be  dependent  upon our ability to attract and
retain additional qualified management,  technical,  scientific,  administrative
and other personnel. Due to our location in Irvine, California and the nature of
our  business,  we  believe  we  will  experience  significant  competition  for
qualified management, supervisory, engineering and other personnel.


We face rapid technological change in our industry which may necessitate 
development of new products

         We operate in a rapidly  evolving field - advanced  materials - that is
likely to be  affected  by future  technological  developments.  Our  ability to
anticipate changes in technologies,  markets and industry trends, and to develop
and  introduce  new and  enhanced  products  on a timely  basis will be critical
factors in our ability to grow and remain competitive. We cannot be sure that we
will be able to develop new  products or that any new  products  can be marketed
successfully.  In addition,  development  schedules for new or improved products
are  inherently  difficult  to predict  and are subject to change as a result of
shifting priorities in response to customers'  requirements and competitors' new
product  introductions.  If we fail to timely develop and introduce new products
or to  enhance  our  current  products,  our  business,  operating  results  and
financial condition could be materially adversely affected.  Moreover, we expect
to  devote  substantial   resources  to  technology   development  efforts.  For
accounting purposes,  the costs of those efforts will be recorded as expenses as
they  are  incurred,  notwithstanding  that  the  benefits,  if  any,  from  our
technology  development  efforts (in the form of increased revenues or decreased
product costs) may not be reflected,  if at all, until subsequent  periods. As a
result, our  period-to-period  operating results could be adversely impacted and
difficult to predict.


  We currently depend on a limited number of customers

         Due to the early stage nature of our business, we currently have only a
limited  number of  customers,  several of whom may be material to our near-term
results of operations.  Even after we mature, however,  certain customers may be
material to our business,  operations  and future  prospects.  We cannot be sure
that one or more  principal  customers  will not suffer  business  or  financial
setbacks  resulting in reduction or  cancellation of product orders or our being
unable to obtain  payment from such  customers at any time or from time to time.
The  loss of sales  to one or more  significant  customers,  or our  failure  to
successfully market our products to new customers, could have a material adverse
effect on our business, operating results and financial condition.


 We currently depend on a limited number of suppliers

         We  presently  purchase  our  principal  ceramic  raw  material,  boron
carbide,  from a limited  number  of  suppliers,  including  one  supplier  that
provides  approximately 50% of our present  requirements.  Our business would be
materially and adversely affected if we are unable to continue to purchase boron
carbide at prices and on terms comparable to those presently  available from our
principal  suppliers.  Although we believe that boron carbide is available  from
other  suppliers,  we  project  that to take  full  advantage  of the  potential
opportunity,  we must develop additional boron carbide supplies. There can be no
assurance that we will be able to continue to obtain desired quantities of boron
carbide on a timely basis or at prices and terms we consider reasonable.


We depend on the protection of our patents

         We have been granted one United States patent that contains claims that
cover the use of Boralyn.  We believe this patent  provides  protection  for our
proprietary  Boralyn  technology.  We  have  been  granted  additional  patents,
including divisional (extension) patents and  continuation-in-part  patents that
stem from our original patent  application.  We have also applied for additional
patents.  We cannot be sure that our existing patents, or any other patents that
may be  granted,  will be valid and  enforceable  or provide us with  meaningful
protection from competitors.  Further, we cannot be sure that any pending patent
application  will issue or that any claim under pending  patents will provide us
protection  against  infringement.  If our present or future  patent  rights are
ineffective  in protecting us against  infringement,  our marketing  efforts and
future  revenues  could be materially  and adversely  affected.  Moreover,  if a
competitor  were to infringe  any of our  patents,  the costs of  enforcing  our
patent rights may be substantial or even prohibitive. We cannot be sure that our
future  products  will not infringe the patent  rights of others or that we will
not be forced to expend substantial funds to defend against  infringement claims
of, or to obtain  licenses from,  third parties.  We currently have only limited
patent  protection for our technology  outside the United States,  and we may be
unable to obtain even  limited  protection  for our  proprietary  technology  in
certain foreign countries.


We depend on our trademarks for current and future markets

         The market for our  products is and will remain  dependent in part upon
the goodwill engendered by our trademarks and trade names.  Trademark protection
is  therefore  material  to  our  business.  Although  Boralyn  is a  registered
trademark in the United  States,  we cannot be certain that we can  successfully
assert trademark or trade name protection for our significant marks and names in
the  United  States or other  markets,  and the costs of such  efforts  could be
substantial.


Our industry is very competitive

         The materials industry is highly competitive.  We compete in our chosen
markets  against several larger domestic and  multi-national  companies,  all of
which are well  established in their respective  markets and have  substantially
greater financial and other resources than us. There are also several competing,
small  advanced  materials  companies,   similar  to  Alyn.  Competitive  market
conditions  could  adversely  affect our  results of  operations  and  financial
condition if we were required to reduce  product  prices to remain  competitive,
were  unable  to  achieve  significant  sales  of  our  products  or  unable  to
successfully develop and sell new or enhanced products.


We face product liability risks

         As a  participant  in the  materials  industry,  we  face  an  inherent
business risk of exposure to product  liability  claims in the event that any of
our products are alleged to be defective or cause harmful  effects.  The cost of
defending or settling product liability claims may be substantial.  We currently
maintain,  and intend to  continue  to  maintain,  product  liability  insurance
coverage.  However,  we  cannot  be sure  that we  will be able to  obtain  such
insurance  on  acceptable  terms  in the  future  or that  such  insurance  will
adequately cover any claims.


Our  stock  price  could be  adversely  affected  by the sale of shares
issuable to holders of our recently issued preferred stock and Exchangeable Note

         During  the first  quarter  of 1999,  we raised  an  aggregate  of $6.0
million ($5.65  million,  net of expenses) in financing  through the issuance of
Series  A  Preferred  Stock,  Exchangeable  Preferred  Stock  and  a  6%  Senior
Exchangeable  Promissory  Note  ("Exchangeable  Note") due March 10,  2002.  The
Series A Preferred Stock is  exchangeable  for common stock beginning in January
2000, while the Series B Exchangeable  Preferred Stock and the Exchangeable Note
are  currently  exchangeable  for common stock at set prices of $3.57 and $3.645
("Set Prices"),  respectively.  Each of the holders of these securities received
registration  rights for the common stock underlying their securities and we are
required  to  file  a  registration  statement  for  the  holders  of  Series  B
Exchangeable   Preferred  Stock   ("Exchangeable   Preferred   Stock")  and  the
Exchangeable  Note in  April  1999.  Additionally,  each of  these  exchangeable
securities  has an exchange rate that is based on the lesser of the Set Price or
the market price at the time the  securities  are  exchanged.  The  Exchangeable
Preferred Stock and the Exchangeable Note are each exchangeable at up to as much
as a 15%  discount  to the  market  price  if the  market  price at the time the
securities are exchanged is less than the Set Price. At a minimum, the number of
shares of common stock  issuable  upon  exchange of all of these  securities  is
1,617,086.  In addition,  we will be required to issue 200,000  shares,  up to a
maximum of 320,000  shares,  of common  stock  pursuant to  warrants  granted in
connection with these  financings.  Any decrease in the price of our stock could
result in the issuance of a substantial number of additional common stock shares
that would be  immediately  available  for  resale on the public  market for the
Exchangeable  Preferred  Stock and the  Exchangeable  Note.  Depending  upon the
trading  volume  of our  stock,  any  significant  block  sales of these  shares
issuable in exchange  for these newly  issued  securities  could have an adverse
effect on the market price of our stock.  Additionally,  any  perception  by the
public that these shares might be resold  immediately  and are not to be held as
long term investments could materially and adversely affect our stock price. Any
adverse  impact  on  our  stock  price  resulting  from  these  recently  issued
exchangeable  securities would cause these securities to become exchangeable for
even more shares of common stock.  Also, any negative  impact to our stock price
caused by these  exchangeable  securities  could  impair  our  ability  to raise
additional equity capital.


We may be required to issue significant numbers of common stock upon a market
price decline

         We do not know the exact  number of shares of our common  stock that we
will issue upon conversion of our newly issued  exchangeable  securities because
they  potentially  have floating  conversion  prices based on the average market
prices of the common  stock for a number of trading  days  immediately  prior to
conversion.  The floating  conversion price feature of the Exchangeable Note due
March 10,  2002 and the  Exchangeable  Preferred  Stock  begin in  August  1999.
Generally, decreases in the market price of the common stock below their initial
conversion  prices would result in more shares of common stock being issued upon
their  conversion.  See  "Description  of  Certain  Provisions  of Our 6% Senior
Exchangeable  Promissory  Note Due March 10, 2002" and  "Description  of Certain
Provisions of Our Series B Exchangeable Preferred Stock".


The ownership limitations of our preferred stock and Exchangeable Note may not
protect against dilution

         We may not issue shares of our common stock to holders of our preferred
stock if such  issuance  would result in such holders  beneficially  owning more
than 9.9% of our outstanding  common stock.  The 9.9% ownership  limitation does
not prevent the holders from  converting into common stock and then selling such
common stock to stay below the  limitation,  and the limitation may be waived by
each holder of the Exchangeable Preferred Stock with 75 days prior notice to us.

         Also,  under  the  rules  of the  National  Association  of  Securities
Dealers,  Inc., the holders of our Series A Preferred  Stock,  our  Exchangeable
Preferred Stock and our Exchangeable  Note may not exchange their securities for
common stock if such  exchange  would lead to the issuance of more than 19.9% of
our  outstanding   common  stock  as  of  the  respective  issue  dates  of  the
exchangeable securities. However, the 19.9% limitation will cease to exist if we
receive  stockholder  approval for issuances in excess of 19.9%.  We are seeking
such  stockholder  approval in accordance with NASD Rule 4460 at our 1999 Annual
Meeting.


We may be required to make cash payments to holders of our preferred stock and
Exchangeable Note

         We may be  required to make cash  payments to holders of our  preferred
stock and  Exchangeable  Note if we do not  timely  deliver  common  stock  upon
exchange  of the  securities  or if we  fail to  keep a  registration  statement
effective for the  underlying  shares of common stock.  Such cash payments would
adversely  affect our financial  condition and ability to implement our business
plans. In addition, if we do not obtain stockholder approval to remove the 19.9%
limit,  we would be required  to make cash  payments in the event the holders of
the exchangeable  securities attempted to convert over the 19.9% limit. The cash
payments  would be equal to the  number of shares of common  stock that we could
not issue because of the 19.9% limit  multiplied by the market price at the time
of the  attempted  conversion.  In such an event,  we will be  required to raise
funds  elsewhere,  which could be  difficult.  If we do not receive  stockholder
approval as we are required,  there can be no assurance that we would be able to
obtain adequate sources of additional capital.

Our stock price could be  adversely  affected  by the  perception  that
certain  stockholders  could  require  us to sell  their  shares of our stock by
exercising their registration rights

         Future  sales of our common stock by existing  stockholders  under Rule
144 could have an adverse effect on the price of our stock. In addition, certain
of our stockholders of common stock have  contractual  registration  rights.  No
prediction  can be made as to the effect that future sales of common  stock,  or
the  availability  of shares of common stock for future sales,  will have on the
market price of our stock  prevailing  from time to time.  Sales of  substantial
amounts of common stock,  or the perception  that such sales could occur,  could
adversely affect prevailing market prices for our stock.


         We are subject to risks associated with year 2000 compliance

         We are in the process of  upgrading  or replacing  our  accounting  and
management  information systems to be Year 2000 compliant and believe we will be
Year 2000  compliant on a timely  basis.  We will use both internal and external
resources to reprogram  and/or  replace any  deficiencies.  We are not currently
aware of any other  incompatibility  and believe  that no material  expenditures
will be  required.  We do not  believe  that the Year 2000  issue  will have any
material  effect on our operations and we have  determined  there is no exposure
related to our products.  Formal  communications  have been  initiated  with all
significant  suppliers  and large  customers to determine the extent to which we
are  vulnerable to such parties'  failure to address their own Year 2000 issues.
We expect  to have  analyzed  and  accessed  the  possible  risk of  significant
business  interruptions  as a result of any such party's  noncompliance  by June
1999. At that time, any necessary contingency plans will be developed to address
any  material  consequences  that we could suffer if such party is not Year 2000
compliant. Despite our efforts to assess Year 2000 compliance, we cannot be sure
that the failure of other  companies to  adequately  address the Year 2000 issue
will not have a material  adverse effect on our business,  operating  results or
financial  condition.  Overall,  we expect to complete our Year 2000  compliance
efforts in 1999.  The total  estimated  project  cost,  which is not  considered
material,  includes the estimated  costs and time  associated with the impact of
third party compliance.  However, there can be no guarantee that these estimates
will be achieved and actual results could differ materially from those plans.


Certain of our stockholders retain substantial influence

         Certain  of our  present  holders  of common  stock  own a  substantial
majority  of  the  outstanding  shares  of  common  stock.  Consequently,  those
stockholders  have the ability to elect all of our  directors and to control the
outcome of all other issues submitted to our stockholders.  Additionally,  those
stockholders  would be able to influence  significantly a proposed  amendment to
our  charter,  a merger  proposal,  a  proposed  sale of assets  or other  major
corporate  transaction or a non-negotiated  takeover attempt. Such concentration
of ownership may discourage a potential acquirer from making an offer to buy our
company,  which, in turn,  could adversely affect the market price of our common
stock.

         In  addition,  under the terms of our  recently  completed  financings,
certain holders of the newly issued exchangeable securities must approve certain
actions,  including future  financings or issuance of senior  securities.  These
restrictions  could  affect  our  ability  to raise  capital  or effect  certain
corporate  changes  which  could  adversely  affect  our  business,  results  of
operations and financial condition.



<PAGE>



         Certain  provisions  of our  Exchangeable  Note could  discourage  some
potential  purchasers by making an  acquisition  of our Company or an asset sale
more difficult and expensive, including:

         o        adjustments  to the exchange  price of the  Exchangeable  Note
                  upon merger or consolidation  events,  reflecting  adjustments
                  made to the underlying common stock;
         o        requirement that upon a change of control, we make an offer to
                  buy  the  Exchangeable  Note  at the  greater  of  150% of the
                  principal  plus accrued and unpaid  interest and  penalties or
                  the   product  of  the  number  of  shares   into  which  such
                  Exchangeable Note can be exchanged and the market price on the
                  applicable date; and
         o        prohibition   against   selling   or   transferring   all   or
                  substantially all of our assets to any subsidiary or affiliate
                  except for cash or cash equivalent consideration.

         We have also  agreed to grant the  holders of the  Exchangeable  Note a
right of first  offer  with  respect  to  certain  issuances  of  equity or debt
securities,  and we are prohibited from obtaining additional senior indebtedness
for borrowed money without  written  consent of the holders of the  Exchangeable
Note  unless such  indebtedness  is not on par with or senior or superior to the
Exchangeable  Note or that such  borrowed  money is for  equipment  financing or
customary working capital lines of credit.

         Moreover,  the terms of our  Exchangeable  Preferred Stock prohibit any
merger or consolidation  unless the resulting entity assumes  obligations to the
holders of the Exchangeable Preferred Stock.


Certain of our charter  provisions could adversely affect the rights of
common stock and we are subject to Delaware anti-takeover provisions

         Under our charter,  the Board of Directors  has the  authority to issue
shares of preferred  stock and to determine the price,  rights,  preferences and
privileges  of those  shares  without  any  further  vote of, or action  by, our
stockholders.  The rights of holders of common stock will be subject to, and may
be adversely  affected by, the rights of holders of any preferred stock that has
been issued or may be issued in the future.  Issuance of preferred stock,  while
potentially   providing  desirable   flexibility  in  connection  with  possible
acquisitions  and other  corporate  purposes,  could have an effect of making it
more difficult for a third party to acquire a majority of our outstanding voting
stock.  Certain  provisions of Delaware law applicable to us may also discourage
third-party attempts to acquire control.


Our stock price may be volatile

         Trading volume and prices for our common stock could be subject to wide
fluctuations in response to quarterly  variations in our operations and results,
announcements  with  respect  to sales and  earnings,  as well as  technological
innovations,  and new product  developments  and other events or factors,  which
cannot be  foreseen  or  predicted  by us.  These  factors  include  the sale or
attempted  sale of a large  amount  of  securities  in the  public  market,  the
registration  for  resale of any shares of common  stock,  and the effect on our
earnings on existing or future  equity-based  compensation awards to management.
The market price of our common stock could also be influenced by developments or
matters not related to us such as the general volatility of the stock market.

                                 USE OF PROCEEDS

         We will not  receive  any  proceeds  from the sale of the shares of our
common stock being offered by the selling stockholders under this prospectus.



                              SELLING STOCKHOLDERS

         The selling stockholders acquired or will acquire the shares offered by
this prospectus upon their exchange of our 6% senior  Exchangeable  Note and our
Exchangeable  Preferred Stock, both of which were issued in March 1999, and upon
their   exercise  of  warrants  that  were  issued  in  connection   with  those
transactions.  In connection with those transactions, we have agreed to effect a
shelf registration,  of which this prospectus is a part, of the shares issued or
to be issued under the  Exchangeable  Note, the preferred stock and the warrants
in order to permit the selling  stockholders  to sell these  shares from time to
time  in the  public  market  or in  privately-negotiated  transactions.  We are
initially  registering  2,554,825  shares  of our  common  stock  that we may be
required to issue to the selling  stockholders upon exchange of the Exchangeable
Note or the preferred stock or upon exercise of the warrants. We may be required
to register additional shares of our common stock if:

     o    the market price of our common stock falls and results in additional 
          shares being issuable upon exchange of our Exchangeable  Note and our
          Exchangeable Preferred Stock ; or

     o    certain  dilutive events occur with respect to the common stock  
          underlying our Exchangeable Note, our Exchangeable Preferred Stock 
          and warrants.

         We cannot  determine  the actual  number of shares of our common  stock
that we will issue because the conversion prices of our exchangeable  securities
will  fluctuate  with the market price of our common  stock  beginning in August
1999. The number of shares  underlying our Exchangeable  Note due March 10, 2002
and our  Exchangeable  Preferred  Stock would increase if the  conversion  price
decreased.  See "Risk Factors -- Our stock price could be adversely  affected by
the sale of shares  issuable to holders of our recently  issued  preferred stock
and  Exchangeable  Note,"  "Description  of Certain  Provisions of Our 6% Senior
Exchangeable  Promissory  Note Due  March  10,  2002 --  Conversion  Price"  and
"Description of Certain Provisions of Our Series B Exchangeable  Preferred Stock
- -- Conversion Price."

         The following  table sets forth for each selling  stockholder,  and for
all selling  stockholders  in the aggregate,  the number of shares of our common
stock  underlying our Exchangeable  Note, our  Exchangeable  Preferred Stock and
warrants to purchase our common stock,  the number of shares of our common stock
that may be offered under this prospectus,  and the total shares of common stock
beneficially  owned by such  selling  stockholders.  The shares of common  stock
underlying our Exchangeable Note and our Exchangeable  Preferred Stock presented
on the table assume that the  exchange  for common  stock  occurred on April 26,
1999, at which time the set exchange  prices of $3.645 and $3.57,  respectively,
would have been  applicable.  The shares of common  stock being  offered  assume
that:  (i) the market price for the  Company's  common stock is equal to $3.125,
the same as the closing  price on April 26,  1999;  (ii) the exchange for common
stock occurs after December 6, 1999 for the  Exchangeable  Note and after August
19, 1999 for the Exchangeable  Preferred Stock,  such that the exchange price is
at a 15% discount to the market price; and (iii) include reserves for additional
shares of 25% for the Exchangeable  Note and 67% for the Exchangeable  Preferred
Stock, in accordance with the related agreements.

         Generally,  the rules of the Securities and Exchange  Commission define
beneficial  ownership to include  securities  with respect to which the investor
has voting or investment power. The rules also provide that beneficial ownership
includes  shares of common stock  underlying  options,  warrants and convertible
securities  that can be exercised or converted  within 60 days.  To that extent,
the number of shares of our Common Stock underlying our  Exchangeable  Note, our
Exchangeable  Preferred  Stock and the  warrants  presented on the table may not
present  the  actual  beneficial  ownership  from  time to  time of the  selling
stockholders  in  accordance  with  these  rules  because  of the  floating-rate
conversion  features of our Exchangeable Note and Exchangeable  Preferred Stock.
In that regard,  please see "Description of Certain  Provisions of Our 6% Senior
Exchangeable Note Due March 10, 2002" and "Description of Certain  Provisions of
Our  Exchangeable  Preferred  Stock" for a more  detailed  description  of these
factors.

         We are not able to  estimate  the amount of shares that will be held by
the selling  stockholders  after completion of this offering because the selling
stockholders may offer all or some of the shares and because there currently are
no agreements, arrangements or understandings with respect to the sale of any of
the shares.  The following table assumes that all of the shares being registered
will be sold. The selling  stockholders are not making any  representation  that
any shares covered by the  prospectus  will or will not be offered for sale. The
selling stockholders reserve the right to accept or reject, in whole or in part,
any  proposed  sale of shares.  The shares  offered  by this  prospectus  may be
offered from time to time by the selling stockholders named below.

 * Represents  beneficial ownership of less than 1% of the outstanding shares of
common stock. ** Prior to the offering,  the above listed  stockholders  did not
own any of the Company's common stock.

(1)  The  shares  of  common  stock  underlying  our  Exchangeable  Note and our
     Exchangeable  Preferred  Stock  presented  on the  table  assume  that  the
     exchange for common stock occurred on April 26, 1999, at which time the set
     exchange  prices  of  $3.645  and  $3.57,  respectively,  would  have  been
     applicable.

(2)  The shares of common stock being offered  assume that: (i) the market price
     for the Company's common stock is equal to $3.125,  the same as the closing
     price on April 26,  1999;  (ii) the  exchange for common stock occurs after
     December 6, 1999 for the  Exchangeable  Note and after  August 19, 1999 for
     the Exchangeable  Preferred Stock, such that the exchange price is at a 15%
     discount to the market  price;  and (iii) include  reserves for  additional
     shares  of 25%  for the  Exchangeable  Note  and  67% for the  Exchangeable
     Preferred Stock, in accordance with the related agreements.

(3)  This  registration  statement  also shall  cover any  additional  shares of
     common  stock which  become  issuable in  connection  with the shares being
     registered by reason of any stock dividend,  stock split,  recapitalization

Description of Certain Provisions of Our 6% Senior Exchangeable Promissory Note
Due March 10, 2002

         On March  10,  1999,  the  Company  issued  the  Exchangeable  Note and
warrants  to purchase  135,000  shares of common  stock at an exercise  price of
$3.0375 per share (the "Note  Warrants").  The gross  proceeds to the Company in
the  transaction  were  $3.0  million.  Certain  provisions  and  rights  of the
Exchangeable Note are summarized as follows:

         Interest  Rate.  Interest on the  outstanding  principal  amount of the
Exchangeable Note is payable at the rate of 6% per annum, payable  semiannually.
Such  interest  may be paid,  at the  option of the  noteholder,  either in cash
within 5 days of September 15 and March 15 of each year or by issuing additional
promissory notes. Upon an event of default, the interest on unpaid principal and
accrued and unpaid  interest will accrue at 6% plus an additional  14% per annum
until the default is cured by the Company or waived by the noteholder. Events of
default  include:  (i) a failure to pay principal,  interest,  or other required
payments  which is not  cured  within  10  calendar  days  after  notice of such
failure;  (ii) a  failure  to  perform  or comply  with  material  covenants  or
agreements which is not cured within 10 calendar days after notice; or (iii) the
delisting or  ineligibility  of the Company's common stock for trading on Nasdaq
for 10 trading days.

         Exchange Price.  The outstanding  principal  amount of the Exchangeable
Note is $3.0  million  and any  portion of that  amount is  exchangeable  at the
election of the  noteholder  into shares of common  stock.  The actual number of
shares of common stock issuable upon exchange of the  Exchangeable  Note will be
determined by the following formula:

                 (the principal amount of the Exchangeable Note
                   tendered for exchange plus any accrued but
                    unpaid interest being exchanged plus any
                    unpaid liquidated damages and penalties)

                                   divided by

            (the applicable exchange price at the time of exchange).

         The exchange  price is subject to  adjustment.  On or before  August 7,
1999, the exchange price of the Exchangeable  Note is equal to $3.645 per share.
Thereafter,  the exchange price of the  Exchangeable  Note is equal to either of
the following at the sole option of the noteholder: (i) $3.645 per share or (ii)
the average of any 3 closing bid prices as reported  by  Bloomberg  L.P.  for 22
trading days immediately preceding the applicable exchange date discounted by up
to 15% (8% discount through  September 6, 1999; 12% discount through December 5,
1999; and 15% after December 5, 1999).

         The  following  table sets  forth the number of shares of common  stock
issuable upon exchange of the Exchangeable  Note. It assumes the market price of
the common stock is 25%, 50%, 75%,  100%,  125% and 150% of the closing price of
the common  stock on April 26,  1999,  which was $ 3.125 per  share.  It further
assumes that the exchange occurs after December 5, 1999 at the required exchange
price of 85% of the closing price, except where the closing price is at or above
$3.645, in which case the exchange price is $3.645.

                           Percent of                Number of Shares
                          Market Price            Issuable Upon Exchange

                               25%                      4,517,647
                               50%                      2,258,824
                               75%                      1,505,882
                              100%                      1,129,412
                              125%                        823,045
                              150%                        823,045



<PAGE>




         In addition,  the exchange price of the Exchangeable Note is subject to
adjustment  upon the  occurrence  of certain other  events,  including,  but not
limited to: (i) capital  reorganizations of the Company; (ii)  reclassification,
exchange,  or substitution of the common stock;  (iii) declaration or payment of
dividends  or  distributions  on the  common  stock;  and  (iv)  subdivision  or
combination of the common stock.

         Anti-dilution  Protection.  Until March 15, 2002,  if the Company sells
common  stock at a price  lower  than any  applicable  exchange  price for the 6
months immediately preceding such issuance or sale, then the Company is required
to issue to the  noteholder a number of shares of common stock as  determined by
(i)  subtracting  the issuance or sale price from the lowest  exchange  price in
effect as described  above,  such sum  multiplied by (ii) the number shares that
would have been received had the entire  Exchangeable  Note been tendered on the
day immediately  preceding such sale or issuance,  such product divided by (iii)
the  exchange  price in effect  on the day  immediately  preceding  such sale or
issuance.

         Registration.  The Company is required to register and keep  registered
at least 125% of the  aggregate  number of shares of common stock into which the
Exchangeable   Note  is  exchangeable  and  for  which  the  Note  Warrants  are
exercisable.

         Limitation on Shares Issuable: Notwithstanding the registration of such
number of shares,  the Company is subject to the NASD Rule  4460(i)  that limits
the  Company  from  issuing  securities  equal  to or in  excess  of  20% of the
Company's  outstanding  securities on the date immediately prior to the issuance
of the Exchangeable Note and the Note Warrants unless and until the stockholders
approve such an issuance.  The terms of the Exchangeable  Note also provide that
the number of shares  issuable  upon  exchange of the  Exchangeable  Note cannot
exceed 19.9% of the Company's outstanding  securities as of March 22, 1999 until
stockholder approval is received.

         Cash Payments.  Upon the occurrence of certain events,  the Company may
be required to make significant cash payments to the holders of the Exchangeable
Note.  One  such  event is the  failure  to issue  stock  certificates  within 7
business  days of the  exchange  date of all or any portion of the  Exchangeable
Note. The Company must pay  liquidated  damages of $10,000 per day for every day
that that the  certificates  are delayed  beyond the 7 business days allowed for
delivery of the stock certificates.

         Prepayment  and Redemption at the Company's  Option.  On or after March
10,  2000,  the Company may prepay all or any portion of the  Exchangeable  Note
(the "Prepayment  Portion") upon giving at least 20 trading days prior notice to
the  noteholder.  Such notice is irrevocable  and the Company must pay, within 2
business days of the date fixed for  prepayment,  the greater of either (i) 120%
of the  Prepayment  Portion  or (ii) an amount  equal to the number of shares of
common stock into which such Prepayment Portion would be exchangeable multiplied
by the last executed  trade price as reported by Bloomberg  L.P. as of the close
of  normal  trading  hours on the  Nasdaq  National  Market on the  trading  day
immediately  preceding the date of prepayment (either (i) or (ii) referred to as
the  "Prepayment  Amount").  However,  up and until 5 business days prior to the
date fixed for  prepayment,  the  noteholder  may, at its sole option,  submit a
notice of  exchange  in an  exchange  amount  equal to all or any portion of the
Prepayment  Amount and receive the number of shares of common stock issuable for
such exchange amount.

         Change of Control.  Upon a change of control, the Company must offer to
buy the  Exchangeable  Note at the  greater of: (i) 150% of the  principal  plus
accrued and unpaid  interest and penalties or (ii) an amount equal to the number
of shares into which the Exchangeable  Note would be exchangeable  multiplied by
the last executed  trade price as reported by Bloomberg  L.P. as of the close of
normal  trading  hours  on  the  Nasdaq  National  Market  on  the  trading  day
immediately  preceding  the date of the change of  control.  A change of control
includes:  (i) a purchase of a majority of the Company's  common  stock;  (ii) a
merger of the Company with another  entity in which the  Company's  stockholders
own  less  than a  majority  of the  surviving  entity;  (iii)  the  removal  or
replacement  of a majority  of the  members of the Board of  Directors  who were
sitting on the Board at the time of the change of control;  and (iv) the sale of
all or substantially all of the Company's assets to another entity.



<PAGE>



         Right of First Offer.  Until March 15, 2001, the noteholder has a right
of first offer on certain issuances by the Company of equity or debt securities.
Under the right of first offer,  the Company must deliver  written notice to the
noteholder  at least  10  trading  days  prior to the  closing  of any  proposed
offering. The noteholder has an option during the 5 trading day period following
delivery of notice to purchase  up to the full  amount of the  securities  being
offered in the  proposed  offering on the same  terms.  The right of first offer
does not apply to certain issuances by the Company, including: (i) shares issued
to  employees  upon  exercise of options;  (ii) shares  issuable or issued in an
underwritten  public  offering;  (iii) shares issuable in connection with a debt
financing to refinance existing term loans; (iv) shares issuable in an equipment
financing;  and  (v)  shares  issued  in a  joint  venture  or  other  strategic
investment.

         Warrants.  The Note Warrants issued in connection with the Exchangeable
Note have an exercise  price of $3.0375  per share and expire at 5:00 p.m.,  New
York time, on March 10, 2004. The number of shares that may be purchased and the
exercise  price at which shares can be purchased  are both subject to adjustment
upon certain events,  including the payment of dividends or distributions on and
the subdivision,  combination or reclassification of the common stock underlying
the warrants.

         The Note Warrants may be redeemed at any time, at the Company's option,
for $0.10 per share of common  stock  purchasable  if the  closing  price of the
common stock, as reported by Bloomberg L.P. on the applicable  market,  exceeded
$12.00  per share  for a period of 20  consecutive  trading  days and  notice of
redemption  is given to the  warrantholder  within 5 trading  days after such 20
trading  day  period  and no  less  than 30  days  before  the  date  fixed  for
redemption.  However,  the Company's right of redemption is subject to the right
of the warrantholder to exercise the warrants prior to the redemption date.


Description of Certain Provisions of Our Exchangeable Preferred Stock

         On March 22, 1999,  the Company sold 1,500 shares of Series B Preferred
Stock at a price per share of $1,000  and issued  warrants  to  purchase  65,000
shares of the  Company's  common  stock at an exercise  price of $3.82 per share
(subject  to  adjustment)  (the  "B-Warrants").   The  rights,  preferences  and
privileges of the  outstanding  Exchangeable  Preferred  Stock are summarized as
follows:

         Dividend Rights. Cumulative dividends of $30 per year per share must be
paid on the Series B Preferred Stock (3% dividend).  Such dividends accrue daily
and are payable  quarterly  on April 30,  July 31,  October 31 and January 31 of
each year.

         Liquidation Preference.  The Series B Preferred Stock has a liquidation
preference of $1,000 per share plus all accrued but unpaid dividends. In case of
liquidation,  dissolution  or winding up of the  Company,  whether  voluntary or
involuntary,  the  holders of Series B  Preferred  Stock must be paid $1,000 per
share of Series B  Preferred  Stock held prior to the  payment of any amounts to
the holders of common stock.  At the option of each holder of Series B Preferred
Stock, a transaction or series of related transactions in which more than 50% of
the voting power of the Company is disposed of or the  consolidation,  merger or
other business  combination of the Corporation  with or into any other person or
persons when the Company is not the survivor may be deemed a  liquidation  event
upon which the liquidation  preference  amounts must be paid to such holder. The
Series B Preferred Stock ranks pari passu with the Series A Preferred Stock with
regard to liquidation preference.

         Exchange  Price.  Each share of Series B  Preferred  Stock has a stated
value of $1,000 and is  convertible at the election of the holder into shares of
common stock. The actual number of shares of common stock issuable upon exchange
of the Series B Preferred Stock will be determined by the following formula:

     (the number of shares of Series B Preferred Stock tendered for exchange
                              multiplied by $1,000)

                                   divided by

            (the applicable exchange price at the time of exchange).

         The exchange  price is subject to  adjustment.  On or before August 19,
1999, the exchange  price of the Series B Preferred  Stock is equal to $3.57 per
share.  Thereafter,  the exchange price of the Series B Preferred Stock is equal
to the  lesser  of (a)  $3.57  per  share  or (b) the  average  of the 2  lowest
consecutive closing bid prices of the common stock as reported by Bloomberg L.P.
for  the 20  consecutive  trading  days  immediately  preceding  the  applicable
conversion date discounted by 15%.

         The  following  table sets  forth the number of shares of common  stock
issuable  upon exchange of the Series B Preferred  Stock.  It assumes the market
price of the common stock is 25%, 50%, 75%,  100%,  125% and 150% of the closing
price of the common  stock on April 26,  1999,  which was  $3.125 per share.  It
further  assumes the exchange  takes place after August 19, 1999 at the required
exchange price of 85% of the closing price, except where the closing price is at
or above $3.57, in which case the exchange price is $3.57.

                           Percent of                Number of Shares
                          Market Price            Issuable Upon Exchange

                               25%                      2,258,824
                               50%                      1,129,412
                               75%                        752,941
                              100%                        564,706
                              125%                        420,168
                              150%                        420,168


         In  addition,  the  exchange  price of the Series B Preferred  Stock is
subject to adjustment  upon the  occurrence  of certain other events,  including
stock  splits,  stock  dividends,  combinations  or  other  similar  events.  No
adjustment will be made for dividends (other than stock dividends), if any, paid
on the common stock.

         If the applicable  exchange  price is less than $7.00,  the Company has
the  option to pay cash to any holder of Series B  Preferred  Stock in an amount
equal to the closing ask price on the principal market in which the common stock
is trading on the  exchange  date  multiplied  by the number of shares of common
stock which would have been issuable upon an exchange.  This cash payment may be
made in lieu of issuing  shares of common stock upon an exchange.  However,  the
Company must have given notice of such an election prior to or within 2 hours of
receipt of a notice of exchange from any holder of Series B Preferred Stock.

         Registration.  The Company is required to register and keep  registered
at least 167% of the  aggregate  number of shares of common stock into which the
Series B  Preferred  Stock is  exchangeable  and for  which the  B-Warrants  are
exercisable.

         Limitation  on Shares  Issuable.  The terms of the  Series B  Preferred
Stock  financing  agreements  prohibit the Company from issuing shares of common
stock upon exchange of the shares of Series B Preferred Stock or exercise of the
B-Warrants if such issuance  would result in any holder  beneficially  owning in
excess of 9.9% of the  Company's  then-outstanding  common stock.  However,  the
determination as to whether any holder's  ownership  exceeds that limit is to be
made solely by such holder of Series B Preferred Stock,  not by the Company.  In
addition,  the  Company  is  subject to the NASD Rule  4460(i)  that  limits the
Company from issuing  securities  equal to or in excess of 20% of the  Company's
outstanding  securities  on the date  immediately  prior to the  issuance of the
Series B  Preferred  Stock and  B-Warrants  unless  and  until the  stockholders
approve such an issuance. The terms of the Series B Preferred Stock also provide
that the number of shares issuable upon exchange of the Series B Preferred Stock
cannot  exceed 19.9% of the Company's  outstanding  common stock as of March 22,
1999 until stockholder approval is received.

         Mandatory  Exchange.  At any time on or after August 20,  1999,  if the
average of the closing bid prices for the 5 consecutive trading days is at least
$7.00 per share,  the  Company can require all holders of the Series B Preferred
Stock to convert  their shares into shares of common  stock  (subject to certain
limits) or, at the option of the  Company,  buy out all such  holders in cash at
the  then-effective  exchange  price.  The Company  must  provide no more than 3
trading days' written  notice of such mandatory  exchange or mandatory  buy-out.
The Series B  Preferred  Stock is subject to  mandatory  conversion  on or after
March 22, 2002.

         Redemption.  At any time upon the earlier of (i) an underwritten public
offering of the Company's  common stock or (ii)  September 22, 1999, the Company
may, at its option,  redeem the shares of Series B Preferred Stock at a price of
140% of the original  purchase price of $1,000 per share plus accrued and unpaid
dividends.

         If the Company ceases to be listed on a national  securities  exchange,
the Nasdaq  National  Market or the OTC  Bulletin  Board,  then the Company must
redeem all shares of Series B Preferred  Stock at 115% of the original  purchase
price of $1,000 per share plus accrued and unpaid dividends.

         Cash Payments. Upon the occurrence of certain other events, the Company
may be required to make significant cash payments to the holders of the Series B
Preferred Stock.  Such events include,  but are not limited to the late issuance
or delivery of stock certificates upon an exchange of shares.

         If stock  certificates  are not issued  within 3  business  days of any
exchange  date,  the Company must pay  liquidated  damages of $100 per $5,000 of
liquidation  amount of Series B Preferred  Stock being  exchanged  for the first
business day the  certificates are late. The damages increase by $100 per $5,000
liquidation  amount per day late  (i.e.,  $500 per $5,000 on the fifth late day)
and are $1,000 plus $200 per day after 10 days.

          If the Company is required to honor any and all  requests for exchange
of the Series B Preferred  Stock which would  result in the issuance of a number
of shares of common  stock  equal to or in excess of 20% of the shares of common
stock which were issued and outstanding on the dates of issuance of the Series B
Preferred Stock and B-Warrants but fails to receive stockholder approval of such
an  issuance,  the Company  must pay in cash an amount  equal to the closing ask
price on the  principal  market in which the common stock is trading on the date
of exchange  multiplied by the number of shares of common stock which would have
been  issuable  upon  exchange.  In addition,  if such cash amounts are not paid
within 3 days of the exchange date,  the Company must pay liquidated  damages in
the same amounts as set forth above for the late issuance of stock certificates.

         Protective  Provisions.  The Series B Preferred  Stock ranks pari passu
with the Series A Preferred Stock and senior to the common stock with respect to
the right to receive dividend payments and liquidation preferences. The Series B
Preferred Stock has no voting rights, except as otherwise provided by applicable
law or pursuant to certain contractual protections described herein. The Company
is  prohibited  from,  among  other  things,  altering,  changing  or  otherwise
adversely  affecting  the terms of the Series B  Preferred  Stock,  creating  or
issuing any senior  securities,  increasing the  authorized  number of shares of
Series B Preferred  Stock,  and acting so as to generate  taxation under Section
305 of the  Internal  Revenue  Code  of  1986,  as  amended.  In  addition,  any
modification  of the rights of Series B Preferred Stock requires the vote of 85%
of the shares of Series B Preferred Stock outstanding.

         Change of Control.  The Company is prohibited from effecting any merger
or consolidation  with or into, or transferring all or substantially  all of the
assets of the Company to another entity,  unless the resulting entity assumes in
writing,  or by operation of law, the  obligations to deliver shares of stock or
securities to the holders of Series B Preferred Stock or B-Warrants.

         Warrants.  The  B-Warrants  issued  in  connection  with  the  Series B
Preferred  Stock have an exercise price of $3.82 per share.  The warrants become
exercisable  on September 15, 1999 and expire on September 15, 2002.  The number
of shares that may be purchased  and the  exercise  price at which shares can be
purchased  are both subject to  adjustment  upon certain  events,  including the
payment of dividends or  distributions  on and the  subdivision,  combination or
reclassification of the common stock underlying the warrants.

         Item 15. Indemnification of Directors and Officers

         Under  Section  145 of the  Delaware  General  Corporation  Law, we can
indemnify our directors and officers against  liabilities they may incur in such
capacities,  including  liabilities under the Securities Act. Our Bylaws provide
that  we will  indemnify  our  directors  and  officers  to the  fullest  extent
permitted by law and require us to advance  litigation  expenses upon receipt by
us of an  undertaking by the director or officer to repay such advances if it is
ultimately   determined  that  the  director  or  officer  is  not  entitled  to
indemnification. The Bylaws also provide that rights conferred under such Bylaws
do not exclude any other right such persons may have or acquire under any bylaw,
agreement,  vote  of  stockholders  or  disinterested  directors  or  otherwise.
Furthermore,  under our  Bylaws,  we may  purchase  and  maintain  insurance  to
indemnify directors and officers in instances in which they may not otherwise be
indemnified by us.

         Our Certificate of Incorporation provides that, under Delaware law, our
directors shall not be liable for monetary  damages for breach of the directors'
fiduciary  duty  of  care  to us and our  stockholders.  This  provision  in the
Certificate  of  Incorporation  does not  eliminate  the  duty of  care,  and in
appropriate  circumstances  equitable remedies such as injunctive or other forms
of  non-monetary  relief will remain  available under Delaware law. In addition,
each  director  will  continue  to be  subject  to  liability  for breach of the
director's duty of loyalty to us or our stockholders,  for acts or omissions not
in good faith or involving intentional  misconduct or knowing violations of law,
for  actions  leading to  improper  personal  benefit to the  director,  and for
payment of dividends or approval of stock  repurchases or  redemptions  that are
unlawful  under  Delaware law. The  provision  also does not affect a director's
responsibilities  under any other law,  such as the federal  securities  laws or
state or federal environmental laws.

Item 17. Undertakings

         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, as amended; (ii) To reflect in the
                  prospectus  any facts or events  arising  after the  effective
                  date of  this  registration  statement  (or  the  most  recent
                  post-effective amendment hereof) which, individually or in the
                  aggregate,  represent a fundamental  change in the information
                  set forth in this registration statement.  Notwithstanding the
                  foregoing,  any  increase or decrease in volume of  securities
                  offered (if the total dollar value of securities offered would
                  not exceed that which was  registered)  and any deviation from
                  the low or high end of the estimated  maximum  offering  price
                  may be  reflected  in the form of  prospectus  filed  with the
                  Commission under Rule 424(b) if, in the aggregate, the changes
                  in volume and price represent no more than a 20 percent change
                  in the  maximum  aggregate  offering  price  set  forth in the
                  "Calculation  of  Registration  Fee"  table  in the  effective
                  registration  statement;  and (iii) To  include  any  material
                  information  with  respect  to the  plan of  distribution  not
                  previously  disclosed  in this  registration  statement or any
                  material  change  to such  information  in  this  registration
                  statement.

         Provided,  however,  that paragraphs (1)(i) and (1)(ii) do not apply if
the information  required to be included in a post-effective  amendment by those
paragraphs  is contained in periodic  reports filed by us pursuant to Section 13
or Section 15(d) of the  Securities  Exchange Act of 1934, as amended,  that are
incorporated by reference in this registration statement.

         (2) That,  for the  purpose  of  determining  any  liability  under the
Securities Act, each such  post-effective  amendment shall be deemed to be a new
registration  statement  relating  to the  securities  offered  herein,  and the
offering of such  securities at that time shall be deemed to be the initial bona
fide offering thereof.

         (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  that, for purposes of
determining any liability under the Securities Act, each filing of Alyn's Annual
Report  under  Section  13(a)  or  Section  15(d)  of the  Exchange  Act that is
incorporated by reference into this registration statement shall be deemed to be
a new registration  statement relating to the securities offered herein, and the
offering of such  securities at that time shall be deemed to be the initial bona
fide offering thereof.

         Insofar as indemnification for liabilities arising under the Securities
Act of 1933 may be permitted to directors,  officers and controlling  persons of
Alyn pursuant to the foregoing  provisions,  or otherwise,  we have been advised
that  in  the  opinion  of  the   Securities   and  Exchange   Commission   such
indemnification  is against public policy as expressed in the Securities Act and
is,  therefore,  unenforceable.  In the event  that a claim for  indemnification
against such liabilities (other than the payment by Alyn of expenses incurred or
paid by a  director,  officer or  controlling  person of Alyn 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,  we will, unless in the opinion of our counsel the question has been
settled by controlling precedent,  submit to a court of appropriate jurisdiction
the question  whether such  indemnification  by us is against  public  policy as
expressed in the Securities  Act and will be governed by the final  adjudication
of such issue.

events or developments which hereafter may be brought to our attention and which
