                                   THE COMPANY

         Telegen Corporation ("Telegen" or the "Company") is a diversified, high
technology  company with  products,  both developed and in  development,  in the
telecommunications,  Internet  hardware  and  flat  panel  display  markets.  At
present,  Telegen is organized into two subsidiaries  and one division.  Telegen
Display  Laboratories,  Inc. ("TDL"), a California  corporation and a controlled
second tier  subsidiary  of the  Company,  has  developed a low-cost  flat panel
technology  to  compete  with  other  types  of  flat  panel  displays.  Telegen
Communications  Corporation ("TCC"), a California corporation and a wholly-owned
subsidiary of the Company, develops,  manufactures and markets Internet products
and a line of intelligent  telecommunications  which provide additional features
to existing  telephone  equipment  used by consumers and small  businesses.  The
Company has entered  into a binding  letter of intent with an  affiliate  of the
Company on February 25, 1998 for the sale of substantially all the assets of TCC
and intends to complete such sale shortly after the filing of this  Registration
Statement.  The Telegen Laboratories  division is a research  organization which
develops new products and technologies  which are then manufactured and marketed
through one of the  operating  divisions or  subsidiaries.  Telegen's  corporate
offices are located at 101 Saginaw Road, Redwood City, CA 94063, (650) 261-9400.

         Common  Stock  Subscription.  In August 1997,  the Company  initiated a
private offering on a subscription  basis of 222,222 shares of its common stock,
no  par  value  (the  "Common  Stock")  to  accredited  investors  (the  "Common
Investors"),  as that term is defined in Rule  501(a) of the  Securities  Act of
1933,  as amended  (the  "Act"),  at a  per-share  price of $2.25  (the  "Common
Offering"). As of September 30, 1997, the Company had closed the Common Offering
and had sold 220,404 shares of Common Stock pursuant thereto.

         In connection with the Common  Offering,  the Company also delivered to
certain of the Common  Investors an aggregate of 50,000 warrants to purchase one
share of Common Stock at a $0.01 per share (each a "0.01  Warrants").  The $0.01
Warrant  have a  four-year  term from the date of issuance  and are  exercisable
immediately  upon  issuance.  The Company has the right to force the exercise of
the $0.01 Warrants at any time after their issuance.

         On March 19, 1998, the Company made  available to the Common  Investors
an exchange offer for the Common Stock purchased thereby (the "Exchange Offer").
Under  the  Exchange  Offer,  the  Common  Investors  were  offered  convertible
subordinated promissory notes (the"Notes") for their shares of Common Stock with
a face value equal to the number of shares of Common  Stock  tendered  under the
Exchange  Offer  multiplied  by the five-day  average of the  Company's  closing
trading  prices  on the  OTC  Bulletin  Board  prior  to  March  17,  1998  (the
"Conversion  Price").  The Notes have a one-year  term with a six  percent  (6%)
balloon  interest  payment due at the end of the term of the Note. The Notes are
subordinated  to all other  existing  debt of the  Company,  both as to interest
payment and upon liquidation.  The Notes are also convertible to Common Stock at
any time by a holder  thereof,  such  number of  Shares  of  Common  Stock to be
determined  by  dividing  the amount of face value of the Note  tendered  by the
Conversion  Price.  The  Company  may prepay the Notes at any time after  giving
fifteen (15) days prior written notice to holders thereof.

         Under the Exchange  Offer,  109,293  Shares were exchanged for Notes by
the Common  Investors.  The Notes issued to the Common Investors are "restricted
securities" as that term is defined in Rule 144

                                        4

<PAGE>


of the Act ("Rule  144").  The  Registration  Statement  is used to register the
issuance of Common Stock, if any, upon conversion of the Notes and upon exercise
of the Warrants.

         Common Stock and  Warrants  Subscription.  On October 7, 1997,  Telegen
initiated a private  offering  on a  subscription  basis of up to 500,000  units
(each, a "Unit") to accredited investors (the "Unit Investors"), as that term is
defined in Rule 501(a) of the Act, with a purchase  price per Unit of $2.00 (the
"Unit  Offering").  Each Unit consisted of (i) one share of Common Stock, (ii) a
$0.01 Warrant, and (iii) a warrant to purchase one share of the Company's Common
Stock at a $4.00 per share exercise  price (each,  a "$4.00  Warrant," the $0.01
Warrants and the $4.00 Warrants are collectively the "Warrants").  As of October
21, 1997 the Unit Offering was fully  subscribed.  As part of the  consideration
for placing the Units and for fully  subscribing the Unit Offering,  the Company
issued Capitol Bay  Securities,  the placement  agent for the Offering  ("CBS"),
50,000 $0.01 Warrants.

         Units  purchased  under the Unit Offering and the $0.01 Warrants issued
to CBS are subject to lock up provisions  which limit the ability of a holder of
Common Stock or to sell Common Stock received upon exercise of the Warrants. The
purchased  Units are divided into four (4) equal groups (each, a "Group"),  each
having a separate lock-up period (the "Lock-Up Period") for the resale of Common
Stock purchased and the sale of Common Stock upon exercise of the Warrants.  The
Lock-Up Period for each Group expires on January 1, 1998, April 1, 1998, July 1,
1998 and October 1, 1998, respectively.

         The $4.00  Warrants have a four-year term from the date of issuance and
are exercisable  immediately  upon issuance.  The Company has the right to force
the exercise of the $4.00 Warrants  after the Company's  Common Stock trades for
twenty (20) trading days at $6.00 or more.

         The Company made the Exchange  Offer  available to the Unit  Investors.
Under the Exchange  Offer,  800,000  Shares were exchanged for Notes by the Unit
Investors.  The Notes and the Warrants issued to CBS are "restricted securities"
as that term is  defined  in Rule 144.  The  Registration  Statement  is used to
register the issuance of the Common Stock,  if any, to the Unit  Investors  upon
conversion of the Notes and upon exercise of the Warrants.

         TSC Block Purchase.  On October 23, 1997, TSC, LLC, a Delaware  limited
liability  company  ("TSC")  entered into an amended and restated stock purchase
agreement with Jessica L. Stevens,  an affiliate of the Company  ("Stevens") for
the  purchase of 550,000  shares of Common Stock in a private  transaction.  The
purchase  price for each share of Common Stock under the Purchase  Agreement was
$1.73  for a total  purchase  price of  $951,500  payable  $250,000  in cash and
$701,500 in the form of a promissory  note.  The Company made the Exchange Offer
available to TSC which converted 550,000 Shares of Common Stock held thereby for
the Notes.  The Notes held by TSC are  "restricted  securities"  as that term is
defined in Rule 144 and this  Registration  Statement  is used to  register  the
issuance of Common  Stock,  if any, to TSC upon the  conversion of such Notes by
TSC.

         Convertible Promissory Notes and Warrants Subscription. On November 26,
1997,  Telegen initiated a private offering on a subscription  basis of up to 20
units (each, a "Note Unit") to accredited investors (the "Note Unit Investors"),
as that term is defined  in Rule  501(a) of the Act,  with a purchase  price per
Unit of $50,000 (the "Note Unit  Offering").  Each Note Unit  consisted of (i) a
convertible  promissory  note with a face value of $50,000  (each a "Unit Note")
and (ii) a warrant to purchase 10,000

                                        5

<PAGE>


shares of Common  Stock,  at a $2.25 per  share  exercise  price  (each a "$2.25
Warrant").  As of November  26, 1997,  the Company sold ten (10) Note Units.  As
part of the  consideration  for placing the Note Units,  Capitol Bay Securities,
the  Company's  placement  agent for the Units  ("CBS")  received  a warrant  to
purchase  80,000  shares of Common Stock for every  $500,000 of Note Units sold;
such warrant has the same terms as the $2.25 Warrants.

         Each  Unit Note has an  18-month  term  from the date of  issuance  and
carries simple interest at 6% per annum,  payable at the Company's discretion in
cash or stock and is convertible  into Common Stock at a conversion price of the
lesser of (i) $2.75 or (ii)  seventy-five  percent  (75%) of the  lowest  NASDAQ
trading price over a five (5), ten (10) or twenty  (20)-day  period prior to the
date of  conversion,  as applicable,  depending upon the date of conversion.  At
maturity each Note  automatically  converts to Common Stock.  Each $2.25 Warrant
has a  four-year  term from  issuance,  is  immediately  exercisable  and may be
exercised on a "cashless" or "net-exercise" basis.

         The Unit Notes and the $2.25  Warrants are  "restricted  securities" as
that  term is  defined  in Rule 144 and the  Registration  Statement  is used to
register the issuance of Common Stock,  if any, to the Note Unit  Investors upon
conversion  of the Notes to Common  Stock and the  issuance of Common Stock upon
exercise of the $2.25 Warrants.

                                  RISK FACTORS

         In addition to the other information in this Prospectus,  the following
factors should be considered carefully in evaluating an investment in the shares
of Common Stock offered by this  Prospectus.  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  herein.
Factors that could cause or contribute to such differences  include, but are not
limited to, those discussed in "Risk Factors" and "The Company" as well as those
discussed elsewhere in this Prospectus.

Telegen's Capital Needs

         Telegen's  current working  capital is very limited.  The Company has a
limited amount of readily  available  funds to cover  immediate  working capital
needs such as employee  wages,  wage taxes,  social  security  taxes,  and lease
payments.  As of approximately  February 20, 1998, the Company has ceased to pay
its current  employees.  The Company owes additional  wages to its TCC employees
which the  Company  expects to be paid by the  purchaser  of TCC  pursuant  to a
letter of intent (see below), whereby such purchaser will assume the outstanding
TCC wage  obligations of the Company and offer employment to such TCC employees.
Furthermore,  the Company  currently has tax debts  associated  with federal and
state  wage  withholding  taxes  and  social  security  taxes in the  amount  of
$350,000.  Under the letter of intent to sell the assets of TCC, the  purchasers
of TCC will assume $100,000 of such liabilities.  To meet such immediate working
capital needs, the Company will need to raise immediate  funds,  whether through
the sale of the  Company's  assets or through  attracting  immediate  financing.
There can be no  assurance  that the Company will be able to obtain such funding
on acceptable  terms,  or if at all to meet its immediate  capital  demands.  If
adequate  funds  are not  available  as  required,  Telegen  will not be able to
continue operations.

         Assuming  Telegen can obtain  adequate  short-term  capital,  Telegen's
future capital requirements will depend upon many factors,  including the extent
and timing of  acceptance of Telegen's  products in the market,  the progress of
Telegen's research and development,  Telegen's  operating results and the status
of competitive products.  Additionally,  Telegen's general working capital needs
will depend upon numerous factors,  including the progress of Telegen's research
and development  activities,  the cost of increasing Telegen's sales,  marketing
and  manufacturing   activities  and  the  amount  of  revenues  generated  from
operations.  Although  Telegen  believes it will obtain  significant  additional
funding  through  1998,  there can be no assurance  that Telegen will be able to
obtain such funding or that it will not require additional  funding, or that any
additional financing will be available to Telegen on acceptable terms, if at all
to meet its capital demands through 1998. If adequate funds are not available as
required, Telegen's results of operations will be materially adversely affected.

         Telegen   believes   it  requires   substantial   capital  to  complete
development of a finished  prototype of the HGED flat panel display  technology,
and that additional capital will be needed to establish a high volume production
capability.  There can be no assurance  that any  additional  financing  will be
available to Telegen on acceptable  terms,  if at all. If adequate funds are not
available  as  required,  Telegen's  results of  operations  from the flat panel
technology will be materially adversely affected.

History of Telegen Operating Losses; Accumulated Deficit and Minimum Revenues

         Telegen's   predecessor,   now   an   operating   subsidiary,   Telegen
Communications  Corporation  ("TCC"), was incorporated in 1990 and first shipped
products  in 1991.  Telegen  has been  engaged  in  lengthy  development  of its
products and has incurred significant operating losses in every fiscal year

                                        7

<PAGE>


since its  inception.  The  cumulative  net loss for the period  from  inception
through  September  30,  1997 was  $18,404,757.  In order to become  profitable,
Telegen must increase sales of its existing products, develop, commercialize and
sustain volume  manufacturing  of its flat panel products,  develop new products
for new and  existing  markets,  manage its  operating  expenses  and expand its
distribution  capability.  There can be no assurance  that Telegen will meet and
realize these objectives or ever achieve profitability.

Litigation

         The  Company  and its  Telegen  Display  Laboratories  Inc.  subsidiary
("TDL") are named defendants in a complaint (the  "Complaint")  filed January 7,
1998 in  Superior  Court,  San Mateo  County,  filed by IPC  Corporation,  Ltd.,
Transtech   Electronics,   PTE,  LTD.,  and  IPC  Transtech   Display  PTE,  LTD
(collectively,  the  "Plaintiffs").  The  Complaint  alleges  that  the  Company
committed material  misrepresentations when the Company sold TDL Common Stock to
the  Plaintiffs  for  $5,000,000 on May 30, 1996.  Additional  named  defendants
include Jessica L. Stevens,  Warren M. Dillard, Bonnie Crystal, and William J.P.
Weiland, all former officers of the Company. The Plaintiffs seek recision of the
original purchase,  complete restitution of the $5,000,000,  interest,  punitive
damages,  costs and attorneys' fees. Neither the Company nor TDL has been served
with the Complaint and no action has been  initiated  against the Company beyond
filing the Complaint.  The Company  believes that the Complaint is without merit
and intends to vigorously  defend such matter. To the extent the Plaintiffs were
to  succeed  in this  matter,  Telegen's  results of  operations  and  financial
condition would be materially adversely affected.

Telegen's Exposure to Technological and Market Change;  Difficulty in Developing
Flat Panel Technology

         The  market  for   Telegen's   products  is   characterized   by  rapid
technological  change and evolving industry  standards and is highly competitive
with  respect  to  timely  product  innovation.  The  introduction  of  products
embodying new technology and the emergence of new industry  standards can render
existing products obsolete and unmarketable. Telegen's success will be dependent
in part upon its  ability to  anticipate  changes  in  technology  and  industry
standards and to successfully develop and introduce new and enhanced products on
a timely basis. If Telegen is unable to do so,  Telegen's  results of operations
will be materially adversely affected.

         With regard to its flat panel display technology,  there are other more
developed  and accepted flat panel  display  technologies  already in commercial
production  which will compete with  Telegen's  technology.  The Company has not
finished the development of a completed prototype of the HGED flat panel display
technology.  The Company believes it can successfully  scale its HGED flat panel
display technology to 10.5 inch diagonal displays.  At present, the Company does
not believe that  scalability of this  generation of its technology  beyond such
levels is feasible.  However,  the Company does have preliminary design concepts
for a  second  generation  of its  technology  which  might  provide  additional
scalability.  There can be no assurance  that Telegen will be  successful in the
development  of its flat panel  technology  or that Telegen  will not  encounter
technical or other serious difficulties in its development, commercialization or
volume  manufacturing  which would be materially adverse to Telegen's results of
operations.

Telegen's Dependence Upon Key Personnel

         Telegen's  future  success  will  depend in  significant  part upon the
continued service of certain key technical and senior management personnel,  and
Telegen's ability to attract,  assimilate and retain highly qualified technical,
managerial and sales and marketing personnel.  Competition for such personnel is
intense,  and there can be no assurance that Telegen can retain its existing key
managerial,  technical or sales and marketing  personnel or that it can attract,
assimilate and retain such employees in the future. The loss of key personnel or
the inability to hire,  assimilate or retain  qualified  personnel in the future
could have a material adverse effect upon Telegen's results of operations.

         Telegen has entered into agreements with each of its executive officers
(as  well  as  all  other  full-time  employees)  that  prohibit  disclosure  of
confidential information to anyone outside of Telegen both during and subsequent
to  employment  and  require   disclosure  and  assignment  to  Telegen  of  all
proprietary  rights to any  ideas,  discoveries  or  inventions  relating  to or
resulting from the officer's work for Telegen.

Competition in the Telecommunications Market

         The market for telephone peripheral equipment is highly competitive, is
dominated by successful  niche marketers and Telegen expects this competition to
continually increase. There are a number of companies which develop, manufacture
and sell telecommunications  devices which perform some of the same functions as
those of Telegen's products. There can be no assurance that Telegen will be able
to  compete  effectively  against  its  competitors,   many  of  whom  may  have
substantially  greater financial  resources than Telegen.  Further,  some of the
telephone call routing  functions of Telegen's  products can be provided through
reprogramming  by Bell Operating  Companies of their central office equipment to
allow "equal  access" by customers to the long distance  carrier of their choice
without  "dialing  around" by inserting an access code. Since this "dial around"
process is the principal  function of Telegen's ACS 2000 and MLD 1000  products,
if such an "equal access" feature were introduced,  demand for Telegen's present
products would be seriously impaired.

TCC's Dependence on Major Customers

         Telegen  expects  that a large  proportion  of its  revenues  from  its
telecommunications  products  will be realized  from sales to a small  number of
companies,  primarily  the major  long  distance  carriers,  the  Regional  Bell
Operating Companies, as well as other nationwide  distributors.  The loss of one
or more of these relationships,  when developed,  could have a material negative
effect on Telegen's results of operations.

         During 1995, three customers  accounted for  approximately 82% of TCC's
revenues:  Bell Atlantic,  Synernet and Sprint. Of these,  Bell Atlantic,  which
purchased TCC's Teleblocker product,  made up 45% of TCC's total sales for 1995.
The removal of the Teleblocker  product from the market in 1996 due to redesign,
effectively  eliminated sales to Bell Atlantic and significantly  affected total
sales for TCC for 1996.

                                        9

Flat Panel Competition; Flat Panel Patent(s)

         The market for flat  panel  displays  is  dominated  by major  Japanese
companies  such as Sharp  Electronics,  Toshiba and Sony.  Telegen  expects this
competition to continually increase. There can be no assurance that Telegen will
be able to compete  effectively  against its competitors,  many of whom may have
substantially  greater  financial  resources  than Telegen.  Flat panel displays
manufactured  utilizing  AMLCD  technology have been in production for almost 10
years and have proven market acceptance. New technologies, such as FED and Color
Plasma,  are in development by a number of potential  competitors,  some of whom
have greater financial  resources than Telegen.  Telegen does not own or lease a
manufacturing   facility   for,  and  has  not  begun  the  process  of,  volume
manufacturing  of flat panel displays.  There can be no assurance that Telegen's
HGED technology can compete successfully on a cost or display quality basis with
these other  technologies.  Further,  there can be no assurance  that  Telegen's
efforts to obtain patent  protection for its HGED  technology will be successful
or, if patent  protection is obtained,  that  Telegen's  patent(s)  will provide
adequate protection.

Telegen's Dependence Upon Limited Number of Manufacturing  Sources and Component
Suppliers

         Telegen currently relies upon a limited number of manufacturing sources
for its telecom production capability.  Although Telegen is currently seeking to
qualify  alternative  sources  of supply,  Telegen  has not yet  contracted  for
alternative suppliers to perform such manufacturing  activities. In the event of
an  interruption  of  production or delivery of supplies,  Telegen's  ability to
deliver its products in a timely  fashion would be  compromised,  which would be
materially  adverse to Telegen's results of operations.  Certain components used
in Telegen's telecommunications products, such as microprocessors, are available
from only a limited  number of sources.  Although to date Telegen has  generally
been able to obtain adequate supplies of these components, Telegen obtains these
components on a purchase order basis and does not have long-term  contracts with
any of these suppliers.  In addition, some suppliers require that Telegen either
pre-pay the price of  components  being  purchased or  establish an  irrevocable
letter of credit for the amount of the purchase. Telegen anticipates that, as it
begins  manufacture of other  products,  it will encounter  similar  limitations
regarding the components for those products.  Telegen's  inability in the future
to obtain sufficient  limited-source  components for its  telecommunications and
other products,  or to develop  alternative  sources,  could result in delays in
product  introductions or shipments,  which could have a material adverse effect
on Telegen's results of operations.

Telegen's Need to Develop Marketing Experience

         Telegen has  limited  marketing  experience,  and  expanding  Telegen's
markets will require  significant  expenses,  including  additions to personnel.
There can be no  assurance  that  Telegen  will have all the  capital  resources
necessary  to expand  its  sales and  marketing  operations,  or that  Telegen's
attempts to expand its sales and marketing efforts will be successful.

                                       10

Intellectual Property

         Telegen  relies on a  combination  of patents,  trade  secret and other
intellectual  property  law,  nondisclosure   agreements  and  other  protective
measures to preserve its rights  pertaining  to its products.  Such  protection,
however,  may not preclude competitors from developing products similar to those
of Telegen.  In addition,  the laws of certain foreign  countries do not protect
Telegen's  intellectual property rights to the same extent as do the laws of the
United States. There can also be no assurance that third parties will not assert
intellectual  property  infringement claims against Telegen. One such matter was
recently  dismissed  without  prejudice to the Company but there is no assurance
that more claims will not be initiated  from  litigants with more resources than
Telegen.  There is no assurance  that  Telegen  will prevail in such  litigation
seeking damages or an injunction  against the sale of Telegen's products or that
Telegen will be able to obtain any necessary  licenses on reasonable terms or at
all.

Listing of the Company's Stock on the OTC Bulletin Board

         The Company  currently  trades its stock on the OTC Bulletin Board (the
"OTC  BB").  The  OTC  BB  is  a  real-time  electronic  quotation  service  for
over-the-counter securities. The OTC BB is not an automated quotation system and
is characterized by low volume of trading. There is no assurance that the OTC BB
can or will  provide  sufficient  liquidity to holders of the  Company's  Common
Stock.  The Company was trading on the Nasdaq  SmallCap Market until January 22,
1998 and intends to return to it as soon as it meets the listing and maintenance
requirements.  On February 22, 1998,  Nasdaq raised such listing and maintenance
requirements.  There can be no assurance that trading on the OTC BB will provide
investors  with  sufficient  liquidity  for the  purchase and sale of the Common
Stock or that the Company will be able to meet the higher Nasdaq SmallCap Market
("SmallCap") listing and maintenance requirements that have been in effect since
February 22, 1998, in the near future, or if at all, or that if the Company does
meet the SmallCap  requirements  that a broad trading market will develop in the
Common Stock.

ITEM 14.          OTHER EXPENSES OF ISSUANCE AND DISTRIBUTION

         The following table sets forth the various expenses,  all of which will
be paid by the Registrant in connection  with the sale and  distribution  of the
securities being registered,  other than underwriting discounts and commissions,
if any. All of the amounts shown are estimates except the SEC registration fee.


SEC registration fee .............................................       $   689
Legal fees and expenses ..........................................       $20,000
Accounting fees and expenses .....................................       $ 9,000
Transfer agent's and registrar's fees and expenses ...............       $ 1,000
Miscellaneous expenses ...........................................       $ 4,311
                                                                         -------
Total                                                                    $35,000
                                                                         =======

ITEM 15.          INDEMNIFICATION OF DIRECTORS AND OFFICERS

         Section 317 of the California  Corporations  Code authorizes a court to
award,  or a corporation's  Board of Directors to grant,  indemnity to directors
and officers in terms  sufficiently broad to permit such  indemnification  under
certain  circumstances  for liabilities  (including  reimbursement  for expenses
incurred)  arising under the Securities Act. Article V of the Company's  Amended
Articles of  Incorporation  and Article VI of the Company's  Bylaws  provide for
indemnification  of its directors,  officers,  employees and other agents to the
maximum extent permitted by the California  Corporations Code. In addition,  the
Company  has entered  into  indemnification  agreements  with its  officers  and
directors.

         Insofar as indemnification for liabilities arising under the Securities
Act may be  permitted to  directors,  officers  and  controlling  persons of the
Company  pursuant to the California  Corporation  Law and Bylaws of the Company,
the Company has been informed 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.

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:

                           a. To  include  any  prospectus  required  by Section
10(a)(3) of the Securities Act;

                           b. 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; and

                           c. To include any material  information  with respect
to the  plan  of  distribution  not  previously  disclosed  in the  Registration
Statement  or any  material  change  to  such  information  in the  Registration
Statement;  provided, however, that paragraphs (a) and (b) above 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 the Company  pursuant to
Section 13 or Section 15(d) of the  Securities  Exchange Act of 1934, as amended
(the  "Exchange  Act") that are  incorporated  by reference in the  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 therein,  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.

                  4. That, 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.

         Insofar as indemnification for liabilities arising under the Securities
Act may be  permitted to  directors,  officers  and  controlling  persons of the
Registrant pursuant to the foregoing  provisions,  or otherwise,  the Registrant
has been advised that in the opinion of the 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 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  Securities  Act and will be  governed by the final
adjudication of such issue.

      RE:  Registration Statement on Form S-3

Ladies and Gentlemen:

      We have examined the registration statement on Form S-3 to be filed by you
with the  Securities  and  Exchange  Commission  on or about March 24, 1997 (the
"Registration  Statement"),  in  connection  with  the  registration  under  the
Securities  Act of 1933,  for the issuance of  4,734,662  shares of common stock
upon  exercise of certain  Warrants  and upon  conversion  of certain  Notes (as
defined  in the  Registration  Statement)  (the  "Conversion  Shares").  As your
counsel,  we have  examined the  transactions  taken and proposed to be taken in
connection with the issuance of the Conversion Shares to the Security Holders in
the manner set forth in the Registration Statement.

      It is our opinion that the Conversion  Shares will be  legally and validly
issued, fully paid and nonassessable.

      We  consent to the use of this  opinion as an exhibit to the  Registration
Statement,  and further consent to the use of our name wherever appearing in the
Registration  Statement,  including the Prospectus  constituting a part thereof,
and any amendment thereto.

                                           Very truly yours,

                                           Wilson Sonsini Goodrich & Rosati

                       CONSENT OF INDEPENDENT ACCOUNTANTS

We consent to the  incorporation by reference in the  registration  statement of
Telegen  Corporation  on the Form S-3 (dated March 24, 1998) of our report dated
March 21,  1997,  on our  audits of the  consolidated  financial  statements  of
Telegen  Corporation  as of December 31, 1996 and 1995,  and for the years ended
December 31 1996,  1995, and 1994, which report is included in the Annual Report
on Form 10-K.  We also  consent to the  reference  to our firm under the caption
"Experts".
