in the Notice of Exercise (such  aggregate  Exercise  Price the "Total  Exercise
Price").  The Total Exercise Price shall be paid by check or wire transfer.  The
Person or Person(s) in whose name(s) any certificate(s) representing the Warrant
Shares  which are  issuable  upon  exercise of this  Warrant  shall be deemed to
become the  holder(s)  of, and shall be treated  for all  purposes as the record
holder(s) of, such Warrant  Shares,  and such Warrant  Shares shall be deemed to

                  (b) Certificate  Legends.  This Warrant,  all shares of Common
Stock  issued  upon  exercise  of this  Warrant  (unless  registered  under  the
Securities  Act),  shall be stamped or imprinted with a legend in  substantially
the  following  form (in addition to any legends  required by  applicable  state
securities laws):

          THE SECURITIES  EVIDENCED BY THIS  CERTIFICATE HAVE NOT BEEN
          REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED.  NO
          SALE OR  DISPOSITION  OF  SUCH  SECURITIES  MAY BE  EFFECTED
          WITHOUT (i) AN  EFFECTIVE  REGISTRATION  STATEMENT  RELATING
          THERETO,  OR (ii) AN  OPINION  OF  COUNSEL  FOR THE  HOLDER,
          REASONABLY   SATISFACTORY   TO  THE   COMPANY,   THAT   SUCH
          REGISTRATION IS NOT REQUIRED.

                  (c)  Disposition  of Warrant or  Shares.  With  respect to any
offer,  sale or other  disposition of this Warrant or any shares of Common Stock
issued upon exercise of this Warrant prior to registration  under the Securities
Act of such shares, the Holder or the Shareholder, as the case may be, agrees to
give  written  notice to the  Company  prior  thereto,  describing  briefly  the
circumstances  thereof,  together  with a written  opinion  of the  Holder's  or
Shareholder's  counsel, to the effect that such offer, sale or other disposition
may be effected without  registration  under the Securities Act or qualification
under any applicable  state  securities laws of this Warrant or such shares,  as
the  case may be,  and  indicating  whether  or not  under  the  Securities  Act
certificates for this Warrant or such shares,  as the case may be, to be sold or
otherwise   disposed  of  require  any  restrictive   legend  as  to  applicable
restrictions  on   transferability  in  order  to  insure  compliance  with  the
Securities  Act.  Promptly upon  receiving  such written  notice and  reasonably
satisfactory opinion, if so requested,  the Company, as promptly as practicable,
shall notify the Holder or the Shareholder, as the case may be, that it may sell
or otherwise  dispose of this Warrant or such shares, as the case may be, all in
accordance  with  the  terms  of  the  notice  delivered  to the  Company.  If a
determination  has been made pursuant to this Section 3.2(c) that the opinion of
counsel for the Holder or the Shareholder, as the case may be, is not reasonably
satisfactory  to the  Company,  the  Company  shall so notify  the Holder or the
Shareholder, as the case may be, promptly after such determination has been made
and  shall  specify  the  legal  analysis   supporting   any  such   conclusion.
Notwithstanding the foregoing,  this Warrant or such shares, as the case may be,
may be  offered,  sold or  otherwise  disposed of in  accordance  with Rule 144,
provided that the Company shall have been furnished with such information as the
Company  may  reasonable  request  to  provide  reasonable  assurance  that  the
provisions of Rule 144 have been satisfied.  Each certificate  representing this
Warrant or the shares thus transferred  (except a transfer pursuant to Rule 144)
shall bear a legend as to the  applicable  restrictions  on  transferability  in
order to insure  compliance  with the  Securities  Act,  unless in the aforesaid
reasonably satisfactory opinion of counsel for the Holder or the Shareholder, as
the case may be, such legend is not necessary in order to insure compliance with
the  Securities  Act. The Company may issue stop  transfer  instructions  to its
transfer agent in connection with such restrictions.

                  (d) Warrant Transfer Procedure.  Transfer of this Warrant to a
third party, following compliance with the preceding subsections of this Section
3.2,  shall be effected by execution of the Assignment  Form attached  hereto as
Exhibit C, and  surrender of this  Warrant at the  Principal  Executive  Office,
together with funds sufficient to pay any applicable transfer tax. Upon

                                       -4-

<PAGE>



receipt of the duly  executed  Assignment  Form and the  necessary  transfer tax
funds, if any, the Company,  at its expense,  shall execute and deliver,  in the
name of the  designated  transferee  or  transferees,  one or more new  Warrants
representing  the right to purchase a like aggregate  number of shares of Common
Stock.

                  (e)  Termination of  Restrictions.  The  restrictions  imposed
under this Section 3.2 upon the transferability of the Warrant and the shares of
Common Stock  acquired  upon the  exercise of this Warrant  shall cease (i) with
respect to the Common Shares  acquired  pursuant to the exercise of this Warrant
only,  if a  registration  statement  covering  the shares of Common Stock to be
issued effective under the Securities Act at the time of such exercise,  or (ii)
if the Company is presented with an opinion of counsel  reasonably  satisfactory
to the Company that such  restrictions are no longer required in order to insure
compliance  with  the  Securities  Act,  or  (iii)  if  such  securities  may be
transferred in accordance with Rule 144(k).  When such  restrictions  terminate,
the Company shall, or shall instruct its transfer agent to, promptly and without
expense  to the  Holder  or the  Shareholder,  as the  case  may be,  issue  new
securities in the name of the Holder and/or the Shareholder, as the case may be,
not bearing  the  legends  required  under  Section  3.2(b).  In  addition,  new
securities  shall be issued without such legends if such legends may be properly
removed under the terms of Rule 144(k).

                  (f)  Lock-Up  Provision.  The  holder of this  Warrant  hereby
represents,  warrants, and agrees that, commencing on the effective date of this
Warrant  and   continuing   until   [January  1,   1998/April  1,  1998/July  1,
1998/September  1, 1998]  (the  "Lock-Up  Period"),  the  undersigned  will not,
without the prior written consent of the Company, offer, sell, contract to sell,
pledge,  grant  any  option  to sell,  or  otherwise  dispose  of,  directly  or
indirectly,  any shares of Common Stock received or receivable  from exercise of
this  Warrant of which the holder of this  Warrant is now,  or may in the future
become, the beneficial owner (within the meaning of Rule 13d-3 of the Securities
Exchange Act of 1934, as amended).

                  Notwithstanding this lock-up provision,  if the holder of this
Warrant is an individual, he or she may transfer shares of Common Stock on death
by gift,  will, or intestacy,  to his or her immediate  family or to a trust the
beneficiaries  of which are  exclusively  a member or  members  of this  Warrant
holder's immediate family; provided,  however, that in any such case it shall be
a condition to any such transfer that any such  transferee  execute an agreement
stating that the  transferee  is receiving and holding such Common Stock subject
to the provisions of this agreement,  and there shall be no further  transfer of
such Common Stock except in accordance with this agreement.

                  With respect to this lock-up  provision,  all shares of Common
Stock issued upon exercise of this Warrant shall be stamped or imprinted  with a
legend in substantially the following form:


                                       -5-

         1998/JULY  1,   1998/SEPTEMBER  1,  1998]  SUBJECT  TO  THE  TERMS  AND
         CONDITIONS OF A WARRANT  AGREEMENT A COPY OF WHICH MAY BE OBTAINED UPON
         WRITTEN REQUEST TO THE SECRETARY OF THE CORPORATION.

                  The  holder  of this  Warrant  further  understands  that  the
disposition  of any and all shares of Common Stock issued upon  exercise of this
Warrant in  contravention  of the lock-up  provision herein shall be voidable by
the Company and that the Company will have the right to do all things  necessary
to void such transfer.

                  It is  understood  and  agreed  that upon  termination  of the
Lock-Up  Period,  the terms and conditions set forth in this  subsection  3.2(f)
shall cease.

4.       Antidilution Provisions

         4.1   Reorganization,   Reclassification  or  Recapitalization  of  the
Company.  In  case  of  (i)  a  capital   reorganization,   reclassification  or
recapitalization  of the  Company's  capital  stock  (other  than  in the  cases
referred to in of Section  4.4  hereof),  (ii) the  Company's  consolidation  or
merger  with or  into  another  corporation  in  which  the  Company  is not the
surviving  entity,  or a reverse  triangular  merger in which the Company is the
surviving  entity  but the shares of the  Company's  capital  stock  outstanding
immediately  prior to the merger are  converted,  by virtue of the merger,  into
other property,  whether in the form of securities,  cash or otherwise, or (iii)
the sale or transfer of the Company's  property as an entirety or  substantially
as  an  entirety,   then,  as  part  of  such  reorganization,   reorganization,
recapitalization,  merger,  consolidation,  sale or transfer,  lawful  provision
shall be made so that there shall thereafter be deliverable upon the exercise of
this Warrant or any portion  thereof (in lieu of or in addition to the number of
shares of Common Stock  theretofore  deliverable,  as appropriate),  and without
payment of any additional consideration,  the number of shares of stock or other
securities  or  property  to which the  holder of the number of shares of Common
Stock which would  otherwise  have been  deliverable  upon the  exercise of this
Warrant  or  any   portion   thereof   at  the  time  of  such   reorganization,
reclassification,  recapitalization,  consolidation,  merger,  sale or  transfer
would have been  entitled to receive in such  reorganization,  reclassification,
recapitalization,  consolidation,  merger,  sale or  transfer.  This Section 4.1
shall apply to successive reorganizations, reclassifications, recapitalizations,
consolidations,  mergers,  sales and transfers and to the stock or securities of
any other  corporation that are at the time receivable upon the exercise of this
Warrant.  If the  per-share  consideration  payable  to the Holder for shares of
Common Stock in connection with any transaction described in this Section 4.1 is
in a form  other  than  cash or  marketable  securities,  then the value of such
consideration  shall  be  determined  in good  faith by the  Company's  Board of
Directors.

         4.2 Splits and Combinations.  If the Company at any time subdivides any
of its outstanding  shares of Common Stock into a greater number of shares,  the
Exercise  Price  in  effect  immediately  prior  to such  subdivision  shall  be
proportionately  reduced,  and,  conversely if the outstanding  shares of Common
Stock are combined into a smaller number of shares, the Exercise Price in effect
immediately prior to such combination shall be proportionately  increased.  Upon
any

                                       -6-

<PAGE>



adjustment of the Exercise Price under this Section 4.2, the number of shares of
Common Stock  issuable  upon  exercise of this Warrant shall equal the number of
shares  determined by dividing (i) the aggregate  Exercise Price payable for the
purchase of all shares issuable upon exercise of this Warrant  immediately prior
to such  adjustment by (ii) the Exercise  Price per share in effect  immediately
after such adjustment.

         4.3 Reclassifications.  If the Company changes any of the securities as
to which  purchase  rights under this Warrant exist into the same or a different
number  of  securities  of any  other  class  or  classes,  this  Warrant  shall
thereafter  represent the right to acquire such number and kind of securities as
would  have been  issuable  as the  result of such  change  with  respect to the
securities  that  were  subject  to  the  purchase  rights  under  this  Warrant
immediately  prior to such  reclassification  or other  change and the  Exercise
Price  therefor shall be  appropriately  adjusted.  No adjustment  shall be made
pursuant  to this  Section  4.3 upon any  conversion  described  in Section  4.1
hereof.

         4.4 Liquidation;  Dissolution. If the Company shall dissolve, liquidate
or wind up its affairs, the Holder shall have the right, but not the obligation,
to  exercise  this  Warrant  effective  as of  the  date  of  such  dissolution,
liquidation  or winding up. If any such  dissolution,  liquidation or winding up
results  in any cash  distribution  to the  Holder in  excess  of the  aggregate
Exercise  Price for the  shares  of Common  Stock  for  which  this  Warrant  is
exercised,  then the Holder may, at its option,  exercise  this Warrant  without
making payment of such  aggregate  Exercise Price and, in such case, the Company
shall, upon distribution to the Holder,  consider such aggregate  Exercise Price
to have been paid in full,  and in making such  settlement to the Holder,  shall
deduct an amount equal to such aggregate  Exercise Price from the amount payable
to the Holder.

5.       Company's Forced Exercise Right

         At any time after the date this Warrant is issued to the Purchaser, and
after the Fair Market  Value of the  Company's  Common Stock is $6.00 or greater
for twenty (20) trading  days,  the Company  shall have the right to demand that
the holder of this  Warrant  exercise  this Warrant  (the  "Demand  Right").  In
exercising its Demand Right, the Company shall provide the Purchaser twenty (20)
days prior written notice (the "Demand Notice") stating that the Company intends
to exercise  its Demand  Right for a portion or all of the Warrant and all other
warrants  issued  pursuant  to  the  issuance  of  the  Company's  Common  Stock
Subscription  Offering dated as of September 30, 1997, on a pro-rata basis.  The
Demand Notice shall designate the date of exercise (the "Forced  Exercise Date")
for the Demand Right.  Upon receipt of the Demand  Notice,  the Purchaser  shall
have the right to  exercise  this  Warrant  for that  amount of Shares of Common
Stock as stated in the Demand  Notice.  To the extent  the  Purchaser  elects to
exercise this Warrant with respect to any or all shares of Common Stock that are
subject to the Demand Notice,  the Purchaser shall do so in the manner specified
in Section 2.1 herein and notwithstanding Section 2.1, the Purchaser must return
the Warrant to the Company  within five (5) days from the Forced  Exercise Date.
As soon as  practicable  upon  receipt of the Warrant  (but in no case more than
five (5) days thereafter),  the Company will send a new Warrant,  if applicable,
of like tenor for the number of shares of Common Stock remaining,  if any, after
exercise by the Company of the Demand Right or exercise by the  Purchaser of the
Warrant.  After the Forced  Exercise Date, the portion of the Warrant subject to
the Demand Right and not exercised by the Purchaser as described in this Section
5 shall be deemed terminated on the Forced Exercise Date.

         6.6      Severability.

                  (a) If, in any  action  before  any  court or  agency  legally
empowered to enforce any term, any term is found to be unenforceable,  then such
term shall be deemed modified to the extent  necessary to make it enforceable by
such court or agency.

                  (b) If any term is not curable as set forth in subsection  (a)
above, the  unenforceability  of such term shall not affect the other provisions
of this  Warrant but this Warrant  shall be  construed as if such  unenforceable
term had never been contained herein.

certain Series B Preferred  Stock  Subscription  Agreement among the Company and
the  Holder  hereof,  entered  into  of  even  date  herein  (the  "Subscription
Agreement").  The  Subscription  Agreement and the other documents  entered into
pursuant thereto,  including,  without limitation,  this Warrant, constitute the
full and entire  understanding  and  agreement  between the  parties  hereto and
thereto with regard to the subject matter hereof and thereof,  and supersede any
prior or contemporaneous  understandings,  agreements or representations between
them that relate to the subject matter hereof or thereof.

         6.8 Waiver and Amendment. Any provision of this Warrant may be amended,
waived, modified or verified, including by way of settlements or otherwise, upon
the   written   consent  of  the   Company   and  the  holders  of  at  least  a

Subscription Agreement with the same terms hereof.

accordance  with,  the laws of the State of  California  applicable to contracts
entered  into  and  to be  performed  wholly  within  California  by  California

                      Investment Representation Certificate


Purchaser:      ________________________________________________________________

Company:        Telegen Corporation, a California corporation

Security:       Common Stock

Amount:         ________________________________________________________________

Date:           ________________________________________________________________
 

         In connection  with the purchase of the  above-listed  securities  (the
"Securities"),  the undersigned (the  "Purchaser")  represents to the Company as
follows:

         (a) The  Purchaser  is  aware of the  Company's  business  affairs  and
financial condition,  and has acquired sufficient  information about the Company
to reach an informed and knowledgeable  decision to acquire the Securities.  The
Purchaser  is  purchasing  the  Securities  for its own account  for  investment
purposes only and not with a view to, or for the resale in connection  with, any
"distribution"  thereof for purposes of the  Securities  Act of 1933, as amended
(the "Securities Act");

         (b) The Purchaser  understands  that the  Securities  may have not been
registered  under the  Securities  Act in  reliance  upon a  specific  exemption
therefor, which exemption depends upon, among other things, the bona fide nature
of the Purchaser's  investment  intent as expressed  herein. In this connection,
the  Purchaser  understands  that,  in the view of the  Securities  and Exchange
Commission  (the  "Commission"),  the statutory  basis for such exemption may be
unavailable  if the  Purchaser's  representation  was  predicated  solely upon a
present  intention to hold these Securities for the minimum capital gains period
specified  under tax statutes,  for a deferred sale, for or until an increase or
decrease in the market price of the  Securities,  or for a period of one year or
any other fixed period in the future;

         (c) The Purchaser further  understands that the Securities must be held
indefinitely unless  subsequently  registered under the Securities Act or unless
an  exemption  from  registration  is  otherwise  available.  In  addition,  the
Purchaser  understands  that the  certificate  evidencing the Securities will be
imprinted with the legend  referred to in the Warrant under which the Securities
are being purchased unless there exists an effective  registration statement for
such securities;

         (d) The Purchaser is aware of the  provisions of Rule 144,  promulgated
under the Securities Act,  which, in substance,  permit limited public resale of
"restricted  securities"  acquired,  directly  or  indirectly,  from the  issuer
thereof (or from an affiliate of such issuer),  in a non-public offering subject
to the satisfaction of certain conditions, if applicable, including, among other
things:  (i) the availability of certain public  information  about the Company;
(ii) the  resale  occurring  not less  than one (1) year  after  the  party  has
purchased  and paid for the  securities  to be sold;  (iii) the sale  being made
through a broker in an unsolicited  "broker's  transaction"  or in  transactions
directly  with a market  maker (as said  term is  defined  under the  Securities
Exchange Act of 1934) and the amount


<PAGE>



of  securities  being sold  during any  three-month  period  not  exceeding  the
specified limitations stated therein;

         (e) The  Purchaser  further  understands  that at the time it wishes to
sell the  Securities  there may be no public  market  upon  which to make such a
sale, and that, even if such a public market upon which to make such a sale then
exists,  the  Company  may not be  satisfying  the  current  public  information
requirements  of Rule  144,  and  that,  in such  event,  the  Purchaser  may be
precluded  from  selling  the  Securities  under  Rule 144 even if the  one-year
minimum holding period had been satisfied; and

         (f) The  Purchaser  further  understands  that in the  event all of the
requirements  of Rule 144 are not satisfied,  registration  under the Securities
Act, compliance with Regulation A, or some other registration  exemption will be
required; and that, notwithstanding the fact that Rule 144 is not exclusive, the
staff of the Commission has expressed its opinion that persons proposing to sell
private placement  securities other than in a registered  offering and otherwise
than  pursuant  to  Rule  144  will  have  a  substantial  burden  of  proof  in
establishing that an exemption from registration is available for such offers or
sales,  and that such persons and their  respective  brokers who  participate in
such transactions do so at their own risk.
