INFORMATION REQUIRED IN THE REGISTRATION STATEMENT


ITEM 3. INCORPORATION OF DOCUMENTS BY REFERENCE
        ---------------------------------------


    There are hereby incorporated by reference into this Registration Statement
the following documents and information heretofore filed by Telegen Corporation
(the "Company") with the Securities and Exchange Commission:

    1.  The Company's Quarterly Report on Form 10-QSB for the fiscal quarter
        ended September 30, 1996 filed on November 12, 1996.

    2.  The Information Statement and Prospectus of Solar Energy Research Corp.,
        a Colorado corporation ("SERC," subsequently redomiciled in California
        and renamed "Telegen Corporation") included in SERC's Registration
        Statement on Form S-4 (Reg No. 333-4037) filed on May 17, 1996, as
        amended (the "Form S-4").

        filed pursuant to Section 12 of the Exchange Act on May 12, 1993,
        including any amendment or report filed for the purpose of updating such

        All documents filed by the Company pursuant to Sections 13(a), 13(c), 14
and 15(d) of the Securities Exchange Act of 1934, on or after the date of this
Registration Statement and prior to the filing of a post-effective amendment

ITEM 4. DESCRIPTION OF SECURITIES
        -------------------------

        Not Applicable.


ITEM 5. INTERESTS OF NAMED EXPERTS AND COUNSEL
        --------------------------------------

        Counsel for the Company, Wilson, Sonsini, Goodrich & Rosati,
Professional Corporation, 650 Page Mill Road, Palo Alto, California 94304-1050,
has rendered an opinion to the effect that the Common Stock offered hereby will,
when issued in accordance with the registrant's Employee Stock Option
Agreements, 1996 Director Stock Option Plan, 1996 Stock Plan and 1996 Employee
Stock Purchase Plan, be legally and validly issued, fully paid and non-
assessable.  As of the date of this Registration Statement, a member of Wilson,
Sonsini, Goodrich & Rosati, Professional Corporation, and investment
partnerships of which members of such firm are partners beneficially own 10,000
shares of the Company's Common Stock.


ITEM 6. INDEMNIFICATION OF DIRECTORS AND OFFICERS
        -----------------------------------------

        The Bylaws of the Company provide for indemnification of agents of the
Company, including officers and directors, who were or are parties or are
threatened to be made parties to any action or proceeding against expenses,
judgments, fines, settlements and other amounts actually and reasonably incurred
in connection with all threatened, pending or completed actions or proceedings,
including civil, criminal, administrative, arbitration and investigative actions
and proceedings, including any appeal thereof, that arise by reason of the fact
that any such persons are or were agents of the Company.  Section 317 of the
California Corporations Code authorizes a court to award, or a Company'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
of 1933, as amended (the "Securities Act").  The Company's Amended Articles of
Incorporation provide for indemnification of directors to the maximum extent
permitted by California law.  Pursuant to the authority provided in its Amended
Articles of Incorporation, the Company has entered into indemnification
agreements with each of its officers and directors, indemnifying them against
certain potential liabilities that may arise as a result of their service of the
Company, and providing for certain other protections.

    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 foregoing provisions, 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 7. EXEMPTION FROM REGISTRATION CLAIMED
        -----------------------------------

ITEM 9.     UNDERTAKINGS
            ------------

    (a)  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 (the "Securities Act");

             (ii)  To reflect in the prospectus any facts or events arising
         after the effective date of the Registration Statement (or the most
         recent post-effective amendment thereof) which, individually or in the
         aggregate, represent a fundamental change in the information set forth
         in the Registration Statement;

             (iii) 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.

                                      II-3
<PAGE>
 
         (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.
 
    (b)  The undersigned registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act, 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.

    (c)  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 California General Corporation Law, the Amended
Articles of Incorporation and the Bylaws of the Company, Indemnification
Agreements entered into between the Registration and its officers and directors,
or otherwise, the Registrant has been advised that in the opinion of the
Securities and Exchange Commission such indemnification is against public policy
as expressed in the 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 hereunder, 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.

Company.  The Exercise Notice shall be accompanied by payment of the aggregate
Exercise Price as to all Exercised Shares.  This Option shall be deemed to be
exercised upon receipt by the Company of such fully executed Exercise Notice
accompanied by such aggregate Exercise Price.

          No Shares shall be issued pursuant to the exercise of this Option
unless such issuance and exercise complies with Applicable Laws.  Assuming such
compliance, for income tax purposes the Exercised Shares shall be considered
transferred to the Optionee on the date the Option is exercised with respect to
such Exercised Shares.

3.   Method of Payment.  Payment of the aggregate Exercise Price shall be by any
     -----------------

stock option ("NSO").  The Optionee may incur regular federal income tax
liability upon exercise of a NSO.  The Optionee will be treated as having
received compensation income (taxable at ordinary income tax rates) equal to the
excess, if any, of the Fair Market Value of the Exercised Shares on the date of
exercise over their aggregate Exercise Price.  If the Optionee is an Employee or
a former Employee, the Company will be required to withhold from his or her
compensation or collect from Optionee and pay to the applicable taxing
authorities an amount in cash equal to a percentage of this compensation income
at the time of exercise, and may refuse to honor the exercise and refuse to
deliver Shares if such withholding amounts are not delivered at the time of
exercise.

     (b)  Disposition of Shares.   If the Optionee holds NSO Shares for at least
          ---------------------

     -------------------------------

supersedes in its entirety all prior undertakings and agreements of the Company
and Optionee with respect to the subject matter hereof, and may not be modified
adversely to the Optionee's interest except by means of a writing signed by the
Company and Optionee.  This agreement is governed by the internal substantive
laws, but not the choice of law rules, of California.

8.   NO GUARANTEE OF CONTINUED SERVICE.  OPTIONEE ACKNOWLEDGES AND AGREES THAT

TERMINATE OPTIONEE'S RELATIONSHIP AS A SERVICE PROVIDER AT ANY TIME, WITH OR
WITHOUT CAUSE.

DISPOSING OF THE SHARES.

     (a) Exercising the Option.  This option will be treated as a nonstatutory
         ---------------------                                                
stock option ("NSO"). The Optionee may incur regular federal income tax
liability upon exercise of a NSO. The Optionee will be treated as having
received compensation income (taxable at ordinary income tax rates) equal to the
excess, if any, of the Fair Market Value of the Exercised Shares on the date of
exercise over their aggregate Exercise Price. If the Optionee is an Employee or
a former Employee, the Company will be required to withhold from his or her
compensation or collect from Optionee and pay to the applicable taxing
authorities an amount in cash equal to a percentage of this compensation income
at the time of exercise, and may refuse to honor the exercise and refuse to
deliver Shares if such withholding amounts are not delivered at the time of
exercise.

     (b) Disposition of Shares.   If the Optionee holds NSO Shares for at least
         ---------------------                                                
one year, any gain realized on disposition of the Shares will be treated as
long-term capital gain for federal income tax purposes.

supersedes in its entirety all prior undertakings and agreements of the Company
and Optionee with respect to the subject matter hereof, and may not be modified
adversely to the Optionee's interest except by means of a writing signed by the
Company and Optionee. This agreement is governed by the internal substantive
laws, but not the choice of law rules, of California.

8.   NO GUARANTEE OF CONTINUED SERVICE.  OPTIONEE ACKNOWLEDGES AND AGREES THAT

provisions of the Plan, accordingly, shall be construed so as to extend and
limit participation in a manner consistent with the requirements of that section
of the Code.

         (b) Any provisions of the Plan to the contrary notwithstanding, no

would be attributed to such Employee pursuant to Section 424(d) of the Code)

purchase such stock possessing five percent (5%) or more of the total combined

stock (determined at the fair market value of the shares at the time such option

     4.  Offering Periods.  The Plan shall be implemented by consecutive,
          ----------------

the Board shall determine, and continuing thereafter until terminated in
accordance with Section 19 hereof. The first Offering Period shall be the period
commencing with the first Trading Day on or after the date on which the
Company's stock is actively traded on either the Nasdaq National Market system
or the Nasdaq SmallCap Market system and terminating on the last Trading Day on
or before November 1, 1998. The Board shall have the power to change the

respect to future offerings without shareholder approval if such change is

Offering Period to be affected thereafter.

     5.  Participation.
         ------------- 

         (a) An eligible Employee may become a participant in the Plan by
completing a subscription agreement authorizing payroll deductions in the form
of Exhibit A to this Plan and filing it with the Company's payroll office prior
to the applicable Enrollment Date.

         (b) Payroll deductions for a participant shall commence on the first
payroll following the Enrollment Date and shall end on the last payroll in the
Offering Period to which such authorization is applicable, unless sooner
terminated by the participant as provided in Section 10 hereof.

     6.  Payroll Deductions.
         ------------------ 

         (a) At the time a participant files his or her subscription agreement,
he or she shall elect to have payroll deductions made on each pay day during the
Offering Period in an amount not exceeding fifteen (15%) of the Compensation
which he or she receives on each pay day during the Offering Period.


                                      -3-
<PAGE>
 
         (b) All payroll deductions made for a participant shall be credited to
his or her account under the Plan and shall be withheld in whole percentages
only.  A participant may not make any additional payments into such account.

         (c) A participant may discontinue his or her participation in the Plan
as provided in Section 10 hereof, or may increase or decrease the rate of his or
her payroll deductions during the Offering Period by completing or filing with
the Company a new subscription agreement authorizing a change in payroll
deduction rate. The Board may, in its discretion, limit the number of
participation rate changes during any Offering Period. The change in rate shall
be effective with the first full payroll period following five (5) business days
after the Company's receipt of the new subscription agreement unless the Company
elects to process a given change in participation more quickly. A participant's
subscription agreement shall remain in effect for successive Offering Periods
unless terminated as provided in Section 10 hereof.

         (d) Notwithstanding the foregoing, to the extent necessary to comply
with Section 423(b)(8) of the Code and Section 3(b) hereof, a participant's
payroll deductions may be decreased to zero percent (0%) at such time during any
Purchase Period which is scheduled to end during the current calendar year (the
"Current Purchase Period") that the aggregate of all payroll deductions which
were previously used to purchase stock under the Plan in a prior Purchase Period
which ended during that calendar year plus all payroll deductions accumulated
with respect to the Current Purchase Period equal $21,250. Payroll deductions
shall recommence at the rate provided in such participant's subscription
agreement at the beginning of the first Purchase Period which is scheduled to
end in the following calendar year, unless terminated by the participant as
provided in Section 10 hereof.

         (e) At the time the option is exercised, in whole or in part, or at the
time some or all of the Company's Common Stock issued under the Plan is disposed
of, the participant must make adequate provision for the Company's federal,
state, or other tax withholding obligations, if any, which arise upon the
exercise of the option or the disposition of the Common Stock. At any time, the
Company may, but shall not be obligated to, withhold from the participant's
compensation the amount necessary for the Company to meet applicable withholding
obligations, including any withholding required to make available to the Company
any tax deductions or benefits attributable to sale or early disposition of
Common Stock by the Employee.

     7.  Grant of Option.  On the Enrollment Date of each Offering Period, each
         ---------------                                                       
eligible Employee participating in such Offering Period shall be granted an
option to purchase on each Exercise Date during such Offering Period (at the
applicable Purchase Price) up to a number of shares of the Company's Common
Stock determined by dividing such Employee's payroll deductions accumulated
prior to such Exercise Date and retained in the Participant's account as of the
Exercise Date by the applicable Purchase Price; provided that in no event shall
an Employee be permitted to purchase during each Purchase Period more than a
number of shares determined by dividing $12,500 by the Fair Market Value of a
share of the Company's Common Stock on the Enrollment Date, and provided further
that such purchase shall be subject to the limitations set forth in Sections
3(b) and 12 hereof. Exercise of the option shall occur as provided in Section 8
hereof, unless the participant has

                                      -4-
<PAGE>
 
withdrawn pursuant to Section 10 hereof. The option shall expire on the last day
of the Offering Period.

     8.  Exercise of Option.  Unless a participant withdraws from the Plan as
         ------------------                                                  
provided in Section 10 hereof, his or her option for the purchase of shares
shall be exercised automatically on the Exercise Date, and the maximum number of
full shares subject to option shall be purchased for such participant at the
applicable Purchase Price with the accumulated payroll deductions in his or her
account. No fractional shares shall be purchased; any payroll deductions
accumulated in a participant's account which are not sufficient to purchase a
full share shall be retained in the participant's account for the subsequent
Purchase Period or Offering Period, subject to earlier withdrawal by the
participant as provided in Section 10 hereof. Any other monies left over in a
participant's account after the Exercise Date shall be returned to the
participant. During a participant's lifetime, a participant's option to purchase
shares hereunder is exercisable only by him or her.

     9.  Delivery.  As promptly as practicable after each Exercise Date on
         --------                                                         
which a purchase of shares occurs, the Company shall arrange the delivery to
each participant, as appropriate, of a certificate representing the shares
purchased upon exercise of his or her option.

     10.  Withdrawal; Termination of Employment.
          ------------------------------------- 

         (a) A participant may withdraw all but not less than all the payroll
deductions credited to his or her account and not yet used to exercise his or
her option under the Plan at any time by giving written notice to the Company in
the form of Exhibit B to this Plan. All of the participant's payroll deductions
credited to his or her account shall be paid to such participant promptly after
receipt of notice of withdrawal and such participant's option for the Offering
Period shall be automatically terminated, and no further payroll deductions for
the purchase of shares shall be made for such Offering Period. If a participant
withdraws from an Offering Period, payroll deductions shall not resume at the
beginning of the succeeding Offering Period unless the participant delivers to
the Company a new subscription agreement.

         (b) Upon a participant's ceasing to be an Employee (as defined in
Section 2(g) hereof), for any reason, he or she shall be deemed to have elected
to withdraw from the Plan and the payroll deductions credited to such
participant's account during the Offering Period but not yet used to exercise
the option shall be returned to such participant or, in the case of his or her
death, to the person or persons entitled thereto under Section 14 hereof, and
such participant's option shall be automatically terminated. The preceding
sentence notwithstanding, a participant who receives payment in lieu of notice
of termination of employment shall be treated as continuing to be an Employee
for the participant's customary number of hours per week of employment during
the period in which the participant is subject to such payment in lieu of
notice.

         (c) A participant's withdrawal from an Offering Period shall not have
any effect upon his or her eligibility to participate in any similar plan which
may hereafter be adopted by the


                                      -5-
<PAGE>
 
Company or in succeeding Offering Periods which commence after the termination
of the Offering Period from which the participant withdraws.


     11. Interest. No interest shall accrue on the payroll deductions of a
         --------
participant in the Plan.

     12. Stock.
         ----- 

         (a) The maximum number of shares of the Company's Common Stock which
shall be made available for sale under the Plan shall be two hundred thousand
(200,000) shares, subject to adjustment upon changes in capitalization of the
Company as provided in Section 18 hereof. If, on a given Exercise Date, the
number of shares with respect to which options are to be exercised exceeds the
number of shares then available under the Plan, the Company shall make a pro
rata allocation of the shares remaining available for purchase in as uniform a
manner as shall be practicable and as it shall determine to be equitable.

         (b) The participant shall have no interest or voting right in shares
covered by his option until such option has been exercised.

         (c) Shares to be delivered to a participant under the Plan shall be
registered in the name of the participant or in the name of the participant and
his or her spouse.

     13. Administration.
         -------------- 

         (a) Administrative Body.  The Plan shall be administered by the Board
             -------------------                                              
or a committee of members of the Board appointed by the Board. The Board or its
committee shall have full and exclusive discretionary authority to construe,
interpret and apply the terms of the Plan, to determine eligibility and to
adjudicate all disputed claims filed under the Plan. Every finding, decision and
determination made by the Board or its committee shall, to the full extent
permitted by law, be final and binding upon all parties.

         (b) Rule 16b-3 Limitations.  Notwithstanding the provisions of
             ----------------------                                    
Subsection (a) of this Section 13, in the event that Rule 16b-3 promulgated
under the Securities Exchange Act of 1934, as amended (the "Exchange Act"), or
any successor provision ("Rule 16b-3") provides specific requirements for the
administrators of plans of this type, the Plan shall be administered only by
such a body and in such a manner as shall comply with the applicable
requirements of Rule 16b-3. Unless permitted by Rule 16b-3, no discretion
concerning decisions regarding the Plan shall be afforded to any committee or
person that is not "disinterested" as that term is used in Rule 16b-3.

     14. Designation of Beneficiary.
         -------------------------- 

         (a) A participant may file a written designation of a beneficiary who
is to receive any shares and cash, if any, from the participant's account under
the Plan in the event of such participant's death subsequent to an Exercise Date
on which the option is exercised but prior to delivery to such participant of
such shares and cash. In addition, a participant may file a written

                                      -6-
<PAGE>
 
designation of a beneficiary who is to receive any cash from the participant's
account under the Plan in the event of such participant's death prior to
exercise of the option. If a participant is married and the designated
beneficiary is not the spouse, spousal consent shall be required for such
designation to be effective.

         (b) Such designation of beneficiary may be changed by the participant
at any time by written notice. In the event of the death of a participant and in
the absence of a beneficiary validly designated under the Plan who is living at
the time of such participant's death, the Company shall deliver such shares
and/or cash to the executor or administrator of the estate of the participant,
or if no such executor or administrator has been appointed (to the knowledge of
the Company), the Company, in its discretion, may deliver such shares and/or
cash to the spouse or to any one or more dependents or relatives of the
participant, or if no spouse, dependent or relative is known to the Company,
then to such other person as the Company may designate.

     15.  Transferability.  Neither payroll deductions credited to a
          ---------------                                           
participant's account nor any rights with regard to the exercise of an option or
to receive shares under the Plan may be assigned, transferred, pledged or
otherwise disposed of in any way (other than by will, the laws of descent and
distribution or as provided in Section 14 hereof) by the participant. Any such
attempt at assignment, transfer, pledge or other disposition shall be without
effect, except that the Company may treat such act as an election to withdraw
funds from an Offering Period in accordance with Section 10 hereof.

     16.  Use of Funds.  All payroll deductions received or held by the Company
          ------------                                                         
under the Plan may be used by the Company for any corporate purpose, and the
Company shall not be obligated to segregate such payroll deductions.

     17.  Reports.  Individual accounts shall be maintained for each participant
          -------                                                               
in the Plan. Statements of account shall be given to participating Employees at
least annually, which statements shall set forth the amounts of payroll
deductions, the Purchase Price, the number of shares purchased and the remaining
cash balance, if any.

     18.  Adjustments Upon Changes in Capitalization, Dissolution, Liquidation,
          ---------------------------------------------------------------------
          Merger or Asset Sale.
          -------------------- 

          (a) Changes in Capitalization.  Subject to any required action by the
              -------------------------                                        
shareholders of the Company, the Reserves, as well as the price per share and
the number of shares of Common Stock covered by each option under the Plan which
has not yet been exercised, shall be proportionately adjusted for any increase
or decrease in the number of issued shares of Common Stock resulting from a
stock split, reverse stock split, stock dividend, combination or
reclassification of the Common Stock, or any other increase or decrease in the
number of shares of Common Stock effected without receipt of consideration by
the Company; provided, however, that conversion of any convertible securities of
the Company shall not be deemed to have been "effected without receipt of
consideration". Such adjustment shall be made by the Board, whose determination
in that respect shall be final, binding and conclusive. Except as expressly
provided herein, no issuance by the Company of shares of stock of any class, or
securities convertible into shares of stock of any class,

                                      -7-
<PAGE>
 
shall affect, and no adjustment by reason thereof shall be made with respect to,
the number or price of shares of Common Stock subject to an option.

          (b) Dissolution or Liquidation. In the event of the proposed
              --------------------------
dissolution or liquidation of the Company, the Offering Periods shall terminate
immediately prior to the consummation of such proposed action, unless otherwise
provided by the Board.

          (c) Merger or Asset Sale.  In the event of a proposed sale of all or
              --------------------                                            
substantially all of the assets of the Company, or the merger of the Company
with or into another corporation, any Purchase Periods then in progress shall be
shortened by setting a new Exercise Date (the "New Exercise Date") and any
Offering Periods then in progress shall end on the New Exercise Date. The New
Exercise Date shall be before the date of the Company's proposed sale or merger.
The Board shall notify each participant in writing, at least ten (10) business
days prior to the New Exercise Date, that the Exercise Date for the
participant's option has been changed to the New Exercise Date and that the
participant's option shall be exercised automatically on the New Exercise Date,
unless prior to such date the participant has withdrawn from the Offering Period
as provided in Section 10 hereof.

     19.  Amendment or Termination.
          ------------------------ 

          (a) The Board of Directors of the Company may at any time and for any
reason terminate or amend the Plan. Except as provided in Section 18 hereof, no
such termination can affect options previously granted, provided that an
Offering Period may be terminated by the Board of Directors on any Exercise Date
if the Board determines that the termination of the Plan is in the best
interests of the Company and its shareholders. Except as provided in Section 18
hereof, no amendment may make any change in any option theretofore granted which
adversely affects the rights of any participant. To the extent necessary to
comply with Rule 16b-3 or under Section 423 of the Code (or any successor rule
or provision or any other applicable law or regulation), the Company shall
obtain shareholder approval in such a manner and to such a degree as required.

          (b) Without shareholder consent and without regard to whether any
participant rights may be considered to have been "adversely affected," the
Board (or its committee) shall be entitled to change the Offering Periods, limit
the frequency and/or number of changes in the amount withheld during an Offering
Period, establish the exchange ratio applicable to amounts withheld in a
currency other than U.S. dollars, permit payroll withholding in excess of the
amount designated by a participant in order to adjust for delays or mistakes in
the Company's processing of properly completed withholding elections, establish
reasonable waiting and adjustment periods and/or accounting and crediting
procedures to ensure that amounts applied toward the purchase of Common Stock
for each participant properly correspond with amounts withheld from the
participant's Compensation, and establish such other limitations or procedures
as the Board (or its committee) determines in its sole discretion advisable
which are consistent with the Plan.

     20.  Notices.  All notices or other communications by a participant to the
          -------

<PAGE>
 
specified by the Company at the location, or by the person, designated by the
Company for the receipt thereof.

     21.  Conditions Upon Issuance of Shares.  Shares shall not be issued with
          ----------------------------------                                  
respect to an option unless the exercise of such option and the issuance and
delivery of such shares pursuant thereto shall comply with all applicable
provisions of law, domestic or foreign, including, without limitation, the
Securities Act of 1933, as amended, the Securities Exchange Act of 1934, as
amended, the rules and regulations promulgated thereunder, and the requirements
of any stock exchange upon which the shares may then be listed, and shall be
further subject to the approval of counsel for the Company with respect to such
compliance.

          As a condition to the exercise of an option, the Company may require
the person exercising such option to represent and warrant at the time of any
such exercise that the shares are being purchased only for investment and
without any present intention to sell or distribute such shares if, in the
opinion of counsel for the Company, such a representation is required by any of
the aforementioned applicable provisions of law.

     22.  Term of Plan.  The Plan shall become effective upon the earlier to
          ------------                                                      
occur of its adoption by the Board of Directors or its approval by the
shareholders of the Company. It shall continue in effect for a term of ten (10)
years unless sooner terminated under Section 19 hereof.

     23.  Automatic Transfer to Low Price Offering Period.  To the extent
          -----------------------------------------------                
permitted by Rule 16b-3 of the Exchange Act, if the Fair Market Value of the
Common Stock on any Exercise Date in an Offering Period is lower than the Fair
Market Value of the Common Stock on the Enrollment Date of such Offering Period,
then all participants in such Offering Period shall be automatically withdrawn
from such Offering Period immediately after the exercise of their option on such
Exercise Date and automatically re-enrolled in the immediately following
Offering Period as of the first day thereof.

                            SUBSCRIPTION AGREEMENT



_____ Original Application                      Enrollment Date: ___________
_____ Change in Payroll Deduction Rate
_____ Change of Beneficiary(ies)


1.   _____________________________________________________ hereby elects to
     participate in the Telegen Corporation 1996 Employee Stock Purchase Plan
     (the "Employee Stock Purchase Plan") and subscribes to purchase shares of
     the Company's Common Stock in accordance with this Subscription Agreement
     and the Employee Stock Purchase Plan.

2.   I hereby authorize payroll deductions from each paycheck in the amount of
     ____% of my Compensation on each payday (from 1 to 15%) during the Offering
     Period in accordance with the Employee Stock Purchase Plan. (Please note
     that no fractional percentages are permitted.)

3.   I understand that said payroll deductions shall be accumulated for the
     purchase of shares of Common Stock at the applicable Purchase Price
     determined in accordance with the Employee Stock Purchase Plan. I
     understand that if I do not withdraw from an Offering Period, any
     accumulated payroll deductions will be used to automatically exercise my
     option.

4.   I have received a copy of the complete Employee Stock Purchase Plan. I
     understand that my participation in the Employee Stock Purchase Plan is in
     all respects subject to the terms of the Plan. I understand that my ability
     to exercise the option under this Subscription Agreement is subject to
     shareholder approval of the Employee Stock Purchase Plan.

5.   Shares purchased for me under the Employee Stock Purchase Plan should be
     issued in the name(s) of (Employee or Employee and Spouse only):
     ___________________________________________________________________________
     ____________.

6.   I understand that if I dispose of any shares received by me pursuant to the
     Plan within 2 years after the Enrollment Date (the first day of the
     Offering Period during which I purchased such shares) or one year after the
     Exercise Date, I will be treated for federal income tax purposes as having
     received ordinary income at the time of such disposition in an amount equal
     to the excess of the fair market value of the shares at the time such
     shares were purchased by me over the price which I paid for the shares. I
                                                                             -
     hereby agree to notify the Company in writing
     ---------------------------------------------
<PAGE>
 
     within 30 days after the date of any disposition of my shares and I will
     ------------------------------------------------------------------------
     make adequate provision for Federal, state or other tax withholding
     -------------------------------------------------------------------
     obligations, if any, which arise upon the disposition of the Common Stock.
     --------------------------------------------------------------------------
     The Company may, but will not be obligated to, withhold from my
     compensation the amount necessary to meet any applicable withholding
     obligation including any withholding necessary to make available to the
     Company any tax deductions or benefits attributable to sale or early
     disposition of Common Stock by me. If I dispose of such shares at any time
     after the expiration of the 2-year and 1-year holding periods, I understand
     that I will be treated for federal income tax purposes as having received
     income only at the time of such disposition, and that such income will be
     taxed as ordinary income only to the extent of an amount equal to the
     lesser of (1) the excess of the fair market value of the shares at the time
     of such disposition over the purchase price which I paid for the shares, or
     (2) 15% of the fair market value of the shares on the first day of the
     Offering Period. The remainder of the gain, if any, recognized on such
     disposition will be taxed as capital gain.

7.   I hereby agree to be bound by the terms of the Employee Stock Purchase
     Plan. The effectiveness of this Subscription Agreement is dependent upon my
     eligibility to participate in the Employee Stock Purchase Plan.

8.   In the event of my death, I hereby designate the following as my
     beneficiary(ies) to receive all payments and shares due me under the
     Employee Stock Purchase Plan:

               ----                                       

          (p) "Share" means a share of the Common Stock, as adjusted in
               -----

hereafter existing, as defined in Section 424(f) of the Internal Revenue Code of

     3.   Stock Subject to the Plan.  Subject to the provisions of Section 10
          -------------------------
of the Plan, the maximum aggregate number of Shares which may be optioned and
sold under the Plan is three hundred thousand (300,000) Shares of Common Stock
(the "Pool"). The Shares may be authorized, but unissued, or reacquired Common
Stock.

          If an Option expires or becomes unexercisable without having been
exercised in full, the unpurchased Shares which were subject thereto shall
become available for future grant or sale under the Plan (unless the Plan has
terminated). Shares that have actually been issued under the Plan shall not be
returned to the Plan and shall not become available for future distribution
under the Plan.

     4.   Administration and Grants of Options under the Plan.
          --------------------------------------------------- 

          (a) Procedure for Grants. All grants of Options to Outside Directors
              --------------------
under this Plan shall be automatic and nondiscretionary and shall be made
strictly in accordance with the following provisions:

              (i)  No person shall have any discretion to select which Outside
Directors shall be granted Options or to determine the number of Shares to be
covered by Options granted to Outside Directors.

                                      -2-
<PAGE>
 
              (ii)   Each Outside Director shall be automatically granted an
Option to purchase twenty thousand (20,000) Shares on each date such Outside
Director is re-elected by the shareholders. Notwithstanding the prior
sentence, an Option grant to any Outside Director will be limited to once in
any given calendar year.

              (iv)   Notwithstanding the provisions of subsections (ii) and
(iii) hereof, any exercise of an Option granted before the Company has
obtained shareholder approval of the Plan in accordance with Section 16 hereof
shall be conditioned upon obtaining such shareholder approval of the Plan in
accordance with Section 16 hereof.

              (iv)   The terms of an Option granted hereunder shall be as
follows:

                     (A) the term of the Option shall be ten (10) years.

                     (B) the Option shall be exercisable only while the
Outside Director remains a Director of the Company, except as set forth in
Sections 8 and 10 hereof.

                     (C) the exercise price per Share shall be 100% of the
Fair Market Value per Share on the date of grant of the Option. In the event
that the date of grant of the Option is not a trading day, the exercise price
per Share shall be the Fair Market Value on the next trading day immediately
following the date of grant of the Option.

                     (D) subject to Section 10 hereof, the Option shall become
exercisable as to one-twelfth (1/12) of the Shares subject to the Option on
the anniversary day of each month of the twelve (12) month period following
the date of the Option grant, provided that the Optionee continues to serve as
a Director on such dates.

              (v)    In the event that any Option granted under the Plan would
cause the number of Shares subject to outstanding Options plus the number of
Shares previously purchased under Options to exceed the Pool, then the
remaining Shares available for Option grant shall be granted under Options to
the Outside Directors on a pro rata basis. No further grants shall be made
until such time, if any, as additional Shares become available for grant under
the Plan through action of the Board or the shareholders to increase the
number of Shares which may be issued under the Plan or through cancellation or
expiration of Options previously granted hereunder.

     5.  Eligibility.  Options may be granted only to Outside Directors.  All
         -----------                                                         
Options shall be automatically granted in accordance with the terms set forth in
Section 4 hereof.

         The Plan shall not confer upon any Optionee any right with respect to
continuation of service as a Director or nomination to serve as a Director,
nor shall it interfere in any way with any rights which the Director or the
Company may have to terminate the Director's relationship with the Company at
any time.

                                      -3-

     6.  Term of Plan.  The Plan shall become effective upon the earlier to
         ------------
occur of its adoption by the Board or its approval by the shareholders of the
Company as described in Section 16 of the Plan. It shall continue in effect
for a term of ten (10) years unless sooner terminated under Section 11 of the
Plan.

     7.  Form of Consideration.  The consideration to be paid for the Shares
         ---------------------
to be issued upon exercise of an Option, including the method of payment,
shall consist of (i) cash, (ii) check, (iii) other shares which (x) in the
case of Shares acquired upon exercise of an Option, have been owned by the
Optionee for more than six (6) months on the date of surrender, and (y) have a
Fair Market Value on the date of surrender equal to the aggregate exercise
price of the Shares as to which said Option shall be exercised, (iv) delivery
of a properly executed exercise notice together with such other documentation
as the Company and the broker, if applicable, shall require to effect an
exercise of the Option and delivery to the Company of the sale or loan
proceeds required to pay the exercise price, or (v) any combination of the
foregoing methods of payment.

     8.  Exercise of Option.
         ------------------ 

         (a) Procedure for Exercise; Rights as a Shareholder.  Any Option
             -----------------------------------------------
granted hereunder shall be exercisable at such times as are set forth in
Section 4 hereof, provided, however, that no Options shall be exercisable
until shareholder approval of the Plan in accordance with Section 16 hereof
has been obtained.

         An Option may not be exercised for a fraction of a Share.

         An Option shall be deemed to be exercised when written notice of such
exercise has been given to the Company in accordance with the terms of the
Option by the person entitled to exercise the Option and full payment for the
Shares with respect to which the Option is exercised has been received by the
Company.  Full payment may consist of any consideration and method of payment
allowable under Section 7 of the Plan.  Until the issuance (as evidenced by the
appropriate entry on the books of the Company or of a duly authorized transfer
agent of the Company) of the stock certificate evidencing such Shares, no right
to vote or receive dividends or any other rights as a shareholder shall exist
with respect to the Optioned Stock, notwithstanding the exercise of the Option.
A share certificate for the number of Shares so acquired shall be issued to the
Optionee as soon as practicable after exercise of the Option.  No adjustment
shall be made for a dividend or other right for which the record date is prior
to the date the stock certificate is issued, except as provided in Section 10 of
the Plan.

         Exercise of an Option in any manner shall result in a decrease in the
number of Shares which thereafter may be available, both for purposes of the
Plan and for sale under the Option, by the number of Shares as to which the
Option is exercised.

         (b) Rule 16b-3.  Options granted to Outside Directors must comply
             ----------
with the applicable provisions of Rule 16b-3 promulgated under the Exchange
Act or any successor thereto and shall contain such additional conditions or
restrictions as may be required thereunder to qualify

                                      -4-
<PAGE>
 
Plan transactions, and other transactions by Outside Directors that otherwise
could be matched with Plan transactions, for the maximum exemption from Section
16 of the Exchange Act.

          (c) Termination of Continuous Status as a Director.  Subject to
              ----------------------------------------------
Section 10 hereof, in the event an Optionee's status as a Director terminates
(other than upon the Optionee's death or total and permanent disability (as
defined in Section 22(e)(3) of the Code)), the Optionee may exercise his or
her Option, but only within three (3) months following the date of such
termination, and only to the extent that the Optionee was entitled to exercise
it on the date of such termination (but in no event later than the expiration
of its ten (10) year term). To the extent that the Optionee was not entitled
to exercise an Option on the date of such termination, and to the extent that
the Optionee does not exercise such Option (to the extent otherwise so
entitled) within the time specified herein, the Option shall terminate.

          (d) Disability of Optionee.  In the event Optionee's status as a
              ----------------------
Director terminates as a result of total and permanent disability (as defined
in Section 22(e)(3) of the Code), the Optionee may exercise his or her Option,
but only within twelve (12) months following the date of such termination, and
only to the extent that the Optionee was entitled to exercise it on the date
of such termination (but in no event later than the expiration of its ten (10)
year term). To the extent that the Optionee was not entitled to exercise an
Option on the date of termination, or if he or she does not exercise such
Option (to the extent otherwise so entitled) within the time specified herein,
the Option shall terminate.

          (e) Death of Optionee.  In the event of an Optionee's death, the
              -----------------
Optionee's estate or a person who acquired the right to exercise the Option by
bequest or inheritance may exercise the Option, but only within twelve (12)
months following the date of death, and only to the extent that the Optionee
was entitled to exercise it on the date of death (but in no event later than
the expiration of its ten (10) year term). To the extent that the Optionee was
not entitled to exercise an Option on the date of death, and to the extent
that the Optionee's estate or a person who acquired the right to exercise such
Option does not exercise such Option (to the extent otherwise so entitled)
within the time specified herein, the Option shall terminate.

    9.    Non-Transferability of Options.  The Option may not be sold, pledged,
          ------------------------------                                       
assigned, hypothecated, transferred, or disposed of in any manner other than by
will or by the laws of descent or distribution and may be exercised, during the
lifetime of the Optionee, only by the Optionee.

   10.    Adjustments Upon Changes in Capitalization, Dissolution, Merger or
          ------------------------------------------------------------------
Asset Sale.
- ---------- 

          (a) Changes in Capitalization.  Subject to any required action by the
              -------------------------                                        
shareholders of the Company, the number of Shares covered by each outstanding
Option, the number of Shares which have been authorized for issuance under the
Plan but as to which no Options have yet been granted or which have been
returned to the Plan upon cancellation or expiration of an Option, as well as
the price per Share covered by each such outstanding Option, and the number of
Shares issuable pursuant to the automatic grant provisions of Section 4 hereof
shall be proportionately adjusted for any increase or decrease in the number of
issued Shares resulting from a stock split, reverse stock

                                      -5-
<PAGE>
 
split, stock dividend, combination or reclassification of the Common Stock, or
any other increase or decrease in the number of issued Shares effected without
receipt of consideration by the Company; provided, however, that conversion of
any convertible securities of the Company shall not be deemed to have been
"effected without receipt of consideration." Except as expressly provided
herein, no issuance by the Company of shares of stock of any class, or
securities convertible into shares of stock of any class, shall affect, and no
adjustment by reason thereof shall be made with respect to, the number or price
of Shares subject to an Option.

     (b) Dissolution or Liquidation.  In the event of the proposed dissolution
         --------------------------                                           
or liquidation of the Company, to the extent that an Option has not been
previously exercised, it shall terminate immediately prior to the consummation
of such proposed action.

     (c) Merger or Asset Sale.  In the event of a merger of the Company with or
         --------------------                                                  
into another corporation or the sale of substantially all of the assets of the
Company, outstanding Options may be assumed or equivalent options may be
substituted by the successor corporation or a Parent or Subsidiary thereof (the
"Successor Corporation").  If an Option is assumed or substituted for, the
Option or equivalent option shall continue to be exercisable as provided in
Section 4 hereof for so long as the Optionee serves as a Director or a director
of the Successor Corporation.  Following such assumption or substitution, if the
Optionee's status as a Director or director of the Successor Corporation, as
applicable, is terminated other than upon a voluntary resignation by the
Optionee, the Option or option shall become fully exercisable, including as to
Shares for which it would not otherwise be exercisable.  Thereafter, the Option
or option shall remain exercisable in accordance with Sections 8(c) through (e)
above.

     If the Successor Corporation does not assume an outstanding Option or
substitute for it an equivalent option, the Option shall become fully vested and
exercisable, including as to Shares for which it would not otherwise be
exercisable.  In such event the Board shall notify the Optionee that the Option
shall be fully exercisable for a period of thirty (30) days from the date of
such notice, and upon the expiration of such period the Option shall terminate.

     For the purposes of this Section 10(c), an Option shall be considered
assumed if, following the merger or sale of assets, the Option confers the
right to purchase or receive, for each Share of Optioned Stock subject to the
Option immediately prior to the merger or sale of assets, the consideration
(whether stock, cash, or other securities or property) received in the merger
or sale of assets by holders of Common Stock for each Share held on the
effective date of the transaction (and if holders were offered a choice of
consideration, the type of consideration chosen by the holders of a majority
of the outstanding Shares). If such consideration received in the merger or
sale of assets is not solely common stock of the successor corporation or its
Parent, the Administrator may, with the consent of the successor corporation,
provide for the consideration to be received upon the exercise of the Option,
for each Share of Optioned Stock subject to the Option, to be solely common
stock of the successor corporation or its Parent equal in fair market value to
the per share consideration received by holders of Common Stock in the merger
or sale of assets.

  11.  Amendment and Termination of the Plan.
       ------------------------------------- 

       (a) Amendment and Termination.  Except as set forth in Section 4, the
           -------------------------
Board may at any time amend, alter, suspend, or discontinue the Plan, but no
amendment, alteration, suspension, or discontinuation shall be made which
would impair the rights of any Optionee under any grant theretofore made,
without his or her consent. In addition, to the extent necessary and desirable
to comply with Rule 16b-3 under the Exchange Act (or any other applicable law
or regulation), the Company shall obtain shareholder approval of any Plan
amendment in such a manner and to such a degree as required.

       (b) Effect of Amendment or Termination.  Any such amendment or
           ----------------------------------
termination of the Plan shall not affect Options already granted and such
Options shall remain in full force and effect as if this Plan had not been
amended or terminated.

  12.  Time of Granting Options.  The date of grant of an Option shall, for
       ------------------------                                            
all purposes, be the date determined in accordance with Section 4 hereof.

  13.  Conditions Upon Issuance of Shares.  Shares shall not be issued
       ----------------------------------                             
pursuant to the exercise of an Option unless the exercise of such Option and the
issuance and delivery of such Shares pursuant thereto shall comply with all
relevant provisions of law, including, without limitation, the Securities Act of
1933, as amended, the Exchange Act, the rules and regulations promulgated
thereunder, state securities laws, and the requirements of any stock exchange
upon which the Shares may then be listed, and shall be further subject to the
approval of counsel for the Company with respect to such compliance.

       As a condition to the exercise of an Option, the Company may require the
person exercising such Option to represent and warrant at the time of any such
exercise that the Shares are being purchased only for investment and without any
present intention to sell or distribute such Shares, if, in the opinion of
counsel for the Company, such a representation is required by any of the
aforementioned relevant provisions of law.

       Inability of the Company to obtain authority from any regulatory body
having jurisdiction, which authority is deemed by the Company's counsel to be
necessary to the lawful issuance and sale of any Shares hereunder, shall relieve
the Company of any liability in respect of the failure to issue or sell such
Shares as to which such requisite authority shall not have been obtained.

  14.  Reservation of Shares. The Company, during the term of this Plan, will
       ---------------------                                                 
at all times reserve and keep available such number of Shares as shall be
sufficient to satisfy the requirements of the Plan.

  15.  Option Agreement.  Options shall be evidenced by written option
       ----------------                                               
agreements in such form as the Board shall approve.

  16.  Shareholder Approval. Continuance of the Plan shall be subject to
       --------------------                                             
approval by the shareholders of the Company at or prior to the first annual
meeting of shareholders held subsequent to the granting of an Option
hereunder. Such shareholder approval shall be obtained in the degree and
manner required under applicable state and federal law and any stock exchange
rules.

                             TELEGEN CORPORATION

                          DIRECTOR OPTION AGREEMENT


     Telegen, a California corporation (the "Company"), has granted to
[_________________]  (the "Optionee"), an option to purchase a total of
[______________________ (________)] shares of the Company's Common Stock (the
"Optioned Stock"), at the price determined as provided herein, and in all
respects subject to the terms, definitions and provisions of the Company's 1996
Director Option Plan (the "Plan") adopted by the Company which is incorporated
herein by reference.  The terms defined in the Plan shall have the same defined
meanings herein.

     1.   Nature of the Option.  This Option is a nonstatutory option and is not
          --------------------

     2.   Exercise Price.  The exercise price is $[____________] for each share
          --------------                                                       
of Common Stock.

     3.   Exercise of Option.  This Option shall be exercisable during its term
          ------------------                                                   
in accordance
with the provisions of Section 8 of the Plan as follows:

          (i)  Right to Exercise.
               ----------------- 

               (a) This Option shall become exercisable in installments
cumulatively with respect to [______________ percent (____%)] of the Optioned
Stock one year after the date of grant, and as to an additional
[_______________ percent (____%)] of the Optioned Stock on each anniversary of
the date of grant, so that one hundred percent (100%) of the Optioned Stock
shall be exercisable [____] years after the date of grant; provided, however,
that in no event shall any Option be exercisable prior to the date the
stockholders of the Company approve the Plan.

               (b) This Option may not be exercised for a fraction of a share.

               (c) In the event of Optionee's death, disability or other
termination of service as a Director, the exercisability of the Option is
governed by Section 8 of the Plan.

          (ii) Method of Exercise.  This Option shall be exercisable by written
               ------------------                                              
notice which shall state the election to exercise the Option and the number of
Shares in respect of which the Option is being exercised.  Such written notice,
in the form attached hereto as Exhibit A, shall be signed by the Optionee and
shall be delivered in person or by certified mail to the Secretary of the
Company.  The written notice shall be accompanied by payment of the exercise
price.

     4.   Method of Payment.  Payment of the exercise price shall be by any of
          -----------------                                                   
the following or a combination thereof, at the election of the Optionee:

                                      -9-
<PAGE>
 
          (i)    cash;

          (ii)   check; or

          (iii)  surrender of other shares which (x) in the case of Shares
acquired upon exercise of an Option, have been owned by the Optionee for more
than six (6) months on the date of surrender, and (y) have a Fair Market Value
on the date of surrender equal to the aggregate exercise price of the Shares as
to which said Option shall be exercised; or

          (iv)   delivery of a properly executed exercise notice together with
such other documentation as the Company and the broker, if applicable, shall
require to effect an exercise of the Option and delivery to the Company of the
sale or loan proceeds required to pay the exercise price.

     5.   Restrictions on Exercise.  This Option may not be exercised if the
          ------------------------                                          
issuance of such Shares upon such exercise or the method of payment of
consideration for such shares would constitute a violation of any applicable
federal or state securities or other law or regulations, or if such issuance
would not comply with the requirements of any stock exchange upon which the
Shares may then be listed.  As a condition to the exercise of this Option, the
Company may require Optionee to make any representation and warranty to the
Company as may be required by any applicable law or regulation.

     6.   Non-Transferability of Option.  This Option may not be transferred in
          -----------------------------                                        
any manner otherwise than by will or by the laws of descent or distribution and
may be exercised during the lifetime of Optionee only by the Optionee.  The
terms of this Option shall be binding upon the executors, administrators, heirs,
successors and assigns of the Optionee.

     7.   Term of Option.  This Option may not be exercised more than ten (10)
          --------------                                                      
years from the date of grant of this Option, and may be exercised during such
period only in accordance with the Plan and the terms of this Option.

     8.   Taxation Upon Exercise of Option.  Optionee understands that, upon
          --------------------------------                                  
exercise of this Option, he or she will recognize income for tax purposes in an
amount equal to the excess of the then Fair Market Value of the Shares purchased
over the exercise price paid for such Shares.  Since the Optionee is subject to
Section 16(b) of the Securities Exchange Act of 1934, as amended, under certain
limited circumstances the measurement and timing of such income (and the
commencement of any capital gain holding period) may be deferred, and the
Optionee is advised to contact a tax advisor concerning the application of
Section 83 in general and the availability a Section 83(b) election in
particular in connection with the exercise of the Option.  Upon a resale of 

                                      -10-
<PAGE>
 
such Shares by the Optionee, any difference between the sale price and the
Fair Market Value of the Shares on the date of exercise of the Option, to the
extent not included in income as described above, will be treated as capital
gain or loss.

administered by different Committees with respect to different groups of
Service Providers.

<PAGE>
 
          (b) Powers of the Administrator.  Subject to the provisions of the
              ---------------------------
Plan, and in the case of a Committee, subject to the specific duties delegated
by the Board to such Committee, the Administrator shall have the authority, in
its discretion:

              (i)    to determine the Fair Market Value;

              (ii)   to select the Service Providers to whom Options and Stock
Purchase Rights may be granted hereunder;

              (iii)  to determine the number of shares of Common Stock to be
covered by each Option and Stock Purchase Right granted hereunder;

              (iv)   to approve forms of agreement for use under the Plan;

              (v)    to determine the terms and conditions, not inconsistent
with the terms of the Plan, of any Option or Stock Purchase Right granted
hereunder. Such terms and conditions include, but are not limited to, the
exercise price, the time or times when Options or Stock Purchase Rights may be
exercised (which may be based on performance criteria), any vesting
acceleration or waiver of forfeiture restrictions, and any restriction or
limitation regarding any Option or Stock Purchase Right or the shares of
Common Stock relating thereto, based in each case on such factors as the
Administrator, in its sole discretion, shall determine;

              (vi)   to reduce the exercise price of any Option or Stock
Purchase Right to the then current Fair Market Value if the Fair Market Value
of the Common Stock covered by such Option or Stock Purchase Right shall have
declined since the date the Option or Stock Purchase Right was granted;

              (vii)  to institute an Option Exchange Program;

              (viii) to construe and interpret the terms of the Plan and awards
granted pursuant to the Plan;

              (ix)   to prescribe, amend and rescind rules and regulations
relating to the Plan, including rules and regulations relating to sub-plans
established for the purpose of qualifying for preferred tax treatment under
foreign tax laws;

              (x)    to modify or amend each Option or Stock Purchase Right
(subject to Section 16(c) of the Plan), including the discretionary authority
to extend the post-termination exercisability period of Options longer than is
otherwise provided for in the Plan;

              (xi)   to allow Optionees to satisfy withholding tax obligations
by electing to have the Company withhold from the Shares to be issued upon
exercise of an Option or Stock Purchase Right that number of Shares having a
Fair Market Value equal to the amount required to be withheld. The Fair Market
Value of the Shares to be withheld shall be determined on the date that the
amount of tax to be withheld is to be determined. All elections by an Optionee
to have Shares 
<PAGE>
 
withheld for this purpose shall be made in such form and under such conditions
as the Administrator may deem necessary or advisable;

              (xii)  to authorize any person to execute on behalf of the
Company any instrument required to effect the grant of an Option or Stock
Purchase Right previously granted by the Administrator;

              (xiii) to make all other determinations deemed necessary or
advisable for administering the Plan.

          (c) Effect of Administrator's Decision.  The Administrator's
              ----------------------------------
decisions, determinations and interpretations shall be final and binding on
all Optionees and any other holders of Options or Stock Purchase Rights.

     5.   Eligibility.  Nonstatutory Stock Options and Stock Purchase Rights may
          -----------                                                           
be granted to Service Providers.  Incentive Stock Options may be granted only to
Employees.

     6.   Limitations.
          ----------- 

          (a)  Each Option shall be designated in the Option Agreement as
either an Incentive Stock Option or a Nonstatutory Stock Option. However,
notwithstanding such designation, to the extent that the aggregate Fair Market
Value of the Shares with respect to which Incentive Stock Options are
exercisable for the first time by the Optionee during any calendar year (under
all plans of the Company and any Parent or Subsidiary) exceeds $100,000, such
Options shall be treated as Nonstatutory Stock Options. For purposes of this
Section 6(a), Incentive Stock Options shall be taken into account in the order
in which they were granted. The Fair Market Value of the Shares shall be
determined as of the time the Option with respect to such Shares is granted.

          (b)  Neither the Plan nor any Option or Stock Purchase Right shall
confer upon an Optionee any right with respect to continuing the Optionee's
relationship as a Service Provider with the Company, nor shall they interfere
in any way with the Optionee's right or the Company's right to terminate such
relationship at any time, with or without cause.

          (c)  The following limitations shall apply to grants of Options:

               (i)    No Service Provider shall be granted, in any fiscal year
of the Company, Options to purchase more than one hundred thousand (100,000)
Shares.

               (ii)   In connection with his or her initial service, a Service
Provider may be granted Options to purchase up to an additional two hundred
thousand (200,000) Shares which shall not count against the limit set forth in
subsection (i) above.

               (iii)  The foregoing limitations shall be adjusted
proportionately in connection with any change in the Company's capitalization
as described in Section 14.
<PAGE>
 
               (iv)   If an Option is canceled in the same fiscal year of the
Company in which it was granted (other than in connection with a transaction
described in Section 14), the canceled Option will be counted against the
limits set forth in subsections (i) and (ii) above. For this purpose, if the
exercise price of an Option is reduced, the transaction will be treated as a
cancellation of the Option and the grant of a new Option.

     7.   Term of Plan.  Subject to Section 20 of the Plan, the Plan shall
          ------------                                                    
become effective upon its adoption by the Board.  It shall continue in effect
for a term of ten (10) years unless terminated earlier under Section 16 of the
Plan.

     8.   Term of Option.  The term of each Option shall be stated in the Option
          --------------                                                        
Agreement.  In the case of an Incentive Stock Option, the term shall be ten (10)
years from the date of grant or such shorter term as may be provided in the
Option Agreement.  Moreover, in the case of an Incentive Stock Option granted to
an Optionee who, at the time the Incentive Stock Option is granted, owns stock
representing more than ten percent (10%) of the total combined voting power of
all classes of stock of the Company or any Parent or Subsidiary, the term of the
Incentive Stock Option shall be five (5) years from the date of grant or such
shorter term as may be provided in the Option Agreement.

     9.   Option Exercise Price and Consideration.
          --------------------------------------- 

          (a) Exercise Price.  The per share exercise price for the Shares to be
              --------------                                                    
issued pursuant to exercise of an Option shall be determined by the
Administrator, subject to the following:

              (i)    In the case of an Incentive Stock Option

                     (A) granted to an Employee who, at the time the Incentive
Stock Option is granted, owns stock representing more than ten percent (10%)
of the voting power of all classes of stock of the Company or any Parent or
Subsidiary, the per Share exercise price shall be no less than 110% of the
Fair Market Value per Share on the date of grant.

                     (B) granted to any Employee other than an Employee
described in paragraph (A) immediately above, the per Share exercise price
shall be no less than 100% of the Fair Market Value per Share on the date of
grant.

              (ii)   In the case of a Nonstatutory Stock Option, the per Share
exercise price shall be determined by the Administrator. In the case of a
Nonstatutory Stock Option intended to qualify as "performance-based
compensation" within the meaning of Section 162(m) of the Code, the per Share
exercise price shall be no less than 100% of the Fair Market Value per Share
on the date of grant.

              (iii)  Notwithstanding the foregoing, Options may be granted
with a per Share exercise price of less than 100% of the Fair Market Value per
Share on the date of grant pursuant to a merger or other corporate
transaction.
<PAGE>
 
          (b) Waiting Period and Exercise Dates.  At the time an Option is
              ---------------------------------
granted, the Administrator shall fix the period within which the Option may be
exercised and shall determine any conditions which must be satisfied before
the Option may be exercised.

          (c) Form of Consideration.  The Administrator shall determine the
              ---------------------                                        
acceptable form of consideration for exercising an Option, including the method
of payment.  In the case of an Incentive Stock Option, the Administrator shall
determine the acceptable form of consideration at the time of grant.  Such
consideration may consist entirely of:

              (i)    cash;

              (ii)   check;

              (iii)  promissory note;

              (iv)   other Shares which (A) in the case of Shares acquired
upon exercise of an option, have been owned by the Optionee for more than six
months on the date of surrender, and (B) have a Fair Market Value on the date
of surrender equal to the aggregate exercise price of the Shares as to which
said Option shall be exercised;

              (v)    consideration received by the Company under a cashless
exercise program implemented by the Company in connection with the Plan;

              (vi)   a reduction in the amount of any Company liability to the
Optionee, including any liability attributable to the Optionee's participation
in any Company-sponsored deferred compensation program or arrangement;

              (vii)  any combination of the foregoing methods of payment; or

              (viii) such other consideration and method of payment for the
issuance of Shares to the extent permitted by Applicable Laws.
<PAGE>
 
     10.  Exercise of Option.
          ------------------ 

          (a)  Procedure for Exercise; Rights as a Shareholder. Any Option
               -----------------------------------------------
granted hereunder shall be exercisable according to the terms of the Plan and
at such times and under such conditions as determined by the Administrator and
set forth in the Option Agreement. Unless the Administrator provides
otherwise, vesting of Options granted hereunder shall be tolled during any
unpaid leave of absence. An Option may not be exercised for a fraction of a
Share.

               An Option shall be deemed exercised when the Company receives:
(i) written or electronic notice of exercise (in accordance with the Option
Agreement) from the person entitled to exercise the Option, and (ii) full
payment for the Shares with respect to which the Option is exercised. Full
payment may consist of any consideration and method of payment authorized by
the Administrator and permitted by the Option Agreement and the Plan. Shares
issued upon exercise of an Option shall be issued in the name of the Optionee
or, if requested by the Optionee, in the name of the Optionee and his or her
spouse. Until the Shares are issued (as evidenced by the appropriate entry on
the books of the Company or of a duly authorized transfer agent of the
Company), no right to vote or receive dividends or any other rights as a
shareholder shall exist with respect to the Optioned Stock, notwithstanding
the exercise of the Option. The Company shall issue (or cause to be issued)
such Shares promptly after the Option is exercised. No adjustment will be made
for a dividend or other right for which the record date is prior to the date
the Shares are issued, except as provided in Section 14 of the Plan.

               Exercising an Option in any manner shall decrease the number of
Shares thereafter available, both for purposes of the Plan and for sale under
the Option, by the number of Shares as to which the Option is exercised.

          (b)  Termination of Relationship as a Service Provider.  If an
               -------------------------------------------------
Optionee ceases to be a Service Provider, other than upon the Optionee's death
or Disability, the Optionee may exercise his or her Option within such period
of time as is specified in the Option Agreement to the extent that the Option
is vested on the date of termination (but in no event later than the
expiration of the term of such Option as set forth in the Option Agreement).
In the absence of a specified time in the Option Agreement, the Option shall
remain exercisable for three (3) months following the Optionee's termination.
If, on the date of termination, the Optionee is not vested as to his or her
entire Option, the Shares covered by the unvested portion of the Option shall
revert to the Plan. If, after termination, the Optionee does not exercise his
or her Option within the time specified by the Administrator, the Option shall
terminate, and the Shares covered by such Option shall revert to the Plan.

          (c)  Disability of Optionee.  If an Optionee ceases to be a Service
               ----------------------                                        
Provider as a result of the Optionee's Disability, the Optionee may exercise
his or her Option within such period of time as is specified in the Option
Agreement to the extent the Option is vested on the date of termination (but
in no event later than the expiration of the term of such Option as set forth
in the Option Agreement). In the absence of a specified time in the Option
Agreement, the Option shall remain exercisable for twelve (12) months
following the Optionee's termination. If, on the date of termination, the
Optionee is not vested as to his or her entire Option, the Shares covered by
the
<PAGE>
 
unvested portion of the Option shall revert to the Plan. If, after
termination, the Optionee does not exercise his or her Option within the time
specified herein, the Option shall terminate, and the Shares covered by such
Option shall revert to the Plan.

          (d)  Death of Optionee.  If an Optionee dies while a Service
               -----------------
Provider, the Option may be exercised within such period of time as is
specified in the Option Agreement (but in no event later than the expiration
of the term of such Option as set forth in the Notice of Grant), by the
Optionee's estate or by a person who acquires the right to exercise the Option
by bequest or inheritance, but only to the extent that the Option is vested on
the date of death. In the absence of a specified time in the Option Agreement,
the Option shall remain exercisable for twelve (12) months following the
Optionee's termination. If, at the time of death, the Optionee is not vested
as to his or her entire Option, the Shares covered by the unvested portion of
the Option shall immediately revert to the Plan. The Option may be exercised
by the executor or administrator of the Optionee's estate or, if none, by the
person(s) entitled to exercise the Option under the Optionee's will or the
laws of descent or distribution. If the Option is not so exercised within the
time specified herein, the Option shall terminate, and the Shares covered by
such Option shall revert to the Plan.

          (e)  Buyout Provisions.  The Administrator may at any time offer to
               -----------------
buy out for a payment in cash or Shares, an Option previously granted based on
such terms and conditions as the Administrator shall establish and communicate
to the Optionee at the time that such offer is made.

     11.  Stock Purchase Rights.
          --------------------- 

          (a)  Rights to Purchase.  Stock Purchase Rights may be issued either
               ------------------
alone, in addition to, or in tandem with other awards granted under the Plan
and/or cash awards made outside of the Plan. After the Administrator
determines that it will offer Stock Purchase Rights under the Plan, it shall
advise the offeree in writing or electronically, by means of a Notice of
Grant, of the terms, conditions and restrictions related to the offer,
including the number of Shares that the offeree shall be entitled to purchase,
the price to be paid, and the time within which the offeree must accept such
offer. The offer shall be accepted by execution of a Restricted Stock Purchase
Agreement in the form determined by the Administrator.

          (b)  Repurchase Option.  Unless the Administrator determines
               -----------------
otherwise, the Restricted Stock Purchase Agreement shall grant the Company a
repurchase option exercisable upon the voluntary or involuntary termination of
the purchaser's service with the Company for any reason (including death or
Disability). The purchase price for Shares repurchased pursuant to the
Restricted Stock purchase agreement shall be the original price paid by the
purchaser and may be paid by cancellation of any indebtedness of the purchaser
to the Company. The repurchase option shall lapse at a rate determined by the
Administrator.

          (c)  Other Provisions.  The Restricted Stock Purchase Agreement shall
               ----------------                                                
contain such other terms, provisions and conditions not inconsistent with the
Plan as may be determined by the Administrator in its sole discretion.
<PAGE>
 
          (d)  Rights as a Shareholder.  Once the Stock Purchase Right is
exercised, the purchaser shall have the rights equivalent to those of a
shareholder, and shall be a shareholder when his or her purchase is entered
upon the records of the duly authorized transfer agent of the Company. No
adjustment will be made for a dividend or other right for which the record
date is prior to the date the Stock Purchase Right is exercised, except as
provided in Section 14 of the Plan.

     12.  Stock Awards.
          ------------ 

          (a)  Administration.  Stock Awards may be granted alone or in
addition to other Option grants or Stock Purchase Rights granted under the
Plan. Such Stock Awards shall be granted for no cash consideration. The
Administrator shall determine the nature, length and starting date of any
performance period (the "Performance Period"), and shall determine the
performance or employment factors, if any, to be used in the determination of
the Stock Award and the extent to which such Stock Award is valued or has been
earned. After the Administrator determines that it will offer a Stock Award
under the Plan, it shall advise the offeree in writing or electronically, by
means of a Notice of Stock Award, of the terms, conditions and restrictions
related to the offer, including the number of Shares that the offeree shall be
entitled to purchase, the price to be paid, and the time within which the
offeree must accept such offer. Stock Awards may be granted before, during, or
after a given Performance Period. Stock Awards may vary from participant to
participant and between groups of participants. Stock Awards shall be
confirmed by, and be subject to the terms of, a Stock Award Agreement.

          (b)  Adjustment of Awards.  The Administrator may adjust the
               --------------------
performance factors applicable to the Stock Award to take into account changes
in legal, accounting and tax rules and to make such adjustments as the
Administrator deems necessary or appropriate to reflect the inclusion or
exclusion of the impact of extraordinary or unusual items, events, or
circumstances in order to avoid windfalls or hardships.

     13.  Non-Transferability of Options and Stock Purchase Rights.  Unless
          --------------------------------------------------------         
determined otherwise by the Administrator, an Option or Stock Purchase Right may
not be sold, pledged, assigned, hypothecated, transferred, or disposed of in any
manner other than by will or by the laws of descent or distribution and may be
exercised, during the lifetime of the Optionee, only by the Optionee.  If the
Administrator makes an Option or Stock Purchase Right transferable, such Option
or Stock Purchase Right shall contain such additional terms and conditions as
the Administrator deems appropriate.

     14.  Adjustments Upon Changes in Capitalization, Dissolution, Merger or
          ------------------------------------------------------------------
    Asset Sale.
    ---------- 

          (a)  Changes in Capitalization.  Subject to any required action by the
               -------------------------                                        
shareholders of the Company, the number of shares of Common Stock covered by
each outstanding Option and Stock Purchase Right, and the number of shares of
Common Stock which have been authorized for issuance under the Plan but as to
which no Options or Stock Purchase Rights have yet been granted or which have
been returned to the Plan upon cancellation or expiration of an Option or
Stock Purchase Right, as well as the price per share of Common Stock covered
by each such outstanding Option or Stock Purchase Right, shall be
proportionately adjusted for any increase or decrease in the
<PAGE>
 
number of issued shares of Common Stock resulting from a stock split, reverse
stock split, stock dividend, combination or reclassification of the Common
Stock, or any other increase or decrease in the number of issued shares of
Common Stock effected without receipt of consideration by the Company;
provided, however, that conversion of any convertible securities of the
Company shall not be deemed to have been "effected without receipt of
consideration." Such adjustment shall be made by the Board, whose
determination in that respect shall be final, binding and conclusive. Except
as expressly provided herein, no issuance by the Company of shares of stock of
any class, or securities convertible into shares of stock of any class, shall
affect, and no adjustment by reason thereof shall be made with respect to, the
number or price of shares of Common Stock subject to an Option or Stock
Purchase Right.

          (b)  Dissolution or Liquidation.  In the event of the proposed
               --------------------------
dissolution or liquidation of the Company, the Administrator shall notify each
Optionee as soon as practicable prior to the effective date of such proposed
transaction. The Administrator in its discretion may provide for an Optionee
to have the right to exercise his or her Option until ten (10) days prior to
such transaction as to all of the Optioned Stock covered thereby, including
Shares as to which the Option would not otherwise be exercisable. In addition,
the Administrator may provide that any Company repurchase option applicable to
any Shares purchased upon exercise of an Option or Stock Purchase Right shall
lapse as to all such Shares, provided the proposed dissolution or liquidation
takes place at the time and in the manner contemplated. To the extent it has
not been previously exercised, an Option or Stock Purchase Right will
terminate immediately prior to the consummation of such proposed action.

          (c)  Merger or Asset Sale.  In the event of a merger of the Company
with or into another corporation, or the sale of substantially all of the
assets of the Company, each outstanding Option and Stock Purchase Right shall
be assumed or an equivalent option or right substituted by the successor
corporation or a Parent or Subsidiary of the successor corporation. In the
event that the successor corporation refuses to assume or substitute for the
Option or Stock Purchase Right, the Optionee shall fully vest in and have the
right to exercise the Option or Stock Purchase Right as to all of the Optioned
Stock, including Shares as to which it would not otherwise be vested or
exercisable. If an Option or Stock Purchase Right becomes fully vested and
exercisable in lieu of assumption or substitution in the event of a merger or
sale of assets, the Administrator shall notify the Optionee in writing or
electronically that the Option or Stock Purchase Right shall be fully vested
and exercisable for a period of fifteen (15) days from the date of such
notice, and the Option or Stock Purchase Right shall terminate upon the
expiration of such period. For the purposes of this paragraph, the Option or
Stock Purchase Right shall be considered assumed if, following the merger or
sale of assets, the option or right confers the right to purchase or receive,
for each Share of Optioned Stock subject to the Option or Stock Purchase Right
immediately prior to the merger or sale of assets, the consideration (whether
stock, cash, or other securities or property) received in the merger or sale
of assets by holders of Common Stock for each Share held on the effective date
of the transaction (and if holders were offered a choice of consideration, the
type of consideration chosen by the holders of a majority of the outstanding
Shares); provided, however, that if such consideration received in the merger
or sale of assets is not solely common stock of the successor corporation or
its Parent, the Administrator may, with the consent of the successor
corporation, provide for the consideration to be received upon the exercise of
the Option or Stock Purchase Right, for each Share
<PAGE>
 
of Optioned Stock subject to the Option or Stock Purchase Right, to be solely
common stock of the successor corporation or its Parent equal in fair market
value to the per share consideration received by holders of Common Stock in
the merger or sale of assets.

    15.   Date of Grant.  The date of grant of an Option or Stock Purchase Right
          -------------                                                         
shall be, for all purposes, the date on which the Administrator makes the
determination granting such Option or Stock Purchase Right, or such other later
date as is determined by the Administrator.  Notice of the determination shall
be provided to each Optionee within a reasonable time after the date of such
grant.

     16.  Amendment and Termination of the Plan.
          ------------------------------------- 

          (a) Amendment and Termination.  The Board may at any time amend,
              -------------------------                                   
alter, suspend or terminate the Plan.

          (b) Shareholder Approval.  The Company shall obtain shareholder
              --------------------
approval of any Plan amendment to the extent necessary and desirable to comply
with Applicable Laws.

          (c) Effect of Amendment or Termination.  No amendment, alteration,
              ----------------------------------                            
suspension or termination of the Plan shall impair the rights of any Optionee,
unless mutually agreed otherwise between the Optionee and the Administrator,
which agreement must be in writing and signed by the Optionee and the Company.
Termination of the Plan shall not affect the Administrator's ability to exercise
the powers granted to it hereunder with respect to options granted under the
Plan prior to the date of such termination.

     17.  Conditions Upon Issuance of Shares.
          ---------------------------------- 

          (a) Legal Compliance.  Shares shall not be issued pursuant to the
              ----------------
exercise of an Option or Stock Purchase Right unless the exercise of such
Option or Stock Purchase Right and the issuance and delivery of such Shares
shall comply with Applicable Laws and shall be further subject to the approval
of counsel for the Company with respect to such compliance.

          (b) Investment Representations.  As a condition to the exercise of an
              --------------------------                                       
Option or Stock Purchase Right, the Company may require the person exercising
such Option or Stock Purchase Right to represent and warrant at the time of any
such exercise that the Shares are being purchased only for investment and
without any present intention to sell or distribute such Shares if, in the
opinion of counsel for the Company, such a representation is required.

     18.  Inability to Obtain Authority.  The inability of the Company to obtain
          -----------------------------                                         
authority from any regulatory body having jurisdiction, which authority is
deemed by the Company's counsel to be necessary to the lawful issuance and
sale of any Shares hereunder, shall relieve the Company of any liability in
respect of the failure to issue or sell such Shares as to which such requisite
authority shall not have been obtained.
<PAGE>
 
     19.  Reservation of Shares.  The Company, during the term of this Plan,
          ---------------------                                             
will at all times reserve and keep available such number of Shares as shall be
sufficient to satisfy the requirements of the Plan.

     20.  Shareholder Approval.  The Plan shall be subject to approval by the
          --------------------                                               
shareholders of the Company within twelve (12) months after the date the Plan is
adopted.  Such shareholder approval shall be obtained in the manner and to the
degree required under Applicable Laws.

     21.  Effective Date of the Plan.  The Plan shall become effective upon
          --------------------------                                       
completion of the merger of Telegen Corporation, a California corporation, with
Solar Energy Research Corp., a Colorado corporation ("SERC") as contemplated in
Amendment No. 2 to the SEC Registration Statement on Form S-4, filed with the
Securities and Exchange Commission on August 21, 1996.

                    RE:     REGISTRATION STATEMENT ON FORM S-8

Ladies and Gentlemen:

     We have examined the Registration Statement on Form S-8 (the "Registration
Statement") to be filed by Telegen Corporation, a California corporation (the
"Company" or "you"), with the Securities and Exchange Commission on or about
December 6, 1996 in connection with the registration under the Securities Act
of 1933, as amended (the "Act"), of an aggregate of: (A) 1,004,283 shares of
Common Stock reserved for issuance upon exercise of options granted on or before
September 26, 1996 pursuant to the Company's form of Employee Stock Option
Agreement, (B) 61,000 shares of Common Stock reserved for issuance upon exercise
of options granted on or before September 26, 1996 pursuant to the Company's
form of Outside Director Stock Option Agreement,  (C) 300,000 shares of Common
Stock reserved for issuance under the Company's 1996 Director Option Plan, (D)
200,000 shares of Common Stock reserved for issuance under the Company's 1996
Employee Stock Purchase Plan and (E) 500,000 shares of Common Stock reserved for
issuance under the Company's 1996 Stock Plan (collectively, the "Plans") (all
such shares of Common Stock being hereinafter referred to as the "Shares").  As
your legal counsel, we have reviewed the actions pro  posed to be taken by you
in connection with the proposed sale and issuance of the Shares by the Company
under the Plans.

     It is our opinion that, upon completion of the actions being taken, or
contemplated by us as your counsel to be taken, by you prior to the issuance of
the Shares pursuant to the Registration Statement and the Plans, the 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 and any subsequent amendment thereto.

                         Very truly yours,
