                            TO PURCHASE COMMON STOCK

                                                       San Francisco, California
U.S.$200,000                                            April 30, 1997


         U.S. ELECTRICAR,  INC., a California  corporation (the "Company"),  the
principal  office of which is located at 5 Thomas Mellon  Circle,  Ste. 254, San
Francisco,  CA  94134,  for  value  received  hereby  promises  to pay to FONTAL
INTERNATIONAL,  LTD., or  registered  assigns,  the sum of Two Hundred  Thousand
Dollars  ($200,000.00) or such lesser amount as shall then equal the outstanding
principal amount hereof on the terms and conditions set forth  hereinafter.  The
principal  hereof and any unpaid accrued  interest  hereon,  as set forth below,
shall be due and  payable  on July 9,  1997 (the "Due  Date").  Payment  for all
amounts  due  hereunder  shall be made at the  election  of the  Company by wire
transfer,  as instructed by the Holder, or by mail to the registered  address of
the Holder. The Holder of the Bond is subject to certain  restrictions set forth
in the  Subscription  Agreement  and shall be  entitled  to  certain  rights and
privileges set forth in the Subscription Agreement.

         The  following  is a statement of the rights of the Holder of this Bond
and the  conditions  to which  this Bond is  subject,  and to which  the  Holder
hereof, by the acceptance of this Bond, agrees:

         1. Definitions.  As used in this Bond, the following terms,  unless the
context otherwise requires, have the following meanings:

                  a. "Company"  includes any corporation  which shall succeed to
or assume the obligations of the Company under this Bond.

                  b. "Holder," when the context refers to a holder of this Bond,
shall  mean any person  who shall at the time be the  registered  holder of this
Bond.

                                       20


         2. Interest.  Until all outstanding principal and interest on this Bond
shall  have been paid in full,  interest  shall be  payable  on the  outstanding
principal  balance of this Bond,  in arrears on the Due Date, at the rate of ten
percent (10.0%) per annum accruing from January 15, 1997.

         3.  Prepayment.  The  Company  may  prepay  any  portion  or all of the
principal  balance or interest  of this Bond upon ten (10) days'  prior  written
notice.  Any  prepayment  of this Bond will be credited  first  against  accrued
interest then principal.

         4. Conversion.

                  a.  Holder's  Conversion  Rights.  So  long  as any  principal
remains  outstanding  hereunder up to and through the Due Date (the  "Conversion
Period"),  Holder may, at its option by written  notice to the Company,  convert
all or any part of the  principal  and interest due  hereunder in  increments of
$100,000 or more (or such  lesser  amount as may remain  outstanding  under this
Bond at the time of conversion) into Common Stock of the Company at Thirty Cents
($0.30) per share.

                  b. General Conversion Terms. Upon Holder's election to convert
this Bond, the applicable  amount of outstanding  principal and interest of this
Bond shall be converted  so long as such  conversion  is exempt from  applicable
state and federal  registration  requirements  and the terms and  conditions set
forth below. The Company shall not be obligated to issue certificates evidencing
the shares of the securities  issuable upon such conversion  unless this Bond is
either  delivered to the Company or its transfer  agent,  or the Holder notifies
the  Company  or its  transfer  agent  that such Bond has been  lost,  stolen or
destroyed and executes an agreement and provides collateral  satisfactory to the
Company to indemnify the Company from any loss incurred by it in connection with
such Bond. The Company shall,  as soon as  practicable  after such delivery,  or
such  agreement  and  indemnification,  issue and deliver at such office to such
Holder of such Bond, a certificate or  certificates  for the securities to which
the Holder shall be entitled  accompanied by appropriate  restrictive legends on
transfer,  a check  payable  to the  Holder in the  amount  of any cash  amounts
payable as the result of a conversion into fractional shares of Common Stock, as
the case may be, and a new Bond upon the same terms this Bond for any  remaining
principal  in the case of a  conversion  of only a portion  of this  Bond.  Such
conversion shall be deemed to have been made  immediately  prior to the close of
business  of the date of  receipt  of  written  notice  by the  Company  causing
conversion. The person or persons entitled to receive Common Stock issuable upon
such  conversion  shall be treated  for all  purposes  and the record  Holder or
Holders of such Common Stock on such date.

         5. Bond Confers No Rights of Shareholder. The Holder shall not have any
rights as a  shareholder  of the  Company  with  regard to the  shares  issuable
hereunder prior to actual conversion hereunder.

         6.  Reservation  of Shares.  The Company agrees at all times during the
Conversion Period to have authorized and reserved,  for the exclusive purpose of
issuance  and delivery  upon  conversion  of this Bond,  a sufficient  number of
shares  of its  Common  Sock  to  provide  for  the  conversion  of  the  rights
represented hereby to the extent ascertainable.

         7. Adjustments. If the Company at any time during the Conversion Period
shall, by subdivision,  combination or re-classification  of securities,  change
any of the Company's Common Stock to which purchase rights under this Bond exist
into the same or different

                                       21



number of securities of any class or classes, this Bond shall thereafter entitle
the Holder to acquire  such  number  and kind of  securities  as would have been
issuable  as a result  of such  change  with  respect  to the  shares  hereunder
immediately prior to such subdivision,  combination,  or  re-classification.  If
shares of the Company's  Common Stock are  subdivided  into a greater  number of
shares of Common  Stock,  the  conversion  price for the shares  hereunder  upon
conversion  of this Bond shall be  proportionately  reduced  and such  shares be
proportionately  increased;  and conversely,  if shares of the Company's  Common
Stock are combined into a smaller number of Common Stock shares, the price shall
be  proportionately  increased,  and the Common Stock shares  hereunder shall be
proportionately decreased.

         8. Public Offering  Lock-Up.  For a period of up to  one-hundred-eighty
(180) days (the  "Stand-off  Period"),  Holder  shall not, if  requested  by the
Company at any time in contemplation of a public  registration,  sell, pledge or
otherwise  transfer any capital  stock  acquired  hereunder (or any other shares
exchanged therefor),  if this Bond has been converted,  to any person or entity.
Notwithstanding  the  foregoing,  this  lock-up  right may be  exercised  by the
Company only one time.

         9.  Assignment.  Subject  to any  restrictions  on  transfer  described
elsewhere  herein,  the rights and  obligations of the Company and the Holder of
this Bond shall be binding  upon and benefit  the  successors,  assigns,  heirs,
administrators and transferees of the parties hereto.

         10. Transfer of this Bond or Securities  Issuable on Conversion Hereof.
With  respect  to any  offer,  sale or  other  disposition  of this  Bond or any
underlying securities,  the Holder will give written notice to the Company prior
thereto,  describing briefly the manner thereof, together with a written opinion
of such  Holder's  counsel,  to the  effect  that  such  offer,  sale  or  other
distribution  may be effected without  registration or qualification  (under any
federal or state law than in effect,  including  but not limited to Regulation S
under the Securities Act of 1933, as amended (the "Act")).  Furthermore, no such
transfer shall be made unless the transferee meets the same investor suitability
standards set forth in the Subscription Agreement.  Promptly upon receiving such
written  notice  and  reasonably  satisfactory  opinion,  if so  requested,  the
Company,  as promptly as practicable,  shall notify such Holder that such Holder
may sell or otherwise dispose of this Bond or the underlying securities,  as the
case may be, all in accordance with the terms of the written notice delivered to
the Company.  If a determination has been made pursuant to this Section that the
opinion of counsel for the Holder is not reasonably satisfactory to the Company,
the Company shall so notify the Holder  promptly  after such  determination  has
been  made.  Each Bond or  underlying  securities  thus  transferred  shall bear
legends as to the applicable  restrictions on transferability in order to ensure
compliance  with the Act,  unless in the opinion of counsel for the Company such
legend is not required in order to ensure  compliance  with the Act. The Company
may issue stop transfer  instructions  to its transfer agent in connection  with
such restriction.

         11.  Notices.  All notices,  requests,  demands,  instructions or other
communications  required  or  permitted  to be given under this Bond shall be in
writing and shall be deemed to have been duly given upon delivery,  if delivered
personally, or if given by prepaid telegram, or if mailed from and to an address
in North America (Canada,  United States or Mexico) mailed first-class,  postage
prepaid, registered or certified mail, return receipt requested, shall be deemed
to have been given five (5) days after such  delivery,  to the address set forth
in the  Subscription  Agreement.  Either  party hereto may change the address to
which such  communications  are to be directed by giving  written  notice to the
other party hereto of such change in the manner above provided.


                                       22


         12.  Governing Law. This Agreement  shall be governed by, and construed
in accordance with, the laws of the State of California, applicable to contracts
between California  residents entered into and to be performed entirely with the
State of California.  Venue for all purposes in connection  with this Bond shall
be San Francisco, California.

         13.  Attorney's Fees. If any action at law or in equity is necessary to
enforce or  interpret  the terms of this Bond,  the  prevailing  party  shall be
entitled to reasonable  attorneys' fees, costs and  disbursements in addition to
any other relief to which such party may be entitled.

         14.  Heading;  References.  All  headings  used  herein  are  used  for
convenience only and shall not be used to construe or interpret this Bond.

         IN WITNESS WHEREOF, the Company has caused this Bond to be issued as of
the date first set forth above.
