                        FORM OF STOCK OPTION AGREEMENT

         THIS AGREEMENT, dated as of October 29, 2001, is made by and between
Spanish Broadcasting System, Inc. a Delaware corporation (the "Company") and
Carl Parmer (the "Optionee").

         WHEREAS, the Optionee has been selected by the Board to receive a grant
of stock options under the Spanish Broadcasting System 1999 Stock Option Plan
for Nonemployee Directors (the "Plan").

         NOW, THEREFORE, in consideration of the Optionee's agreement to serve
on the Board, the Company and the Optionee agree as follows:

         1. Definitions.

         Any capitalized term not defined herein shall have the meaning set
forth in the Plan.

         2. Grant of Option.

         (a) Grant; Grant Date. Subject to the terms and conditions hereof, the
Company hereby grants to the Optionee as of October 29, 2001 (the "Grant Date"),
an Option to purchase 50,000 Shares at an exercise price of $7.50, the Fair
Market Value of a Share as of October 29, 2001.

         (b) Adjustments in Option. In the event that the outstanding Shares
subject to the Option are changed into or exchanged for a different number or
kind of shares or securities of the Company, or of another corporation, by
reason of reorganization, merger or other subdivision, consolidation,
recapitalization, reclassification, stock split, issuance of warrants, stock
dividend or combination of shares or similar event, the Board shall make an
appropriate and equitable adjustment in the Option so that the Optionee's
proportionate interest shall be maintained as before the occurrence of such
event, provided that any such adjustment shall be consistent with the provisions
of the Optionee's employment agreement, if applicable.

         (c) Form of Option. The Option is intended to be a Nonqualified Stock
Option, and not an Incentive Stock Option.

         (d) Term. The Option shall expire on the tenth anniversary of the Grant
Date, unless terminated earlier by the Committee.

         (e) Vesting. Twenty percent (20%) of the Option shall be vested and
exercisable immediately as of the Grant Date; an additional twenty percent (20%)
of the Option shall vest and become exercisable on each of the first four
anniversaries of the Grant Date, provided that the Optionee is still a member of
the Board on such vesting dates.
<PAGE>
         (f) Exercise. The Optionee may exercise an Option in whole or in part
at any time by delivering written notice of such exercise to the Secretary of
the Company of the number of Shares as to which the Option is being exercised,
and enclosing payment for the Shares with respect to which the Option is being
exercised. Such payment shall be in cash or by check, or if approved by the
Committee, by the delivery of Shares previously owned by the Employee, duly
endorsed for transfer to the Company, with a Fair Market Value on the date of
delivery equal to the aggregate purchase price of the Shares with respect to
which the Option is being exercised, or pursuant to a "cashless exercise," or
any combination of the foregoing approved by the Committee, in its sole
discretion. Partial exercise shall be for whole Shares only and shall not be for
less than one hundred (100) Shares unless the number of Shares purchased
constitutes the total number of Shares then remaining subject to the Option or
the Committee permits such smaller exercise in its sole discretion.

         (g) Exercise Following Termination of Employment. If the Optionee
ceases to be a member of the Board, all outstanding Options shall be exercisable
by the Optionee (or his personal representative or beneficiary) for the
remainder of their original term, and shall thereafter terminate and have no
further force or effect.

         (h) Nontransferability. The Option shall not be transferable other than
by will or the laws of descent and distribution, and no transfer so effected
shall be effective to bind the Company unless the Company has been furnished
with written notice thereof and a copy of the will and/or such other evidence as
the Committee may deem necessary to establish the validity of the transfer and
the acceptance by the transferee or transferees of the terms and conditions of
the Option, provided, however, that, in the discretion of the Committee, Options
may be transferred pursuant to a Qualified Domestic Relations Order (within the
meaning of the Code).

         (i) Conditions to Issuance of Stock Certificates.

            (1) The Shares deliverable upon the exercise of the Option, or any
portion thereof, may be either previously authorized but unissued Shares or
issued Shares which have been reacquired by the Company. Such Shares shall be
fully paid and non-assessable. The stock certificates evidencing the Shares
shall bear such legends restricting transferability as the Committee deems
necessary or advisable.

            (2) The Company shall not be required to issue or deliver any
certificate or certificates for Shares deliverable upon any exercise of the
Option prior to fulfillment of all of the following conditions:

                                       2
<PAGE>
            (A) The completion of any registration or other qualification of
such Shares under any state or federal law or under rulings or regulations of
the Securities and Exchange Commission or of any other governmental regulatory
body, or the obtaining of approval or other clearance from any state or federal
governmental agency which the Committee shall, in its sole discretion, deem
necessary or advisable.

            (B) If, in its sole discretion, the Committee deems it necessary or
advisable, the execution by the Optionee of a written representation and
agreement, in a form satisfactory to the Committee, in which the Optionee
represents that the Shares acquired by him upon exercise are being acquired for
investment and not with a view to distribution thereof.

         (j) Rights as Stockholder. The Optionee shall not be, nor have any of
the rights or privileges of, a stockholder of the Company in respect of any
Shares purchasable upon the exercise of the Option unless and until certificates
representing such Shares have been issued by the Company.

         3. Miscellaneous.

         (a) Administration. The Committee shall have the power to interpret the
Plan and this Agreement, and to adopt such rules for the administration,
interpretation and application of the Plan as are consistent therewith and to
interpret or revoke any such rules. All actions taken and all interpretations
and determinations made by the Committee shall be final and binding upon the
Optionee, the Company, and all other interested persons.

         (b) Withholding of Taxes. No later than the date as of which an amount
first becomes includible in the gross income of the Optionee for federal income
tax purposes with respect to the grant of the Option under this Agreement, the
Optionee shall pay to the Company, or the Optionee (or his Designated
Beneficiary) shall make arrangements satisfactory to the Company regarding the
payment of, any federal, state, or local taxes of any kind required by law or
the Company to be withheld with respect to such amount. The obligations of the
Company under this Agreement shall be conditioned on such payment or
arrangements, and the Company shall, to the extent permitted by law, have the
right to deduct any such taxes from any payment of any kind otherwise due to the
Optionee.

         (c) No Right to Continued Board Status. Nothing in this Agreement or in
the Plan shall confer upon the Optionee any right to continue as a member of the
Board.

         (d) Entire Agreement; Amendment. This Agreement, and the Plan,
constitute the entire agreement between the parties with respect to the subject
matter hereof, and supersedes all prior agreements and understandings between

                  (a) Request by Holders. If the Company shall receive a
written request from a Holder that the Company file a Registration Statement
under the Securities Act covering the registration of Registrable Securities
pursuant to this Section 2.1 (a "Holder Notice"), then the Company shall, within
10 Business Days of the receipt of such Holder Notice, give written notice of
such request ("Company Notice") to all Holders. The Holders shall, within 20
days after receipt of the Company Notice, deliver written notice to the Company
of the number of Registrable Securities that Holders electing to participate in
the demand rights under this Section 2.1(a) ("Inclusion Notice"), and the
Company shall use its commercially reasonable efforts to effect, as soon as
practicable, the registration under the Securities Act of all Registrable
Securities that Holders request to be registered in the Inclusion Notice,
subject only to the limitations of this Section 2.1. Notwithstanding the
foregoing and provided that SJMB, L.P. shall be entitled to one demand
registration under this Section 2.1 regardless of its percentage of the
Registrable Securities Then Outstanding, the Company shall not be required to
effect a registration under this Section 2.1(a) if (x) the Registrable
Securities requested by all Holders to be registered in the Inclusion Notice is
less than 8% of the Registrable Securities Then Outstanding, (y) the Company
has, within the six month period preceding the date of such request, already
effected a registration under the Securities Act pursuant to this Section 2.1,
or in which the Holders had an opportunity to participate pursuant to the
provisions of Section 2.2, other than a registration from which the Registrable
Securities of Holders have been excluded (with respect to all or any portion of
the Registrable Securities the Holders requested be included in such
registration) pursuant to the provisions of Section 2.2(a) or (z) at the time of
the Company's receipt of the Holder Notice, the filing of the Registration
Statement or at any time during which the Registration Statement is effective,
the Company is not eligible to

                                       3
<PAGE>

register ("S-3 Eligible") the resale of shares by Holders on Form S-3 under
General Instructions I.A and I.B.3 to Form S-3 (or applicable successor form).

                  (b) Underwriting. If the Holders initiating the registration
request under this Section 2.1 ("Initiating Holders") intend to distribute the
Registrable Securities covered by their request by means of an underwriting,
then they shall so advise the Company as a part of the Holder Notice and the
Company shall include such information in the Company Notice. In such event, the
right of any Holder to include his Registrable Securities in such registration
shall be conditioned upon such Holder's participation in such underwriting and
the inclusion of such Holder's Registrable Securities in the underwriting
(unless otherwise mutually agreed by a majority in interest of the Initiating
Holders and such Holder) to the extent provided herein. All Holders proposing to
distribute their securities through such underwriting shall enter into an
underwriting agreement in customary form with the managing underwriter or
underwriters selected for such underwriting by the Holders of a majority of the
Registrable Securities and reasonably acceptable to the Company. Notwithstanding
any other provision of this Section 2.1, if the underwriter(s) advise(s) the
Company in writing that marketing factors require a limitation of the number of
securities to be underwritten then the Company shall so advise all Holders of
Registrable Securities which would otherwise be registered and underwritten
pursuant hereto, and the number of Registrable Securities that may be included
in the underwriting shall be reduced as required by the underwriter(s) and
allocated among the Holders of Registrable Securities on a pro rata basis
according to the number of Registrable Securities then outstanding held by each
Holder requesting registration under this Section 2.1 (including the Initiating
Holders); provided, however, that the number of shares of Registrable Securities
to be included in such underwriting and registration shall not be reduced unless
(i) all Registrable Securities held by Holders requesting registration under
Section 2.2 are first entirely excluded from the underwriting and registration
on a pro rata basis based on the total number of Registrable Securities then
held by each such Holder; and (ii) all other securities of the Company (whether
being sold by the Company or otherwise) are then entirely excluded from the
underwriting and registration. Any Registrable Securities excluded and withdrawn
from such underwriting shall be withdrawn from the registration. For any Holder
that is a partnership, the Holder and the partners and retired partners of such
Holder, or the estates and family members of any such partners and retired
partners and any trusts for the benefit of any of the foregoing persons, and for
any Holder that is a corporation, the Holder and all corporations that are
affiliates of such Holder, shall be deemed to be a single "Holder," and any pro
rata reduction with respect to such "Holder" shall be based upon the aggregate
amount of shares carrying registration rights owned by all entities and
individuals included in such "Holder," as defined in this sentence. If any such
registration, as a result of a reduction at the request of an underwriter, does
not include at least 8% of the Registrable Securities Then Outstanding, such
registration shall not constitute a demand for purposes of Section 2.1(d).

                  (c) Shelf Registration. Any registration requested under
Section 2.1(a) shall be effected on Form S-3 pursuant to Rule 415 under the
Securities Act (or its successor) on a continuous basis for the period requested
(a "Shelf Registration"). Under the Shelf Registration, the Company shall be
entitled to require that a Holder or Holders refrain from effecting any public
sales or distributions of the Registrable Securities pursuant to a Registration
Statement, if the Board reasonably determines that such public sales or
distributions would interfere in any material respect

                                       4
<PAGE>

with any transaction involving the Company that the Board reasonably determines
to be material to the Company. The Board shall, as promptly as practicable, give
the Holders written notice of any such development. In the event of a request by
the Board that Holders refrain from effecting any public sales or distributions
of the Registrable Securities, the Company shall be required to lift such
restrictions regarding effecting public sales or distributions of the
Registrable Securities as soon as reasonably practicable after the Board shall
reasonably determine public sales or distributions by Holders shall not
interfere with such transaction, provided, that in no event shall any
requirement that Holders refrain from effecting public sales or distributions in
the Registrable Securities extend for more than 90 days; provided, however, that
the Company may not utilize this right more than once in any 12 month period.

                  (d) Other Registration. Notwithstanding the provisions of this
Agreement to the contrary, if the Company is not S-3 Eligible after August 1,
2002, as a result of any action or omission by the Company after such date, the
Holder Notice may request any registration requested under Section 2.1(a) be
effected on Form S-1 (or any applicable successor form). Other than the
requirement that registrations requested under Section 2.1(a) be effected on
Form S-3, any such registration effected pursuant to this paragraph shall be
subject to the same agreements regarding restrictions on public sales or
distributions set forth in Section 2.1.

                  (e) Maximum Number of Demand Registrations. The Company shall
be obligated to effect three such demand registrations pursuant to this Section
2.1.

                  (f) Deferral. Notwithstanding the foregoing, if the Company
shall furnish to Holders requesting the filing of a Registration Statement
pursuant to this Section 2.1, a certificate signed by the President or Chief
Executive Officer of the Company stating that, in the good faith judgment of the
Board, it would be materially detrimental to the Company and its stockholders
for such Registration Statement to be filed, then the Company shall have the
right to defer such filing for a period of not more than 90 days after receipt
of the request of the initiating Holders; provided, however, that the Company
may not utilize this right more than once in any 12 month period.

                  (g) Expenses. All Registration Expenses incurred in connection
with any registration pursuant to this Section 2.1, shall be borne by the
Company. Each Holder participating in a registration pursuant to this Section
2.1 shall bear such Holder's proportionate share (based on the total number of
shares sold in such registration other than for the account of the Company) of
all discounts, commissions or other amounts payable to underwriter(s) or brokers
in connection with such offering by the Holders.

         2.2.     PIGGYBACK REGISTRATIONS.

                  (a) Notice by Company. The Company shall notify all Holders of
Registrable Securities in writing (a "Company Registration Notice") at least 15
days prior to filing any Registration Statement under the Securities Act for
purposes of effecting a public offering of securities of the Company (including,
but not limited to, Registration Statements relating to secondary offerings of
securities of the Company, and Registration Statements relating to a Holder

                                       5
<PAGE>

Notice under Section 2.1(a), but excluding Registration Statements relating to
any employee benefit plan or a corporate reorganization) and will afford each
such Holder an opportunity to include in such Registration Statement all or any
part of the Registrable Securities then held by such Holder. Each Holder
desiring to include in any such Registration Statement all or any part of the
Registrable Securities held by such Holder shall within 5 Business Days after
receipt of the Company Registration Notice, so notify the Company in writing (a
"Piggyback Notice"), and in such notice shall inform the Company of the number
of Registrable Securities such Holder wishes to include in such Registration
Statement. If a Holder decides not to include all of its Registrable Securities
in any Registration Statement thereafter filed by the Company, such Holder shall
nevertheless continue to have the right to include any Registrable Securities in
any subsequent Registration Statement or Registration Statements as may be filed
by the Company with respect to offerings of its securities, all upon the terms
and conditions set forth herein.

                  (b) Underwriting. If a Registration Statement for which the
Company gives a Company Registration Notice is for an underwritten offering,
then the Company shall so advise the Holders of Registrable Securities in the
Company Registration Notice. In such event, the right of any such Holder's
Registrable Securities to be included in a registration pursuant to this Section
2.2 shall be conditioned upon such Holder's participation in such underwriting
and the inclusion of such Holder's Registrable Securities in the underwriting to
the extent provided herein. All Holders proposing to distribute their
Registrable Securities through such underwriting shall enter into an
underwriting agreement in customary form with the managing underwriter or
underwriters selected for such underwriting. Notwithstanding any other provision
of this Agreement, if the managing underwriter(s) determine(s) in good faith
that marketing factors require a limitation of the number of shares to be
underwritten, then the managing underwriter(s) may exclude shares in the manner
set forth in Section 2.1(b); provided, however, if the Registration Statement
originally proposed to be filed under this Section 2.2 is for a primary offering
for cash by the Company, none of the securities to be offered by the Company
shall be excluded. If any Holder disapproves of the terms of any such
underwriting, such Holder may elect to withdraw therefrom by written notice to
the Company and the underwriter(s), delivered at least ten Business Days prior
to the effective date of the Registration Statement. Any Registrable Securities
excluded or withdrawn from such underwriting shall be excluded and withdrawn
from the registration.

                  (c) Withdrawal Right. Notwithstanding any provision contained
in this Section 2.2 to the contrary, the Company shall have the right to
terminate or withdraw any Registration Statement initiated by it (other than in
response to a Holder Notice under Section 2.1) prior to the effectiveness of
such Registration Statement whether or not any Holder has elected to include his
Registrable Securities in such Registration Statement.

                  (d)  Expenses. All Registration Expenses incurred in
connection with any registration pursuant to this Section 2.2, shall be borne by
the Company. Each Holder participating in a registration pursuant to this
Section 2.2 shall bear such Holder's proportionate share (based on the total
number of shares sold in such registration other than for the account of the
Company) of all discounts, commissions or other amounts payable to
underwriter(s) or broker(s) in connection with such offering by the Holders.

                  (e) Not Demand Registration. Registration pursuant to this
Section 2.2 shall not be deemed to be a demand registration as described in
Section 2.1 above. There shall be no limit on the number of times the Holders
may request registration of Registrable Securities under this Section 2.2.

                  (f) Shelf Registrations. In the event the registration
pursuant to this Section 2.2 is a Shelf Registration, the Holders requesting
inclusion in such registration pursuant to Section 2.2(a) shall comply with the
provisions of Section 2.1(c).

         2.3. OBLIGATIONS OF THE COMPANY. Whenever required to effect the
registration of any Registrable Securities under this Agreement the Company
shall, as expeditiously as reasonably possible:

                  (a) Registration Statement. Prepare and file with the SEC a
Registration Statement with respect to such Registrable Securities and use its
commercially reasonable efforts to cause such Registration Statement to become
effective and to keep such Registration Statement effective until the last to
occur of (i) the sale or other distribution of all of the Registrable Securities
covered by such Registration Statement in accordance with the intended methods
of distribution thereof, (ii) the expiration of all periods during which
transactions in Registrable Securities by a dealer are not exempt from the
provisions of Section 5 of the Securities Act by virtue of Section 4(3) of the
Securities Act or during which any dealer is obligated under the Securities Act
to deliver a prospectus in connection with transactions involving Registrable
Securities, (iii) the expiration of all other periods, if any, during which the
Registration Statement is required to remain effective in order to avoid a
violation of applicable law by any Holder or the Company related to the sale or
other distribution of all of the Registrable Securities covered by such
Registration Statement in accordance with the intended methods of distribution
thereof, (iv) in the case of a Shelf Registration, the expiration of the period
requested under Section 2.1(c); provided however that nothing in clauses (i)
through (iii) hereof shall require the Company to keep a Registration Statement
effective for more than 120 days; provided further, that the Holders may request
that the Company grant extensions to such 120-day period and the Company shall
not unreasonably deny such request.

                  (b) Amendments and Supplements. Prepare and file with the SEC
such amendments and supplements to such Registration Statement and the
prospectus used in connection with such Registration Statement as may be
necessary to comply with the provisions of the Securities Act with respect to
the disposition of all securities covered by such Registration Statement.

                  (c) Prospectuses. Furnish to the Holders such number of copies
of a prospectus, including a preliminary prospectus, in conformity with the
requirements of the Securities Act, and such other documents as they may
reasonably request in order to facilitate the disposition of the Registrable
Securities owned by them that are included in such registration.

                  (d) Blue Sky. Use its commercially reasonable efforts to
register and qualify the securities covered by such Registration Statement under
such other securities or "blue sky" laws of

                                       7
<PAGE>

such jurisdictions as shall be reasonably requested by the Holders, provided
that the Company shall not be required in connection therewith or as a condition
thereto to qualify to do business or to file a general consent to service of
process in any such states or jurisdictions.

                  (e) Customary Agreements. Enter into customary agreements
(including, in the case of an underwritten offering, an underwriting agreement
in customary form); make such representations and warranties to any
underwriters, brokers, dealers, placement agents and other Persons involved in
the distribution to any underwriters, brokers, dealers, placement agents and
other persons involved in the distribution of the Registrable Shares included in
such Registration Statement as in form, substance and scope are customarily made
by issuers in similar circumstances or which may be reasonably requested. Each
Holder participating in such underwriting shall also enter into and perform its
obligations under such an agreement.

                  (f) Notification. Notify each Holder of Registrable Securities
covered by such Registration Statement at any time when a prospectus relating
thereto is required to be delivered under the Securities Act of the happening of
any event as a result of which the prospectus included in such Registration
Statement, as then in effect, includes an untrue statement of a material fact or
omits to state a material fact required to be stated therein or necessary to
make the statements therein not misleading in the light of the circumstances
then existing. In addition, the Company shall promptly notify each Holder and
each underwriter, broker, dealer and placement agent participating in any
offering or sale or other distribution of securities covered by such
Registration Statement of the issuance or threatened issuance of any order
suspending the registration or qualification of any Registrable Securities
covered by such Registration Statement for disposition in any jurisdiction; use
its commercially reasonable efforts to prevent the issuance of any such
threatened order and, if any such order is issued, use its commercially
reasonable efforts to obtain the lifting or withdrawal of such order at the
earliest possible moment and promptly notify each Holder and each such
underwriter, broker, dealer and placement agent of any lifting or withdrawal.

                  (g) Opinion and Comfort Letter. Furnish, at the request of any
Holder requesting registration of Registrable Securities, on the date that such
Registrable Securities are delivered to the underwriter(s) for sale, if such
securities are being sold through underwriters, or, if such securities are not
being sold through underwriters, on the date that the Registration Statement
with respect to such securities becomes effective,

                           (i) an opinion, dated as of such date, of the counsel
representing the Company for the purposes of such registration, addressed to the
Holders requesting registration of Registrable Securities

                                    (A) in the event of any offering other than
an underwritten offering, in form and substance as is customarily given to
underwriters in an underwritten public offering and reasonably satisfactory to a
majority in interest of the Holders requesting registration, and

                                    (B) in the event of an underwritten
offering, in the form given to the underwriters.

                                       8
<PAGE>

                           (ii) in any underwritten offering, a "comfort" letter
dated as of such date, from the independent certified public accountants of the
Company, in form and substance as is customarily given by independent certified
public accountants to underwriters in an underwritten public offering and
reasonably satisfactory to a majority in interest of the Holders requesting
registration, addressed to the underwriters and to the Holders requesting
registration of Registrable Securities.

                  (h) Additional Actions. Take all other actions which are
reasonably necessary or which may be reasonably requested by the majority of
selling Holders or any underwriter, broker, dealer or placement agent
participating in any offering or sale or other distribution of securities
covered by such Registration Statement to effect the registration and
qualification of the Registrable Securities covered by such Registration
Statement and to facilitate the disposition thereof in accordance with the
respective plans of distribution of the selling Holders.

         2.4. FURNISH INFORMATION. It shall be a condition precedent to the
obligations of the Company to take any action pursuant to Sections 2.1 or 2.2
that the selling Holders shall furnish to the Company such information regarding
themselves, the Registrable Securities held by them, and the intended method of
disposition of such securities as shall be reasonably requested by the Company
or otherwise required in order to timely effect the Registration of their
Registrable Securities.

         2.5. INDEMNIFICATION. In the event any Registrable Securities are
included in a Registration Statement under Sections 2.1 or 2.2:

                  (a) By the Company. To the extent permitted by law, the
Company will indemnify and hold harmless each Holder, the partners, officers and
directors of each Holder, any underwriter (as determined in the Securities Act)
for such Holder and each person, if any, who controls such Holder or underwriter
within the meaning of the Securities Act or the Exchange Act), against any
losses, claims, damages, or liabilities (joint or several) to which they may
become subject under the Securities Act, the Exchange Act or other federal or
state law, insofar as such losses, claims, damages, or liabilities (or actions
in respect thereof) arise out of or are based upon any of the following
statements, omissions or violations (collectively a "Violation"):

                           (i) any untrue statement or alleged untrue statement
of a material fact contained in such Registration Statement, including any
preliminary prospectus or final prospectus contained therein or any amendments
or supplements thereto;

                           (ii) the omission or alleged omission to state
therein a material fact required to be stated therein, or necessary to make the
statements therein not misleading; or

                           (iii) any violation or alleged violation by the
Company of the Securities Act, the Exchange Act, any federal or state securities
law or any rule or regulation promulgated under the Securities Act, the Exchange
Act or any federal or state securities law in connection with the offering
covered by such Registration Statement;

                                       9
<PAGE>

and the Company will reimburse each such Holder, partner, officer or director,
underwriter or controlling person for any legal or other expenses reasonably
incurred by them, as incurred, in connection with investigating or defending any
such loss, claim, damage, liability or action; provided, however, that the
indemnity agreement contained in this Section 2.5(a) shall not apply to amounts
paid in settlement of any such loss, claim, damage, liability or action if such
settlement is effected without the consent of the Company (which consent shall
not be unreasonably withheld), nor shall the Company be liable in any such case
for any such loss, claim, damage, liability or action to the extent that it
arises out of or is based upon a Violation which occurs in reliance upon and in
conformity with written information furnished expressly for use in connection
with such registration by a Holder, partner, officer, director, underwriter or
controlling person of such Holder.

                  (b) By Selling Holders. To the extent permitted by law, each
selling Holder will indemnify and hold harmless the Company, each of its
directors, each of its officers who have signed the Registration Statement, each
person, if any, who controls the Company within the meaning of the Securities
Act, any underwriter and any other Holder selling securities under such
Registration Statement or any of such other Holder's partners, directors or
officers or any person who controls such Holder within the meaning of the
Securities Act or the Exchange Act, against any losses, claims, damages or
liabilities (joint or several) to which the Company or any such director,
officer, controlling person, underwriter or other such Holder, partner or
director, officer or controlling person of such other Holder may become subject
under the Securities Act, the Exchange Act or other federal or state law,
insofar as such losses, claims, damages or liabilities (or actions in respect
thereto) arise out of or are based upon any Violation, in each case to the
extent (and only to the extent) that such Violation occurs in reliance upon and
in conformity with written information furnished by such selling Holder
expressly for use in connection with such registration; and each such Holder
will reimburse any legal or other expenses reasonably incurred by the Company or
any such director, officer, controlling person, underwriter or other Holder,
partner, officer, director or controlling person of such other Holder in
connection with investigating or defending any such loss, claim, damage,
liability or action: provided, however, that the indemnity agreement contained
in this Section 2.5(b) shall not apply to amounts paid in settlement of any such
loss, claim, damage, liability or action if such settlement is effected without
the consent of the Holder, which consent shall not be unreasonably withheld; and
provided, further, that the total amounts payable in indemnity by a Holder under
this Section 2.5(b) in respect of any Violation shall not exceed the net
proceeds received by such Holder in the registered offering out of which such
Violation arises.

                  (c) Notice. Promptly after receipt by an indemnified party
under this Section 2.5 of notice of the commencement of any action (including
any governmental action), such indemnified party will, if a claim in respect
thereof is to be made against any indemnifying party under this Section 2.5,
deliver to the indemnifying party a written notice of the commencement thereof
and the indemnifying party shall have the right to participate in, and, to the
extent the indemnifying party so desires, jointly with any other indemnifying
party similarly noticed, to assume the defense thereof with counsel mutually
satisfactory to the indemnified and indemnifying parties; provided, however,
that an indemnified party shall have the right to retain its own counsel, with
the fees and expenses to be paid by the indemnifying party, if representation of
such indemnified party by the counsel retained by the indemnifying party would
be inappropriate due to actual or potential conflict of

                                       10
<PAGE>

interests between such indemnified party and any other party represented by such
counsel in such proceeding. The failure to deliver written notice to the
indemnifying party within a reasonable time of the commencement of any such
action shall relieve such indemnifying party of liability to the indemnified
party under this Section 2.5 to the extent the indemnifying party is prejudiced
as a result thereof, but the omission so to deliver written notice to the
indemnified party will not relieve it of any liability that it may have to any
indemnified party otherwise than under this Section 2.5.

                  (d) Defect Eliminated in Final Prospectus. The foregoing
indemnity agreements of the Company and Holders are subject to the condition
that, insofar as they relate to any Violation made in a preliminary prospectus
but eliminated or remedied in the amended prospectus on file with the SEC at the
time the Registration Statement in question becomes effective or in the amended
prospectus filed with the SEC pursuant to SEC Rule 424(b) (the "Final
Prospectus"), such indemnity agreement shall not inure to the benefit of any
person if a copy of the Final Prospectus was timely furnished to the indemnified
party, was not furnished to the person asserting the loss, liability, claim or
damage at or prior to the time such action is required by the Securities Act,
and the furnishing of such Final Prospectus as so required would have eliminated
liabilities under the Securities Act or the Exchange Act.

                  (e) Contribution. In order to provide for just and equitable
contribution to joint liability under the Securities Act in any case in which
either (i) any Holder exercising rights under this Agreement, or any controlling
person of any such Holder, makes a claim for indemnification pursuant to this
Section 2.5, but it is judicially determined (by the entry of a final judgment
or decree by a court of competent jurisdiction and the expiration of time to
appeal or the denial of the last right of appeal) that such indemnification may
not be enforced in such case notwithstanding the fact that this Section 2.5
provides for indemnification in such case, or (ii) contribution under the
Securities Act may be required on the part of any such selling Holder or any
such controlling person in circumstances for which indemnification is provided
under this Section 2.5; then, and in each such case, the Company and such Holder
will contribute to the aggregate losses, claims, damages or liabilities to which
they may be subject (after contribution from others) in such proportion as is
appropriate to reflect not only the relative benefits received by the Company on
the one hand and the selling Holders on the other hand, from the offering of the
Registered Securities, but also the relative fault of the Company and the
selling Holders in connection with the statements or omissions which resulted in
such claim as well as any other relevant equitable considerations; provided,
however, that, in any such case: (A) no such Holder will be required to
contribute any amount in excess of the public offering price of all such
Registrable Securities offered and sold by such Holder pursuant to such
Registration Statement; and (B) no person or entity guilty of fraudulent
misrepresentation (within the meaning of Section 11(f) of the Securities Act)
will be entitled to contribution from any person or entity who was not guilty of
such fraudulent misrepresentation.

                  (f) Survival. The obligations of the Company and Holders under
this Section 2.5 shall survive until 90 days following the third anniversary of
the completion of any offering of Registrable Securities in a Registration
Statement, regardless of the expiration of any statutes of limitation or
extensions of such statutes.

                                       11
<PAGE>

         2.6. TERMINATION OF THE COMPANY'S OBLIGATIONS. The Company shall have
no obligations pursuant to Sections 2.1 and 2.2 with respect to any Registrable
Securities proposed to be sold by a Holder in a registration pursuant to Section
2.1 or 2.2 if, in the opinion of counsel to the Company, all such Registrable
Securities proposed to be sold by a Holder may then be sold under (a) Rule 144
in a single transaction without exceeding the applicable volume limitations
thereunder, or (b) under Rule 144(k).

         2.7. NO REGISTRATION RIGHTS TO THIRD PARTIES. Without the prior written
consent of the Holders of a majority of the Registrable Securities, the Company
covenants and agrees that it shall not grant, or cause or permit to be created,
for the benefit of any person or entity any registration rights of any kind
(whether similar to the demand or "piggyback" registration rights described in
this Section 2, or otherwise) relating to shares of the Company's Common Stock
or any other voting securities of the Company, other than rights that are on a
parity with or subordinate in right to the Holders.

         2.8. RULE 144 REPORTING; S-3 ELIGIBILITY. With a view to making
available the benefits of certain rules and regulations of the Commission which
may at any time permit the sale of "Restricted Securities" (used herein as
defined in Rule 144 under the Securities Act) to the public without
registration, and to be eligible to use Form S-3, the Company agrees to:

                  (a) make and keep public information available, as those terms
are understood and defined in Rule 144 under the Securities Act, at all times
during which the Company is subject to the reporting requirements of the
Exchange Act;

                  (b) file with the Commission in a timely manner all reports
and other documents required of the Company under the Securities Act and the
Exchange Act (at all times during which the Company is subject to such reporting
requirements); and

                  (c) so long as any holders of Registrable Securities owns any
Restricted Securities, to furnish to such holder forthwith upon request a
written statement by the Company as to its compliance with the reporting
requirements of said Rule 144 and with regard to the Securities Act and the
Exchange Act (at all times during which the Company is subject to such reporting
requirements), a copy of the most recent annual or quarterly report of the
Company, and such other reports and documents of the Company and other
information in the possession of or reasonably obtainable by the Company as such
holder of the Registrable Securities may reasonably request in availing itself
of any rule or regulation of the Commission allowing such holder to sell any
such securities without registration.

         2.9. MAINTENANCE OF LISTED STATUS. The Company shall use its
commercially reasonable efforts to maintain its status as a listed company on
the National Market System of the Nasdaq Stock Market, Inc. as such listing
exists as of the date hereof. In the event the Company should be de-listed, for
whatever reason, the Company agrees to use its commercially reasonable efforts
to regain its status as a listed company on the National Market System of the
Nasdaq Stock Market, Inc., or, if not available, the Small Cap Market.

3.       Miscellaneous.

         3.1. GOVERNING LAW. This Agreement shall be governed in all respects by
the laws of the State of Delaware without regard to provisions regarding choice
of laws.

         3.2. SUCCESSORS AND ASSIGNS. Except as otherwise expressly provided
herein, the provisions hereof shall inure to the benefit of, and be binding

amendments. This Agreement and the rights and obligations therein may not be
assigned by a Holder without the written consent of the Company. Notwithstanding
the foregoing, a Holder may transfer its rights hereunder in connection with a

Holder, or to another partnership managed by First Reserve Corporation, (ii) to
the limited or general partners of a Holder in connection with the full or
partial liquidation of such Holder or (iii) to a person who acquires Registrable
Securities having a fair market value of at least $2,500,000 from a Holder in a
private transaction. This Agreement and the rights and obligations therein may
not be assigned by the Company without the written consent of the Holders of a
majority of the Registrable Securities.

         3.3. ENTIRE AGREEMENT; MERGER. This Agreement constitutes the entire
understanding and agreement between the parties with regard to the subjects
hereof and thereof. This Agreement supersedes in their entirety any prior
agreements or understandings between the Holders, on the one hand, and the
Company, on the other hand, regarding the registration of Company securities,
including without limitation the registration rights agreements between St.
James and the Company, dated June 16, 2000, June 29, 2000 and June 30, 2000.

         3.4. NOTICES. Except as may be otherwise provided herein, all notices,

power or remedy accruing to the Company or to the Holders, upon any breach or
default of any party hereto under this Agreement, shall impair any such right,
power or remedy of the Company, or the Holders nor shall it be construed to be a

similar breach of default thereafter occurring; nor shall any waiver of any
other breach or default theretofore or thereafter occurring. Any waiver, permit,
consent or approval of any kind or character on the part of the Company or the
