SUBSCRIPTION AGREEMENT

AND INVESTMENT LETTER



March
, 2003



To the
Board of Directors

Ratexchange Corporation

100 Pine Street, Suite 500

San Francisco, CA 94111



RE: Subscription
to Purchase Units of Ratexchange Corporation



Gentlemen:



This will acknowledge that the undersigned hereby agrees to irrevocably purchase from
Ratexchange Corporation (the Company or RTX),  unit(s) (collectively the Units) at a price of $50,000 per Unit. RTX is a corporation
organized under the laws of the State of Delaware in 1987 under the name Venture World, Ltd. In 1999 it changed its name to NetAmerica.com Corporation and on April 24, 2000 it changed its name to Ratexchange Corporation. The Company had no material
operations prior to 1999. The Unit(s) to be purchased by the undersigned is (are) part of a private placement of securities (the Offering) by the Company of a minimum 50 units, which is being made only to accredited investors
as defined herein.



Each Unit will consist of two hundred and fifty thousand
(250,000) shares of Ratexchange Corporation Series B Convertible Preferred stock (collectively the Preferred Stock) and one Class B Warrant to purchase 62,500 shares of Ratexchange Corporation common stock (collectively the
Warrants). Each warrant share of the Companys common stock will have a par value of $0.0001 and each warrant share may be purchased for $0.30 (the Exercise Price). The Warrants will have a term of three years, unless
the closing sale price for the common stock of the Company has closed at or above $0.90 for ten consecutive trading days. At such time the holders will receive 30 days notice upon which to exercise the Warrants prior to termination.



Holders of the Preferred Shares will be entitled to receive a dividend at the rate of three
percent (3%) per annum based on the number of shares of Series B Preferred Stock then held on the last day of each quarter of the Companys fiscal year, beginning on June 30, 2003. The dividend will be paid in cash. Such dividends shall accrue
and accumulate until paid.



Each share of Preferred Stock shall be convertible,
at the option of the holder, at any time after the date of issuance, into an equal number of shares of common stock. However, the Preferred Stock will automatically convert into an equal number of shares of common stock if the closing sale price for
the common stock of the Company has closed at or above $0.60 for ten consecutive trading days.

Investment Letter for Units of

Ratexchange Corporation



For a complete description of the terms of the Warrants please see Exhibit B, appended hereto. For a complete
description of the terms of the Preferred Stock please see the Certificate of Designation of Series B Preferred Stock, appended hereto as Exhibit C.



The Company shall file a registration statement on Form S-3 for the common stock that underlies the Series B Convertible Preferred stock and Class B Warrants
(collectively, the Underlying Shares) with the Securities and Exchange Commission (the Commission) within 90 days of the closing of the financing and use its reasonable best efforts to have such registration statement
declared effective. The Company will also grant the Unit purchasers certain piggyback registration rights with respect to these securities. Should the Company fail to file a registration statement listing the Underlying Shares with the
Commission within 90 days of the closing of the financing, the holder of each Unit shall be entitled to receive a Series B Warrant to purchase a number of shares of the Companys common stock equal to ten (10%) percent of the aggregate number
of Preferred Shares purchased by the holder in this financing, with a term of three years and an exercise price equal to the closing price of the Companys common stock on the American Stock Exchange on the 90thday following the closing of this financing.



Should the Securities and Exchange Commission fail to declare the Companys Form S-3 Registration Statement effective on or before the 180thday after the Closing, the annual dividend rate payable on the Preferred Stock will be increased from 3.00% to 9.00% for the
period of time from the 181stday after Closing until the Companys registration statement is declared
effective. Upon the Securities and Exchange Commission declaring the registration statement effective, the annual dividend rate will return to 3.00%. Dividends will be paid quarterly in cash, regardless of which dividend rate is applied.



For a complete description of the terms of the Registration Rights please see Exhibit
D, appended hereto.



The minimum number of Units that must be sold in order
to make the Offering effective will be 50 Units. All funds received will be held in escrow and will be remitted directly to the Company upon closing of the financing. The Company reserves the right, in its complete discretion, to sell fractions of a
Unit and to sell additional Units if demand is present.



If all of the Units
are sold, the Company will receive gross proceeds of two and one half million dollars ($2,500,000). See the Schedule of Use of Proceeds appended hereto as Exhibit E.



An executed copy of this Subscription Agreement and Investment Letter and the Purchaser Questionnaire appended hereto as Exhibit A
shall be delivered to the Company.



Upon the Companys acceptance
of the Subscription Agreement and Investment Letter, PAYMENT FOR THE UNITS SHALL BE MADE BY CHECK OR ELECTRONIC WIRE TRANSFER PAYABLE IN ACCORDANCE WITH INSTRUCTIONS FROM THE COMPANY and delivered to the Escrow Agent.

Subscription Agreement and

Investment Letter for Units of

Ratexchange Corporation



Each closing of the purchase and sale of the Units following acceptance by the Company of subscriptions, as evidenced
by the Companys execution of the applicable Subscription Agreements, shall take place at the offices of the Company.



Although the Common Stock is listed for trading on the AMEX under the symbol RTX, there is no public market for the Units, Preferred Shares or the Warrants
and it is not anticipated that a public trading market for them will ever develop. In addition, the market for the Common Stock has been limited. The Company intends to file a registration statement with the Commission covering the Underlying
Shares, but no representation is made that the Commission will declare the filing effective. In the event, however, that the registration statement is declared effective, no assurance can be given that the Underlying Shares will be readily tradable.
ACCORDINGLY, THE UNDERSIGNED UNDERSTANDS AND ACKNOWLEDGES THAT, EVEN AFTER THE TERMINATION OF THE RESALE RESTRICTION PERIODS ON THE UNITS, THE UNDERLYING SECURITIES AND THE UNDERLYING SHARES NOTED BELOW, AND/OR THE UNDERLYING SHARES ARE
REGISTERED, HE MAY BE UNABLE TO RESELL THESE SECURITIES FOR A SIGNIFICANT PERIOD OF TIME, IF EVER.



The undersigned acknowledges that the Unit(s), the Preferred Shares and Warrants (the Underlying Securities) he is purchasing, including any Underlying Shares he may receive upon conversion of the
Preferred Shares and/or exercise of the Warrants, have not been registered under the Securities Act or qualified under applicable state securities laws and that the transferability thereof is restricted by the registration provisions of the Act as
well as such state laws. Based upon the representations and agreements being made by him herein, the Units and Underlying Securities are being sold to him pursuant to an exemption from such registration provided by Section 4 (2) of the Act and Rule
506 promulgated thereunder and applicable state securities law qualification exemptions. The undersigned further acknowledges that the basis for these exemptions may not be available if, notwithstanding such representations, he only intends to hold
these securities for a fixed or determinable period in the future, or until the market price rises or falls. The undersigned represents and warrants that he does not have any such intention. The undersigned agrees that the documentation representing
the Underlying Securities to be received by him, as well as the certificates representing any Underlying Shares, will bear a legend indicating that transfer of these securities is restricted by reason of the fact that they have not been so
registered or qualified, and that the Company will place stop-transfer instructions with the transfer agent of its securities with respect to any Underlying Shares registered in the name of the undersigned or beneficially owned by him.



The undersigned represents that he is acquiring the Unit(s) and Underlying Securities, and
will acquire any Underlying Shares, solely for his own account as principal and not as a nominee or agent, for investment purposes only and not with a view to resale or other distribution or fractionalization thereof, or with the intention of
selling, transferring or otherwise disposing of all or any part of such securities for any particular event or circumstance, except selling, transferring or disposing of them upon full compliance with

Investment Letter for Units of

Ratexchange Corporation



all applicable provisions of the Act, the Securities Exchange Act of 1934 (the Exchange Act), the Rules
and Regulations promulgated by the Commission thereunder, and any applicable state securities laws. The undersigned further understands and agrees that (i) these securities may be sold only if they are subsequently registered under the Act and
qualified under any applicable state securities laws or, in the opinion of the Companys counsel, an exemption from such registration and qualification is available; (ii) any routine sales of these securities made in reliance upon Rule 144
promulgated by the Commission under the Act, can be effected only in the amounts set forth in and pursuant to the other terms and conditions, including applicable holding periods, of that Rule; and (iii) the Company is under no obligation to assist
him in complying with any exemption from registration under the Act, or, except as otherwise set forth herein and in the Certificate of Designation of Series B Preferred Stock and Series B Warrant attached hereto as Exhibits, to register the Units,
the Preferred Stock, the Warrants or the Underlying Shares on his behalf.



The
undersigned represents and warrants that he has received (i) a copy of the form of the Warrant appended hereto as Exhibit B; (ii) a copy of the form of the Certificate of Designation of Series B Preferred Stock appended hereto as Exhibit
C; (iii) a copy of the Registration Rights Agreement appended hereto as Exhibit D; (iv); a Schedule of the Use of Proceeds of this Offering appended hereto as Exhibit E; (v) a copy of the Companys Form 10-Q for the quarterly
period ended September 30, 2002 appended hereto as Exhibit F; (vi) a copy of the Companys Form 10-K for fiscal year 2002 (contained in the 2002 Annual Report) appended hereto as Exhibit G; (vii) a copy of the Companys Proxy
Statement for the Year 2002 Annual Meeting of Stockholders appended hereto as Exhibit H; (viii) a copy of the Companys fully diluted Capitalization Table appended hereto as Exhibit I;and (ix) a Description of Risk Factors
relating to the Company and this Offering appended hereto as Exhibit J; (all of the foregoing documents and the Subscription Agreement collectively are herein referred to as the Information Documents) and that he has read and
understood all of these documents. In addition, the undersigned is aware that the Company files annual, quarterly and special reports, proxy statements and other information with the Commission and he can access these filings on the
Commissions Internet site, which is http://www.sec.gov.

undersigned acknowledges that he has been granted a reasonable time prior to the date hereof, during which he has had the opportunity to obtain such additional information, as he deemed necessary to permit him to make an informed decision with
respect to the purchase of his Unit(s). He also represents and warrants that he (i) has reviewed such other documents and obtained such other information from the Company as he deems necessary in order for him to make an informed investment
decision; (ii) has had access to all relevant documents, instruments, books, and other records of or pertaining to the Company and has had the opportunity to ask questions of and receive answers from management and other representatives of the

were made to him to purchase the Unit(s) and in subscribing for the Unit(s) he is not relying upon any
representations other than those contained herein or in the other Information Documents.



The undersigned understands that this Subscription Agreement and Investment Letter and the other Information Documents, contain forward-looking statements within the meaning of the Private Securities
Litigation Reform Act of 1995, including without limitation, statements regarding future cash requirements, sales forecasts, and profit and loss, cash flow and balance sheet projections. Such forward-looking statements involve known and unknown
risks, uncertainties and other factors which may cause the actual results, performance and achievements of the Company, or industry results, to be materially different from any future results, performance, or achievements expressed or implied by

and retain significant customers, changes in business strategy or development plans, quality of management, availability, terms and deployment of capital, business abilities and judgment of personnel, availability of qualified personnel, changes in,
or the failure to comply with, government regulations, and other factors referenced herein and in the other Information Documents.



THE UNDERSIGNED UNDERSTANDS THAT, BECAUSE OF THE SIGNIFICANT RISK FACTORS SET FORTH HEREIN OR IN THE OTHER INFORMATION DOCUMENTS, INCLUDING BUT NOT LIMITED TO THE
DESCRIPTION OF RISK FACTORS, IF THE OFFERING IS CONSUMMATED, HE COULD LOSE HIS ENTIRE INVESTMENT.



The undersigned also understands that the Company is a securities broker-dealer and investment bank focused on emerging growth companies and growth-oriented institutional investors. It provides sales and trading

On November 20, 2002, the Company and Forsythe McArthur Associates Inc. (FMA)
entered into an agreement wherein the Company purchased an option to restructure the terms of the Convertible Promissory Note held by FMA and dated September 1, 2001 (See Exhibit 10-33, attached to the Companys Annual Report on Form 10K, filed
March 28, 2002, SEC file no. 02592121.) The Company and FMA agreed to the following terms: 1. FMA currently holds a Convertible Promissory Note with principal sum of $5,949,042 and accruing interest at a rate equal to 9.0% per annum. The interest on
the Convertible Promissory Note is payable quarterly, 2. The Company will pay interest on the Convertible Promissory Note for the fourth quarter of year 2002. The Company will not accrue or pay additional interest on the Convertible Promissory Note
for the period

Subscription Agreement and

Investment Letter for Units of

Ratexchange Corporation



from January 1, 2003 through June 30, 2003, as described further below, 3. The Company will purchase an option from
FMA in exchange for 500,000 shares of the Companys common stock and registration rights on those shares (the Option). The Option will have a term beginning on November 20, 2002 and ending on June 30, 2003. Upon the Companys
exercise of the Option, the Convertible Promissory Note will be cancelled and FMA will receive the following restructured consideration in full and complete satisfaction of all obligations owed to it by the Company: a. $500,000 in cash; b. 2,000,000
shares of the Companys common stock, including demand registration rights; and c. a new Promissory Note of principal sum equal to $1,000,000 bearing interest at 3.5% per annum payable quarterly in cash, maturing on December 31, 2005, 4. The
2,000,000 shares of the Companys common stock will include a registration rights agreement wherein FMA will receive both piggyback and demand rights. The Company will file the appropriate registration statement with the Securities and Exchange
Commission on or before June 30, 2003. The registration statement will include the 500,000 shares granted to FMA for the Option and the interest shares earned by FMA under the Restructure Agreement of October 4, 2001. The 2,000,000 shares included
in the restructure consideration will be registered for resale if the Company exercises the Option, 5. Beginning on January 1, 2003 and ending on June 30, 2003, the Company will pay quarterly interest in cash to FMA based upon the terms of the new
Promissory Note, i.e. 3.5% per annum against the principal sum of $1,000,000. Should the Company exercise the Option, no interest will be due or payable under the Convertible Promissory Note subsequent to December 31, 2002 and the restructure terms
set forth in Point 3, will apply and continue through maturity of the new Promissory Note. The Company may pre-pay its obligation under the new Promissory Note at anytime prior to maturity without penalty. Should the Company not exercise the Option;
the amount of interest paid to FMA during the Option Period will be credited against interest payments owed under the Convertible Promissory Note that will be paid on June 30, 2003.



RTX is authorized to issue 300 million shares of Common Stock. Of this amount, 23,067,546 shares are issued and outstanding as of March 6,
2003. Holders of Common Stock are entitled to receive dividends when, as and if declared by the Board of Directors out of funds legally available therefor. They have no preemptive or other rights to subscribe for additional shares and the Common
Stock has no redemption, sinking fund or conversion provisions. Each share of Common Stock is entitled to one vote on any matter submitted to the holders thereof and to equal rights in the assets of the Company upon liquidation subject to the prior
rights of creditors and holders of any preferred stock. The outstanding shares of Common Stock are validly issued, fully paid and non-assessable.



The shares of Common Stock have non-cumulative voting rights, which means that the holders of more than 50% of the shares voting for the election of directors can elect
all of the Directors of the Company. In such event, the holders of the remaining shares will not be able to elect any of the Directors. After the completion of this Offering but before the conversion of any Notes or exercise of any Warrants, the
Companys Directors and executive officers together with their affiliates, will own or control an aggregate of approximately 25% of the then outstanding Common Stock.

Subscription Agreement and

Ratexchange Corporation



RTX has reserved an aggregate of 5 million shares of Common Stock for issuance to directors, officers and other key
employees in the form of incentive or nonqualified stock options, stock appreciation rights, or restricted stock awards pursuant to its Ratexchange Corporation 2001 Stock Option and Incentive Plan (the Plan). Additionally, there are
currently 13 million outstanding options to purchase Common Stock, most of which are exercisable. The exercise prices range from $0.34 per share to $7.00 per share.



The Company is authorized to issue 60 million shares of preferred stock, par value $0.0001 per share, (the Preferred Stock) of
which 599,999 shares of non-redeemable Series A Convertible Preferred Stock (the Series A) are currently issued and outstanding. The Series A is convertible into Common Stock at the ratio of 1:1. Holders of the Series A are entitled to
(i) dividends in kind at the rate of 6% per annum; (ii) a liquidation preference equal to $2.75 per share; (iii) one vote for each share of Common Stock into which the Series A is convertible; and (iv) nominate two directors as long as no less than
600,000 shares of Series A stock is outstanding.



For a complete description of
the Companys capitalization please see the Capitalization Table appended hereto as Exhibit I.



The Companys amended certificate of incorporation authorizes the Board of Directors, without any vote or action by the holders of the Common Stock, to issue Preferred Stock from time to time in one or more
series. The Board is authorized to determine the number of shares and to fix the powers, designations, preferences and relative, participating, optional or other special rights of any series of Preferred Stock. Issuances of Preferred Stock, if
convertible into Common Stock, would be subject to the applicable rules of the AMEX or other markets in which the Common Stock is then quoted or listed for trading. Depending on the terms established by the Board, any or all series of Preferred
Stock could have preference over the Common Stock with respect to dividends and other distributions and upon the liquidation of the Company as well as other matters.



If the Company issues any shares of Preferred Stock with voting powers, or it issues additional shares of Common Stock, the voting power of
the currently outstanding Common Stock would be diluted.



The Delaware General
Corporation Law may subject the Company to certain provisions which, subject to certain exceptions, require that, any business combination of the Company with a 15% or greater stockholder (an Interested Stockholder) or an affiliate
thereof is prohibited for a period of three years following the time that such stockholder became an Interested Stockholder, unless at or subsequent to such time the business combination is approved by the board of directors and authorized at an
annual or special meeting of stockholders, and not by written consent, by the affirmative vote of at least 662/3% of the outstanding voting stock which is not owned by the Interested Stockholder. These provisions could delay or frustrate the removal of incumbent directors or a change in control of the Company. The undersigned understands that
the foregoing provisions could also discourage or make more difficult a merger or other type of corporate reorganization, whether or not management favors such transactions, even if it could be favorable to the interests of the stockholders.

CLASS B WARRANT TO PURCHASE COMMON STOCK



Shares of Common Stock



Issued this 24th day of April 2003.



FOR VALUE RECEIVED, RATEXCHANGE CORPORATION, a corporation organized and existing under the laws of the State of Delaware (the
Company), promises to issue in the name of, and sell and deliver to , or its
registered assigns (in each case, the Holder), a certificate or certificates for an aggregate of
                        
(                ) shares (the B Warrant Shares) of common stock, $0.0001 par value per share (Common Stock), upon compliance with the
terms of this Class B Warrant (B Warrant Agreement.)



|1. |  | Grant of Warrants.
|-- |  | ------------------



The Company hereby grants to the Holder the right to purchase                         
(                )shares of Common Stock for a price equal to $0.30 per share (the Exercise Price). This B Warrant Agreement may be exercised, except
as otherwise provided herein, in whole or in part at any time commencing upon the date of issuance and terminating at 5:00 P.M., New York time, on April 24, 2006, unless the closing sale price for the common stock of the Company has closed at or
above $0.90 for ten consecutive trading days. At such time the Holder will receive 30 days notice upon which to exercise the warrant prior to its expiration. (the Expiration Date)

to



|2. |  | Manner of Exercise.
|-- |  | -------------------



This B Warrant Agreement may be exercised in whole or in part by its surrender, with the form of subscription at the end hereof duly executed by the Holder, to the Company at its principal office or at the office of
its stock transfer agent, accompanied by payment in full in cash or by certified or official bank check to the order of the Company of the Exercise Price of the shares to be purchased. As soon as practicable, but in no event more than 15 days after
the Holder has given the aforesaid written notice and made the aforesaid payment, the Company shall, without charging stock issue or transfer taxes to the Holder, issue or caused to be issued the number of shares of duly authorized Common Stock
issuable upon such exercise, which shall be duly issued, fully paid and non-assessable, and shall deliver to the Holder a certificate or certificates therefor, registered in the Holders name. In the event of a partial exercise of this B
Warrant Agreement, the Company shall also issue and deliver to the Holder a new B Warrant Agreement of like tenor, in the name of the Holder, for the exercise of the number of B Warrant Shares for which such B Warrant Agreement may still be
exercised.



|3. |  | Investment Representation.
|-- |  | --------------------------



The Holder acknowledges that this B Warrant Agreement, as well as, the B Warrant Shares for which this B Warrant Agreement may be exercised, have not been and, except as
otherwise provided herein, will not be registered under the Securities Act of 1933 (the Act) or qualified under applicable state securities laws and that the transferability thereof is restricted by the registration provisions of the Act
as well as such state laws. The Holder represents that he is acquiring the B Warrant Agreement and will acquire the B Warrant Shares for his own account, for investment purposes only and not with a view to resale or other distribution thereof, nor
with the intention of selling, transferring or otherwise disposing of all or any part of such securities for any particular event or circumstance, except selling, transferring or disposing of them upon full compliance with all applicable provisions
of the Act, the Securities Exchange Act of 1934 (the Exchange Act), the Rules and Regulations promulgated by the Securities and Exchange Commission (the Commission) thereunder, and any applicable state securities laws. The
Holder further understands and agrees that (i) neither the B Warrant Agreement nor the B Warrant Shares may be sold unless they are subsequently registered under the Act and qualified under any applicable state securities laws or, in the opinion of
the Companys counsel, an exemption from such registration and qualification is available; (ii) any routine sales of the Companys securities made in reliance upon Rule 144 promulgated by the Commission under the Act, can be effected only
in the amounts set forth in and pursuant to the other terms and conditions, including applicable holding periods, of that Rule; and (iii) except as otherwise set forth herein, the Company is under no obligation to register the B Warrant Agreement or
the B Warrant Shares on his behalf or to assist him in complying with any exemption from registration under the Act. The Holder agrees that each certificate representing any B Warrant Shares for which the B Warrant Agreement may be exercised will
bear on its face a legend in substantially the following form:



These securities have not been registered under the Securities Act of 1933 or qualified under any state securities laws. They may not be sold, hypothecated or otherwise transferred in the absence of an effective registration statement
under that Act or qualification under applicable state securities laws without an opinion acceptable to counsel to the Company that such registration and qualification are not required.

|4. |  | Holder Not Deemed Stockholder.
|-- |  | ------------------------------



The Holder shall not, as holder of the B Warrant Agreement, be entitled to vote or to receive dividends, except as may be provided in Section5 below, or be
deemed the holder of Common Stock that may at any time be issuable upon exercise of the B Warrant Agreement for any purpose whatsoever, nor shall anything contained herein be construed to confer upon the Holder, as holder of the B Warrant Agreement,
any of the rights of a stockholder of the Company or any right to vote for the election of directors or upon any matter submitted to stockholders at any meeting thereof, or to give or withhold consent to any corporate action (whether upon any
recapitalization, issue or reclassification of stock, change of par value or change of stock to no par value, consolidation, merger or conveyance or otherwise), or to receive notice of meetings, or to receive dividends or subscription rights, until
the Holder shall have exercised the B Warrant Agreement and been issued shares of Common Stock in accordance with the provisions hereof.



|5. |  | Warrant Adjustments.
|-- |  | --------------------



The Exercise Price and the number of shares purchasable upon exercise of the B Warrant Agreement shall be subject to adjustment with respect to events after the date hereof as follows:



(a) Subdivision or Combination of Shares. If the
Company is recapitalized through the subdivision or combination of its outstanding shares of Common Stock into a larger or smaller number of shares, the number of B Warrant Shares shall be increased or reduced, as of the record date for such
recapitalization, in the same proportion as the increase or decrease in the outstanding shares of Common Stock, and the Exercise Price shall be adjusted so that the aggregate amount payable for the purchase of all of the B Warrant Shares issuable
hereunder immediately after the record date for such recapitalization shall equal the aggregate amount so payable immediately before such record date.



(b) Dividends in Common Stock or Securities Convertible into Common Stock. If the Company declares a dividend or distribution on
Common Stock payable in Common Stock or securities convertible into Common Stock, the number of shares of Common Stock for which this B Warrant Agreement may be exercised shall be increased, as of the record date for determining which



Page 3 of 9



---

issued by Ratexchange Corporation

to



holders of Common Stock shall be entitled to receive such dividend, in proportion to the increase in
the number of outstanding shares (and shares of Common Stock issuable upon conversion of all such securities convertible into Common Stock) of Common Stock as a result of such dividend or distribution, and the Exercise Price shall be adjusted so
that the aggregate amount payable for the purchase of all the B Warrant Shares issuable hereunder immediately after the record date for such dividend or distribution shall equal the aggregate amount so payable immediately before such record date.



(c) Notice of Adjustment. Whenever the
number of B Warrant Shares purchasable upon the exercise of the B Warrant Agreement or the Exercise Price of the B Warrant Shares is adjusted as provided herein, the Company shall mail to the Holder a notice of such adjustment or adjustments,
prepared and signed by the Chief Executive Officer, Chief Financial Officer or Secretary of the Company, which sets forth the number of B Warrant Shares purchasable upon the exercise of the B Warrant Agreement and the Exercise Price of such B
Warrant Shares after such adjustment, a brief statement of the facts requiring such adjustment, and the computation by which such adjustment was made. Upon an adjustment described herein, the Company may elect to issue a new B Warrant Agreement
reflecting such adjustment, and if the Company so elects, the Holder will return this B Warrant Agreement to the Company in exchange for such new B Warrant Agreement.



(d) The provisions of this Section 3 are for the purpose of, and shall be interpreted to the effect that,
upon any exercise of this B Warrant Agreement, the Holder shall be entitled to receive the same amount and kind of securities and other property that it would have been entitled to receive as the owner at all times subsequent to the date hereof of
the number of shares of Common Stock issuable upon conversion of the B Warrant Shares purchased upon any such exercise.



(e) It is agreed and understood that no adjustments shall be made hereunder solely as a result of the issuance by the Company of: (i)
Common Stock issued pursuant to any future public or private issuance of stock; or (ii) Common Stock issued upon the exercise of warrants or options granted by the Company.



(f) No adjustment of the Exercise Price shall be made in an amount of less than 1% of the Exercise Price in
effect at the time such adjustment is otherwise required to be made, but any such lesser adjustment shall be carried forward and shall be made at the time and together with the next subsequent adjustment which, together with any adjustments so
carried forward, shall amount to not less than 1% of such Exercise Price.



(g) Irrespective of any adjustment or change in the Exercise Price, or the number of shares of Common Stock actually purchasable under each B Warrant Agreement of like tenor, the B Warrant Agreement theretofore and
thereafter issued may continue to express the Exercise Price per Share and the number of B Warrant Shares purchasable thereunder as the Exercise Price per Share and the number of B Warrant Shares purchasable were expressed on the B Warrant Agreement
when initially issued.

|6. |  | Fractional Shares.
|-- |  | ------------------



If the number of B Warrant Shares purchasable upon the exercise of the B Warrant Agreement is adjusted pursuant to Section5 hereof, the Company shall nevertheless not be required to issue fractions of
shares upon exercise of the B Warrant Agreement or otherwise, or to distribute certificates that evidence fractional shares. Instead the Company will round any fractional share to the nearest share so that if the fraction is less than 0.5 no share
shall be issued and if the fraction is 0.5 or higher the Company shall issue one full share



|7. |  | Inclusion of B Warrant Shares in Registration Statement; Right to Registration.
|-- |  | -------------------------------------------------------------------------------



(a) Holders Right to Registration. The Company shall file a registration statement on Form S-3 for the common stock
that underlies the Class B Warrant Agreement with the Securities and Exchange Commission (the Commission) within 120 days of the closing of the financing and use its reasonable best efforts to have such registration statement declared
effective. Should the Company fail to file a registration statement listing the Underlying Shares with the Commission within 90 days of the closing of the financing, the Holder shall be entitled to receive an additional B Warrant Agreement to
purchase a number of shares of the Companys common stock equal to ten (10%) percent of the aggregate number of Preferred Shares purchased by the Holder in this financing, with a term of three years, unless the closing sale price for the common
stock of the Company has closed at or above $0.90 for ten consecutive trading days. At such time the Holder will receive 30 days notice upon which to exercise the warrant prior to its expiration. The exercise price shall be equal to the closing
price of the Companys common stock on the American Stock Exchange on the 90thday following the closing of
this financing.



(b) Piggyback Registration Rights.
If at any time after the date hereof, the Company proposes to file a Registration Statement under the Act with respect to any of its securities (except one relating to employee benefit plans or a merger or similar transaction), it shall give written
notice of its intention to effect such filing to the Holder at least 30 days prior to filing such Registration Statement (the Piggyback Registration Statement). If the Holders Registerable Securities have not been previously
registered as provided in Paragraph 7 (a)above, and he desires to include his Registerable Securities in the Piggyback Registration Statement, he shall notify the Company in writing within 15 days after receipt of such notice from the
Company, in which event the Company shall include the Holders Registerable Securities in the Piggyback Registration Statement. If the Holder elects to include his Registerable Securities in the Piggyback Registration Statement as set forth
herein, he shall, in a timely fashion, provide the Company and its counsel with such information and execute such documents as its counsel may reasonably require to prepare and process the Piggyback Registration Statement.

(c) Copies of Registration Statements and Prospectuses. The Company will provide the Holder with a
copy of the Demand Registration Statement or Piggyback Registration Statement, as the case may be, and any amendments thereto, and copies of the final prospectus included therein in such quantities as may reasonably be required to permit the Holder
to sell his Registerable Securities after the Registration Statement or Piggyback Registration Statement, as the case may be, is declared effective by the Commission.



(d) The Companys Obligation to Bear Expenses of Registration. The Company will bear all expenses (except underwriting
discounts and commission, if any, and the legal fees and expenses, if any, of counsel to the Holder) necessary and incidental to the performance of its obligations under this Section7.



(e) Indemnification. The Company and the Holder, if the Holders
Registerable Securities are included in a Registration Statement pursuant to this Section 7, shall provide appropriate cross indemnities to each other covering the information supplied by the indemnifying party for inclusion in such
Registration Statement.

registration in accordance with the requirements of such underwriter.



(g) Cancellation of Registration Rights. Anything to the contrary notwithstanding, the Company shall not be required to register any Registerable Securities that, in the reasonable opinion of the Companys counsel, may be sold pursuant
to the exemption from registration provided by Section (k) of Rule 144 promulgated under the Act.

RATEXCHANGE CORPORATION

SUBSCRIPTION AGREEMENT

AND

INVESTMENT LETTER



Certificate Of Designation

Of Series B Convertible Preferred Stock



Ratexchange Corporation (the Company), organized and existing under the provisions of the General Corporation Law of the State of Delaware, does hereby certify that the Board of Directors of the Company adopted the
following resolution on March 7, 2003:



RESOLVED, that
pursuant to the authority expressly granted to and vested in the Board of Directors of the Company (the Board of Directors) by the provisions of the Certificate of Incorporation of the Company (the Certificate of
Incorporation), there hereby is created, out of the shares of Preferred Stock, par value $0.0001 per share, of the Company authorized in the Certificate of Incorporation (the Preferred Stock), which series shall have the
following powers, designations, preferences and relative, participating, optional or other rights and the following qualifications, limitations and restrictions (in addition to the powers, designations, preferences and relative, participating,
optional or other rights, and the qualifications, limitations and restrictions, set forth in the Certificate of Incorporation which are applicable to the Preferred Stock):



Section 1. Designation and Amount. The shares of such series shall be designated as Series B Convertible
Preferred Stock (the Series B Preferred Stock) and the authorized number of shares constituting such series shall be 12,500,000, based upon the sale of 50 Units. However, the Company may sell additional Units if demand is
present. The par value of the Series B Preferred Stock shall be $0.0001 per share.



Section 2. Dividend Provisions.



a. The holders of shares of Series B Preferred Stock shall be entitled to receive dividends at the rate of three percent (3%) per annum based on the number of shares of Series B Preferred Stock then held on the last day of each quarter of
the Companys fiscal year, beginning on June 30, 2003. The dividend will be paid in cash. Such dividends shall accrue and accumulate until paid.



b. Should the Securities and Exchange Commission fail to declare the Companys Form S-3 Registration Statement effective on or before the
180thday after the Closing, the annual dividend rate payable to the holders on the Series B Preferred Stock will be
increased from 3.00% to 9.00% for the period of time from the 181stday after Closing until the Companys
registration statement is declared effective. Upon the Securities and Exchange Commission declaring the registration statement effective, the annual dividend rate will return to 3.00%. Dividends will be paid quarterly in cash, regardless of which
dividend rate is applied.



---

c. In the instance of Companys failure to pay the holders of the Series B Preferred Stock the
dividend due for two consecutive fiscal quarters, the holders of record of the Series B Preferred Stock shall be entitled to elect two (2) members of the Companys Board of Directors at each annual election of directors, until such time as the
class of Series B Preferred Stockholders hold less than 2,000,000 shares of unconverted Series B Preferred Stock.



Section 3. Redemption. The Series B Preferred Stock is not redeemable.



Section 4. Conversion. The holders of the Series B Preferred Stock shall have conversion rights as follows (the
Conversion Rights):



(a) Right to
Convert. Each share of Series B Preferred Stock shall be convertible, at the option of the holder thereof, at any time after the date of issuance of such share, at the office of this Company or any transfer agent for such stock, into an equal
number of fully paid and nonassessable shares of common stock (the Conversion Ratio).



(b) Automatic Conversion. The Preferred Stock will automatically convert into an equal number of shares of common stock if the closing sale price
for the common stock of the Company has closed at or above $0.60 for ten consecutive trading days.



(c) Mechanics of Conversion. Before any holder of Series B Preferred Stock shall be entitled to convert the same into shares of common stock, under
Section 4(a) or (b) above, he or she shall surrender the certificate or certificates therefor, duly endorsed, at the office of this Company or of any transfer agent for the Series B Preferred Stock, and shall give written notice to the
Company at its principal corporate office of the election to convert the same and shall state therein the name or names in which the certificate or certificates for shares of common stock are to be issued. The Company shall, as soon as practicable
thereafter, issue and deliver at such office to such holder of Series B Preferred Stock, or to the nominee or nominees of such holder, a certificate or certificates for the number of shares of common stock to which such holder shall be entitled as
aforesaid. Such conversion shall be deemed to have been made immediately prior to the close of business on the date of such surrender of the shares of Series B Preferred Stock to be converted, and the person or persons entitled to receive the shares
of common stock issuable upon such conversion shall be treated for all purposes as the record holder or holders of such shares of common stock as of such date.



Section 5 Adjustments of Preferred Stock for Splits, Dividends and Combinations: The number of the Series B Preferred Stock shall be subject to
adjustment from time to time as follows:



(a) Stock Splits
or Dividends. In the event the Company should at any time or from time to time after the execution date of this certificate fix a record date for the effectuation of a split or subdivision of the outstanding shares of common stock or the



- 2 -



---

determination of holders of common stock entitled to receive a dividend or other distribution payable in additional
shares of common stock or other securities or rights convertible into, or entitling the holder thereof to receive directly or indirectly, additional shares of common stock (hereinafter referred to as Common Stock Equivalents)
without payment of any consideration by such holder for the additional shares of common stock or the Common Stock Equivalents (including the additional shares of common stock issuable upon conversion or exercise thereof), then, as of such record
date (or the date of such dividend distribution, split or subdivision if no record date is fixed), the Conversion Ratio of the Series B Preferred Stock shall be appropriately adjusted so that the number of shares of common stock issuable on
conversion of each share of such series shall be adjusted in proportion to such adjustment of the aggregate of shares of common stock outstanding and those issuable with respect to such Common Stock Equivalents.



(b) Combinations. If the number of shares of common stock outstanding
at any time after the execution date of this certificate is decreased by a combination of the outstanding shares of common stock, then, following the record date of such combination, the Conversion Ratio for the Series B Preferred Stock shall be
appropriately adjusted so that the number of shares of common stock issuable on conversion of each share of such series shall be adjusted in proportion to such decrease in outstanding shares.



(c) No Impairment. The Company will not, by amendment of its
Certificate of Incorporation or through any reorganization, recapitalization, transfer of assets, consolidation, merger, dissolution, issue or sale of securities or any other voluntary action, avoid or seek to avoid the observance or performance of
any of the terms to be observed or performed hereunder by the Company, but will at all times in good faith assist in the carrying out of all the provisions of this Section 5 and in the taking of all such action as may be necessary or appropriate in
order to protect the Conversion Rights of the holders of the Series B Preferred Stock against impairment.



(d) No Fractional Shares and Certificate as to Adjustments. No fractional shares shall be issued upon the conversion of any share or shares of the
Series B Preferred Stock, and the number of shares of common stock to be issued shall be determined by rounding to the nearest whole share. Such conversion shall be determined on the basis of the total number of shares of Series B Preferred Stock
the holder is at the time converting into common stock and such rounding shall apply to the number of shares of common stock issuable upon such aggregate conversion.



(e) Notices of Record Date. In the event of any taking by the Company of a record of the holders of any class of
securities for the purpose of determining the holders thereof who are entitled to receive any dividend (other than a cash dividend) or other distribution, any right to subscribe for, purchase or otherwise acquire any shares of stock of any class or
any other securities or property, or to receive any other right, the Company shall mail to each holder of Series B Preferred Stock, at least twenty (20) days prior to the date specified therein, a notice specifying the date on which any such record
is to be taken for the purpose of such dividend, distribution or right, and the amount and character of such dividend, distribution or right.



- 3 -



---

Section 6 Reservation of Stock Issuable Upon Conversion. The Company shall at all times reserve
and keep available out of its authorized but unissued shares of common stock, solely for the purpose of effecting the conversion of the shares of the Series B Preferred Stock and for paying the dividend pursuant to Section 2 hereof, such number of
its shares of common stock as shall from time to time be sufficient to effect the conversion of all outstanding shares of the Series B Preferred Stock and to pay all accumulated dividends.



Section 7. Voting Rights. The holder of each share of Series B
Preferred Stock shall have the right to one vote for each share of common stock into which such share of Series B Preferred Stock could then be converted, and with respect to such vote, such holder shall have full voting rights and powers equal to
the voting rights and powers of the holders of common stock, and shall be entitled, notwithstanding any provision hereof, to notice of any stockholders meeting in accordance with the bylaws of the Company, and shall be entitled to vote,
together with holders of common stock, with respect to any question upon which holders of common stock have the right to vote. Fractional votes shall not; however, be permitted and any fractional voting rights available on an as-converted basis
(after aggregating all shares into which shares of Series B Preferred Stock held by each holder could be converted) shall be rounded to the nearest whole number (with one-half being rounded upward).



Section 8. Status of Converted Stock. In the event any shares of
Series B Preferred Stock shall be converted pursuant to Section 5 hereof, the shares so converted shall be canceled and shall not be issuable by the Company.



This Certificate of Designation has been signed by the Chairman and Chief Executive Officer of the Company on this 3rd day of April 2003.

SUBSCRIPTION AGREEMENT



AND



INVESTMENT LETTER



Registration Rights Agreement



AGREEMENT dated as of April 24, 2003 between Ratexchange Corporation, a Delaware corporation (with its successors and assigns, the Issuer), and each person or entity listed on the signature
pages hereof (each, with its successors, a Subscriber).



WHEREAS, pursuant to the Subscription Agreement and Investment Letter dated April 24, 2003, the Issuer is issuing, on the date hereof, to each of the Subscribers a certain number of shares of the Issuers Series
C Preferred Stock, convertible into the Issuers common stock and a Class B Warrant to purchase shares of the Issuers common stock (the Convertible Securities);



WHEREAS, the Issuer wishes to agree that the Subscribers will have the right
to participate in certain registrations of the Issuers common stock pursuant to the Securities Act of 1933;



NOW, THEREFORE the parties agree as follows:



1. Definitions



1.1 Standard Definitions. The following terms, when capitalized, are used herein with the following meanings:



Covered Shares means the common stock of the
Issuer that is issuable or issued upon conversion or exercise of the Convertible Securities.



Majority Subscribers means Subscribers that own, at the time of determination, in the aggregate, not less than 51% of the total number of Covered Shares then owned by all of the Subscribers.



1933 Act means the Securities Act of
1933 and the rules and regulations issued thereunder, as amended from time to time.



1934 Act means the Securities Exchange Act of 1934 and the rules and regulations issued thereunder, as amended from time to time.



Other Seller of Stock of Issuer means, if a Subscribers Covered Shares are Registered
pursuant to this Agreement, each other holder (not including the Issuer itself) of securities of the Issuer that are sold as part of the same offering of the Issuers securities.



---

To Register any securities means to effect the registration of such securities
by preparing and filing a registration statement or similar document in compliance with the 1933 Act, and the declaration or ordering of effectiveness of such registration statement or document. The words Registered and
Registration have corresponding meanings.



Rule 144 means Rule 144 promulgated by the Securities and Exchange Commission under the 1933 Act and any successor rule to substantially the same effect, in each case as amended from time.



2. Registration Rights



2.1 Mandatory Registration. The Issuer shall file a
registration statement on Form S-3 for the common stock that underlies the Series C Convertible Preferred stock and Class B Warrants (collectively, the Covered Shares) with the Securities and Exchange Commission (the
Commission) within 90 days of the closing of the financing and use its reasonable best efforts to have such registration statement declared effective. The Issuer will also grant the Subscribers certain piggyback registration
rights with respect to these securities. Should the Issuer fail to file a registration statement listing the Covered Shares with the Commission within 90 days of the closing of the financing, the Subscriber shall be entitled to receive a Class B
Warrant to purchase a number of shares of the Issuers common stock equal to ten (10%) percent of the aggregate number of Series C Preferred Shares purchased by the Subscriber in this financing, with a term of three years and an exercise price
equal to the closing price of the Issuers common stock on the American Stock Exchange on the 90thday
following the closing of this financing.



Should the Commission fail to declare
the Issuers Form S-3 Registration Statement effective on or before the 180thday after the Closing, the annual
dividend rate payable on the Series C Preferred Stock will be increased from 3.00% to 9.00% for the period of time from the 181stday after Closing until the Issuers registration statement is declared effective. Upon the Commission declaring the registration statement effective, the annual dividend rate will return to 3.00%. Dividends will be paid
quarterly in cash, regardless of which dividend rate is applied.



2.2 Piggyback Registration. If the Issuer proposes to Register any of its common stock (other than a Registration (a) relating to the sale of securities to employees of the Issuer pursuant to a stock option, stock purchase or
similar plan which is Registered on Form S-8 or otherwise, (b) relating to an exchange offer or offering of securities solely to the Issuers existing security holders, (c) relating to a Rule 145 transaction or (d) on any form which does not
include substantially the same information as would be required to be included in a registration statement covering the sale of Covered Shares owned by the Subscribers), the Issuer shall cause to be Registered all of the Covered Shares of each
Subscriber and (ii) to cause such Covered Shares to be registered and qualified under the securities or Blue Sky laws of such states in which the other shares included in such public offering are generally registered and qualified, provided that
such Subscriber has provided to the Issuer such information regarding itself and the disposition of the Covered Shares as is required to effect such Registration, registration and qualification.



- 2 -



---

2.3 Actions on Registration. Whenever required by this Agreement to effect the Registration
of any Covered Shares, the Issuer will, as expeditiously as reasonably possible, furnish to the Subscribers such number of copies of a prospectus, including a preliminary prospectus, in conformity with the requirements of the 1933 Act, and such
other documents as the Subscribers may reasonably request in order to facilitate the disposition of such shares.



2.4 Expenses of Registration. The Issuer shall bear the costs and expenses of any Registration pursuant to this Agreement, including without
limitation all registration, filing and qualification fees, printers and accounting fees relating thereto.



2.5 Indemnification.



(a) The Issuer agrees to indemnify and hold harmless each Subscriber from and against any and all losses, claims, damages and liabilities (each, a
Loss) under the 1933 Act, the 1934 Act and the state laws of the state or states in which the Issuer registers or qualifies the Covered Shares, and reasonable fees and expenses of counsel in connection therewith, insofar as
such Losses are caused by (i) any untrue statement or alleged untrue statement of a material fact contained in any registration statement or prospectus relating to the Covered Shares (as amended or supplemented if the Issuer shall have furnished any
amendments or supplements thereto), (ii) any 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
Issuer of the 1993 Act, the 1934 Act, the laws of any state in which the Issuer registers or qualifies the Covered Shares, or any rules or regulations promulgated thereunder, provided that no Subscriber is entitled to indemnification under
this Section for any Loss:



(i) arising from
any untrue statement or omission or alleged untrue statement or omission based upon written information furnished to the Issuer by or on behalf of such Subscriber expressly for use in connection with such registration;



(ii) arising in connection with any preliminary prospectus,
if the person or entity asserting any such Loss was not provided with a current copy of the prospectus and such current copy of the prospectus would have cured the defect giving rise to such Loss; or



(iii) under any settlement effected without the consent of
the Issuer, which consent shall not unreasonably be withheld.



(b) Each Subscriber severally agrees to indemnify and hold harmless the Issuer, its officers, directors and agents, and each person or entity, if any, who controls the Issuer within the meaning of Section 15 of the 1933 Act or Section 20 of
the 1934 Act, from and against any and all Losses under the 1933 Act, the 1934 Act or applicable state law, and reasonable fees and expenses of counsel in connection therewith, insofar as such Losses are caused by any untrue statement or alleged
untrue statement of a material fact contained in any registration statement or prospectus relating to a distribution of the Issuers common stock in which such Subscriber is a selling Subscriber (as amended or supplemented if the Issuer shall
have furnished any amendments or supplements thereto) or caused by any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, but only to the extent
such untrue statement or omission or alleged untrue statement or omission is based upon information furnished to the Issuer in writing by or on behalf of such Subscriber concerning such Subscriber expressly for use in connection with such
registration.



- 3 -



---

(c) In case any proceeding (including any governmental investigation) shall be instituted involving any
person or entity in respect of which indemnity may be sought pursuant to this Section, such person or entity (an Indemnitee) shall promptly notify each person or entity against whom such indemnity may be sought (an
Indemnitor) in writing and the Indemnitors (all, jointly, or one or more of them, pursuant to an agreement among such Indemnitors) shall assume the defense thereof, including the employment of counsel reasonably
satisfactory to such Indemnitee, and shall assume the payment of all fees and expenses. In any such proceeding, each Indemnitee shall have the right to retain its own counsel, but the fees and expenses of such counsel shall be at the expense of such
Indemnitee. It is understood that no Indemnitor shall, in connection with any proceeding or related proceedings in the same jurisdiction, be liable for the reasonable fees and expenses of more than one separate firm of attorneys (in addition to any
local counsel) at any time for all Indemnitees, and that all such fees and expenses shall be reimbursed as they are incurred. The Indemnitor shall not be liable for any settlement of any proceeding effected without its written consent, but if
settled with such consent, or if there be a final judgment for the plaintiff, the Indemnitor shall indemnify and hold harmless such Indemnitees from and against any loss or liability (to the extent stated above) by reason of such settlement or
judgment.



(d) If the indemnification provided for in this
Section 2.5 is, as a matter of applicable law, unavailable to an Indemnitee on account of any Loss, then each Indemnitor, in lieu of indemnifying such Indemnitee, shall contribute to the amount paid or payable by such Indemnitee on account of such
Loss (and fees and expenses of counsel) in such proportion as is appropriate to reflect the relative fault of the parties in connection with the statements or omissions that resulted in such Loss, as well as any other relevant equitable
considerations. The relative fault of the parties shall be determined by reference to, among other things, whether the untrue or allegedly untrue statement or omission or alleged omission relates to information supplied by the Issuer or a
Subscriber, and the parties relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Issuer and each Subscriber agree that it would not be just and equitable if contribution
pursuant to this paragraph were determined by pro rata allocation or by any other method of allocation that does not take account of the equitable considerations referred to above.



2.6 No Delay of Registration. Each Subscriber hereby irrevocably waives and covenants not to assert any right
such Subscriber might have to obtain or seek an injunction, administrative order or other action restraining or otherwise delaying the Registration of securities of the Issuer in connection with any controversy that may arise with respect to the
interpretation and enforcement of this Agreement.



- 4 -



---

2.7 Rule 144. To the extent necessary to make available to the Subscribers the benefits of
Rule 144, the Issuer will:



(i) make and keep
public information available as required by Rule 144;



(ii) file with the Securities and Exchange Commission in a timely manner all reports and other documents required of the Issuer under the 1934 Act; and



(iii) furnish to any Subscriber upon request (x) a written statement by the Issuer that it has complied with
the reporting requirements of Rule 144, the 1933 Act and the 1934 Act, or that it qualifies as a registrant whose securities may be resold pursuant to Form S-1 or Form S-3; (y) a copy of the most recent annual or quarterly report of the Issuer and
such other reports and documents as the Issuer has filed pursuant to the 1933 Act or the 1934 Act; and (z) such other information as may be reasonably requested by a Subscriber to permit it to sell Covered Shares without the requirement of
Registration, pursuant to Rule 144.



3. Miscellaneous



3.1 Notices. All notices and other
communications hereunder shall be in writing (including facsimile transmission), and shall be given to each party at the address or telecopier number set forth under its name on the signature page hereof, or such other address or telecopier number
as such party may hereafter specify for the purpose by notice to the other. Each such notice or other communication shall be effective (a) if given by mail, 72 hours after such communication is deposited in the mails with first class postage
prepaid, addressed as aforesaid or (b) otherwise, when delivered at the address or received at the telecopier number specified in this Section.



3.2 Amendment; No Waivers; Integration. Any provision of this Agreement may be amended or waived if, and only if, such amendment or waiver
is in writing and signed, in the case of an amendment, by the Issuer and the Majority Subscribers or, in the case of a waiver, by the party against whom the waiver is to be effective (or, in the case of waiver that is to be effective against any
Subscriber, by the Majority Subscribers). This Agreement constitutes the entire agreement among the parties with respect to the subject matter hereof and supersedes all prior agreements, understandings and negotiations, both written and oral, among
any of the parties with respect to the subject matter of this Agreement.



3.3 Assignment.



(a) Except as expressly set forth in this Section 3.3, no party hereto may assign, delegate or otherwise transfer any of its obligations or rights under this Agreement.



(b) A Subscribers rights to cause the Issuer to register Covered Shares pursuant to this Agreement may be assigned
(but only with all related obligations) by a Subscriber to a Qualified Transferee as defined below (who shall thereafter be deemed a Subscriber under this Agreement) if, but only if, all of the following conditions are
satisfied;



- 5 -



---

(i) the Subscriber provides the Issuer with advance written notice of the name and
address of such transferee or assignee and the securities with respect to which such registration rights are being assigned;



(ii) the Subscriber satisfies the Issuer to its reasonable satisfaction that the transfer of Covered Shares to the Qualified Transferee
satisfies all requirements of the 1933 Act and the 1934 Act and the regulations promulgated thereunder, and that there is no legal restriction on the Issuers recording such transfer on the records of the Issuer;



(iii) the Qualified Transferee completes all investor
questionnaires or similar documents reasonably requested by the Issuer with respect to the foregoing;



(iv) the Qualified Transferee agrees in writing to be bound by and subject to the terms and conditions of this Agreement, including

for the benefit of a Subscriber that is a natural person, or (iii) any transferee or assignee who after giving effect to such transfer holds not less than two hundred fifty thousand (250,000) Covered Shares.



3.4 Governing Law; Jurisdiction. This Agreement shall be
governed by and construed in accordance with the laws of the State of California. Each party submits to the nonexclusive jurisdiction of the United States District Court for the Northern District of California and of any California state court
sitting in the City and County of San Francisco for purposes of all legal proceedings arising out of or relating to this Agreement or the transactions contemplated hereby. Each party irrevocably waives any objection that it may now or hereafter have
to the laying of venue in any proceeding brought in such a court, and any claim that any such proceeding was brought in an inconvenient forum.



3.5 Headings. The headings and captions in this Agreement are included for convenience of reference only and shall be ignored in the
