Dear Sir/Madam,

The purpose of this letter agreement is to confirm the terms and conditions of
the transaction entered into between RAMP Series 2006-RS4 Trust acting through
JPMorgan Chase Bank N.A., not in its individual capacity, but solely as Trustee
for the benefit of RAMP Series 2006-RS4 Trust and Bank of America, N.A., a
national banking association organized under the laws of the United States of
America (each a "party" and together "the parties") on the Trade Date specified
below (the "Transaction"). This letter agreement constitutes a "Confirmation" as
referred to in the ISDA Master Agreement specified in paragraph 1 below. In this
Confirmation, "Party A" means Bank of America, N.A., and "Party B" means RAMP
Series 2006-RS4 Trust acting through JPMorgan Chase Bank N.A., not in its

2006-RS4 Trust.

except for the elections noted below) on the Trade Date of the Transaction (such

between the provisions of the Form Master Agreement and this Confirmation, this
Confirmation will prevail for the purpose of this Transaction.

related to the terms and conditions of this Transaction shall not be considered

of the Form Master Agreement, if at any time and so long as one of the parties
to the Form Master Agreement ("X") shall have satisfied in full all its payment
and delivery obligations under Section 2(a)(i) of the Form Master Agreement and
shall at the time have no future payment or delivery obligations, whether
absolute or contingent, under such Section, then unless the other party ("Y") is

delivery: (i) the occurrence of an event described in Section 5(a), excluding
Section 5(a)(vii), of the Form Master Agreement with respect to X shall not

long-term and short-term senior unsecured deposit ratings of Party A cease to be
at least A and A-1 by Standard & Poor's Ratings Service ("S&P") and at least A1

obligations are rated by S&P or Moody's. "Rating Agency Condition" means, with
respect to any action taken or to be taken, a condition that is satisfied when
S&P and Moody's have confirmed in writing that such action would not result in
the downgrade, qualification (if applicable) or withdrawal of the rating then
assigned by such Rating Agency to the applicable class of Certificates.
Notwithstanding the forgoing, in the event the long-term senior unsecured
deposit ratings of Party A ceases to be at least BBB- or is withdrawn by S&P, to

hereunder to another party, subject to satisfaction of the Rating Agency
Condition.

understood and agreed by the parties hereto that (i) this Confirmation is
executed and delivered by JPMorgan Chase Bank N.A. , not individually or
personally but solely as trustee ("Trustee") of Party B, in the exercise of the

liability on Trustee, individually or personally, to perform any covenant either
expressed or implied contained herein, all such liability, if any, being
expressly waived by the parties hereto and by any Person claiming by, through or
under the parties hereto; provided that nothing in this paragraph shall relieve

     (m) Severability. If any term, provision, covenant, or condition of this
Agreement, or the application thereof to any party or circumstance, shall be
held to be invalid or unenforceable (in whole or in part) for any reason, the
remaining terms, provisions, covenants, and conditions hereof shall continue in
full force and effect as if this Agreement had been executed with the invalid or
unenforceable portion eliminated, so long as this Agreement as so modified
continues to express, without material change, the original intentions of the
parties as to the subject matter of this Agreement and the deletion of such
portion of this Agreement will not substantially impair the respective benefits
or expectations of the parties.

     The parties shall endeavor to engage in good faith negotiations to replace
any invalid or unenforceable term, provision, covenant or condition with a valid
or enforceable term, provision, covenant or condition, the economic effect of
which comes as close as possible to that of the invalid or unenforceable term,
provision, covenant or condition.

     (n) Notwithstanding anything to the contrary contained herein, none of
Party B or any of its officers, directors, or shareholders (the "Non-recourse
Parties") shall be personally liable for the payment by or on behalf of RAMP

and Residential Asset Mortgage Products, Inc. ("RAMP") are required under
Regulation AB under the Securities Act of 1933 and the Securities Exchange Act

regarding Party A depending on the applicable "significance percentage" of this
Confirmation, as calculated from time to time in accordance with Item 1115 of
Regulation AB.

     (b) If required, Party A shall provide to RFC or RAMP the applicable
financial information described under Item 1115 of Regulation AB (the "Reg AB

request for such Reg AB Information by RFC or RAMP (the "Response Period"), so
long as RFC or RAMP has reasonably determined, in good faith, that such
information is required under Regulation AB; provided, however that if Party A
in good faith determines that it is unable to provide the Reg AB Information
within the Response Period, then, subject to the Rating Agency Condition, (i)
Party A shall cause a Reg AB Approved Entity (as defined below) to replace Party
A as party to this Confirmation on terms substantially similar to this
Confirmation prior to the expiration of the Response Period, and (ii) such Reg
AB Approved Entity shall provide the Reg AB Information prior to the expiration
of the Response Period. "Reg AB Approved Entity" means any entity that (i) has
the ability to provide the Reg AB Information and (ii) meets or exceeds the
"Approved Rating Thresholds". "Approved Rating Thresholds" shall mean an entity
that has a long-term and short-term senior unsecured deposit rating of at least
A and A-1 by S&P, A1 and P-1 by Moody's or A and F1 by Fitch, to the extent such
obligations are rated by S&P, Moody's and Fitch. If RFC or RAMP requests (in
writing) the Reg AB Information from Party A, then Party B shall cause RFC or
RAMP to promptly (and in any event within three (3) Local Business Days of the
date of the request for the Reg AB

                                       13

Information) provide Party A with a written explanation of how the significance
percentage was calculated.

     (c) Party A (or, if applicable, the Reg AB Approved Entity) shall indemnify
and hold harmless the RFC, RAMP, their respective directors or officers and any
person controlling the RFC or RAMP, from and against any and all losses, claims,
damages and liabilities caused by (i) any untrue statement or alleged untrue
statement of a material fact contained in any information that Party A or such
Reg AB Approved Entity, as applicable, provides to RFC or RAMP pursuant to this
Section 18 (the "Party A Information") or caused by any omission or alleged
omission to state in the Party A Information a material fact required to be
stated therein or necessary to make the statements therein, in light of the
circumstances under which they were made, not misleading; or (ii) any failure by
Party A to deliver any information or other material when and as required under
this Section 18. RFC and RAMP shall be third party beneficiaries of Section 18.
RFC and RAMP shall be entitled to the rights and benefits of Section 18 and may
enforce the provisions of Section 18 as if they were a party hereto.

THAT IT WILL NOT SELL, TRANSFER OR ASSIGN THIS PURCHASE OPTION EXCEPT AS HEREIN
PROVIDED AND THE REGISTERED HOLDER OF THIS PURCHASE OPTION AGREES THAT IT WILL

                               FOR THE PURCHASE OF

                                 _________ UNITS

                                       OF

                      INTERAMERICAN ACQUISITION GROUP INC.

warrants included in the Units being registered for sale to the public by way of
the Registration Statement ("Public Warrants") except that the Warrants have an
exercise price of $6.65 per share ("Warrant Exercise Price"). If the Expiration
Date is a day on which banking institutions are authorized by law to

close, then this Purchase Option may be exercised on the next succeeding day
which is not such a day in accordance with the terms herein. During the period
ending on the Expiration Date, the Company agrees not to take any action that
would terminate the Purchase Option. This Purchase Option is initially
exercisable at $____ per Unit so purchased; provided, however, that upon the
occurrence of any of the events specified in Section 6 hereof, the rights
granted by this Purchase Option, including the exercise price per Unit and the
number of Units (and shares of Common Stock and Warrants) to be received upon
such exercise, shall be adjusted as therein specified. The term "Exercise Price"
shall mean the initial exercise price or the adjusted exercise price, depending
on the context.

2. Exercise.

         2.1 Exercise Form. In order to exercise this Purchase Option, the
exercise form attached hereto must be duly executed and completed and delivered
to the Company, together with this Purchase Option and payment of the Exercise
Price for the Units being purchased payable in cash or by certified check or
official bank check. If the subscription rights represented hereby shall not be
exercised at or before 5:00 p.m., Eastern time, on the Expiration Date this
Purchase Option shall become and be void without further force or effect, and
all rights represented hereby shall cease and expire.

         2.2 Legend. Each certificate for the securities purchased under this
Purchase Option shall bear a legend as follows unless such securities have been
registered under the Securities Act of 1933, as amended ("Act"):

                  "The securities represented by this certificate have not been
                  registered under the Securities Act of 1933, as amended
                  ("Act") or applicable state law. The securities may not be
                  offered for sale, sold or otherwise transferred except
                  pursuant to an effective registration statement under the Act,
                  or pursuant to an exemption from registration under the Act
                  and applicable state law."

         2.3      Cashless Exercise.

                  2.3.1 Determination of Amount. In lieu of the payment of the
Exercise Price multiplied by the number of Units for which this Purchase Option
is exercisable (and in lieu of being entitled to receive Common Stock and
Warrants) in the manner required by Section 2.1, the Holder shall have the right
(but not the obligation) to convert any exercisable but unexercised portion of
this Purchase Option into Units ("Conversion Right") as follows: upon exercise
of the Conversion Right, the Company shall deliver to the Holder (without
payment by the Holder of any of the Exercise Price in cash) that number of Units
(or that number of shares of Common Stock and Warrants (or that number of shares
of comprising that number of Units) equal to the quotient obtained by dividing
(x) the "Value" (as defined below) of the portion of the Purchase Option being
converted by (y) the Current Market Value (as defined below). The "Value" of the
portion of the Purchase Option being converted shall equal the remainder derived
from subtracting (a) (i) the Exercise Price multiplied by (ii) the number of
Units underlying the portion of this Purchase Option being converted from (b)
the Current Market Value of a Unit multiplied by the number of Units underlying
the portion of the Purchase Option being converted. As used herein, the term
"Current Market Value" per Unit at any date means: (A) in the event that neither
the Units nor Public Warrants are still trading, the remainder derived from
subtracting (x) the exercise price of the Warrants multiplied by the number of
shares of Common Stock issuable upon exercise of the Warrants underlying one
Unit from (y) (i) the Current Market Price of the Common Stock multiplied by
(ii) the number of shares of Common Stock underlying one Unit, which shall
include the shares of Common Stock underlying the Warrants included in such
Unit; (B) in the event that the Units, Common Stock and Public Warrants are
still trading, (i) if the Units are listed on a national securities exchange or
quoted on the Nasdaq National Market, Nasdaq SmallCap Market or NASD OTC
Bulletin Board (or successor exchange), the last sale price of the Units in the
principal trading market for the Units as reported by the exchange, Nasdaq or
the NASD, as the case may be, on the last trading day preceding the date in
question; or (ii) if the Units are not listed on a national securities exchange
or quoted on the Nasdaq National Market, Nasdaq SmallCap Market or the NASD OTC
Bulletin Board (or successor exchange), but is traded in the residual
over-the-counter market, the closing bid price for Units on the last trading day
preceding the date in question for which such quotations are reported by the
Pink Sheets, LLC or similar publisher of such quotations; and (C) in the event
that the Units are not still trading but the Common

                                       2

Stock and Public Warrants underlying the Units are still trading, the Current
Market Price of the Common Stock plus the product of (x) the Current Market
Price of the Public Warrants and (y) the number of shares of Common Stock
underlying the Warrants included in one Unit. The "Current Market Price" shall
mean (i) if the Common Stock (or Public Warrants, as the case may be) is listed
on a national securities exchange or quoted on the Nasdaq National Market,
Nasdaq SmallCap Market or NASD OTC Bulletin Board (or successor exchange), the
last sale price of the Common Stock (or Public Warrants) in the principal
trading market for the Common Stock as reported by the exchange, Nasdaq or the
NASD, as the case may be, on the last trading day preceding the date in
question; (ii) if the Common Stock (or Public Warrants, as the case may be) is
not listed on a national securities exchange or quoted on the Nasdaq National
Market, Nasdaq SmallCap Market or the NASD OTC Bulletin Board (or successor
exchange), but is traded in the residual over-the-counter market, the closing
bid price for the Common Stock (or Public Warrants) on the last trading day
preceding the date in question for which such quotations are reported by the
Pink Sheets, LLC or similar publisher of such quotations; and (iii) if the fair
market value of the Common Stock cannot be determined pursuant to clause (i) or
(ii) above, such price as the Board of Directors of the Company shall determine,
in good faith. In the event the Public Warrants have expired and are no longer
exercisable, no "Value" shall be attributed to the Warrants underlying this
Purchase Option. Additionally, in the event this Purchase Option is exercised
pursuant to this Section 2.3 and the Public Warrants are still trading, the
"Value" shall be reduced by the difference between the Warrant Exercise Price
and the exercise price of the Public Warrants.

                  2.3.2 Mechanics of Cashless Exercise. The Cashless Exercise
Right may be exercised by the Holder on any business day on or after the
Commencement Date and not later than the Expiration Date by delivering the
Purchase Option with the duly executed exercise form attached hereto with the
cashless exercise section completed to the Company, exercising the Cashless
Exercise Right and specifying the total number of Units the Holder will purchase
pursuant to such Cashless Exercise Right.

                  2.4 Physical Settlement Only. This Purchase Option may not be
exercised by, or securities issued to, any registered holder in any state in
which such exercise or issuance would be unlawful. In no event will the
registered holder of this Purchase Option be entitled to receive a net-cash
settlement in lieu of physical settlement in Units, Common Stock or Warrants,
regardless of whether the Units, Common Stock or Warrants underlying the
Purchase Option are registered pursuant to an effective registration statement.

3. Transfer.

         3.1 General Restrictions. The registered Holder of this Purchase
Option, by its acceptance hereof, agrees that it will not sell, transfer,
assign, pledge or hypothecate this Purchase Option for a period of one year
following the Effective Date to anyone other than (i) Rodman or an underwriter
or a selected dealer in connection with the Offering, or (ii) a bona fide
officer or partner of Rodman or of any such underwriter or selected dealer. On
and after the first anniversary of the Effective Date, transfers to others may
be made subject to compliance with or exemptions from applicable securities
laws. In order to make any permitted assignment, the Holder must deliver to the
Company the assignment form attached hereto duly executed and completed,
together with the Purchase Option and payment of all transfer taxes, if any,
payable in connection therewith. The Company shall within five business days
transfer this Purchase Option on the books of the Company and shall execute and
deliver a new Purchase Option or Purchase Options of like tenor to the
appropriate assignee(s) expressly evidencing the right to purchase the aggregate
number of Units purchasable hereunder or such portion of such number as shall be

                                       3

contemplated by any such assignment.

         3.2 Restrictions Imposed by the Act. The securities evidenced by this
Purchase Option shall not be transferred unless and until (i) the Company has
received the opinion of counsel for the Holder that the securities may be
transferred pursuant to an exemption from registration under the Act and
applicable state securities laws, the availability of which is established to
the reasonable satisfaction of the Company, or (ii) a registration statement or
a post-effective amendment to the Registration Statement relating to such
securities has been filed by the Company and declared effective by the
Securities and Exchange Commission (the "Commission") and compliance with
applicable state securities law has been established.

4. New Purchase Options to be Issued.

         4.1 Partial Exercise or Transfer. Subject to the restrictions in
Section 3 hereof, this Purchase Option may be exercised or assigned in whole or
in part. In the event of the exercise or assignment hereof in part only, upon
surrender of this Purchase Option for cancellation, together with the duly
executed exercise or assignment form and funds sufficient to pay any Exercise
Price and/or transfer tax, the Company shall cause to be delivered to the Holder
without charge a new Purchase Option of like tenor to this Purchase Option in
the name of the Holder evidencing the right of the Holder to purchase the number
of Units purchasable hereunder as to which this Purchase Option has not been
exercised or assigned.

         4.2 Lost Certificate. Upon receipt by the Company of evidence
satisfactory to it of the loss, theft, destruction or mutilation of this
Purchase Option and of reasonably satisfactory indemnification or the posting of
a bond, the Company shall execute and deliver a new Purchase Option of like
tenor and date. Any such new Purchase Option executed and delivered as a result
of such loss, theft, mutilation or destruction shall constitute a substitute
contractual obligation on the part of the Company.

5.       Registration Rights.

         5.1      Demand Registration.

                  5.1.1 Grant of Right. The Company, upon written demand
("Initial Demand Notice") of the Holder(s) of at least 51% of the Purchase
Options and/or the underlying Units and/or the underlying securities ("Majority
Holders"), agrees to register (the "Demand Registration") on one occasion, all
or any portion of the Purchase Options requested by the Majority Holders in the
Initial Demand Notice and all of the securities underlying such Purchase
Options, including the Units, Common Stock, the Warrants and the Common Stock
underlying the Warrants (collectively, the "Registrable Securities"). On such
occasion, the Company will file a registration statement or a post-effective
amendment to the Registration Statement covering the Registrable Securities
within sixty days after receipt of the Initial Demand Notice and use its best
efforts to have such registration statement or post-effective amendment declared
effective as soon as possible thereafter. The demand for registration may be
made at any time during a period of five years beginning on the Effective Date.
The Initial Demand Notice shall specify the number of shares of Registrable
Securities proposed to be sold and the intended method(s) of distribution
thereof. The Company covenants and agrees to give written notice of its receipt
of any Initial Demand Notice by any Holder(s) to all other registered Holders of
the Purchase Options and/or the Registrable Securities within ten days from the
date of the receipt of any such Initial Demand Notice. Each holder of
Registrable Securities who wishes to include all or a portion of such holder's
Registrable Securities in the Demand Registration (each such holder including
shares of Registrable

                                       4

Securities in such registration , a "Demanding Holder") shall so notify the
Company within fifteen (15) days after the receipt by the holder of the notice
from the Company. Upon any such request, the Demanding Holders shall be entitled
to have their Registrable Securities included in the Demand Registration.

                  5.1.2 Effective Registration. A registration will not count as
a Demand Registration until the registration statement filed with the Commission
with respect to such Demand Registration has been declared effective and the
Company has complied with all of its obligations under this Purchase Option with
respect thereto; provided, however, that if, after such registration statement
has been declared effective, the offering of Registrable Securities pursuant to
a Demand Registration is interfered with by any stop order or injunction of the
Commission or any other governmental agency or court, the registration statement
with respect to such Demand Registration will be deemed not to have been
declared effective, unless and until, (i) such stop order or injunction is
removed, rescinded or otherwise terminated, and (ii) a majority-in-interest of
the Demanding Holders thereafter elect to continue the offering.

                  5.1.3. Underwritten Offering. If the Majority Holders so elect
and such holders so advise the Company as part of the Initial Demand Notice, the
offering of such Registrable Securities pursuant to such Demand Registration
shall be in the form of an underwritten offering. In such event, the right of
any holder to include its 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 to the
extent provided herein. All Demanding Holders proposing to distribute their
securities through such underwriting shall enter into an underwriting agreement
in customary form with the underwriter or underwriters selected for such
underwriting by the Majority Holders.

                  5.1.4 Reduction of Offering. If the managing underwriter or
underwriters for a Demand Registration that is to be an underwritten offering
advises the Company and the Demanding Holders in writing that the dollar amount
or number of shares of Registrable Securities which the Demanding Holders desire
to sell, taken together with all other shares of Common Stock or other
securities which the Company desires to sell and the shares of Common Stock, if
any, as to which registration has been requested pursuant to written contractual
piggy-back registration rights held by other stockholders of the Company who
desire to sell, exceeds the maximum dollar amount or maximum number of shares
that can be sold in such offering without adversely affecting the proposed
offering price, the timing, the distribution method, or the probability of
success of such offering (such maximum dollar amount or maximum number of
shares, as applicable, the "Maximum Number of Shares"), then the Company shall
include in such registration: (i) first, the Registrable Securities as to which
Demand Registration has been requested by the Demanding Holders (pro rata in
accordance with the number of shares that each such person has requested be
included in such registration, regardless of the number of shares held by each
such person (such proportion is referred to herein as "Pro Rata")) that can be
sold without exceeding the Maximum Number of Shares; (ii) second, to the extent
that the Maximum Number of Shares has not been reached under the foregoing
clause (i), the shares of Common Stock or other securities that the Company
desires to sell that can be sold without exceeding the Maximum Number of Shares;
(iii) third, to the extent that the Maximum Number of Shares has not been
reached under the foregoing clauses (i) and (ii), the shares of Common Stock or
other securities registrable pursuant to the terms of the Registration Rights
Agreement between the Company and the initial investors in the Company, dated as
of ________, 2006 (the "Registration Rights Agreement" and such registrable
securities, the "Investor Securities") as to which "piggy-back" registration has
been requested by the holders thereof, Pro Rata, that can be sold without
exceeding the Maximum Number of Shares; and (iv) fourth, to the extent that the
Maximum Number of Shares have not been reached under the foregoing

                                       5

clauses (i), (ii), and (iii), the shares of Common Stock or other securities for
the account of other persons that the Company is obligated to register pursuant
to written contractual arrangements with such persons and that can be sold
without exceeding the Maximum Number of Shares.

                  5.1.5 Withdrawal. If a majority-in-interest of the Demanding
Holders disapprove of the terms of any underwriting or are not entitled to
include all of their Registrable Securities in any offering, such
majority-in-interest of the Demanding Holders may elect to withdraw from such
offering by giving written notice to the Company and the underwriter or
underwriters of their request to withdraw prior to the effectiveness of the
registration statement filed with the Commission with respect to such Demand
Registration. If the majority-in-interest of the Demanding Holders withdraws
from a proposed offering relating to a Demand Registration, then such
registration shall not count as a Demand Registration provided for in Section
5.1.

                  5.1.6 Terms. The Company shall bear all fees and expenses
attendant to registering the Registrable Securities, including the expenses of
any legal counsel selected by the Holders to represent them in connection with
the sale of the Registrable Securities, but the Holders shall pay any and all
underwriting commissions. The Company agrees to use its reasonable best efforts
to qualify or register the Registrable Securities in such States as are
reasonably requested by the Majority Holder(s); provided, however, that in no
event shall the Company be required to register the Registrable Securities in a
State in which such registration would cause (i) the Company to be obligated to
qualify to do business in such State, or would subject the Company to taxation
as a foreign corporation doing business in such jurisdiction or (ii) the
principal stockholders of the Company to be obligated to escrow their shares of
capital stock of the Company. The Company shall cause any registration statement
or post-effective amendment filed pursuant to the demand rights granted under
Section 5.1.1 to remain effective for a period of nine consecutive months from
the effective date of such registration statement or post-effective amendment.

         5.2      "Piggy-Back" Registration.

                  5.2.1 Grant of Right. In addition to the demand right of
registration, the Holders of the Purchase Options shall have the right for a
period of seven years commencing on the Effective Date, to include the
Registrable Securities as part of any other registration of securities filed by
the Company (other than in connection with a transaction contemplated by Rule
145(a) promulgated under the Act or pursuant to Form S-8); provided, however,
that if, in the written opinion of the Company's managing underwriter or
underwriters, if any, for such offering, the inclusion of the Registrable
Securities, when added to the securities being registered by the Company or the
selling stockholder(s), will exceed the maximum amount of the Company's
securities which can be marketed (i) at a price reasonably related to their then
current market value, and (ii) without materially and adversely affecting the
entire offering, then the Company will still be required to include the
Registrable Securities, but may require the Holders to agree, in writing, to
delay the sale of all or any portion of the Registrable Securities for a period
of 90 days from the effective date of the offering, provided, further, that if
the sale of any Registrable Securities is so delayed, then the number of
securities to be sold by all stockholders in such public offering during such 90
day period shall be apportioned pro rata among all such selling stockholders,
including all holders of the Registrable Securities, according to the total
amount of securities of the Company owned by said selling stockholders,
including all holders of the Registrable Securities. The Company shall give
written notice of such proposed filing to the Holders of the Purchase Options as
soon as practicable, but in no event less than ten (10) days before the
anticipated filing date, which notice shall describe the amount and type of
securities to be included in such offering, the intended method(s) of
distribution, and the name of the proposed managing underwriter or underwriters,
if any, of the offering,

                                       6

and offer the Holders in such notice the opportunity to register the sale of
such number of shares of Registrable Securities as such holders may request in
writing within five (5) days following receipt of such notice (a "Piggy-Back
Registration"). All Holders proposing to distribute their Registrable Securities
through a Piggy-Back Registration that involves an underwriter or underwriters
shall enter into an underwriting agreement in customary form with the
underwriter or underwriters selected for such Piggy-Back Registration.

                  5.2.2 Withdrawal. Any Holder of Registrable Securities may
elect to withdraw such Holder's request for inclusion of Registrable Securities
in any Piggy-Back Registration by giving written notice to the Company of such
request to withdraw prior to the effectiveness of the registration statement.
The Company (whether on its own determination or as the result of a withdrawal
by persons making a demand pursuant to written contractual obligations) may
withdraw a registration statement at any time prior to the effectiveness of the
registration statement. Notwithstanding any such withdrawal, the Company shall
pay all expenses incurred by the holders of Registrable Securities in connection
with such Piggy-Back Registration as provided in Section 5.2.3.

                  5.2.3 Terms. The Company shall bear all fees and expenses
attendant to registering the Registrable Securities, including the expenses of
any legal counsel selected by the Holders to represent them in connection with
the sale of the Registrable Securities but the Holders shall pay any and all
underwriting commissions related to the Registrable Securities. In the event of
such a proposed registration, the Company shall furnish the then Holders of
outstanding Registrable Securities with not less than fifteen days written
notice prior to the proposed date of filing of such registration statement. Such
notice to the Holders shall continue to be given for each applicable
registration statement filed (during the period in which the Purchase Option is
exercisable) by the Company until such time as all of the Registrable Securities
have been registered and sold. The holders of the Registrable Securities shall
exercise the "piggy-back" rights provided for herein by giving written notice,
within ten days of the receipt of the Company's notice of its intention to file
a registration statement. The Company shall cause any registration statement
filed pursuant to the above "piggyback" rights to remain effective for at least
nine months from the date that the Holders of the Registrable Securities are
first given the opportunity to sell all of such securities.

         5.3 Damages. Should the registration or the effectiveness thereof
required by Sections 5.1 and 5.2 hereof be delayed by the Company or the Company
otherwise fails to comply with such provisions, the Company shall, in addition
to any other equitable or other relief available to the Holder(s), be liable for
any and all incidental, special and consequential damages sustained by the
Holder(s), including, but not limited to, the loss of any profits that might
have been received by the holder upon the sale of shares of Common Stock or
Warrants (and shares of Common Stock underlying the Warrants) underlying this
Purchase Option.

         5.4      General Terms.
                  -------------

                  5.4.1 Indemnification. The Company shall indemnify the
Holder(s) of the Registrable Securities to be sold pursuant to any registration
statement hereunder and each person, if any, who controls such Holders within
the meaning of Section 15 of the Act or Section 20(a) of the Securities Exchange
Act of 1934, as amended ("Exchange Act"), against all loss, claim, damage,
expense or liability (including all reasonable attorneys' fees and other
expenses reasonably incurred in investigating, preparing or defending against
litigation, commenced or threatened, or any claim whatsoever whether arising out
of any action between the underwriter and the Company or between the underwriter
and any third party or otherwise) to which any of them may become subject under
the Act, the Exchange Act or

                                       7

otherwise, arising from such registration statement but only to the same extent
and with the same effect as the provisions pursuant to which the Company has
agreed to indemnify the underwriters contained in Section 5 of the Underwriting
Agreement between the Company, Rodman and the other underwriters named therein
dated the Effective Date. The Holder(s) of the Registrable Securities to be sold
pursuant to such registration statement, and their successors and assigns, shall
severally, and not jointly, indemnify the Company, its officers and directors
and each person, if any, who controls the Company within the meaning of Section
15 of the Act or Section 20(a) of the Exchange Act, against all loss, claim,
damage, expense or liability (including all reasonable attorneys' fees and other
expenses reasonably incurred in investigating, preparing or defending against
any claim whatsoever) to which they may become subject under the Act, the
Exchange Act or otherwise, arising from information furnished by or on behalf of
such Holders, or their successors or assigns, in writing, for specific inclusion
in such registration statement to the same extent and with the same effect as
the provisions contained in Section 5 of the Underwriting Agreement pursuant to
which the underwriters have agreed to indemnify the Company.

                  5.4.2 Exercise of Purchase Options. Nothing contained in this
Purchase Option shall be construed as requiring the Holder(s) to exercise their
Purchase Options or Warrants underlying such Purchase Options prior to or after
the initial filing of any registration statement or the effectiveness thereof.

                  5.4.3 Documents Delivered to Holders. The Company shall
furnish Rodman, as representative of the Holders participating in any of the
foregoing offerings, a signed counterpart, addressed to the participating
Holders, of (i) an opinion of counsel to the Company, dated the effective date
of such registration statement (and, if such registration includes an
underwritten public offering, an opinion dated the date of the closing under any
underwriting agreement related thereto), and (ii) a "cold comfort" letter dated
the effective date of such registration statement (and, if such registration
includes an underwritten public offering, a letter dated the date of the closing
under the underwriting agreement) signed by the independent public accountants
who have issued a report on the Company's financial statements included in such
registration statement, in each case covering substantially the same matters
with respect to such registration statement (and the prospectus included
therein) and, in the case of such accountants' letter, with respect to events
subsequent to the date of such financial statements, as are customarily covered
in opinions of issuer's counsel and in accountants' letters delivered to
underwriters in underwritten public offerings of securities. The Company shall
also deliver promptly to Rodman, as representative of the Holders participating
in the offering, the correspondence and memoranda described below and copies of
all correspondence between the Commission and the Company, its counsel or
auditors and all memoranda relating to discussions with the Commission or its
staff with respect to the registration statement and permit Rodman, as
representative of the Holders, to do such investigation, upon reasonable advance
notice, with respect to information contained in or omitted from the
registration statement as it deems reasonably necessary to comply with
applicable securities laws or rules of the National Association of Securities
Dealers, Inc. ("NASD"). Such investigation shall include access to books,
records and properties and opportunities to discuss the business of the Company
with its officers and independent auditors, all to such reasonable extent and at
such reasonable times and as often as Rodman, as representative of the Holders,
shall reasonably request. The Company shall not be required to disclose any
confidential information or other records to Rodman, as representative of the
Holders, or to any other person, until and unless such persons shall have
entered into reasonable confidentiality agreements (in form and substance
reasonably satisfactory to the Company), with the Company with respect thereto.

                  5.4.4 Underwriting Agreement. The Company shall enter into an
underwriting agreement with the managing underwriter(s), if any, selected by any
Holders whose Registrable Securities are being registered pursuant to this
Section 5, which managing underwriter shall be

                                       8

reasonably acceptable to the Company. Such agreement shall be reasonably
satisfactory in form and substance to the Company, each Holder and such managing
underwriters, and shall contain such representations, warranties and covenants
by the Company and such other terms as are customarily contained in agreements
of that type used by the managing underwriter. The Holders shall be parties to
any underwriting agreement relating to an underwritten sale of their Registrable
Securities and may, at their option, require that any or all the
representations, warranties and covenants of the Company to or for the benefit
of such underwriters shall also be made to and for the benefit of such Holders.
Such Holders shall not be required to make any representations or warranties to
or agreements with the Company or the underwriters except as they may relate to
such Holders and their intended methods of distribution. Such Holders, however,
shall agree to such covenants and indemnification and contribution obligations
for selling stockholders as are customarily contained in agreements of that type
used by the managing underwriter. Further, such Holders shall execute
appropriate custody agreements and otherwise cooperate fully in the preparation
of the registration statement and other documents relating to any offering in
which they include securities pursuant to this Section 5. Each Holder shall also
furnish to the Company such information regarding itself, the Registrable
Securities held by it, and the intended method of disposition of such securities
as shall be reasonably required to effect the registration of the Registrable
Securities.

                  5.4.5 Rule 144 Sale. Notwithstanding anything contained in
this Section 5 to the contrary, the Company shall have no obligation pursuant to
Sections 5.1 or 5.2 for the registration of Registrable Securities held by any
Holder (i) where such Holder would then be entitled to sell under Rule 144
within any three-month period (or such other period prescribed under Rule 144 as
may be provided by amendment thereof) all of the Registrable Securities then
held by such Holder, and (ii) where the number of Registrable Securities held by
such Holder is within the volume limitations under paragraph (e) of Rule 144
(calculated as if such Holder were an affiliate within the meaning of Rule 144).

                  5.4.6 Supplemental Prospectus. Each Holder agrees, that upon
receipt of any notice from the Company of the happening of any event as a result
of which the prospectus included in the 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 light of the circumstances then existing, such Holder
will immediately discontinue disposition of Registrable Securities pursuant to
the Registration Statement covering such Registrable Securities until such
Holder's receipt of the copies of a supplemental or amended prospectus, and, if
so desired by the Company, such Holder shall deliver to the Company (at the
expense of the Company) or destroy (and deliver to the Company a certificate of
such destruction) all copies, other than permanent file copies then in such
Holder's possession, of the prospectus covering such Registrable Securities
current at the time of receipt of such notice.

6.       Adjustments.

         6.1 Adjustments to Exercise Price and Number of Securities. The
Exercise Price and the number of Units underlying the Purchase Option shall be
subject to adjustment from time to time as hereinafter set forth:

                  6.1.1 Stock Dividends - Split-Ups. If after the date hereof,
and subject to the provisions of Section 6.4 below, the number of outstanding
shares of Common Stock is increased by a stock dividend payable in shares of
Common Stock or by a split-up of shares of Common Stock or other similar event,
then, on the effective date thereof, the number of shares of Common Stock
underlying each

                                       9

of the Units purchasable hereunder shall be increased in proportion to such
increase in outstanding shares. In such case, the number of shares of Common
Stock, and the exercise price applicable thereto, underlying the Warrants
underlying each of the Units purchasable hereunder shall be adjusted in
accordance with the terms of the Warrants. For example, if the Company declares
a two-for-one stock dividend and at the time of such dividend this Purchase
Option is for the purchase of one Unit at $6.60 per whole Unit (each Warrant
underlying the Units is exercisable for $5.00 per share), upon effectiveness of
the dividend, this Purchase Option will be adjusted to allow for the purchase of
one Unit at $6.60 per Unit, each Unit entitling the holder to receive two shares
of Common Stock and four Warrants (each Warrant exercisable for $2.50 per
share).

                  6.1.2 Aggregation of Shares. If after the date hereof, and
subject to the provisions of Section 6.4, the number of outstanding shares of
Common Stock is decreased by a consolidation, combination or reclassification of
shares of Common Stock or other similar event, then, on the effective date
thereof, the number of shares of Common Stock underlying each of the Units
purchasable hereunder shall be decreased in proportion to such decrease in
outstanding shares. In such case, the number of shares of Common Stock, and the
exercise price applicable thereto, underlying the Warrants underlying each of
the Units purchasable hereunder shall be adjusted in accordance with the terms
of the Warrants.

                  6.1.3 Replacement of Securities upon Reorganization, etc. In
case of any reclassification or reorganization of the outstanding shares of
Common Stock other than a change covered by Section 6.1.1 or 6.1.2 hereof or
that solely affects the par value of such shares of Common Stock, or in the case
of any merger or consolidation of the Company with or into another corporation
(other than a consolidation or merger in which the Company is the continuing
corporation and that does not result in any reclassification or reorganization
of the outstanding shares of Common Stock), or in the case of any sale or
conveyance to another corporation or entity of the property of the Company as an
entirety or substantially as an entirety in connection with which the Company is
dissolved, the Holder of this Purchase Option shall have the right thereafter
(until the expiration of the right of exercise of this Purchase Option) to
receive upon the exercise hereof, for the same aggregate Exercise Price payable
hereunder immediately prior to such event, the kind and amount of shares of
stock or other securities or property (including cash) receivable upon such
reclassification, reorganization, merger or consolidation, or upon a dissolution
following any such sale or transfer, by a Holder of the number of shares of
Common Stock of the Company obtainable upon exercise of this Purchase Option and
the underlying Warrants immediately prior to such event; and if any
reclassification also results in a change in shares of Common Stock covered by
Section 6.1.1 or 6.1.2, then such adjustment shall be made pursuant to Sections
6.1.1, 6.1.2 and this Section 6.1.3. The provisions of this Section 6.1.3 shall
similarly apply to successive reclassifications, reorganizations, mergers or
consolidations, sales or other transfers.

                  6.1.4 Changes in Form of Purchase Option. This form of
Purchase Option need not be changed because of any change pursuant to this
Section, and Purchase Options issued after such change may state the same
Exercise Price and the same number of Units as are stated in the Purchase
Options initially issued pursuant to this Agreement. The acceptance by any
Holder of the issuance of new Purchase Options reflecting a required or
permissive change shall not be deemed to waive any rights to an adjustment
occurring after the Commencement Date or the computation thereof.

         6.2      [Intentionally Omitted]

         6.3 Substitute Purchase Option. In case of any consolidation of the
Company with, or merger of the Company with, or merger of the Company into,
another corporation (other than a consolidation or merger which does not result
in any reclassification or change of the outstanding

                                       10

Common Stock), the corporation formed by such consolidation or merger shall
execute and deliver to the Holder a supplemental Purchase Option providing that
the holder of each Purchase Option then outstanding or to be outstanding shall
have the right thereafter (until the stated expiration of such Purchase Option)
to receive, upon exercise of such Purchase Option, the kind and amount of shares
of stock and other securities and property receivable upon such consolidation or
merger, by a holder of the number of shares of Common Stock of the Company for
which such Purchase Option might have been exercised immediately prior to such
consolidation, merger, sale or transfer. Such supplemental Purchase Option shall
provide for adjustments which shall be identical to the adjustments provided in
Section 6. The above provision of this Section shall similarly apply to
successive consolidations or mergers.

         6.4 Elimination of Fractional Interests. The Company shall not be
required to issue certificates representing fractions of shares of Common Stock
or Warrants upon the exercise of the Purchase Option, nor shall it be required
to issue scrip or pay cash in lieu of any fractional interests, it being the
intent of the parties that all fractional interests shall be eliminated by
rounding any fraction up to the nearest whole number of Warrants, shares of
Common Stock or other securities, properties or rights.

7. Reservation and Listing. The Company shall at all times reserve and keep
available out of its authorized shares of Common Stock, solely for the purpose
of issuance upon exercise of the Purchase Options or the Warrants underlying the
Purchase Option, such number of shares of Common Stock or other securities,
properties or rights as shall be issuable upon the exercise thereof. The Company
covenants and agrees that, upon exercise of the Purchase Options and payment of
the Exercise Price therefor, all shares of Common Stock and other securities
issuable upon such exercise shall be duly and validly issued, fully paid and
non-assessable and not subject to preemptive rights of any stockholder. The
Company further covenants and agrees that upon exercise of the Warrants
underlying the Purchase Options and payment of the respective Warrant exercise
price therefor, all shares of Common Stock and other securities issuable upon
such exercise shall be duly and validly issued, fully paid and non-assessable
and not subject to preemptive rights of any stockholder. As long as the Purchase
Options shall be outstanding, the Company shall use its best efforts to cause
all (i) Units and shares of Common Stock issuable upon exercise of the Purchase
Options, (ii) Warrants issuable upon exercise of the Purchase Options and (iii)
shares of Common Stock issuable upon exercise of the Warrants included in the
Units issuable upon exercise of the Purchase Option to be listed (subject to
official notice of issuance) on all securities exchanges (or, if applicable on
the Nasdaq National Market, SmallCap Market, OTC Bulletin Board or any successor
trading market) on which the Units, the Common Stock or the Public Warrants
issued to the public in connection herewith may then be listed and/or quoted.

                                       11

8. Certain Notice Requirements.

         8.1 Holder's Right to Receive Notice. Nothing herein shall be construed
as conferring upon the Holders the right to vote or consent as a stockholder for
the election of directors or any other matter, or as having any rights
whatsoever as a stockholder of the Company. If, however, at any time prior to
the expiration of the Purchase Options and their exercise, any of the events
described in Section 8.2 shall occur, then, in one or more of said events, the
Company shall give written notice of such event at least fifteen days prior to
the date fixed as a record date or the date of closing the transfer books for
the determination of the stockholders entitled to such dividend, distribution,
conversion or exchange of securities or subscription rights, or entitled to vote
on such proposed dissolution, liquidation, winding up or sale. Such notice shall
specify such record date or the date of the closing of the transfer books, as
the case may be. Notwithstanding the foregoing, the Company shall deliver to
each Holder a copy of each notice given to the other stockholders of the Company
at the same time and in the same manner that such notice is given to the
stockholders.

         8.2 Events Requiring Notice. The Company shall be required to give the
notice described in this Section 8 upon one or more of the following events: (i)
if the Company shall take a record of the holders of its shares of Common Stock
for the purpose of entitling them to receive a dividend or distribution payable
otherwise than in cash, or a cash dividend or distribution payable otherwise
than out of retained earnings, as indicated by the accounting treatment of such
dividend or distribution on the books of the Company, or (ii) the Company shall
offer to all the holders of its Common Stock any additional shares of capital
stock of the Company or securities convertible into or exchangeable for shares
of capital stock of the Company, or any option, right or warrant to subscribe
therefor, or (iii) a dissolution, liquidation or winding up of the Company
(other than in connection with a consolidation or merger) or a sale of all or
substantially all of its property, assets and business shall be proposed.

         8.3 Notice of Change in Exercise Price. The Company shall, promptly
after an event requiring a change in the Exercise Price pursuant to Section 6
hereof, send notice to the Holders of such event and change ("Price Notice").
The Price Notice shall describe the event causing the change and the method of
calculating same and shall be certified as being true and accurate by the
Company's President and Chief Financial Officer.

         8.4 Transmittal of Notices. All notices, requests, consents and other
communications under this Purchase Option shall be in writing and shall be
deemed to have been duly made when hand delivered, or mailed by express mail or
private courier service: (i) If to the registered Holder of the Purchase Option,
to the address of such Holder as shown on the books of the Company, or (ii) if
to the Company, to the following address or to such other address as the Company
may designate by notice to the Holders:

                        InterAmerican Acquisition Group Inc.
                        2918 Fifth Avenue South, Suite 209
                        San Diego, California 92103
                        Attn:   William C. Morro, Chief Executive Officer

                                       12

9. Miscellaneous.

         9.1 Amendments. The Company and Rodman may from time to time
supplement or amend this Purchase Option without the approval of any of the
Holders in order to cure any ambiguity, to correct or supplement any provision
contained herein that may be defective or inconsistent with any other provisions
herein, or to make any other provisions in regard to matters or questions
arising hereunder that the Company and Granite may deem necessary or desirable
and that the Company and Granite deem shall not adversely affect the interest of
the Holders. All other modifications or amendments shall require the written
consent of and be signed by the party against whom enforcement of the
modification or amendment is sought.

         9.2 Headings. The headings contained herein are for the sole purpose of
convenience of reference, and shall not in any way limit or affect the meaning
or interpretation of any of the terms or provisions of this Purchase Option.

10. Entire Agreement. This Purchase Option (together with the other agreements
and documents being delivered pursuant to or in connection with this Purchase
Option) constitutes the entire agreement of the parties hereto with respect to
the subject matter hereof, and supersedes all prior agreements and
understandings of the parties, oral and written, with respect to the subject
matter hereof.

         10.1 Binding Effect. This Purchase Option shall inure solely to the
benefit of and shall be binding upon, the Holder and the Company and their
permitted assignees, respective successors, legal representatives and assigns,
and no other person shall have or be construed to have any legal or equitable
right, remedy or claim under or in respect of or by virtue of this Purchase
Option or any provisions herein contained.

         10.2 Governing Law; Submission to Jurisdiction. This Purchase Option
shall be governed by and construed and enforced in accordance with the laws of
the State of New York, without giving effect to conflicts of law principles that
would result in the application of the substantive laws of another jurisdiction.
The Company hereby agrees that any action, proceeding or claim against it
arising out of, or relating in any way to this Purchase Option shall be brought
and enforced in the courts of the State of New York or of the United States of
America for the Southern District of New York, and irrevocably submits to such
jurisdiction, which jurisdiction shall be exclusive. The Company hereby waives
any objection to such exclusive jurisdiction and that such courts represent an
inconvenient forum. Any process or summons to be served upon the Company may be
served by transmitting a copy thereof by registered or certified mail, return
receipt requested, postage prepaid, addressed to it at the address set forth in
Section 8 hereof. Such mailing shall be deemed personal service and shall be
legal and binding upon the Company in any action, proceeding or claim. The
Company and the Holder agree that the prevailing party(ies) in any such action
shall be entitled to recover from the other party(ies) all of its reasonable
attorneys' fees and expenses relating to such action or proceeding and/or
incurred in connection with the preparation therefor.

         10.3 Waiver, Etc. The failure of the Company or the Holder to at any
time enforce any of the provisions of this Purchase Option shall not be deemed
or construed to be a waiver of any such provision, nor to in any way affect the
validity of this Purchase Option or any provision hereof or the right of the
Company or any Holder to thereafter enforce each and every provision of this
Purchase Option. No waiver of any breach, non-compliance or non-fulfillment of
any of the provisions of this Purchase Option shall be effective unless set
forth in a written instrument executed by the party or parties against whom or
which enforcement of such waiver is sought; and no waiver of any such breach,
non-compliance or non-

                                       13

fulfillment shall be construed or deemed to be a waiver of
any other or subsequent breach, non-compliance or non-fulfillment.
