      This Escrow Agreement (herein so called), dated _______________, made by
and between Mewbourne Development Corporation, a Delaware Corporation ("MD"),
and Regions Bank - Tyler ("Escrow Agent");

      WHEREAS, MD will serve as the Managing Partner of Mewbourne Energy

prospects through drilling and producing oil and gas thereon (the "Programs");

      WHEREAS, the Form S-1 Registration Statement (the "Statement") dated
______________, relating to the interests to be sold provides that subscription
proceeds for such Interests ("Subscription Proceeds") from investors who are
initially approved by MD will be deposited in an escrow account with Escrow
Agent and may not be contributed to the capital of a Partnership unless at the
end of the subscription period the aggregate Subscription Proceeds of over
$5,000,000 have been received and accepted for a Partnership and certain other
conditions have been met;

      WHEREAS, the Statement relating to the Interests to be sold provides that
investors desiring to purchase Interests in a Partnership shall provide MD with
certain information concerning their suitability for investment in the
Partnership by completing the Subscription Agreement (the "Subscription
Agreement"); and

      WHEREAS, MD desires that Escrow Agent provide procedures for the deposit
and safekeeping of the Subscription Proceeds and delivery of the Subscription
Agreement to MD subject to the terms of this Escrow Agreement;

      NOW, THEREFORE, in consideration of the mutual promises herein set forth,
and for other good and valuable consideration, the receipt and sufficiency of
which are hereby acknowledged, the parties hereto covenant and agree as follows:

the terms of this Escrow

<PAGE>

Agreement. The Subscription Proceeds so deposited, together with any and all
interest earned thereon, are referred to as the "Escrow Funds".

      3. Duties of Escrow Agent. The Escrow Agent shall have the following
general duties: (a) to promptly deliver the Subscription Agreement to MD; (b) to
deposit and safely maintain the Escrow Funds in the Account, guarding at all
times against the commingling thereof with any funds of MD or its affiliates
during the term of this Escrow Agreement; (c) at the direction of MD, to invest
the Escrow Funds in investments that are permissible under rule 15c2-4
promulgated by the Securities and Exchange Commission under the Securities
Exchange Act of 1934, as amended, including, without limitation (if
permissible), time deposits, short-term bank certificates of deposit, short-term
governmental obligations and bank money market accounts to be held by Escrow
Agent; (d) to prepare and maintain true and complete records with respect to the
Escrow Funds, including the name of each subscriber and the portion of the
Escrow Funds from time to time attributable to him; and (e) to disburse the
Escrow Funds in accordance with the terms of this Escrow Agreement.

      4. Payment of Escrow Funds. The Escrow Funds, or portions thereof, shall
be paid out by Escrow Agent in accordance with written instructions from MD as
follows: (a) to each subscriber, if any, whose subscription has been rejected by
MD within five business days after the clearance of those Escrow Funds, that
portion of the Escrow Funds attributable to that subscriber as shown on Escrow
Agent's records, including any interest earned thereon; (b) to each subscriber,
if any, whose Subscription Proceeds have not been contributed to the Partnership
prior to the termination of the offering period for Interests in the
Partnership, and any subscriber who may be rejected as an Investor Partner
subsequent to the period described in Subsection (a) of this Section 4, that
portion of the Escrow Funds attributable to the rejected subscriber as shown on
Escrow Agent's records together with any interest attributable thereto (as
calculated by MD); (c) to each subscriber, if any, whose subscription has been
reduced, that portion of the Escrow Funds equal to the amount of such reduction
attributable thereto as shown on Escrow Agent's records; (d) to MD for
distribution to each subscriber within 60 days of closing of the Partnership,
that portion of accrued and unpaid interest on the Escrow Funds relating to such
Partnership, which Escrow Funds were deposited no fewer than five business days
prior to the termination of the offering of Interests in the Partnership,
attributable to that subscriber as shown on Escrow Agent's records; and (e) to
an account for the Partnership all remaining Escrow Funds attributable to the
Partnership. Notwithstanding the foregoing, no portion of the Escrow Funds may
be paid to the Partnership unless the Escrow Agent shall have in excess of
$5,000,000 in Escrow Funds with respect to the Partnership and MD informs the
Escrow Agent in writing that aggregate Subscription Proceeds for Interests in
the Partnership of $5,000,000 or more have been received and cleared from
subscribers that MD initially approves as suitable to be Investor Partners (as
such term is defined in the Statement) in that Partnership. Notwithstanding the
provisions of this Section 4, or any other provision of this Escrow Agreement,
after the Escrow Agent shall have in excess of $5,000,000 in Escrow Funds with
respect to that Partnership and MD informs the Escrow Agent in writing that
aggregate Subscription Proceeds for Interests in such Partnership of $5,000,000
or more have been received and cleared by Escrow Agent, upon the written request
of MD, Escrow Agent shall disburse all or any portion of the Escrow Funds to an
account established by MD for the Partnership.

misconduct or gross negligence.

      All protections and indemnities benefitting the Escrow Agent (and any
other Indemnified Party) are cumulative of any other rights it (or they) may
have by law or otherwise, and shall survive the termination of the Escrow

NAVITAS INTERNATIONAL CORPORATION
4 Dublin Circle
Burlington, MA 01803

      Re: Navitas International Corporation

Dear Ladies and Gentlemen:

      This letter is being delivered to you in accordance with the Underwriting
Agreement (the "UNDERWRITING AGREEMENT") entered into by and between Navitas
International Corporation, a Delaware corporation (the "COMPANY"), and FTN
Midwest Securities Corp., as Representative (the "REPRESENTATIVE") of the
Underwriters named in Schedule I thereto (the "UNDERWRITERS"), relating to an
underwritten initial public offering (the "IPO") of the Company's units (the
"UNITS"), each comprised of one share of the Company's common stock, par value
$0.0001 per share (the "COMMON STOCK"), and two warrants, each being exercisable
for one share of Common Stock. The capitalized terms set forth on Schedule I
attached hereto are hereby incorporated by reference herein.

      In order to induce the Company and the Underwriters to enter into the
Underwriting Agreement and to proceed with the IPO, and in recognition of the
benefit that such IPO will confer upon the undersigned individual named below
(the "UNDERSIGNED") as a stockholder of the Company, and for other good and
valuable consideration, the receipt and sufficiency of which are hereby
acknowledged, the Undersigned hereby agrees as follows:

1. Until a Business Combination is consummated by the Company, the undersigned
agrees to vote all Insider Shares beneficially owned by him in accordance with
the majority of the votes cast by the holders of the IPO Shares in connection
with the vote by the Company's stockholders relating to the approval of any
Business Combination.

2. If a Transaction Failure occurs, the Undersigned shall take all reasonable
actions to cause the Company to dissolve and liquidate and vote all Insider
Shares and IPO Shares, if any, in favor of Company's dissolution and
liquidation.

3. The Undersigned hereby waives any and all right, title, interest or claim of
any kind in or to any distribution of the Trust Fund or against the Trustees
("CLAIM") with respect to the Undersigned's Insider Shares, and hereby waives
any Claim the Undersigned may have in the future as a result of, or arising out
of, any contracts or agreements with the Company and will not seek recourse for
any Claim against the Trust Fund or the Trustees for any reason whatsoever.
Without limiting the foregoing, the

<PAGE>

Undersigned acknowledges that he or she does not have a Claim arising out of and
waives any Claim it may have in the future as a result of (i) the promissory
note by the Company in favor of the Undersigned and (ii) the indemnification
agreement by and between the Company and the Undersigned. The Undersigned hereby
agrees that the Company shall be entitled to a reimbursement from the
Undersigned for any distribution of the Trust Fund received by the Undersigned
in respect to such person's Insider Shares.

4. [For Officers of the Company] Upon a Transaction Failure, the Undersigned
agrees to indemnify and hold harmless the Company, jointly and severally with
the other Indemnifiers, against any and all losses, liabilities, claims, damages
and expenses whatsoever (including, but not limited to, any and all legal or
other expenses reasonably incurred in investigating, preparing or defending
against any litigation, whether pending or threatened, or any claim whatsoever)
(collectively, "DAMAGES") to which the Company may become subject as a result of
any claim by (x) any vendor or other person who is owed money by the Company for
services rendered or products sold, or (y) any target business with which the
Company has entered into a written letter of intent, confidentiality or
non-disclosure agreement or other written agreement, except that no such
indemnification obligation shall apply to any Damages with respect to or arising
out of any claims made by a vendor, other person or target business that has
signed a valid and enforceable release, waiver or similar agreement (whether as
part of such written agreement or otherwise) waiving any right, title, interest
or claim of any kind in or to any amounts held in the Trust Fund; provided,
however, that the amount of any such indemnification obligation shall be limited
to the amount by which such Damages (i) actually reduce the amount of funds in
the Trust Fund and (ii) are not reimbursed by any insurance procured by the
Company to cover such claims made against the Trust Fund. It is hereby
acknowledged and agreed that if the Undersigned is removed or ceases to be an
officer of the Company, then his indemnification obligations shall apply only to
claims with respect to or arising out of acts or omissions by the Company during
his tenure as an officer of the Company.

5. If the Undersigned is not an officer of the Company, neither the Undersigned
nor any member of the family of the Undersigned or any Affiliate of the
Undersigned will be entitled to receive and will not accept any finder's fee or
any other compensation for services rendered to the Company prior to or in
connection with the consummation of the Business Combination. The Undersigned
shall be entitled to reimbursement from the Company for his or her reasonable
out-of-pocket expenses incurred in connection with seeking and consummating a
Business Combination. Until the consummation of the Business Combination, the
Undersigned shall not be a director, officer or employee of, or act as an
independent contractor or consultant for or to, any other blank check company.
If the Undersigned is an officer of the Company, upon the consummation of the
IPO, the Undersigned will become a full-time employee of the Company and will
receive annual compensation as determined in the discretion and good faith
judgment of the independent members of the board of directors.

6. The Undersigned will escrow his Insider Shares in accordance with the terms
of a stock escrow agreement which the Company will enter into with the
Undersigned and Continental Stock Transfer & Trust Company, as escrow agent, in
form and substance acceptable to the Company and the Representative.

<PAGE>

8. The Undersigned has full right and power, without violating any agreement by
which he or she is bound (including, without limitation, any non-competition or
non-solicitation agreement with any employer or former employer), to enter into
this letter agreement and to serve as [position] of the Company.

9. The Undersigned authorizes any employer, financial institution or consumer
credit reporting agency to release to the Representative, its legal
representative and any investigative search firm retained by the Representative
any information they may have about the Undersigned's background and finances
("INFORMATION"), solely for the purposes of the IPO. Neither the Representative,
its legal representative or any investigative search firm retained by the
Representative shall be violating the Undersigned's right of privacy in any
manner in requesting and obtaining the Information and the Undersigned hereby
releases them from liability for any damage whatsoever in that connection. The
Undersigned shall be entitled to a copy of such Information, upon request. The
Representative shall not release such Information to the Company or to any
third-party, other than the Representative's legal representative, without the
prior written consent of the Undersigned. The Representative shall use the same
measures to protect the Information as it takes to protect its own similar
confidential information, but in no event less than reasonable care.

10. Until the earlier of the consummation of the Business Combination or the
Termination Date, the Undersigned agrees to present to the Company for its
consideration, prior to presentation to any other person or company, any
suitable opportunity to acquire all or substantially all of the outstanding
equity securities or assets of, or otherwise acquire a controlling interest in,
whether by merger, capital stock exchange, asset acquisition, stock purchase or
any other similar type of combination, an operating business in India focused
primarily on product companies in industries well positioned to grow as a result
of the massive and ongoing development of the Indian infrastructure.

11. The Undersigned agrees not to acquire any IPO Shares prior to the completion
of the Business Combination.

respective successors, heirs, personal representatives and assigns. This letter

and (ii) the Termination Date.

13. This letter agreement shall be governed by and interpreted and construed in
accordance with the laws of the Commonwealth of Massachusetts applicable to
contracts formed and to be performed entirely within the Commonwealth of
Massachusetts, without regard to the conflicts of law provisions thereof to the
extent such principles or rules would require or permit the application of the
laws of another jurisdiction.

14. The Undersigned hereby agrees that any action, proceeding or claim against
it arising out of or relating in any way to this letter agreement shall be
brought and enforced in any state or federal court sitting in the Commonwealth
of Massachusetts (each, a

<PAGE>

"MASSACHUSETTS COURT"), and irrevocably submits to such jurisdiction, which
jurisdiction shall be exclusive. The Undersigned hereby waives any objection to
such exclusive jurisdiction and that such courts represent an inconvenient
forum. [For N.L. Jain and G.N. Bajpai] [The Undersigned has appointed Servjeet
S. Bhachu, in his capacity as General Counsel and Vice President of the Company,
as his authorized agent (the "AUTHORIZED AGENT") upon whom process may be served
in any such action arising out of or based on this Agreement or the transactions
contemplated hereby which may be instituted in any Massachusetts Court. Such
appointment shall be irrevocable. The Company and the Undersigned represent and
warrant that the Authorized Agent has agreed to act as such agent for service of
process and agrees to take any and all action, including the filing of any and
all documents and instruments that may be necessary to continue such appointment
in full force and effect as aforesaid. Service of process upon the Authorized
Agent and written notice of such service to the Company shall be deemed, in
every respect, effective service of process upon the Undersigned.]

15. No term or provision of this letter agreement may be amended, changed,
waived, altered or modified except by written instrument executed and delivered
by each of the Undersigned and the Company and the consent of the
Representative, which consent shall not be unreasonably withheld.
