                        WARRANTS TO PURCHASE COMMON STOCK                NO. __

     MICROTEL INTERNATIONAL, INC., a Delaware corporation (the "Company") hereby
grants to ______________________________________________________ (the "Holder")
_________________________ (____) non-transferable warrants (the "Warrants") for
the purchase of common stock of the Company (the "Common Stock"), with each
whole Warrant entitling the Holder to purchase one share of Common Stock (each a
"Warrant Share" and collectively the "Warrant Shares") on the terms and subject
to the conditions set forth herein.

     1.   TERM. The Warrants may be exercised, in whole or in part, at any time
and from time to time from the date hereof until 5:00 Pacific Time on December
31, 2003 (the "Exercise Period").

     2.   EXERCISE PRICE. The initial exercise price of each whole Warrant shall
be $0.65625 (the "Exercise Price"). The Exercise Price shall be subject to
adjustment as provided in Section 9.

     3.   EXERCISE OF WARRANTS. The Warrants are exercisable on the terms
provided herein at any time during the Exercise Period by the surrender of this
certificate to the Company at its principal office together with the Notice of
Exercise annexed hereto duly completed and executed on behalf of the Holder,
accompanied by payment in full, in immediately available funds, of the amount of
the aggregate Exercise Price of the Warrant Shares being purchased upon such
exercise. The Holder shall be deemed the record owner of such Warrant Shares as
of and from the close of business on the date on which this certificate is
surrendered together with the completed Notice of Exercise and payment in full
as required above (the "Exercise Date"). In the event the Holder exercises less
than all of the Warrants, the Company shall, concurrent with the issuance of
that portion of the Warrant Shares issuable upon such exercise, issue to Holder
new warrants in an amount equal to the remaining unexercised Warrants. The
Holder shall be deemed

                                      -1-

<PAGE>

the record owner of such Warrant Shares as of and from the close of business on
the date on which this certificate is surrendered together with the completed
Notice of Exercise and payment in full as required above (" the Exercise date").
The Company agrees that the Warrant Shares so purchased shall be issued as soon
as practicable thereafter.

     4.   FRACTIONAL INTEREST. In lieu of issuing fractional shares of Common
Stock upon exercise of the Warrants, the Company may pay the Holder a cash
amount determined by multiplying the fraction of a share otherwise issuable by
the Fair Market Value of one share of Common Stock. For this purpose, "Fair
Market Value" means the average closing sale price for the ten trading days
immediately preceding the Exercise Date or, if there is no last-sale reporting
for the Common Stock at such time, then the value as determined in good faith by
the Board of Directors of the Company.

     5.   WARRANTS CONFER NO RIGHTS OF STOCKHOLDER. The Holder shall not have
any rights as a stockholder of the Company with regard to the Warrant Shares
prior to the Exercise Date for any actual purchase of Warrant Shares.

     6.   INVESTMENT REPRESENTATION. Neither the Warrants nor the Warrant Shares
issuable upon the exercise of the Warrants have been registered under the
Securities Act or any state securities laws. The Holder acknowledges by
acceptance of this certificate that, as of the date of this Warrant and at the
time of exercise, (a) the Holder has acquired the Warrants or the Warrant
Shares, as the case may be, for investment and not with a view to distribution;
and either (b) the Holder has a pre-existing personal or business relationship
with the Company or its executive officers, or by reason of the Holder's
business or financial experience the Holder has the capacity to protect the
Holder's own interests in connection with the transaction; and (c) the Holder is
an accredited investor as that term is defined in Rule 501(a) of Regulation D
under the Securities Act. The Holder agrees, by acceptance of this certificate,
that any Warrant Shares purchased upon exercise of the Warrants may have to be
held indefinitely, until registered and qualified for resale pursuant to Section
8, or until an exemption from registration is available, as evidenced by an
opinion of counsel reasonably satisfactory to the Company. The Holder, by
acceptance of this certificate, consents to the placement of a restrictive
legend (the "Legend") on the certificates representing any Warrant Shares that
are purchased upon exercise of the Warrants during the applicable restricted
period under Regulation S or any other applicable restricted period under the
Securities Act. The Legend shall be in substantially the following form:

     THE SECURITIES REPRESENTED BY THIS CERTIFICATE (THE "SHARES") HAVE NOT BEEN
     REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE "SECURITIES
     ACT"), OR UNDER ANY STATE SECURITIES LAWS ("STATE LAWS") OR ANY SECURITIES
     LAWS OF JURISDICTIONS OUTSIDE OF THE UNITED STATES, AND MAY NOT BE OFFERED,
     SOLD, PLEDGED OR OTHERWISE TRANSFERRED IN THE UNITED STATES OR TO A "U.S.
     PERSON," AS THAT TERM IS DEFINED IN REGULATION S UNDER THE SECURITIES ACT,
     EXCEPT (1) PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT FILED UNDER THE
     SECURITIES ACT COVERING THE SECURITIES, OR (2) UPON DELIVERY TO THE COMPANY
     OF AN OPINION OF U.S. COUNSEL REASONABLY SATISFACTORY TO THE COMPANY THAT
     THE SECURITIES MAY BE TRANSFERRED WITHOUT REGISTRATION PURSUANT TO (A) RULE
     144, RULE A, OR RULE 904 OF REGULATION S PROMULGATED UNDER THE

                                      -2-

<PAGE>

     SECURITIES ACT OR (B) ANY OTHER AVAILABLE EXEMPTION FROM THE REGISTRATION
     AND PROSPECTUS DELIVERY REQUIREMENTS OF THE SECURITIES ACT.

     7.   REGISTRATION RIGHTS. The Company shall have no obligation to register
the Warrant Shares under the Securities Act of 1933, as amended (the "Securities
Act") in a separate registration statement with the Securities and Exchange
Commission (the "SEC") and accordingly, the Warrant Shares shall constitute
"restricted securities" for purposes of the Securities Act and Holder will not
be able to transfer such Shares except upon compliance with the registration
requirements of the Securities Act and applicable state securities laws or an
exception therefrom and the certificate(s) evidencing the Warrant Shares to be
issued shall contain a legend to the foregoing effect. Notwithstanding the
foregoing, the Company shall grant to Holder "piggy-back" registration rights so
as to include the Warrant Shares in any applicable registration statement filed
by the Company with the SEC at any time during the one (1) year period following
the issuance of the Warrant Shares.

     8.   RESERVATION OF SHARES. The Company agrees that, at all times during
the Exercise Period, the Company will have authorized and reserved, for the
exclusive purpose of issuance and delivery upon exercise of the Warrants, a
sufficient number of shares of its Common Stock to provide for the issuance of
the Warrant Shares and upon issue such sahres shall be fully paid and
non-assessable.

     9.   ADJUSTMENT FOR CHANGES IN CAPITAL STOCK. If the Company at any time
during the Exercise Period shall, by subdivision, combination or
reclassification of securities, change any of the securities into which the
Warrants are exercisable into the same or a different number of securities of
any class or classes, the Warrants shall thereafter entitle the Holder to
acquire such number and kind of securities as would have been issuable as a
result of such change with respect to the Warrant Shares if the Warrant Shares
had been outstanding immediately prior to such subdivision, combination, or
reclassification. If shares of the Company's Common Stock are subdivided into a
greater number of shares of Common Stock, the Exercise Price for the Warrant
Shares upon exercise of the Warrants shall be proportionately reduced and the
number of Warrant Shares shall be proportionately increased; and conversely, if
shares of the Company's Common Stock are combined into a smaller number of
shares of Common Stock, the Exercise Price shall be proportionately increased,
and the number of Warrant Shares shall be proportionately decreased.

     10.  LOSS, THEFT, DESTRUCTION OR MUTILATION OF CERTIFICATE. Upon receipt by
the Company of evidence reasonably satisfactory to it of the loss, theft,
destruction or mutilation of any certificate representing the Warrants or the
Warrant Shares (referred to herein as the "original certificate"), and in case
of loss, theft or destruction, of indemnity or security reasonably satisfactory
to the Company, and upon reimbursement to the Company of all reasonable expenses
incidental thereto, and upon surrender and cancellation of the original
certificate if mutilated, the Company will make and deliver a new certificate of
like tenor in lieu of the original certificate.

     11.  ASSIGNMENT. The Warrants are fully transferable subject only to
applicable securities laws.
