THE WARRANTS REPRESENTED BY THIS CERTIFICATE ("WARRANTS") AND THE UNDERLYING
WARRANT SHARES ("WARRANT SHARES") HAVE NOT BEEN REGISTERED UNDER THE SECURITIES
ACT OF 1933, AS AMENDED (THE "SECURITIES ACT"). THE WARRANTS MAY NOT BE
EXERCISED OFFERED OR SOLD UNLESS, IN EACH CASE, THE WARRANTS AND WARRANT SHARES
HAVE BEEN REGISTERED UNDER THE SECURITIES ACT OR AN EXEMPTION FROM SUCH
REGISTRATION IS AVAILABLE, AS EVIDENCED BY AN OPINION OF COUNSEL REASONABLY
SATISFACTORY TO THE COMPANY.

THE WARRANTS REPRESENTED BY THIS CERTIFICATE MAY NOT BE TRANSFERRED, SOLD,
PLEDGED, HYPOTHECATED AND ENCUMBERED.

                        WARRANTS TO PURCHASE COMMON STOCK

     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 May 3,
2002 (the "Exercise Period").

     2.   EXERCISE PRICE. The initial exercise price of each whole Warrant shall
be $0.75 per share (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"). The Company agrees that the Warrant
Shares so purchased shall be issued as soon as practicable thereafter. It shall
be a condition to the exercise of the Warrants that the Holder or any transferee
hereof provide an opinion of counsel reasonably satisfactory to the Company that
the Warrants and the Warrant Shares to be delivered upon exercise thereof have
been registered under the Securities Act or that an exemption from the
registration requirements of the Securities Act is available.

<PAGE>

     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 Warrants
Shares issuable upon the exercise of the Warrants have been registered under the
Securities Act or any state securities laws. The Holder acknowledges by signing
this certificate that, as of the date of this Warrant and at the time of
exercise that: (a) the Holder has acquired the Warrant or the Warrant Shares, as
the case may be, for the Holder's own account; (b) 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 (c) either 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. 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 7, 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 Rule 144 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 HAVE NOT BEEN REGISTERED
     UNDER THE SECURITIES ACT OF 1933, AS AMENDED. SUCH SHARES HAVE BEEN
     ACQUIRED FOR INVESTMENT AND MAY NOT BE SOLD, TRANSFERRED, PLEDGED OR
     HYPOTHECATED IN THE ABSENCE OF AN EFFECTIVE REGISTRATION STATEMENT FOR SUCH
     SHARES UNDER THE SECURITIES ACT OF 1933, AS AMENDED, UNLESS IN THE WRITTEN
     LEGAL OPINION (APPROVED BY THE COMPANY) OF COUNSEL SATISFACTORY TO THE
     COMPANY, SUCH REGISTRATION IS NOT REQUIRED.

     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

<PAGE>

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.

     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.

     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 may not be transferred or assigned.

     12.  GENERAL. This certificate shall be governed by and construed in
accordance with the laws of the State of California applicable to contracts
between California residents entered into and to be performed entirely within
the State of California. The headings herein are for purposes of convenience and
reference only and shall not be used to construe or interpret the terms of this
certificate. The terms of this certificate may be amended, waived, discharged or
terminated only by a written instrument signed by both the Company and the
Holder. All notices and other communications from the Company to the Holder
shall be mailed by first-class registered or certified mail, postage pre-paid,
to the address furnished to the Company in writing by the last Holder who shall
have furnished an address to the Company in writing.

                                 CXR CORPORATION

                             1993 STOCK OPTION PLAN

1.       PURPOSE

         This 1993 Stock Option Plan (the "Plan") is intended to reward past
service by, increase incentive for and encourage stock ownership on the part of
selected key employees of, and independent contractors retained by, CXR
Corporation (the "Corporation") or other corporations which are or become
subsidiaries of the Corporation. It is also the purpose of the Plan to provide
such employees and independent contractors with a proprietary interest, or
increase their proprietary interest, in the Corporation and its subsidiaries,
and to encourage them to continue in the employ of or to be retained by the
Corporation or the subsidiaries. It is intended that certain options granted
pursuant to the Plan shall constitute incentive stock options ("incentive stock
options") within the meaning of Section 422 of the Internal Revenue Code of
1986, as amended (the "Code"), and that certain options granted pursuant to the
Plan shall not constitute incentive stock options ("non-qualified stock
options"). The word "subsidiaries" as used in the Plan shall mean corporations
in which the Corporation owns, directly or indirectly, 50 percent or more of the
voting stock, in accordance with Section 424(f) of the Code.

2.       STOCK

         The Stock subject to the Plan shall be the shares of the Corporation's
authorized but unissued common stock, $.0033 par value (the "Common Stock"). The
aggregate number of shares which may be issued under the Plan shall not exceed
1,500,000, subject to such adjustments as may be required pursuant to Section 6
hereof. In the event that any outstanding option under the Plan shall expire or
be terminated for any reason, the shares of the Common

<PAGE>

Stock allocated to the unexercised portion of such option shall again become
available to be made subject to an option under the Plan.

3.       ADMINISTRATION

         The Plan shall be administered by the Compensation Committee of the
Board of Directors of the Corporation (the "Board"). The Board shall be
authorized, subject to the provisions of the Plan, to establish such rules and
regulations as it may deem appropriate for the proper administration of the
Plan, and to make such determinations under, and such interpretations of, and to
take such steps in connection with, the Plan or the options granted thereunder
as it may deem necessary or advisable. The interpretation and construction by
the Board of any provisions of the Plan or any option granted pursuant thereto
shall be final, binding and conclusive. No member of the Board shall be liable
for any action, failure to act, determination or interpretation made in good
faith with respect to the Plan or any transaction thereunder.

         Notwithstanding the foregoing, the Board shall have the authority to
delegate its duty to administer the Plan to a committee of the Board appointed
by the Board. In addition, the Plan shall be administered in such manner as the
Board shall determine in order to assure that the Plan complies with Rule 16b-3
of the Securities and Exchange Commission ("Rule 16b-3") if the Board shall deem
such compliance necessary or desirable. Any committee charged with
administration of the Plan shall have all the powers and protections authorized
to the Board under the Plan, except those powers set forth in Section 14 hereof,
until the Board shall decide otherwise.

                                      -2-
<PAGE>

4.       ELIGIBILITY AND AWARD OF OPTIONS

         The Board shall have full and final authority in its discretion, at any
time and from time to time, to grant or authorize the granting of options to
such officers and other key employees of and independent contractors retained by
the Corporation or its subsidiaries, whether or not members of the Board, as it
may select, and for such numbers of shares as it shall designate. The Board
shall have full and final authority in its discretion to determine, in the case
of officers and other key employees, whether such options shall be incentive
stock options or nonqualified stock options and whether incentive stock options
and non-qualified stock options shall be awarded pursuant to separate grants or
in conjunction. To the extent that the aggregate fair market value (determined
as of the date on which the option is granted) of the Common Stock with respect
to which incentive stock options granted to an officer or other key employee are
exercisable for the first time by such individual during any calendar year
(under all incentive stock option plans of his or her employer corporation and
its parent and subsidiary corporations) exceeds $100,000, such options (taken
into account in the order in which they were granted) shall be treated as
non-qualified stock options. Persons selected by the Board who are prospective
employees of or independent contractors retained by the Corporation or its
subsidiaries shall be eligible to receive non-qualified stock options; provided,
however, that, in the case of prospective employees, such options shall be
subject to such persons' becoming employees of the Corporation or its
subsidiaries. All options granted under the Plan shall be subject to the
Corporation's receipt of adequate consideration in accordance with applicable
law.

         The date which an option shall be granted shall be the date of the
Board's authorization of such grant or such later date as may be determined by
the Board at the time such grant is authorized. Any individual may hold more
than one option.

                                      -3-

5.       TERMS AND CONDITIONS OF OPTIONS

         Stock options granted pursuant to the Plan shall be evidenced by
agreements in such form as the Board shall determine, which agreements shall
comply with the following terms and conditions:

         A.       OPTIONEE'S RETENTION OR EMPLOYMENT

                  Each option agreement shall state that it shall not be
construed as granting an optionee who is an independent contractor any right to
continued retention by or employment with, or an optionee who is or becomes an
employee any right to continued employment with, the Corporation or any
subsidiary and that, subject to any written retention or employment agreement
between the optionee and the Corporation or any subsidiary, such retention and
employment shall be terminable at will by the Corporation or such subsidiary.

         B.       NUMBER OF SHARES

                  Each option agreement shall state the number of shares of the
Common Stock to which the option pertains.

         C.       OPTION PRICE

                  Each option agreement shall state the option price per share,
which shall be not less than 100 percent of the fair market value of a share of
the Common Stock on the date the option is granted. Notwithstanding the
foregoing, the option price per share of an option granted to a person who, on
the date of such grant and in accordance with Section 424(d) of the Code, owns
stock possessing more than 10 percent of the total combined voting power of all
classes of stock of the Corporation (or of its parent or subsidiary corporation)
shall be not less than 110 percent of the fair market value of a share of the
Common Stock on the date the option is granted. Fair market value shall mean (i)
the closing price of the Common Stock quoted on any exchange on which the Common
Stock is listed, whichever is applicable, as published in the

                                      -4-
<PAGE>

Western Edition of THE WALL STREET JOURNAL for the date an option is granted
or, if no report is available for such date, for the next preceding date for
which such a report is available; or (ii) if the Common Stock is not traded
Over-The-Counter or on an exchange, the amount determined in good faith by
the Board for the date an option is granted by applying the rules and
principles of valuation set forth in Treasury Regulation Section 20.2031-2,
relating to the valuation of stocks for purposes of Section 2031 of the Code.

         D.       MEDIUM AND TIME OF PAYMENT

                  The option price shall be payable upon the exercise of an
option in legal tender of the United States (in cash or by certified check) or,
in the discretion of the Committee, shares of Common Stock, provided such shares
shall have been held by the Optionee for not less than six months prior to the
date of tender to the Company. Upon receipt of payment, the Corporation shall
promptly deliver to the optionee (or the person entitled to exercise the option)
a certificate or certificates for the shares of the Common Stock to which the
option pertains.

         E.       TERM AND EXERCISE OF OPTION

                  Each option shall state the time or times when it becomes
exercisable and, subject to the other provisions of the Plan, the time or times
when it expires, both of which provisions shall be determined by the Board. To
the extent that an option has become exercisable, it may be exercised in whole
or in such lesser amount as authorized by the option agreement. If exercised in
part, the unexercised portion of an option shall continue to be held by the
optionee and may thereafter be exercised a provided in the option agreement and
herein. Notwithstanding any other provision of the Plan, no option granted under
the Plan shall be exercisable after the expiration of ten (10) years from the
date of its grant, and no option granted under the Plan to a person who, on the
date of such grant and in accordance with Section 424(d) f the Code, owns stock
possessing more than 10 percent of the total combined voting power of all
classes of stock

                                      -5-
<PAGE>

of the Corporation (or of its parent or subsidiary corporation) shall be
exercisable after the expiration of five (5) years from the date of its grant.

         F.       TERMINATION OF EMPLOYMENT OR RETENTION

                  (i)      If an optionee who is an employee shall cease to be
employed, or an optionee who is an independent contractor shall cease to be
retained (other than to become an employee), by the Corporation and any of its
subsidiaries for any reason other than death or permanent and total disability,
his or her option may be exercised within a period, determined by the Board and
set forth in the relevant option agreement, not longer than three (3) months
after the date of such cessation of employment or retention, as the case may be,
but only to the extent such option was exercisable under the terms of such
option agreement on such date.

                  (ii)     If an optionee who is an employee shall cease to be
employed, or an optionee who is an independent contractor shall cease to be
retained, by the Corporation and any of its subsidiaries by reason of permanent
and total disability, his or her option may be exercised within a period,
determined by the Board and set forth in the relevant option agreement, not
longer than one (1) year after the date of such cessation of employment or
retention, as the case may be, but only to the extent such option was
exercisable under the terms of such option agreement on such date.

                  (iii)    If an optionee should die while in the employ of, or
while retained by, the Corporation or any subsidiary or within the period not
longer than three (3) months or one (1) year referred to above, whichever is
applicable, his or her option may be exercised, to the extent it was exercisable
under the terms of the relevant option agreement immediately prior to the
optionee's death, at any time within a period, determined by the Board and set
forth in such option agreement, not longer than one (1) year after the
optionee's death by the optionee's executors or administrators or the person or
persons to whom the option is transferred by will or

                                      -6-
<PAGE>

by the applicable laws of descent and distribution. No transfer of an option
by the optionee by will or by the applicable laws of descent and distribution
shall be effective unless the Corporation shall have been furnished with
written notice thereof, and such other evidence as the Board may deem
necessary to establish the validity of the transfer and the acceptance of the
transferee or transferees of the terms and conditions of the option, and to
establish compliance with any laws or regulations pertaining thereto.

                  Permanent and total disability shall mean an optionee's
inability to engage in any substantial gainful activity by reason of any
medically determinable physical or mental impairment which can be expected to
result in death or which has lasted or can be expected to last for a continuous
period of not less than twelve (12) months, in accordance with Section 22(e)(3)
of the Code.

         G.       OTHER PROVISIONS

                  The option agreements authorized under the Plan shall contain
such other provisions, including, without limitation, restrictions upon the
exercise of the option, restrictions on the transferability and/or right to
retain shares of the Common Stock received upon the exercise of options, and
restrictions required by any applicable securities laws, as the Board shall deem
advisable.

6.       CHANGES IN CAPITALIZATION, REORGANIZATIONS AND OTHER EVENTS

         Subject to any action by the stockholders of the Corporation required
by law, the number of shares of the Common Stock covered by the Plan and each
outstanding option, and the price per share thereof, shall be proportionately
adjusted for any increase or decrease in the number of issued and outstanding
shares of the Common Stock resulting from a subdivision or consolidation of
shares or the payment of a stock dividend (but only on the Common Stock) or

                                      -7-
<PAGE>

any other increase or decrease in the number of such shares effected without
the receipt of consideration by the Corporation; provided, however, that no
such adjustment shall result in the issuance of any fractional shares of the
Common Stock. The issuance of shares of the Common Stock upon the conversion
of convertible securities shall be treated as an issuance for which the
Corporation receives consideration for this purpose. Adjustments pursuant to
this paragraph shall be made by the Board, whose determinations shall be
final, binding and conclusive.

         A dissolution or liquidation of the Corporation, a merger or
consolidation in which the Corporation is not the surviving corporation or a
change in control of the Corporation shall affect each outstanding option in the
manner set forth in the applicable option agreement.

         The grant of an option pursuant to the Plan shall not affect in any way
the right or power of the Corporation to make adjustments, reclassifications,
reorganizations or changes in its capital or business structure or to merge,
consolidate, dissolve, liquidate, sell or transfer all or any part of its
business or assets.

7.       NONASSIGNABILITY

         No option granted under the Plan shall be assignable or transferable by
an optionee except by will or the laws of descent and distribution. An option
granted under the Plan shall be exercisable, during the optionee's lifetime,
only by the optionee.

8.       NO OBLIGATION TO EXERCISE OPTION

         The granting of an option shall impose no obligation upon the optionee
or a transferee of the optionee o exercise such option.

                                      -8-
<PAGE>

9.       RIGHTS AS A STOCKHOLDER

         An optionee or a transferee of an optionee shall have no rights as a
stockholder with respect to any shares of the Common Stock covered by his or her
option until the date of the issuance of a stock certificate to the optionee or
transferee for such shares. No adjustment shall be made for dividends (ordinary
or extraordinary, whether in cash, securities or other property) or
distributions or other rights for which the record date is prior to the date
such stock certificate is issued, except as provided in Section 6.

10.      MODIFICATION, EXTENSION AND RENEWAL OF OPTIONS

         Subject to the terms and conditions and within the limitations of the
