     Four M International, Inc., a company organized under the laws of Barbados
("Four M") was organized for the purpose of acquiring and holding shares of
stock in the Issuer.  Four M's principal executive offices are located c/o 1980
Post Oak Boulevard, #1850, Houston, Texas 77056.

     The directors of Four M are Henry Toh and Abe Dunn, both of whom are
citizens of the United States, and both of whom disclaim beneficial ownership
of the shares described herein.

     None of Four M or any of its executive officers and directors have been

Convertible Preferred Stock, $10.00 par value per share ("Preferred Stock"),
pursuant to a Stock Purchase Agreement, dated February 19, 1992, by and among

160,000 shares of Preferred Stock and the source of such funds was the working
capital of Four M.

to the Registration Statement.  

Item 5.  Interest in Securities of the Issuer

     (a)  The 160,000 shares of Preferred Stock were converted to an aggregate
of 3,915,570 shares of Common Stock on June 28, 1996.  Thereafter, in accordance
with transactions described in Item 6 hereof, an aggregate of 1,960,332 shares
of such Common Stock have been sold, so that as of the date hereof Four M owns
an aggregate of 1,955,238 shares of Common Stock, 1,753,758 shares of which are
subject to the terms of the options described in Item 6 hereof. 

     (b)  Four M has the sole power to vote or direct the vote of an aggregate

and sole power to dispose or to direct the disposition of  1,753,758 shares
owned subject to options as described in Item 6.

     (c)  As described in Item 6, Four M granted certain options to purchase
shares to certain parties who are not affiliates of Four M.  On December 31,
1996 options to purchase an aggregate of 142,738 shares of Common Stock owned
by Four M were exercised at an exercise price of $1.79 per share; in July 1997
options to purchase an additional 250,000 shares of Common Stock were exercised
at an exercise price of $2.35 per share; in August 1997 options to purchase

share; in September 1997 options to purchase an additional 783,568 shares were
exercised at an exercise price of $2.54 per share and options to purchase an
aggregate of 441,480 shares expired; in October 1997 options to purchase an
additional 10,000 shares were exercised at an exercise price of $1.79 per
share; and in November 1997 options to purchase an additional 193,917 were
exercised at an exercise price of $1.79 per share.  An additional 170,000
shares were sold in October 1997 and 70,000 shares were sold in November 1997
pursuant to the Registration Statement.

     (d)  No person has the right to receive or the power to direct the receipt
of dividends from, or the proceeds from the sale of, any of the shares of Common
Stock owned of record by Four M.

     (e)  Not applicable.   

Item 6.  Contracts, Arrangements, Understandings or Relationships with Respect
to Securities of the Issuer

     On February 21, 1996, Four M granted certain options to purchase shares 
of the Company owned by Four M exercisable commencing July 1, 1996 (subject to
the satisfaction of certain conditions) to purchase 3,915,570 shares of Common
Stock.  Henry Y.L. Toh, a director of the Issuer, is one of the two 
  Page 4 of 15
directors of Four M.  The exercise price of $1.79 per share represents the
lesser of 200% of the average of the closing bid and ask price per share of
Common Stock for the ten (10) business days preceding July 1, 1996 or $1.79
per share.  Commonwealth Associates and affiliates or associates thereof
received the right to purchase 545,285 shares of Common Stock prior to
December 31, 1996 and 537,500 shares of Common Stock prior to December 31,
1997.  Benchmark Equity Group, Inc. received the right to purchase 545,285
shares of Common Stock prior to December 31, 1996 and 537,500 shares prior to
December 1997.  Certain members of the then management of I-Link Worldwide,
Inc., namely, Clay Wilkes, Floyd Wilkes and Alex Radulovic, received the right
to purchase an aggregate of 825,000 shares of Common Stock prior to December
31, 1996 and 825,000 shares prior to December 31, 1997.  Scott Cook received
the right to purchase 100,000 shares prior to December 31, 1996.  On April 24,
1996, the Four M Options issued to Mr. Cook were canceled and options were
issued as of that date by Four M to Mr. Cook (50,000 shares), S.C. Culbreth
(25,000 shares) and John Beardmore (25,000 shares).

     In August 1996 the Four M Options were amended to provide that in the
event that $200,000 in principal amount (i.e., exercise proceeds) of the Four
M Options have been exercised prior to December 31, 1996, the exercise period
of the remaining Four M Options exercisable during 1996 (the "1996 Four M
Options") would be extended to September 6, 1997 and the exercise price would
be increased by four percent (4%) of the then current exercise price for each
30 day period or portion thereof commencing January 1, 1997 in which the
remainder of the 1996 Four M Options are not exercised.  Inasmuch as the
aggregate amount exercised exceeded $200,000 in principal amount, the exercise
period of the remaining Four M Options was extended to September 6, 1997.

     Thereafter, certain of such option holders exercised and/or transferred
portions of such options, so that options exercisable until December 31, 1997,
at $1.79 are held, to the best knowledge and belief of Four M, as of November
30, 1997, as follows:  William Baquet, 240,696 shares; C. Giordano, 10,000
shares; Phyllis Henderson, 20,000 shares; Commonwealth Associates, 231,779
shares; Clay Wilkes, 389,891 shares; Alex Radulovic, 250,000 shares; Floyd
Wilkes, 185,000 shares; Scott Cook, 25,000 shares; John Beardsmore, 12,500
shares; R.C. Culbreth, 12,500 shares; Benchmark Equity Group, 356,382 shares;
and Carl Shaifer, 20,000 shares.

  Re:  Option to Acquire Class A Preferred Stock of Medcross, Inc. ("Medcross")

Gentlemen:

     Four M International, Ltd. ("Four M") is the owner of 160,000 shares of 
Class A Convertible Preferred Stock of Medcross (the "Preferred Stock") and
desires to grant to [name of option holder "Option Holder"] an option to
acquire the shares of common stock issuable upon conversion of shares of the
Preferred Stock (the "Common Stock") at an exercise price equal to the lesser
of: (i) 200% of the average of the closing bid and asked prices per share of
the Common Stock as quoted on the Nasdaq SmallCap Market  for the ten days
preceding the initial exercise date set forth below, or (ii) $1.79 per share 
the (the "Exercise Price").  In light of the foregoing, this letter is intended
to set forth the basic terms and conditions of the grant of such option.  
Counter-execution below by you shall constitute the agreement, acknowledgement
and acceptance by Option Holder of the terms and conditions set forth herein.

     1.   Grant of Option.  Four M hereby grants to Option Holder, subject to 
the terms and conditions set forth herein, an option to acquire up to __________
shares of Common Stock issuable upon conversion of the Preferred Stock owned by
Four M at the Exercise Price as set forth above.  Such option shall become
exercisable on July 1, 1996, subject to Section 2 below, and shall be exercised
by delivery of written notice to Four M of Option Holder's desire to exercise
all or a portion of the option granted herein (to the extent the same has
become exercisable as set forth in Section 2 below).  Upon execution hereof,
Four M shall cause the shares of Preferred Stock to be converted into an
aggregate of _______ shares of Common Stock.  Upon exercise of the option
granted herein, Four M shall transfer, deliver and surrender to Option Holder
certificates representing all of the shares of Common Stock issuable upon such
exercise.  Each such certificate shall be properly endorsed in blank or 
accompanied by a fully executed stock power relating thereto, or new 
certificates representing the shares of Common Stock shall be issued in the 
name of Option Holder.  Concurrent with delivery of such certificates to Option
Holder, Option Holder shall deliver via wire transfer of immediately available
funds an aggregate amount equal to the exercise price attributable to the

     2.   Option Term; Expiration.  The option granted herein shall be 
exercisable through the close of business on December 31, 1997 to purchase up 
to _________ shares of Common Stock; provided, however, that Option Holder must
exercise its right to acquire an aggregate of ________ shares of such Common
Stock on or before the close of business on December 31, 1996.  In the event
that Option Holder fails to exercise its right to acquire the foregoing shares
of Common Stock on or before the close of business on December 31, 1996, Option
Holder's right to acquire such shares of Common Stock shall expire unexercised
and Option Holder shall thereafter retain only the right to acquire the 
remaining ________ shares of Common Stock subject hereto through the close of 
business on December 31, 1997, at which time the option granted herein shall
expire altogether if not previously exercised.

     3.   Representations and Warranties of Four M.  Four M hereby represents
and warrants to Option Holder as follows:

          (a)  Authorization.  Four M has taken all steps necessary and has all
the necessary corporate power to enter into this letter agreement, to grant the
option described herein and to consummate the transactions contemplated hereby.
This letter agreement has been duly and validly executed and delivered by Four
M and is the valid and binding obligation of Four M, enforceable against it in
accordance with its terms, except as such enforcement may be limited by
applicable bankruptcy, insolvency, reorganization, moratorium or other similar 
laws now or hereafter in effect, or by legal or equitable principles, relating
to or limiting creditors' rights generally and except that the remedy of
specific performance and injunctive and other forms of equitable relief are
subject to certain equitable defenses and to the discretion of the court before
which any proceeding therefor may be brought.

          (b)  Capitalization.  The number of shares of Preferred Stock owned 
by Four M as of the date hereof is as set forth herein.  The shares of Preferred
Stock owned by Four M, to the best knowledge of Four M, have been duly 
authorized, validly issued and are fully paid and nonassessable.  Four M is the
sole legal and beneficial owner of the foregoing shares of Preferred Stock. 
All of such shares of Preferred Stock are owned free of preemptive rights and
free and clear of all claims, liens, pledges, mortgages, charges, security
interests, encumbrances and other restrictions and/or limitations of any kind
whatsoever.  The acquisition of the Preferred Stock by Four M was for such
member's own account and was not with a view toward distribution or resale 
thereof.  

          (c)  Agreements; Actions.  Neither execution and delivery of this 
letter agreement nor consummation of the transactions contemplated hereby will
constitute or cause a violation or breach of any provision of any document,
agreement, contract or understanding to which Four M is a party or by which 
Four M is bound.  There is no action, suit, proceeding or investigation pending 
or threatened which could restrict the ability of Four M to perform its 
obligations hereunder and there are no grounds for or facts, events or 
circumstances which could form the basis of any such action that could cause
or result in any such 
  Page 8 of 15
[Name of Option Holder]
February 21, 1996
Page 9


action, suit, proceeding or investigation or which is probable of assertion. 
Four M is not in default in respect of any judgment, order, writ, injunction 
or decree of any court or any federal, state, local or other governmental
agency, authority, body, board, bureau, commission, department or 
instrumentality, and execution and delivery of this letter agreement and 
consummation of the transactions contemplated hereby will not constitute or 
cause a violation, breach or default of or under any of the foregoing.

     4.   Representations and Warranties of Option Holder.  Option Holder 
hereby represents and warrants to Four M as follows:

          (a)  Authorization.  Option Holder has taken all steps necessary and 
has all the necessary power to enter into this letter agreement, to receive the
option granted herein and to consummate the transactions contemplated hereby.
This letter agreement has been duly and validly executed and delivered by 
Option Holder and is the valid and binding obligation of Option Holder, 
enforceable against it in accordance with its terms, except as such enforcement
may be limited by applicable bankruptcy, insolvency, reorganization, moratorium
or other similar laws now or hereafter in effect, or by legal or equitable 
principles, relating to or limiting creditors' rights generally and except that
the remedy of specific performance and injunctive and other forms of equitable
relief are subject to certain equitable defenses and to the discretion of the
court before which any proceeding therefor may be brought.

          (b)  General Investment Representations.  Option Holder
understands that:  (i) the Preferred Stock (and the Common Stock issuable upon
conversion thereof) has not been the subject of registration under the
Securities Act of 1933 (the "1933 Act"), the federal securities laws or the
laws of any state; (ii) absent an exemption from registration under such laws,
the issuance and sale of the Preferred Stock (and the shares of Common Stock
issuable upon conversion thereof) would require registration; and (iii) the
transactions contemplated hereby are being undertaken in reliance upon 
exemption from the registration requirements of the 1933 Act.

          (c)  Agreements; Actions.  Neither execution and delivery of this
letter agreement nor consummation of the transactions contemplated hereby will
constitute or cause a violation or breach of any provision of any document, 
agreement, contract or understanding to which Option Holder is a party or by
which Option Holder is bound.  There is no action, suit, proceeding or 
investigation pending or threatened which could restrict the ability of Option
Holder to perform its obligations hereunder and there are no grounds for or
facts, events or circumstances which could form the basis of any such action 
that could cause or result in any such action, suit, proceeding or investigation
or which is probable of assertion.  Option Holder is not in default in respect
of any judgment, order, writ, injunction or decree of any court or any federal, 
state, local or other governmental agency, authority, body, board, bureau, 
commission, department or instrumentality, and execution and delivery of this 
letter agreement and consummation of the transactions

of or under any of the foregoing.

     5.   Registration.  Medcross shall prepare and file or cause to be 
prepared and filed, at itsexpense and as soon as practicable after execution 
hereof (but in no event later than 90 days thereafter), a registration 
statement under the Securities Act of 1933 with the Securities and Exchange 
Commission (the "SEC") relating to the reoffer and resale of the shares of 
Common Stock subject hereto and shall use its best efforts to cause the same

declaration of effectiveness by the SEC.  In the event that Medcross shall
fail to file the foregoing registration statement with the time set forth 
above, it shall include for registration the shares of Common Stock subject 
hereto in the first registration statement filed by Medcross thereafter.  
Notwithstanding the foregoing, in the event that Medcross determines to 
register the offer and sale of any of its securities pursuant to an underwritten
offering and the underwriter thereof so requests, Option Holder hereby agrees to
refrain from selling the securities subject hereto for a period of up to twelve 
months from the date of effectiveness of any such registration statement.

agreement and for all matters relating to consummation of the transactions

execution of this letter or consummation of the transactions contemplated
hereby.  The parties hereto hereby agree to indemnify one another against the
claims of any broker or finder who claims through any of the parties as an
indemnifying party hereunder.

 Re:  Amendment to Option to Acquire Class A Preferred Stock of Medcross, Inc.

Gentlemen:

     On or about February 21, 1996 Four M International, Ltd. ("Four M") 
granted options (the "Four M Options") to purchase an aggregate of 3,915,570
shares of Common Stock of Medcross, Inc. ("Medcross") to Commonwealth 
Associates and certain affiliates or associates thereof, members of management
of ILINK and Benchmark, including options held by you (collectively, the "Four
M Optionholders").  Of such Four M Options, options to purchase an aggregate of
2,011,678 shares are exercisable from July 1, 1996 through December 31, 1996 
(the "1996 Four M Options") and options to purchase an aggregate of 1,903,892
shares are exercisable from July 1, 1996 through December 31, 1997.  This 
letter is intended to set forth our understanding of the modification of 
certain of the terms and conditions of such Four M Options, including the terms
of the Four M Option held by you.   
     
     In consideration of the sum of $10.00 and other good and valuable 
consideration, the receipt and sufficiency of which is acknowledged, the Four 
M Option heretofore granted to you is hereby amended as follows:

     In the event that $200,000 in principal amount (i.e., exercise proceeds)
of the Four M Options have been exercised prior to December 31, 1996 (the 
"Partial Exercise"), the exercise period relating to the remaining 1996 Four M
Options will be extended to a date which is twelve (12) months from the final
closing of the Medcross private offering of Class C Preferred Stock.  In 
addition, in the event of such Partial Exercise, for every thirty (30) day 
period or portion thereof commencing January 1, 1997 in which the remainder of
the 1996 Four M Options are not exercised, the minimum exercise price of the
1996 Four M Options (presently $1.79 per share) shall be increased by four 
percent (4%) of the then current exercise price.  In the event of such 
extension, it is our understanding that the 1996 Four M Options shall be 
exercisable at the following prices:
