                 CLARITI TELECOMMUNICATIONS INTERNATIONAL, LTD.


               UNAUDITED PRO FORMA COMBINED FINANCIAL STATEMENT

Prior to November 1998, Chadwell Hall Holdings, Ltd. ("CHH") owned 
approximately 25% of GlobalFirst Holdings, Ltd. ("GlobalFirst").  In November 
1998, CHH acquired the remaining 75% majority interest in GlobalFirst held by 
other parties.  CHH entered this transaction in order to facilitate the 
subsequent sale of GlobalFirst to Clariti Telecommunications International, 
Ltd. ("Clariti") in December 1998.

The following unaudited pro forma combined financial statement is based on 
the historical financial statements of Clariti Telecommunications 
International, Ltd. ("Clariti") and GlobalFirst Holdings, Ltd. ("GlobalFirst") 
adjusted to give effect to the purchase by CHH of the 75% majority interest in 
GlobalFirst and the subsequent acquisition of GlobalFirst by Clariti. The 
unaudited pro forma combined financial statement gives effect to the 
acquisition of GlobalFirst by Clariti in a transaction to be accounted for as a 
reverse acquisition under the purchase method of accounting.  The pro forma 
adjustments are based upon preliminary allocations of purchase price and upon 
the assumptions described in the accompanying notes.  Actual allocations of 
purchase price are likely to be different from that reflected in this pro forma 
financial statement.  References in this document to data presented on a "pro 
forma basis" as of any date or for any period shall have the meaning set forth 
above with respect to such date or period.

The unaudited pro forma combined financial statement should be read in 
conjunction with the financial statements of GlobalFirst appearing elsewhere in 
this document. The unaudited pro forma combined financial statement is 
presented for information purposes only and is not necessarily indicative of 
the results that would have been reported had such events occurred on the dates 
specified, nor is it indicative of Clariti's future results.

NOTES TO UNAUDITED PRO FORMA COMBINED STATEMENT OF OPERATIONS
--------------------------------------------------------------
(a) The Unaudited Pro Forma Combined Statement of Operations has been 
    prepared to reflect the December 1998 business combination between 
    Clariti and GlobalFirst as a reverse acquisition in which GlobalFirst is 
    considered the acquiror and Clariti is considered the acquired company. 
    Under the terms of the transaction, Clariti acquired 100% of the capital 
    stock of GlobalFirst in exchange for 76,571,500 shares of Clariti common 
    stock.  In conjunction with the acquisition, GlobalFirst's parent company, 
    Chadwell Hall Holdings, Ltd. ("CHH") and an affiliated company, Corporate 
    and Legal Nominees, Ltd., combined to purchase a total of 11,428,500 shares 
    of Clariti's restricted common stock for $20,000,000.  

    Additionally, the Unaudited Pro Forma Combined Statement of Operations
    reflects the November 1998 acquisition of the 75% majority interest in 
    Global First by CHH, for consideration which approximated $100 million.

(b) Pro forma adjustment reflects amortization of intangible assets resulting
    from the acquisitions on a straight-line basis over a useful life of five 
    years. Management has not yet allocated any of the excess purchase price of 
    either acquisition to identifiable intangible assets such as technology, 
    in-process research and development, or goodwill, as final valuations of 
    any potential intangible assets are not currently available. Appropriate 
    revisions will be made when the final valuations are available.  The useful 
    life of any individual asset so identified may differ from the five-year 
    amortization period reflected in this Pro Forma Combined Statement of 
    Operations.
