Six Months Ended December 31, 2004,  Compared with Six Months Ended December 31,
2003

During the first six months of Fiscal 2005, the Company's revenue grew 30% to
$123,235, compared to $94,860 in revenue for the similar period of Fiscal 2004.
During the current period the Company's sales resulted primarily from inquiries
generated by our web site. The Company intends to increase its selling effort
during the second half of fiscal 2005, as the GearDeck product line is
introduced.

Cost of revenue for the six months ended December 31, 2004, increased $10,753 or
24% from $44,961 during the 2003 period, to $55,714 for the 2004 period.

Gross margin on product sales increased to 55% for the current period from 53%
during last years comparable period.

                                        6


SG&A expenses increased to $229,466 for the six months ended December 31, 2004,
compared to $145,911 for the comparable period of 2003. The increase in SG&A
expenses for the current six month period is primarily attributable to costs
associated with the Tenet Information Services combination.

Net loss for the six months ended December 31, 2004, was ($159,494) or ($0.02)
per share as compared to ($232,166) or ($0.07) per share for the six months
ending December 31, 2003.

LIQUIDITY AND CAPITAL RESOURCES

The Company's cash position increased from $6,895 at December 31, 2003 to
$142,279 at December 31, 2004. During the first half of fiscal 2005, the Company
used $247,477 of cash to fund its operating activities and $30,395 for the
purchase of tooling and patent related expenses.

LGA Capital Requirements

During the second Quarter of fiscal 2005, LGA sold 1,250,000 shares of common
stock to an existing LGA shareholder, for $250,000, or $0.20 per share. In
conjunction with this sale, LGA negotiated a call option for these shares that
grants LGA the right for two years following the completion of this transaction,
to re-purchase any or all of these shares at $0.40 per share.

The Company will need to raise additional operating capital from either
financing activities or from product licensing revenue to fund the Company's
growth through the end of the 2005 fiscal year. The Company is currently
increasing its product inventory and higher inventory levels will also increase
the use of cash until the inventory is sold. Currently, LGA intends to add
approximately $100,000 of inventory to its books over the next 120 days. In
addition, the Company will incur higher operating expenses into the future for,
among other reasons, an increased focus on selling, product fullfillment and the
personnel necessary to support this growth.


The Company is working on several product licensing opportunities, that if
completed, have the potential to generate significant growth capital for our
business. However, no assurance can be given as to whether these discussions
will result in a completed transaction, nor can the Company give any assurances
as to the timing or financial magnitude of these transactions.

Due to the  timing of  anticipated  inventory  additions  and  higher  operating
expenses, the Company will need to raise capital, in addition to the recent
private placement, from either financing or licensing sources during fiscal
2005.

The Company is experiencing a growing level of product interest from consumers,
dealers and OEM's. It will take time and capital to convert this interest into
product sales and/or licensing revenue. Therefore, even though the Company
anticipates higher sales revenue going forward, it is not able to forecast when
its sales volume will be sufficient to support the Company's operating expenses.
Therefore, for the next two quarters LGA will pursue raising additional growth
capital from either finance or licensing related sources. There can be no
assurance given as to whether LGA will be successful at generating the
additional growth capital it will need from either of these sources.

While a portion of the current liabilities, approximately $88,278, is owed to
present officers and/or directors, there can be no assurances that these
officers/directors will not seek payment in the near term.

Inflation has not had a significant impact on the Company's operations.

CONTROLS AND PROCEEDURES

Rule 13a-15 or Rule 15d-15 under the Exchange Act, the Company's Chief Executive
Officer and Treasurer believe that the Company's controls and other procedures
that are designed to ensure that information required to be disclosed by the
Company in the reports that it files or submits under the United States
securities laws is recorded, processed, summarized and reported, within the time
periods specified in the Commission's rules and forms were adequate as of the
end of the period covered by this Form 10-QSB. Disclosure controls and

appropriate to allow timely decisions regarding required disclosure.
