On

HAPC,

Iceland

Acquisition

Subsidiary,

Inc.,

InfuSystem

and

I-Flow

entered

into

a

non-binding

Memorandum

of

Intent

(the

“MOI”)

which

contemplates

an

amendment

to

the

Stock

Purchase

Agreement,

dated

as

of

September

29,

2006,

by

and

among

the

foregoing

parties,

pursuant

to

which

the

original

purchase

price

payable

by

HAPC

to

I-

Flow

for

InfuSystem

would

decrease

from

$140,000,000

to

$100,000,000.

The

cash

portion

of

the

purchase

price

payable

to

I-Flow

will

remain

at

$85,000,000,

less

the

amount

returned

to

stockholders

of

HAPC

exercising

their

conversion

rights

as

described

in

HAPC’s

Definitive

Proxy

Statement.

HAPC

will

also

deliver

a

promissory

note

to

I-Flow,

the

amount

of

which

will

range

from

$15,000,000

to

$35,000,000

depending

upon

the

number

of

HAPC

stockholders

who

exercise

their

conversion

rights.

The

MOI

contemplates

that

HAPC

would

pay

contingent

consideration

to

I-Flow,

provided

that

certain

conditions

related

to

the

operations

of

InfuSystem’s

business

are

met.

The

contingent

consideration

would

be

based

upon

the

compound

annual

growth

rate,

or

“CAGR”,

of

HAPC’s

consolidated

revenues

over

the

three-year

period

ended

December

31,

2010

and

would

be

paid

in

2011.

No

additional

payment

will

be

made

unless

HAPC

achieves

a

revenue

CAGR

of

at

least

40%

over

the

three-year

period.

The

payment

will

range

from

$3,000,000

to

$12,000,000

depending

upon

the

extent

to

which

revenue

CAGR

for

the

three-year

period

exceeds

40%.

The

maximum

potential

amount

of

the

contingent

consideration

is

$12,000,000

and

would

be

payable

to

I-Flow

if

HAPC

achieves

a

revenue

CAGR

of

50%

over

the

three-year

period.

The

parties

to

the

MOI

have

not

yet

amended

the

Stock

Purchase

Agreement

to

reflect

the

contemplated

changes

in

the

consideration

payable

by

HAPC

to

I-Flow

for

the

acquisition

of

InfuSystem,

nor

are

the

parties

under

any

obligation

to

enter

into

such

an

amendment.

Continuous infusion cancer treatment

Continuous Infusion (CI) allows for gradual administration of chemotherapy via a

small portable pump over several days as opposed to traditional chemotherapy

treatments given in a single high dose over a short period of time (known as bolus

infusion)

CI has achieved increased acceptance and is becoming a market standard of care

for colorectal cancer (CRC) due to:

–

Increased efficacy and comfort for patients (lower toxicity)

–

Lower cost compared with hospitalization or home care

–

Higher margin to physicians due to changes in Medicare reimbursement

In 2004, sanofi-aventis and Pfizer introduced CRC treatment protocols FOLFOX and

FOLFIRI, which include courses of CI. Their marketing efforts have helped to

increase physician awareness of CI.

There are currently over 120 CI drug therapy clinical trials in progress

Recent drug protocol approvals for head and neck, lung, pancreatic, gastric and

other cancers
