Indications for Use

Over the Counter, OTC: Bleed-X™ is intended as a topical dressing for the local management of bleeding wounds such as minor cuts, lacerations and abrasions. Prescription, Rx: Traumadex™ is intended as a topical dressing for the local management of bleeding wounds such as cuts, lacerations and abrasions. Under the care of a health care professional, Traumadex™ may be used for the temporary treatment of severely bleeding wounds such as surgical wounds (post-operative, donor sites, dermatological), cuts, lacerations and traumatic injuries.

Device Story

Bleed-X and Traumadex consist of dry, sterile, spherical particles made from purified plant-based polysaccharide. Particles act as molecular sieves, excluding large proteins and cells. Upon contact with blood, particles rapidly dehydrate blood, causing hemoconcentration; serum proteins and cells form a viscous gel. Normal platelet activation and fibrin deposition within this gel create a tenacious clot to limit bleeding. Used in clinical or home settings; applied topically to wounds. Benefits include accelerated bleeding control. Device is provided in single-use containers or applicators, terminally sterilized via gamma irradiation.

Clinical Evidence

Clinical investigation using human subjects in a side-by-side comparison of Bleed-X/Traumadex against a control of normal clotting demonstrated an accelerated rate of bleeding control in the presence of the particles. Animal testing using a porcine model also confirmed efficacy in bleeding control.

Technological Characteristics

Dry, sterile, spherical particles of purified plant-based polysaccharide. Controlled porosity via emulsion cross-linking process. Biocompatibility per ISO 10993-1 and FDA G95-1. Sterilization via Cobalt-60 gamma irradiation per AAMI/ANSI/ISO 11137 and EN552 (SAL 1x10^-6). Packaged in medical-grade plastic applicators or laminate pouches.

Indications for Use

Indicated for local management of bleeding wounds including minor cuts, lacerations, and abrasions (OTC). For prescription use, indicated for temporary treatment of severely bleeding wounds including surgical wounds (post-operative, donor sites, dermatological), cuts, lacerations, and traumatic injuries under professional care.

Regulatory Classification

Identification

#### 4. Description

Meclafor, Inc.'s Bleed-X™ and Traumadex™ consists of dry, sterile, controlled porosity, spherical particles manufactured from purified plant based polysaccharide. The porosity is controlled such that the particles act as molecular sieves excluding large proteins and cells.

The bleeding ccssation is accomplished by the rapid dehydration and subsequent hemoconcentration of blood in contact with the particles. The concentration of serum proteins and cells produces a viscous gel. Normal plateler activation and fibrin deposition within the congealed blood produces a clot that limits further bleeding.

#### 5. Indications

#### Over the Counter, OTC:

Blocd-X™ is intended as a topical dressing for the local management of blocding wounds such as minor cuts, lacerations and abrasions.

#### Prescription, Rx:

Traumadex™ is intendod as a topical dressing for the local management of bleeding wounds such as cuts, laccrations and abrasions. Under the care of a health care professional, Traumadex™ may be used for the temporary treatment of severely bleeding wounds such as surgical wounds (post-operative, donor sites, dermatological), cuts, lacerations and traumatic injuries.

#### 6. Substantial Equivalence

This section summarizes information about the product and outlines the tests and clinical

information we believe will provide sufficient data to support our claims of efficacy and

safety.

Medafor, Inc.'s Hemadcx cloting beads consists of dry, sterile, controlled porosity, spherical particles manufactured from purified plant based polysaccharide using an emulsion cross-liking process.

The particles will be packaged in single use containers with a moisture-protective laminate outer wrap. The final package will be terminally sterilized using gamma irradiation. Contract manufacturers will do both packaging and sterilization, following written contracts with Mcdafor.

{2}------------------------------------------------

#### Page 21

Contract manufacturers will do both packaging and sterilization, following written contracts with Medafor.

Bleed-XTM will be available for OTC use in sizes from .5 to 10 grams using a medical grade plastic applicator package or a "peel and pour" laminate pouch.

Traumadex™ will be available for prescription use in sizes from 1 to 10 grams using a medical grade plastic applicator.

The hemostatic effect of the particles is produced by the rapid dehydration and subsequent hemoconcentration of blood in contact with the particles. The concentration of serum proteins and cells produces a viscous gel. Normal platelet activation and fibrin deposition within the congealed blood produces a tenacious clot that limits further bleeding.

Biological testing per ISO 10993-1 and FDA G95-1 demonstrates the biological compatibility of Bleed-XTM and TraumadexTM.

Sterilization validation of the Cobalt- 60 gamma irradiation process per AAMI / ANSI / ISO 11137 and EN552 demonstrate a sterility assurance level (SAL) of 1 X 10-6.

Animal testing using a porcine model shows the efficacy of Bleed-XTM and Traumadex™ in the control of bleeding.

A non-significant risk clinical investigation using human subjects in a side by side comparison of Bleed-X ™ / Traumadex™ and a control of normal clotting demonstrated an accelerated rare of bleeding control in the presence of the particles.

The initial indications are for topical application as an aid in the control of bleeding. This product will be intended for both prescription and OTC use and labels is worded accordingly.

Medafor, Inc. believes that as a result of the biocompatibility testing, the physical analysis, the animal studics and the human clinical that the Bleed-XTM and Traumadex™ containing Hemadex™ clotung beads are safe and effective for the control of bleeding wounds and perform in a manner equivalent and similar to the predicates. The device has been shown to effectively control bleeding. It has been demonstrated to be biocompatible per an internationally recognized standard and it has demonstrated to be procedurally and physiologically appropriate in medical upplications.
